Window AC / September 12, 2018 / Lundy Brochu
Window air conditioners came to the market as a solution for people who couldnt afford or did not want central air conditioning. Because central air conditioning can be quite expensive and because many people live in small apartments central air is not for everyone. This led to the advent of window air conditioners. Window air conditioners have a hot coil and a chilled coil along with two fans. The fans blow air over these coils and they in turn suck away the heat and humidity from the room into the outside area providing clean cool air. The capacity of an air conditioner is measured in BTUs. So the size of the air conditioner plays a vital role in determining its cooling capacity.
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.
The ductwork for the distribution of the air is also all ready in place. The ductwork may need some modification to make it work well for air conditioning but the major part of it should be adequate. To use the existing furnace and ductwork a coil will need to be installed at the furnace. An outdoor condenser unit will be installed outside and copper tubing will be used to connect the coil to the outdoor unit. Some electrical wiring will need to be done to power the outdoor unit. Low voltage wiring will be needed to hook the thermostat the furnace and the outdoor unit together so that they can talk to each other. Basically the thermostat will just tell the furnace to run the blower on high speed and the outdoor condenser to start up.
