摘要： PROBLEM TO BE SOLVED: To provide a control device of an air conditioner, preventing unnecessary breaker operation. SOLUTION: This control device 4 is a control device of the air conditioner 1 loaded with a variable displacement inverter compressor 11, and provided with a micro-computer 5. The micro-computer 4 controls the air conditioner 1 based upon the refrigerant state of a refrigerant circuit 10 including the inverter compressor 11. The micro-computer 5 computes an estimated value of a total consumption current in the air conditioner 1 in the case of raising the operational frequency in raising the operational frequency of the inverter compressor 11, and the estimated value and a preset total consumption current upper limit value are compared to determine permission or non-permission to raise the operational frequency.

摘要： PROBLEM TO BE SOLVED: To prevent dew condensation in an air conditioner including a plurality of refrigerant circuit systems, and constituted to allow the air to be sucked, passed through evaporators corresponding to the refrigerant circuit systems, then converge and blow out into a room. SOLUTION: This air conditioner includes the plurality of steam compression type refrigerant circuit systems respectively having a compressor, a cooler, an expansion mechanism and the evaporator, the evaporators are received corresponding to the refrigerant circuit systems, the air is sucked and passed through the evaporators corresponding to the refrigerant circuit systems, and then the air is converged to blow out into the room. Evaporation temperature equalization control is performed to control devices constituting each refrigerant circuit system so that evaporation temperature difference as temperature difference between the evaporation temperatures in the refrigerant circuit systems is not over a threshold evaporation temperature difference.

摘要： PROBLEM TO BE SOLVED: To keep a high pressure at a threshold value in all of refrigerant circuit systems in an air conditioner including the plurality of refrigerant circuit systems, and allowing an air distribution fan to be shared by condensers individually corresponding to the refrigerant circuit systems. SOLUTION: Each refrigerant circuit system of this air conditioner is provided with a condenser bypass circuit capable of bypassing a refrigerant distributed from a compressor to the condenser. In this air conditioner, an opening of an bypass electric valve constituting each condenser bypass circuit is controlled to keep high pressure in each refrigerant circuit system at threshold high pressure, and an air volume of the air distribution fan is controlled to be reduced when the high pressure in the refrigerant circuit system having the bypass electric value reaching control upper limit among the plurality of refrigerant circuit systems, is lower than the threshold high pressure.

摘要： PROBLEM TO BE SOLVED: To permit stabilized operation by releasing optimally high-pressure protection control operation. SOLUTION: In a refrigerating apparatus, effecting high-pressure protection control narrowing an operation range by setting the upper limit value fmax of an operating frequency by a frequency control mechanism after a high pressure Ph, detected by a high-pressure detecting means, has exceeded a prescribed pressure Phs1, the regulation of operation by the upper limit frequency fmax is released, based on the conditional change of discharging refrigerant of a compressor 1, after continuing the high-pressure protection control operation for a prescribed time t1 whereby rushing again into the high-pressure protection control operation, immediately after releasing the regulation of operation by the upper limit frequency fmax is eliminated.

摘要： PROBLEM TO BE SOLVED: To provide a heater controller for compressor which can prevent refrigerant from being mixed with lubricating oil in a compressor and refrigerant from being gathered in a compression chamber, reduce consuming power more than conventional systems, and can increase the service life of a heater itself and electric parts. SOLUTION: This controller is provided with an outside air temperature sensor 32 for detecting atmospheric temperature on the side where a compressor 4 is installed out of exterior devices or interior devices. A control part 11 compares the temperature T1 detected by the outside air temperature sensor 32 with a fixed reference value (for example, 25 deg.C), and permits a heater 23 to be energized when the temperature T1 detected by the outside air temperature sensor 32 is less than the reference value, and prohibits the heater 23 from being energized when the temperature T1 detected by the outside air temperature sensor 32 is the reference value or higher.

摘要： PROBLEM TO BE SOLVED: To detect negative phase connection of a motor connected to a three-phase alternating power source in an air conditioner while minimizing addition of electric circuit components such as a negative phase protection relay. SOLUTION: This negative phase detecting device comprises the motor and a negative phase determining means. The motor is connected with the three-phase alternating power source, and drives a motor-driven device as a part of component devices of the air conditioner. The negative phase determining means determines whether the motor is connected with the three-phase alternating power source in negative phase or not base on a refrigerant flowing in a refrigerant circuit of the air conditioner or operational state quantity of the component device.
