Since the passing of the clean air act in the year 1993, release of refrigerant liquids into air is considered illegal. Since then, the job of air conditioning repair has become more complex because of the introduction of expensive, new tools and equipment for the job. Any serious AC repair or service will need to start with recovery of the refrigerant. Refrigerant recovery involves evacuating the liquid from the system and its safe storage.
One of the first considerations is safety of the procedure. The right equipment have to be used for the procedure. Safety will be key, which is why goggles and gloves are needed. They will prevent frostbites. You will also require charging hoses with valve ends. The condition of the hoses must be checked prior to using them. Short hoses are preferred for the best outcomes. They also reduce environmental impact.
For the recovery process, there are three basic methods, that is, vapor, liquid and push-pull. For the liquid recovery process, it is possible to transfer the refrigerant when it is in the liquid state. It is a method that is good for transfer of refrigerants from one container to another. This is the fastest of the three procedures. However, it cannot be used for all HVAC systems. There are cases that will require the vapor process.
The vapor process is slower than the liquid one but is the most commonly used method. The refrigerants in this case are transferred while in vapor state. The liquid and vapor methods are similar with the only difference being that the refrigerants are recovered in different states. There are also differences in settings on the unit.
The push pull methodology will remove liquid refrigerants very fast but is done in two stages. In step one, there is removing of all the liquids. After that, the hose connections are changed so that vapor is recovered. Essentially, the push pull method will be used when there are 10 pounds or more of refrigerant. In the liquid recovery method, transfer of refrigerants is done when they are in liquid state.
In the case of vapor recovery, there is condensation of the vapor within the recovery unit after which it is transferred into some cylinder. This process is carried out when the systems has been switched off. All the valves should also be closed. After that, the procedure can be completed safely.
For the transfer of large quantities of refrigerants, the push pull process is used. The recovery unit will pull vapor from the cylinder and will produce high pressure discharge gas. This will push liquid from the HVAC system and back into the cylinder. This is a procedure that is very effective. However, it will need a lot of equipment and can be difficult to carry out.
Whereas some of the procedures are able to be done individually, most people prefer to let them be done by experts. This will have several benefits. For once, there are environmental regulations that must be followed that only experts can ensure are adhered to. Safety is also key and professionals will ensure there are no risks.
