摘要： An apparatus includes a refrigerant circuit in which a compressor 1 that compresses a refrigerant, an outdoor heat exchanger 2 serving as a radiator that exchanges heat between the refrigerant and a heating target, an expansion valve 4 that decompresses the refrigerant by opening-degree adjustment, and an indoor heat exchanger 3 serving as an evaporator that exchanges heat between a heat-exchange target and the refrigerant are connected by pipes. The apparatus includes: an outdoor air temperature sensor 41 that detects a temperature of outdoor air serving as the heat-exchange target; a discharge temperature sensor 21 that detects a discharge temperature of the refrigerant discharged by the compressor 1; and a controller 101 that, when the controller 101 determines that a rotation speed of the compressor 1 is a maximum and the temperature of the heat-exchange target is lower than a preset temperature, controls an opening degree of the expansion valve 4 by using the discharge temperature.

摘要： To improve the separation efficiency of a gas-liquid separator in the gas-liquid separator and an air conditioner, the gas-liquid separator having a vessel with an inlet pipe and an outlet pipe is arranged such that an exit end section of the inlet pipe is formed to be closed or to have a gap, an expanded end section having a width greater than the diameter of that portion of the inlet pipe which crosses a container of the gas-liquid separator is provided, and that a lateral hole is formed in a side face of the expanded end section. Refrigerant vapor and refrigerant liquid are efficiently separated from each other at the expanded end section, and this improves separation efficiency of the gas-liquid separator.

摘要： When a controller (10) determines that a leakage of refrigerant occurs, the controller (10) executes a control of rotating an air-sending fan (4) at high rotation speed. After the control, the controller (10) executes a control of stopping rotation of the air-sending fan (4) or reducing a rotation speed of the air-sending fan (4) in accordance with a result of detection by a first refrigerant sensor (28) provided in a lower portion of a heat exchanger chamber (1). Thus, the air-sending fan (4) is prevented from continuing the rotation at high rotation speed. Therefore, an indoor unit for an air-conditioning apparatus is excellent in safety and is capable of avoiding feeling of discomfort of a user due to the high-speed rotation of the air-sending fan.

The control unit 41 b determines, while the current value is lower than a lower limit value of an upper limit value and the lower limit value of a settling range in which the target value is centered, the manipulated variable by using the upper limit value as a target value, determines, while the current value is higher than the upper limit value, the manipulated variable by using the lower limit value as a target value, and determines, after the current value falls within the settling range, the manipulated variable based on a reference allowable overshoot ratio Xb, which is a preset overshoot ratio.

摘要： A pipe joint (10) is connected with a connecting pipe (101), and includes a pipe joint body (20) and a nut member (30). When the connecting pipe (101) formed with a bead (101a) expanded in the radial direction is connected with this pipe joint (10), a male thread (25) of the pipe joint body (20) is engaged with a female thread (33) of the nut member (30) to hold the bead (101a) between a tapered face (22) and a tapered face (34). In addition, the joined portion between the bead (101a) and the tapered face (22) forms a first sealed portion, and a joined portion between the bead (101a) and the tapered face (34) forms a second sealed portion. Still further, a tapered face (24) of the pipe joint body (20) is joined with the tapered face (34) of the nut member (30) to form a third sealed portion.

摘要： A refrigeration air conditioning device, according to the present invention, provided with a refrigeration cycle circuit that comprises a compressor, a condenser, a decompression device, refrigerant conduits connecting the condenser and the decompression device, and an evaporator, and that is filled with refrigerant. The refrigerant conduits include an ascending conduit that extends in the up-down direction and through which the liquid refrigerant flowing out from the condenser ascends. The density of a refrigerator oil stored in the compressor is greater than the density of the refrigerant when the latter is in liquid form. When the conduit inner diameter is defined as the inner diameter of the ascending conduit, spherical refrigerator oil is defined as refrigerator oil having a spherical shape and a diameter equal to the conduit inner diameter, and fluid force is defined as force applied to the spherical refrigerator oil by the liquid refrigerant ascending through the ascending conduit, the speed of the liquid refrigerant ascending through the ascending conduit is such that the fluid force is greater than the gravitational force acting upon the spherical refrigerator oil.
