The design of the diffuser is obviously different from the grille HVAC. It’s either square shape or round shape when the grille HVAC is normally rectangle shape. Besides, the blades of the diffuser are fixed in most models, but the blades of the grilles is removable or adjustable in most models. The function of the HVAC diffuser is normally supplied air while the HVAC grille is returning air. The HVAC diffuser volume is much more than the HVAC grille. The diffuser is usually installed in the ceiling. The grille is normally installed both in the ceiling and on the wall.
Precautions for installation of air conditioner vent: Do not set the lamp slot at the air outlet of the air conditioner. It is easy to block the hot air from reaching the personnel activity area, affecting the heating effect. According to experience and test data, when heating in winter, the horizontal shutter is adjusted to 45 degrees, which is a suitable angle. If it is too high or too low, the heating effect may be affected. The air outlet of the air conditioner is large and easy to accumulates dirt, which affects the air outlet temperature and beauty of the air conditioner. Users should clean the air outlet regularly to keep it clean and ventilated.
The special-shaped louver vent is a kind of air distributor. In air conditioning engineering, various types of air supply outlets and return outlets (or exhaust outlets) are generally referred to as air distributors. Common louver HVAC diffusers include single-layer louver HVAC diffusers, double-layer louver HVAC diffusers, side wall grille HVAC diffusers, and slot grille HVAC diffusers. Single-layer louver HVAC diffusers are often used for return HVAC diffusers, sometimes with an aluminum alloy mesh filter or nylon filter screen. The double-layer louver HVAC diffusers are composed of double-layer blades. The front layer of the blades is adjustable, and the back layer of the blades is fixed. The opposite multi-blade air volume regulating valve can be configured as required to regulate the air volume of the HVAC diffusers. Find extra information at chinaventech.com.
