Air-cooled water chiller/heat pump units are the central air conditioning units with air as the cold (hot) source, and water as the heat transfer medium. The units need no additional equipment room, cooling tower, cooling pump, or cooling pipe and can be mounted on the building roof and outdoors. The heat pump units can provide heat as a hot water boiler. This series of units are applicable to various environments, such as hospitals, hotels, factories, and office buildings.

Key Features & Technology

It’s the unique features of Daikin products that makes us the world leader.

Microprocessor controlled VSD provides smooth capacity modulation from 10% to 100%, it can achieve optimal energy efficiency at part load, contributing to better energy saving.

The star wheels made of high-strength composite material can ensure the accuracy and the minimum gap and guarantee operation without wear and tear. The oil injection and liquid injection design of the compressor minimizes air superheat and eliminates the possibility of oil and refrigerant decomposition due to superheat.

The removable side cover of the gate rotor box simplifies the routine inspection without the need of removing and installing pipelines. Such a design facilitates the check of the internal components of the compressor.

The gate rotor of DAIKIN single-screw compressor is made of special materials that can avoid metal engagement between the gate rotor and rotor. The small engagement gap and low engagement resistance implement “zero gap” engagement. The unique oil supply system that uses the oil pressure difference function enables more efficient sealing, lubrication, and cooling of the compressor. In this way, the engagement resistance is further reduced and the efficiency of entire units is improved.
