Abstract: A refrigerant sensor which generates an output corresponding to the amount of liquid phase refrigerant in contact with the sensor is provided in a closed refrigerant circulation circuit of an air conditioning apparatus. A refrigerant insufficiency is detected by sensing a rotational speed of a compressor and comparing the refrigerant sensor output with a judgment value set to correspond to the rotational speed. As a result, even if the liquid surface of refrigerant in the refrigerant sensor fluctuates corresponding to an increase in rotational speed of the compressor, and an output value greater than that for the actual refrigerant fill amount is generated, since the judgment value is set to counterbalance this, a refrigerant insufficiency can be accurately detected. Moreover, problems such as seizing of the compressor due to the refrigerant insufficiency can be reliably prevented.

Abstract: The fuel character judging system has an electrical capacitance type sensor which outputs a first detection signal representative of a first character of a fuel mixture. A resistance type sensor outputs a second detection signal representative of a second character of the fuel mixture. A control unit stores first and second maps for a known fuel mixture having known first, second and third numbers corresponding to components of the known fuel mixture. The first map has a plurality of first characteristic lines which respectively correspond to a plurality of values of the first detection signal from the electrical capacitance type sensor. The second characteristic lines are plotted in accordance with the second signal from the resistance type sensor upon changing the known first number. One of the second characteristic lines in the second map is selected in accordance with the first detection signal from the electrical capacitance type sensor.

The refrigerator includes a compressor with a bypass circuit or a variable displacement compressor, a state detecting sensor for sensing the degree of separation of the refrigerant mixture, determining circuit for determining whether the detected degree of separation is in a two phase separation area, and a control unit for controlling the amount of the refrigerant passing through the bypass circuit or the displacement of the variable displacement compressor. When the refrigerant mixture enters into the two phase separation area, the amount of discharge or the displacement of the compressor is decreased. The temperature of refrigerant mixture is lowered accordingly and the phase changes from the two phase separation area. The refrigerating machine oil is maintained in a uniformly mixed state with the refrigerant and circulates with the refrigerant to the compressor.

Abstract: An air conditioning system having a circuit for determining whether sufficient refrigerant is present in the system by detecting a phase state of the refrigerant. The circuit comprises a comparison circuit for comparing a detection signal of a state detecting sensor with a first reference value and a second reference value lower than the first reference value. An indication signal is output after the detection signal exceeds the first reference value until the detection signal is less than the second reference value.

The amount of refrigerant in the refrigerant circuit can be accurately determined and maintained within a proper range.
