摘要： PROBLEM TO BE SOLVED: To provide an air conditioner in which a room temperature control can be improved and the life of a compressor can be increased. SOLUTION: An air conditioner is provided with a refrigerant circuit in which a compressor 1, an outdoor heat exchanger 2, a motor-operated valve 3 and an indoor heat exchanger 4 are connected together in a ring shape. A room temperature discriminating part 10c discriminates whether room temperature detected by a room temperature sensor 6 is lower than set room temperature or not. When the room temperature discriminating part 10c discriminates that the room temperature is lower than the set room temperature during the operation of the compressor 1 at minimum operating frequency, an air quantity control part 10b of an air supply fan reduces the air volume of an air supply fan 5 for the indoor heat exchanger 4 in accordance with a command from an air volume decrease command part 10d. Accordingly, the number of times of starts and stops of the compressor 1 can be decreased.

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 control air volume of an outdoor fan so as to become maximum COP responsive to an outdoor temperature. SOLUTION: A storage unit 9 stores a cooling capacity table 10 representing an air volume exhibiting maximum capacity for an outdoor temperature and a COP table 11 representing an air volume exhibiting maximum COP for the outdoor temperature. An air volume switching control unit 8 obtains an air volume of an outdoor fan 5 becoming the maximum COP at the outdoor temperature by using the table 11, and outputs a control signal responsive to the volume to a fan control unit 12. Thus, the volume of the fan 5 is normally COP- controlled to obtain energy conservation. On the other hand, if a cooling capacity is insufficient, the volume of the fan 5 becoming maximum cooling capacity at the outdoor temperature is obtained by using the table 10, and a control signal responsive to the volume is output to the unit 12. In this manner, cooling capacity insufficiency is exactly dealt with.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner in which an abnormal stop of operation can be prevented during cooling operation even of the outdoor device are densely deployed. SOLUTION: This air conditioner is provided with a refrigerant circuit in which a compressor 1, an outdoor heat exchanger 2, an expansion means 3 and an indoor heat exchanger are annulaly connected and an outdoor fan 5 for the outdoor heat exchanger 2. When a judgment is made to start operation, by operation starting discriminating section 11 the outdoor fan 5 is operated through an outdoor fan control section 12 and then a timer 14 starts time counting of a predetermined time. Then, after the time counting with the timer 14 is completed, the compressor 1 is energized through a compressor control section 15. Since the outdoor heat exchanger 2 is cooled with the outdoor fan 5 before the compressor 1 is energized, a discharging gas temperature of the compressor 1 can be restricted in its increasing and abnormal stopping caused by the abnormal high temperature of the discharged gas can be prevented.

摘要： PROBLEM TO BE SOLVED: To obtain excellent comfortable property in an air conditioner whose object is unspecified public, by a method wherein a final objective temperature is determined based on a temperature difference between an objective room temperature determined on the thermal sense of human, and the required temperature of a user determined on the demand of the user. SOLUTION: A temperature control device Z controls an operation of a refrigerant circuit equipped with a compressor 7, a motor-driven valve 8 and the like while the control device Z is equipped with an operation circuit 4. A present outdoor temperature and a present indoor suction air temperature are inputted from an outdoor temperature sensor 1 and an indoor temperature sensor 2 into the operation circuit 4 while a user demanding temperature is inputted into the operation circuit 4 from a remote controller 3. On the other hand, the user demanding temperature is indicated in the remote controller 3. The outdoor temperature, the indoor temperature and the user demanding temperature are received in the operation circuit 4 to obtain an objective room temperature while considering a PMV index and operate the final objective temperature based on a comparison between the objective room temperature and the user demanding temperature.
