Product Description
1.NH3/CO2, the principle of cascade refrigeration system
NH3/CO2, the cascade refrigeration system is composed of two parts: high temperature stage and low temperature stage, the high temperature stage uses NH3 as the refrigerant, and the low temperature stage uses CO2 as the refrigerant. The evaporation of refrigerant NH3 in the high temperature level system is used to condense the refrigerant gas CO2 discharged from the low temperature level. A condensation evaporator is used to connect the two parts of the high and low temperature levels, which is both the condenser of the low temperature level and the evaporator of the high temperature level.
(1) Reduced NH3 unsafe factors:
(1.(1))NH3/CO2 cascade refrigeration system greatly reduces the condensing pressure of the NH3 refrigeration medium charge, about 1/10 of the traditional ammonia refrigeration system charge;
(1.(2))NH3 is limited to the machine room, equipment room, equivalent to the "tiger" in the "cage ", guarded by professional and technical personnel;
(1.(3))full use of NH3 in the high-temperature region of the good heat transfer properties, used to cool CO2.
(2) CO2 as a medium into the personnel-intensive operation room (such as single-freezing machine) and the warehouse, to ensure the safety of personnel and property.
3) CO2 is applied as a low-temperature grade work medium. Not only can it overcome the shortcomings of its high pressure, but also make full use of the advantages of CO2's high heat transfer efficiency in low-temperature conditions.
