SPLIT HORIZONTAL INVERTER UNITS  

PACKAGED AIR-AIR 

REFRIGERANT LINES 

 

For more information on the dimensioning of the refrigeration lines, request document with reference 207682 Rev100. 
 

COOLING CIRCUIT

 

 

Split systems demand a correct disposition of refrigerant piping and a correct connection between both indoor and outdoor 
units.  

  Pressure drop of the line 

  Circulation speed of the refrigerant 

  Refrigerant mass 

 
 

DISCHARGE LINES

 

 
In heat pump operation, the low pressure line works as high pressure line. 

 

 

 
 

LINES POSITION

 

 

1.  When indoor unit is at a lower level than outdoor unit: 

 

It is not essential to install traps in the vertical line. However, it could be convenient to install some every 6 to 9 meters 
in order to help oil return. 

 

 

 
 

 

 

When working with the machines in operation, discharge line temperature is 

very HIGH and could hurt people.
