摘要： In a refrigeration cycle using a flammable refrigerant as a refrigerant and comprising an indoor heat exchanger, an outdoor heat exchanger, a compressor and an expansion device which are annularly connected to one another through pipes, the refrigeration cycle is provided with a gas sensor and a refrigerant discharge portion, the gas sensor monitors leakage of the refrigerant from the refrigeration cycle to outside, and after the leakage is detected by the gas sensor, the discharge portion is opened to discharge the refrigerant to outside. At that time, the gas sensor is disposed inside a room, and the discharge portion is disposed outside the room. Further, the discharge portion is provided with a fan to facilitate the dispersion of the refrigerant. Further, the discharge portion is provided with a burner portion 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.

摘要： In an apparatus having a refrigeration cycle, the refrigeration cycle is formed by annularly connecting a compressor, a condenser, an expansion device 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 is provided in the refrigeration cycle for absorbing water. In stead of the dryer, 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 compressor of a refrigeration cycle using an HC-based refrigerant and a lubricant having specific gravity greater than that of the HC-based refrigerant and having no or no or less mutual solubility with the HC-based refrigerant, an oil reservoir is formed on a bottom of the compressor, the oil reservoir is provided at its portion with a recess, a suction port of a lubricant suction pipe for supplying the lubricant to a compressor mechanism is provided in the recess. With this feature, it is possible to sufficiently supply the lubricant to the compressor even when the lubricant has no or less mutual solubility, so that even if the amount of the lubricant is reduced, the lubricant can be sufficiently sucked from an inlet port of a lubricant pumping pipe and supplied to the compressor mechanism.

摘要： A refrigerator controller employs a non-azeotropic mixture refrigerant and a compressor, a four-way valve, an outdoor hear exchanger, a fractionator, an overhead condenser provided on the top of the fractionator, a first flow control valve, a throttle, and an indoor heat exchanger which are connected in the form of a ring. The controller further employs a circuit at a lower part of the fractionator returning to the bottom of the fractionator through a second flow control valve and a reheater, and a circuit returning from the overhead condenser to the top of the fractionator, thereby controlling the openings of the first and second flow control valves by the output signal of indoor and outdoor heat exchanger temperature detectors, an indoor temperature detector, and an indoor temperature setting device through a flow controller. In this manner, a wider control range of refrigerating capability can be realized. Thus a high separation effect for mixed refrigerant components is obtained while controlling a safe and optimum refrigerant cycle.

摘要： An explosion preventing device for a refrigerating machine using a flammable refrigerant according to a first embodiment of the present invention comprises a mesh member which covers a part or component or a control section. The mesh member has a mesh size which is equal to or smaller than a quenching distance for the flammable refrigerant used. By covering the part or the like which may generate electric sparks, with the mesh member having the mesh size equal to or smaller than a quenching distance, as described above, even if the sparks are generated to produce flames, when the refrigerant is leaked, the flames cannot be propagated to the outside of the mesh member. Therefore, even if the sparks are generated when the refrigerant is leaked, a serious explosion or fire cannot be caused.
