摘要： PROBLEM TO BE SOLVED: To provide an air conditioner which can prevent a stain, etc., from occurring in an attic space, by preventing the dew condensation in a communication pipe arranged in the attic space or the like. SOLUTION: At cooling operation, temperature sensors 23A-23D arranged on outdoor unit side of connection pipes 11A-11D and 12A-12D detect the temperature of the refrigerant flowing to the suction side of the compressor 1 of an outdoor unit from the indoor heat exchangers 6A-6D of an indoor unit. Then, this air conditioner corrects the aperture of electric expansion valves 5A-5D by an electric expansion valve aperture correction part 10b so that the temperature of the refrigerant flowing from the indoor heat exchangers 6A-6D to the suction side of the compressor 1 of the outdoor unit may be kept to 8 deg.C or higher, based on the temperature of the refrigerant detected from the temperature sensors 23A-23D.

摘要： PROBLEM TO BE SOLVED: To provide a multiple type air conditioner capable of securely Improving air conditioning capability of an indoor machine of a priority room even when an indoor machine of another room other than the priority room is running. SOLUTION: A preference room selection section 5a selects any one among a plurality of indoor machines 2 to 3. An operation mode set section 5b sets to another indoor machine the same operation mode as that of the indoor machine selected by the preference room selection section 5a. An air conditioning capability control section 5c increases the amount of blowoff air from the indoor machine selected by the preference room selection section 5a and further increases operation frequency of a compressor of an outdoor machine 1. Further, when there are increased the amount of blowoff air of the indoor machine preferentially selected by the air conditioning capability control section 5c and the operation frequency of the compressor of the outdoor machine 1, a set temperature alteration section 5d alters set temperature of thermostat-off such that another indoor machine is likely to undergo thermostat-off.

摘要： PROBLEM TO BE SOLVED: To improve the rapid heating properties by considering the previous starting state by providing the opening of a motor-driven expansion valve at the time of starting by using the corrected opening stored in a previous starting information memory. SOLUTION: When the starting operation is conducted at the time of heating an air conditioner, the corrected opening of the opening of a motor driven expansion valve 4 is so set as to accelerate the rising at the time of next starting based on the state of the conditioner at the time of starting by a corrected opening setter 14, and stored in a previous starting information memory 15. After such, at the time of next starting, the opening of the valve 4 is set by using the corrected opening stored in the memory 15 by a motor driven expansion valve opening setter 11. Accordingly, the rising at the time of next starting is expedited. Thus, the rapid heating properties at the time of starting can be improved.

摘要： PURPOSE:To keep reliability of an indoor unit by stopping a compressor of an outdoor unit when the temperature of an indoor unit heat exchanger of the indoor unit exceeds a predetermined threshold value. CONSTITUTION:A plurality of indoor units X, X' which store different threshold values in memory means 44 can be selected in response to the number of connectable indoor units A. A temperature of an indoor heat exchanger 18 of the unit A is detected by means of a temperature sensor 31, and when the temperature exceeds a predetermined threshold value, a compressor 1 of the unit X is, for example, stopped by a protective controller 43. Thus, even if the number of the units A to be connected is altered without adding special protective function at the units X, X' side, similar reliability can be obtained.

摘要： PURPOSE:To surely detect the lock of a motor at the time of a start and during operation. CONSTITUTION:A compressor 1 is judged to have a defective start, i.e., to be kept in the lock state, and its operation is stopped when the following relation exists: #>=P>P2-P1, where P1 is the pressure value of a pressure sensor 41 at the time and prior to the start of the compressor 1, P2 is the pressure value when a certain time elapses after a start command, and DELTAP is the difference pressure set in advance. The lock of the compressor 1 at the time of the start can be detected in the whole area, and the seizure of a motor 42 can be prevented. The lock is detected during operation in consideration of the increase of the input current and the reduction of the pressure additionally.
