The fan coil unit concealed in the ceiling should be horizontally or ceiling mounted

Since it is "concealed in the ceiling", of course, you should choose the horizontal concealed fan coil unit, which is cheap and can also match the decorative effect well.

The ceiling-mounted type belongs to the surface-mounted wind tray, and the price is higher, and the reasonable collocation of the wind tray and decoration should be considered.

The fan coil unit installed in the ceiling should be horizontal.

The main control parameters of the horizontal concealed fan coil unit are rated air volume, outlet static pressure, input power, rated cooling capacity, rated heat supply, noise, water resistance, etc. For the fan coil unit of the double-pipe water system (suitable for the air-conditioning system that only converts heating or cooling according to the season or the air-conditioning area), only one set of coils is configured, and the heating and cooling models are used in winter and summer. For the fan coil unit of the four-pipe water system (suitable for the air conditioning system with frequent conversion of heating and cooling), the combined model of heating and cooling coil should be configured.

It is recommended to go to NetEase to place drawings and look at relevant books, they can't say it, only to experience it yourself.
