ductless serving multiple rooms

bus_driverAugust 9, 2014

They do make such systems, right? And it is clear that the unit within the room must have two refrigerant lines plus condensate drain. These could easily be on the exterior of the building.
If systems with one compressor/condensor unit serve multiple rooms, how are the refrigerant lines arranged? Do all the lines originate at the condensor or are refrigerant lines for individual rooms teed off at some point away from the condensor?
Thanks for clarifying this for me.

The condensing unit has 2, 3 or 4 sets of service valves depending upon model. You run your line SE from the condensing unit to each evaporator, the drain off the evaporator (indoor unit) and power from the condensing unit to each evaporator. For Fujitsu and others, but not all, it takes 14/3 wire. Go to fujitsugeneral.com and read for a while. Then report back. Mitsubishi and Daikin are the other majors.

You just need to take care by
ensuring that you don't mishandle the AC during switching off and on or while it is being set up.If you learn right care of your air unit, it will supply you with good service during its full lifetime
