Free Cooling Air Cooled Scroll Chiller

Free Cooling Air Cooled Scroll Chiller is an energy-efficient refrigeration equipment. This series of products integrates free cooling function and provides three intelligent operation modes: mechanical cooling, mixed cooling and free cooling. It can automatically switch the operation mode according to the ambient temperature and load demand, make full use of the outdoor free air cooling source in the transition season or low temperature season, reduce the operation time of the compressor mechanical cooling, and greatly reduce energy consumption. The unit's annual operation energy efficiency ratio EER can reach more than 12.0. It is suitable for places that require year-round cooling, such as industrial manufacturing,data centers, communication base stations and large commercial buildings.

1. With R410A environmentally friendly refrigerant and good cooling effect.

2. Adopt natural cooling heat exchanger, in free cooling mode, use the outside cold air to reduce the cooling water temperature.

3. Equipped with an intelligent control system , can monitor ambient temperature, unit operating status, load demand in real time, and automatically switch operating modes to maximize efficiency throughout the year.

4. With the combination of famous brand compressors, high efficient shell and tube condensers/finned condensers and shell and tube evaporators, excellent cooling, quiet with low electric consumption.

5. Microcomputer LCD chiller controller, simultaneously displays the cold water outlet and the set temperature, easy to operate with accuracy of controlling water temperature within 3℃ to 50℃.

6. Current overload protection, high and low pressure protection system and electronic time delay, and an abnormal visual display system.

7. Optional for double compressor, three compressor, four compressor combinations, independent system, high energy efficiency.

8. Optional  communication function to realize automatic remote management.

The free cooling air-cooled chiller combines three modes: standard cooling, mixed cooling, and natural cooling. It automatically switches between these modes based on ambient temperature and load demand.

Standard Cooling Mode:

When the ambient temperature is high or the load is large, the unit performs mechanical cooling through the compressor and refrigerant system. The refrigerant absorbs heat in the evaporator, and the heat is dissipated into the outside air through the air-cooled condenser. The cooled water flows through the evaporator and then to the load equipment, carrying away the heat.

Mixed Cooling Mode:

When the ambient temperature is between the set temperature and the natural cooling temperature (5-10°C lower than the set temperature), the unit performs mechanical cooling through the compressor and refrigerant system. At the same time, the bypass valve opens, and the natural cooling system starts. Both cooling systems operate simultaneously for cooling.

Natural Cooling Mode:

When the ambient temperature is below a certain threshold (more than 10°C lower than the set temperature), the unit shuts down the compressor, the bypass valve opens, and it directly uses the outside low-temperature air for heat exchange cooling to achieve the cooling effect.

Microcomputer LCD chiller controller simultaneously displays the chilled water outlet and the set temperature, making it easy to operate and accurately control the water temperature within 3°C to 50°C;

Equipped with an intelligent control system, can monitor ambient temperature, unit operating status, load demand in real time, and automatically switch operating modes to maximize efficiency throughout the year;
