Why just open the freezer temperature drop slowly?

on the market at present, non-professional refrigeration equipment manufacturers, product quality is uneven, in order to reduce costs, compressor power, evaporator gold area may not be able to meet the requirements, such as insulation and thermal insulation layer can only replace with foam, heat preservation sex declines, leak air conditioning will be very serious, air-conditioner temperature does not drop, or cooling effect will be a long time. So choose regular is the precondition for the purchase of air-conditioner refrigeration equipment manufacturers. 1, the regular of air-conditioner, refrigeration equipment manufacturers, first check the cooler temperature set up correctly, if the temperature to adjust itself is not low, the temperature will not automatically fall. Open the freezer temperature is too high, the process of cooling time also need to lengthen. 2, lack of refrigerant is one of the important reasons of air-conditioner can't refrigeration, work for a few years later, there will be a shortage of refrigerants, simply add a sufficient number of refrigerants. If there is refrigerant leakage, the first to find leak, check all pipe, valves, joints, find leakage part, modify, and adequate refrigerant. 3, improper adjustment throttle valve or cut off the throttle, or refrigerant flow is too big or too small, will directly affect the flow of refrigerant entering the evaporator. Throttle opening, the refrigerant flow rate is increased, the evaporation pressure and evaporation temperature, the cooler temperature drops at a slower pace. 4, the appearance of the air-conditioner evaporator if frost too thick or too much dust, will reduce heat transfer effect. Evaporator appearance frost too thick or too much dust, low power of heat transfer in the evaporator, lead to library temperature slow down another important reason is the low power of heat transfer in the evaporator. If dust too much or the cooler condenser on the wall, the poor thermal cooling, cooling effect is the important reasons for the deteriorating of the possible, especially in the summer, the effect is particularly obvious, so keep the commercial freezer around well ventilated, maintain clean, dust-free, condenser is freezer cooling fast. Why just open the freezer temperature drop slowly insulation and insulation effect may be bad, mainly choose the wrong when the design of insulation layer thickness, or construction insulation material quality is not good. In addition, in the process of construction, insulation moisture resistance of thermal barrier was damaged, the thermal barrier will happen, deformation, corrosion, moisture loss of insulation, refrigeration capacity fell, the cold mass loss increases, the temperature drop has slowed sharply. Cooling loss of another important reason is that the sealing performance is bad, from leaking into the more hot air. Generally speaking, if appear in the Windows and doors seal or freezer insulation sealing phenomenon, then seal is not strict. In addition, often close the door or a lot of people together into the warehouse, cold mass loss will increase. Don't open the door, in order to avoid the hot air in as much as possible.
