On the other hand, the installation requirements are very strict, and only the professional design and construction team can complete it. 3. Low cost of use: The traditional split machine is greatly affected by the indoor environmental temperature change. The fixed frequency air conditioner compressor starts and stops frequently and consumes a large amount of electricity. Moreover, the larger the room area, the more cost-effective to install the central air conditioner. Users who are new to central air conditioners will inevitably think that their prices are high, but after actually understanding their functions and effects, most mid- to high-end homes will give priority to home central air conditioners. 4, high comfort: household central air conditioner, each indoor unit has a air supply port and a return air outlet, the air circulation is more reasonable, the indoor temperature is more uniform, can maintain a constant temperature of ± 1 ° C, the human body feels more natural and comfortable.
