Total heat recovery water cycle central air conditioning unit

2013 
The utility model provides a total heat recovery water cycle central air conditioning unit which comprises a refrigerant loop and a first water cycle loop. The refrigerant loop comprises a compressor, a first heat exchanger, a first check valve, a liquid storage pot, a filter, a second check valve, a first expansion valve, a second heat exchanger and a gas-liquid separator, wherein the compressor, the first heat exchanger, the first check valve, the liquid storage pot, the filter, the second check valve, the first expansion valve, the second heat exchanger and the gas-liquid separator are connected in sequence, an outlet of the gas-liquid separator is connected with an inlet of the compressor, and the second heat exchanger is a water-cooled heat exchanger. The first water cycle loop comprises a first water pump, a fifth heat exchanger and the second heat exchanger, wherein the first water pump, the fifth heat exchanger and the second heat exchanger are connected in series to form the loop. The total heat recovery water cycle central air conditioning unit is provided with the independent first water cycle loop to conduct heat transmission, can remotely transmit heat or cold quantity, greatly reduces usage amount of refrigerant, reduces refrigerant pipeline equipment, and reduces production and installation cost.
