A control unit is configured to set a rotation speed of a compressor to be lower than that in a defrosting operation and set an opening degree of a pressure reducing device to be equal to or greater than that in the defrosting operation during a first control time after completion of the defrosting operation, stop the compressor and set the opening degree of the pressure reducing device to be less than that in the first control time during a second control time after lapse of the first control time, and control a refrigerant circuit switching device to resume a heating operation after lapse of the second control time.

Air-conditioning apparatus

An accumulator includes a container, a low pressure refrigerant inlet tube, and a low pressure refrigerant outlet body including an upstream-side tubular section, a low pressure refrigerant turning back section and a downstream-side tubular section in the container. At least a part of the upstream-side tubular section is covered by a first outer tube with a gap between the upstream-side tubular section and the first outer tube, at least a part of the downstream-side tubular section is covered by a second outer tube with a gap between the downstream-side tubular section and the second outer tube, the first outer tube and the second outer tube communicate with each other via a bridging tube, and high pressure refrigerant passes through the gap between the upstream-side tubular section and the first outer tube, the bridging tube, and the gap between the downstream-side tubular section and the second outer tube.

Accumulator, air-conditioning apparatus and method for manufacturing accumulator

A refrigeration cycle apparatus includes a refrigerant circuit connecting a compressor, a heat source-side heat exchanger, an expansion device, and a use-side heat exchanger to each other by connecting pipes, an outside air temperature sensor configured to detect an outside air temperature, and a controller configured to operate the refrigeration cycle apparatus and to switch between a normal operation mode for controlling the refrigerant circuit based on an operation load of the use-side heat exchanger and a refrigerant amount determining mode for determining whether or not an amount of refrigerant in the refrigerant circuit is appropriate. The controller is configured to switch the normal operation mode to the refrigerant amount determining mode when the outside air temperature detected by the outside air temperature sensor is within a set temperature range.

Refrigeration cycle apparatus

An air-conditioning apparatus controls a decrease in efficiency of a refrigeration cycle, and includes a suction pipe having one end connected to a suction side of a compressor and an other end connected to an evaporator, a receiver connected to a refrigerant pipe connecting the evaporator and a condenser to each other, a first bypass pipe having one end connected to the receiver and an other end connected to the suction pipe and configured to supply refrigerant from the receiver to the suction pipe, a flow control valve provided to the first bypass pipe, a heat recovery portion disposed downstream of a portion of the suction pipe connected to the first bypass pipe, and a control device configured to control an opening degree of the flow control valve based on a degree of superheat of refrigerant in the heat recovery portion.

It is determined whether thermo-off postponement control is allowed or not on the basis of a current compressor operating frequency when a thermo-off condition is satisfied. If it is determined that thermo-off postponement control is allowed, the thermo-off postponement control in which a lowest operating frequency in an operating frequency range of a compressor is temporarily reduced within a range greater than or equal to a minimum operating frequency of the compressor in use so as to continue an operation. If it is determined that thermo-off postponement control is not allowed, thermo-off of stopping the compressor is performed.

Air-conditioning apparatus with thermo-off postponement control

In a vehicle with a load-carrying platform, an elastic band is provided so a rear portion of a tailgate and a rear portion of a bed extender enter a tensioned state. A rotation regulation mechanism is provided to the tailgate and the bed extender that regulates further rotational movement by the tailgate and the bed extender making contact when the tailgate is rotated towards a closed position. The bed extender and the tailgate are prevented from rotating in the same direction by the rotation regulation mechanism, and the load on the elastic band is mitigated.

Vehicle with load-carrying platform

In a compressor shell built in an outdoor unit of an air conditioner, a compressor shell thermistor that detects a temperature of the shell is installed. Also, an outside air temperature thermistor that detects an outside air temperature is installed in an outdoor unit. The outside air temperature is compared with the compressor shell temperature, and if the shell temperature is higher than the outside air temperature, a compressor heating device is invalidated. If the shell temperature is lower than the outside air temperature, it is determined as a refrigerant collection condition, and the compressor heating device is operated. Also, if the shell temperature is higher than the outside air temperature by a certain temperature or more, the operation of the compressor heating device is stopped so that wasteful standby power is reduced, and energy of the apparatus is saved.

Air conditioner

Heating equipment, including a first heat exchanger, a compressor, a second heat exchanger, and a first expansion valve that decompresses a refrigerant flowing from the second heat exchanger to the first heat exchanger, are connected so as to circulate the refrigerant. A third heat exchanger provides heat of the refrigerant flowing from the second heat exchanger to the first heat exchanger to the refrigerant flowing from the first heat exchanger toward the compressor. An injection circuit merges part of the refrigerant flowing from the second heat exchanger to the first heat exchanger with the refrigerant that is sucked by the compressor. An injection expansion valve is installed in the injection circuit and decompresses the refrigerant flowing in the injection circuit. A fourth heat exchanger is installed in the injection circuit to supply heat of the refrigerant flowing from the second heat exchanger toward the first heat exchanger to the refrigerant flowing in the injection circuit.

Air conditioner heat pump with injection circuit and automatic control thereof

Refrigeration/air conditioning equipment includes a first internal heat exchanger for exchanging heat between a refrigerant to be sucked in a compressor and a high-pressure liquid refrigerant, an injection circuit for evaporating a bypassed high-pressure liquid at intermediate pressure and injecting the vaporized refrigerant into the compressor, a second internal heat exchanger for exchanging heat between the high-pressure liquid refrigerant and the refrigerant to be injected, and a heat source for heating the refrigerant to be injected.

Refrigeration/air conditioning equipment

A refrigerating air conditioning system is provided with a refrigerant circuit which includes a compressor, an indoor heat exchanger, a first pressure reducing device, an outdoor heat exchanger, and a switching devicefor switching a direction of a refrigerant flow between heating and cooling modes for supplying heat from the indoor heat exchangerIn the system, a refrigerant temperature detection sensorof the outdoor heat exchangerand an outdoor air temperature detection sensorare provided for determining a state of a frost formed on the outdoor heat exchanger. Two types of defrosting inhibition time values &#x3c4;and &#x3c4;are allowed to be set in accordance with a previous defrosting time &#x3c4;for continuously performing heating operation. A defrosting operation is performed by controlling the defrosting inhibition time value to be long when an amount of the frost formed on the outdoor heat exchangeris determined to be small, and the defrosting inhibition time value to be short when the amount of the frost formed on the outdoor heat exchangeris determined to be large.

Refrigerating air conditioning system

To achieve efficient utilization of a display apparatus installed in a motorcycle. Various information is displayed in accordance with an operation of an operation switch set on an information display screen provided below a speedometer. Upon operation of switching a power supply on, an opening ceremony display is displayed. However, upon operation of switching the power supply off, an ending ceremony display is displayed. By displaying vehicle owner information particularly together with the opening ceremony display, a satisfactory feeling of the owner can be obtained.
