Machine room air conditioner

Abstract

The invention discloses a machine room air conditioner, which comprises a shell, an evaporator and a compressor which are arranged in the shell, and an isenthalpic humidifier and a water mist guide pipe which are arranged in the shell. A bypass air duct is arranged between one side of the evaporator and the side wall of the shell. One end of the water mist guide pipe is connected with the isenthalpic humidifier and the water mist guide pipe is used for guiding water mist produced by the isenthalpic humidifier into the bypass air duct. The other end of the water mist guide pipe is connected with an outlet pipeline piece. The outlet pipeline piece is used for spraying out the water mist in the water mist guide pipe. The sprayed water mist is used for humidifying air in the bypass air duct. An air valve is arranged at the inlet end of the bypass air duct and is used for controlling air quantity of the bypass air duct. The humidified air in the bypass air duct is exhausted from the outlet end of the bypass air duct. The machine room air conditioner has the advantages that the energy consumption for humidification of the machine room air conditioner can be reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a computer room air conditioner. Background technique [0002] The data computer room needs an external environment with constant temperature and humidity to ensure the reliability of data transmission in the computer room. At present, computer rooms are generally equipped with precision air conditioners. With the rapid development of data computer rooms, the demand for precision air conditioners has also become a rapid growth trend. [0003] The heat generated by the equipment in the data center is very large, and the average energy consumption of precision air conditioners accounts for 30%-40% of the total power consumption of the equipment in the entire computer room. Therefore, how to minimize the energy consumption of air conditioners while ensuring the ambient temperature and humidity of the computer room Become the key to energy saving in the computer room.

AI Technical Summary

Problems solved by technology

[0005] Theoretically, the humidification capacity of 1kg / h consumes more than 650W. For a precision air conditioner of 100kW, based on the humidification capacity of 10kg / h, at least 6.5kWh of power consumption is required. The energy consumption of the humidifier in this precision air conditioner accounts for 10% of the total energy consumption. More than 15%, the actual energy efficiency is very low, which does not meet the current development trend of energy saving in computer rooms
