Working Principle
The operation of Other Condensing Units is based on the condensation link of the vapor compression refrigeration cycle, with the specific process as follows:
- After the high-temperature and high-pressure gaseous refrigerant is discharged from the compressor, it enters the condensation chamber of Other Condensing Units;
- Through air-cooled or water-cooled methods, the refrigerant exchanges heat with the cooling medium (air or water) to release heat;
- After the heat is taken away by the cooling medium, the refrigerant condenses into normal-temperature and high-pressure liquid, which is transported to the evaporator through the throttling device to complete the closed loop of the refrigeration cycle.
In equipment design, Kaidi has optimized the structure of the condensation chamber and the heat exchange path, increasing the heat exchange efficiency by more than 15% while reducing the operating noise.

Frequently Asked Questions (FAQ)
Q1: How to choose between air-cooled and water-cooled Other Condensing Units?
A1: Air-cooled types do not require additional water sources, feature flexible installation, and are suitable for scenarios with inconvenient water sources or small-to-medium refrigeration demands (e.g., convenience stores, small warehouses). Water-cooled types have higher heat exchange efficiency, and are suitable for scenarios with large refrigeration capacity and long-term continuous operation (e.g., large cold chain logistics parks, industrial workshops). Based on users’ site conditions, refrigeration requirements and budget, Kaidi can provide professional selection schemes.
Q2: What should I do if high-pressure alarm occurs during the operation of Other Condensing Units?
A2: High-pressure alarms are mostly caused by dirt on the condenser surface, insufficient flow of cooling medium or excessive refrigerant charge. First, inspect and clean the condenser; then, check the operation status of the cooling fan (for air-cooled type) or cooling water pump (for water-cooled type); if the problem is not resolved, you can contact Kaidi’s after-sales team, and professional technicians will test and adjust the refrigerant charge.
Q3: How to ensure the energy-saving effect of Other Condensing Units?
A3: Kaidi’s Other Condensing Units adopt optimized heat exchange structure design and high-efficiency compressors, and have passed strict energy efficiency tests before leaving the factory; they are also equipped with an intelligent variable frequency control system, which can dynamically adjust the operating power according to the refrigeration load. In addition, Kaidi’s professional pre-sales team will customize the optimal refrigeration scheme according to user scenarios, ensuring energy-saving effects throughout the entire process from equipment selection, installation layout to system commissioning.
