(music enjoying) (Narrator) Over 50 percentage of thegreenhouse fuel emissions you produce to your house are generated by means of heating,air-con and sizzling water. In other phrases keepingyour house warm in winter, cool insummer with quality hot water on faucet is emitting2.5 to five tonnes of greenhouse gasemissions each and every year. It also contributes ahefty amount to your electrical energy bill, between50 to 60 percentage. CSIRO has invented a new solarair conditioning system for Australian houses.This science answer will lower Australias emissions,cut down your vigour expenses and cut back our demandfor electrical power and fuel. If every residence inAustralia set up our sun cooling technologyit will be the equivalent of saving15 mega tonnes of CO2 or taking three.5 millioncars off the avenue. CSIROs solar air conditioningis an progressive three in a single technology that provides hotwater, cooling and heating. It makes use of handiest a fraction ofthe electrical energy of current techniques and halvesgreenhouse gas emissions. The procedure starts with peculiar sun scorching water approach. Water is heated by way of solar panelsand stored in the hot water tank.This solar scorching water canthen be used for the duration of the dwelling, reducing the needfor fuel or electrical energy. A component to the scorching water isdiverted into CSIROs new sunlight air conditioning unit, which isdivided into two cubicles. The sizzling water entersa heat exchanger within the first compartmentof the unit. Similar to a auto radiator the heatexchanger makes use of the sizzling water to warmth external air that hasbeen drawn into the primary compartmentthrough the vent.At the same time outsideair is also being drawn into the second compartmentinto a desiccant wheel. The desiccant wheel is the mostcritical a part of the system. It is used to dry out the airbefore it goes into the condo. Slowly turning thedesiccant fabric in the wheel continuouslyabsorbs moisture within the 2nd compartment andthen the absorbent material dries out inthe first compartment. The desiccant fabric is dried outusing the scorching dry air generated by the warmth exchanger. This air is then exhaustedoutside the dwelling.The dry air from the desiccantwheel flows through an oblique evaporative cooler which createsa circulate of cool dry air. This cool dry air is then fed into thehome in order to settle down the rooms. In iciness the sunlight heated air canbe used straight to heat the condo. CSIROs sunlight coolingsystem is a low emissions substitute to conventionalair conditioning and fuel or electrical powered heating,delivering extra secure homes, reduced energy billsand a cooler planet..
