Abstract
The utility model relates to a water heater unit with a spray liquid enthalpy-increasing heat pump, belonging to air conditioning equipment. The water heater comprises a cooling pipe system and a heating pipeline system. In the water heater, an economizer (24) is arranged, an evaporator adopts a side heat exchanger (25), a condenser adopts air-cooled heat exchanger (20), an air outlet (2) of a compressor is connected with the inlet end of a four-way valve (7) by pipes and an outlet at one end of the four-way valve (7) is connected with the inlet end of a domestic hot water heat exchanger (16) by pipes. Under the condition of relative low evaporation temperature (below -25 DEG C), liquid refrigerant from the condenser passes through the economizer, then one part of the liquid refrigerant absorbs heat with the method of self-throttling evaporation so as to undercool the other part of the liquid refrigerant and to perform reinflation and circulation for the compressor. Utilizing the economizer to perform reinflation and circulation can improve the compression refrigeration cycle efficiency of the compressor, increase cooling capacity, and reduce the exhaust temperature of the compressor so as to improve the COP (coefficient of performance) of the unit.
