A direct evaporative closed external ice-heat pump air conditioner comprises a compressor, a four-way valve, a heat exchanger, an air-cooled heat exchanger fan, a high-pressure receiver, a dry filter, a liquid electromagnetic three- Through the valve, a plurality of expansion valves, a plurality of one-way valve, refrigerant / water heat exchanger, gas-liquid separator, closed ice storage tank, solenoid valve and motor valve control valve composed of outdoor unit and the air conditioning terminal Water, water separator, air conditioning water pressure components composed of air conditioning water circuit. The water in the closed storage tank communicates with the water in the water circuit of the refrigerant / water heat exchanger air conditioner and forms a closed loop external ice melting system. The invention avoids the defects of water flow backflow and electromagnetism valve and electric adjustment to bear the hydrostatic pressure and the like; the evaporation temperature of the refrigeration system is increased by 3-5 degrees Celsius on average, and the energy saving effect is obvious; the ice- Cooler alone for cooling, coolers and ice chiller cooling, cooling mechanism of the five operating modes. Save on heating equipment investment.
