Aircosaver… What is it?
What is an Aircosaver?The Aircosaver is an award winning Electronic Control Unit, compliant to UL and CE regulations, which adds state-of-the art intelligence to air conditioning systems. Air conditioning is one of the largest energy consumers in the residential and industrial sector. Thousands of air conditioners put high demands on electric grids already strained to capacity. On a smaller scale, air conditioning probably accounts for a significant part of most energy bills and electric costs are rising rapidly! Many existing air conditioners use old and quite inefficient technology. Although improved technology has become available in more expensive systems (e.g. inverter technology), the payback time of these systems is still very long.
Instead of investing a lot of money into an expensive new system, there is an easy and affordable way to improve the energy efficiency of your air conditioning unit - Upgrade it with an AircoSaver.
Why Use An Aircosaver?
When switched on, typical air conditioning systems operate continuously until the room thermostat senses the desired temperature and turns the system off. As the room warms up, the thermostat switches the air conditioner back on and the cycle repeats. Air conditioning systems are usually dimensioned to cope with the extreme cooling demands of the few hottest days of the year (plus a safety margin). However, in most operational conditions, this maximum output is not required and the system is over sized. So running the system continuously until the room thermostat switches it off means that the system operates with excess capacity most of the time.
A typical cooling cycle with excess capacity looks like this:
- When the cycle starts, the compressor pushes cooling energy into the heat exchanger which acts as an energy storage. At this stage, the system works with high efficiency because compressors operate most efficiently when fully loaded.
- In normal weather conditions, the energy storage is soon fully “charged up”. From this point onwards, the compressor provides more cooling energy than the heat exchanger can take up (thermodynamic saturation).
- Running the compressor beyond this stage does not increase the cooling effect any more, it’s just a waste of energy!
Typical Aircosaver installations include: homes, offices, schools, universities, restaurants, hotels, shops, supermarkets, banks, etc.
How Does The Aircosaver Work?
The Aircosaver compensates for the shortcomings of typical air conditioning systems by adding intelligence. Its sensor-driven software algorithms are designed to detect thermodynamic saturation and to optimize the compressor accordingly. When overcapacity is detected, the Aircosaver switches the compressor off and avoids inefficient over cooling. Your unit switches into “saver mode”. The fan keeps running and your system makes maximum use of the stored cooling energy in the heat exchanger. Once the stored energy is used up, the compressor can work efficiently again and is switched back on. The set room temperature is reached without the inefficient parts of the cooling cycle. This results in significant energy savings, 20-30%, without compromising cooling comfort. Since the correct point to switch the compressor varies from unit to unit and changes with different weather conditions, the Aircosaver is constantly adapting its settings to ensure efficient operation of your air conditioning system at all times.
The Aircosaver is an easy and inexpensive way to make most air conditioners much more cost effective. Any electrician or HVAC technician can install an Aircosaver in less than 30 minutes. The total cost for both the Aircosaver and installation will have a return on investment of less than 18 months!
The product will literally pay for itself in only a few months.”
Companies who have Benefited – Commercial References
Below are companies that have benefited from the award winning Aircosaver Electronic Control Unit
- EPA (US Environmental Protection Agency) certified Aircosaver
Multi-location (48 store) test with DOMINOS PIZZA (2009) – The controller immediate energy reductions are realized in excess of twenty one percent (21%) for an annual savings of $156,863. The return investment of the project is under one (1) year.
- Project Green Light certified Aircosaver AT&T install on 5/30/08 for Building E4509, Plantation, Florida.
The controller energy reduction Cost per/Month savings of $151.90. That was a 38.91% reduction in cooling costs. The return investment for this install was eleven (11) months.
- State of Florida Pompano Correctional Facility showed an energy savings of twenty two percent (22%).
- Energy Audit for Indian Institute of Technology, Bombay Campus.
Energy Savings achieved by installation of Aircosaver for a 1.5 ton AC. Thus savings of 35-40% was seen when the energy saver was fitted. With a simple pay back period of eight (8) months.
- HSBC Bank Test Evaluation Trial of the Aircosaver Unit was completed and verified by HSBC Engineers and, as a result, 24.4% energy savings was recorded by data logger, HSBC is embarking on a procurement program from Aircosaver to install the system on all air conditioning units
Is the Bloom Box the answer?
Fuel cell technology has been around for sometime now and most companies offering this technology have a difficult time turning a profit. Is the Bloom Box so different that a revolution is now upon us? I will leave that up to you to decide. I am all for energy saving technology and I certainly hope the Bloom Box lives up to all the positive hype I have seen. With my electric bill hitting over $500 this month alone I could use a good energy saving device besides the aircosaver i already have installed. In the interest of fair play I have attached an article that takes a more skeptical view of the Bloom Box. Happy reading.
