Water cooled chillers are more efficient especially for large cooling loadsThey use the evaporation of water to dissipate heat which is less energy intensive than air cooled chillersWater also has a higher heat capacity than air so its inherently easier to remove the heat.
A chiller system repair and maintenance checklist is used by manufacturing facility chiller operators and maintenance personnel to daily inspect different types of industrial chillers such as centrifugal screw reciprocating and absorptionEasily check an unlimited number of industrial chillers and take photos of detected defects or done.
After the industrial chiller system has passed the vacuum test the vacuum state in the system can be used to charge the refrigerant.
Apr 12 2021nbsp018332Spring maintenance is a perfect time to calibrate the sensors and controlsCheck electrical connections throughout the control cabinet and tighten or repair any that are looseEnsure all motor overloads are set according to each motor’s nameplate andor according to the unit’s wiring diagramClean the Condenser Coils AirCooled Chillers.
Apr 23 2020nbsp018332If the chiller is used for more than 6 months the dehumidifier or the high low pressure switch often fails or the cooling capacity is reducedThis requires professional maintenance personnel to repair itThe above are some ways to maintain industrial chillers.
Apr 23 2020nbsp018332Maintenance methods of industrial chillers The protection device settings of the industrial chiller unit have been set by the manufacturer and users should not modify it at willIf the chiller is used for more than 6 months the dehumidifier or the high low pressure switch often fails or the cooling capacity is reduced.
Aug 19 2020nbsp018332The industrial chiller main components contain Chilled water systems cooling systems terminal equipment and air conditioning units etcA Check the refrigerant system and the wiring to try to identify the cause of the compressor burnoutB To recover the refrigerant relevant equipment and tools should be.
1 Main parts maintenance and precautionsIn the process of operation should pay attention to exhaust and inhale pressure of the systemPls find out the reasons and trouble shooting if any anomaly immediatelyDon’t arbitrarily adjust the control and protective element set points.
Expansion device which creates a pressure drop that reduces the pressure of the refrigerant to that of the evaporatorThe resulting mixture of liquid and vapor refrigerant A travels to the evaporator to repeat the cycleThe components of th e absorption refrigeration cycle will be discussed in detail in a moment.
Expert specializing in industrial chiller machines for more than 10 years good at water cooling solutions in the energy aerospace automotive electronics manufacture processing medical industries etc.
For a given chiller as the leaving chilledwater temperature drops the refrigerant temperature and pressure must also dropConversely as the leaving chilledwater temperature rises so do the refrigerant temperature and pressureWhen the l eaving chilledwater temper ature changes the work a compressor must do also changes.

Industrial chillers are one type of chillers and chillers can be divided into aircooled chillers and watercooled chillersWater chiller is a kind of water cooling equipment which can provide constant temperature constant current and constant pressure cooling equipment.
Jan 18 2022nbsp018332Water Cooled Screw Chiller Maintenance Checklist Shutdown Inspection.
Mar 25 2022nbsp018332Monthly chiller maintenance checklistCommon monthly maintenance tasks to be performed on your chillers include Check components for wear and tearCheck the level of lubrication in the centrifugal pumps and motorsTop up the lubrication if requiredCheck the condenser and clean the coils.
May 28 2021nbsp018332The chilled water of the chiller takes away the heat and then the temperature rises and returns to the water tank to achieve the cooling effectThe cooling water temperature can be adjusted automatically according to the requirements and the longterm use can save waterTherefore the chiller is a standard energysaving equipment.
May 30 2008nbsp018332Re pressure drop and chillers Flow rate must be regulated closely because too low a flow rate reduces chiller efficiency leading to laminar flow which results in poor heat transfer and short cycling The minimum flow rate is typically around 3 ftHowever too high a flow rate leads to vibration noise and tube erosion.

Sep 07 2021nbsp018332The following is an analysis of the Industrial Chiller LowPressure AlarmFilter drier dirty plug or copper pipe oil plugIf the solenoid valve is not open the lowpressure will gradually drop until the lowpressure alarm is generated in the air conditioning control panel for alarm reset low pressure will not rise again at this.
Sep 25 2020nbsp018332The pressure drop on the evaporator side of the valve makes the refrigerant flash off into a cold saturation point liquid and vapour mixThe liquid boils off absorbing latent heat through the inside of the copper tubesOn the outside of the copper tubes is the return water from the process or the cooling of buildings.
The poor cooling effect of the chiller means that the chiller can be normally operated but it can’t cool down the setting temperature under the specified working conditionsAdding too much refrigerant after maintenance 3There is air in the refrigeration system 4.
The pressure differential is typically less than 10 psi for a system with clean filter drier coreReplace the filter drier core if the pressure drop is greater than 10 psi or during the annual preventive maintenance schedule whichever comes first.
Choose the suitable maintenance method for the industrial water chiller groupThe aircooled industrial water chiller unit should be turned on according to whether the direction of the fan is correct.
