Multi-connected air conditioning system and operation control method

Abstract

The invention provides a multi-connected air conditioning system and an operation control method. The multi-connected air conditioning system comprises a fluorine pump circulation unit, an electric control unit, a compression refrigeration unit and a natural cooling unit, wherein the compression refrigeration unit and the natural cooling unit exchange heat with a refrigerant, the electric control unit controls the start, the stop and the adjustment of the compression refrigeration unit, the natural cooling unit and the fluorine pump circulation unit; the compression refrigeration unit comprises an intermediate heat exchanger, a compressor and a condenser which are sequentially connected in series to form a loop; the fluorine pump circulating unit comprises a gas pipeline, a liquid pipeline, a fluorine pump and a plurality of air conditioning terminals, and the air conditioning terminals are arranged between the gas pipeline and the liquid pipeline in parallel; the fluorine pump is arranged on the liquid pipeline; the gas pipeline is respectively connected to one end of the intermediate heat exchanger and one end of the natural cooling unit; and the other ends of the intermediate heat exchanger and the natural cooling unit are respectively connected with the liquid pipeline. According to the multi-connected air conditioning system, the number of outdoor units is reduced, and the heat dissipation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a multi-connected air conditioning system and an operation control method. Background technique [0002] The data center computer room and base station computer room in the communication industry consume a lot of energy, and about 40% of the power consumption is consumed by the air conditioning system, which is used 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 greater. Larger, the energy consumption situation is further severe, it is necessary to use natural cooling sources 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 the communication industry scene, which consumes a l...
