摘要 |
<p>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°C of 0.3-1 MPa and a saturated vapor pressure at 35°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°C or lower.</p> |
