DC cabinet airconditioner cooling princple: the high-pressure refrigerant liquid in the system enters the evaporator and evaporates to absorb heat of the air in the cabinet, so the air is cooled, and the refrigerant that evaporates into gas in the evaporator is inhaled by the compressor and compressed into the high-pressure and high-temperature refrigerant gas, which enters the condenser and cooled to refrigerant liquid, and then re-enters the evaporator to cool the indoor air, and circulates accordingly

Proper cabinet cooling system selection is essential for maintaining a stable environment inside electrical enclosures. Overheating can cause equipment failure, reduced lifespan, and increased operational costs. Choosing the right cabinet air conditioner requires a detailed evaluation of several factors.
Maintaining an optimal temperature is critical for sensitive electronic components. The panel AC unit should effectively regulate heat within the specified range.
The total heat dissipation inside the enclosure determines the required cooling capacity. A mismatched cabinet cooling unit may lead to inefficient temperature control.
Outdoor cabinet air conditioners should be rated for peak ambient conditions to prevent performance degradation in extreme temperatures.
For installations in noise-sensitive areas, selecting a low-noise panel AC ensures minimal disturbance.
Selecting a cabinet cooling system with sufficient cooling capacity allows for future equipment upgrades without compromising thermal management.
By considering these factors, you can choose an efficient cabinet air conditioner that meets your equipment's cooling demands.
Ensuring compliance with regulatory standards enhances safety and reliability. Key industry norms include:
GB 4208 – Enclosure Protection Class
GB 4706.1 – Safety of Household and Similar Electrical Appliances
GB 9237-2001 – Mechanical Refrigerating Systems Used for Cooling and Heating - Safety Requirements
GB/T 17626.8 – Electromagnetic Compatibility - Power Frequency Magnetic Field Immunity Test
| Fault State | Possible Causes | Solutions |
|---|---|---|
| The cabinet temperature is too high, but the air conditioner is not working. | 1) Power failure. 2) Cooling set temperature is too high. 3) System fault. | 1) Check power supply and circuit. 2) Adjust cooling temperature. 3) Contact professional maintenance. |
| The air conditioner is running, but cooling is ineffective. | 1) Cooling capacity mismatch. 2) High ambient temperature. 3) System fault. | 1) Upgrade or add another cabinet cooling unit. 2) Ensure operation within specified conditions. 3) Contact professional maintenance. |
| The air conditioner stops suddenly, but the electrical system is normal. | 1) Cabinet temperature has reached the set point. 2) Other system faults. | 1) Adjust temperature settings. 2) Contact professional maintenance. |
The standard warranty period is 12 months from operation start or a maximum of 18 months from delivery, depending on the agreement.
During the warranty period, faults caused by panel AC unit quality issues will be repaired for free. However, the following cases are not covered:
