Features

• Application environment: hotels, schools, hospitals, factories, residential quarters and other places requiring heating and cooling.
• Stable, reliable, economical and energy-saving: the special compressor of Copeland ZW series heat pump (enhanced vapor injection) is adopted, which has stable operation, high energy efficiency ratio and more excellent effect in low temperature environment.
• Wide range of application temperature: high-precision electronic expansion valve and bypass throttling components can improve the energy efficiency and stability of the unit when operating at low temperature (heating in winter) and high temperature (cooling and heating in summer).
• Efficient heat exchange: air-side heat exchanger with internally threaded cop tube is adopted to effectively disturb the flow of the refrigerant and improve the heat exchange performance.
• Good anti-freezing performance: the water-side heat exchanger with good anti-freezing performance and multiple anti-freezing protection functions are adopted.

How it Works?

A small amount of electric energy is used to drive the air source heat pump unit to operate, and transfer the energy in the air through the heat exchanger to the water. In winter, more than 41℃ hot water is generated. Through the action of the pump, the hot water flows in the indoor floor heating pipe, fan coil unit and radiator, so as to achieve the purpose of heating. In summer, the cold water of 7℃ is generated. Through the action of the pump, the cold water flows in the fan coil and reduces the indoor temperature. The energy saving effect of the air source heat pump is obvious, without any emissions, which is an environmental protection product.
