looking for air conditioner for my new house, at least 6 aircon but something caught my eyes

http://www.hslg.com.my/products/index.php/...utdoor-1x4.html
it cost only $5k for 4 aircon..

multi-split system... not sure how it works but from the picture itself, we only need 1 outdoor motor instead 4 outdoor motor. it don't look messy. i seen b4 a house got 10 air con...it looks so messy..


anyone know how it works?
