The main topic of my bachelor thesis was the design of a mobile air conditioning unit for a household. My aim was an innovative and interesting solution of the shape of its design and an usage of modern and extraordinary technologies in this category. I was dealing with an issue of the impact of air conditioners on human health; of the usage of different types of air conditioners, of their qualities, of their advantages and disadvantages. Also, I was focusing on shape of mobile air conditioners, on their function in living spaces. The mobile air conditioning unit Aircan is a portable device for an airtreatment in smaller rooms. With its qualities, it is more-less a classic mobile air conditioner with standard functions, but its form is definitely atypical. The shape basis is a cylinder; a dominant material of its envelope is brushed aluminium and black plastic. To a lesser extent, a stainless steel is used for a completion of an aesthetic interaction of the materials. I fulfilled my goal thanks to the inspiration in minimalism and science-fiction movies. The shape and the overall character is definitely extraordinary and different to other devices in the category of air conditioners. The atmospheric lighting is also unique and it has in addition an informative character. The control of the device is widely automatized; a mobile phone application is used instead of a remote control. Nearly a total absence of control elements on the body of the air conditioner relates to the philosophy of the minimalism; the objective is to achieve simple pure shape-lines. My air conditioner design sets a different view on ordinary elements of air conditioning devices.
