摘要： PROBLEM TO BE SOLVED: To provide a controller for an air conditioner by which the number of times of starts and stops of a compressor can be minimized without sacrificing a temperature controllability required for load. SOLUTION: A controller for an air conditioner comprises a stop command means (steps S4 and S5) for stooping a compressor when the temperature of outlet air is lower than a setting value, a storing means (S5, 16b) for storing the temperature ti1 of inlet air when the stop command means stops the compressor, and a start command means (S6, S3) for starting the compressor when the temperature of the inlet air rises by a prescribed value higher than the stored temperature ti1. The inlet air reflects the cooling state of load more faithfully than the outlet air in accordance with a computer or the like. Further, the lifting slope of temperature of the inlet air after the compressor stops is smaller than that of the outlet air after the compressor stops.

摘要： PROBLEM TO BE SOLVED: To issue properly an alarm accompanying an automatic restarting control, in accordance with a change in the form of maintenance, and thereby to lighten a burden on personnel for maintenance by providing a control means which sets a prescribed number of times variably on the basis of a time count of a timer means for counting day and hours. SOLUTION: A control means which sets a prescribed number of times variably according to a time zone of workday daytime and time zones of workday nighttime and a holiday on the basis of time count of a timer means is provided. The hottest point is determined by a function using a detected temperature and an operating frequency and is compared with a standard set value and thereby abnormality of an excess of the temperature of a discharge pipe is detected. In the time zone of workday daytime, an irregular stop and restarting due to the abnormality are allowed until they occur five times, but when they occur six times, an alarm is issued by a monitoring device 61. In the time zones of workday nighttime and a holiday, however, the irregular stop and the restarting are allowed until they occur 10 times, In the form of maintenance wherein the number of personnel for maintenance stationed in a remote monitoring center 60 is few, accordingly, the rate of issuance of the alarm can be lessened.

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 realize the enlargement of the variable range from the standard air capacity to the low air capacity side thus making a floor installation type air conditioner easily cope with the alteration from the water cooling type to the air cooling type, in the air conditioner which supplies the blown-off air to a room to be air-conditioned by way of a duct. SOLUTION: This air conditioner is constructed such that a heat exchanger 1 and a fan 12 are accommodated in a casing 2 and blown-off air is supplied to a room to be air- conditioned by way of a duct 5. In this case, the casing 2 substantially has the same configuration as a casing of a floor installation type water cooling type air conditioner having a specific standard heating and cooling capacity. The heat exchanger 11 has the heat exchanging capacity larger than the heat exchanging capacity of a heat exchanger 11 applied to a floor installation type air cooling type air conditioner having a specific capacity larger than the specific standard heating and cooling capacity of the above-mentioned water cooling type air conditioner. Furthermore, a fan 12 which has an air capacity and approximately similar to an air capacity corresponding to the specific standard heating and cooling capacity of the water cooling type device is used. Due to such a construction, the alteration of the floor installation type air conditioner from the water cooling type to the air cooling type can be carried out while maintaining the same capacity and same installation site and the same duct after the alteration.

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 prolong the time to an abnormal stop as long as possible by distinguishing a refrigerant deficiency state from an operating state in which an atmospheric temperature is low and deciding it. SOLUTION: The air conditioner has a refrigerant circuit A having a compressor 1, a condenser 2, an expansion valve 3 and an evaporator 4 attached with an indoor fan 6 sequentially connected. The air conditioner comprises a deciding means for deciding a refrigerant deficiency state in which a refrigerant amount in the circuit A is insufficient, when the valve 3 is fully opened and a pressure difference between high and low pressures in the circuit A becomes a predetermined value or more; and a control means for controlling to lower the discharge temperature of the compressor 1 when the refrigerant deficiency state is decided by the deciding means to fully open the valve 3, and to control to lower the discharge temperature of the compressor 1 when it is decided that the valve 3 is fully opened and the pressure difference between the high and low pressures becomes the value or more (that is, the deficiency state is decided). The control to lower the discharge temperature of the compressor 1 is executed, thereby suppressing the rise of the temperature generated due to the deficiency operation.
