AIR CONDITIONING AND HEATING SYSTEM CONTINUED
In-Line Refrigerant Dryer
The in-line dryer (Figure 7, Item 4) receives the high temperature high pressure liquid refrigerant from the
condenser coil. The refrigerant passes through the desiccant (Figure 7, Item 3). The moisture is removed in the
desiccant (Figure 7, Item 3). The refrigerant continues to the orifice tube assembly (Figure 7, Item 2), which is the
location where the high temperature high pressure liquid is changed into a liquid vapor mixture that is low
temperature low pressure. After exiting the in-line dryer, the refrigerant continues to the evaporator coil. The in-line
dryer connects to the refrigerant circuit with a quick disconnect fitting (Figure 7, Item 1).
