At Tongyi Heat Pump, the energy reduction required for defrosting provides a 10% increase in heat capacity compared to other traditional defrosting systems.

Our commitment to perfection has driven us to introduce intelligent defrost processes that transform the management of defrosting cycles in air-to-water heat pumps, increasing Coefficient of Performance (COP) values.

Through skillful integration of advanced technology, not only the defrosting process has been optimized, but also attained a remarkable milestone in energy reduction. This ingenious approach not only ensures effective defrosting but also elevates heat capacity by 10%, a significant advancement when compared to units equipped with conventional defrosting systems.

This breakthrough translates into tangible benefits for you. Witness an impressive increase in the Coefficient of Performance (COP) values with Tongyi Heat Pump units, delivering enhanced efficiency and performance. At Tongyi Heat Pump, we’re driven by innovation that truly matters – enhancing your experience, saving energy, and maximizing the potential of your heat pump uses. 

Join us in embracing a new era of heat pump technology, where intelligent design meets exceptional performance.
