NH3CO2 Stacking block unit

Product Introduction

System advantages:

1、 Low carbon and environmental protection: The stacked pry block is mainly composed of low-temperature and high-temperature stages. The low-temperature stage uses natural and environmentally friendly working fluid CO2 as the refrigerant, while the high-temperature stage uses natural and environmentally friendly working fluid NH3 as the refrigerant. NH3 has an ODP of 0 and a GWP of 0; The ODP of CO2 is 0, GWP is 1, meeting the requirements of low-carbon environmental protection.

Energy saving operation: The stacked pry block is suitable for various working conditions with evaporation temperatures between -50~-25 ℃. Under quick freezing conditions, the evaporation temperature is lower, the quick freezing effect is better, and the operating energy consumption is slightly lower than that of NH3 in a dual machine two-stage system, which is particularly suitable for large and medium-sized quick freezing systems.

3、 Safe and stable: Low temperature natural working fluid CO2 has the characteristics of safety, non toxicity, and non flammability, and can be used in densely populated places such as warehouses and production areas. It is harmless to personnel and does not pollute food. High temperature natural working fluid NH3 is only used in the computer room with a small filling amount, avoiding direct contact with workshop personnel and food, and ensuring effective operational safety.

4、 Low refrigerant charge: The condenser and cascade heat exchanger adopt a plate and shell type, with the heat exchanger being a plate and the external being a pressure bearing shell. While improving heat transfer efficiency, further reducing the amount of NH3 injection is safer.

5、 Efficient oil separation: Equipped with a high-efficiency horizontal oil separator developed by DASEN, it achieves an oil separation effect of 10ppm, reduces the flow of lubricating oil into the end heat exchanger, and improves heat transfer efficiency.
