Abstract
The invention discloses a solar-driven jetting-dual-adsorption-bed combined refrigeration system, and relates to the technical field of refrigeration. The problem that a refrigeration system is low in refrigeration efficiency due to the fact that traditional jetting refrigeration and adsorption refrigeration cannot be carried out synchronously is solved. The solar-driven jetting-dual-adsorption-bed combined refrigeration system is composed of a jetting refrigeration system, a dual-adsorption-bed adsorption refrigeration system, a dual-adsorption-bed cooling system and a condenser cooling system. After hot steam is used for driving the jetting refrigeration system, the high-temperature hot steam flowing out of a jet drives the dual-adsorption-bed adsorption refrigeration system again to conduct continuous intermittent refrigeration, it is ensured that water steam heated by solar energy can be repeatedly utilized, jetting refrigeration and adsorption refrigeration are carried out synchronously, and the refrigeration efficiency of the combined system is improved.
