Abstract：To evaluate the energy efficiency level of the direct expansion unit and its refrigeration system in the hot summer and warm winter area,an on-site test is conducted on the magnetic levitation direct expansion air conditioning system of a metro station in Foshan City located in the hot summer and warm winter area.The results show that under typical working conditions,the measured energy efficiency of the magnetic levitation direct expansion refrigeration system of this station reaches 6.1,which is significantly improved compared with the common level in China.Therefore,it is preliminarily judged that the magnetic levitation direct expansion air conditioning system has a better application effect in areas with hot summers and warm winters.
