Abstract

The invention discloses a composite evaporative cooling device with a natural cooling function for large-scale equipment. The composite evaporative cooling device comprises a refrigeration compressor (1), a condenser (2), a dry filter (3), a refrigerant liquid pipeline electromagnetic valve (4), an expansion valve (5), a gas-liquid separation recooler (7), a refrigerant circulating pump (8) and a three-way adjusting valve (12), wherein the gas-liquid recooler (7) is communicated with the refrigeration compressor (1) and the condenser (2) as well as external natural cold sources. By adopting Freon as liquid refrigerant, the state of the refrigerant is changed by steam compressing and refrigerating circulation or natural cooling circulation, work efficiency of a refrigerating device is improved, energy is saved, consumption is reduced, and operation range of natural cooling and refrigerating is expanded. The composite evaporative cooling device is simple in structure and convenient to use, safety of the large-scale equipment is improved and electricity consumption can be saved by more than 20%.

Description

technical field [0001] The present invention relates to the cooling of large-scale equipment in industrial fields such as computer equipment, data center, petrochemical industry, food and pharmacy, etc., in particular to a compound evaporative cooling device with natural cooling function for large-scale equipment using liquid cooling . Background technique [0002] In modern large-scale computer centers and data centers, since electrical energy will eventually be converted into heat energy during data processing, if this part of heat energy cannot be eliminated in time, the temperature of computer equipment will be too high, resulting in reduced computer operating speed and failure rate. increase, or even downtime failures and loss of key data. Therefore, all large-scale computer centers and data centers need a special refrigeration device to provide 24-hour uninterrupted cooling service for computer equipment throughout the year to ensure reliable operation of computer equ...
