The following core products are the basic components of the refrigeration system, and their performance directly affects the refrigeration effect and energy consumption level of the whole system.
| Product Name |
Core Definition |
| Condensing Units |
An integrated device that compresses refrigerant vapor into high-pressure vapor and releases heat through condensation, composed of compressor, condenser, fan, etc. |
| Coolers |
A heat exchange device that transfers the heat of the medium to be cooled to the refrigerant, reducing the temperature of the medium |
| Evaporative Condensers |
A high-efficiency heat exchange equipment that combines the advantages of water cooling and air cooling, using water evaporation to take away heat |
| Evaporators and Condensers |
Evaporator: absorbs heat through refrigerant evaporation to realize cooling; Condenser: releases heat through refrigerant condensation. They are core heat exchange components of the refrigeration cycle |
| Pressure Vessels |
Special equipment that bears a certain pressure, used for storing refrigerants or other media in the refrigeration system, and must comply with strict safety standards |
2. Core Technology: Key Performance Indicators & Technical Advantages

2.2 Core Technical Principles (Simplified Schematic)
Refrigeration Cycle Principle of Evaporators and Condensers
- Evaporation Stage: Liquid refrigerant enters the Evaporator, absorbs heat from the cooled medium and vaporizes, turning into low-pressure vapor.
- Compression Stage: The compressor in the Condensing Unit compresses the low-pressure vapor into high-pressure high-temperature vapor.
- Condensation Stage: High-pressure high-temperature vapor enters the Condenser (or Evaporative Condenser), releases heat to the outside air or water, and condenses into high-pressure liquid.
- Throttling Stage: High-pressure liquid passes through the throttling device, pressure drops and turns into low-pressure liquid, then re-enters the evaporator to start a new cycle.
Kaidi Advantage: The Evaporators and Condensers independently developed by Kaidi adopt optimized heat exchange tube arrangement, which increases the contact area between refrigerant and medium by 20%, effectively improving heat exchange efficiency.
