When the outside temperature begins to rise, many are those who seek the cool comfort of indoor air conditioning. To some, an air conditioner is purely a luxury, but to others it's simply a necessity. This guide will discuss the important relevant issues when you are considering getting an air conditioner for your home.
Technically speaking, a split air conditioner unit splits the hot side from the cold side of the system. Instead of having only one mechanism managing both side at the same time in the same room, such as a window unit, the split system comes with one unit located outside your home (compressor) and one wall mounted unit inside (diffuser), where the name “Dual split air conditioner”.
BTU (British Thermal Units) is an international thermal unit measurement system enabling us to know, among other things, the cooling capacity of an air conditioner. The higher the BTU number is, the more cooling power the air conditioner has.
An 800 square feet room will require a 12,000 BTU unit (depending on home insulation).
SEER (Seasonal Energy Efficiency Rating) or EER (Energy Efficiency Rating) is the energy performance rate. The SEER or EER factor indicates the efficiency level of the air conditioner to convert the electrical energy into cold air. So, the higher the SEER values are, the cheaper the unit will be in energy consumption.
- The advertised models are also offered in thermopump version (Heat pump)
- There is no difference, apparently speaking, between an air conditioner and a thermopump. The difference is inside the unit.
This means you can use it to heat your home or office up to 10º Celsius. You can also use it for heating with these units in a range of colder temperatures by installing an extreme cold operation kit.
An Air Crystal thermopump can make you save more than 30 % of your heating costs in electricity. In addition, the air heated and blown by the diffuser is more comfortable than electric baseboards. The heat produced by the thermopump is as warm as the one of a traditional fireplace.
A KFR-35GW/GX1b (Heating/12500 BTU) consumes 1090 watt/hour (1.1 kilowatt/hour).
The average price for 1 kWh is 0.06 cents.
Therefore, the KFR-35GW/GX1b model consumes 1.1 kWh x 0.06 cent = 7 ¢ per hour.
Considering that the compressor is controlled by the room thermostat, it means that even if the unit is "ON" all day, your forecasted daily electricity consumption will be less than $1/day, either on air conditioning or heating mode.
The calculation is simple:
The compressor does not run all day, because it stops and restarts based on the thermostat demand. It runs about 14 hours every 24 hours. At a cost of 0.07 cents an hour, therefore 7 ¢ x 14 hr. = 98 ¢ per day.
Heating or air conditioning with a thermopump is therefore quite economic!
