DEVICE FOR DEICING AN AIR-COOLER FOR THE REFRIGERATED SHOWCASE OF SHOP EQUIPMENT

摘要

The invention relates to refrigeration engineering, in particular to systems for deicing refrigerated showcases provided with direct cooling units, preferably to low-temperature refrigeration shop facilities with antifreezing heat carriers. The inventive device comprises a heat storage with an antifreezing heat carrier, a pump for circulating said antifreezing heat carrier and a recuperative heat exchanger which are connected to each other and elements for supplying heat to the heat exchange surface of a showcase evaporator, to the showcase bottom and to a drainage pipeline. The heat supply elements are embodied in the form of two sections, the first of which is arranged in the air-cooler evaporator and contacts the heat exchange surface thereof, whilst the second section is mounted in the showcase bottom near the drainage pipeline. The two sections being interconnected by means of the heat storage. Said device reduces a deicing time and energy consumption.
