Water-cooled energy-saving machine room air conditioning system

Abstract

The invention discloses a water-cooled energy-saving machine room air conditioning system, which comprises a compressor, a water-cooled condenser, a throttling device, an evaporative cooling condenser, a liquid storage tank, a coolant pump, a flow balancing valve, a terminal heat exchanger, a cooling tower, a cooling water pump, a first water outlet valve, a first water inlet valve, a first drain valve, a second water inlet valve, a second water outlet valve and a second drain valve; the high-pressure exhaust port of the compressor is connected with the refrigerant side of the water-cooled condenser, the throttling device, the evaporation side of the evaporative cooling condenser and the low-pressure air suction port of the compressor in turn to form a compressed refrigerating circulation loop together with a cooing water circulation loop; and the condensation side outlet of the evaporative cooling condenser is connected with the liquid storage tank, the coolant pump, the flow balancing valve, the terminal heat exchanger and the condensation side inlet of the evaporative cooling condenser in turn to form a nearly isobaric evaporation and condensation refrigerating circulation loop together with a cooling water circulation loop. During heat exchange, the system has low temperature difference and high energy efficiency ratio.

Description

technical field

[0001] The invention relates to the technical field of air-conditioning systems, in particular to a water-cooled energy-saving air-conditioning system for a computer room. 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 temperat...
