Can the beam dividing the upper and lower floors of the air-conditioning unit be removed?

If you are sure that you only need to install one air conditioner, or if the other air conditioner above is fixed with brackets on the wall, you can smash the prefabricated panel, but you must ensure that the wall behind the machine can withstand the air conditioner. weight.

Another thing to note is that if the middle partition is smashed, it may cause an airflow short circuit when two sets of air conditioners are turned on at the same time, that is, one of the air conditioners (especially the lower set) The hot air blown out is sucked into another set of air conditioners, causing poor heat dissipation of the other set of air conditioners, resulting in poor performance or overheating protection.

During heating in winter, if the upper set of air conditioners is not equipped with an outdoor unit for drainage, once the weather is cold and the upper set of outdoor units defrosts, its defrost water will flow directly to the lower set of air conditioners. , causing the air conditioner below to become severely frosted and even unable to defrost, resulting in extremely poor performance.
