The invention discloses an
indoor air conditioning
system and method. The
system comprises an air
inlet channel and an air outlet channel which respectively communicate with the indoor and outdoor spaces, wherein a filter screen, a deduster, an
ultraviolet lamp, a fan, an
HEPA (high efficiency particulate air) filter and an
ion generator are installed in the air
inlet channel; and a fan is installed in the air outlet channel. The method comprises the following steps: adding
inorganic ions into outdoor clean air introduced from the air
inlet channel, and sending the air with the
inorganic ions to all corners in the indoor space; decomposing organic pollutants, peculiar smell,
bacteria, mold and other pollutants discharged by an indoor
pollution source; and discharging the
indoor air through the air outlet channel, and decomposing the indoor organic pollutants. The
system is provided with two wind paths, and is capable of introducing outdoor fresh clean air and discharging indoor dirty air to improve the indoor environment and temperature, thereby thoroughly solving the problems of cleanliness and freshness of the
indoor air. Furthermore, the system has the advantages of simple structure and low cost, and is easy to implement.
