Cooling and heating balanced operation
KXR6 heat recovery systems - for simultaneous heating and cooling
The KXR6 system interconnecting pipework has a unique arrangement, with two of the interconnecting pipes routed through a
PFD Distribution Controller, and the third pipe connected directly to each indoor unit from the main pipe run. This reduces
installation time, and the number of brazed connections on site. The PFD Distribution Controllers are available for single
connection, or as a combined PFD 4-way connection, with each connected unit having independent cooling or heating operation.
During defrosting or during automatic protection of a compressor, which is activated every several hours in heating operation, heating operation temporarily
stops and restarts after some period. KXR6 series has the same automatic protection of compressor in cooling operation also. During this protection period air
flow only comes on and cooling operation restarts after some period.
