The long -range air -conditioning unit is different from ordinary hanging air -conditioning units. This air -conditioning unit is not connected and is mainly used for direct air supply.
The thermal load calculation of the long -range air conditioner unit is the same as that of ordinary air -conditioning units.Due to the energy saving of this technology, it can be appropriately reduced when designing the value; the selection of the performance parameters of the equipment thermal work is similar to that of ordinary air -conditioning units.
When using this technology, the main content of the design selection calculation is the calculation of the airflow tissue.For a certain building, when the air supply distance, the installation height of the air -conditioning unit, the air supply temperature, the indoor temperature, and the amount of air delivery are roughly determined, you need to choose the appropriate remote air conditioning unit to make the hot and cold shot from the air outlet of the crew satisfied the following.Require:
1. The hot and cold wind is delivered to the specified location;
2. Cold shooting will not fall halfway, leading to uncomfortable human body;
3. The hot air can reach the required air supply distance and location;
4. The temperature difference at the end meets the design requirements.
When designing and selected, consider the mutual influence and common role of multiple crews.The diffusion width of the shot is roughly 0.4 times that of the range, and the unit layout density should be slightly smaller than the diffusion width.If the unit is close to the ceiling installation, the impact should be considered.The range of attached airflow is about 1.4 times that of general airflow.
Unit layout spacing
The larger coverage width of the spray airflow is about 0.3-0.6 times the range of the range. The unit layout should refer to factors such as airflow diffusion angle and air flow uniformity. The spacing should not be too large, and generally 0.4 can be selected.
Extension
The crew can choose unilateral layout, or a two -sided layout of the air supply.However, both buildings of different widths may not have enough range.
