Air filtration box and air heat recovery box

An air filtration box and an air heat recovery box are two common air handling devices used to improve indoor air quality and enhance energy efficiency.

1. Air Filtration Box: An air filtration box is a device used to filter and purify indoor air. It typically includes a filtration system that effectively removes particles, dust, pollen, bacteria, viruses, and other pollutants from the air. The air filtration box is usually installed in the ventilation system, where the air passes through the filter before being distributed into the indoor space, providing clean and healthy indoor air.
2. Air Heat Recovery Box: An air heat recovery box is a device used to recover and utilize the heat energy from indoor air. The heat energy in the indoor air is typically expelled outdoors through exhaust. The air heat recovery box employs a heat exchanger to transfer the expelled indoor air's heat to fresh outside air. This allows for the recovery of heat energy while expelling waste air, thereby improving the efficiency of air heating and reducing energy consumption.

Air filtration boxes and air heat recovery boxes are often used in combination to achieve comprehensive air treatment. The air filtration box ensures clean and purified indoor air, while the air heat recovery box provides energy recovery and energy-saving benefits. These devices play a vital role in providing comfortable and healthy indoor environments, particularly in terms of efficient energy utilization and environmental preservation.
