Heat pump system and energy storage equipment

Abstract

The utility model discloses a heat pump system and energy storage equipment. The heat pump system comprises a compressor, a heat exchanger, an economizer, a first electronic expansion valve and a fluorine cooling plate which are sequentially connected. The compressor is provided with an inlet, an outlet and an enthalpy spraying opening, and the inlet, the enthalpy spraying opening and the outlet are sequentially arranged in the flowing direction of refrigerants in the compressor. The heat pump system further comprises an enhanced vapor injection loop, one end of the enhanced vapor injection loop is connected with the economizer, and the other end is connected with the enthalpy injection opening. The economizer is used for vaporizing the refrigerant, and the vapor injection enthalpy increasing loop is configured to enable the vaporized refrigerant to be injected into the compressor through the enthalpy injection opening. According to the heat pump system, the enhanced vapor injection loop is arranged, under the condition that the air return amount of the refrigerant is guaranteed, the refrigerant is directly injected into the middle position in the compressor through the enthalpy injection opening, the refrigerant enthalpy injection effect in the compressor can be improved, the refrigerant circulation amount is increased, the refrigerant does not need to be heated in an electric heating mode, energy consumption is low, and cost is low. Therefore, the heating capacity of unit volume is improved, and the heat pump system has good low-temperature heating capacity.
