U Type Condensing Unit Manufacturers

U-Type Condensing Unit is a compressed condensing device featuring an integrated cabinet-style structural design, a name derived from its unique U-shaped piping layout and compact integrated form. This type of unit consolidates core components like the compressor, condenser, and liquid receiver within a structurally compact cabinet. It achieves an efficient refrigeration cycle by optimizing airflow design and heat exchange efficiency.

Product Core: Structure and Function

Structurally, the U-Type Condensing Unit employs an integrated cabinet-style design. This not only ensures a neat and aesthetically pleasing appearance but, more importantly, enables a scientific layout of internal components.

A typical structure includes the outer casing, symmetrically positioned left and right external fans, internal compartments separating the compressor and liquid receiver areas, and meticulously arranged condenser piping.

The core advantage of this design lies in its airflow uniformity. Through carefully calculated airflow channel design, the U-Type Condensing Unit can fully utilize the heat exchange capacity of the condenser, improving the overall Coefficient of Performance (COP).

It is worth noting that Zhejiang Kaidi Refrigeration incorporates multiple practical considerations into its U-Type Condensing Unit design: access doors are equipped with safety locks for easy yet secure maintenance; cabinet side walls feature soundproofing and insulation layers, significantly reducing operational noise.

Operational Principle: Pressure Balance and Heat Exchange

The operation of a U-Type Condensing Unit is based on the principles of the refrigeration cycle and pressure balance. In a refrigeration system, a pressure difference exists between the high-pressure side (generator and condenser) and the low-pressure side (evaporator and absorber), which needs to be maintained by appropriate mechanisms.

The U-shaped tube structure plays a key role here. It not only serves as a passage for refrigerant flow but, more importantly, can form a liquid seal. This prevents gas from the high-pressure side from directly entering the low-pressure side while helping to maintain the required system pressure differential.

Regarding heat exchange efficiency, the U-Type Condensing Unit ensures the refrigerant fully releases heat within the U-shaped piping, completing the phase change from gas to liquid, through optimized piping layout and airflow design.

This process is further enhanced in Kaidi's units, which utilize external rotor motors and specially designed fan systems. This ensures efficient heat exchange while significantly reducing operational noise.

Technical Comparison: Compressor Selection Guide

The choice of compressor type directly impacts the performance of a U-Type Condensing Unit. Currently, the two mainstream technologies on the market are scroll compressors and screw compressors, each with its own characteristics suited for different application scenarios.

To help you visually understand the differences between these two compressors, we have compiled the following comparison table:
