Abstract

PURPOSE:To enable execution constant speed operation and to enable confirmation of rated performance stipulated as JIS standard, by a method wherein, during cooling, when a room temperature set value is less than a specified temprature, maximum drive frequency is controlled to rated value prevailing during cooling, and during heating, when a room temperature set value exceeds the specified temperature, maximum drive frequency is limited to rated value prevailing during heating. CONSTITUTION:A volume varying type compressor 3, a 4-way switching valve 4, an outdoor heat exchanger 5, and a pressure reducing device 7 are contained in an outdoor 1, and are connected to an indoor heat exchanger 8 contained in an indoor unit 2 to form a freezing cycle. When cooling or heating operation is started, a volume varying compressor 3 is driven by converting the frequency of a commercial source 15 into a given frequency in response to a temprature difference between a room temperature and a room temperature set value set by a room temperature set switch 14. When, during cooling, a room temperature set value is below 20 deg.C, maximum driven frequency is limited to a rated value, and when, during heating, a room temperature set value exceeds 30 deg.C, controll is effected so that maximum drive frequency is limited to a rated value available during heating, and therefore, constant speed operation under standard temperature conditions stipulated as JIS standard can be attained without any particular switches.
