Piping Design 2
Standard HP: Y piping for heat pump application Refrigeration piping:
•All piping specifications must be followed to insure that the system will
operate properly.
• Maintain a minimum straight line distance: ≥ 20” before connecting to
a Y-joint.
• Minimum 36” straight line between Y-joints.
▪HR Changer: Mandatory device for indoor unit mode changeover
▪HR Changer is installed as the first device in the refrigerant piping
network. (Heat recovery only)
▪Cool-only indoor unit is connected to the HR Changer low pressure
gas and liquid outgoing pipes.
▪Sub MCU required for additional indoor unit zones after the HR
