HVAC—Installation specifications for air conditioning vents
When many carpenters are making suspended ceilings, they do not design the return air vent properly, and even seal the return air vent, which greatly affects the use effect of the air conditioner, and even greatly reduces the life of the air conditioner.
The air supply mode of the air outlet is divided into: side air supply and air duct air supply
Side air supply: This air supply method has relatively simple pipe layout and convenient construction. The louver air supply port is most commonly used to match it. Because the louvers are movable and adjustable, not only the air volume but also the direction can be adjusted. But not all room conditions and air-conditioning equipment are suitable for side air supply, so the same, the air duct air supply also has corresponding conditions and requirements.
Requirements characteristics of side air supply equipment:
The running sound is small, the body should be thin enough, and the equipment layout should be compact
The static pressure outside the indoor unit should not be too low
The return air mainly includes bottom return, side return or back return
Features of air duct air supply equipment requirements:
Can correspond to irregular viewing space and empty space
High static pressure outside the indoor unit
Can be connected to long-distance air ducts and various air outlets
Air supply mode: side-sent, down-sent and ground-sent. The return air way is connected to the side return or rear return of the air pipe.
Side delivery and return: The ceiling space is small, and the running noise is smaller. It can be matched with a bedroom with a long aisle at the entrance, so that it can make perfect use of the space next to the bathroom. The size of the inspection port is above 450mm*450mm
Side feed and bottom return: It is suitable for installation in rooms with insufficient ceiling space. The minimum space in the ceiling is 240mm, and the extension is at least 700mm. The size of the same inspection port needs to be more than 450mm*450mm
Side supply and side return: When the space does not allow the ceiling, place the air conditioner indoor unit in the full ceiling space of the bathroom or kitchen. There is no need for a ceiling in the room, and the space comfort will be better, but pay attention to the distance between the air supply and return air outlets.
Keep the distance between the air outlet and return air outlet at 1m or more and adjust the wind direction of the horizontal and vertical louvers to avoid air short circuit. Since the ceiling air return is used, most of the ceiling space will increase the air conditioning load, so it is necessary to make a small independent air return cavity in the ceiling. If the ceiling is in the kitchen or bathroom, it is necessary to take measures such as heat insulation, temperature insulation and oil fume prevention, and to avoid the exhaust system.
Whether it is a ducted machine or a central air conditioner, the air outlet of the air conditioner is roughly the same. As we all know, the air conditioner has two air outlets, one is the air outlet, and the other is the return air outlet. They cooperate with each other to recycle the air, so the air-conditioning wind is relatively soft.
There are many kinds of air outlets for air conditioners, and now there are conventional ones with a length of 1.2, which are integrated air outlets including return air and inspection ports, so that the upper and lower air outlets are the same length as the return air outlet, which is more coordinated and more beautiful.
It is not recommended to design the air supply outlet in the light trough, as the effect of the air conditioner will be compromised. The longer air outlet has two internal units, which is generally done in larger restaurants, so the air outlet needs to be integrated. It's more neat.
If there is only one air outlet, but the area is relatively large, the suspended ceiling will be very long. At this time, false air outlets can be designed to improve the aesthetics.
If it is impossible to install the side air outlet in the study or other places, then you can also install the lower air outlet, so that the top surface needs to be suspended flat, but the effect is still good, especially for heating.
Regardless of whether it is a central air conditioner or a ducted unit, the air outlets are the same. Do not separate the inspection port and the return air port, as this will be unsightly. It is recommended to make it integrated.
