Description

technical field [0001] The invention relates to the technical field of solar power generation and heat pump systems, in particular to a solar auxiliary heat pump system integrating waste heat recovery and self-cleaning functions. Background technique [0002] Absorption heat pump is a circulation system that utilizes low-grade heat sources to pump heat from low-temperature heat sources to high-temperature heat sources. It is an effective device for recycling low-temperature potential heat and has dual functions of saving energy and protecting the environment. Absorption heat pumps can be divided into two categories: [0003] The first type is absorption heat pump, also known as heat-increasing heat pump, which uses a small amount of high-temperature heat source (such as steam, high-temperature hot water, and combustible gas combustion) as the driving heat source to generate a large amount of useful heat energy at medium temperature, and uses high-temperature heat energy to d...

Problems solved by technology

The system exchanges heat between the heated lithium bromide solution and the concentrated lithium bromide solution before entering the high-temperature generator, and preheats the dilute solution, which reduces the use of natural gas to a certain extent, but reduces the temperature of the dilute lithium bromide solution and reduces the absorption The efficiency of hot water preparation by the water heater, and the preheating effect is not obvious; the cooling tower for preparing cooling water in this system accounts for most of the power loss, which increases the operating cost of the system
