Problems solved by technology

[0002] The purpose of refrigeration can be achieved by using the endothermic effect of chemical refrigerants dissolved in water. However, due to the limitation of continuous refrigeration, chemical refrigerants are currently mainly used for intermittent refrigeration in the field, which cannot meet the cooling requirements of buildings. Building heating cannot be realized, and the application is very limited

Embodiment Construction

[0009] The system is mainly composed of dissolver, crystallizer, generator, condenser, heat exchanger and solar collector. Workflow includes solution circulation and water vapor circulation:

[0010] Solution circulation:

[0011] 1. In the dissolver (3), the chemical refrigerant fully contacts with the water that enters the dissolver (3) through the heat exchanger (6) and the throttle valve (8), dissolves and absorbs heat to produce cooling capacity, and becomes a concentration of z 1 dilute refrigerant solution;

[0012] 2. The concentration is ζ 1 The dilute refrigerant solution passes through the solution circulation pump (11), passes through the heat exchanger (6) and the solution heat exchanger (7) and successively matches with the hot water from the condenser (2) and the concentration of the hot water from the generator (1). for ζ 2 The concentrated refrigerant solution is heat-exchanged, then enters the generator (1), and is generated by solar heat collector (5); ...

Abstract

The invention relates to a solar-driven chemical refrigerant dissolution crystallization cooling and heating combination system. The system uses a solar heat collector for collecting heat of chemical refrigerant solution in a generator, and crystallizes in a crystallizer to realize regeneration of chemical refrigerant. Vapor generated in the generator enters a dissolver after condensation, heat exchange and throttling to fully contact with the regenerated refrigerant for dissolving to realize continuous refrigeration; and cooling water is heated by serial connection of the crystallizer and the condenser to realize continuous heating so as to realize the building heat and cold combined supply.

Description

technical field [0001] The invention relates to a new building cooling and heating system, in particular to a chemical refrigerant dissolution and crystallization type cooling and heating system driven by solar energy. Background technique [0002] The purpose of refrigeration can be achieved by using the endothermic effect of chemical refrigerants dissolved in water. However, due to the limitation of continuous refrigeration, chemical refrigerants are currently mainly used for intermittent refrigeration in the field, which cannot meet the cooling requirements of buildings. Building heating cannot be realized, and the application is very limited. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a solar-driven chemical refrigerant dissolution and crystallization system that can continuously refrigerate and supply domestic hot water, so as to realize the combined cooling and heating of buildings. [0004] In...
