Air conditioning system and control method

Abstract

The invention provides an air conditioning system and a control method.The air conditioning system comprises a fluorine pump, a compressor, a first evaporator, a second evaporator and an outdoor evaporative cooling system, the outdoor evaporative cooling system comprises an evaporative cooling device, a heat exchanger and a condenser, and the heat exchanger adopts cold water generated by the evaporative cooling device for heat exchange; the fluorine pump is sequentially connected with the first evaporator and the heat exchanger through pipelines to form a first circulation loop, the condenser is cooled through cold air generated by the evaporative cooling device, and the compressor is sequentially connected with the condenser, the throttling device and the second evaporator through pipelines to form a second circulation loop. Cold air and cold water generated by the evaporative cooling device are used for heat exchange, the condensation temperature of a compressor loop is reduced, and therefore the compressor power is reduced, meanwhile, due to the small heat transfer temperature difference of the water-cooling heat exchanger, the outdoor temperature corresponding to complete natural cooling of a fluorine pump is increased, and the power consumption of a compressor system and an air conditioner complete machine system is further reduced. And energy conservation is realized.

Description

technical field [0001] The invention relates to the technical field of infrastructure, and in particular, to an air conditioning system and a control method. Background technique [0002] With the rapid development of 5G, edge services will sink and corresponding edge data centers will appear in large numbers. In recent years, the edge business has mainly been sunk to the aggregation equipment room. Faced with this technical background, the development of air-conditioning hardware products suitable for the construction scenarios and needs of edge data centers / aggregation equipment rooms has become an urgent problem to be solved. [0003] However, the current parallel fluorine pump system has the following problems: [0004] (1) Both the compression refrigeration system and the fluorine pump refrigeration system only use half of the heat exchange area of ​​the evaporator and the condenser, half of the heat exchange area indoors and outdoors are wasted, and the utilization ra...

Problems solved by technology

[0004] (1) Both the compression refrigeration system and the fluorine pump refrigeration system use only half of the heat exchange area of ​​the evaporator and condenser, half of the heat exchange area is wasted indoors and outdoors, and the utilization rate of space and heat exchanger is low;

[0005] (2) The spray evaporative condenser on the outdoor side only uses the cold air source generated during the water evaporation process, and at the same time, there is a large heat transfer temperature difference between the refrigerant inside the air-cooled condenser and the outside air , generally around 10°C, so although the outside air temperature has dropped, the condensation temperature of the refrigerant inside the condenser is still high, and the energy saving is limited

[0006] Based on the above two problems of the existing technology, the system architecture of the existing technology fails to exert the optimal energy-saving effect
