Ground Source Heat Pump for Greenhouse
The Zhongkeneng (ZKN) Planting Special Heat Pump Unit is a heat pump unit developed by the company based on many years of experience in heat pump production. Relying on advanced control systems and the reverse Carnot cycle principle, it uses the cycle to collect heat energy from groundwater or air, and then converts energy. The outlet temperature is 35℃~55℃ during heating. It is a device that uses geothermal energy or air energy and other low-level energy sources for heating. It is suitable for temperature control places such as greenhouse planting, greenhouses, cultivation, flower fields, agriculture, and ecological gardens.
