Abstract

Substitute fluorocarbons (HCFC and HFC) for chlorofluorocarbons are replaced with a hydrocarbon refrigerant which is a natural refrigerant to render the elimination of chlorofluorocarbons with the hydrocarbon refrigerant as a natural refrigerant possible. Thus, the substitute fluorocarbons are diminished and energy saving in refrigerators or air conditioners is attained. A hydrocarbon mixture refrigerant is provided which contains propane and has a saturated vapor pressure at 7 DEG C of 0.3-1 MPa and a saturated vapor pressure at 35 DEG C of 0.6-2.2 MPa. It may further contain n-butane, isobutane, and ethane. The hydrocarbon mixture refrigerant preferably has a boiling point of -20 DEG C or lower.

Description

technical field [0001] The present invention relates to a hydrocarbon mixed refrigerant free of chlorofluorocarbons (chlorofluorocarbon) or chlorofluorocarbon substitutes, a freezing / refrigeration or refrigeration / heating air-conditioning system using it, and a freezing / refrigeration system using the aforementioned hydrocarbon mixed refrigerant. A refrigeration or refrigeration / heating air-conditioning method, and a method of manufacturing a refrigeration / refrigeration or refrigeration / heating air-conditioning system. Background technique [0002] So-called chlorofluorocarbons (CFCs; hydrochlorofluorocarbons), such as dichlorodifluoromethane (CFC12) and chlorotrifluoromethane (CFC13), have been used in air conditioners or refrigerators for a long time. of refrigerant. However, the use of HCFCs has been completely banned due to the serious damage to the global environment caused by HCFCs degrading the ozone layer. Therefore, HCFCs (hydrochlorofluorocarbons) such as dichloro...
