Computer room air conditioning system

Abstract

The invention belongs to the technical field of computer room air conditioners, and aims to solve the problems that the existing computer room air conditioner system cannot guarantee its normal operation in an ultra-low temperature environment and is not convenient for installation and arrangement of the computer room air conditioner system. For this reason, the present invention provides a kind of computer room air-conditioning system, and the computer room air-conditioning system comprises condenser, evaporator, compressor, liquid accumulator and electronic expansion valve, condenser, liquid accumulator, electronic expansion valve, evaporator and compressor Forming a closed-loop circulation main road, the computer room air conditioning system also includes a booster component, which can assist the compressor to increase the pressure of the refrigerant by connecting to the main circulation circuit, and replace the compressor when the computer room air conditioning system is in energy-saving operation. The invention enables the computer room air-conditioning system to work normally in an ultra-low temperature environment, and can increase the piping length of the computer room air-conditioning system to a certain extent and widen its height drop limit, so that the computer room air-conditioning system can meet the installation requirements of various building forms.

Description

technical field [0001] The invention belongs to the technical field of computer room air conditioners, and specifically provides a computer room air conditioner system. Background technique [0002] With the rapid development of the Internet economy, many network electronic computer rooms have been built. The electronic equipment in the computer room runs all year round and emits a lot of heat. Accordingly, the computer room air-conditioning system is required to cool down the electronic equipment in the electronic computer room, that is, the computer room air-conditioning system needs to be cooled and operated throughout the year. When the outdoor temperature is low in winter, the air-conditioning system of the computer room often has failures such as low condensation pressure and alarms during cooling operation, which makes the unit unable to operate normally. In order to ensure the normal cooling requirements of electronic equipment in the computer room, very strict requ...
