Qian Jia ventilation and constant pressure machine eliminates room odor
Release time:
2021-02-24
Many people have experienced this: after traveling, going out, or being away from home for a while, if windows are left unopened, a large amount of dust can accumulate, creating an unsafe environment. Upon returning, one often finds the indoor air to be murky and foul-smelling, taking a long time of airing the space to gradually eliminate the odor. This is especially frustrating during hazy or windy weather. What causes this? Both southern and northern buildings have centralized ventilation and drainage systems that can create negative pressure within the indoor environment.
Many people have had this experience: after traveling, going out, or being away from home for a period of time, they cannot open the windows, otherwise there will be a lot of dust and it will be unsafe. Upon returning, they find that the indoor air is stale and has a very unpleasant odor. It takes a long time to air out the room by opening windows and doors, and even then the odor might not fully dissipate. Or if it happens to be a hazy or windy day, the mood is completely ruined. What is the cause of this? Whether in the south or the north, buildings have centralized ventilation and drainage systems, which can cause negative pressure within the room.
What is negative pressure? It is the phenomenon where the indoor air pressure is lower than the standard outdoor atmospheric pressure. Due to the principle of atmospheric pressure equilibrium, low indoor air pressure will cause other airflows to supplement the indoor air. The main pathway is through the drainage pipes, while other pathways are either closed or have higher wind resistance. The long-term accumulation of unpleasant odors will have a permeation effect, causing some clothes, bedding, and textiles to have odors, which pose health risks and severely affect the quality of life.
The Qianjia ventilation and pressure control machine can easily solve the above problems. The fully automatic intelligent computer can measure the basic negative pressure in the room with an accuracy of one ten-thousandth (i.e., one atmospheric pressure is approximately 10030pa). A pressure difference of one Pascal is sufficient to start the ventilation and pressure control system and filter the incoming air. In winter, it can also heat and disinfect the air. (Refer to the instruction manual for specific operating procedures).
