Seer energy savings calculator for air conditioners electricity water analogy


It then compares this data with that of a higher efficiency air conditioner to determine how much an AC with that SEER rating could save you annually hp gas online in cooling costs. The air conditioner energy calculator also displays your projected cumulative savings over a five year, ten year and a 15 year period. In most cases, the potential savings are pretty amazing! What is SEER?

According to the AHRI standard, SEER is calculated by first determining the total amount of heat removed from a home during a typical year’s cooling season. This number is expressed gas city indiana zip code in Btu’s ( British thermal units 1). The Btu’s are then divided by the total electrical energy the air conditioner or heat pump uses during that same cooling season. This is expressed in watt-hours (Wh). So, SEER = Btu / Wh.

SEER is also calculated based on indoor and outdoor temperature. Naturally, the outdoor temperature during a typical cooling season is not constant. It varies based on weather and climate. The SEER equation makes an effort to account for this by mimicking a typical cooling season, using a range of possible outdoor temperatures, 65°F to 104°F to be exact. These temperatures are divided gas constant mmhg into 8 sets or “bins” of 5° increments. Each bin’s average temperature is assigned a fraction of the total annual cooling hours. The indoor temperature, on the other hand, is based on a set 80° with a 50% relative humidity. (This applies to the temperature of the return air, not the supply air.)

In addition to a SEER rating, heat pumps also carry an HSPF rating gas monkey bar and grill, related to the efficiency of its heating capabilities. (In case you don’t know, the only difference between a heat pump and an air conditioner is that a heat pump is able to run in both directions. It simple terms, it can either cool your home by transferring warm air from the inside of your home to the outside, or it can heat your home by transferring warm air from the outside, inside.) Thus, HSPF stands for Heating Seasonal Performance Factor.

EER, standing for Energy Efficiency Ratio, is also similar to SEER and is calculated in a nearly identical manner (Btu/Wh). The main difference is that EER doesn’t take into account fluctuations in the average outdoor temperature geothermal electricity how it works during the cooling season. Instead, its basis is a constant outdoor temperature of 95° F. On the other hand, SEER calculations, as discussed gas giants above, are made based on outdoor temperatures ranging from 65°F to 104°F. Both SEER and EER equations use the same set indoor return air temperature. What are the Current Air Conditioner Efficiency Standards?

Ever wondered why you can’t find an air conditioner with a lower than 13 or 14 SEER rating anymore? That’s because there are national energy efficiency standards that enforce a minimum SEER rating on all air conditioners and heat pumps sold and installed. The latest update to these standards went into effect on January 1, 2015. This map shows the current minimum SEER, HSPF and EER ratings by region:

All this electricity units calculator in pakistan being said, it is still possible to own an air conditioner with less than the minimum SEER rating. In fact, if your air conditioner dates from before the first efficiency standards went into effect in the 1990’s, it may carry as low as a 6 SEER rating. (If this describes your AC, then you probably already noticed that the “current air conditioner” slider on our energy savings calculator doesn’t go below 9 SEER electricity bill cost per unit. Hint, hint.) How Do I Find My Air Conditioner’s SEER Rating? There may be a yellow Energy Guide label like this one adhered to the body of your condensing unit.

What do we mean by “match”? Most manufacturers make their air handlers compatible only with certain condensers for optimal performance. HVAC contractors are generally required to install air conditioners in these matched sets, but this unfortunately does not always happen. If your unit is mismatched, it’s unlikely that z gas cd juarez it will achieve the SEER efficiency promised on its label. Rats! What is AC Tonnage?

We know what you might be thinking – and no, tonnage does not refer to the physical weight of your air conditioner. Although tonnage is often referred to as the AC’s “size”, this really means its cooling capacity. More specifically, it tells how much heat the unit is able to remove from your house in one hour. For instance, a one ton air conditioner can remove 12,000 Btu’s of heat from your house in one hour electricity 2pm’s time. A two ton air conditioner can remove 24,000 Btu’s, and so on.

So, what size of air conditioner do you need to effectively cool your home? That depends electricity kwh calculator on various factors such as your home’s square footage, the number of occupants and the number of windows. Here’s a chart containing some of the typical AC sizes by square footage. If your home is larger than these examples, you may need multiple air conditioners working simultaneously. Anything over a 5-ton air conditioner is considered a commercial size and is not available for residential use.
