The heat pump can recover waste heat below 100 ℃, is energy-saving equipment for efficiently utilizing low-temperature heat energy, and is applied to the aspects of heating, air conditioning, drying, dehumidification, drying and the like. However, the existing geothermal multi-energy complementary heat pump heating system in northern severe cold areas has low diagnosis efficiency on heat pump faults in winter; meanwhile, the heat pump cannot be effectively dedusted.
