Sun-driven adsorption type combined cooling, heating, power and water production system for desert and method thereof

Abstract

The sun-driven adsorption type combined cooling, heating, power and water production system comprises a condenser, a central heat exchanger, an evaporator and a plurality of adsorption beds, each adsorption bed comprises a first heat exchange pipe, and a second heat exchange pipe correspondingly communicated with the first heat exchange pipe is arranged in the central heat exchanger; the central heat exchanger is used for externally supplying heat to form a heat supply module; a photovoltaic cover on the surface of the adsorption bed absorbs sunlight and outputs electric energy to form a power generation module; a steam outlet of the adsorption bed is communicated with a steam inlet of the condenser, the condenser is used for condensing water vapor into liquid water, and a first water outlet of the condenser is connected with the water collecting tank to form a water producing module; a second water outlet of the condenser is communicated with a water inlet of the evaporator, an expansion valve is arranged on a connecting pipeline, and a water outlet of the evaporator is communicated with a water inlet of the adsorption bed to form a refrigeration module. Multiple-effect output is achieved through the same set of system driven by solar energy and the method thereof, so that the living requirements of desert residents for cooling, heating, electricity and water are met.

Description

technical field [0001] The invention belongs to the technical field of new energy utilization, and in particular relates to a solar-driven adsorption cooling-heating-electricity-water cogeneration system for deserts and a method thereof. Background technique [0002] The depletion of fossil energy and the deterioration of environmental pollution are the key challenges for the comfortable survival of human beings and the sustainable development of society. In order to meet the rapid economic development, improve the comfort of the living environment, and effectively deal with climate change, it depends on the development of advanced new energy utilization technologies. In this context, the solar-driven adsorption energy technology has attracted extensive attention from scholars at home and abroad due to its advantages of significant energy saving and multi-effect output effects. The notable feature of this technology is the use of the adsorption heat effect of the adsorbent o...

Problems solved by technology

For example, Professor Anthony Paul Roskilly published "Experimental investigation on an innovative resorption system for energy storage and upgrade" in Energy Conversion and Management (138 (2017) 651-658) and Professor L.L. Vasiliev published in Applied Thermal Engineering (38 (2012) 124- 130) published "Three adsorbers solar cooler with composite sorbentbed and heat pipe thermal control", this research has good refrigeration and heat storage effect, but its shortcoming is that it cannot realize the function of water collection, and water resources are very important to desert residents. life is extremely important

Based on this, in terms of adsorption-type air water intake using hydraulic substances as adsorbates, Professor Ruzhu Wang of Shanghai Jiaotong University recently published "Ultrahigh solar-drivenatmospheric water production enabled by scalable Rapid-cycling waterharvester with vertically aligned nanocomposite sorbent" and "Water harvesting from air with metal-organic frameworks powered by natural sunlight" published by Professor Evelyn N. Wang of the Massachusetts Institute of Technology on Science (356 (2017) 430-434) both use Adsorption technology has achieved a better effect of air water intake, but it has not proposed a better technical solution in terms of multi-effect combined supply

In addition, Chinese patent application number: 201110121883.8 proposes a solar power-water cogeneration system, which has the functions of power generation and condensation water collection, but its shortcomings also lack the exploration of multi-effect output functions such as cooling and heating, and the improvement of desert The comfort of the living environment is also very urgent

[0004] However, no matter in the adsorption technology using water or ammonia as the adsorbate, the disclosed schemes fail to realize the cogeneration function of cooling, heating, electricity and water in the desert environment in the same system, and the residents living in the desert are very interested in cooling, heating, electricity and water. The need for water resources is extremely urgent
