What HVAC Means For Indoor Growers

– hiya guys, this is Nate Storey with BrightAgrotech and at present we will do a fast video on HVAC and what it manner to indoorgrowers. HVAC is heating, air flow, and air-con. What it describes is the systems that takeindoor air circulate it around, deal with it, and both cool it down, warmth it up, or dehumidifyit. Most growers use HVAC someway shape orform. Especially as you get increasingly intensive,HVAC becomes increasingly relevant to the success of your operation.If you are doing an extraordinarily very small setup, youmay get away without utilizing HVAC, however the larger you get, once you start doing CO2 supplementation,whenever you start to truly dehumidify your air particularly aggressively or cool your air becauseyou’ve acquired so many lights. HVAC turns into a important a part of your operation. HVAC is an highly-priced cap ex and it can bea relatively cost operating rate as good. HVAC shouldn’t be low priced certainly as we get moreand extra intensive as we cram extra plants into less area we’ve got extra problems with humidity. We now have more issues with mildew and fungi andall of the style of matters that happen once we just cram a lot of crops collectively.We even have so much much larger cooling costsfor most growing environments. That is just given that once you cram these plantstogether and particularly mild them up, you create various warmness that you just ought to maintain. You recognize, systems vary in satisfactory, and theyvary in fee. Finally they’ll be within a certainrange. Now the big difference in my intellect and in ourminds, is between traditional condenser centered air conditioner methods and water chillers. We tend to move extra toward water coolingthan air cooling. The motive that we do that’s, we like towater cool our lights.It gives us somewhat bit extra manipulate overthe developing environment and we now have determined that we can absolutely run a entire bunch of othertypes of gear on chilled water just a little bit less complicated, extra successfully as a grower,than we are able to with these giant cumbersome air-con techniques. One factor you need to thing about with HVACis your intent to scale and that is anything that you simply must be desirous about if you intendfor your farm to be loads better down the road, than i’d spend money on a higher qualitysystem that may be scaled over time. That you may buy some relatively small low priced options,however those are relatively best dependable or plausible on an awfully small scale so when you intend toget significant, if you wish to make cash, if you need to scale your facility, it’s worthputting apart a budget only for HVAC. Yeah there are plenty of approaches that you may reduceyour HVAC expenditures. The simplest means is to only relyon quite a lot of ventilation if you’re in an field where the air is most often cool sufficient thatyou can cool your facility with external air.Now that introduces all types of other problems,proper. Which you can bring in pests, it is an imperfectsolution on the grounds that normally it can be very scorching external and it can be very scorching inside, however ultimately youknow that’s by way of far the most affordable option to get a few of this work completed. Most people which are fairly critical that wantfine tuned and high phases of manage, have to go over to a industrial HVAC method. Those come to be rather more costly. Now how steeply-priced it is eventually dependson how giant the method is, so the greater the procedure is, the more cost-effective it will get on a per tonbasis. Additionally then the neighborhood installation bills andwe’ve observed these to be very variable throughout the U.S. And internationally. For most growers that you would be able to get into pretty reasonablesystems in case you have a moderately huge setup. One factor that we now have quite checked out is howwe take five and 7 ton chillers and use mixtures of 5 and 7 ton chillersscaled to cool very tremendous facilities effectively. If you have already got a process for heating andcooling, then you definitely sort of already have some stage of rudimentary HVAC.Now the query to ask yourself is whetheryou could get more out of it, if it was an HVAC system that was quite intent builtfor your facility. That implies intent built for air filtration,rationale built for dehumidification, cause constructed around the apparatus that you are walking. If in case you have so many lights for your atmosphere, what kind of BTU’s you are producing and you could measurement your HVAC process correctly. These are the sorts of matters that you reallyneed to be serious about. We find irresistible to do one of the HVAC ourselves orat least scale back the price of HVAC by way of utilizing water chillers to sit back our lights. We will do this typically all in residence andthat reduces our total HVAC fee drastically. Depending in your lighting variety and dependingon your main issue, those fees can be pretty darn high. Peculiarly once you get in to reason builtsystems. However, i would say that many of the timea intent built system is worth it.There are tons of resources available in the market on HVACif you want to gain knowledge of more. There are increasingly more and more of thesebecoming on hand. The first position i might go is to Upstart Universitywe’ve acquired a quality webinar up at Upstart university. I feel it is 10 bucks to entry the webinar. It is usually 10 bucks for a month subscriptionto USU and it can be free through USU so it can be more often than not worth just getting a month subscription toUpstart university and staring at the webinar and then of direction trying out a few of theother resources there.We additionally could have some web publication posts coming outon this area, so we’re going to try to get you the first-rate viable information throughthe blog. Be certain you verify that out. Thank you guys a lot for staring at and asalways please subscribe, subscriptions are how we measure our success. It’s how we measure whether or not what we’re producingis whatever that you simply guys want and whatever that you simply guys want.It’s also a method for us to get you the mosttimely and the quality viable knowledge to you instantly as an alternative of getting to head out andtry and find this crazy stuff on the intertubes. Be certain you tune in, be certain you subscribe,and we will seem ahead to getting a lot more exceptional content material to you sooner or later..

Modern Group and Efficiency Mechanical on Air Conditioning MGTV Episode 2

Hello i’m Cindy Christie and you are watchingMGTV. In this episode we’re gonna study aboutindoor air first-rate and why it can be such an predominant a part of the modern staff’sperformance build method. In assembling a successful staff, it is vitalto the ultra-modern crew that their properties are not most effective vigor-effective but they are are also cozy to livein and healthful too. Partnering with experts to make suretheir home owners receive the very best is necessary to the modern crew’s RDHendrickson. And in designing the superb in-homeenvironment, efficiency Mechanical is on the high of his record. Constructing astrong group is at the core what we do here on the trendy group. Our strengths come from our outstandingpartner that add a stage of competencies that our consumers each become aware of and admire. This synergy is what’sallowed us to set our pursuits so excessive. One in all our key partners is EfficiencyMechanical who takes care the properties atmosphere. I’ve worked with Troy cook for many years and he and his team arehuge a part of our efficiency building method.The challenges you have got with an energyefficient condominium and an extraordinarily tight condominium when it’s sealed and foamed on the roofdeck is the fact that you haven’t any air trade, so thatair may be very, very stale. So what we did the Ash task is two fold. We absolutely have air coming from theoutside being exchanged so you constantly have fresh air coming into the house and you’ve got stale air being exhausted. With the air that’s being brought in, we even have an air provider/air purifierthat’s washing and cleansing all of the interiorair on top of that, so you’ve got the freshestand cleanest air you can with very excessive effectivity and a sealed envelope. The buildingenvelope is the most important thing within the apartment if in case you have heat that will get into the drywall you’re finished. There’s nothing you are able to do, you are not gonna discontinue it.You’re placing more effective equipmentin but your consistently overcoming that so your airconditioning load your tonnage of air-con has tobe increasingly and extra. We fairly constrained our amount of airconditioning we wanted considering that the constitution is so effective. We alsohave zone dampers in there so each room has its possess separate manipulate.You can be able to manage something room inside that house at 75 or if someone needs it at seventy eight, you are able to do that. At effectivity Mechanical and ModernGroup what we quite care about is remedy, wewant our customers to be at ease. Because you’ve got a true variable-speedunit the unit is running always but it surely’s runningat this kind of small kilowatt usage that you do not even know it’s on. Soyour alleviation is maintained continuously. As far as external air infiltration that ties in to relief aswell. You wish to have your air to be easy and youwant it to be as cool and as comfy as you want it to be. So that you would not have temperature swings atall with the service inexperienced speed.The purpose that is important to get thestructure sealed and put probably the most efficient gear inis it can pay for itself. Air conditioning and insulation are theonly two matters in a house that pay for themselves at any time when. Utilising andinstalling top-tier products is best the you have to ensure they are operatingat their peak for highest comfort too. For this, the latest crew turns to their go to performance consultant Earthwise building Science team. Right here’sShawn Mullins to tell us more. Looking again, when I first becameinvolved with RD and today’s crew probably the most matters I used to be pleased as aconsultant and verifier to search out used to be they already had numerous the basics down. They knew about tight building envelope they knew about waterproof barriersthey’ve been enforcing specific types of building envelopes andkeeping it back inside conditioned house for relatively awhile. Those forms of things particularly lend themselves to a tightenergy-efficient cozy dwelling with fairly excellent indoor air quality. It’simportant from a advisor and a verifier perspective as good as from the homeowner standpoint to be equipped to experiment for one-of-a-kind phases of performanceso that we will actually validate how a home is performing sowhen a customer wishes to grasp what do they assume the vigor bill are going to be we are able to inform them.Should you don’t do thediagnostic testing and performance all that you may say is it can be higher thanmaybe a commonplace house however you can not quantify it. The quantifying side on that involvesdoing blower door checking out where we’re genuinely measuring the amount of air infiltration doing some duct testing we’re measuringthe quantity of duct leakage that is in the home and then definitely visual inspections werewe’re making sure that detailed accessories are there. Cutting-edge workforce is doing pleasant and onethings that they may be imposing is even throughout the development of the constructing we’re doing some quality testing just to make sure that they are on the correct track and once we do the ultimate experiment is goingto be the place we want to be. That is it for this time. Be certain to checkout ModernGroupTV.Com for all the latest understanding on the trendy team and their group of professionals. I’m Cindy Christie and i will see you next time on MGTV. Good well in and.

HVAC Design, Understanding Heating, Ventilation, & Air Conditioning Systems

As we move along the path to a Net Zero Energy Building, we can vastly lower our energy demand using passive strategies. But it may not be enough. If you cant entirely achieve thermal comfort passively, youll need to make up the difference with active HVAC systems. People’s thermal comfort mainly depends on temperature and humidity. When outside air is too hot or too cold, or the humidity is too low or too high, youll have to condition the outside air as you bring it into the building. Of course, people also need fresh air.And air circulation plays a key role in thermal comfort too. Moving air can help people feel cooler, even if the temperature is higher. But you can also use other forms of heat transfer besides air to improve efficiency. Radiant floors, panels or beams are usually heated or cooled by liquid; then they radiate energy directly to people and objects, avoiding the need to heat or cool all the air in the space. No matter what equipment you use, you want to size it correctly and choose components with the highest energy efficiency ratings. For instance, heat pumps are rated by Coefficient of Performance, or COP.It’s the amount of heat energy moved, divided by the energy used to move it. Its also important to optimize the whole system, and not just its parts. For example, don’t throw away the energy you already spent heating or cooling the inside air when you bring in fresh air. Heat exchanging systems can recover that heat, coolness, or even humidity before the airs exhausted. And remember, the better controls and feedback you have, the more you can save energy while still keeping people comfortable, as both the weather and the building use changes.So keep looking for passive strategies… Those will get you a long way on your path to Net Zero Energy Buildings. But smart active strategies are often needed to get you all the way there. Its the combination of the two that makes Net Zero Energy Buildings achievable!.

HVAC Engineering Technology program (HET) at CLC

Our HET program is designed to teach thestudents anything dealing with heating, cooling, ventilation or airconditioning. We have high school students coming in, and we have peoplecoming into our program to change careers. They will start out with verybasic circuits, working with series, and parallel type circuits, and then work upinto a complete heating cooling system. The skills they can build up and leadinto can be anywhere from very basic, from working on houses to working inindustrial buildings. We have very high tech equipment from high efficiencyheating and cooling units. Wireless digital type controls. So they’re gettinghands-on experience as they would find in the field. What they love of ourprogram is the hands-on portions of it. Not many schools in the country havewhat we have here.One of the greatest things about the HVAC program is thatit’s a growing field. People can come in to field and expect to leave with the skillsto be able to make an income, they could take care of family. Our tuition isextremely low and most our instructors have over 20 years in experience. Theway our program is built is that we have stackable certificates and each one ofthose certificates will step right into a AAS degree.If I could say one wordabout this career, it would be life-changing..

eLearning Module: DriveWizard HVAC – Tools

Hi, I’m Paul Avery I’m a Product Training Engineer with Yaskawa’s Technical Training Services This video explains how to utilize DriveWizard HVAC ‘s Application Wizard and the Convert Project Tool. Under the Tools tab in DriveWizard HVAC you will find the Application Wizard. The Application Wizard will step a user through the drive setup process by asking them a series of relevant questions and then configuring the proper parameters automatically. It can be very helpful for people that are either intimidated by the breadth of parameters in the average drive or people that want to make mostly typical adjustments for their application and want them all put in one place.Now if you have already changed any parameters in your drive when the Start button is clicked you will receive a message asking if you would like to initialize the drive or not either click Yes to start out with a clean slate or select No to leave the existing Modify Parameters alone Using the Wizard as a Simple Task instead of looking at a long list of parameters and numbers the Wizard breaks down setup into simple steps. Parameter settings have drop-down menus and also helpful descriptions. Additionally, there are graphics to give you a better understanding of how you might need to set up a particular function. Once you reach the end of the Wizard there is an option to save the parameters to the Active Project only or to write them to the Connected Drive as well as save them to the project.At this point the Wizard prompts you to perform an Auto-tune. Auto-tuning is only an option and is not required. There is also a Convert Project Tool available in DriveWizard HVAC. This tool can convert an older generation project file to the 1000 generation equivalent automatically. Throw out that pen and paper because this tool makes updating legacy applications easier! The tool will automatically select a new model number based on what the old drive was so be sure that the correct new drive is selected before converting the project.Click the Go button and the process will start. At the end of the conversion you can view a Conversion Log which will list the Parameters and Settings that have been converted. After reviewing the Log, transfer the Parameters to the project and all you have left is to write the Project File to the new drive. If you have any questions about the information presented in this eLearning Module please feel free to contact Yaskawa’s Technical Support Group either by phone, email or via our website.Thank you! you.

Certificate Program for HVAC

<> AJ: My name is AJ and I’m 40 years old and I work with A1 heating, ventilation, and electrical. I had brain surgery about 10 years ago. I had bacterial meningitis and I had some brain damage as a result. I was a reporter. I was a writer and after the surgery, I just I didn’t have the mental capacities that I had before I got sick. So I had to do something different. my concerns were what was I going to be able to do, what could I no longer do, and in an employment environment being aware of your capabilities and the things you can and can’t do, it’s pretty important.I had been working with Nebraska VR for a little while after I got sick. And my counselor at Nebraska VR actually told me about the certification program. Carly: Certificate programs – they’re a short-term hands-on training program, they’re business led and so often times businesses come to VR and express a need of a high turnover area. In this specific one, it’s the HVAC helper position. Dana: What I find special about the certificate program is that it helps an individual who may not be ready for that post-secondary training, those associate degree programs, or bachelors programs. And they’re able to get to showcase their skills to an employer and be able to start working right away after the training is completed.AJ: My interest in the Nebraska VR Certification Program was learning a trade. I wanted to learn something that was going to last me for a long time. They had a few options for the certification program and the HVAC certification sounded like the best fit. Dana: We did some assessments to identify his ability to measure, which is a very important skill within this type of employment. There’s a lot of spatial aptitude that’s required for this occupation as well as mechanical aptitude. AJ: It sounded like it was something that I could be good at it. Carly: He started the training program and from day one he was very motivated and said “I am going to succeed in this” and that was a great thing to hear from a student.AJ: It was really great to know that Carly was there. There wasn’t any kind of you know here’s this program go off and do your thing. She was there when we had classes and she she talked to A1. Carly: Once he started his OJE here, which is on-the-job experience, I was getting information from the employer, his teacher, him…making sure that it was a good fit for him. As well as making sure that at the end of this 10 weeks, he was employable.Jesse: Meeting AJ for the first time hearing his story it was amazing. I mean, you know, he got interested in the HVAC field and he’s been with us for a couple years now. You know, [he’s] been a great addition of this company and right now he’s actually taking classes with me during the week to actually go forward to take his journeyman class. Dana: I have seen a lot of growth in AJ since first meeting him. Initially, he came to me it was just really unsure what he wanted to do and then when he explored options more he found that working here with A1 was definitely his niche. Carly: When I first met AJ he was really motivated to learn this trade and seeing him working full-time now is great. But, I don’t see it ending there. Whether it be additional training or moving up within A1. I think it’s a great start for AJ but I don’t see him stopping anytime soon. Jesse: Everybody wants to work and make a living you know and in what is AJ’s passion for it was great and that’s why we brought him on. AJ: Nebraska VR has really helped me see there is a light at the end of this tunnel. There is a whole lot of options and a whole lot of possibilities of things I can do and places I can go with my experience. <>.

Good HVAC Design – White Board Series

– Hi, I’m Dave Phelps of ICF Homes. I’d like to welcome you to another episode of our whiteboard series. Today, I will talk about good HVAC design and convection in a house. In our illustration, weshow a typical two story house with a basement. In this series, we showeach level of the house second floor, first floor, basement has it’s own thermostat. And it’s tied back into the heat pump. Each of the thermostatsare smart thermostats, meaning they can talk to each other. As each level of the house needs specific heating or cooling, they will then send that signal back to the heat pump and the heat pump will move the air along. But one of the really neat features about good HVAC design is to use our steady basement temperature. And get that steady basement temperature all the way up to thesecond floor of the house. Because all the energy that requires is just the fan of the heat pump itself to move the air from the basement all the way up.And the way we do that, is a zone system. So for example, if thesecond level of the house in the summertime, we’vegot a 90 degree day outside. And we’re trying tomaintain 70 degrees inside. It’s gonna heat up on thesecond floor of the house. But we’ve got our steadybasement temperature, which by use of thesteady ground temperature of, we say, 55 degrees.This steady basement temperature, the air from the fanrunning on the heat pump will pull air in low in the basement. And it will pull it into the system and because the basementdoesn’t need cooling and the first floor doesn’t need cooling, the dampers here are closed. This damper up top opens up, and it blows out the air from the basement that moved all the way upto the top of the house that was already nice and cool, up to the top. It helped to cool thesecond floor of the house. If the first floor needs cooling, the same thing happens. This damper opens up andwe blow cool air out. The whole goal is to movethe air from the basement all the way up to the top of the house and back down, up and down. That’s really good convection in a home. Movement of the air around keeps the air very, very fresh and moving around. This is also the onlyenergy that’s required it’s just the fan of the heat pump.If for some reason weneed more cooling up top, the heat pump turns on. These dampers close. And it blows out more cool air at the top. And that is how we actually use our steady ground temperatureas a geothermal house. And we move the air throughout, and it is just a fraction of the energy to heat and cool a home if you utilize free energy. Most homes today, they donot have a zone system. There’s no damper here, and there’s no damper here. The duct work ends here. You only have one thermostaton the first floor of the house. You have another thermostaton the second floor. But you have your heatpump up in the attic. And this thermostat doesn’t go down. Actually the controlgoes up to the heat pump. Now, if the first floor needs cooling, it blows cool air out here, but it also blows coolair into the basement. The basement never needed it. And that’s why many homes the basements feel so cool in the summertime, and/or sometimes think cold is we’re getting coldair from the heat pump, it doesn’t need it.Because the first floor needed cooling, the basement didn’t need it. But most homes, the way they’re designed, cold air blows out in both areas. The other challenge ison the second floor, you’ve got your heat pumpup here in the attic, it could be 140 degrees in the summertime. And your heat pump isa 140 degree metal box. And you’re trying toblow 70 degree air out from a 140 degree metal box. They do it. It can be done. It takes an awful lot of energy to get air from 140 down to 70. That’s the way a lot of homes are, but it’s just not the mostefficient way to do it. This zone system, moving the air around throughout the house, it can be done whether it’s a conventional wood-framed house, or an ICF home.Thank you for your time. More to come. Have a good day..
