Abstract: This split-type room air conditioner absorbs the advantages of current split air conditioner and room air conditioner models. Our innovation makes it possible for a split air conditioner to be used in apartments and condominiums. We improved both air conditioner unit disadvantages. For example, a split air conditioner indoor unit is very flexible so that you can hang it up in the right place to get a good cooling balance, but the outdoor unit has a big size and is not feasible as a typical room air conditioner. And room air conditioners have a good size to fit pre-constructed apertures and window places, but only can be put in limited places (low level places), thus creating a cooling imbalance in the room and making too much noise. We did technological innovations to combine the advantages of both type air conditioners. We reduced the outdoor unit size thickness by ?. We have enhanced the cooling speed and reduced the noise level (db) of our room unit.

Abstract: Currently, there are no products available which allow a user to solely remove microbial and bacterial growth inside a blocked HVAC condensate drain line using compressed air without cutting into or disassembling the drain line. Our valve is an in-line condensate drain line valve that can be installed easily, quickly and economically, either during new construction or onto existing HVAC systems. The HVAC user can remove microbial and bacterial growths without cutting into or disassembling the drain line by injecting compressed air through the valve. The design of our valve allows the user to perform safe and routine maintenance to the HVAC drainage system without having to resort to expensive and repetitive service call repairs over the lifetime of the HVAC system. The valve is further designed to prevent undesirable reverse airflows into the HVAC system and home or building, caused by a dry trap in the condensate drain.
