Plate Heat Exchanger in Refrigeration

 Cold storage refrigeration introduction

According to the type of refrigerant, the refrigerant circulation system can be classified into an ammonia refrigeration system and a fluorine refrigeration system.

The heat exchange equipment used in the cooling room, freezing room, refrigerating room, cold storage room, ice making room and ice storage is: cooler, waste heat exchanger, shell-and-tube water heat exchanger, evaporator, condenser and so on.

The temperature in the cooling compartment is generally maintained at 0-2°C.

According to temperature,assembled cold storage can be divided into:

1) L-level preservation library. Mainly used for storing fruits and vegetables, eggs, medicinal materials, fresh-keeping and drying; the temperature of the food into the warehouse is +30 °C; the temperature of the cold storage is generally +5 ~ -5°C.

2) Class D refrigerator. It is mainly used for storing meat, aquatic products and products suitable for this temperature range; the temperature of the food into the warehouse is +15°C, and the temperature of the cold storage is generally -5 to -20°C.

3) Class J low temperature library. Mainly used for storing ice cream, ice cream, low-temperature food and medical supplies; the temperature of the food into the warehouse is +15°C, and the temperature of the cold storage is generally -25°C.
