Free cooling air-cooled chiller

Cooling Capacity (kW): 26.4~700
EER: 2.7~3.0
1. The units have compact structure and small size, with simple design for water pipe system, with convenient installation and maintenance at site. Only the external water pipes and main power supply are required to be connected at site, then it can be easily tested and operated. Easy to install and debug.

2. Through intelligent microcomputer control technology, according to the load varies, the units automatically adjust the devoted compressor output, it maintains the best match in the highest efficient at any time.

3. The units provide highly accurate water temperature control, to ensure the constant and comfortable temperature environment for indoor air-conditioned spaces, greatly improve the comfort of the indoor environment.

4. The units are installed with well-known brands new generation high-efficiency & high IPLV double screw compressors, 5:6 high-efficiency patent asymmetric teeth. Compressors are equipped with capacity controller to achieve muti-step or step-less energy adjustment.

5. Microcomputer control system, with strong security, communication, fault diagnosis and automatic adaptation function.

6. The main parts of refrigeration system are from famous brands at home and abroad, superior performance and reliable operation.

7. Set the high and low pressure protection, chilled water anti-freeze protection, power phase sequence protection, default phase protection, lack of water flow protection, compressor motor overload/overheating protection and auto-restart function on power failure, set password on control interface to prevent faulty operation.

8. Unique free-cooling coil and condenser integrated design, heat transfer efficiency is 20% higher than conventional split type. AEER can be up to 10~20.

9. Free cooling air-cooled chiller, according to the changes of machine room and environmental conditions, has designed three flexible control modes (compressor refrigeration, mixed refrigeration, complete free-cooling), and coordinate the implementation of the various components of the action, under the premise of safe and reliable, to maximize the use of natural cold source.
