A ton refers to the amount of heat it takes to completely melt a ton of ice. Melting this amount of ice requires , Btu British thermal units. How fast the ice melts depends on how much heat it receives over time. For consistency, though, HVAC technicians began using 24 hours as their standard time period for air conditioners. The capacity of an air conditioner refers to the amount of heat it can remove. In addition, your contractor should follow Manual S.
Bend, Galveston, Sugar Lane or Brazoria areas. I thought not a single person would notice Chaucer in there. I also laughed out loud. Hmm… and just when I Hmm… and just when I thought you were going to demystify nominal capacity vs. AHRI capacity vs. David B. The discussion of whether to use Very Interesting! So in that sense, tons of ice was also a rate. But when automatic energy conversion systems like compressors entered the scene, engineers standardized on hourly rates, pretty much across the board.
Yo, Alison. Thank you very much, it was Thank you very much, it was very helpful…. Good explanation…although.. Good explanation…although…you can see more explanation about the rating of air conditioner in ton…here.. Zone 4 with a more moderate climate, starts from Virginia in the east to New Mexico, taking in Oregon and Washington State.
Consequently, zone 4 and the remaining areas of the US need an alternative heat source to provide suitable comfort levels. Each climate zone will have a different impact on the type of system and size of air conditioner to make your home comfortable.
As a general rule, a home in the hot, humid conditions of zone 1 or 2, might need to remove up to 30 BTU of heat for every square foot of floor area. Consider a single level house with a concrete slab floor of area, say square feet in zone 1. An air conditioner, based on this size area, in this climate zone, would require a capacity of 3. For this example, we would select a 4-ton unit because air conditioner capacities increase in steps of 0. Some of this energy will also be required to de-humidify the air in this zone to make the room more comfortable so a little extra capacity will help there.
If you live in any of the remaining zones, an additional heat source such as a heat pump or furnace and air handler, would be required to keep your family comfortable.
You can check detailed sizing calculation formula based on different zones here. While we have considered how air conditioners are rated and considerations of various climatic zones in the US, there are still many factors in your home to influence your decision regarding the best size system for you.
The first thing to consider is the floor area of the space to be cooled. This will have the most influence on the tonnage capacity of the unit required and easily calculated using the method detailed earlier.
