摘要： In a scroll compressor, at an end plate surface of a fixed scroll, an annular back pressure groove connected to a back pressure chamber is provided, and an arc-shaped first groove and an arc-shaped second groove are provided inside the back pressure groove in a radial direction. A distance between the second groove and the back pressure groove is shorter than a distance between the first groove and the back pressure groove. A revolving scroll is provided with a first hole and a second hole for guiding lubricant oil from an oil supply path to the end plate surface side of the fixed scroll. At least part of a movement locus of an opening of the first hole is included in the first groove. At least part of a movement locus of an opening of the second hole is included in the second groove. The first groove and the second groove at least partially overlap with each other in the radial direction.

摘要： A scroll compressor includes a hermetic container, a fixed scroll, a swing scroll, a frame, an electric motor, and a shaft. A first groove and a second groove are provided outside a fixed wrap in a radial direction at an end plate surface of the fixed scroll. An oil supply hole for guiding lubricant oil from a through-hole opens at an end plate surface of the swing scroll. A single opening of the oil supply hole alternately communicates with the first groove and the second groove along with swing of the swing scroll.

摘要： Provided is an indoor unit of an air-conditioner including: an indoor unit body configured to be provided in a ceiling; a suction port attached to a lower surface of the indoor unit body; a panel including a blow port for blowing conditioned air into a room; and a louver provided at the blow port of the panel to change an air sending direction. The panel includes an outer frame provided outside the blow port and provided with a substantially horizontal flat portion, and a protruding portion provided on the flat portion of the outer frame and protruding vertically downward. A lower end of the protruding portion is positioned vertically above a lower end of the louver. A lower end of an inner flow path wall surface forming a flow path wall surface inside the blow port is positioned vertically below the lower end of the louver.

摘要： An air-conditioner which performs an appropriate control in the event of a leak of refrigerant. The air-conditioner includes a refrigerant circuit, a refrigerant leak sensor which senses a leak of refrigerant in the refrigerant circuit, an indoor fan which delivers air to the indoor heat exchanger, and an indoor control circuit which, upon sensing a leak of refrigerant by the refrigerant leak sensor, controls the indoor fan based on whether the refrigerant sealed in the refrigerant circuit is flammable.

摘要： An air-conditioning device including multiple outdoor units and an indoor unit through a pipe includes a control section that obtains a degree of subcooling at an outlet of a subcooling circuit of each outdoor unit based on a temperature detected by a temperature sensor that detects the temperature of refrigerant having passed through the subcooling circuit of each outdoor unit, obtain a target value of the degree of subcooling based on the obtained multiple degrees of subcooling, and perform the control of increasing the rotation speed of a compressor of an outdoor unit having a higher degree of subcooling than the target value and decreasing the rotation speed of a compressor of an outdoor unit having a lower degree of subcooling than the target value such that a difference in the degree of subcooling at the outlet of the subcooling circuit of each outdoor unit is decreased.

摘要： A refrigeration cycle, an air conditioning system, and a method for controlling a refrigeration cycle are provided. The refrigeration cycle includes an outdoor unit, an indoor unit, a controller, and an inverter. The controller controls a compressor and an outdoor fan of the air conditioning system so as to minimize a total electric power consumption of the air conditioning system. The inverter controls the outdoor fan in a rotation state predicted from a capacity demand in an air conditioning space depending on an operation mode and sensor values. The controller predicts the capacity demand and controls a rotation rate of the outdoor fan based on a prediction of the capacity demand.
