Air-conditioning unit having a coil with an active portion and an inactive portion

An air-conditioning unit, comprising:

• an input vent configured to receive return air;
• an intermediate vent;
• an output vent;
• a blower fan configured to move the return air from the input vent to the intermediate vent;
• and
• an air-conditioner coil located between the intermediate vent and the output vent including
• an active portion configured to receive a first portion of the return air from the intermediate vent, to circulate a refrigerant, to condition the first portion of the return air by heat exchange with the refrigerant to create conditioned air, and to pass the conditioned air to the output vent, and
• an inactive portion that does not circulate the refrigerant and that is configured to receive a second portion of the return air and pass the second portion of the return air as unconditioned air to the output vent,
• wherein
• the conditioned air and the unconditioned air are passed through the output vent as supply air,
• the active portion includes two or more active segments arranged in parallel, each active segment providing a separate active refrigerant path through the air-conditioner coil, and
• the inactive portion includes two or more inactive portions arranged in parallel, each inactive segment providing a separate inactive refrigerant path through the air-conditioner coil, and
• no connection exists between any part of the inactive portion and a supply pipe for refrigerant.
