Air-cooled Chiller
Product information
There is no need for auxiliary equipment such as cooling towers,especially for poor water quality or areas where water is scarce.Just connect the inlet and outlet water pipes and power supply and put them into use. Configuration features:The use of imported brand-name fully enclosed reciprocating/scroll compressor.The condenser is equipped with highly efficient sizing fins and internally threaded copper tubes,which has high heat exchange efficiency,good stability,and easy cleaning and maintenance.The evaporator adopts internal and external screw-type reinforcing tubes.The inner surface of the copper tube has threads,and the outer surface of the copper tube is smooth,and the cooling effect is good.Protection system devices:The unit is equipped with phase loss protection,reverse phase protection,over-voltage(under-voltage)protection,over-current protection. compressor motor overheat protection,start-up delay protection,chilled water temperature too low protection. and cooling temperature too low.Protection,cooling temperature protection is too high.
1、 Definition and working principle
Air-cooled chiller is a kind of refrigeration equipment that cools the condenser through the air, uses the compressor to circulate refrigerant (such as R134a, R410a), absorbs heat and dissipates heat into the air through the fan, thus providing constant temperature cooling water for industrial equipment, buildings or laboratories. Its core advantage is that it does not need cooling towers and water recycling systems, and is easy to install, which is suitable for water-limited or mobile needs.
2、Core components

Condenser:
Air cooled fin design, forced heat dissipation through the fan.
Evaporator :
Shell and tube type or plate heat exchanger, to achieve the heat exchange of water and refrigerant.
Control system:
Microcomputer control panel, support temperature setting, fault alarm, energy consumption monitoring.

5、 Selection suggestions
Cooling capacity calculation:
According to the equipment heat (Q= power x efficiency) and the ambient temperature, select the model with a redundancy of 20%-30% cooling capacity.
Environmental adaptability:
In high temperature areas (> 35 ° C), use a high-power fan or reduced capacity.
In a dusty environment, install an air filter and clean the condenser regularly.
Function extension:
Explosion-proof: chemical industry, oil and gas industry.
Frequency conversion: Continuous operation scenario with high energy saving requirements.
6、 Maintenance and maintenance
Daily maintenance:
Clean the condenser fins monthly (compressed air or soft brush).
Check the refrigerant pressure, replenish or detect leakage in time.
Quarterly maintenance:
Replace the water filter and clean the evaporator water side.
Calibrate temperature sensors and pressure switches.
Annual maintenance:
Check the lubricating oil status of the compressor and replace the aging parts (such as the filter dryer).
7、 Advantages and limitations
Advantages and limitations
No cooling tower is required, saving installation space. Cooling efficiency decreases in high temperature environments
Low maintenance cost (no water treatment) High noise (soundproofing required)
Adapted to mobile and outdoor scenes, the initial investment is slightly higher than water-cooled
8、 Comparison with water-cooled chiller
Comparison item | Water-cooled Chiller | Air-cooled Chiller |
Heat-dissipating method | Cooling by cooling water circulation (cooling tower) | Cooling by blower (no cooling tower required) |
High energy efficiency ratio (COP) | high（4.0-6.0） | low（2.8-4.5） |
Installation cost | High (cooling tower and water pipe system required) | Low (simple structure) |
Applicable scene | High load, continuous operation (e.g. factory, data center) | Small/medium load, mobile or outdoor scenes |
Maintenance requirement | Clean the condenser and water pipe regularly | Clean the fan and fins |
9、 Summary
With its convenient installation and easy maintenance, air-cooled chiller has become the first choice for small and medium-sized refrigeration scenarios.
