Is it harmful to install central air conditioning in home? Analysis of advantages and disadvantages

When it comes to central air conditioning, many people will think that it is most common in major supermarkets or office buildings. However, with the improvement of people's living standards, central air conditioning has also become the choice of many families, entering thousands of households. So what are the advantages and disadvantages of central air conditioning? Let's have a look.

What are the advantages and disadvantages of central air conditioning

1. Price: as the products of central air conditioning are engineering products and involve many links, the price is much higher (the marketing expenses, design, positioning, construction and after-sales of dealers will be paid by consumers). The central air conditioner of the same house is about twice as expensive as the total of the same brand variable frequency split units (for example, Gree's three room and one hall split unit is about 17000, and the central air conditioner is about 30000). However, considering that the central air-conditioning only occupies a space outside the air-conditioner, and the internal unit does not occupy the cabinet space in the ceiling, so whether it is cost-effective depends on the situation of each household.

2. On the central air-conditioning, we should use the central air-conditioning according to the normal cost of electricity. Because the external unit of central air conditioning is larger (the area of heat exchange fins is larger), when 10% - 60% of the internal units work at the same time, the energy efficiency ratio will be much higher than that of the whole machine (equivalent to paying a share of electricity to the compressor, which carries more heat, because the external unit has large heat dissipation fins and stronger heat dissipation capacity). This is the natural advantage of central air conditioning, because most families are turned on in this way It is very rare that all internal machines are opened together. There is also a case to be taken into account, the general air conditioning just started more power consumption, because the energy consumption to turn Freon into low temperature. When the split machine is shut down, there are still a lot of low-temperature Freon (in fact, the liquid Freon after releasing a lot of heat) in the outer machine, and it will be turned into normal temperature after a few hours. This part is very wasteful. Central air conditioning because an external unit is working, so as long as there are other rooms continue to use, there is no waste of this part.

3. Service life: the decoration cycle is generally about 15 years. There is little difference between central air conditioning and split machine.

4. Collocation and decoration: there are many links that need to be connected between central air conditioning and decoration, such as the influence of internal unit on the layout and height of ceiling, the incorporation of condensate water and downpipe, the power line of internal and external units, the reservation of air outlet and access port, the position of control panel and switch, etc. Therefore, it must be a professional HVAC company and reliable decoration company, as well as each link with the professional master.

5. Worry free: the more complex things, the lower the reliability, but there is no way. This is the performance of human progress, we can not stop it. The various problems of central air conditioning in front of us are the manifestation of immature market in the early stage. Many companies are not professional and are still in the exploratory stage. They will gradually get better. This has been done well in developed areas. The central air conditioner and the split machine need to clean the filter screen regularly. This is normal maintenance. Other problems (such as fluorine leakage and water leakage) are installation accidents.

Generally speaking, central air conditioning stands outside the province, good matching of interior decoration, energy saving and other links have advantages. The disadvantages are high price and many problems. If you want to do air conditioning in a professional way, you have to find a professional company. If the budget is limited, you can only do the split machine. It is recommended to install air duct fan in the living room, which does not occupy the space and is not expensive.
