High-Performance Accessories for Energy- and Durable Refrigeration Equipment with Intelligent Control

Equipment Description:

I. Working Principle
Refrigeration Cycle: Based on the reverse Carnot cycle, heat exchange is achieved through refrigerant phase change (evaporation absorbs heat → compression increases pressure → condensation releases heat → throttling reduces pressure), maintaining the plating bath temperature within a range of 5-30°C.
Two-Stage Refrigeration (Optional): A two-stage compression system improves energy efficiency under low-temperature conditions and is suitable for applications with large temperature fluctuations.

II. Equipment Features
1. Corrosion-Resistant Design
The evaporator and piping are made of titanium alloy or stainless steel, resistant to acid and alkali corrosion from the plating solution.
The circulation pump uses a corrosion-resistant chemical pump to ensure long-term stable operation.
2. Intelligent Control
The integrated PLC control module supports temperature adjustment with ±1°C accuracy and displays operating parameters and fault alarms in real time.
It features a flow protection function that automatically cuts off the power supply in the event of water shortage to prevent equipment damage.
3. Energy Efficiency
The hot air circulation system reduces heat waste, and the water-cooled unit can save over 30% energy compared to traditional equipment.
The variable-frequency speed-controlled compressor dynamically adjusts power according to load, reducing energy consumption.

III. Application Scenarios
Electroplating: Controlling plating bath temperature to improve coating uniformity and adhesion, and reducing metal ion precipitation.
Anodizing: Precisely cooling the oxidation tank solution to prevent overheating and film loosening.
Chemical/Electronics: Laboratory temperature control, reactor cooling, etc.

IV. Technical Parameter Examples

V. Selection and Maintenance Key Points

‌1. Selection Guide‌
Select a model with a suitable cooling capacity based on the plating tank volume, target temperature drop, and environmental conditions.

Preferably, a modular design facilitates future expansion and maintenance.
‌2. Maintenance Requirements‌
Regularly clean the condenser from scale and fin dust to ensure efficient heat dissipation.

Check the refrigerant pressure monthly and refill or replace it promptly.

Main structures and components:

I. Core Refrigeration Cycle Components

1. Compressor

Using a scroll or screw design, this compressor compresses low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas, powering the refrigeration cycle.

Some models are equipped with variable frequency drive (VFD) to dynamically adjust power based on load to reduce energy consumption.
2. Evaporator

Directly exchanges heat with the plating solution, absorbing heat through refrigerant evaporation. Materials must be resistant to acid and alkali corrosion (such as titanium alloy, PVC, or stainless steel).
Common types include shell-and-tube or plate heat exchangers, adapting to the flow requirements of different plating baths.
3. Condenser

Cools high-temperature, high-pressure gaseous refrigerant into liquid. These are primarily water-cooled (relying on circulating water from a cooling tower) or air-cooled (using fins and a fan to dissipate heat).
Water-cooled condensation is more efficient, but requires maintenance of a cooling water system.
4. Expansion Valve (Throttle Valve)

Controls refrigerant flow and reduces pressure, ensuring sufficient evaporation and heat absorption after the liquid refrigerant enters the evaporator. Common types include thermal expansion valves and electronic expansion valves, the latter offering higher precision.

II. Auxiliary System Components
1. Circulation Pump
This chemically corrosion-resistant pump circulates the plating solution through the evaporator, achieving continuous heat exchange.
2. Filter Drier
This absorbs moisture and impurities from the refrigerant, preventing icing or blockage within the system.
3. Control System
An integrated PLC controller monitors temperature (±1°C accuracy), pressure, and flow, supporting automatic alarms and protective shutdowns.
4. Liquid Storage Tank
This stores excess refrigerant and balances pressure fluctuations within the system.

III. Special Design Features
Corrosion Resistance: The evaporator, piping, and circulation pump are constructed of materials such as titanium alloy to withstand the highly acidic and alkaline environment of the plating solution.
Efficient Heat Exchange: The evaporator and condenser utilize enhanced heat transfer designs (such as bellows and fin structures) to improve cooling efficiency.
Modular Configuration: This system supports parallel operation of multiple units to meet the cooling needs of large-scale electroplating production.
