Without a seat, you have to separate yourself from the head office with a seat. When sealing the balcony, leave a corner at the corner, isolated from the outside world, and finally the outdoor air conditioner has a "shelter". With the glass partition, the sound of the machine will be much smaller. If you feel that the external machine is an eyesore, you can add a curtain and pull it down instantly to become invisible.
The balcony is set against the wall, and sometimes it will be made into a cabinet, bar or laundry cabinet. The external machine can not only store things, but also be placed obliquely in this position. When the sliding door is pulled, air convection will occur, and the heat dissipation will be faster.
