Ultraviolet germicidal lamp convenient to carry out direction control in air conditioning unit

Technical Field

The utility model relates to an ultraviolet germicidal lamp technical field who uses among the air conditioning unit, in particular to ultraviolet germicidal lamp convenient to carry out direction control in air conditioning unit.

Background

The fan coil is an ideal end product of a central air conditioner, and is widely applied to hotels, office buildings, hospitals, business and residential institutions and scientific research institutions. The fan cools or heats indoor air or outdoor mixed air through the surface air cooler and then sends the air into the room, so that the indoor temperature is lowered or raised, and the comfort requirement of people is met. The existing fan-coil unit mainly comprises a shell, a fan, a coil and the like in the shell. The cold (hot) medium water in the coil pipe is supplied from the machine room in a centralized way. It mainly depends on the forced action of fan to make the air pass through the cold water (hot water) coil pipe and then be cooled (heated) so as to keep the room temperature constant. Usually, the air is sent into the room after being processed by a fresh air unit so as to meet the requirement of fresh air volume of an air-conditioning room. Because fan coil system has easily to regulate and control, is convenient for install, advantage such as cost low, so its application is constantly expanding, and the product type is also constantly increasing.

With the improvement of living standard of people, the air conditioner is widely popularized to common families. The air quality requirement of people is promoted, dozens of common epidemic diseases and infectious diseases are transmitted by bacteria, such as tuberculosis, diphtheria, influenza, pollinosis, meningitis, asthma, legionnaire's disease and the like, and SARS and avian influenza can also pose great threat to human health by air transmission. World Health Organization (WHO) deems; the total number of bacteria in the air exceeds 700/m 3, and the risk of infectious diseases is obviously increased. There is a fear that the total number of bacteria in a building using a central air conditioner greatly exceeds this standard, and the total number of bacteria per cubic meter of air in some public places reaches more than one hundred thousand. In the building of the central air conditioner, people are surrounded by bacteria and viruses, and the theory of hearing and hearing is not really a hacker. In such polluted air environment, such as in the epidemic season, the health of the weak people, such as the old, the weak, the sick and the young, is seriously threatened. Singapore, Shanghai and many southern cities in China all belong to warm and humid climates, and the reproductive capacity of fungi is very strong.
