Separated solid-adsorption-type refrigerating system

Abstract

The invention relates to a separated solid-adsorption-type refrigerating system, which comprises a first adsorption unit, a second adsorption unit and a shell-and-pipe heat exchanger, wherein the first adsorption unit and the second adsorption unit are mutually communicated through a first pipeline and a second pipeline which are arranged in the shell-and-pipe heat exchanger. In the invention, when the first adsorption unit and the second adsorption unit alternatively carry out adsorption and desorption actions, the temperature of the first pipeline and the temperature of the second pipeline are reduced so as to realize the refrigeration effect, and further, the temperature of the water circulating in the shell-and-pipe heat exchanger can be reduced. In addition, because the shell-and-pipe heat exchanger does not need to be maintained under a vacuum environment for operation, the manufacturing cost of the separated solid-adsorption-type refrigerating system can be reduced; furthermore, the shell-and-pipe heat exchanger is mutually separated from the first adsorption unit and the second adsorption unit, so that the size of the whole system can be reduced.

Description

technical field [0001] The invention relates to a solid adsorption refrigeration system, in particular to a separated solid adsorption refrigeration system. Background technique [0002] In recent years, due to the destruction of the ozone layer, the greenhouse effect and other issues that have negatively affected the environment, countries around the world have begun to control refrigerants that emit greenhouse gases, and have developed many technologies that are both environmentally friendly and energy-saving. Among them, solid adsorption refrigeration technology has the advantages of clean and pollution-free, no external power supply required for the host, simple structure, long service life, no moving parts and noise, etc., and it can also be driven by waste heat (such as industrial waste heat, low-temperature heat sources such as solar energy) Therefore, it is considered to be an effective key technology that can take into account both energy saving and environmental pr...

Problems solved by technology

However, the current solid adsorption refrigeration system is limited by the selection of adsorbent materials and working fluids. Both adsorption and desorption must be carried out under vacuum pressure. Therefore, all components and connecting pipelines must meet the requirements of high pressure resistance, and the system The overall volume is extremely large

[0007] In addition, since the adsorption bed, evaporator and condenser all need to be integrated in the same vacuum chamber, the adsorption, desorption, evaporation and condensation also need to be carried out in the same pressure environment, even if the evaporator and condenser are integrated into the same heat exchange device, it is still unable to effectively reduce the volume of the solid adsorption refrigeration system

Furthermore, the existing conventional heat exchangers that integrate the functions of the evaporator and condenser are not specifically designed for the heat transfer characteristics of evaporation and condensation, so not only cannot the cooling performance be improved, but also the manufacturing cost of the system cannot be effectively reduced. Therefore, It has been unable to effectively apply the solid adsorption refrigeration system to the air conditioning system for a long time

[0008] It can be seen that the above-mentioned existing solid adsorption refrigeration system obviously still has inconvenience and defects in product structure, manufacturing method and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
