Indoor Unit

1. Heat exchanger:

There are cross-flow total heat exchangers, cross-flow plate heat exchangers or rotary heat exchangers to choose from to meet the different needs of customers.

2. PM2.5 solution
1) Efficiently remove haze
Equipped with a high-efficiency filter element, which can effectively remove PM2.5 particles carried in the air, ensuring that the outdoor air entering the indoor air is clean
