In recent years, with the improvement of people's requirements for the aesthetics of home decoration and the overall layout, household central air-conditioning products have begun to attract people's attention. When choosing, many small partners are hesitating, whether split air-conditioning products are more practical or household central air-conditioning products are more worth buying? Today, the author will briefly explain the difference between central air conditioning and split air conditioning. Interested friends might as well come and have a look. 1. Ordinary air conditioners: usually one-to-one, such as an outdoor unit corresponding to an indoor unit, as well as vertical air conditioners and window air conditioners. Generally suitable for small space environment. 2. Household central air conditioning, also known as household central air conditioning, is a miniaturized independent air conditioning system, which is similar to large central air conditioning in terms of refrigeration mode and basic structure. A host connects multiple end vents through air ducts or cold and hot water pipes to send cold and heating to different areas, so as to achieve the purpose of temperature regulation in multiple rooms, improving indoor air quality and preventing air conditioning diseases. What is the difference between ordinary household air conditioners and household central air conditioners in the purchase and use of consumers? 1、 System composition

ordinary household air conditioners are usually one by one: an outdoor unit corresponds to an indoor unit. And household central air-conditioning can be more than one: an outdoor unit can be connected to multiple indoor units. 2、 Use effect

a. compared with ordinary household air conditioners, the cooling speed is relatively slow, which generally takes more than 10 minutes, and the temperature fluctuates greatly (± 2 ℃), sometimes it is cold and hot; If the air conditioner without fresh air design is used for a long time, the indoor air quality will be poor

b, the cooling speed of the household central air conditioner is about twice that of the household machine, and the set temperature can be reached in 5-6 minutes. At the same time, the indoor air supply temperature difference is small, the air volume is large, the indoor humidity distribution is uniform, the temperature change is small (± 0.5 ℃), and there is no dead corner of the air conditioner; Moreover, the introduction of fresh air is convenient, the relative temperature is controlled between 40% and 70%, and the air is particularly comfortable and fresh. 3、 Aesthetics

a. The appearance of the indoor unit of the ordinary split household air conditioner is very similar, and the white rectangular shell is a little dull

b, domestic central air conditioning is different. The diversity of the use environment determines the diversity of indoor units of domestic central air conditioning. Users can choose different indoor units according to their own needs, such as cabinet machines, embedded machines, ceiling machines, air duct machines, duct hidden types, etc. 4、 Initial investment

A. based on the 120 ㎡ three bedroom and two living room, it is estimated that five air conditioners are required to load ordinary household air conditioners: one 3-piece cabinet in the living room, one 1.5-piece hook in the dining room, one 1.5-piece hook in the master bedroom, and one small one hook in the two small bedrooms. If the general fixed frequency air conditioner is used, the total price is about 20000 ~ 25000 yuan; The price of variable frequency air conditioner is about 25000 ~ 30000 yuan

b. the installation of household central air conditioning requires an initial investment of about 30000 yuan. If the digital machine and other relatively power-saving models are used, the price will be more expensive, but the average cost is not much different from that of household split energy-saving models. 5、 The total power consumption is

a. the power consumption of ordinary fixed frequency air conditioners is about 8kw, while the power saving frequency conversion model is about 6.5kw

b. In terms of household central air conditioning, the power consumption of digital models with relatively low power consumption is about 5.5kW. Therefore, for multi room houses, household central air conditioning generally saves about 30% power than household air conditioning, and the long-term use cost is less than that of ordinary split air conditioning. C. Using the traditional layout of split + cabinet machine to arrange the air conditioner, the initial investment is relatively cheap, the installation is also very convenient, and the warranty period is long. The initial investment of household central air conditioning is slightly higher than that of household split air conditioning, but at present, consumer groups who are able to buy multiple household computers are gradually changing their consumption concepts. After all, the gap between the purchase price of multiple household split air conditioners and household central air conditioning has become smaller and smaller, and consumers are more willing to pursue the beauty and comfort brought by central air conditioning. Purchase suggestions: for families with a small number of rooms (families with less than 1-4 sets installed), families with a small number of residents, or interior decoration is general (no ceiling), users who pursue less initial investment are advised to consider the installation layout of split machine + cabinet machine; Users with a large number of rooms or luxurious decoration and high requirements for comfort are advised to consider installing household central air conditioning. The more residential rooms and the more residents, the more cost-effective the product can be reflected by using household central air conditioning
