Calculation and engineering analysis of air cooling units
Air cooling units are an indispensable element of any industrial facility where heat exchange processes are an integral element of the production cycle. They provide the optimal temperature of the working medium for carrying out any operations related either to changing the aggregate state of the substance, or to “fitting” it to certain parameters. Of course, in order to achieve the maximum accuracy of the required indicators, it is necessary to carry out complex technological processes that are provided by the operation of air cooling units. The calculation and engineering analysis of air cooling units is a critical procedure that can guarantee the proper efficiency of such equipment.
What is the calculation of air cooling units and its methodology?
The calculation of the air cooling units is a very voluminous engineering evaluation aimed at identifying the parameters necessary for the operation of the equipment. They are represented by calculations that are carried out in order to identify the necessary design from the preliminary block configuration.
In addition, during the work, information is revealed regarding the functioning of air cooling units in certain conditions. It can be extremely important when using certain working environments, within harsh climatic conditions, special operating modes, and so on.
Why do you need to calculate and evaluate air cooling units?
The primary task pursued in the calculation and engineering analysis of the air cooling units is to obtain the necessary data that will be required to assemble its structure that has sufficient technical characteristics to carry out a certain heat exchange process.
When calculating air cooling units, first of all, the main parameters are taken into account – performance, design temperature and pressure. The choice of the material of the heat exchanger tubes is of great importance. It depends on the coolant.
Also pay attention to the volume of the inner contour, its weight and size characteristics, heat transfer surface area and some other aspects.
A well-conducted engineering calculation will provide the company with a machine whose work will meet all the requirements set out in the terms of reference.
Factors that are taken into account when calculating and engineering analysis of air cooling units
- First of all, pay attention to the type of pipes. Their diameter and manufacturing material are selected based on the properties and temperature of the working medium. We must not forget about the corrosive properties of the substance.
- The second most important is the air flow, due to which the main function of the air cooling unit is provided. The calculation is carried out as follows — to obtain a uniform air flow, the fan area should not be less than a half of the heat exchange section.
- The flow rate is also an important value. It should be selected in such a way as to ensure balanced heat transfer and pressure drop indicators.
- The ambient temperature directly affects the air cooling units’ operation. In order to minimize its negative impact, the average values characteristic of the air temperature in the summer are taken. The larger the value of this parameter, the larger the size of the heat exchange unit.
Why should the calculation of air cooling units be carried out only by qualified specialists?
The answer to this question is very simple. The calculation of the air cooling unit is a multi-stage and complex procedure, the implementation of which involves a huge amount of measurements, development and drafting the drawings.
At the same time, consideration of external environmental factors is of great importance. This parameter can radically change the performance indicators of equipment. That is why they need to be taken into account in advance.
The procedure for carrying out these works has a strict sequence, and each stage is characterized by a certain order of actions, which is strictly prohibited to violate.
Consequences of incorrect calculation and engineering analysis of air cooling units
An improperly performed calculation and engineering analysis of air cooling units will certainly entail a negative outcome, which can have a variety of consequences depending on the type of working environment and production.
Violations of the heat exchange process are the only problem due to the errors in the calculation of air cooling units, but it can lead to catastrophic difficulties. It’s obvious that the unit construction requires quite significant costs.
Building a device from scratch, as well as adjusting all communications to it, is also an additional waste of time, which again results in financial losses. In addition, there is a possibility of accidents at work, which can provoke much more terrible consequences.
The calculating procedure for air cooling units
This procedure is presented in several stages. Initially, as a rule, a preliminary configuration of the equipment is selected, which is best suited for performing the assigned tasks.
The method of calculation and engineering analysis of the air cooling units may vary depending on the pre-selected type of device, environmental conditions, as well as many other factors.
Hydraulic calculation of air cooling units
Hydraulic calculation of air cooling units is a procedure whose ultimate task is to identify the power costs for pumping coolant through pipes, since part of it is spent on overcoming linear and local hydraulic resistance.
The procedure for the conduct of calculations varies depending on the type of working medium. It will be different for liquid and gas.
What difficulties does the air coolers’ calculation process involve?
The main challenges lie in the process of carrying out engineering calculations. But there will be no problems in this matter for a qualified specialist. Production and calculation of air cooling units is performed in accordance with the Russian National Standard No.R 51364-99.
