Space-heating in supermarkets - using waste heat from food-storage refrigeration plant, with flap valve and fan

摘要

Space-heating air circulation system for supermarkets with food sections, large slaughterhouses, or cold stores, uses the calorific power blown out into the air from the refrigeration plant, as a waste product, in the form of thermodynamically positively heated ventilation air, with ventilating flaps that can varied as required. Preferably the heated ventilation air from the refrigeration plants is forced as required by a fan through its space-heating circulation. More particular the apparatus has changeover ventilating flaps and a fan between the cold plant chamber and the space-heating area.
