All You Need To Know Concerning Refrigerant Recovery

By Anita Ortega


The strict rules and guidelines on how to work with coolants were established after government learned the disaster that comes with improper handling of the same. If refrigerant recovery is done per the provided guidelines, the rate of ozone layer depletion will go down significantly. This will in turn reduce the levels of ultra violet rays that reach the surface of planet earth. Refrigerants are also associated with global warming. Tapping such gases will help check the greenhouse effect.

The regulations requiring mandatory recovery of coolants be done have been in place for more than a decade now. Any one who does not abide to these guidelines is subject to prosecution. It is required that all the machines applied in evacuation of gases be first approved by environmental agency. One will be safe if he obtains and reads all the federal as well as state laws governing the procedure.

One of the most common substances applied in cooling, Freon, was first introduced to the cooling industry at around 1930. Since the compound was found to be not poisonous and easy to manufacture, its introduction was deemed as a big achieving in the air conditioning sector. It was only for scientists to establish later that the compound had adverse effects to environment and that people were to pay a price for the comfort they had enjoyed in the past years. Research indicated that the compound contributed to degradation of ozone layer once it was released into the atmosphere.

The risks associated with ultraviolet radiations are what caused the environmental division to come up with strict measures on how refrigerants should be handled. Examples of known effects of UV waves are increased cases of cancer of skin, defects in the body immune system, and more cases of eye cataracts, vegetation damage and endangering of sea life.

The stability of Freon, which is one of the characteristics that made it earn great endorsement in cooling industry, is what makes it harmful to the ozone blanket. The chlorofluorocarbons are able to travel high into the atmosphere where they can remain for more than hundred years. Sunlight energy forces the compound to release chlorine atoms which reacts with the protective blanket to release free oxygen and chlorine monoxide.

The horses of equipment applied in recovering refrigerant must have shutoff valves. The connection of the horses to the refrigeration appliance service fittings should be done while the valves are closed. The coolant is recovered up to a point where the refrigerator control indicated a vacuum.

To ensure that air is not sacked, the air conditioning appliance should be tested to ascertain it is charged with a refrigerant. The vacuum value should not be less than 102 millimeters. Mild heat can be applied to melt ice where it is detected.

The required clothing should be provided to the technician who is executing the recovery process. Regulations demand that the tank used in storing refrigerant that has been recycled to be one that can be disposed. All the power cables should be inspected to find out whether they are in good condition prior to the evacuation exercise.
