The main difference between air-cooled chillers and water-cooled chillers

First of all, it is necessary to find out which types of chillers are divided into: General manufacturers will produce two types of water-cooled and air-cooled chillers.

The air-cooled chiller contains a heat preservation water tank and a water pump in its body, so there is no need to add a cooling water tower to dissipate heat. It is very convenient to install and move. But it has higher requirements for the working environment. First of all, because it uses hot air circulation It is refrigerated, so if the ventilation effect of the installation workshop is not good, it will directly affect the cooling effect of the chiller. In addition, if you want to put the chiller in a dust-free workshop with humidity requirements, then I advise you to modify it Water-cooled. Because the air-cooled chiller will spray water vapor on the top of the machine to dissipate heat.

　　 water-cooled chillers can be divided into open type, sealed type (some called box type) and screw type. First of all, it must be stated that for water-cooled chillers, additional cooling towers and pumps must be installed to extract hot water for heat dissipation. In order to achieve effective cooling effect.

The open type chiller needs to be equipped with a water tank. The sealed type is not necessary because it has a built-in water tank. The open type is usually installed somewhere outside the workshop. It is convenient for maintenance, but because it is not beautiful enough, it is A sealed water-cooled chiller was produced, which is more popular because it is a box structure. But if you have very high requirements for cooling capacity, you must choose a screw-type chiller. At this time, we generally call it a chiller.

　　 Air-cooled chillers can be used in small systems, and most of the large units are water-cooled. The initial investment of water cooling is a little less than that of air cooling in terms of the main engine. But with the addition of cooling towers and computer rooms\electronic water treatment equipment, there is not much to go! Besides, in terms of long-term operation, the cooling of water-cooled units The efficiency will drop relatively, and the air cooling will not. The air-cooled chiller adopts the air cooling method, eliminating the need for cooling towers, cooling water pumps and piping systems necessary for cooling water systems, avoiding condenser fouling and water pipe blockage in areas with poor water quality, and also saving water resources. It is the most economical and simple model for maintenance and repair among current cold water air-conditioning equipment products. The one-time investment of air-cooled chillers is slightly higher than that of water-cooled chillers, but the annual operating cost is lower than that of water-cooled chillers. The construction cost of the computer room is the least among various air-conditioning cold and heat source systems, and the maintenance cost is about water-cooled Half the cost of the type or boiler. The noise and volume of air-cooled chillers are larger than those of water-cooled chillers, so they can only be installed outdoors. Most water-cooled units are installed in basements.
