AIR DISTRIBUTION METHODS FOR DOMESTIC WARM AIR HEATING SYSTEMS USING LOW GRADE HEAT SOURCES. TESTS WITH LOW LEVEL AND HIGH LEVEL AIR SUPPLY TERMINALS
The performance of a domestic warm air heating system that utilises a low grade energy source was investigated in a simulated living room of a low energy house. Because of the high air change rates associated with low grade energy sources, the main emphasis in this work was on studying different methods of discharging large air flow rates into the heated space without creating unacceptably high air velocities in the occupied zone. The limits of air flow rate and supply temperature within which thermal comfort was maintained were determined for direct discharge into the occupied zone at low level, discharge across a wall at low level and high level discharge outside the occupied zone. These limits were defined by applying Fanger's comfort criterion to the thermal environment in the occupied zone for the UK winter design heating load condition. The results indicate that some low grade energy sources could, with adequate control procedures, provide comfortable thermal environment in a low energy house.
