<p><P>PROBLEM TO BE SOLVED: To solve a problem that, in a conventional multi-chamber type air conditioner, a relatively expensive pressure detector is used as a capacity control input of a compressor and excessive heating is effected under low load because a pressure setting value is determined according to the operation-on horsepower irrespective of the load of an indoor unit. <P>SOLUTION: The condensation temperature of refrigerating cycle can be detected at the maximum temperature value of an indoor heat exchanger in the connected indoor unit even without using the pressure detector. The heating performance can be ensured by correcting the frequency of the compressor upward until the target value is reached, when the condensation temperature is lower than a specified target condensation temperature threshold value. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
