Smart defrost helps reduce frost buildup on the outdoor heat exchanger and maintain heating performance in cold, humid conditions.

Optimized Air to Water Heat Pump Winter Performance

At Tongyi, our commitment to perfection has led to the development of intelligent defrosting processes that enhance air to water heat pump winter performance. By optimizing defrosting cycles, we have significantly increased the Coefficient of Performance (COP) values, improving overall efficiency.

Through the integration of advanced technology, we’ve not only optimized the defrosting process but also achieved a remarkable reduction in energy consumption. This innovation boosts heat capacity by 10%, setting a new standard compared to traditional defrosting systems and ensuring reliable performance even in the coldest winter conditions.

Enhanced Air to Water Heat Pump Winter Performance

This breakthrough delivers real, tangible benefits for you. Experience a significant boost in Coefficient of Performance (COP) values with Tongyi Heat Pump units, providing enhanced efficiency and performance throughout the winter months.

At Tongyi Heat Pump, innovation drives us to deliver what truly matters—saving energy, maximizing the potential of your heat pump uses, and improving your overall experience.

Join us in embracing a new era of heat pump technology, where intelligent design meets exceptional performance, ensuring reliable and sustainable heating all year long.
