Two Stage Air Conditioning System Advantages
What is the advantage of a two stage air conditioning system compared to a a single stage air conditioning system?
Benefits of a Two Stage Air Conditioning System Verses a Single Stage AC Unit:
A two stage air conditioning system has many more comfort features, one of the best features is the on-demand dehumidification feature. The on-demand dehumidification feature will allow you to feel more comfortable at a higher temperature set point with a lower percentage of humidity in the air. Comfort aside, when moisture levels are high, there’s a higher potential for mold and other pollutant problems that could potentially lead to health issues.
How does it work?
The air handler fans speed ramps down into a lower speed utilizing a variable speed motor, when it ramps down to a lower speed it starts pulling more humidity out of the home.
Here is an Example
When you set your thermostat to 76° on the single stage system the air-conditioner will continue to run at 100% capacity in order to bring it down to 76°. However, on a 2 stage system with the humidity control feature you can set your thermostat to 78° and then set the humidity at 45%. Once the air-conditioner reaches 78° The two stage air conditioning unit will drop down into first stage and the fan speed will drop down as well, this allows the air conditioning unit to begin the dehumidification process and then starts to pull the humidity level down until it reaches 45% humidity in the home. Once it reaches 45% humidity the AC unit will shut down and it will feel like 76° even though the temperature is actually 78° in the home. This is because the humidity is only at 45%. This will save you money on your electric bill because your air conditioner does not have to operate at 100% capacity all the time of time in order to bring your home temperature down 76°
A two stage air conditioning system works 2 stages on the compressor mode, it starts up at 66% drawing less amperage upon start up and this is where you consume most of your energy costs. If the heat load in the home calls for more cooling 15 seconds later the 2nd stage kicks in the 100% capacity mode. Example, if you have a 4 ton air-conditioner with a 2 stage system it will start up as if it were a 2.5 ton drawing the amperage of a 2.5 ton system and then 15 seconds later it will go to 100% (only if the heat load in the home calls for 100% capacity) which will be a full 4 ton capacity however on a single stage system it will always start up at 100% capacity and draw the amperage that a 4 ton compressor will need and that 100% capacity is what winds up costing you more money on your energy bill. Dual stage air conditioners also tend to last longer because they are not running at full capacity all the time.
Two stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.
Longer cooling cycles also translate to quieter, more efficient operation, enhanced humidity control, substantial savings on your annual energy costs and extended lifespan of your cooling and heating system. Compared to a single-stage unit, a dual stage air conditioner or heat pump can remove twice as much moisture from the air. This is important because when moisture levels are high, there’s a higher potential for mold and other pollutant problems.
