JLSF-75D Air Cooled Water Chillers,Danfoss Scroll Compressor Stable Performance

Product Description:

The air-cooled scroll chiller is a chiller that uses a scroll compressor and air-cooled heat dissipation. It uses a scroll compressor to compress low-temperature refrigerant into high-temperature and high-pressure gas, and then dissipates the heat to the surrounding environment through an air-cooled radiator to achieve a cooling effect.

Scroll compressors are a high-efficiency, low-noise compressor type. Compared with traditional reciprocating compressors, scroll compressors have higher compression ratios and lower vibration noise. It uses a vortex-like rotating action to quickly compress and discharge the refrigerant, providing a high-pressure and high-flow refrigerant supply.

An air-cooled radiator is a cooling device that uses natural wind or fans to transfer heat to the surrounding environment. It usually consists of a heat sink and a fan. It takes away heat from the chiller and lowers the temperature through air blowing against the heat sink and convection heat transfer.

Production Features:

The main advantages of air-cooled scroll chillers include:

1. High efficiency and energy saving: It adopts scroll compressor, which has high compression efficiency and can provide higher refrigeration capacity and efficiency. At the same time, the air-cooled heat dissipation method avoids the water pumps and cooling towers of traditional water-cooling systems, reducing energy consumption and maintenance costs.

2. Flexibility and convenience: Since there is no need to connect to the cooling water source, the air-cooled scroll chiller is not restricted by the cooling water pipeline, and installation and debugging are relatively simple. It is suitable for various places, whether it is industrial production workshop or commercial office space.

3. Reliability and stability: The scroll compressor has a simple structure, which reduces the wear and failure rate of mechanical parts and improves the reliability of the system. At the same time, the air-cooled radiator does not rely on external cooling water sources, avoiding leakage and water quality problems that may occur in the water-cooling system.

4. Space saving: Since there is no need for cooling water tanks and cooling towers, air-cooled scroll chillers can save installation space and are especially suitable for places with limited space.

It should be noted that air-cooled scroll chillers may have a slight disadvantage in heat dissipation compared to water-cooled systems, especially under high ambient temperatures or high-load operating conditions. Therefore, when selecting a chiller, comprehensive considerations need to be made based on specific application requirements and environmental conditions.

Working Principle:

The working principle of the air-cooled scroll chiller is as follows:

1. Compression process: First, the scroll compressor starts working. The vortex rotor inside it draws low-temperature refrigerant into the compression chamber through self-rotating motion. The rotating motion of the vortex rotor causes the refrigerant to be compressed and increase its temperature and pressure.

2. Condensation process: High-temperature and high-pressure refrigerant is discharged from the scroll compressor and enters the air-cooled radiator (condenser). In an air-cooled radiator, the refrigerant passes through the heat sink and transfers heat to the surrounding environment through fan blowing and convection heat transfer, causing the refrigerant to cool and condense into a liquid.

3. Expansion process: The condensed refrigerant liquid enters the expansion valve (throttle device), which controls the flow and pressure of the refrigerant. Through the throttling effect of the expansion valve, the pressure and temperature of the refrigerant are reduced, preparing to enter the evaporator.

4. Evaporation process: Refrigerant enters the evaporator and flows in the evaporator pipe inside the evaporator. In the evaporator, the refrigerant absorbs heat from the external environment, causing the refrigerant to change from a liquid state to a vapor state. This process absorbs heat from the surrounding environment, thereby achieving a cooling effect.

5. Cycle process: The refrigerant is discharged from the evaporator in the form of steam, and is sucked into the scroll compressor again. After cyclic processes such as compression, condensation, expansion and evaporation, the refrigerant is continuously circulated to achieve a continuous cooling effect.

Through the compression effect of the scroll compressor and the heat dissipation effect of the air-cooled radiator, the air-cooled scroll chiller can take away heat from the object or system to be cooled, and supply the cooled water to the equipment or equipment that needs to be cooled. process to achieve the cooling effect. The entire system continuously operates through the above-mentioned cycle process to maintain a stable cooling effect.
