Cold storage characteristics and classification of refrigerants

when wants to build a refrigerator, we generally pay close attention to more is some needed to build the cold storage equipment, materials, such as cold storage board, air cooler, condenser, etc. Because you know only choose good quality equipment, material will build the high quality cold storage. Built cold storage, however, need to know some equipment and materials, you should also know that cold storage built after we should use what kind of refrigerant, for use which kinds of refrigerant. This requests us to some refrigerants have a certain understanding, let's know the kinds of several kinds of refrigerants and code.

1。 Saturated hydrocarbon refrigerants

saturated carbon nitrogen compound naming also according to the naming of freon refrigerant,. Such as: methane as the R50, ethane as

R170, but R600 butane writing.

2。 Unsaturated hydrocarbon refrigerants

unsaturated hydrocarbon refrigerants and halogen derivative refrigerant naming is written at the back of the R first write a '1',

then write by freon naming rules. Such as two chlorine two fluorine ethane as RI 112 a and tetrafluoroethylene as R1114.

3。 Azeotropic mixture refrigerant

azeotropic mixture refrigerant is composed of two or more than two mutually soluble single-component refrigerant at room temperature in a certain mass ratio and volume than mutual mixture refrigerants. Azeotropic mixture refrigerants have a boiling point, at this point, the vapor composition is the same as the solution composition, under certain pressure, the liquid evaporation into gas when boiling temperature does not change.

have commercialized azeotropic mixture refrigerants naming is in '500' serial number according to provisions of the order of the development of its identification number. Such as R500, R501, r114, etc.

4 in high temperature and moderate temperature refrigerant

high temperature refrigerant is mainly used for air conditioning refrigerating unit and heat pump unit, the temperature in the refrigerant used in general single stage and

two stage compression type refrigerant, while low temperature refrigerant used in cascade type low temperature part of the refrigerant.
