Installing Refrigerant Lines in a Split Air Conditioning System

Which refrigerant lines must be field installed in a split air conditioning system with a remote condensing unit?

A) discharge and suction

B) liquid and suction

C) discharge and liquid

D) No lines need to be installed.

Final Answer:

In a split air conditioning system with a remote condensing unit, the discharge and liquid lines need to be field installed.

Explanation:

In a split air conditioning system with a remote condensing unit, the refrigerant lines that need to be field installed are the discharge and liquid lines.

The discharge line carries the hot refrigerant gas from the compressor to the condenser coils inside the heated space, while the liquid line carries the cooled refrigerant liquid from the outdoor evaporator coils back to the indoor unit.

The suction line, on the other hand, connects the indoor evaporator coils to the outdoor compressor unit and is typically pre-installed.

It is important to ensure proper installation of the discharge and liquid lines to ensure the efficient operation of the air conditioning system.
