There are some tips which are necessary to take note of while conducting refrigerant recovery. It is important to understand the system properly before conducting the refrigerant recovery. It is therefore necessary to identify the type and the quantity of the refrigerant as the first thing to do. Identifying the system will also enable you to know whether to use extra filtration before conducting the recovery. Identifying the quantity and the type also helps in the planning for the requirements needed for the storage and the actual recovery.
The first step entails removing the liquid and any vapor out first. The liquid and the vapor are removed from the bottom access ports where the liquid normally accumulate in. If the liquid is not removed, then the recovery process will be slower as compared to when they are removed.
The speed of the process depends on the size and the length of the hose and the valve. For instance, larger valve reduced the friction while conducting the process thereby speeding up the process. On the other hand, thinner hoses will increase the friction thereby lowering the speed.
The size, shape and length of the hoses used in the system are also of great consideration in ensuring that the process is smooth and faster. The hose must be as wide as possible. This will ensure that the friction is reduced or eliminated. If the friction is high, the speed of the process will reduce. The length of the hose must also be kept as short as possible.
It is important to protect the interior of the system from any dirt and dust. A filter is therefore used to make sure that the interior is protected. It is normally placed at the port to filter in what is getting into the interior of the refrigerator. It is advisable that each time the process is done, a new filter is used. This is also to make sure that the interior is fully protected.
It is also necessary to highlight some of the recovery methods. There are three methods frequently used. The first one is known as push pull method. The second one is known as liquid method while the third one is known as vapor method.
Push pull method entails the use of pressure differential in removing the liquid from the system. It is commonly used in refrigerators with receiver tanks. The method does not effectively work in smaller systems which is not having the receiver tank. The system must not also be having a reversing valve or even a heat pump. This is because the reversing valve will make the liquid to form into solid.
Liquid method on the other side is preferred for using in systems which do not have oil compressors. It is also preferred where the system is capable to recover the liquid. On the other hand, vapor method entails using an additional hose. The additional hose is placed in between the machine for recovery and the storage tank. The vapor is then passed through the added hose then it is being cooled after passing through the compressor. Therefore it is important to note that the methods are suitable to be used in different systems. The above tips are essential in carrying out refrigerant recovery.
