Heat Recovery and Comfort Cooling in place

heat-recovery-in-place-7th-aug.jpg There was just enough space in the eaves to fit the heat recovery and the comfort cooling units. The comfort cooling unit on the right re-cycles air in the room, passes it over a heat exchange matrix which uses the cold return feed from the heat pump to reduce the air temperature by about 7 degrees. So the return side of this has to be insulated (the sliver stuff). The heat recovery pipes only have to be insulated where it goes into “cold” spaces such between the rafters above the sheepswool insulation.
