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. And that gets us to Seasonal SEER - but I won’t bug you with that.wood ac unit coverUpdated I think it is 3.51KW per RT [refrigeration ton], although that does not account for inefficiencies.1 RT = 12000 BTU/hour.ice air ac unitRefrigeration tons to kilowatts (kW) conversion calculatorwleWrittencentral ac units for sale in miami Marvair AVPA36ACA000M5-A2-100 - Wall Mount AC, ModPac, 3 Ton, 208-230/1, No Heat, Manual Damper, R410A ModPac™ II Air Conditioners Models AVPA12, 24, 30, 36, 42, 48 and 60 (1, 2, 2 1/2, 3, 3 1/2, 4 and 5 tons) The ModPac II is a cost-effective air conditioner used primarily for modular and relocatable buildings.

The unit is built in cooling capacities of 1, 2, 2 1/2, 3, 3 1/2, 4 and 5 tons. A factory installed disconnect is standard. Electric heat can be field or factory installed. Accessories include supply and return grilles and thermostats. The sloped top and built-in mounting flanges, both Marvair firsts, simplify installation. All ModPac II units are listed by ETL and tested to the Air Conditioning and Refrigeration Institute (ARI) Efficiency Standard 390. Our new M5 ModPac two ton air conditioner has been redesigned with additional features and greater efficiency. The unit has an electronic control board, high and low pressure switches and foil back insulation lining the return air path. In addition, the center-to-center mounting hole width was reduced by 3-3/4", allowing the unit to match the mounting holes on competitor's units. Ventilation Options "N" damper Manual damper capable of up to 15% outside air. Field adjustable, no pressure relief."B" damper Motorized, two position damper (open & closed) capable of 0 to 450 cfm of outside air and includes pressure relief.

A 24 volt actuator motor controls the damper from an external input, e.g., a CO2 sensor, an energy management system or manual switch.

Consumers should first become acquainted with the geothermal installation process to understand how the cost is derived. The short answer to how cost is calculated is as follows:

Indoor Portion + Underground Loop Field = Total System Cost The inside portion is composed of the price of the geothermal heat pump, its installation, and possible duct work modification. This is done by an HVAC contractor properly trained in geothermal. The Underground Loop Field involves drilling (or sometimes escavating) and materials. This is usually done by a well driller. The loop field is approximately 50% of the total cost, although many factors effect this generalization. For your particular situation the following variables are considered: The first factor that we'll take a look at is the size of the home or other building for which you'd like to install geothermal. Look at it like this - a 2000 sq. ft. home isn't going to require the same amount of heating and cooling as a 6000 sq. ft. church. The larger the area covered, the more heating and cooling it is going to demand. That said, a major variable of pricing is the insulation factor, which has a direct effect on how much

heating and cooling is needed. Do you live in a well insulated home or a cardboard box? Based on the size of the home, insulation, and climate the amount of heating and cooling needed is calculated, which in turn enables a contractor to calculate the size of the heat pump for the job. Needless to say, a larger heat pump is going to be a little pricier than one that's smaller in Next, the size of the loop field that's to be installed in the ground comes into play. The size of the system (3-ton, 4-ton, etc.) along with the climate in which your located will dictate the amount of pipe that needs to be inserted into the earth. A loop field contractor will usually charge a price per foot; therefore, the larger the system, the more pipe that needs to go into the ground, the more expensive the loop field becomes. The loop field cost can vary by region because of the availability of contractors, the ground conditions, and also the price of fuel. In most cases, this shouldn't be too large of a factor, as most existing ductwork requires little to no adjustment to be suitable for geothermal

That said, if you don't have existing ductwork then you'll have the full expense of installing it. However, it's important to consider that this is a cost for which you are going to be responsible for regardless of what type of heating and cooling you install. Ductwork is simply a necessity of almost all HVAC systems - not an exclusive monetary addition to your geothermal system pricing. These are some of the main players as far as the cost of your geothermal heating and cooling system goes. There are more minute components of pricing, of course, but we feel that these four (and all that they encompass) are the most important for consumers to grasp. Bottom line - Size of Home, Climate, & Labor dictate total system price. A quality contractor, with the right training and experience, is the key to a happy geothermal system customer. For this reason, it's important to never choose your contractor based solely on price. An inexperienced contractor can undersize your system, producing a lower quote.
