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.

Abstract

This invention relates to the field of heat pump technology and provides an adsorption heat pump system, including a first adsorption bed, a second adsorption bed, a condenser, an evaporator, and an intelligent controller. The first and second adsorption beds are connected in parallel between the condenser and the evaporator. Temperature sensors and flow sensors are installed on both the first and second adsorption beds. A first valve group is installed on the pipeline between the first and second adsorption beds and the condenser and evaporator. The intelligent controller is electrically connected to each sensor and the first valve group. The intelligent controller determines the desorption or adsorption completion status of the two adsorption beds based on the detection results of each sensor, ensuring that one bed is always in a desorption state and the other in an adsorption state, providing a continuous and stable heat source for subsequent steam preparation or heating. Simultaneously, by deeply coupling the adsorption heat pump system with a steam booster system, continuous high-temperature steam preparation is achieved, improving the system's steam supply temperature and pressure levels.
