Problems solved by technology

However, when solar energy is used as the driving heat source, the absorption chiller cannot operate around the clock due to the intermittent and unstable nature of solar energy.
Usually, the traditional cooling capacity adjustment of absorption refrigeration is mainly realized by changing the temperature of the heat source or the fluid flow of the heat source. The cooling capacity adjustment is limited

Abstract

The invention relates to an absorption heat pump system with variable concentration capacity regulation of mixed working fluid, comprising: an energy storage device, a solution storage tank, a condenser, a throttling device, a cooler, an evaporator, a high-pressure storage tank, a low-pressure storage tank, and rectification The system stores and releases the potential of solar energy and solution through the energy storage device and the solution storage tank, and combines the variable concentration capacity adjustment method to make the air conditioning system meet the working needs of the day and night. The invention can overcome the shortcomings of intermittent and unstable solar energy utilization in the existing solar absorption refrigeration technology, realize the all-weather operation of the solar absorption refrigeration technology, improve the refrigeration coefficient, and have the advantages of high efficiency, energy saving, stable and reliable performance, and the like.

Description

technical field [0001] The invention relates to an absorption heat pump system driven by solar energy, in particular to an absorption heat pump system with variable concentration capacity adjustment of mixed working fluid with energy storage function. Background technique [0002] Absorption refrigeration can be driven by low-grade thermal energy such as solar energy, and uses environmentally friendly working fluids as refrigerants, which has the advantages of energy saving and environmental protection. However, when solar energy is used as the driving heat source, the absorption chiller cannot operate around the clock due to the intermittent nature and instability of solar energy. Usually, the traditional cooling capacity adjustment of absorption refrigeration is mainly realized by changing the temperature of the heat source or the fluid flow of the heat source. The cooling capacity adjustment is limited. In order to solve the above problems, the variable concentration ca...
