An absorption heat pump unit and a heating system for recovering waste heat from a low-temperature water source

Abstract

The invention discloses an absorption heat pump unit and a heat supply system for recovering waste heat from a low-temperature water source. The absorption heat pump unit (10) includes an evaporator (E), an absorber (A), a generator (G), a condenser (C) and a primary network water pipeline; the evaporator (E), the absorber (A), the generator The condenser (G) and the condenser (C) are sequentially connected through fluid pipelines to form a fluid closed circulation pipeline; the primary network water pipeline is connected to the heat exchange tube inside the absorber (A) to form a primary network water circulation pipeline. The absorption heat pump unit provided by the present invention is provided with a fluid closed circulation pipeline and a primary network water circulation pipeline, through which the fluid closed circulation pipeline heats the primary network water circulation pipeline, and the above absorption heat pump unit can make full use of the low High-grade heat energy saves resources while reducing heating costs and obtaining fresh water.

Description

technical field [0001] The invention relates to the field of heat supply, in particular to an absorption heat pump unit and a heat supply system for recovering waste heat from a low-temperature water source. Background technique [0002] Energy issues have become the focus of worldwide attention. The low-grade thermal energy in ocean water is a renewable energy with huge capacity, which has not been fully developed yet. my country's coastline is more than 30,000 kilometers long, and seawater in most waters is suitable as a cold and heat source for heat pump units, which provides a broad market for seawater source heat pump units, and has also been developed and applied to a certain extent in recent years. Seawater is highly corrosive to metals. In order to reduce the corrosiveness of seawater to heat pump units, the existing seawater source heat pump system is equipped with a detachable titanium plate heat exchanger between the unit and the seawater pumping well, and the sea...
