This paper analyzes the reason of the air-conditioner cooling slowly

freezers - price Analysis of air-conditioner in the cause of the slow cooling in many daily mall, in the process of using commercial freezers, many businesses will find that such a problem, is the encounter of air-conditioner temperature is difficult to cut down the temperature of the situation, for this kind of situation, the snow freezers combined with practical experience, summed up the following reasons for everybody to learn. 1, human factors of temperature and check his temperature is appropriate, if the temperature is not low, then the temperature will not automatically fall. 2, environmental temperature factors. May be the cause of the environmental temperature, the temperature in the summer of too high, so the temperature of the commercial freezer for a will drop down. Three factors, frost and water tank. Check whether there is at the back of the commercial freezer to sink, frost water not directly into to sink in, and cause freezer with water. If you have this kind of phenomenon, can cushion the front a little higher, so you can BaoZhengHua frost water flows smoothly into the sink. 4, throttle valve and refrigerant flow factor. Throttle valve regulating improper or blocked, will directly affect the flow of refrigerant into the evaporator. When the throttle valve open through large, refrigerant flow slants big, evaporating pressure and evaporation temperature is elevated, incase temperature lower speed will slow. 5, refrigeration dose of factors. Lack of refrigeration dose of refrigeration system, cooling effect is affected. Lack of refrigerant circulation first, there are two reasons, one is the lack of refrigerant filling quantity, at the moment, just add plenty of refrigerants. Another reason is that the system refrigerant leakage is more, in this situation, you should find funnelled, key points of view at all pipe, valves, connecting, find out leakage parts after repair, and filling the full amount of refrigerant. Six factors, compressor. The compressor power is low, the capacity can't meet load requirements contained in the cabinet. Inferior compressor because of long time work, sealing function will reduce accordingly, decreases in the coefficient of the gas compressor refrigerating capacity will be reduced. 7, air-conditioner heat insulation and the function of sealing. Freezers due to poor insulation or sealing function, cause a large cooling capacity loss. Because of poor heat insulation function pipe, insulating wall ark of insulation layer thickness is not enough, poor heat insulation and heat preservation effect. Eight factors, evaporator. 1. The appearance of air-conditioner evaporator frosting too thick or too much dust, heat transfer effect is reduced, results in the decrease of temperature inside ark is slow. 2. Transpiration is the heat transfer tube appearance with more frozen oil, its heat transfer coefficient will decrease, the same, if there is more air in the pipe, the evaporator of heat exchange area is reduced, the heat transfer power will be significantly reduced, incase temperature lowering speed is slow.
