Ducted vs. central air conditioning, which is better?

Duct and central air conditioning difference.

Speaking of the concept first: ducted machine, full name is the ducted central air conditioning, in fact, it is also a split machine, and hanging cabinet machine belongs to the split machine. For example, a brand duct machine model KFR-50**, k on behalf of the air conditioner, f on behalf of the split. so, the duct machine belongs to the improved version of the traditional air conditioning, is the manufacturer in order to fill the small air conditioning and central air-conditioning products launched in the middle of the market. Its temperature control calculation logic is similar to that of small air conditioners. (Thus, in the long run, its energy efficiency ratio and quietness are worse than that of a central air conditioner.) At the same time, the term duct machine is also a form of central air conditioning internal machine. The form of central air conditioner internal unit is divided into horizontal concealed duct unit, single-sided embedded indoor unit, double-sided embedded indoor unit, four-sided embedded indoor unit, etc.. So the old iron is easy to confuse these two concepts. (Mobile phone typing is really tired, to be not praise, I give you no end) concept clear it (knock on the blackboard), to the subject at the same time to open three to four for the normal use of working conditions to do the following comparisons: 1, the indoor air supply (decoration effect) there is no difference between the two, there is no difference in the ceiling impact. There is no question of who takes up more of the ceiling. Outdoor air duct machine is more, will damage the facade, open more than one, the external noise source more. 2. indoor machine silence, the same brand duct machine (inverter) and the central air conditioning indoor air conditioning machine is almost the same, the central air conditioning is slightly better. 3. open three to four, energy-saving, the central air conditioning is high. Open a, ducted machine (inverter) more energy efficient. There is nothing else, right? By the way, there is the initial investment.4. Central air conditioning is higher than ducted units. Combined with their own budget reasonable choice.

There is a saying in the air conditioning industry: three parts equipment, seven parts installation. Equipment basically each brand is relatively homogenized, installation is the test of a centralized system follow-up is an important factor in the stability. Traditional rubber insulation produced by nitrile rubber (tire) foam, the follow-up will continue to release formaldehyde in the ceiling, extremely detrimental to the health of the family. This is the source of the unpleasant odor blowing out of the air vents when the air conditioner is turned on during the change of season. Conditions allow, central air conditioning users are advised to choose Wise Home PE insulation, Japanese production process, zero formaldehyde, without any odor, very environmentally friendly, in order to the health of the family, spend a little more money, I think it is very necessary. In addition, Wise Home PE insulation whole root is very long, unlike the traditional rubber plastic 2 meters a, traditional rubber plastic joints are many, there is a hidden point of water leakage.
