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 lesser the friction, the faster the speed of the process. It is also advisable to use a short horse. If the horse is long, the pressure will decrease hence also making the process to take long. The Schraeder valves should also be removed first before starting the process.
A shorter hose will ensure that there is no reduction in the pressure hence the process will be conducted faster. On the other hand, if a longer hose is used, there will be a reduction in the pressure hence the process will be slower. A wider and a shorter hose therefore is recommended if one is interested in ensuring that the process is faster.
It is also worth noting the various recovery methods which one may use in conducting the recovery. These methods include the vapor method, the liquid method and the push pull method. These methods are used depending on the type and the size of the system.
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.
