Problems solved by technology

Whether it is an adsorption refrigeration cycle or a resorption refrigeration cycle, its shortcoming is that the refrigeration process of the basic cycle is intermittent, and it is a high-temperature desorption heat input, and the primary refrigeration capacity (evaporative phase change latent heat refrigeration or desorption heat Refrigeration) output, that is, the input of high-temperature desorption heat and the output of cooling capacity are equal in terms of the number of cycles, but the amount of energy is different. Therefore, this way of heat input and cooling capacity output limits adsorption, Improvement of System Performance in Readsorption Refrigeration Cycle
[0004] After searching the public literature of the existing technology, it is found that the main measures to improve the performance of solid adsorption refrigeration are to adopt enhanced heat transfer and heat recovery technology, rather than improving the traditional solid adsorption refrigeration cycle as the main means, such as The Chinese patent application number is CN01111038.4 "Multi-effect adsorption refrigeration cycle system with independent heating / heat recovery / mass recovery / cooling" patent, which is to improve the working performance of solid adsorption refrigeration cycle by adopting heat recovery technology , and the heat recovery process is only part of the sensible heat recovery; the Chinese patent application number is CN200410025398.0 "Efficient and Reliable Adsorption Refrigerator Based on Separated Heat Pipes", which is to improve the performance of the refrigeration system by using heat pipes to enhance heat transfer technology. performance; did not involve the development of a new solid adsorption refrigeration cycle system

Abstract

The invention relates to a double-effect and double absorption typed refrigerating cycle system, belongs to the refrigerating air conditioner technology field. In the invention, a high temperature reactor is connected with a condenser by a high temperature control valve. The condenser is connected with the inlet of an evaporator by a throttle valve. The left outlet of the evaporator is connected with a left low temperature reactor by a left low temperature control valve. The outlet of the left lower temperature reactor is connected with the inlet of a high temperature reactor by a left re-absorption control valve. The right outlet of the evaporator is connected with the inlet of a right low temperature reactor by a right low temperature control valve. The outlet of the right low temperature reactor is connection with a medium temperature reactor by a right re-absorption control valve. The outlet of the medium temperature is rightly connected with the condenser by a medium temperature control valve. The insides of the high temperature reactor, medium temperature and low temperature reactor are separately installed with reactor heating and cooling coils and are filled with adsorbent. The heat exchange coils are separately installed inside the condenser and the evaporator. The double-effect and double absorption typed refrigerating cycle system not only significantly improves the operating property of solid absorption typed refrigerating cycle system, but also solves the problem of non-continuous refrigerating process.

Description

technical field [0001] The invention relates to a system in the technical field of refrigeration and air conditioning, in particular to a double-effect dual-adsorption refrigeration cycle system based on an adsorption-resorption process and an internal chemical reaction heat recovery process. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, the energy consumption of production and life in the whole society has increased sharply, especially as people's demand for environmental comfort continues to increase, and building energy consumption has almost accounted for the energy consumption of the entire society. Half of the total value, and the gradual popularization and application of refrigeration and air conditioning make the energy consumption of refrigeration and air conditioning account for the vast majority of building energy consumption. Therefore, it is of great significance to develop an...
