Abstract
The utility model relates to a high temperature heat pump unit which directly extracts low-grade heat below 20 DEG C for outputting a heat source above 70 DEG C. Two groups of independent vapor compression refrigeration circulation systems are adopted in one single heat pump unit, and condensing heat of one group of the independent vapor compression refrigeration circulation systems is used as adsorbing heat for evaporation of the other group of the independent vapor compression refrigeration circulation systems. Furthermore, heat between the two groups of the independent compression refrigeration circulation systems is transferred by adopting an efficient compounded heat exchanger, thus improving the heat exchanging efficiency of the unit, decreasing heat transfer loss at intermediate links, and realizing stable and efficient working with long service life.
Description
Affiliated technical field
The utility model relates to a kind of high temperature heat pump unit that thermal source more than 70 ℃ can be provided, and especially can directly utilize the high temperature heat pump unit of tow taste heat below 20 ℃.
Background technology
At present, Chang Yong source pump can be divided into the plain edition source pump below 55 ℃, 55 ℃～70 ℃ middle high temperature heat pump unit and the high temperature heat pump unit more than 70 ℃ according to its heat source temperature that provides.But the high temperature heat pump unit mostly requires to work under the condition than the high-grade heat having more than 20 ℃, can't directly utilize the tow taste heat below 20 ℃.Even there are some high temperature heat pump units can directly utilize tow taste heat below 20 ℃, it all is the higher concept nature product of inefficiency fault rate mostly, but its practicality and generalization are relatively poor.
Summary of the invention
In order to overcome the deficiency that existing high temperature heat pump unit directly utilizes the tow taste heat below 20 ℃, the utility model provides a kind of twin-stage superhigh temperature source pump, not only can directly utilize the tow taste heat below 20 ℃, and the work of long-life that can stability and high efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: adopt two groups of independently Vapor Compression Refrigeration Cycle systems in the separate unit source pump, wherein one group condenser heat is realized the twin-stage temperature increase as the evaporation heat absorption usefulness of another group; And two groups independently the heat transmission between the Vapor Compression Refrigeration Cycle system adopt the efficient composite heat exchanger, improve set heat exchange efficient, the hot transmission loss of cutting down the number of intermediate links.First order refrigeration system is extracted heat and is provided 50 ℃～55 ℃ heat for second level refrigeration system from the tow taste heat below 20 ℃, the same stability and high efficiency with the plain edition source pump of first order refrigeration system.Second level refrigeration system is extracted 50 ℃～55 ℃ the heat that first order refrigeration system provides, the thermal source of output more than 70 ℃ by the efficient composite heat exchanger.Twin-stage promotes the suction and discharge pressure differential that temperature has reduced compressor, reduces fault rate and improves service life, and the leakage that reduces in the cold-producing medium compression process improves refrigerant compression efficient.
The beneficial effects of the utility model are: can directly utilize the thermal source of tow taste heat output more than 70 ℃ below 20 ℃, and the work of long-life that can stability and high efficiency.
