Maintenance of evaporator1

After working for a period of time, the evaporator will form a frost layer on the coil, and even water, because the thermal conductivity system of frost (ice 1.9kcalmnhc) is much smaller than that of steel or copper. Frost on the evaporator coil will increase the heat transfer resistance, reduce the heat transfer effect, affect the cooling speed, increase the start-up time, and increase power consumption. Defrost in a timely manner according to the frosting condition of the evaporator. Due to the implementation of the new regulations [1], the smoke prevention zone can be expanded by approximately 2000 square meters. In parking garages smaller than 2000 square meters, the smoke exhaust duct can be used in conjunction with the exhaust duct.
