摘要： PROBLEM TO BE SOLVED: To prevent abnormal vibration caused by the rotating speed of a compressor and high pressure of a refrigerating cycle by stopping a compressor when the high pressure of a refrigerating cycle is higher than a preset designat ed pressure and the compressor is low rotating speed, and the rotating speed is lower than a preset designated rotating speed. SOLUTION: When the rotating speed of a compressor 21 is influenced by hot water temperature and the high pressure is higher, a coolant compressor 21 becomes loaded condition with low rotation and high torque to cause abnormal vibration. When the high pressure detected by a high pressure sensor 43 is higher than designated pressure, the coolant compressor 21 is stopped, and when lower than designated pressure, it is operated. Thus, the coolant compressor 21 will not become loaded condition with low rotation and high torque so as to prevent abnormal vibration of the coolant compressor 21. At the time of stopping the coolant compressor 21, the control condition of a fan 9 keeps the condition immediately before the coolant compressor 21 is stopped, and thereby the interior of vehicle can be heated even during the compressor stop.

摘要： PROBLEM TO BE SOLVED: To reliably clear the fogging of a window in a short time by controlling the operation mode to a cooling mode, a cooling/dehumidifying mode or a heating/dehumidifying mode based on the temperature difference between the outside air temperature and target blowout temperature when dehumidification in a vehicle room is desired. SOLUTION: During the transition from the normal 'AUTO' state of an air conditioning unit 1 to 'DEF' control, if the operation mode before the transition is a cooling mode and the target blowout temperature is lower than (outside air temperature -15 deg.C) or the target blowout temperature is 3C or below, an outside air introduction cooling mode is selected. If the operation mode before the transition is a cooling mode and the target blowout temperature is higher than (outside air temperature -15 deg.C), a cooling/dehumidifying mode is selected. If the operation mode before the transition to 'DEF' control is a heating mode, a heating/dehumidifying mode is selected. A vehicle room is immediately dehumidified, and the fogging of a front window glass can be removed.

摘要： PROBLEM TO BE SOLVED: To eliminate any undesirable matter when target water temperature stays below the water temperature in the case of minimum performance of a combustor by setting a blow out wind quantity toward the inside of a cabin to a preset wind quantity more than the wind quantity calculated by a target blow out quantity calculation means when the target heating capacity of the combustor stays below the minimum capacity. SOLUTION: When a power supply current is supplied to the controller of an air conditioner, the controller makes initialization of its routine and receives a signal from an ignition switch and signals from respective sensors. And it is judged whether the external air temperature detected by an external air temperature sensor is below the specified low external air temperature or not (S140). Furthermore, a magnitude difference between a blow out temperature TAR detected by a blow out temperature detector and the target blow out temperature TAO is judged. When TAR>=TAO+α (α is a constant) is judged satisfactory (S150), the voltage of the blower motor is so controlled as to set the blow out wind quantity into the cabin to the preset wind quantity (S170).

摘要： PROBLEM TO BE SOLVED: To constantly improve the operating efficiency of a refrigerating cycle regardless of air-conditioning load. SOLUTION: A judgement reference value (a) is determined in response to the outside atmospheric temperature which expresses air-conditioning load, according to step 125. According to step 140 during the period of cooling- operation mode, and according to step 230 during the period of heating-operation mode, it is judged whether the input current IDC to an electric motor for driving a compressor is smaller than the judgement-reference value (a) or not. In this case, when the judgement-reference value is judged to be greater (NO), namely it is judged that the power consumption of the electric motor exceeds a specified value, an inverter is controlled so that the IDC is equal to the judgement- reference value (a), according to steps 210, 280. Thus, since the IDC is constantly controlled so that it does not exceed the judgement-reference value (a), the power consumption of the electric motor is constantly below a specified value, and a specified size of the coefficient (COP) of operation of a refrigerating cycle can be ensured.
