Household central air conditioner is an air conditioner in which a host computer controls different rooms to achieve indoor air conditioning by means of air ducts or cold and hot water pipes connecting multiple terminals. Adopting the air duct air supply method, one host can control multiple different rooms and introduce fresh air, which can effectively improve the indoor air quality and prevent the occurrence of air-conditioning diseases.

The most prominent feature of household central air conditioners is to produce a comfortable living environment. Secondly, from the aesthetic point of view and the best use of space, the use of household central air conditioners makes interior decoration more flexible and easier to achieve various decorative effects, even if you don’t like the original Decorate and re-decorate, the original central air-conditioning system is slightly changed to be in harmony with the new decoration. Therefore, household central air-conditioning is called a one-step, never-behind choice.

2. Limitations:

1. Layout: design and installation must be combined with decoration to achieve good comfort and decorative effects;

3. Classification of main components:

(1) According to the medium used to bear the indoor heat and humidity load, it can be divided into:

1. All air system

2. Full water system

3. Air-water system
