Abstract

The invention discloses a precision heat exchange system of an air-cooling split-type water cooler. A heat exchanger (evaporator) for heat exchange with external air (atmosphere) is additionally arranged in the heat exchange system. When a first controlled circulation liquid heat load is smaller than a refrigerating machine refrigerating capacity, the system uses remaining refrigerating capacity partially for heat exchange with the external air (for conducting refrigeration on the external air), so that continuous high-precision temperature control over first controlled circulation liquid is facilitated, the production cost is saved, and production efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the field of heat exchange, in particular to an air-cooled split-type water chiller precision heat exchange system. 【Background technique】 [0002] 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. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a precision heat exchange system for an air-cooled split chiller to solve the problem that t...
