Air source water chiller and its mode of operation

An air source water chiller, it's a four-way valve port and an exhaust port connected to the compressor, b and hot water heat exchanger connected to the interface, c interfaces and cold heat exchangers, compressor return air inlet connection, d Interface and radiator connection, hot water heat exchanger is connected to the anode end of the one-way valve, the check valve cathode terminal of the first electronic expansion valves, electronic expansion valve connected to the second, the first electronic expansion valve, the second electronic expansion valves, respectively , radiator connection with the cold water heat exchanger, hot water heat exchanger and heat pumps, hot water tank and the first flow switch connected to form a circulation circuit, a second heat exchanger and the cold water flow switch, cooling water pump and cooling water tank connected to form a loop loop; hot water tank, the cold water tank hot water are provided with a temperature sensor, the cold water temperature sensor. An air source water chiller modes of operation, including hot + cold water, cold water, hot water and stand four modes of operation. The present invention is by detecting the hot water tank, the cold water tank temperature in real time, and the set temperature compared with the hot water tank and cold water tank, determined to achieve the operating mode of the unit.
