The invention provides an air conditioning system and a control method of the air conditioning system. The air conditioning system comprises a liquid pump pipeline and a compressor pipeline, wherein the compressor pipeline is provided with a compressor, a condenser, an expansion valve and an evaporator which sequentially communicate with one another in a closed-loop mode in the refrigerant flowingdirection. The liquid pump pipeline comprises a first pipeline and a second pipeline, one end of the first pipeline communicates with a pipeline between the evaporator and the expansion valve, and the other end of the first pipeline communicates with a pipeline between the condenser and the expansion valve. The first pipeline comprises a liquid pump and a liquid storage tank located between the liquid pump and the condenser. Two ends of the second pipeline communicate with the second end of the evaporator and the first end of the condenser respectively so that the compressor can be short-circuited when the liquid pump pipeline works. When the compressor pipeline works, an inlet of the liquid storage tank is controlled to be connected with the compressor pipeline, redundant refrigerants inthe compressor pipeline enter the liquid storage tank, and therefore, the problems that in a composite air conditioning system in the prior art, due to the fact that the requirements of the compressor pipeline and the liquid pump pipeline for the circulation amount of refrigerants are different, redundant liquid refrigerants exist in the air conditioning system are solved.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system and a control method for the air conditioning system. Background technique [0002] The modern Internet big data industry is developing rapidly. As the scale of the data center gradually increases, the calculation speed gradually accelerates, and the heating power of IT equipment also gradually increases. Therefore, the load of the air conditioner in the computer room increases, and its energy consumption is equal to the total energy consumption of the data center. than nearly 35%. [0003] In order to reduce the energy consumption of the air conditioner in the data center computer room, in the prior art, a liquid pump is used instead of the compressor to drive the refrigerant cycle in the air conditioning system in winter. Heat, in order to achieve the effect of reducing the indoor temperature. In addition, since the liquid pump driv...
