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 procedure is a slower one but us the one that is used most. It involves transfer of refrigerant in its vapor state. The two methods, liquid and vapor, are the same. The difference comes in because the refrigerants in the two processes are transferred in different states. This in essence also means that settings on the unit are also different.
The push pull technique removes liquid refrigerants fast but is a two step process. After removal of all the liquid in step one, there must be a change of hose connections for the vapor to be recovered. In essence, the push pull method is only used when there are more than 10 pounds of the refrigerant. For the liquid recovery technique, refrigerants are transferred when still in their liquid state.
When it comes to vapor recovery, there is condensing of vapor into liquid at the recovery unit before it gets transferred into a cylinder. Before the process is started, the system being services must be switched off and all its valves closed. The other procedures can then be carried out.
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.
