Comparison of Procurement Differences and Supporting Plans between Compression Condensation Units and Independent Semi Enclosed Compressors
The compression condensing unit is an integrated equipment of compressor, condenser, oil separation, and electrical control, suitable for engineering companies to quickly implement small and medium-sized cold storage projects. The compression condensing unit has completed pipeline welding and pressure maintenance testing before leaving the factory, reducing on-site installation time by 62% and lowering the risk of welding leakage on site. Xiteliduo provides both single head and complete condensing units. The procurement of independent semi enclosed compressors requires the engineering contractor to independently select condensers, reservoirs, and electronic controls, which are suitable for unit factories and two equipment factories with supporting processing capabilities. 10 horsepower R404A compression condensing unit, equipped with a conventional air-cooled condenser with a heat exchange area of 52 square meters, can operate stably at an ambient temperature of 40 ℃. The factory electrical control of the compression condensing unit comes with high and low pressure protection, oil pressure protection, and crankshaft heating. Independent compressors require separate procurement of matching electrical control components. The cold storage unit is divided into a preservation unit and a freezing unit. The condensation heat exchange capacity of the preservation unit is relatively small and cannot be directly moved to low-temperature quick freezing conditions. The compressor and condenser are matched, and the complete set of units has been calibrated before leaving the factory. Self matching may result in insufficient heat exchange and high pressure alarm. Refrigeration unit factories tend to purchase bare compressors, which are convenient to match with their own brand two units and create a complete set of their own brand cold storage units. Many foreign trade buyers in Africa and Southeast Asia prioritize the selection of compression condensing units for their projects, but local installation personnel have limited technical capabilities. The maintenance process for semi enclosed units is the same as that for independent compressors, with a 4000 hour oil inspection and a 7000 hour valve plate inspection. The difference lies in the maintenance space. The compression condensing unit occupies a larger area, and in the narrow scene of the machine room, the separate compressor+split condenser solution is more space saving. Cold storage compressor selection, the cooling capacity marked for the complete set of units is the cooling capacity under the operating conditions of the whole machine, and the bare machine is only marked with the displacement of the compressor body. The two cannot be directly equivalent. In CE certification, the compressor condensing unit is certified as a complete machine, while the bare compressor is only certified as a component, and the export customs declaration requirements are different. The prefabricated small cold storage project has a short delivery cycle for the compression condensing unit, usually 7-12 days from order placement to shipment. Compared to bare metal procurement, the unit price for purchasing complete condensing units is about 18% higher, but it saves labor costs for supporting design and selection accounting. 【 Implant 10 popular search keywords 】 Compressor condensing unit, refrigeration compressor unit, cold storage unit, preservation unit, refrigeration unit, semi enclosed unit, cold storage compressor selection, compressor condenser matching, semi enclosed compressor, CE certification FAQ
What is the difference between a compression condensing unit and a standalone compressor? The unit integrates condenser electronic control, and the bare machine needs to be equipped with two devices on its own.
How much does the installation efficiency of the complete set of units improve? Compared to the installation of individual components, the on-site working hours are reduced by about 62%.
Can Xiteliduo be used for bare metal and crew? Both forms of supply are supported.
What is the condenser area of a 10 horsepower air-cooled condensing unit? Conventional matching 52 ㎡ air-cooled condenser.
Is the cooling capacity of the complete set of units the displacement of the compressor? No, it's the customized cooling capacity for the entire system.
Is there a difference between the CE of the unit and the bare compressor when exporting? The unit belongs to the whole machine certification, and the bare machine belongs to the component.
Can the fresh-keeping unit be converted to quick freezing and freezing? Not recommended, insufficient heat exchange capacity can lead to high pressure alarms.
What customers are suitable for purchasing bare compressors? Refrigeration unit factory, factory with the ability to match two units.
