About

Aircond Saver  

Air conditioning has a huge potential for efficiency improvements

Air conditioning is one of the largest energy consumers in the residential and industrial sector.

Thousands of air conditioners put high demands on our 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 and most of this technology is not suitable as

an easy and economical aftermarket fit to existing systems.

In the light of today's energy problems, global warming and since older and not so advanced

aircon systems will be in use for many more years in large numbers, we have analysed various

existing energy saving techniques for air conditioning systems and reviewed plenty of earlier

research. The conclusion was that detecting the system's efficiency and switching the

compressor accordingly is probably the only effective, pragmatic and economical measure to

achieve a better energy efficiency. There is no "free lunch" with any retrofit, but these savings

come at no or only very small decreases in cooling comfort.

Upgrade your unit

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 existing unit:

About the Aircond Saver – Short comings of typical AC systems

A typical cooling cycle

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.

Most air conditioning systems are oversized for the majority of operating

conditions

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's just a waste of energy!

How Does It Work?

About the Aircond Saver, How does the Aircond Saver improve

energy efficiency?

The Aircond Saver compensates the shortcomings of typical AC units and

adds intelligence to your AC system

The Aircond Saver 's sensor-driven software algorithms are designed to detect

thermodynamic saturation and to optimize the compressor accordingly. When overcapacity is

detected, the Aircond Saver 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 without compromising cooling comfort.

Since the correct point to switch the compressor varies from unit to unit and changes with

different weather conditions, the Aircond Saver is constantly monitoring the cooling status of

your aircon unit and adapting its settings to ensure efficient operation of your air conditioning

system at all times.

Protecting your unit against short cycling

Cycling the compressor too frequently in too short time intervals may harm the compressor

and must be avoided. For this reason, the Aircond Saver features a built-in anti short

cycling protection.

Besides the continuous anti short cycling protection, the Aircond Saver also adds a delay

upon power-on to your unit. This valuable feature protects your aircond unit against damages

from short power outages like they are common in many developing countries.

Theory

The energy consumption of air-conditioner is mainly electricity. Aircond Saver traces the working load of compressor by microcomputer chip (MCU), optimize the operation curve by alto, and instruct the temperature console of air conditioner to modify the average operation currency and time intelligently and eliminate the inference by temperature compensation.

The Aircond Saver adopt the technologies of the real-time automatic temperature compensation technology, the temperature interval control technology and the thermal transmit theory, combine the value setting controlling and process controlling, optimize the control process by humanoid control theory. MCU compensate the temperature with the real time date and the thermal conversion formula to achieve the effect of high-efficiency, optimization and management. It purify the electricity of supplier by filer the harmonic inference, peak voltage and surge currency. It is proved that the system can promote the economy and reliability of air conditioner.
