The invention discloses a system and method for utilizing fresh air waste heat in a civil residence. The fresh air unit is connected with each residential house through air supply ducts and exhaust ducts. The split evaporator is connected to the fresh air unit through the fresh air switch valve and the exhaust switch valve, and the split evaporator is connected to the outdoor through the outdoor communication pipeline. The fresh air inlet and exhaust air outlet of the fresh air unit are respectively connected to the fresh air bypass valve and the exhaust air bypass valve. The refrigerant inlet and outlet of the split evaporator are connected with the outlet of the electronic expansion valve and the inlet of the scroll compressor. The outlet of the scroll compressor is respectively connected with the inlet of the electronic expansion valve through the heating and condensing heat exchanger, the thermal storage type domestic hot water tank. The water supply and return ports of the thermal storage domestic hot water tank are connected to the residential houses through the domestic hot water supply and return pipes. The water supply and return ports of the heating and condensing heat exchanger are connected to each residential house through the floor heating supply and return pipes. Based on the air source heat pump, the invention realizes the effective recovery and utilization of the waste heat of the fresh air system of the civil residence.
Description
technical field [0001] The invention relates to a system and method for utilizing fresh air waste heat in a civil residence realized by utilizing an air source heat pump, and belongs to the field of fresh air energy recovery and utilization. Background technique [0002] In recent years, in order to pursue the comfort and health of residential buildings, more and more buildings have designed central heating and cooling and central domestic hot water systems. Among them, the floor radiation + fresh air method is mostly used for central heating. Usually, the floor radiation system is responsible for the basic Heat load, the fresh air system undertakes the functions of ventilation and humidification. In winter, the outdoor cold air is sent into the room in an organized manner after dust removal, filtration, humidification and temperature adjustment through the fresh air unit, and at the same time, the dirty indoor air is replaced and discharged in an organized manner.
