Household air-conditioning ventilation how useless?
Household air conditioning in the trachea has eight points In 30 cubic meters per hour Wind speed I don't know!
Air-conditioning maintenance, I do this thing no practical value, mainly is to make the room air outside the room air to communicate to purify air, this air conditioning to buy expensive but it's not a practical effect, home air conditioning refrigeration and heating, is only required to other functions just lick the head, there is no use a lot of use. What ghost transaired function, on the other hand, is a blind, home air conditioning is a closed cycle, only indoor air through the evaporator (indoor machine) outside air into not to, even in the affected refrigeration capacity
There is no practical value, usually on a regular basis to open doors and Windows by ventilation.
Useful. But the actual application of effect is not very good. At present in domestic wall-mounted air-conditioner with a small number of manufacturers, there are a few models of the function, wall-mounted air-conditioner installation, on the wall a suitable to the size of the hole in the wall, wearing a hose expansion to achieve a certain amount of the introduction of outdoor air, which is the introduction of outdoor air. But due to the structure of wall of household air conditioning is restricted, its own set of air filtration level is not high, introducing the air directly from outside is not very good filtering processing after air conditioning evaporator into the room, it will bring some other types of problems. Another wall-mounted air-conditioner indoor machine evaporator evaporation heat transfer capacity is not large, directly after the introduction of a certain amount of outdoor air, the introduction of new wind often get proper temperature degree, can't satisfy the family's need for temperature control. Based on the above points, which has the function of ventilation air conditioning of the actual effect is not ideal.
