Abstract

The invention provides a high-efficient low-temperature evaporative cooling and heating system. A cooling medium water vapor pipe of a high-efficient low-temperature evaporative cooler is connected with a vacuum pipe of a jet vacuum apparatus via an output pipe; a water circulating output pipe of a heat collection water tank is connected with a water inlet pipe of the jet vacuum apparatus via a high-pressure hydraulic pump; a cooling medium water output pipe is disposed in the lower part of the high-efficient low-temperature evaporative cooler and disposed with a water transfer pump thereon; a cooling medium water return pipe is disposed in the upper part of the high-efficient low-temperature evaporative cooler; and a spraying device and fillers are disposed inside the high-efficient low-temperature evaporative cooler. During the process of transferring energy to the heat collection water tank and the energy receptor, heat source is utilized. The invention has the advantages of no influence by environmental temperature and humidity, sealed working medium, thermal insulation of equipment, closed system, and high and stable efficiency; and the absorbed heat can be accumulated to available heat energy in the heat collection water tank. The cooling medium water is directly cooled by phase change (large area evaporation under vacuum condition). The invention also has the advantages of low equipment production requirements, simple operation, less working procedures and low composite cost.

[0002] The traditional water-cooled compression refrigeration mode is: circulating water cooling tower→refrigerating compressor→refrigerant water→cooling capacity receptor, it is an open system, and the factor affecting its energy efficiency ratio is mainly the circulating water cooling tower, which is completely an open system, It is most sensitive to changes in ambient temperature and humidity. The higher the temperature and humidity, the greater the demand for cooling capacity and the lower the cooling efficiency

Specifically, in the process of energy transfer (cooling tower→compressor→fan coil group), the overall efficiency is low and the heat is dispersed.

The temperature and humidity around the cooling tower directly affect the system efficiency. This kind of open system cannot have stable efficiency, and the heat emitted by the cooling tower cannot be used.

After the phase change refrigeration of the working fluid, the process of transferring it to the refrigerant water through the heat exchanger is the compression of the working fluid→cooling and liquefaction→expansion refrigeration→heat exchange→refrigerant water, which requires high precision of manufacturing equipment, harsh manufacturing conditions, and many manufacturing processes. High production cost, high operating cost, complex structure, high maintenance cost
