Water chilling unit based on hot moisture independent process as well as air-treatment method thereof

Abstract

The invention provides a cold water unit based on independent humidity control and an air treatment method thereof, relating to the cold water unit which is capable of achieving the independent humidity control and uses floor radiation to undertake an indoor sensible heat load, wherein refrigerant enters a condenser for condensing after being compressed in and discharged from a compressor, enters a reservoir after being condensed into liquid, is filtered via a filter, is out of the filter and enters a first evaporator after being throttled and decompressed via a first electronic expansion valve and changed into gas-liquid two-phase, and is performed with a heat exchange with chilled water in the first evaporator so as to absorb heat for evaporation and prepare high-temperature chilled water; the refrigerant is changed into overheating gas after being completely evaporated and enters into the compressor from a first suction end of the compressor, and is compressed and discharged once again; the refrigerant of the other path passes through a second electronic expansion valve, enters a second evaporator after being throttled and decompressed, is performed with the heat exchange with the chilled water in the second evaporator so as to absorb heat for evaporation and prepare low-temperature chilled water. In a circuit of the low-temperature chilled water, the chilled water is performed with the heat exchange with the refrigerant in the second evaporator to reduce the temperature.

Description
