Scroll Chiller

What Is A Scroll Chiller?

• Definition: ChillerOne scroll chiller is a cooling device with a scroll compressor as its core refrigeration component. It compresses the refrigerant through its unique internal spiral scroll structure, thereby continuously providing stable chilled water for industrial processes. It has the remarkable advantages of compact structure, smooth operation, long service life and high energy efficiency, which is widely used in industrial and commercial fields.
• Working Principle: The core working principle of the ChillerOne scroll chiller lies in the meshing of a stationary disk and a moving disk within the scroll compressor to form a series of continuously moving and shrinking compression chambers towards the center. Refrigerant gas is continuously drawn into these chambers. As it moves towards the center, it is compressed into a high-temperature and high-pressure state. Then it is discharged and undergoes condensation, throttling and evaporation processes. Eventually, it absorbs the heat of the circulating water at the evaporator, thereby achieving the continuous production of chilled water.

Core Components of the Scroll Chiller

Scroll Compressor

The scroll compressor forms a compression chamber that continuously moves towards the center and its volume keeps shrinking through the meshing of the fixed plate and the moving plate. These continuously compressed cavities efficiently and smoothly compress the refrigerant gas to a high-temperature and high-pressure state.

Condenser

The condenser receives high-temperature and high-pressure refrigerant gas from the compressor. Under normal circumstances, the condenser removes the heat it carries by using an external cooling medium, causing the refrigerant to condense into a liquid state.

Evaporator

The evaporator is a key component for heat exchange between the refrigerant and water. The liquid refrigerant absorbs the heat of the chilled water flowing through the evaporator and evaporates into a gaseous state, simultaneously cooling the chilled water, thus providing a cold source for the outside world.

Expansion Valve

The expansion valve rapidly reduces the cross-sectional area of the flow channel, causing the high-pressure liquid refrigerant to throttle and depressurize, transforming it into a low-temperature and low-pressure mist-like gas-liquid mixture, which laid the foundation for its heat absorption and evaporation in the evaporator.

Drier Filter

The drying filter is responsible for filtering out solid impurities that may exist in the refrigerant circulation and uses desiccants to absorb trace amounts of moisture in the system, which prevents ice blockage or corrosion in the system and ensures the safe operation of your equipment.

Features and Advantages of Scroll Chillers

High Energy Efficiency

The scroll chiller itself is highly efficient. Coupled with its continuous compression method, its energy-saving effect is remarkable.

High Reliability

Our scroll chiller has few moving parts, a simple mechanical structure and minimal wear, which fundamentally enhances reliability and extends the service life of the entire machine.

Low Noise

Due to the continuous compression and excellent dynamic balance of the scroll chiller, the noise and vibration levels during operation are much lower than those of piston and other models, which creates a more comfortable environment for you.

Compact Structure

Our scroll chiller is compactly designed and occupies a small area. Its daily maintenance mainly focuses on cleaning the filter screen and heat exchanger, significantly reducing your maintenance costs and time.

Precise Control System

ChillerOne scroll chiller integrates a precise control system to achieve accurate control of parameters such as temperature, pressure and flow rate, as well as monitoring of operational status, which is equipped with multiple safety protection functions.

Flexible System Configuration

Especially in the medium cooling capacity range, we generally adopt the multi-compressor parallel technology, which enables a single unit to have the characteristics of a wide cooling capacity adjustment range, strong backup capacity and high energy efficiency.

How to Choose the Right Scroll Chiller for Your Project?

Clarify Your Needs

• Cooling Capacity: You need to precisely calculate the total heat to be carried away through process parameters such as the power of the equipment, the specific heat capacity of the product, flow rate, and temperature variation. We suggest that you add a margin of 10% to 20% to the calculated total cooling capacity to deal with potential future load increases or calculation errors.
• Temperature: The lower the required outlet water temperature, the higher the requirements and cost for the unit. In addition, the greater the temperature difference, the smaller the water flow required for the same cooling capacity, but you may need a more special chiller configuration.

Select the Condensation Method

• Air-Cooled Type: If your installation site has limited water resources, but has good ventilation and sufficient space to place the unit, and you want a low initial investment and easy installation, I recommend you choose an air cooled scroll chiller. However, its drawback is that its energy efficiency is slightly lower, and the operating noise and heat dissipation may affect the surrounding environment.
• Water-Cooled Type: If you have extremely high requirements for energy efficiency, limited installation space or strict requirements for noise, I recommend you choose a water-cooled scroll chiller. Its drawback is that the initial investment is higher. You need additional cooling towers, water pumps and water treatment systems, and the maintenance is more complicated.

Auxiliary Function

• Control System: You should choose a model equipped with an accurate control system, which can achieve precise temperature control, display of operating parameters, fault alarm, etc.
• Protection System: You need to confirm that the unit has complete protection functions, such as high and low pressure protection, anti-freezing protection, water flow protection, etc.
