    Abstract: A chilling unit and a temperature control system using water circulation includes a refrigerant circuit, a pipe through which a heat medium flows, a flow switching device, a temperature sensor, a pressure sensor, and a controller. The refrigerant circuit includes a compressor, a pair of air-side heat exchangers, an expansion valve, and a heat-medium-side heat exchanger that are connected to each other by pipes, thereby enabling refrigerant to circulate in the refrigerant circuit. The flow switching device switches between refrigerant-circulation routes. The controller controls the compressor in accordance with a target outlet temperature, the temperature of the heat medium detected by the temperature sensor, and a pressure difference in the heat medium detected by the pressure sensor.

  • Publication number: 20190362164
    Abstract: An image recognition device has a searcher, a determiner, and recognizer. The searcher searches for a demarcation line indicating a parking bay based on a first taken image obtained by a first camera taking an image around a vehicle. The determiner determines a parking position at which to park based on the result of searching by the searcher. The recognizer recognizes, after determination by the determiner, the demarcation line based on a second taken image obtained by a second camera taking an image around the vehicle. The recognizer corrects the recognition of the demarcation line in the second taken image based on the result of recognition, obtained in the searcher, of the first taken image.

  • Publication number: 20190154322
    Abstract: A controller in a refrigeration cycle apparatus performs a refrigerant recovery operation when switching an operation mode from a defrosting mode to a heating mode. During the refrigerant recovery operation, by rotating a fan of a blower while monitoring a pressure at a discharge side of the compressor, the controller is configured to perform feedback control to cause a high-pressure side pressure to be close to a high-pressure side target pressure value. During the refrigerant recovery operation, by controlling a driving frequency of the compressor while monitoring a pressure at a suction side of the compressor, the controller is configured to perform feedback control to cause a low-pressure side pressure to be close to a low-pressure side target pressure value.
