After the law on clean air act was passed in the year 1993, it was considered illegal to release refrigerant liquids into air without following regulations. After that period, repairing air conditioners became costly and required that many regulations are followed. This is also because new and complicated tools had to be used. The process had to be started by recovering refrigerant. Refrigerant recovery is done through evacuation of liquid from the system which is then stored safely.
Safety is one of the very important aspects of the entire process. The right types of tools should be used for the type of refrigerant. You will need to have safety goggles and gloves that are important in preventing frostbite. Also required will be charging hoses with valves at the ends. You have to check the condition of the hoses before getting to use them. In order to get the best outcome, you should use hoses that are short. The reason for this is to reduce impact on the environment.
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 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.
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.
