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.
2. Technical Parameters
| Item | Parameter Description |
| Cooling capacity range | 50kW-5000kW (screw type) |
| Input power | 380V/50Hz (three-phase) |
| Refrigerant type | R22, R134a, R407c (environmentally friendly optional) |
| Cooling water requirement | Water temperature ≤32℃, flow rate is matched according to power |
| Energy efficiency ratio (COP) | 4.5-6.5 (full load condition) |
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.
5. Technical parameters
