Fan coil units should create an indoor air quality natural environment suitable for physical comfort. Because the natural environment of indoor air quality has a very important effect on body comfort, the natural environment of indoor air quality stipulated by body comfort has become the most important work of central air conditioning. If the indoor air temperature is 24 neon 11Y and the relative humidity is 55% and 15%, the air conditioning work should not only maintain the temperature base of 24 flares and 55% humidity base, but also ensure the temperature precision of 11Y and * 5% humidity precision of fan coil unit (that is, the fluctuation range of allowable temperature and humidity), as well as higher freshness and cleanliness.
The natural environment of indoor air quality required by manufacturing process should be considered. Some technological processes of production and manufacture stipulate extremely high natural environment of temperature and environmental humidity. Temperature and environmental humidity standards not only immediately endanger the normal development of production and manufacturing process, but also endanger the production and quality of commodities. Such as textile production, precision instrument production and pharmaceutical production technology, etc.
Clean up harmful substances in the room and concentrate the heat and moisture released. CO2 in comfortable central air-conditioned rooms and bad taste in bathroom. Harmful substances such as flavor and harmful substances caused by assembling workshop of central air-conditioned processing technology, and parts of its position of releasing heat and moisture, fan-coil units need passage air-conditioning and exhaust facilities to eliminate, so as to obtain a good room. Internal air environment.
