Multi-effect adsorption type cooling cycle system

Abstract

A multi-effect adsorption-type refrigeration cycle system belongs to the refrigeration air-conditioning technology field. In the multi-effect adsorption-type refrigeration cycle system, a high-temperature reactor is connected with a high-temperature reactor desorption valve; a medium-temperature reactor is connected with a medium-temperature reactor desorption valve; a low-temperature reactor is connected with a low-temperature reactor desorption valve; the outlets of the high-temperature reactor desorption valve, the medium-temperature reactor desorption valve and the low-temperature reactor desorption valve are all connected with the inlet of a condenser which is connected with a throttle valve; and the outlet of the condenser is respectively connected with the inlets of the high-temperature reactor desorption valve, the medium-temperature reactor desorption valve and the low-temperature reactor desorption valve. The high-temperature reactor desorption valve, the medium-temperature reactor desorption valve and the low-temperature reactor desorption valve are respectively equipped with a reactor heating and cooling coil, and are filled with an adsorbent. During each cyclic process, three times of refrigerating output can be realized by inputting the thermal desorption once, thereby remarkably improving the refrigerating efficiency of the adsorption refrigeration technology and at the same time reducing the system requirement for the heat of the external heat source.

Description

technical field [0001] The invention relates to a system in the technical field of refrigeration and air conditioning, in particular to a multi-effect adsorption refrigeration cycle system based on an internal heat recovery process. Background technique [0002] Solid adsorption refrigeration is a green refrigeration technology driven by heat energy. Compared with the traditional vapor compression refrigeration driven by electricity, it is characterized by the effective use of solar energy and low-grade waste heat as the driving force to achieve refrigeration effects. , At the same time, due to the use of environmentally friendly refrigerants as the working medium, it has the environmental protection advantages of zero ozone depletion coefficient (ODP) and greenhouse effect coefficient (GWP), which is suitable for the current environmental protection requirements. Especially in recent years, with the continuous increase of people's demand for comfortable air-conditioning, th...
