Research on Operation Characteristics and Control Strategy of High Efficiency Direct Expansion Air Conditioning Unit in Railway Station
This paper introduces the characteristics and operation control mode of the high-efficiency direct expansion air-conditioning refrigeration unit of the subway,and analyzes the operating electricity charge,equipment energy efficiency and system energy efficiency of the air-conditioning unit by comparing the real machine application of a station in Shenzhen subway with the screw unit station of similar specifications in the same station line.The results show that the high-efficiency direct expansion air conditioning unit has low operating cost and obvious energy saving and emission reduction effect.The real machine application of a certain iron station is compared with the screw unit station with similar specifications in the same station line,and the operating electricity charge,equipment energy efficiency,system energy efficiency and other aspects of the air conditioning unit are analyzed.The results show that the high-efficiency direct expansion air conditioning unit has low operating cost and obvious energy saving and emission reduction effect.
