摘要： PROBLEM TO BE SOLVED: To efficiently reduce material and assembly costs corresponding to the load of an indoor machine by dropping a natural frequency when the set frequency of a compressor becomes equal to the natural frequency of component parts such as piping and heat exchanger of the outdoor machine, and by suppressing the vibration of piping and an outdoor body. SOLUTION: In a compressor frequency operation circuit 62, a load level coefficient is read from a load coefficient table 66 according to the rated capacity signal, difference temperature signal, operation mode signal, and ON-OFF discrimination signal of each of outdoor machines 4a and 4b, the sum of the load level coefficient is multiplied by a constant, further a correction value is added, and the frequency of a compressor is tentatively determined. When the tentatively determined frequency is equal to the preset natural frequency, 1 Hz is added to the tentatively determined frequency for determining the operation frequency of the compressor, thus suppressing the piping crack caused by the vibration of the piping and vibration,to a building caused by the vibration of the body of an outdoor machine 2, and hence constantly performing optimum operation.

摘要： PROBLEM TO BE SOLVED: To provide a method of controlling multi-room air conditioner during change in the number of operating room units which enables efficiently controlling of the degree of combustion and the circulation quantity of a refrigerant according to a demand load from a room even when the number of the operating room units decreases. SOLUTION: During the heating operation, when the total demand load decreases as caused by a decrease in the number of operating room units (S22), the degree of combustion of a refrigerant heater is initially lowered (S23 and S24). After a specified time passes (S25 and S26), an electric expansion valve corresponding to the room unit receiving a stop signal is controlled in the direction of closing (S27). After another specified time, (S31 and S32), the frequency of a compressor is lowered to bring down the circulation quantity of the refrigerant (S33).

摘要： PURPOSE:To enable a wide efficient stable capability controlling operation to be attained, provide a small-sized separator circuit and a simplified circuit by a method wherein either a high boiling temperature refrigerant substance and a low boiling temperature refrigerant substance in separated according to a load and a refrigerant mixing rate is made variable. CONSTITUTION:For example, during a heating operation, a frequency of a compressor is detected by a frequency detector 32, compared with a first set frequency. In case that it is higher than a set frequency, a four-way valve 25 is changed over and a transmitted pat of a separator 101 is connected to a storing device 26. When an electromagnetic opening or closing valve 28 is closed. R-22 easily passing through a function film 103 is cooled by the cooling device 30 and stored in the storing device 26 with the liquid refrigerant. In turn, R-13B1 which hardly passes through the function film 103 exits an outlet pipe 106 and is returned to an inlet port of the evaporator 24 through the four-way valve 25, the connecting pipe 109 and the pressure reducing device 29. Accordingly, a rate of R-22 of the main circuit is decreased, a rate of R-13B1 is increased, resulting in that the highest capability can be attained. In turn, in case that a detected frequency is lower than a first set frequency and higher than a second set frequency, the four-way valve 25 is returned back to its non-energized state and then if the electromagnetic opening or closing valve 28 is opened, the refrigerant in the main circuit becomes equal to an initial filling rate.

摘要： PURPOSE:To enable the ratio of composition of coolant to be varied by a method wherein a mixture of mixed coolants of several types and cooling oil and the like are passed through an oil separator and then through a function film facilitating a specified coolant within the mixed coolant. CONSTITUTION:An aezotropic mixture of coolants of R-22 and R-13B1 containing oil component supplied from a mixture supplying pipe 2 is cleared of most of the oil components through an oil separator 1. The mixed coolant of which oil components are removed is flowed into a high pressure coolant inlet pipe 105 of a separator 101 and then enters the separator 101. R-22 which may easily pass through a function film 103 is discharged from a passed coolant outlet pipe 107. In turn, R-13B1 which may not easily be passed through the function film 103 is discharged through a high pressure coolant outlet pipe 106, Oil accumulated at the oil separator 1 is discharged from an oil discharging pipe 3 through a metering device 4. Accordingly, as the aezotropic mixture of coolants B-22 and R-13B1 containing oil constituents, a coolant having a high ratio of composition of R-13B1 higher than that of a high pressure coolant outlet pipe 106 can be attained, and in turn a coolant having a higher ratio of R-22 than that of a passing coolant outlet pipe 107 can be attained.

摘要： PURPOSE: To adopt a defrosting circuit as a combined use by connecting a refrigerant separator having a functional film for facilitating a passage of a specific type of a refrigerant between a discharge side of a compressor and an inlet of an evaporator, thereby variably constituting the refrigerant of a main circuit. CONSTITUTION: A refrigerant vapor compressed by a compressor 11 is cooled to be liquefied by a condenser 12. When solenoid valves 16, 17 are closed, it is stayed in a separator 101, pipings 105, 106, 107 and a reservoir 15. When the valve 17 is opened from the above state, branched refrigerant is fed to the separator 101, R-22 which is easily passed through a functional film 103 is returned to an inlet of an evaporator 14 via the valve 17. Meanwhile, R-13B1 which is scarcely passed through the film 103 is cooled to be liquefied by a cooler 18, and stored in the reservoir 15. Accordingly, in the case that a refrigerant separator 19 is connected between the discharge side of the compressor 11 and the inlet of the evaporator 14 to defrost the evaporator 14, when the valve 16 is opened, high pressure discharge refrigerant is fed into the evaporator 14, and hence it can be used also as a defrosting circuit.
