Features & Benefits

Features and Core Advantages of Air-Cooled Air Conditioning Systems

Cooling Medium

Uses air as the heat exchange medium, removing battery heat through forced convection.

Simple Structure

The system mainly consists of a compressor, condenser, evaporator, expansion valve, and fans, requiring no complex liquid piping.

Easy Installation and Maintenance

Modular design allows for flexible installation. Maintenance is relatively simple, with filters that can be regularly replaced or cleaned.

Suitable for Small to Medium Systems

Ideal for single cabinets or small containerized energy storage systems (typically with heat loads ≤ 30kW).

Large Temperature Difference

The temperature difference between the air outlet and return air inlet is typically 8–12°C, resulting in poorer temperature uniformity across batteries.

Lower Cost

Initial investment and ongoing maintenance costs are lower than those of liquid-cooled systems.

Fast Deployment

No need for complex procedures such as liquid circuit draining or leak prevention, resulting in a short on-site installation cycle.

High Reliability

No risk of liquid leakage, freezing, or liquid line blockages

Simple Maintenance

Operation and maintenance personnel do not require specialized liquid-cooling skills; simply replace fans or filters as needed.

Wide Adaptability

Capable of normal operation in a broad temperature range from -30°C to +55°C.

Features and Core Advantages of Liquid-Cooled Air Conditioning Systems

Cooling Medium

Uses coolant (ethylene glycol aqueous solution or dielectric coolant) as the heat exchange medium, directly带走 the heat from battery cells via cold plates or cooling plates.

Complex Structure

The system includes a chiller unit, circulation pump, expansion tank, plate heat exchanger, liquid cooling piping, and cold plates.

High Installation and Maintenance Requirements

Requires professional personnel for liquid circuit design, air purging, and leak prevention. Maintenance costs are relatively high.

Suitable for Large/High-Power Systems

Ideal for large-scale energy storage power stations and high-power-density containers (heat load ≥ 50kW, and can reach 200kW+).

Small Temperature Difference

The temperature difference across the cold plate surface can be controlled to ≤3°C, providing excellent temperature uniformity among battery cells.

High Heat Dissipation Efficiency

The thermal conductivity and specific heat capacity of coolant are far superior to those of air, delivering several times greater heat dissipation capacity per unit volume.

Extended Battery Life

Precise temperature control (±1°C) significantly slows battery cell aging and extends the overall system lifespan.

High Space Utilization

Liquid cooling piping occupies a small footprint, facilitating high energy density layouts within limited spaces.

Low Operating Noise

No high-power fans; the main noise comes from the compressor and water pump. It is 5–10 dB(A) quieter than air-cooled systems.

Adaptability to Extreme Operating Conditions

Capable of meeting instantaneous heat dissipation demands in high-rate charge/discharge scenarios of 2C to 4C.
