Detailed description of the invention
The one that the present invention provides for the ternary refrigerant of-50 DEG C ~-60 DEG C of cryogenic temperatures, in parts by weight by with
Lower component forms: 45 ~ 75 parts of propane (R290);50 ~ 20 parts of ethane (R170);Tetrafluoroethane (R134a) 5 parts.
Specifically, the present invention for-50 DEG C ~-60 DEG C of cryogenic temperatures ternary refrigerant use quasi-boiling temperature be-
The low boiling point refrigerant R170 of 88.58 DEG C, to meet the refrigeration requirement of low temperature-60 DEG C, and in order to meet employing one-stage steam
The use requirement of contraction SAPMAC method, is respectively the R290 of-42 DEG C and the R134a of-26 DEG C by hybrid standard boiling temperature, reduces
The pressure ratio of refrigeration system compressor both sides and pressure reduction, make refrigeration system high pressure in the range of 2 ~ 2.5MPa, it is adaptable to existing business
With piston compressor, instead of what conventionally employed kind of refrigeration cycle optimization (multi-stage compression or Auto-cascade cycle or multistage overlapping) could realize
Low temperature stores.Wherein, the refrigeration requirement of different temperatures can be met by the ternary refrigerant of differently configured weight portion, such as:
Realize the cold-producing medium proportioning of about-50 DEG C storage temperature: propane accounts for 65 ~ 75 parts, 20 ~ 30 parts of ethane, tetrafluoroethane 5 parts;Realize-
