Abstract

A method of continuous air cooling of the medium-temperature gastronomic refrigerating displays of shop equipment with the air cooler consisting of two independent evaporators (7,9) have been proposed. The air cooling is being effected with both evaporators (7,9) simultaneously whereas defrosting of evaporators is being effected by turns so that the defrosting cycle of one of the evaporators (7,9) is effected with a time shift relative to another evaporator by ½ of the defrosting period. During the entire defrosting period of one of the evaporators (7,9) the refrigerant supply to the other (cooling) evaporator is being effected continuously irrespective of the preset temperature control program.
