Electronic Compressor Control Unit which adds state- of- the
art intelligence to air cooled air conditioning systems |
Air conditioning is one of the largest energy consumers in the residential an industrial sector. Thousands of air conditioners put high demands on the electricity networks. On a smaller scale, air conditioning probably accounts for a significant part of your energy bill. 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 systems, there is an easy and affordable way to improve the energy efficiency of your unit-Upgrade it with an Aircosaver™

| Shortcomings of typical AC systems |
| |
| When switched on, typical air conditioning systems operate continuously until the room thermostat sense 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 oversized . 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 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 wastes of energy! |
