A kind of multi-connected air conditioning system and operation control method

Abstract

The invention proposes a multi-connected air conditioning system and an operation control method. The multi-connected air conditioning system includes a fluorine pump circulation unit, an electric control unit, a compression refrigeration unit and a natural cooling unit for heat exchange with a refrigerant, and the electric control unit controls the compression refrigeration unit. Start-stop and adjustment of unit, natural cooling unit and fluorine pump circulation unit; compression refrigeration unit includes intermediate heat exchanger, compressor and condenser, intermediate heat exchanger, compressor and condenser are connected in series to form a loop; fluorine pump circulation unit It includes a gas pipeline, a liquid pipeline, a fluorine pump and a plurality of air-conditioning terminals, and the multiple air-conditioning terminals are arranged in parallel between the gas pipeline and the liquid pipeline; the fluorine pump is arranged on the liquid pipeline; the gas pipelines are respectively connected to One end of the intermediate heat exchanger and the natural cooling unit; the other ends of the intermediate heat exchanger and the natural cooling unit are respectively connected with the liquid pipeline. The multi-connected air conditioning system of the present invention reduces the number of outdoor units and has high heat dissipation efficiency.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a multi-connected air conditioner system and an operation control method. Background technique [0002] The data center computer room and base station computer room of the communication industry consume a lot of energy. About 40% of the power consumption is consumed by the air conditioning system to maintain a suitable working environment for communication equipment. In the 5G era, the power of communication equipment is higher, and the demand for air conditioning is higher. The energy consumption situation is further severe. It is necessary to use the natural cold source for free cooling as much as possible and reduce the energy consumption of air conditioners by using less compressors. [0003] At present, air-cooled air conditioners without natural cooling function are generally used in communication industry scenarios, and the energy consumption is relatively high. N...
