Problems solved by technology

However, ordinary adsorption heat pumps only rely on the pressure difference between the adsorption bed and the evaporator / condenser to push the refrigerant to move in the whole system, and the effective adsorption amount of the adsorbent is small during the working process, resulting in low output cooling power of the equipment and low cooling performance. Coefficient (COP) and other problems seriously affect the performance of adsorption heat pumps

Description

technical field [0001] The invention relates to a novel adsorption heat pump with a vacuum booster pump and an adsorption-desorption method using the adsorption heat pump, belonging to the technical field of adsorption refrigeration. Background technique [0002] At present, the utilization rate of industrial waste heat in my country is relatively low, especially for low-grade industrial waste heat. Due to the low heat energy density and low recovery efficiency, it is basically discharged directly, and energy waste is serious. As a clean and cheap renewable energy, how to realize efficient utilization, It is of great significance in alleviating energy shortage. Adsorption heat pumps can use low-grade thermal energy such as industrial waste heat above 60°C and solar energy to generate cold energy, and replace ordinary electric compression air conditioners with heat for refrigeration, saving the power consumption of air-conditioning and cooling. An important measure for effici...
