Chiller is a commonly used water cooling equipment that can provide constant current, constant temperature and constant pressure. Chillers are mainly divided into water-cooled and air-cooled, which are further divided into:
water-cooled screw ，water cooled scroll chiller and air-cooled screw air cooled scroll chiller, Water-cooled centrifugal chiller.
The difference between air-cooled chillers and water-cooled chillers is mainly reflected in the following aspects:
1. Refrigeration is different
The water-cooled chiller mainly uses water as the cooling medium, which has good cooling effect and low noise. The air-cooled chiller mainly uses the wind as the cooling medium, the cooling effect is average, and there is noise.
Mainly used in areas with water scarcity or poor water quality.
Air-cooled chillers are equipped with cooling fans and finned condensers; water-cooled industrial chillers are equipped with water condensers, generally shell-and-tube condensers, and are generally used with cooling towers and
cooling water pumps.
2.initial investment
The necessary supporting facilities for air-cooled chillers are water separators, chilled water pumps and water collectors. However, the water-cooled chiller is a special machine room, a water collector, a cooling tower (cooling chilled water pump) and a water separator. Water-cooled chillers have several more necessary facilities than air-cooled chillers. Therefore, in terms of initial investment, air-cooled chillers are significantly higher than water-cooled chillers.
3.Performance comparison
The heat transfer temperature difference of the condenser of the water-cooled chiller is generally 4°C-8°C, while the heat transfer temperature difference of the air-cooled chiller is generally 8°C-15°C. The water temperature is lower than the outdoor air temperature, so the condensing temperature of the air-cooled chiller in normal operation is higher than that of the water-cooled chiller, so that the air-cooled chiller will consume less electricity under the same cooling capacity. Larger than water-cooled chillers.
4.Install and use
The installation of the air-cooled chiller is more convenient: the unit has been installed with a condensing fan, and there is no need for an external cooling tower or cooling water pump. Easy to move: Compared with the water-cooled type, there is no cooling water pipe, and the movement is flexible. According to the conditions of use, if the cooling tower cannot be installed at the installation site, only the air-cooled type can be used.
5.Operating costs
Because the water-cooled unit operates at a lower condensing temperature, the cooling efficiency is high, and the power consumption of the unit operation is small. Generally speaking, comparing the water-cooled chiller with the air-cooled unit with the same cooling capacity, the overall power consumption of the water-cooled unit is smaller than that of the air-cooled unit.
Since the air-cooled chiller relies on fans to dissipate heat, it has higher requirements on the surrounding environment such as ventilation, humidity and temperature. The water-cooled chiller runs more smoothly, with less loss of cooling capacity, easy to return oil, and the heat transfer tube is not easy to freeze and crack, and the energy efficiency is higher than that of the air-cooled machine. However, the water-cooled machine occupies a large area, and the price is much higher than that of the air-cooled machine. When choosing a chiller, you must consider objective environmental factors, choose the appropriate type, and then according to the cooling capacity
