Air-cooling thermotube-type machine room air-conditioning system

Abstract

The invention discloses an air-cooling thermotube-type machine room air-conditioning system which comprises a compressor, a first air cooling condenser, a throttling set, an evaporative condenser, a liquid storage tank, a flow balance valve, a tail end heat exchanger, a bubble pump, a first refrigerant changeover valve, a second refrigerant changeover valve and a second air cooling condenser, wherein the high-pressure exhaust port of the compressor is orderly connected with the first air cooling condenser, the throttling set, the evaporation side of the evaporative condenser, and the low-pressure air suction inlet of the compressor, thereby forming a compression refrigerating cycle loop; the condensing side outlet of the evaporative condenser is orderly connected with the liquid storage tank, the flow balance valve, the tail end heat exchanger, the bubble pump, the first refrigerant changeover valve, and the condensing side inlet of the evaporative condenser; and the outlet of the tail end heat exchanger is orderly connected with the second refrigerant changeover valve, the second air cooling condenser, and the inlet of the liquid storage tank, thereby forming a thermotube refrigerating cycle loop. The system has the advantages of small temperature difference and high energy efficiency ratio during heat exchange.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an air-cooled heat pipe type computer room air conditioning system. Background technique [0002] With the rapid development of my country's information industry and network applications in recent years, the construction speed of computer rooms and base stations has been greatly accelerated, and their number has increased rapidly, becoming more and more energy-consuming. According to statistics, the energy consumption of computer rooms and base stations accounts for 90% of the energy consumption of the entire network, and the energy consumption of air conditioning and cooling accounts for 40% to 50% of the energy consumption of computer rooms and base stations. In particular, many base stations still need to use air conditioners for cooling in spring and autumn and winter, when the outdoor air temperature is often relatively low. If the outdoor low temperature ca...

Problems solved by technology

[0006] However, the cooling method of the existing fresh air system will have more complicated air quality processing problems, and the cooling system of the heat exchange method will have the problems of large operating temperature difference and low energy efficiency ratio
