　　 The reason for this situation is that the two do have a lot in common: the air outlets are all concealed installations at the top of the room. Its core functions are all related to indoor air. . . So what is the difference between the two? This article starts from the core function to interpret this problem for you.

　　The difference in core functions: temperature regulation VS fresh air exchange

　　Central air conditioning: indoor temperature regulation

　　 In the final analysis, central air-conditioning is also a type of air-conditioning. The core function is to adjust the indoor temperature. The concept corresponds to the "split air-conditioning" of one-for-one household.

　　The essence of central air-conditioning is still the word "air-conditioning". The essence of central air-conditioning is still the word "air-conditioning".

　　 Central air-conditioning has several obvious advantages: high comfort, good energy-saving effect, and strong integrity. The central air conditioner mostly adopts the "one-to-many" design of one outdoor unit + multiple indoor units, which can easily achieve the temperature balance of the rooms in the whole house, and the product is strong, the installation is concealed and beautiful, and the energy-saving effect is better; for multiple rooms For large-sized users, central air-conditioning is the best choice for adjusting indoor temperature.

The return air vent of the central air conditioner cannot be exchanged with indoor air. The return air vent of the central air conditioner cannot be exchanged with indoor air.

　　 However, the function of central air conditioning is limited to the adjustment of indoor temperature. Although it also has a return air port, it cannot be exchanged with indoor air. To achieve the effect of indoor and outdoor air circulation without opening windows, the intervention of a fresh air system is required.

　　 Fresh air system: indoor and outdoor air replacement

The core function of the fresh air system is the replacement and convection of indoor and outdoor air. When we turn on the air conditioner, we often need to close the doors and windows. In the enclosed space, problems such as the accumulation of carbon dioxide concentration and insufficient oxygen concentration are likely to occur. The fresh air system solves this problem. The best choice.

In 2000, the European Union unified the residential ventilation standards, and the fresh air system has become an inevitable choice for buildings. Compared with natural ventilation, the fresh air system has a larger air exchange rate, the air exchange has both intake and exhaust, the airflow organization is scientific, reasonable and orderly, and the air exchange effect is better.

　　 In addition, most of the fresh air systems currently on the market have air purification functions. While realizing indoor and outdoor air circulation, they can also intercept and adsorb pollutants in the outdoor air, effectively improving indoor air quality, killing two birds with one stone.

Through the distinction between the core functions of the two, we can see that although central air conditioning and fresh air systems solve indoor air related problems, their core use requirements are completely different. For users, both functions are crucial. Important and irreplaceable.

　　Three common questions to confuse product selection and installation

　　 Regarding the choice and installation of the two, I will help you with three common questions and answers:

　　①Is my home suitable for installing central air-conditioning?

　　Answer: Central air conditioning is not suitable for all families. For users with ultra-small units (<40㎡) or low floor heights (<2.6m), I do not recommend installing central air conditioners, because a 3-hp air conditioner cabinet is enough to meet the heating and cooling needs of the whole house, and installing central air conditioners will also appear The space is too depressing.

　　 In addition, the central air conditioner adopts embedded installation. Generally, the design, planning and construction are carried out simultaneously with the decoration. Drilling, drilling, and laying of pipelines are all necessary steps. If your home has just been decorated, there is no need to install central air conditioners.

　　②The central air conditioner is installed in the home. Is it necessary to install a fresh air system?

　　 Answer: It is necessary. The central air conditioner only solves the indoor temperature adjustment and does not have the function of ventilation; while the fresh air system can ensure the air quality in the confined space and provide users with clean and fresh air at any time. Its purification module can also provide a certain air purification effect. Only by complementing each other can the indoor environment be comfortable and healthy.

　　③What kind of fresh air system is suitable for my home?

　　Answer: The fresh air system is divided into two categories: ducted fresh air and ductless fresh air, and its applicable people also have distinct characteristics.

Like the central air conditioner, the ducted fresh air also needs to be designed and planned before decoration. The installation is carried out simultaneously with the house decoration. After the installation is completed, the air duct adopts a hidden design that will not damage the interior decoration style; this type of fresh air system is suitable Users who plan to renovate or are undergoing renovation.

The installation of a ductless fresh air system is relatively simple. You only need to open a ventilation hole on the wall and then fix the machine on the wall. The installation is convenient and the amount of work is small. For users who cannot install the ducted fresh air system during decoration Said it is a good compensation plan.

　　 At this point, this article has come to an end. I hope this article can help you correctly distinguish the concepts of central air conditioning and fresh air systems, and provide certain guidance and suggestions for your product selection and installation.
