NISSIN has been making contributions with the leading-edge technologies to a wide range of industries, including shipping, ice making and refrigerating warehouse, building air-conditioners, and special air-conditioners.

Main characteristics of HFC refrigerant (For comparison, R22, R717, and R744 are also shown.)

Main usage of HFC refrigerant

Characteristics of HFC refrigerant

Design pressure of refrigerant

[1] KHK design pressure

*The design pressure of high-pressure sections and low-pressure sections should desirably be the saturation pressure (gas-liquid equilibrium pressure of non-azeotropic mixed refrigerant gas) that corresponds to the temperature shown in the table. However, if medium temperature is used, a pressure value in table should be interpolated.
