AI Technical Summary

Technical Problem

The existing air-cooled and heat pump module unit fluctuates greatly when the seasons and ambient temperature changes, and the overall unit cannot operate normally when the main unit fails, and cannot effectively monitor the matching degree of the module's heating capacity and heat demand, resulting in the impact of system stability.

Method used

By monitoring the heat demand of the load unit and the heating capacity of the module unit in real time, the number of module units invested is dynamically adjusted, and multiple module units operate independently to diversify risks and switch to the backup module unit combination mode in case of failure.

Benefits of technology

It realizes flexible combination and real-time matching of module units, avoids the risk of overall unit downtime, improves system stability and energy efficiency, and reduces the adverse effects caused by frequent start/stop of excess modules.
