What is Airco Saver

An innovative solution to reduce energy consumption
AircoSaver™


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 and 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 system, 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 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 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 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 just wastes energy.
Example:

Airco Saver installed only on One Lac split type A/C ranging from
capacity 1 Ton (12,000 BTU) to 5 Ton of refrigeration

 
Principal Load:
1TR(1.8 KW)X 20,000 = 36MW
2 TR(3KW)X25,000 = 75MW
4TR(5KW)X30,000 = 150MW
5TR(6KW)X25,000 = 150MW
Total = 411 Mega Watt
Airco Saver can save on an average  25% =102.75 MW
 
Consumption

If Airco Saver installed combination of residential, commercial & light industrial on one lac ton Air Conditioner running on an average 10 hrs/ day than total energy consumption would be 411X 5(compressor run-time)=2055MW/day

&
 
Airco Saver can potentially attain approximately 102.75X5=513.75 MW/day savings in total power consumption.

How it works

The Airco Saver 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 AircosaverTM switches the compressor off and avoids inefficient overcooling. 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, with averages of 20 to 30 percent, on compressors equipped, without compromising cooling comfort. Since the correct point to switch the compressor varies from unit to unit and changes with different weather conditions, the AircosaverTM is constantly adapting its settings to ensure efficient operation of your air conditioning system at all times.

The AircosaverTM is an easy and inexpensive way to make most air conditioners much more cost effective. An HVAC technician can install an AircosaverTM in less than 30 minutes.
