Abstract

The invention provides a purification fan coil. A filter screen is arranged at the position of an air exchange opening, and the filter screen can kill harmful bacteria and viruses in air of the air exchange opening and conduct oxidative decomposition on harmful peculiar smell in the air and is high in air purification efficiency. Photocatalyst layers are arranged on cooling sheets, continuous adsorption purification and photocatalysis purification can be conducted on the circulating air, and the beneficial effects that the air purification effect is obvious and the purification efficiency is high are achieved. In addition, by arranging the coil, temperature of air blown out of an air outlet can be kept uniform, and the temperature transfer efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration terminals, and in particular relates to a purification fan coil unit. Background technique [0002] Fan coil unit is the terminal device of central air conditioning system and small central air conditioning system. It is suitable for large and medium-sized and scattered places that require tranquility, such as hotels, shopping malls, office buildings, hospitals, laboratories, computer rooms, offices, etc. It is a hybrid device of centralized and local air conditioners. Its working principle is that the air in the room is continuously recirculated in the unit, so that the air is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant. Usually, the fresh air is sent into the room after being processed by the fresh air unit, so as to meet the needs of the fresh air volume of the air-conditioned room. The fan coil air con...
