Cold room cooling methords

The cold storage refrigeration methods mainly include the following:

  1 Cold room evaporative refrigeration Heat is absorbed by evaporation of refrigerants such as freon, reducing the indoor temperature. This method is energy-saving, but it requires high-pressure and high-temperature refrigerant, which has a certain pollution to the environment. Compression refrigeration The refrigerant is compressed and cooled by a compressor and cooled by a condenser. This method has mature technology and stable cooling effect, but low energy efficiency and high operating costs.

  Absorption refrigeration Refrigeration is achieved by the absorption between the refrigerant and the absorbent. This method saves electricity and is environmentally friendly, but the refrigeration effect is average.

  Water evaporative refrigeration Water evaporation takes away heat to achieve energy saving and cooling. It is suitable for scenarios that require energy saving without compromising the quality of stored materials. Electronic refrigeration is Based on the Peltier effect, cooling is achieved by heating and cooling. It is suitable for fanless and noiseless environments, but the cooling technology is still evolving.

  Liquid nitrogen refrigeration It is suitable for large-scale cold storage, with low price and low power consumption, but there are safety and environmental protection problems, and it is not recommended by the state at present.

  Freon refrigeration technical threshold is low, and it is suitable for large, medium and small cold storage, but the power consumption is high. Carbon dioxide liquid ammonia refrigeration Safe and environmentally friendly, mature technology, suitable for large-scale cold storage, but the price is higher.

  Each refrigeration method has its advantages and disadvantages, and the choice should be based on the scale of the cold storage, budget, environmental protection requirements and other factors.
