AIR HEAT ENERGY DEVELOPMENT AND APPLICATION METHOD AND HEAT EXCHANGE APPARATUS, AS WELL AS REFRIGERATION APPARATUS WASTE HEAT RECOVERY METHOD

摘要

An air heat energy (143) development and application method and heat exchange apparatus thereof, the air heat energy (143) development and application method utilizes a liquid medium to exchange heat via a heat-exchange air heat energy application apparatus, and coverts the air heat energy (143) into liquid-state heat energy or ice-state heat energy for utilization; the air heat energy (143) passes through the fins (135) of a primary heat exchanger (1), is converted into liquid-state low-temperature heat energy by the liquid medium in a group of tubes (134), and then passes through a circulating pump (37) and a tube network (64), and flows into a freezer heat exchanger (40) of a heat-exchange freezer (21) to freeze the water in an energy storage tank (82) into ice so as to provide a cold source for the freezer compartment (86). Also disclosed is a refrigeration apparatus waste heat recovery method, using a liquid medium in heat exchange mode to convert the waste heat into liquid-state heat energy or ice-state heat energy for utilization.
