Water-Cooled Chillers with Environmentally Friendly Refrigerant Options Accessories

Equipment Description:

1. Equipment Overview

Water-cooled chillers are industrial refrigeration equipment that uses cooling water circulation to dissipate heat. They use compressors to drive refrigerant circulation to cool normal temperature water to process chilled water. They use water-cooled condensers and require a cooling tower for heat dissipation. They have the characteristics of high cooling efficiency and stable operation, and are suitable for high-load scenarios such as central air-conditioning systems, precision manufacturing, and chemical cooling.

3. Operation process ‌

‌1. Refrigeration cycle‌: compressor compresses refrigerant → condenser liquefies → expansion valve throttles → evaporator absorbs heat → circulation‌.
‌2. Water cycle linkage‌: chilled water and cooling water flow synchronously, and heat is discharged to the atmosphere through the cooling tower‌.

‌4. Installation and maintenance‌
‌1. Installation requirements‌ The vertical height difference between the cooling tower and the unit is ≤5m, and the pipeline needs to be insulated to prevent condensation‌.
The cooling water system needs to be equipped with a filter device to prevent impurities from entering the condenser‌.
‌2. Maintenance points‌ Condenser/evaporator‌: Chemical cleaning and descaling every year to ensure heat exchange efficiency‌.
‌Lubricating oil‌: Check the oil quality and replace it every 4000 hours‌.
‌Electronic control system‌: Regularly check the sensor accuracy and protection device sensitivity‌.

5. Application areas‌
‌Central air conditioning‌: Temperature control of commercial buildings, hospitals, and hotels‌.
‌Industrial cooling‌: Cooling of injection molds and temperature control of laser equipment‌. ‌Chemical and pharmaceutical industries: reactor temperature control and low-temperature storage.

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: Screw compressor: compresses refrigerant through screw rotation, suitable for medium and large units.

Centrifugal compressor: uses high-speed rotation of the impeller to generate centrifugal force, with high efficiency and suitable for high-power scenarios.

2. Condenser

Structure: Water-cooled shell and tube heat exchanger, high-temperature and high-pressure refrigerant exchanges heat with cooling water and condenses into liquid.

Cooling method: Cooling water circulates through the cooling tower to dissipate heat, or directly exchanges heat with natural water sources.

3. Evaporator

Function: Liquid refrigerant absorbs the heat of chilled water and evaporates into gas to achieve refrigeration.

Type: Shell and tube evaporator: refrigerant evaporates in the tube, and chilled water flows outside the tube.

Water tank coil type: refrigerant coil is immersed in the chilled water tank for direct contact heat exchange.
‌4. Expansion valve‌
‌Function‌: throttling and reducing pressure, converting high-pressure liquid refrigerant into low-temperature and low-pressure wet steam‌.
‌Type‌: thermal expansion valve (external balanced) or electronic expansion valve, precise flow adjustment‌.

‌2. Auxiliary components‌
‌1. Dry filter‌
Filter impurities and moisture in the refrigerant to prevent system blockage‌.
‌2. Oil separator‌
Separate the refrigerant and lubricating oil discharged from the compressor to ensure that the lubricating oil flows back to the compressor‌.
‌3. Sight glass‌
Observe the flow state of the refrigerant and the water content of the system‌.
‌4. Safety protection device‌
Including high and low pressure protection, overload protection, antifreeze protection, etc., to ensure stable operation of the system‌.

3. Water circulation system‌
‌1. Chilled water circulation‌
‌Water pump‌: drives the chilled water to circulate between the evaporator and the user end‌.
‌Chiller tank‌: Stores chilled water and balances the system pressure‌.
‌2. Cooling water circulation‌
‌Cooling tower‌: Reduce the cooling water temperature by evaporating water to maintain condensation efficiency‌.
‌Cooling water pump‌: Push the cooling water to circulate between the condenser and the cooling tower‌.

4. Control system‌
‌1. Electronic control module‌
Integrate PLC or microprocessor to achieve automatic adjustment and fault diagnosis of temperature, pressure and flow‌.
Support multi-mode operation (such as variable frequency speed regulation, energy-saving mode)‌.
‌2. Sensors and instruments‌
Monitor parameters such as water temperature, pressure, current, etc., and provide real-time feedback to the control center‌.
