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.
Among the most useful aspects of the process is safety. There should be the use of proper equipment for the type of liquid in question. One of the first things that will be required is a pair of safety goggles and gloves that will help to prevent frostbite. There will also be the need for charging hoses that have valve ends. You should always check the condition of the hoses before they are used. For the best results, the shortest hoses should be used. This will reduce impact on the environment.
There are three different techniques that can be used. These are the liquid, vapor and push pull methods. In the liquid technique, the refrigerant is able to be transferred in its liquid state. It is the technique that is suitable for transfer of refrigerants from a container to another one. It is the fastest procedure among the three. Unfortunately, it cannot be used for all types of HVAC systems.
The vapor process is a bit slow compared to the liquid one but remains the most commonly used technique. Refrigerants will be transferred while in their vapor state. The two methods are almost similar, with the biggest difference being the state of the refrigerant. The settings of the unit will also be different.
The other procedure, the push pull one, is very fast but is done in two steps. There will be removal of all the liquid in the first process, after which there is change of hose connection so that vapor is recovered. It is the best method to use when there are more than 10 pounds of refrigerant. The other two techniques would not be ideal in this case.
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.
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.
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.
