(Summary description)2. Assembly and installation of refrigeration unit

1. The semi-hermetic or hermetic compressor should be equipped with an oil separator, and an appropriate amount of oil should be added to the oil. When the evaporation temperature is lower than minus 15 degrees, a gas-liquid separator and an appropriate amount of refrigerating oil should be installed.

2. The base of the cold storage compressor should be equipped with a shock-absorbing rubber seat.

3. The installation of the unit should leave a maintenance space to facilitate the observation of the adjustment of the instrument and the valve

4. The high-pressure meter for cold storage installation should be installed at the three-way point of the liquid storage irrigation valve.

Information

1. Cold storage installation and air cooler installation

1. When choosing the position of the lifting point for cold storage installation, first consider the position with better air circulation, and consider the structural direction of the storage body.

2. The clearance between the air cooler and the library board should be greater than the thickness of the air cooler.

3. All hanging bolts of the air cooler should be fastened, and the bolts and hanging bolt perforations should be sealed with sealant to prevent cold bridges and air leakage

4. When the ceiling fan is too heavy, use No. 4 or No. 5 angle iron as the lintel. The lintel should span to another roof and wall to reduce the load.

What kind of pre-cooling treatment should be done before the goods enter the cold storage?

The so-called pre-cooling mainly refers to a process in which various types of goods, such as food, can be stored in the cold storage from room temperature to 0°C, or close to the temperature of the storage cold storage. In this process, the rapid cooling process before cooling or rapid freezing is called pre-cooling.

Cold storage insulation materials and moisture-proof materials

Insulation materials for cold storage should meet the following conditions: 1. The thermal conductivity is small, so that a thinner thermal insulation layer can be used to obtain a better thermal insulation effect. 2. Low density and low price. 3. Good moisture resistance, frost resistance, firmness, high compressive strength, and durability to ensure long-term use. 4. Well thought out fire resistance, unnatural, and not supporting combustion, so as to improve the fireproof performance of the cold storage. 5. It does not produce any peculiar smell, does not absorb peculiar smell, and does not emit toxic substances, which is of great significance to food storage in cold storage. In addition, the cold storage insulation material should also have good corrosion resistance and not breed worms or other bacteria.

What is the reason for the power consumption of the cold storage? How to reduce electricity consumption in cold storage

1. First, let's take an example of food cold storage to analyze what factors will cause the increase in power consumption of cold storage: 1. Incorrect design of food cold storage-the design of the refrigerant connection pipe is too long, the cooling configuration of the unit does not meet the requirements, the thickness of the plate does not meet the standard, the low-temperature cold storage does not use aluminum row type, the external machine does not match the internal machine, and the cold storage adopts Conditions such as 220v electricity will increase power consumption. 2. Incorrect use of food cold storage-the goods are not pre-cooled before entering the storage with their own temperature, frequently entering and leaving the cold storage without opening the door without installing the air curtain, unreasonable stacking of incoming and outgoing goods, and irregular maintenance of the cold storage, etc. It will also lead to increased power consumption in cold storage.
