Why is the temperature of the supermarket refrigeration equipment continuously rising, making it difficult or extremely slow to cool down? Let's take the supermarket refrigerator as an example and analyze the reasons.

The unique characteristics of supermarket refrigerators result in the inability to ensure their thermal insulation and sealing properties. This necessitates more cold air to maintain cooling, thereby increasing power consumption. The primary reason for poor thermal insulation in supermarket refrigerators is due to the insufficient thickness of the thermal insulation layer in the refrigerator pipes and the separating panels between the refrigerator and the external environment, which do not meet the required thickness. This insufficient thickness reduces the refrigerator's thermal insulation effectiveness. This situation arises from two reasons: either the thickness of the insulation board was not selected adequately or the quality of the material used was not ideal. This has compromised the moisture-proof properties of the thermal insulation material, leading to a decrease in sealing performance and an increase in the energy consumption for refrigeration.

The frost or dust on the evaporator surface is excessive, reducing the heat transfer efficiency and increasing the rate of temperature drop. Generally, the evaporator surface temperature of supermarket refrigerators is below 0°C. In high humidity conditions, moisture in the air can easily form frost on the evaporator surface of supermarket refrigeration equipment, and some may even freeze directly, lowering the overall heat transfer efficiency of the evaporator. Therefore, it is usually necessary to regularly clean the frost on the evaporator surface of refrigeration equipment to enhance the refrigeration efficiency of the evaporator and reduce energy consumption.

Here are just two of the reasons; more will be shared with you in the coming days. We hope the cooling equipment temperature-sharing from Xiamen Xin San Yang Industrial Co., Ltd. proves helpful to you.
