摘要： If a refrigerant mixture of carbon dioxide (R744) is used in a refrigeration cycle apparatus, a pressure and a discharging temperature are increased. It is an object of the present invention to solve these problems and to obtain more excellent characteristics. A refrigerant mixture comprises carbon dioxide (R744) having non-azeotropic properties and hydrocarbon refrigerant comprising one of propane, cyclopropane, isobutane and butane. If the hydrocarbon refrigerant is propane, the concentration of R744 in the entire refrigerant mixture is 30% or lower by weight. If the hydrocarbon refrigerant is cyclopropane, the concentration of R744 in the entire refrigerant mixture is 40% or lower by weight. If the hydrocarbon refrigerant is isobutane, the concentration of R744 in the entire refrigerant mixture is 60% or lower by weight. If the hydrocarbon refrigerant is butane, the concentration of R744 in the entire refrigerant mixture is 70% or lower by weight. The refrigerant mixture is charged into a refrigeration cycle apparatus.

摘要： In an apparatus having a refrigeration cycle, the refrigeration cycle is formed by annularly connecting a compressor (1), a condenser (3), an expansion device (4) and an evaporator with one another, the apparatus uses propane, isobutane or ethane as a refrigerant, and uses refrigerating machine oil having less mutual solubility with the refrigerant, and a dryer (6, 100) is provided in the refrigeration cycle for absorbing water. Instead of the dryer (6, 100), an additive which reacts with water may be included in said refrigerating machine oil. With this arrangement, the amount of the refrigerant can be reduced, and the long term reliability of the apparatus can be obtained.

摘要： In a refrigeration cycle using a flammable refrigerant as a refrigerant and comprising an indoor heat exchanger (6), an outdoor heat exchanger (3), a compressor (1) and an expansion device (5) which are annularly connected to one another through pipes, the refrigeration cycle is provided with a gas sensor (8) and a refrigerant discharge portion (9), the gas sensor (8) monitors leakage of the refrigerant from the refrigeration cycle to outside, and after the leakage is detected by the gas sensor (8), the discharge portion (9) is opened to discharge the refrigerant to outside. At that time, the gas sensor (8) is disposed inside a room, and the discharge portion is disposed outside the room. Further, the discharge portion (9) is provided with a fan (19) to facilitate the dispersion of the refrigerant. Further, the discharge portion (9) is provided with a burner portion (29) to discharge out the refrigerant while burning the refrigerant. With the above structure, the leakage of a flammable refrigerant is monitored, and after the leakage is detected, the refrigerant is positively discharged to the safe atmosphere, e. g. to the side of an outdoor unit, and even if the refrigerant is leaked at the side of an indoor unit, it is possible to suppress the leakage to a certain level.
