A refrigerated cabinet has thermally insulated walls within which is a lining comprising a sealed chamber through which a prefrozen refrigerant is circulated by a time controlled compressor

摘要

The insulated (3) housing (2) forms a chamber (1) for storing chilled products and a sealed wall lining (4) has circulation channels (5) filled with a frozen salt solution which is circulated by a compressor (6) during low tariff hours, switched by a time clock (7). The interior temperature is monitored by a thermal sensor (8) and the cooling chamber by another (9) to avoid icing.
