How is central air conditioning sized?
The proper way to size a central air conditioning system is to measure and compute, on a room by room basis, the rate at which warm air enters the home. This calculation, which is stated in BTU’s of cooling load, is known as a heat gain calculation. Central air conditioning systems are rated in terms of “tons” of cooling capacity. One ton equals 12,000 BTU’s per hour. What is the meaning of the S.E.E.R. rating of an air conditioner? S.E.E.R. stands for Seasonal Energy Efficiency Ratio. This rating is determined by dividing the total amount of cooling (measured in BTU’s of heat removed) by the total energy used (measured in watts) over an entire heating season. The higher the S.E.E.R. rating, the more efficient the air conditioning unit and the lower the operating costs. At what temperature should I set my central air conditioner? One of the most important functions of central air conditioning is to remove excess humidity from the home. Since this process takes time, it is important tha
