Overview[ edit ] Billiards balls hitting each other are a classic example applicable within the science of collision detection.

Some refrigerant leaks will stand out at you, sometimes you can see traces of oil around the compressor, indicating a refrigerant leak, or sometimes you can smell the gas and pin point it from there. But what about those tiny leaks that only seem to grow over the years.

You could have purchased a new system 2 years ago, and it may have only lost a pound of refrigerant. That refrigerant leak could be getting bigger and bigger as the years go by, but you just keep paying to have refrigerant added to the system. Now the customer, or YOU if you are the customer, have to fork over a heck of a lot more money to get it replaced.

These methods should only be performed by those that work in the HVAC field.

Heating and air conditioning is a very technical field and every situation is different, thus this article should be used as information purposes only per our sites disclaimer. I would first look around the compressor for any signs of oil.

Then fill the system up with about lbs of dry nitrogen. You should be able to hear the leak hissing when examining all of the HVAC components.

There are two types that I like to use and they are the heated diode type and the infrared type leak detector. It gets great reviews from some of the professionals over at Hvac-Talk.

The advantage of this type of technology is that the sensors will last about 10 years. They trigger on refrigerant concentration, so a sweeping motion must be used with this type of leak detector.

The only disadvantages I have with infrared leak detectors is that they are more expensive. But then again you get what you pay for. Works great on sniffing out R and A refrigerant leaks. I have heard good things about the D-Tek leak detector though, which has been upgraded to detect A accurately.

If I were to buy another refrigerant detector it would be the D-Tek just because most the guys I work with use it and love it. HVAC Dye Test There are leaks that can occur in evaporator and condensing coils that just will not trigger on some leak detectors.

Either that or they just take too long to find. Dye kits will consist of dye cartridges, a UV flashlight and glasses. You basically inject the dye into the system while it is running, and let the dye cycle for a couple of days.

Return with your UV flashlight and glasses and the dye will light up where the refrigerant leak is present. One of the most efficient ways to pinpoint small refrigeration leaks. The drawbacks to this is it can be pretty messy.

Wear gloves, and make sure you have the proper stuff to clean up the mess you will make, which is usually included in the dye kits.Ponerology, the science of evil, rooted in secret investigations, objectively studies how evil deceptively spreads destruction, waste, neglect & suffering, taking over systems & how to oppose abuse, heal victims & develop healthy, sustainable systems immune to evil.
