Abstract
PURPOSE: To enable to indicate the exact defrosting timing by deciding the defrost start in comparing the pre-set value with the ratio of heating capacity under no-frost in corresponding to the outside air termperature during detecting time of heating operation to the actual heating capacity. Room temperature, outside temperature and refrigerant temperature or pressure are detected, and defrost-start-time is decided in comparing the pre-set value and the ratio of the pre-set heating capacity (no-frost period capacity) under the detect room temperature and outside temperature to the actual heating capacity (frosting period capacity).
