When selecting a compressor, you shall first clarify your application scenario (industrial air supply / refrigeration), and confirm the required discharge pressure, actual air consumption / refrigeration load, daily continuous operation duration, as well as medium requirements such as gas cleanliness and explosion protection. Reciprocating compressors are suitable for intermittent air supply with low flow rates, scroll compressors for medium-and-small-flow applications requiring quiet operation and clean air, variable-frequency screw compressors are the top choice for stable 24-hour air supply, and centrifugal compressors are adopted for centralized air supply with ultra-large flow rates. For refrigeration scenarios, match appropriate scroll, reciprocating or screw refrigeration compressors based on warehouse temperature, cooling load and refrigerant. Meanwhile, reserve a margin of 10%-20%, and finalize the model comprehensively by taking budget and post-operation maintenance costs into consideration.

The specifications of evaporators are mainly classified by heat exchange area, applicable refrigeration capacity, fin spacing, pipe diameter, air volume and wind pressure of fans, coil rows, pipeline materials, installation forms (ceiling-mounted / floor-standing / side air outlet), applicable refrigerants and operating temperature ranges. They are also categorized by structural types such as cold storage air coolers, shell-and-tube evaporators, plate evaporators and double-pipe evaporators. Anti-frost specifications with wide fin spacing are adopted for low-temperature cold storage, while compact fin specifications with high heat exchange efficiency are selected for high-temperature fresh-keeping storage. Shell-and-tube evaporators are matched with water-cooled units, and double-pipe or plate evaporators are mostly used for small refrigeration equipment. Model selection needs to match the refrigeration capacity of compressors, cold storage temperature load and spatial dimensions.

Sea freight is generally adopted for large-volume shipments, while air freight is used for small batches. For customized products, shipment arrangements can only be made after completing sample confirmation, production acceptance and reinforced packaging procedures. For sea freight, container load capacity shall be calculated in advance, and buffer time for customs declaration and shipping schedules shall be reserved. It is suitable for bulk orders with loose lead times and cost sensitivity. Air freight delivers fast transit times, which can cater to urgent small-batch orders and supplementary sample shipments yet comes with higher logistics costs. Prior to delivery, the dimensions, specifications and protective packaging of customized accessories must be verified, and customs declaration documents shall be prepared simultaneously. For cross-border exports, supporting documents such as commodity inspection certificates and certificates of origin shall be provided in accordance with the requirements of destination countries. Small scattered customized parts can also be shipped directly via express delivery channels to achieve flexible trade-offs between transit time and transportation costs.
