Abstract： |
The air conditioning unit is composed of the outdoor unit and the water loop. The outdoor unit includes the compressor, the four-way valve, the heat exchanger, the fan, the liquid-vapor separator, the closed type trough for storing ice, the solenoid valve and the electric control valve. The water loop includes the tail end of the unit, the water collector, the water separator and the water constant pressure part. The water in the closed type trough is connected to the water in the water loop of refrigerant/water heat exchanger so as to form the loop locked outer melting ice system. The invention prevents shortcomings of water reverse flow and large hydrostatic pressure on the solenoid valve etc. and raises evaporating temperature so as to save energy. The unit provides five modes of operation: storing ice, melting ice and cooling, cooling only, united cooling and heating. |
