Guidelines Of The Refrigerant Recovery Process
by Mattie Knight
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. <A href="http://www.chillerservicesrefrigerants.com">Refrigerant recovery</A> 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 process of recovery, there are three main methods that are used. They are vapor, push-pull and liquid. The liquid process makes it possible to transfer the refrigerant in its liquid form. It is used in transferring the liquid from a container to another. It is the fastest among the three procedures but unfortunately cannot be used for all types of HVAC systems. Some systems will need 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 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 vapor recovery, the vapor is condensed into liquid using the recovery unit before being finally being transferred to some cylinder. Before starting this process, it should be ensured that the system being serviced is off, with all valves closed. The remaining procedures should be followed step by step.
When it comes to transfer of large refrigerant amounts, you will use the push pull method. There is the recovery unit that pulls vapor from the recovery cylinder and produces discharge gas at high pressure. The gas pushes liquid from the system then back to the cylinder. It is one effective procedure. Nevertheless, it requires lots of equipment and may be complicated, making it difficult to implement.
While some of the procedures may be done individually, most people will prefer to use professionals. This is partly because there are environmental regulations that must be followed. Experts will deliver the best services.
