<P>PROBLEM TO BE SOLVED: To control a compressor in accordance with the disturbance of the load of an air conditioning. <P>SOLUTION: A constant setting device 10 is adapted to a multi-type air conditioner 1 in which a plurality of indoor units 3a, 3b are connected parallel with each other to one outdoor unit 2 having a compressor 21 and sets a control constant concerning the pressure control of the compressor 21. The constant setting device 10 includes: a calculation part 11 for calculating a first control constant being a control constant calculated according to a change in an aimed pressure value of the compressor 21 and a second control constant being a control constant calculated according to the total operation capacity of the operated indoor units 3a, 3b connected to the outdoor unit 2; and a the-number-of-revolution determination part 16 for determining the number of the revolution of the compressor 21 based on the second control constant in the normal operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
