Refrigerant Piping

Table 4: Recommended Horizontal or Downflow Discharge Line Size, R-410A  

Typical Arrangements

Figure 7

 illustrates a typical piping arrangement involving a 

remote air-cooled condenser located at a higher elevation than 
the compressor and receiver. This arrangement is commonly 
encountered when the air-cooled condenser is on a roof and the 
compressor and receiver are on grade level or in a basement 
equipment room.

Figure 8

 illustrates another very common application where 

the air-cooled condenser is located on essentially the same 
level as the compressor and receiver. The discharge line piping 
in this case is not too critical. The principal problem 
encountered with this arrangement is that there is frequently 

insufficient vertical distance to allow free drainage of liquid 
refrigerant from the condenser coil to the receiver.

Notice, in both illustrations, that the hot gas discharge line is 
looped at the bottom and top of the vertical run. This is done to 
prevent oil and condensed refrigerant from flowing back into 
the compressor and causing damage. The highest point in the 
discharge line should always be above the highest point in the 
condenser coil. It is advisable to include a purging vent at this 
point to extract non-condensables from the system.

The receiver is used when it is desired to have refrigerant 
storage capacity in addition to the pumpdown capability of the 
condenser.
