Written For the projects of our customers we use the following data for the design of the electrical installation:1. - 3.5 ton AC, environmentally friendly R410A, split system, with both condenser and air handler, central air conditioner system.2. - It is equal to 42000 BTU of capacity.3. - Power supply of 208-230/1/60.4.- Rated current of 22.1 A.5. - 16 SEER Efficiency.At acquisition and installation time we verify the data from the manufacturer of the AC and we make the changes if any.Written This will depend on the weather! If it is especially hot outside the AC will have to work harder to cool your space. It is impossible to give you an accurate answer to the question, but sometimes estimates can be made based off of typical load profiles in your area.Benjamin LyddaneWritten This question is under-specified. The energy use depends on the time during which the compressor and fan are working, and on the efficiency of the device and on the temperature difference between inside and outside.

The ton unit is a hold-over from the days when blocks of ice were delivered: in your case 3.5 tons a day. It is easy, but misleading, to work out the thermal energy stored in a block of ice when heated to room temperature ~ it is about 3.5 kW per ton of ice melted in a day.(12000BTU/hr in American units) But it is rather strange to realize that air-conditioning is one of those rare devices that give out more thermal energy than the electrical energy they use. This ratio called COP can amount to an efficiency of 300% to 1000% though air conditioners are not usually rated like this, but in a peculiar mixed unit ratio called EER, Energy Efficiency Rating which mixes BTU (output) divided by watt.hours (input) as the efficiency measure.If units are converted to a uniform system, EER is like COP (Coefficient of performance) using a scaling factor in this way:(EER) BTU/hr /watts = (COP) Watts out / watts input all times 0.293Until recently, efficiency as EER as low as 6 was permitted. Now AirCon units must be at least EER 6 and better is 12.Let’s suppose your 3.5 ton unit is brand new and moderately high efficiency.

That three and a half tons of ice represents 3.5 X 3.5kW thermal power divided by the efficiency multiplier now easily available (COP = 3.5) and we end up with 3.5kW as an estimate for the electrical power, consumed for as many hours as the outside temperature is too hot. harga ac portable mini sharpAnd that gets us to Seasonal SEER - but I won’t bug you with that.car air conditioning repair prestonUpdated I think it is 3.51KW per RT [refrigeration ton], although that does not account for inefficiencies.1 RT = 12000 BTU/hour.air handling unit condensate trapRefrigeration tons to kilowatts (kW) conversion calculatorwleWrittenThe ENERGY STAR Web page you are looking for cannot be found in this location.

But I don't know the difference between 4 and 5 ton. I live in Texas and it gets hot for three months out of the year but I will also have sprayed insulation in the attic with the possibility of radiant barrier also installed depending on the price of the barrier. Thxs in advance for your input. 26,349 posts, read 68,900,480 times 635 posts, read 2,279,224 times Originally Posted by eyewrist Not to belabor the point, but did someone spec the 4 ton based on an actual cooling load/heat loss calculation? I really do see some old timers say things like, "well, you have 2200sqft and all my years tell me you need 4 ton", but don't take into account the new tech, insulation, etc.

I'd get a couple/three calculations done and hopefully they'll all be close. If not, I'd ask questions why. I'd also suggest doing some individual research into pricing and rebates for higher SEER units. When we installed our 15ish SEER unit a couple years back, it was not significantly more expensive than the 13 SEER option. Any pro worth their salt will be happy to do heat loss/cooling load calc for free or a small fee as part of the estimating process. If they refuse, I'd think about sending them on their way. While the SEER 16 may be more expensive than a SEER 14 for example, depending on you electricity rates, the breakeven point might not be that long. In Huntsville, our electricity is cheap, like $0.09/kwhr. Back where I lived in Los Angeles it was between $0.15 and $0.25 so a high SEER AC would be a good idea in LA.
