摘要： PROBLEM TO BE SOLVED: To secure smooth build-up of a refrigeration cycle in restarting a compressor without damaging comfortability of indoor environment, by changing a restart inhibiting time of the compressor after stopping the compressor in response to an operation mode just before stopping in an air conditioner allowing a reheating dehumidifying operation.
SOLUTION: When the operation mode just before stopping is a heating cycle dehumidifying operation in stopping the compressor, for example, longest six-minute mask is set when outside temperature Ta is lower than 10°C, five-minute mask is set for 10°C ≤ Ta ≤ 15°C, and four-minute mask is set for 15°C ≤ Ta. Three-minute mask is set when the operation state just before the stopping of the compressor is other than the reheating dehumidifying operation.

摘要： PROBLEM TO BE SOLVED: To start, at the time of cooling dehumidifying operation, the cooling dehumidifying operation after performing cooling operation for a predetermined time only when the compressed state of a refrigerant in an outdoor heat exchanger is poor (the compression is not better).
SOLUTION: In an air conditioner in which an expansion valve having a pressure reducing function varied depending on the direction of carrying the refrigerant is interposed between two divided indoor heat exchangers to perform cooling dehumidifying operation or heating dehumidifying operation by use of the expansion valve, the compressed state of the refrigerant in the outdoor heat exchanger is determined, at the time of the cooling dehumidifying operation, in reference to the previous operation mode, the stopping time of a compressor, and the temperature of the outdoor heat exchanger (steps ST2-ST4). On the basis of this, it is determined whether the cooling dehumidifying operation is started without cooling operation or after performing the cooling operation for a determined time.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner capable of sufficiently exhibiting the heat exchange capacity at a heat exchanger.SOLUTION: A CPU 110 makes reference to a coefficient table for obtaining a coefficient 1 and a coefficient 2, and calculates a target pressure difference using these coefficients and refrigerant cycle quantities. When an indoor heat exchanger 51 functions as an evaporator, the CPU captures a pressure difference between a first pass 71 and a second pass 72 that have been detected by a pressure difference sensor 60. If this pressure difference is greater than the target pressure difference, the opening of a first expansion valve 52 is made smaller than the current level, and the opening of a second expansion valve 53 is made greater. Meanwhile, if the pressure difference between the first pass and the second pass is smaller than the target pressure difference, the opening of the first expansion valve is made greater than the current level and the opening of the second expansion valve is made smaller by the CPU. Because of the foregoing control, the pressure difference between the first pass and the second pass gets closer to the target pressure difference.
摘要翻译：要解决的问题：提供一种能够充分发挥热交换器的热交换能力的空调。解决方案：CPU110参考用于获得系数1和系数2的系数表，并计算目标压力差使用这些系数和制冷剂循环量。当室内热交换器51用作蒸发器时，CPU捕获由压力差传感器60检测到的第一通路71和第二通道72之间的压力差。如果该压力差大于目标压力差，使第一膨胀阀52的开度小于当前水平，并使第二膨胀阀53的开度更大。同时，如果第一次通过和第二次通过之间的压力差小于目标压力差，则使第一膨胀阀的开度大于当前水平，并且通过CPU使第二膨胀阀的打开减小。由于上述控制，第一次通过和第二次通过之间的压力差越来越接近目标压力差。

摘要： PROBLEM TO BE SOLVED: To provide a control process of an air conditioner which can prevent vibration of a decompression valve provided in a bypass tube of an interior unit or noises caused thereby at the time of cooling and dehumidifying operations and can thus perform smooth cooling and dehumidifying operations.
SOLUTION: At the time of start of cooling and dehumidifying operations, in the case where the temperature of an exterior heat exchanger 7 is a predetermined value or less, the operation is temporally switched from the cooling and dehumidifying operation to a cooling operation. Then, the cooling operation is continued for a predetermined period of time, thereby reducing the pressure differential between a branching section A and a branching section B located at both ends of a bypass tube 13 provided with a second expansion valve 15. Thereafter, the operation is switched to the cooling operation again, thereby suppressing the vibration or noises of the second expansion valve 15.
