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

technical field [0001] The invention relates to a water chiller capable of independent treatment of heat and humidity, which uses floor radiation to bear indoor sensible heat load, and an auxiliary fan coil unit to bear indoor humidity load, and an air treatment method thereof, which belongs to the technical field of design and manufacture of refrigeration and air-conditioning systems. Background technique [0002] With the improvement of people's living standards, the requirements for the comfort of work, study and living environment are getting higher and higher, and air conditioners are widely used. However, with the depletion of fossil energy, energy shortage has become an important problem facing the development of the world , How to achieve energy saving on the basis of meeting people's comfort needs is very important. The floor radiant cooling technology has such characteristics. The floor radiant cooling has the advantages of high comfort and energy saving. However, ...
