| Load Calculations - Each room is
calculated with the amount of wall, ceiling, floor and glass.
From this, we determine the amount of sensible heat we need to
remove from each room to provide desired temperature.
Air Flow Calculations - An area overlooked by many A/C
Contractors today. Information from the room by room load
calculations is taken and applied to the piece of equipment
chosen. With this calculation, we can determine the correct
amount of air from the equipment that needs to be delivered to
each of the rooms.
When air conditioners operate to cool our homes, they are not
adding cool air, they are removing heat. Below are
explanations of some of the components involved in cooling of
your home or office.
Condensing unit - The condensing unit is responsible
for discharging heat. This is the unit that is usually seen
beside a house or building or on a roof. The unit consists of a
coil system, a fan, a weather-resistant compressor and a
control logic.
Air Handler - The air handler blows air through a cold
coil (which cools the air ) and routes the air throughout the
building or house using a series of ducts.
Seer - This stands for Seasonal Energy Efficiency
Ratio. The SEER is a measure of the air conditioner's
efficiency when cooling. The higher the SEER rating, the more
efficient the air conditioner. SEER Ratings range from 13.00
to 19.50, while some older models may be as low as 6.00.
Upgrading to an A/C with a higher SEER rating can lower your
annual cooling bill.
BTU - This stands for British Thermal Units. Generally
speaking, a BTU is the amount of heat required to raise the
temperature of one pound of water, 1 degree Fahrenheit (0.56
degrees Celsius). Specifically, 1 BTU equals 1,055 joules. In
heating and cooling terms, 1 "ton" equals 12,000 BTU. |
