AI Technical Summary

Technical Problem

In existing adsorption heat pump systems, the switching timing of the dual adsorption beds deviates significantly from the actual completed state, resulting in the inability to precisely synchronize the adsorption and desorption stages, interruption of refrigerant circulation, and intermittent heat output from the condenser, which fails to meet the continuous and stable heating needs of industry.

Method used

An intelligent controller, combined with temperature and flow sensors, monitors the adsorption bed status in real time. The system determines whether desorption or adsorption is complete by measuring the rate of temperature change and flow rate changes. It also controls the valve group to alternately connect the adsorption bed with the condenser and evaporator, ensuring continuous refrigerant flow within the system and enabling synchronous switching between the two bed states.

Benefits of technology

It achieves continuous and stable heating of the adsorption heat pump system, improves adsorbent utilization and system thermal efficiency, reduces ineffective energy consumption, and enhances the system's industrial applicability and operational reliability.
