Abstract: In a refrigerating apparatus comprising a rotary compressor, a fluid-controlled valve is inserted in the path between a condenser and a evaporator and a reverse flow check valve is inserted between the evaporator and a suction line connected to the input port of the rotary compressor. Unwanted heat load caused by flow of high pressure refrigerant into the evaporator, then the rotary compressor stops, is thereby eliminated.

Abstract: PURPOSE:To make cool air naturally flow down toward areas apart from an indoor unit and to realize an ideal temperature distribution in a room that the head is kept cool and the feet is kept warm, by a method wherein a ceiling opening, which connects a ceiling chamber and the inside of the room, is provided on a ceiling board, and a floor opening, which connects a hollow space and the inside of the room, and a floor ventilation hole are provided on the double floor. CONSTITUTION:During heating operation, warm air is blown at an extremely low velocity through a floor ventilating hole 15, which is provided nearby the edge of a double floor 5, and a floor connecting hole 16 which is provided at a desired position, and is sucked into a ceiling opening 32 provided in a ceiling board 2 to develop a warm air circulating flow. During cooling operation, as cool air is blown through the ceiling opening 32 provided in the ceiling board 2, and sucked into the floor ventilating hole 15 and the floor connecting hole 16 provided in the double floor 5 to produce a gravity down flow of cool air, a very uniform temperature distribution is achieved without uncomfortable feeling. In addition, as a space in a double-glazed window is used as a cold or warm air passage, discomfort due to radiation from outside in summer and due to cold radiation and cold draft in winter, and dew formation on the window glass can be prevented, so that a high grade air conditioning can be realized.

Abstract: PURPOSE:To make an ideal distribution of temperature with a cold head and warm feet state within a room by a method wherein an indoor unit is provided with blowing ports opened at a hollow part of a double floor, blowing ports opened into the room, blowing ports changing-over means and the double floor is provided with aeration ports communicating with the room at end portions and communication holes communicating with the room at any optional positions. CONSTITUTION:When a cooling operation is carried out, a fan 18 is rotated normally, air flowed as indicated by a dotted arrow line, passed through a heat exchanger 4 and cooled there is directed upwardly from upper blowing ports 16, strikes against a ceiling, descends by its own weight while expanding downwardly. After the air cools a dwelling area, the air is sucked through an aeration port 23 and a communication hole 24, passes through a hollow part 22 of a double floor 21 and further the air is sucked at a lower blowing port 17. In turn, when a heating operation is carried out, the fan 18 is rotated in a reverse direction, the hot air is blown from the lower blowing port 17 as indicated by a solid line, the air passes through the hollow part 22 and is blown out of an aeration port 23 and the communication hole 24. At this time, the hot air passes while heating the double floor 21 from below it, resulting in that a temperature of the floor 21 is increased and then a room 2 is indirectly heated with a natural convection flow. The hot air passed from the aeration port 23 and the communication hole 24 is sucked into the blowing ports 16.

Abstract: PURPOSE:To invariably feed a lubricant regardless of the inclination of a compressor by inclining and connecting two pairs of semi-enclosed containers nearly in a V-shape to form an enclosed container and arranging one end of oil feed mechanisms at the center bottom section of the enclosed container. CONSTITUTION:Two pairs of semi-enclosed containers 16 and 16a opened on compressor sections 14 and 14a respectively are inclined and connected to each other so that the compressor sections 14 and 14a are faced together and the compressor sections 14 and 14a are made lower than motor sections 15 and 15a to form an enclosed container 18. Oil feed mechanisms 17 and 17a communicated to the compressor sections 14 and 14a at one end and communicated to the center bottom section 19 of the enclosed container 18 at the other end are arranged. Even when a compressor is obliquely installed, a lubricant 3 is accumulated at the center bottom section of the enclosed container 18, oil feed springs 13 and 13a in oil feed pipes 12 and 12a are submerged in the lubricant 3, and the lubricant 3 can be fed.

Abstract: PURPOSE:To make it possible to obtain an ideally comfortable airconditioning performance which can keep the head cool and the feet warm by providing an upper blowoff port and a lower blowoff port, connecting said lower blowoff port with a hollow section in a double floor, and boring an opening which penetrates the double floor and communicates with the hollow section and a room. CONSTITUTION:A upper blowoff port 16 is installed to the upper part of an indoor airconditioner while a lower blowoff port 17 is installed to the lower part. The lower blowoff port 17 is connected with a hollow section 22 in a double floor 21. The double floor 21 is provided with openings 23a, 23b,...23x which communicate with the hollow section 22 and a room 2 which are laid out uniformly over the entire floor. When a fan 18 makes a normal rotation during cooling operation, the air is adapted to flow upward, passing through a heat exchanger 4 so that the cooled air may be discharged upward from the upper blowoff port 16. The fan 18 is designed to make a reverse rotation during heating operation. The hot air is discharged from the lower blowoff port 17, passing through the hollow section 22 in the double 21 so that the hot air may be discharged from the opening sections 23a, 23b,...23x.
