When selecting and purchasing fan coil units, besides the quality and price of fan coil units, the selection of fan coil unit model is the most important item. If the fan coil unit model is selected incorrectly, then the quality of fan coil units is no matter how good it is, it cannot meet the ideal requirements. Therefore, the selection of fan coil unit model can be said to be a very important item in selecting and purchasing fan coil units.
FCU type selection is just like choosing clothes. In summer, it is definitely against the rules for us to choose a sweater. It is definitely not possible to choose XL or S size clothes for M body type. It is also not possible to choose a small election or the wrong type. The same is true for fcu type selection.
When buying clothes, at least we can try them on realistically, but not fan coil units, so how should we choose the fan coil unit model?
The model selection of fan coil unit mainly refers to these 4 main factors:
1. The most basic function of fcu is cooling. The biggest function of fcu is also cooling. Therefore, cooling capacity is the most important basis for fcu model selection. When selecting the cooling capacity of fcu, attention should be paid to the actual working conditions of the space. If there is a fresh air system in the room, and the fresh air system is sent to the room directly through the outer wall without passing through any heat temperature. At this time, the cooling capacity of fcu = indoor cooling load fresh air cooling load. If there is an independent fresh air system designed in the room, then the refrigerating capacity of fcu = indoor cooling load.
2. The selection of fan coil unit model 2. The air flow of fcu is determined by the requirements of air exchange rate in space. The smaller the air supply temperature difference, the more air exchange rate, the more comfortable the indoor environment, and the better the air quality. Therefore, in order to achieve an ideal and comfortable indoor environment, the air volume value of this part must be deducted when calculating the air volume of fan coil unit.
3. Fcu model selection 3, return air mode.
4. Reasonable air distribution requires a certain air supply speed and also avoids short circuit of air flow. Strictly speaking, this is a fan coil unit system design problem.
Simply put, the basis for fan coil unit model selection is the cooling load and air volume. Both aspects can be calculated, and then it is sufficient to select the maximum value from these two values as the basis for fan coil unit model selection. This is also the best method.
