Industry knowledge
With the booming development of cold chain logistics, food processing, pharmaceutical storage and other industries, the demand for high-efficiency, energy-saving and stable refrigeration equipment is surging. As a core component of the refrigeration system, Condensing Units, Coolers, Evaporative Condensers, Evaporators and Condensers, and Pressure Vessels directly determine the operation efficiency and stability of the entire system. Zhejiang Kaidi Refrigeration Equipment Co., Ltd., a professional refrigeration enterprise with nearly 30 years of experience, has been committed to providing high-quality refrigeration equipment and overall solutions for global customers, and its products have been widely recognized by well-known enterprises such as GLP, SF Express, JD.com and Yaleng.


1. Basic Cognition: Core Definition of Key Products

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

The quality of refrigeration equipment is measured by a series of core technical indicators. Kaidi Refrigeration focuses on these indicators and continuously optimizes product performance through R&D and innovation.

2.1 Key Performance Indicators of Core Products

Technical Indicator Definition Significance Kaidi Product Performance Data
Heat Exchange Efficiency The ratio of actual heat exchange capacity to theoretical heat exchange capacity Determines the refrigeration speed and energy consumption of the equipment Evaporative Condensers: ≥95%; Evaporators and Condensers: ≥92%
Energy Efficiency Ratio (EER) Ratio of cooling capacity to input power The higher the value, the more energy-saving the equipment Condensing Units: EER ≥ 3.8 (under rated working conditions)
Operating Pressure Stability The fluctuation range of internal pressure of equipment during operation Affects the service life and safety of equipment Pressure Vessels: pressure fluctuation ≤ ±0.02MPa; Condensing Units: stable pressure operation within rated range
Corrosion Resistance The ability of equipment to resist corrosion by media such as refrigerant and water Determines the service life in harsh environments Coolers: anti-corrosion coating treatment, service life extended by 30% compared with ordinary products

2.2 Core Technical Principles (Simplified Schematic)

Refrigeration Cycle Principle of Evaporators and Condensers

  1. Evaporation Stage: Liquid refrigerant enters the Evaporator, absorbs heat from the cooled medium and vaporizes, turning into low-pressure vapor.
  2. Compression Stage: The compressor in the Condensing Unit compresses the low-pressure vapor into high-pressure high-temperature vapor.
  3. 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.
  4. 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.

3. Industry Trends: Development Direction & Product Advantages of Kaidi

With the global emphasis on energy conservation, environmental protection and intelligent manufacturing, the refrigeration equipment industry is showing three major development trends, and Kaidi Refrigeration's products are precisely aligned with these trends.

3.1 Industry Upgrade Direction
