METHOD OF FREEZING WITH THE AID OF A COOLING ARRANGEMENT HAVING A SECONDARY REFRIGERATION SYSTEM AND PRIMARY ABSORPTION REFRIGERATION APPARATUS ASSOCIATED THEREWITH

摘要

A freezer in which goods are frozen and already frozen goods are stored, such freezer embodying primary absorption refrigeration apparatus and a secondary refrigeration system associated therewith. The evaporator of the primary absorption refrigeration apparatus has a first part operable at a low temperature and a second part operable at a higher temperature. The second part of the primary evaporator operable at the higher temperature is employed to freeze goods. The secondary refrigeraton system contains a heat transfer fluid and has a condensation portion in heat exchange relation with the first part of the primary evaporator operable at the low temperature and an evaporation portion employed to maintain frozen already frozen goods.
