When the chiller is used in various industrial equipment, the circulating cooling water is used to cool and cool the industrial equipment to ensure the stable and safe operation of the equipment. Today we will continue to talk about the differences between air-cooled chillers and water-cooled chillers.
The air-cooled chiller relies on the electric fan on the top to dissipate heat, and has requirements for the environment: such as ventilation, humidity, the temperature cannot be higher than 40°C, the pH value of the air, etc., while the water-cooled chiller needs to use the water tower umbrella water for heat dissipation.
There are four universal wheels at the bottom of the air-cooled chiller, which can be moved easily and reduce the floor space. The water-cooled chiller needs to be connected to a cooling tower before it can be used. Therefore, the water-cooled chiller occupies a large area and needs to provide a machine room, and water-cooled chillers must be placed indoors.
The shell-and-tube condenser used in the water-cooled chiller has a small impact on the heat exchange efficiency within a certain range of dirt accumulation, so the performance of the unit will decrease slightly with the generation of dirt, the cleaning cycle will be longer, and the relative maintenance cost will be low. However, the heat exchange efficiency of the finned condenser used in the air-cooled chiller is greatly affected by the accumulation of dust and dirt. The dust filter grid must be installed before the cooling finned tube, and it needs to be cleaned frequently.
Due to the high operating pressure of the air-cooled chiller, it is generally installed outdoors, and the operating environment is relatively harsh, and it is not as good as the water-cooled chiller in terms of maintainability and reliability. If the machine has problems with alarm or convenient temperature control, it is necessary to send an engineer to the door to check, and quote and repair according to the on-site situation, so the maintenance cost of water-cooled chiller and air-cooled chiller also depends on the specific situation.
Both air-cooled chillers and water-cooled chillers are more choices in the industrial refrigeration industry. If you choose a chiller in an actual factory, you still need to use different environments, temperature control ranges, required cooling capacity, heat dissipation, etc. All factors to consider whether to choose an air-cooled chiller or a water-cooled chiller.
