Heat -intensive equipment of various types is used today everywhere. One of the most economical units is AVO (air cooling devices). This unit does not use any other coolants in the process of operation, except for air masses.
This puts it in an independent position from many factors: it is not necessary to organize an additional water supply, there is no risk of rampant plaque on the pipes and loss of thermal power as a result of this. . Therefore, the production of heat exchangers of this type is carried out on a large scale, especially with the development of numerous gas fields in our country.
When transporting gas, air cooling devices are used to increase the economic efficiency of this process. Gas during cooling decreases in volumes. Accordingly, you can transport more gas in a certain period of time through the pipeline of a certain diameter. At the moment, the economic efficiency of the entire gas delivery process to different geographical points depends on the effective operation of the AVO at the moment.
The calculation of air cooling devices at the design and production stage helps to increase the efficiency of the units themselves. When conducting calculations, all thermal loads on the unit are taken into account, including the ambient temperature. Do not forget that gas deposits are in climatic zones with extremely low and extremely high temperatures. Therefore, when designing, the highest and lowest temperature indicators are taken into account. And the power of the unit is laid taking into account the record seasonal temperatures. This means that during the period of the decline of extreme temperature values, the unit will work with increased power. This will lead to premature wear, and to the overspending of electricity.
Therefore, when designing, it is also necessary to take into account the ability to adjust the power of AVO in the period when temperature loads are not so high. It is possible to adjust the power of the AVO due to the alternation of the number of fans that control the intensity of the movement of the air masses inside the unit, and therefore the power of the unit itself. It is possible to provide automatic regulation of fan operations in order not to depend on the maintenance personnel and reduce the costs of attracting labor. Manual power regulation can also be provided. In any case, when designing, it is important to provide the most complete opportunity to control the power of the unit in order to increase its operational efficiency and profitability of use.
