Air conditioning device for effective and energy-saving evaporation refrigerating station

Abstract

The invention discloses an air conditioning device for an efficient and energy-saving evaporation refrigerating station. The air conditioning device is composed of an evaporation refrigerating coolingwater supply unit and a unit special for a fan room with multi-treatment surfaces in series and parallel, the structure of the evaporation refrigerating cooling water supply unit is that an exhaust chamber with an exhaust port is formed in the upper part of a crate, an exhaust fan is arranged on the exhaust port, a second air inlet is formed in the exhaust chamber, a spraying device, a filler anda water tank are arranged on the lower part of the exhaust chamber; the structure of the unit special for the fan room with the multi-treatment surfaces in series and parallel is that an air return chamber and an air supply chamber are arranged in the crate, the air return inlet is connected with the air return chamber, an air supply fan is arranged at the air supply inlet of the air supply chamber, and a second coil pipe and a first coil pipe or a direct evaporation refrigerating device are arranged in the air return chamber. According to the air conditioning device, the structure is reasonable, the outdoor natural cold source and dry air energy are utilized, the operation energy consumption of the cold source and the tail end is maximally lowered, the operation energy consumption of a whole data center machine room is lowered, and the air conditioning safety of the data center machine room is improved.

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
