Heat pumps - compact arrangement with an integrated primary energy - heat source for the controlled ventilation and heat energy supply of low - energy - buildings or passive houses are now being

摘要

The heat pump compact device (16) for ventilation and heat energy supply of buildings (15) has a heat exchanger (5), a heat pump (6) connected after the heat exchanger, an outside air flow as well as a building air flow into the heat exchanger. An exhaust as well as an admission air flow exit out of the heat exchanger and enter the heat pump, from which in turn a building admission air flow and exhaust air flow emerge. t least one primary energy heat source (7) is provided which heats up the building exhaust air flow before entry into the heat exchanger.
