Whether you are sleeping in the comfort of air-conditioned bed room or working in your office with air-conditioning temperature set at the best comfort, you are at the least aware of electrical energy supplying into the air-conditioning system.
Most people know that newly installed air-conditioners give the silent cooling comfort, trusting the efficiency of the system.
The refrigeration cycles of the refrigerant running from the compressor to heat dissipative coil, and across the expansion valve followed by the fan coil cooling units, is running at its most efficient way.
Little do occupants of home and buildings realize the thief of electricity that would come hiding in the air-conditioners.
The thief is none other than the corrosion of the heat-exchanging coil of the condenser units.
The outdoor condenser/air cooled chiller unit is highly susceptible to corrosion.. With corrosion comes a slow but inevitable loss of heat exchange efficiency which ultimately wastes electricity and costs money.
How does this happen ?
The condenser coil/fins are corroded by the environment, leading the impedance of heat dissipation of heat from the compressed refrigerant. The refrigerant that is to achieve full molecular compactness in full liquid state assisted by heat dissipation through the condenser coil, is now impeded.
The resultant state of refrigerant is sub-optimal compactness of molecule of the refrigerant, could now be semi-liquid-semi-gaseous state. At such state, the efficiency of heat absorption through the expansion, valve become less efficient. The compressor is required to work harder (more frequent activation) to keep the room space at set cooling temperature.
Probably less than 1% of the occupants realize when the electricity bill is building up over time.
On top of that once the corrosion has started, the lost efficiency is difficult to recover. If corrosion is significant the coil will obviously be replaced at a huge cost.
It is thus more critical than it seems that the corrosion should be prevented right from the moment the air-conditioning system is installed, or be restored as soon as possible.
