Answer :
Final answer:
A filter-drier on the high side of the capillary tube system should be installed just before the capillary tube to effectively protect against moisture and debris. Its placement ensures the refrigerant is filtered and dehydrated before undergoing the pressure drop and cooling process in the capillary tube, enhancing the system's efficiency and reliability.
Explanation:
A filter-drier on the high side of the capillary tube system should be installed at the point where it can protect the capillary tube from both moisture and debris effectively. The primary function of a filter-drier in a refrigeration or air conditioning system is to absorb system contaminants, such as water, and to filter out particles that could clog the capillary tube.
Installing it on the high side is critical because this location ensures that the refrigerant is cleaned and dehydrated before it passes through the capillary tube. This placement helps in maintaining the efficiency of the system while preventing any potential blockages or damage that could arise from moisture or debris within the refrigerant.
It is significant to have the filter-drier positioned correctly to ensure the long-term reliability and efficiency of the HVAC system. The exact placement can vary depending on the specific design of the system, but typically it is installed just before the capillary tube on the high-pressure side of the system. This strategic location allows it to carry out its filtration function just before the refrigerant undergoes the pressure drop and cooling process in the capillary tube, thereby maximizing the protection against contaminants.
