Abstract

The invention provides an absorption heat pump circulating system. The absorption heat pump circulating system adaptively changes among a single-effect mode, a 1.n-stage mode and a two-stage mode according to the temperature of a heat source. The absorption heat pump circulating system comprises a second solution loop with absorption generation heat exchange and a first solution loop. Cold generated by the second solution loop of absorption generation heat exchange is used for cooling a first absorber of the first solution loop. The temperature overlapping range of absorption generation heat exchange is determined by the temperature of the heat source. When the temperature overlapping range covers the whole generation process, the single-effect heat pump working mode is circulated; when the temperature overlapping range is zero, the two-stage heat pump working mode is circulated; and under other conditions, the 1.n-stage heat pump working mode is circulated. According to the absorption heat pump circulating system, the output temperature range of an absorption heat pump can be widened, the optimal system efficiency can be guaranteed under different output temperatures, and a preferred embodiment is provided for a low-grade heat source drive heat pump system.

Description

technical field [0001] The invention relates to a heat pump system, in particular to an absorption heat pump circulation system driven by a low-grade heat source. Background technique [0002] Energy and environmental issues are one of the two major problems plaguing the current human society. For example, the coal-fired heating system currently used in most parts of my country not only consumes a large amount of fossil energy, but also the emissions produced by coal combustion are also one of the important reasons for the haze weather. If an air-conditioning system is used for heating, it is possible to use refrigerants that cause ozone layer depletion and greenhouse effects as working fluids, and consume a lot of electric energy. [0003] Absorption heat pump and refrigeration technology can use heat input to obtain heat or cooling output. The heat source can come from gas combustion, industrial waste heat, internal combustion engine jacket water waste heat or solar steam...
