Condensing Unit Selection Guide

Core Selection Factors

1. Cooling Capacity Requirements: Calculate based on the volume, temperature requirements and heat load of the cooled object. Kaidi provides professional pre-design calculation services to accurately match unit models.
2. Operating Environment: Prioritize evaporative or water-cooled units in high-temperature environments; recommend air-cooled products in water-scarce areas. All Kaidi series have environmental adaptability.
3. Operating Conditions: Recommend screw or parallel units for low-temperature scenarios (≤-20℃); scroll or piston units are optional for normal-temperature scenarios (0-10℃).
4. Energy Efficiency Requirements: Choose first-level energy efficiency units for energy conservation. Kaidi screw units and parallel units all meet the national first-level energy efficiency standards.
5. Installation Conditions: Choose Mini or V-type units for space-constrained areas; prioritize barrel pump units for long-distance liquid supply. Kaidi provides on-site survey and installation scheme design.

Installation and Maintenance Key Points

Installation Specifications

1. Reserve a heat dissipation space of ≥30cm for unit installation; avoid direct sunlight and closed environments for air-cooled units.
2. Adopt flange or welding connection for pipeline connection; pressure test must reach 1.6MPa and maintain pressure for 24 hours without leakage.
3. Electrical connection must comply with local voltage standards, with grounding resistance ≤4Ω. Kaidi provides professional installation guidance and commissioning services.

Daily Maintenance Process

1. Daily: Check operating pressure, temperature and noise, and record unit operating parameters.
2. Weekly: Clean dust on condenser fins, check refrigerant level and oil level.
3. Monthly: Tighten electrical wiring, test the effectiveness of protection devices.
4. Annual: Conduct comprehensive disassembly and cleaning, replace filters and lubricating oil. Kaidi provides annual maintenance service packages.

Common Fault Troubleshooting

Frequently Asked Questions (FAQ)

1. How to choose the cooling method of the condensing unit?

   For sufficient water sources and pursuit of high heat exchange efficiency, water-cooled type is preferred; for water-scarce areas or limited installation space, air-cooled type is optional; for dry areas and need to balance energy conservation, evaporative type is recommended. Kaidi can provide customized solutions according to on-site conditions.
2. What are the advantages of parallel condensing units?

   Parallel units have the advantages of modular expansion, energy saving under partial load, and redundancy guarantee. A single unit failure will not affect the overall operation. Kaidi parallel units support the combination of 2-16 modules, with energy efficiency increased by more than 20% under partial load.
3. How to achieve energy-saving operation of condensing units?

   Choose first-level energy efficiency products, equip with intelligent control systems, and regularly maintain heat exchange components. Kaidi units are equipped with permanent magnet synchronous motors and frequency conversion technology, with energy efficiency increased by 35% when the load rate is 30%, saving 15%-25% of annual electricity costs.
