If the room receives a lot of sun, be sure to cover the windows with curtains or shades. air), Sensible Heat (BTU/hr) = 1.1 x CFM x Δt (std.

Hello Nancy, for a 1200+ sq ft condo, you would need at least 24,000 BTU portable air conditioner. The compressor-based refrigerant systems are air-cooled, meaning they use air to exchange heat, in the same way as a car radiator or typical household air conditioner does. To understand where they come from, let’s take a look at an AC’s operating cycle. Reverse cycle gets its name due to their ability to remove heat from inside a room to the outdoors, then reverse the process to bring the heat in from the outdoors and inside (when heating is required). 2) Try to point the air flow up. You would do best to contact local San Francisco HVAC experts (here’s a useful form for finding them). A gas, called a refrigerant, is introduced into the system to effect this exchange. Hi I Currently have the whynter arc 14s Unit you referenced above with two hoses. There is also a drain tank which needs emptying when it’s full and that is quite frequently.
