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 shorter the hose, the higher the pressure hence increasing the speed for the process. On the other hand, the longer the hose, the lower the pressure hence reduces the speed of the process. It is therefore advisable to use a shorter and a larger hose in order to ensure that the process is faster.
The dirt must also be kept away from the system. This is because the dirt may case some internal damage to the system. It is therefore necessary to put a filter at the inlet port to prevent the dirt from getting inside. Each time a recovery is conducted; there should be use of a new filter just to ensure that the interior is protected.
Interior of the system must also be kept clean. Any dirt and dust must not be allowed to get inside. This is because the dirt and other inferior objects are likely to destroy the interior of the refrigerant. A filter is normally used especially at the inlet port in order to achieve this objective. Use of new filter is always recommended each time the process is done.
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.
