[0002] A heat pump is a highly efficient energy-saving device that makes full use of low-grade thermal energy. Heat can be spontaneously transferred from a high-temperature object to a low-temperature object, but cannot spontaneously proceed in the opposite direction. A fresh air fan is an effective air purification device that can circulate indoor air. On the one hand, it discharges the polluted air indoors to the outdoors, and on the other hand, it inputs the fresh air outdoors into the room after sterilization, disinfection, filtration and other measures, so that the room is filled with fresh and clean air at all times. A heat pump fresh air all-in-one machine is a machine that integrates a heat pump and a fresh air fan.
