摘要：PURPOSE:To perform a defrosting operation in sequence for each of the lines and restrict a reduction in capacity refrigeration by a method wherein the operation is controlled by a stored microcomputer in such a way as a defrosting operation instruction signal is forcedly outputted in sequence under a desired order. CONSTITUTION:When a forced defrosting operation instruction switch 20 is manually operated, timer times t1-t3 are measured by each of the timer time setting means 25-27. Every time the measurement of each of the timer times t1-t3 is completed, the measurement of other timer times is temporarily stopped by temporary stop means 31-33 and the defrosting operation instruction signal is forcedly outputted from the corresponding deicers 10-12 for a desired period of time, for example, 10min on the basis of the forced defrosting operation instruction signal output means 28-30, thereby the defrosting operation correspondingto each of the coolant circulation systems A-C is carried out in sequence in the order of the first, second and third order for each of the systems. Therefore, a substantial reduction in refrigerating capacity caused by a defrosting operation is restricted, a low cost and small-sized equipment can be attained.
