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.

摘要： There are included: a refrigerant circuit which includes a compressor 3, an outdoor heat exchanger 5, an expansion valve 7, and an evaporator 9, and through which refrigerant circulates; an outdoor fan 6; an indoor fan 10; a measurement unit 41 a configured to measure an operating state variable of the refrigerant circuit; and a control unit 41 b configured to control a manipulated variable of an operational object, which is at least one of a frequency of the compressor 3, an opening degree of the expansion valve 7, a rotation speed of the outdoor fan 6, or a rotation speed of the indoor fan 10, so that a current value of a controlled object, which is one measurement of measurements obtained by the measurement unit 41 a, reaches a target value of the controlled object determined based on measurements other than the one measurement. 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.

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： 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： Provided is an air-conditioning apparatus configured so that a decrease in a refrigeration capacity can be suppressed without increasing the amount of refrigerant with which a refrigerant circuit is filled and that refrigerant can be suitably stored during a pump down operation. The air-conditioning apparatus includes a first on-off valve 11 provided at a pipe between an expansion valve 7 and a use side heat exchanger 6, a bypass 20 branching from a pipe between the expansion valve 7 and the first on-off valve 11 and connected to a pipe at a suction-side of a compressor 3, and a refrigerant storage unit configured to store the refrigerant having passed through the bypass 20. In a pump down operation in which the compressor 3 operates with the first on-off valve 11 being in a closed state, the refrigerant having flowed out from the heat source side heat exchanger 9 flows into the bypass 20, and then, is stored in the refrigerant storage unit.
