In many factories or laboratories, industrial chillers play an important role. It can provide the required low temperature environment for production and testing, thus ensuring the smooth progress of production and testing. However, there are quite a lot of types and models of the unit on the market, and many users are troubled by the selection. Today we will introduce the three major steps in the selection of the unit.

1. It is necessary to determine the range of cooling capacity:

When calculating the cooling capacity, the user can calculate it according to the temperature difference between the cooling water inlet temperature and the outlet temperature. The cooling capacity can also be calculated through the power and calorific value of the equipment through the formula.

The commonly used calculation formula is: cooling capacity = chilled water flow * temperature difference * specific heat * coefficient

In order to ensure sufficient cooling effect during use, the theoretical cooling capacity parameters can be increased by 20% during actual model selection.

2. Consider the use of environmental factors:

At present, there are two types of units on the market: air-cooled and water-cooled. When determining air-cooled and water-cooled, the factor of the use environment needs to be considered. If the environment used is not well ventilated, you can choose a water-cooled unit. When the unit is running, it needs to rely on fans to dissipate heat into the atmosphere. Once the gout is not good in the occasion of use, it will cause poor heat loss and the cooling efficiency will decrease.

The water-cooled unit uses an external water tower to dissipate heat, even if the ventilation is poor, it will not affect the cooling effect. However, if the environment used is short of water and dry, but the environment is well ventilated, then you can choose an air-cooled unit, which is relatively simple to install and easy to maintain.

3. Combined with the actual engineering situation:

It needs to be selected according to the actual engineering situation. The current factories are equipped with cooling water towers. In addition to their own actual conditions, water-cooled units can be selected by connecting the water towers through pipelines. If the factory itself is not equipped with water towers, it needs to be considered. The space for installing the water tower, because the installation of the water tower needs to occupy a certain space, if the project itself is small, and the space configuration of the workshop is limited, you can choose the air-cooled unit.

In addition, the user can also select the model according to the characteristics of the production process, especially some users have special requirements for the performance of the unit such as explosion-proof, rust-proof, corrosion resistance, acid and alkali resistance, etc. material so that the established process requirements can be met. Even because of the particularity of the use occasion, it is necessary to put forward customized requirements to the manufacturer.

It can be seen that the seemingly simple selection of industrial chillers hides a lot of knowledge. At the same time, it is necessary to pay attention to the quality and configuration of the unit. Quality and configuration can be said to be the key to the operation of the entire cooling system. Once the user Improper selection may bring unnecessary troubles to future use. In order to choose a satisfactory unit, you may wish to compare the selection schemes when purchasing, and find the unit that is suitable for actual production needs.
