Window AC / September 20, 2018 / Marphisa Babin.
Window air conditioners come in various sizes and it is important to choose the one that best fits the size of your room and needs of the user. The first thing to consider is to the rooms size. Using an climate control unit calculator or using the Energy Star chart for choosing a properly sized cooling appliance. For the average 150-250 square foot room youll need a climate control unit that has a capacity of 6000 BTUs. If you have rooms that flow into one another with archways or open doorways youll need to include the square footage of the adjoining room when calculating the capacity necessary to cool the area. Outside of square footage it is important to consider the climate of the room you wish to cool with an air conditioner.
The Advantages of window air conditioning units: They are cheap. Compact. Sometimes provide partial ventilation. No installation required. Easy transportation from place to place. Suitable for apartments summer cottages and offices. Window air conditioner can be easily installed in a shop on wheels. Another important advantage is long lifetime: window air conditioners seldom get to a service center mostly after many years of usage (the simpler the system - the more reliable it is). The disadvantages: High noise level. They block a part of the window stealing the daylight. The window frame must be altered.
Side panels fill the gaps on the sides. These are also very thin so most of the sleeve is uncovered and outside. This allows for placement of ventilation louvers on the sides and top allowing free movement of air. This is the primary difference between the two types. The wide availability of louver space allows the unit to move a lot of air and this means window units can be quite powerful up to 3 tons or 36000 BTU. So window A/Cs can be effective for very large rooms. In contrast a wall air conditioner sleeve is designed for a hole through the wall. Walls vary substantially in thickness.
This will help you determine the amount of BTU s necessary to cool your room adequately. For example an 8000 BTU unit will cool a room up to about 350 square feet. Another thing to consider when buying a window unit is any special features that come with the unit. In particular most window units include louvers that let you direct airflow programmable timers so that you can set the unit to turn off or on when you wish and energy efficient features like multiple fan speeds. Many units also come standard with a remote control so that you can adjust the temperature from across the room.
