Abstract

The invention discloses a precision heat exchange system for an ice water machine with an integrated structure of an air condenser and an evaporator. In the system, an additional heat exchanger (evaporator) with the external air (atmosphere) is added. When the heat load of the first circulating liquid is controlled When it is less than the cooling capacity of the refrigerator, the system uses the remaining cooling capacity for heat exchange with the outside air (cooling the outside air), thus facilitating the continuous high-precision temperature control of the controlled first circulating fluid, saving production costs and improving production efficiency.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of heat exchange, in particular to a precision heat exchange system for an ice water machine with an integrated structure of an air condenser and an evaporator. [0003] 【Background technique】 [0004] In industrial production, air-cooled water chillers usually use compressor ON / OFF or heat medium bypass using refrigerant (freon) to control the temperature of the circulating liquid. Due to the limitation of mechanical performance, the ON / OFF switching period of the refrigerator is long, which cannot meet the requirements of high temperature control accuracy of the circulating liquid (such as ±0.5°C, ±0.1°C, ±0.01°C, etc.), and the heat medium Bypass will affect the pressure stability of the refrigerant (freon), thereby affecting the high-precision temperature control requirements. [0005] 【Content of invention】 [0006] The technical problem to be solved by the present invention is to provide a precision he...
