<p><P>PROBLEM TO BE SOLVED: To provide an air-conditioning system properly controlling heater energization for preventing liquid compression at compressor starting even if ambient temperatures vary according to the places where outdoor units are installed, in regard to an air-conditioning system comprised by connecting a plurality of outdoor units. <P>SOLUTION: The outdoor units 1a, 1b equipped with compressors 3a, 3b and outdoor heat exchangers 7a, 7b are respectively equipped with compressor preheating devices 10a, 10b for heating the compressors, and detecting means 15a, 15b for detecting values relevant to the internal or external temperature of the outdoor units. A preheating device control means 14 is provided to control so as to energize a compressor preheating device equipped in an outdoor unit of a side with a lower detection value of the plurality of detecting means. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
