Novel circulation manner large-temperature-difference heat exchange unit

Abstract

The invention discloses a novel circulation manner large-temperature-difference heat exchange unit. The novel circulation manner large-temperature-difference heat exchange unit comprises a generator,a condenser, an evaporator set, an absorber set and a water-water plate heat exchanger. The generator is sequentially connected with a primary network water inlet, the water-water plate heat exchanger, the evaporator set and a primary network water outlet. The water-water plate heat exchanger communicates with a secondary network water inlet and a secondary network water outlet through a secondarynetwork water pipeline, and the secondary network water inlet is sequentially connected with the absorber set, the condenser and the secondary network water outlet through a pipeline. The absorber set is connected with a first solution pipeline, the first solution pipeline communicates with the generator after passing through a solution heat exchanger, the generator communicates with a second solution pipeline, and the second solution pipeline is connected with the top of the absorber set after passing through the solution heat exchanger. The bottom of the condenser communicates with a refrigerant pipeline communicating with the evaporator set, and the bottom of the evaporator set is connected with a refrigerant pump and an evaporator set spraying device through the refrigerant pipeline.The novel circulation manner large-temperature-difference heat exchange unit is simple in structure, small in heat exchange area and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a new circulation mode large temperature difference heat exchange unit. Background technique [0002] Lithium bromide unit, also known as lithium bromide absorption heat pump unit or large temperature difference heating unit, is a kind of equipment that uses circulating water in the heating network as the heat source, water as the refrigerant, and lithium bromide aqueous solution as the absorbent to prepare hot water for heating in a vacuum state. , The traditional lithium bromide unit has a single steaming single suction type and a double steaming double suction type, with complex structure, large heat transfer area and low heat transfer efficiency. Contents of the invention [0003] The object of the present invention is to provide a new type of circulation mode large temperature difference heat exchange unit to solve the problems of the above-mentioned prior art, with ...
