Inventor: MATSUMOTO SHINICHIRO
IPC: F24F11/02
Filed: 1987-10-07
Abstract: PURPOSE:To perform a positive detection of frost and perform a highly reliable defrosting control by a method wherein a temperature of coolant gas at an over-heated region is detected at an inlet pipe of an indoor heat exchanger, its correction is carried out in response to an amount of indoor air. CONSTITUTION:A heating operation is kept from a starting of heating operation for T1 time with a timer. As a compressor 1 is operated continuously for T2 time with the timer, the timer of T3 is set. As this timer is set for its counting, an amount of air is discriminated and a reading of a temperature of a pipe is read by a pipe temperature detecting element 6 in response to this amount of air. When the compressor 1 is being operated, a temperature of an inlet pipe is lower than a predetermined pipe temperature in response to each of amounts of air and a time T3 elapses, a defrosting operation is started. Accordingly, its configuration is quite simple, and a discrimination whether the coolant has a sufficient amount of carolie to perform a heating operation is carried out at an inlet side of an indoor heat exchanger, resulting in that a presence or a non-presence of an actual heating capability can be positively judged to perform a defrosting operation.
