Abstract

The present invention relates to a kind of air-cooled water-cooled double-evaporator hot-water machine unit for recovering after heat of waste water. It is mainly characterized by that it has a refrigeration circulating loop formed from compressor, water-cooled condenser, air-cooled evaporator and water-cooled evaporator. Said invention also provides the working principle of said air-cooled water-cooled double-evaporator hot-water machine unit and its concrete operation method.

Description

technical field [0001] The invention relates to a combination system of heat supply, simultaneous heat supply and cooling supply, in particular to an air-cooled water-cooled double evaporator hot water unit for recovering waste heat from waste water. Background technique [0002] At present, in many bathing places, a large amount of hot water with a certain temperature is discharged as sewage. From the perspective of hygiene, this water does not have the value of reuse, but the heat contained in it has the value of reuse. Especially in winter, the temperature of the discharged water reaches 30°C, making full use of this heat can greatly save energy and reduce costs. Contents of the invention [0003] The object of the present invention is to provide an air-cooled and water-cooled double evaporator hot water unit in which two heat source sides are connected in series, one of which can absorb heat energy in waste hot water for heating. [0004] The technical solution of the...
