    摘要： A torque estimating device of a compressor for an ejector-type refrigerant cycle device includes a high pressure detector disposed to detect a physical amount having a relation with a high-pressure side refrigerant pressure of a refrigerant cycle, an evaporation pressure detector disposed to detect a physical amount having a relation with a refrigerant evaporation pressure in a suction side evaporator, a pressurizing estimating portion for estimating a pressurizing amount in a pressure increasing portion of an ejector to be increased in accordance with an increase of a pressure difference between the high-pressure side refrigerant pressure and the refrigerant evaporation pressure, and a suction pressure estimating portion for estimating a suction refrigerant pressure of the compressor by using the pressurizing amount estimated by the pressurizing estimating portion. Thus, a drive torque of the compressor can be accurately estimated in the ejector-type refrigerant cycle device.

    摘要： A refrigerant cycle device for a vehicle includes a compressor which compresses and discharges refrigerant, a discharge capacity control portion which controls a discharge capacity of the compressor. The refrigerant cycle device further includes a noise determination portion which determines whether an audible noise other than a refrigerant passing noise is in a low noise state, and/or a load determination portion which determines whether an air-conditioning thermal load is in a high load state. The discharge capacity control portion performs a gradual activation control in which the discharge capacity of the compressor is set to be lower than that determined in a normal control, when the noise determination portion determines that the audible noise is in the low noise state, and/or when the load determination portion determines that the air-conditioning thermal load is in the high load state, at an activation time of the compressor.

    摘要： An air-conditioning system allows adjustment of the vented air temperature of a rear seat evaporator. An electronic control system judges whether the surface of the rear seat evaporator is frosting up when 1) a target blowing rate of the rear seat blower is lower than a predetermined value, 2) a detected temperature of evaporator vented air is lower than a specified temperature TEa, and 3) a detected temperature of the outside air is lower than a specified temperature TAMa. A target temperature TEO is raised at this time, so that an electric motor of an electric compressor is stopped and refrigerant no longer flows into the rear seat evaporator. The surface temperature of the rear seat evaporator rises so that the rear seat evaporator can be defrosted.

    摘要： In a refrigeration cycle device with a capacity-variable compressor, a preset suction pressure that serves as a target value of a refrigerant suction pressure of the compressor is calculated and a refrigerant discharge capacity of the compressor is controlled by operating a capacity varying portion such that the suction pressure of the compressor is appreciated to the preset suction pressure. A thermal load detection portion is configured to detect a thermal load of a refrigeration cycle, and a refrigerant flow amount detection portion is configured to detect a flow amount of refrigerant circulating through the refrigeration cycle. In the refrigeration cycle device, a pressure at a predetermined part of the compressor is estimated based on the thermal load detected by the thermal load detection portion and on the flow amount detected by the refrigerant flow amount detection portion.
