Abstract
In a heat exchanger of the kind used for the transfer of heat from exhaust air, e.g. from rooms, to fresh air to be led into rooms, or for the transfer of heat the opposite way, means (9) for the cooled exhaust air are arranged after the outlet (4) with a view to transferring heat from the exhaust air to a heat reservoir (12), i.e. a heat pump circuit (10, 11). The thermodynamic efficiency is dependent on the difference in temperature, of course, and by transferring heat from exhaust air to for instance a water tank for hot water, the temperature being in some places close to the flow temperature of tap water, it will be possible to make use of much more of the latent heat of the exhaust air.
Claims6
A heat exchanger system in a house arranged for the transfer of heat from exhaust air into fresh air to be supplied to the house or the transfer of heat in the opposite manner comprising means for creating a flow of exhaust air from the interior of the house, means for further creating a flow of fresh air from the outside to the interior of the house, means arranged to receive said exhaust flow and create a heat exchange relationship with the flow of fresh air, means connected downstream of said heat exchanger means for further cooling the flow of exhaust air exiting therefrom said further cooling means includes a heat pump circuit, said heat pump circuit having an evaporator being arranged in the flow of the exhaust air from said heat exchanger means and a condenser operatively connected to said evaporator and wholly submerged in the water of a water tank which is a tank holding hot tap water for the house, said condenser heating the tap water of the tank in response to the action of said condenser cooling the flow of exhaust air.
