High-efficiency energy-saving evaporative refrigeration machine room air conditioner

Abstract

The invention discloses a high-efficiency energy-saving evaporative refrigeration machine room air conditioner, which is composed of an evaporative cooling water supply unit and a multi-processing surface series-parallel outlet fan room special unit. The exhaust chamber of the outlet, the exhaust fan is arranged on the exhaust outlet, the second air inlet is arranged in the exhaust chamber, and the spray device, packing and water tank are arranged under the exhaust chamber; The chassis is equipped with a return air chamber and an air supply chamber. The return air inlet is connected to the return air chamber. The air supply port of the air supply chamber is equipped with a blower. The return air chamber is equipped with the second coil and the first coil or direct evaporation. refrigeration unit. The invention has a reasonable structure, utilizes the outdoor natural cooling source and dry air energy, maximizes the reduction of the operating energy consumption of the cooling source and the terminal, reduces the operating energy consumption of the entire data center computer room, and improves the air conditioning safety of the data center computer room.

Description

technical field [0001] The invention belongs to air treatment equipment in the field of heating, ventilating and air conditioning, in particular to an air conditioner for a high-efficiency energy-saving evaporative refrigeration machine room. Background technique [0002] In recent years, with the development of the IT information industry, more and more data centers of different sizes have been built all over the country. Due to the high heat density of the computer room, the heat generation per unit area of ​​the computer room has increased to 500-2000W / m2, and the power consumption of the air conditioning system for cooling the computer room accounts for 30% to 40% of the power consumption of the cabinets in the computer room. In order to reduce the power consumption of the computer room, a large number of large-scale data computer rooms serving the country have been built in the north. Among them, the power supply of a large computer room can reach 600,000 kW, which is e...

Problems solved by technology

[0004] Dry air energy evaporative cooling has also been used in data centers, but due to the large volume of the air handling device and the limitation of the computer room, it is difficult to install and maintain; in addition, the data center has very high requirements for the safe operation of the air conditioning system; dry air energy evaporation Refrigeration is greatly affected by the external air environment, and the temperature cannot be fully controlled when making cold air or cold water. In some time periods, it cannot meet the air supply requirements of the computer room, and the safe operation of the data computer room is the first consideration of the data center; therefore, based on the above Considering two points, the usual dry air energy evaporative cooling cannot meet the application of data center
