Is it more cost-effective to install central air conditioning in a relatively small house?

Outdoor unit cost, indoor pipeline cost, indoor fan coil unit cost. But there is a problem. Outdoor units can account for about 80% of the total cost of central air conditioning. That is to say, if a central air conditioner is installed at home with a total price of 20,000 won, then the cost of this outdoor unit alone can be close to 15000 won. The remaining fan coil units and pipes are not expensive. If my house is small, there are fewer indoor machines and fewer indoor pipes. But from the original assembly point of view, its cost will not be reduced much. Because the outdoor unit is free, we can compare it. Personally, if the 80-square-meter house and the 120-square-meter house are equipped with central air conditioning, the total cost of the two houses will not be much different. Therefore, from the perspective of installation cost, the small area of the house is considered completely useless.

The indoor fan coil unit blows cold and heat into the room only through the indoor fan. So its most important power consumption part is the outdoor unit. Generally speaking, the power of the outdoor unit can reach about 3000 watts, but the power of the indoor unit can be lower than 100 watts or higher than 100 watts. When the central air conditioner is in use, whether it is a small house or a spacious house, the central air conditioner uses the most electricity during the start-up process. So the power consumption is almost the same when starting, and it is very low when reaching the set temperature. The house area is small, but the electricity bill will not be saved much at this time. Therefore, from the perspective of the operating cost of central air conditioning, small-area houses will not be much less than large-area houses.

The indoor unit of household central air conditioner can be hidden in the ceiling to avoid occupying indoor space like a cabinet, which brings more freedom to furniture layout, complements the style of home decoration and improves the effect and grade of home decoration. The fuselage and pipes of traditional common cabinets and wall frames are exposed, which does not occupy space and is not beautiful. Is there any benefit in small-sized central air conditioning? Central air conditioning is very comfortable. The comfort of central air conditioning is also very high. Each indoor unit of the central air conditioner has air outlets and ventilation holes, which makes the air circulation more reasonable, the indoor temperature more uniform and the human body feel more natural and comfortable. Connecting the air duct can provide air for the bathroom. Traditional household wall frames and cabinets are prone to air dead angles, and the indoor temperature difference is obvious, which is easy to suffer from "air conditioning disease". The outdoor unit of the central air conditioner is a mainframe. Because there are many outdoor units, it affects the appearance of the building and easily leads to accidents. The refrigerant connecting pipe of the traditional molecular sieve machine is exposed to avoid hanging in the indoor gap.

It is reported that the market share of central air conditioning has increased year by year, from 5% two years ago to 30% now. In the past two years, many air-conditioning brands have designed practical low-cost small-sized central air conditioners. At present, many families under 80 square meters are also choosing home central air conditioning. In fact, in developed countries such as Singapore, Japan and South Korea, many families use two or three central air conditioners every day. The installation of central air conditioning is more economical than the general split air conditioning in terms of beauty, comfort and operating cost. I believe that in the near future, central air conditioning will become the mainstream of the market.
