With the continuous expansion of people's home area and the improvement of the quality of life, home central air conditioners have been favored by many families. It inherits the system advantages of large commercial central air conditioners, and is more flexible and compact. But in fact, because of the ignorance of home central air-conditioning, many people are faced with a variety of products on the market, often unable to start, in the confusion and misunderstanding of the understanding and purchase, then we will come to understand the central Knowledge about air conditioning.

The decoration should reserve the necessary installation position for the central air conditioner, and match with the home decoration style to achieve the desired decoration effect and experience.

1, determine the specifications of the outside machine
Before purchasing, you must first understand the specific indoor area of ​​the air conditioner, and select the cooling capacity of the air conditioner outside the actual use. In general, the actual use of cold is often not the sum of the total room cooling, but lower than the latter, about only need to reach 60% -70% of the latter.
2, choose the internal machine and the tuyere
The indoor unit and the tuyere are determined according to the actual required cooling capacity. Each room or hall only needs one indoor unit or tuyere. If the living room is large or rectangular, you can add an indoor unit or a tuyere to each. 12 square meters need one or so.
3, arrange air conditioning layout
The location of the host should be well ventilated and easy to maintain. At the same time, it should be avoided to be adjacent to the bedroom and the study room; the indoor unit should be equipped with interior decoration and hidden in the ceiling; and the air outlet layout should be arranged according to the reasonable structure of the room. At the same time optimize the return air mode.
Understand data measurement performance metrics
Refrigeration (heat), energy efficiency, and noise are the three key indicators for measuring the strengths and weaknesses of air conditioners. They are also one of the criteria for determining the strength of air conditioning. When purchasing, measure whether these hard data meet the standards.
1, cooling (heat) amount
The heat that the air conditioner removes from the sealed space per unit time during the cooling (heat) operation. Legal measurement unit W (Watts). The national standard stipulates that the actual cooling capacity of air conditioners should not be less than 95% of the rated cooling capacity.
2, air conditioning energy efficiency ratio
The energy efficiency ratio, also known as the coefficient of performance, refers to the ratio of the cooling capacity to the cooling power during the cooling operation of the air conditioner, in units of W/W. According to national standards, the energy efficiency ratio of 2500W air conditioners is 2.65; the energy efficiency ratio of 2500W to 4500W air conditioners is 2.70.
3, air conditioning noise
Noise is the noise generated when the air conditioner is running, and is mainly generated by the internal evaporator and the external condenser. The noise generated during the operation of the air conditioner is mainly generated by the internal evaporator and the external condenser. The national air conditioner indoor unit with a cooling capacity below 2000W shall not exceed 45 decibels, the outdoor unit shall be no more than 55 decibels, the 2500W to 4500W split air conditioner indoor unit noise shall not exceed 48 decibels, and the outdoor unit shall be no more than 58 decibels.
Comprehensive consideration of after-sales
In addition to the product itself, when choosing a central air conditioner for home use, we must consider various factors such as cost performance, brand and installation and maintenance. After all, we must carefully drive the ship for thousands of years to strive for maximum perfect use of air conditioners.
1, considering the price
Users should subscribe to a cost-effective home central air conditioner according to the actual room size, usage habits and economic ability. It is necessary to shop around, but not blindly pursue cheap, some products may have a slightly higher price and installation cost, but better quality. Long life, low power consumption, and lower overall cost.
2, pay attention to installation and maintenance
While understanding the amount of home central air conditioning, it is necessary to comprehensively consider the installation experience, construction team, user reputation and after-sales, etc. If the service provider reduces the price in order to reduce costs, cut corners and not follow the standard design, it will bring a lot of unnecessary trouble.
3, choose a strong brand
Large brands will carry out a series of quality control such as raw material inspection and production process control in accordance with national standards during production, and the quality is trustworthy. In addition, the comprehensive strength of the business, only have more professional technical support, the project quality is more secure, and the follow-up after-sales service will be more perfect.
