  • Patent number: 11397035
    Abstract: An air conditioning apparatus includes, a first heat exchanger, a second heat exchanger configured to exchange heat between a first heat medium and a second heat medium, flow rate control valves, and a pump. In a heating mode, a controller is configured to open the flow rate control valve corresponding to a heat exchanger, of the third heat exchangers, to which a request for air conditioning has been made, and to close the flow rate control valve(s) corresponding to a heat exchanger(s), of the third heat exchangers, to which the request for air conditioning has not been made. In a defrosting mode, when a temperature of the second heat medium is lower than a first determination temperature, the controller is configured to open at least one of the flow rate control valve(s) corresponding to the heat exchanger(s) to which the request for air conditioning has not been made.

  • Patent number: 11375163
    Abstract: A vehicle inspection device includes a camera mounted to a power folding side-view mirror provided to a vehicle, the camera being configured to switch between an exterior image capture state in which an exterior of the vehicle is within an image capture range and an interior image capture state in which an interior of the vehicle is within the image capture range, while the side-view mirror performs an opening/closing operation between a completely open state and a closed state, and a vehicle processor that executes a vehicle image capture process of capturing an image of the exterior of the vehicle by the camera when the camera has entered the exterior image capture state due to an operation of the side-view mirror, and capturing an image of the interior of the vehicle by the camera when the camera has entered the interior image capture state due to an operation of the side-view mirror.

  • Patent number: 11333388
    Abstract: When a state in which a driving voltage of a pump is set to an upper limit voltage and an opening degree of at least one of a plurality of flow rate control valves is set to a maximum opening degree continues for a first determination time period, an operation frequency of a compressor is raised at a first time so as to increase an amount of heat exchange by a second heat exchanger. When an operation stop request is input, or an indoor temperature reaches a set temperature, in at least one of a plurality of third heat exchangers after the first time, the operation frequency of the compressor is lowered or the driving voltage of the pump is lowered.

  • Publication number: 20220090812
    Abstract: An air conditioning apparatus includes a plurality of third heat exchangers and flow rate control valves. In a heating mode, a controller opens a flow rate control valve corresponding to a heat exchanger that is being requested to perform air conditioning of the plurality of third heat exchangers, and closes a flow rate control valve corresponding to a heat exchanger that is not being requested to perform air conditioning of the plurality of third heat exchangers. In a defrosting mode, when a temperature of a second heat medium is lower than a first determination temperature, the controller opens a flow rate control valve corresponding to at least one of the heat exchangers that are not being requested to perform air conditioning. The at least one of the heat exchangers is assigned a higher priority than a remaining heat exchanger that is not being requested to perform air conditioning.

  • Publication number: 20220082283
    Abstract: An air conditioning apparatus includes: a second heat exchanger; a plurality of third heat exchangers; and a plurality of flow rate control valves. In a defrosting mode, when a heat exchanger that is not being requested to perform air conditioning includes a first device having a set temperature lower than or equal to a current room temperature and a second device which is set so as not to perform air conditioning, a controller is configured to control a first flow rate control valve corresponding to the first device and a second flow rate control valve corresponding to the second device such that a degree of opening of the first flow rate control valve is higher than or equal to a degree of opening of the second flow rate control valve.

  • Publication number: 20210341193
    Abstract: An air conditioning device has: a refrigerant circuit that is formed of a compressor, a switching valve, a cascade heat exchanger, an expansion valve and an outdoor heat exchanger connected to one another by a first pipe through which a refrigerant flows, and capable of performing a defrosting operation in which the refrigerant discharged from the compressor is introduced into the outdoor heat exchanger; a heat-transfer medium circuit that is formed of a pump, the cascade heat exchanger, and the indoor heat exchanger connected to one another by a second pipe through which a heat-transfer medium flows; and a control device that controls the compressor and the pump. When an amount of heat storage of the heat-transfer medium is less than a threshold, the control device reduces the heating capability of the indoor heat exchanger when the air conditioning device transitions from a heating operation to the defrosting operation.

  • Publication number: 20210310688
    Abstract: When heating is being performed, and a temperature detected by a temperature sensor is lower than a first determination value, a controller opens the flow rate control valve corresponding to a heat exchanger, of the third heat exchangers, to which a request for air conditioning has not been made, and closes the flow rate control valve corresponding to a heat exchanger, of the third heat exchangers, to which the request for air conditioning has been made. When heating is being performed, and the temperature detected by the temperature sensor is higher than a second determination value, the controller opens the flow rate control valve corresponding to the heat exchanger to which the request for air conditioning has been made, and closes the flow rate control valve corresponding to the heat exchanger to which the request for air conditioning has not been made.

  • Publication number: 20210041130
    Abstract: An air conditioning apparatus has a first mode and a second mode as operation modes. In the first mode, a degree of opening of a first flow rate adjustment valve is fixed to a first degree of opening smaller than 100% and greater than 0%, and an operation frequency of a compressor is varied in accordance with air conditioning performance required of a third heat exchanger. In the second mode, the degree of opening of the first flow rate adjustment valve is varied in accordance with air conditioning performance required of the third heat exchanger. When a difference between the air conditioning performance required of the third heat exchanger and air conditioning performance offered by the third heat exchanger becomes greater than a determination value, the operation mode is changed from the first mode to the second mode.
