IntroductionOur low-temperature screw-type air-cooled heat pump units are specially designed for heating in northern regions. They are widely used in residential communities and large commercial buildings with heating areas of 2,000 to 10,000 square meters, particularly suitable for replacing radiators in urban renewal projects. With high energy efficiency ratio at low ambient temperatures, they can produce 60-degree hot water at -35°C and 70-degree hot water at -25°C, making them a boiler alternative solution.

Application Areas: Hotels, activity centers, factories, staff dormitories, and other locations requiring heating/air conditioning.

Cooling Range: 70KW ~ 1800KW; Heating Range: 80KW ~ 1880KW

Chilled Water Temperature Range: 5℃ ~ 20℃ Hot Water Outlet Temperature: 50℃

　　Engineered features:

(1) Heat pump systems can both cool and heat, serving multiple purposes: One system can replace the original two systems of a boiler and air conditioner; in doing so, it saves a significant amount of energy while also reducing the initial investment in equipment.

(2) The compressor is a screw-type single machine double-stage compressor, featuring true two-stage compression and strong inter-stage gas injection to increase enthalpy, suitable for extremely cold regions. Equipped with low-temperature strong heat technology, the heating capacity remains stable between -35 to 30°C, without diminishing as the ambient temperature drops.

(3) Break with tradition with the innovative four-way valve assembly design, allowing the unit to continue uninterrupted operation during defrosting, significantly enhancing actual operating efficiency. The overall energy efficiency for the heating season is 2.8.

(4) Equipped with self-developed and produced high-efficiency finned condensers, evaporators, providing ample refrigeration capacity, high efficiency, and easy cleaning and maintenance.

(5) Fully automatic computer control, no need for human monitoring, allowing for remote or centralized management.
