1. The thickness of thermal insulation precast slab is lack of corresponding serialization: for the assembled cold storage sold in the market at present, the manufacturer adopts polyurethane thermal insulation precast slab with a thickness of 100 mm regardless of the warehouse temperature requirements, which will correspondingly cause many problems such as insufficient thermal insulation capacity of the cold storage body, serious cooling consumption and so on. In this regard, we can see from the analysis of the above empirical formula for calculating the thickness of the insulation precast slab that the thickness (δ) of the insulation layer of the cold storage is proportional to the temperature difference between the inside and outside of the cold storage itself (tw tn). According to the setting requirements of the temperature in the cold storage, if the thickness of the insulation layer can reach the design index, the thermal insulation performance of the cold storage is good, and the outside

In summer, the power load of high temperature society is large, and sudden power failure may occur in some areas. After the power is cut off, the refrigeration equipment of the cold storage will stop working, resulting in temperature rise in the cold storage, poor air circulation, deterioration of refrigerated goods and economic losses for a long time. What should we do if the cold storage is suddenly cut off during operation? Shenzhen Refrigeration Engineering Co., Ltd. - Bingyuan Refrigeration Co., Ltd. 1. The cold storage is equipped with standby power supply. If the refrigerated goods in the cold storage are expensive or vulnerable to temperature changes, the cold storage can be equipped with standby power supply to ensure that the refrigeration equipment in the cold storage can be supported for a short time after power failure. Large cold storage

Freon is generally used as refrigerant in cold storage. 1. The main engine is a semi closed piston engine of Bezel; 2. The condenser can be the shell type condenser of water-cooled condensing unit, and the cooling tower can be used; 3. If the evaporator is simpler, the air cooler can be used. It is mainly selected according to the temperature of your cold storage and the heat exchange area. 4. System pipes (copper pipes, seamless steel pipes). Water system pipes (PVC pipes are OK). 5. Valves (generally around 3000), including solenoid valves, expansion valves, filters, etc; 6. The electric control device (including electric control cabinet, sensor, temperature control, etc.) needs about 5000; 7. Make

Some suggestions for acceptance of cold storage Usually, before building the cold storage, the householder will discuss with the cold storage engineering construction about the cold storage design scheme, the requirements for the construction of safe cold storage, the construction period of the cold storage, and the payment method of the cold storage. However, many people are afraid of acceptance after the completion of the cold storage project. As the contractor and user, they should prepare for acceptance in time after the completion of the cold storage project. Here are some considerations and suggestions for cold storage acceptance. During the acceptance, we should pay attention to the following items: 1. Appearance acceptance of the cold storage body: whether the installation of the cold storage body is coordinated, whether the connection between the storage plate and the storage plate is tight, and whether the cold storage door is installed
