AI Technical Summary

Technical Problem

When the use of ice water and hot water is not completely synchronized, the existing heat pump system is prone to paralysis due to excessive hot water temperature or low ambient temperature, and the system cannot be continuously produced by hot and cold water.

Method used

A heat pump system including a heat transfer system and an environmental heat exchange system is designed. The heat transfer system transfers heat through hot water tanks, cold water tanks and heat pump pipelines. The environmental heat exchange system exchanges heat with the external environment through the environmental heat exchanger and environmental heat exchange pipelines to ensure that the system continues to operate under different environmental conditions.

Benefits of technology

It realizes continuous production of hot and cold water under different environmental conditions, reduces dependence on ambient temperature, and avoids paralysis caused by excessive temperature or too low system.
