Air-Cooled Chillers The Perfect Accessories for Your Industrial Cooling Requirements

Equipment Description:

1. Equipment Overview

Air-cooled chillers use air heat dissipation as the core cooling method, and use compressors to drive refrigerant circulation to cool normal temperature water into process chilled water. Its features include no need to install cooling towers, flexible installation, and adaptability to water shortage scenarios. It is widely used in industrial fields such as plastic molding, electronic manufacturing, and chemical cooling.

2. Technical Parameters

3. Operation mode and energy-saving characteristics

1. Conventional cooling mode: In summer, compressor cooling is used to meet high load requirements.

2. Natural cooling mode (FREECOOLING): Transition season: Use cold air to pre-cool the chilled water, and the insufficient part is supplemented by the compressor, reducing energy consumption by 30%-50%.

Winter: Completely rely on natural cold air cooling, the compressor is shut down, and only the fan operation power consumption is required.

4. Installation and maintenance precautions

1. Installation environment: Good ventilation is required to avoid radiator blockage, and outdoor installation is recommended.

2. Wiring specifications: The three-phase power supply must match the phase, and the grounding protection must be reliable.

3. Heat dissipation maintenance: Clean the dust on the condenser fins regularly to ensure heat dissipation efficiency.

4. Antifreeze protection: When the ambient temperature is below 0℃, the antifreeze circulation must be started or the water tank must be emptied.

5. Application areas

Plastic machinery: Cooling molds, improving the surface finish of products, and reducing shrinkage and deformation.
‌Electronic manufacturing‌: Precision temperature control in laser equipment and semiconductor production‌.
‌Chemical reactor‌: Control reaction temperature and ensure process stability‌.
‌Medical storage‌: Low temperature cold storage, cooling of biological agents‌.

Main structures and components

1. Core Refrigeration Components

1. Compressor

Function: compress low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gas to drive the refrigeration cycle.

Type: fully enclosed piston, screw or scroll compressor to meet different power requirements.

2. Condenser

Structure: finned heat exchanger, forced air cooling by fan to condense high-temperature gaseous refrigerant into liquid.

Cooling maintenance: fin dust needs to be cleaned regularly to ensure heat dissipation efficiency.

3. Evaporator

Function: liquid refrigerant absorbs heat and vaporizes in the evaporator, absorbing the heat of chilled water to achieve refrigeration.

Type: shell and tube or plate structure, directly exchange heat with chilled water.

4. Expansion valve

Function: throttling and reducing pressure, converting high-pressure liquid refrigerant into low-temperature and low-pressure wet vapor, entering the evaporator to absorb heat.

2. Auxiliary components‌
‌1. Fan‌ Forces air circulation to provide efficient heat dissipation for the condenser.
‌2. Filter device‌
‌ Dry filter‌: Filter impurities and moisture in the refrigerant to prevent system clogging.
‌Oil filter‌: Filter impurities in the compressor lubrication system to protect the oil pump.
‌3. Sight glass‌
Observe the flow state of the refrigerant and the water content of the system.

3. Water circulation system‌
‌1. Water pump‌
Drives the chilled water circulation to deliver the cooled cold water to the user end.
‌2. Water tank‌
Stores chilled water and balances the system pressure. Some models integrate temperature sensors.

4. Control system‌
‌1. Electronic control module‌
Integrates temperature controller and pressure protection device to achieve automatic start and stop and fault alarm.

Supports multi-mode adjustment (such as cooling/heating switching).
‌2. Sensor‌
Monitors parameters such as water temperature, pressure, and current to ensure operational stability.

5. Other structures‌
‌1. The frame and shell are made of rust-proof materials (such as galvanized steel plates), with a protection level of IP54, suitable for outdoor installation‌.
‌2. The lubrication system has a built-in oil pump, oil level sight glass and oil pipeline to ensure long-term stable operation of the compressor‌.
