Application Research on Recovery Fresh Air Heat Pump Units in Energy Efficient Buildings
In the winter of cold and serious cold regions of china, the exploration and research on new systems and new equipment suitable or compatible the thermal comfort, the indoor air quality (IAQ) and the energy conservation are the urgent requirement for sustainable development of energy efficient buildings.For solved such issues,designed the recovery fresh air heat pump units,that inducted exhaust into evaporator of heat pump,recovered the energy of exhaust by heat exchange, and heated fresh air used condenser of heat pump.Used the enthalpy difference method experiment,that contrasted two conditions of building exhaust only and building exhaust mixed outdoor air. Measured the heat quantity, the electricity power, the coefficient of performance (COP) and the recovery efficiency.The result showed that in the same surroundings and the electricity power, the quantity of heat is increased and the COP averaged 4.3 the top is about 4.75. The recovery efficiency averaged 40％, the top is about 51％.Make use of the exhaust fully, raise the intake air temperature of heat exchanger, can prolong the recovery fresh air heat pump units runnJng time,guarantee well IAQ in the energy efficient buildings in winter.
