Problems solved by technology

However, the method of increasing the heat exchange area of ​​the condenser takes up a lot of space, the economy is not good, and it is impossible to accurately control the degree of subcooling
[0004] For high-power units, it is necessary to cool the lubricating oil to prevent the temperature of the lubricating oil from being too high and the viscosity to drop, resulting in poor lubrication of the compres

Abstract

The invention discloses a water chilling unit provided with a super-cooler and a lubricating oil cooler. A main loop of the water chilling unit is sequentially connected with a compressor module, an oil separator, a condenser, the super-cooler, a liquid storing machine, a thermal expansion valve, an evaporator, an air and liquid separator and the like. A first bypass and a second bypass are correspondingly arranged in parallel between the outlet of the liquid storing machine and the outlet of the evaporator; super-cooling of condensate of a refrigerant and cooling of lubricating oil are realized; the evaporation temperature of the water chilling unit and the oil supply temperature of a compressor are precisely controlled; the lubrication performance of the compressor of key equipment is improved; and the environmental suitability and reliability of the water chilling unit are improved.
