Abstract
For the purpose of improving the utilization of remote heating grids, particularly for space air heating, at least one heat storage device is connected in series with the heaters of a hot water heating circuit, whereby the water conduit from the remote heating grid to the heating circuit can be operated 24 hours a day at its full capacity, so that for any given diameter of the conduit approximately twice the heat quantity previously transmitted can be transmitted with a consequent increase in the rating of the remote heating grid.
Claims6
A heating circuit including a heat supply circuit of a predetermined transmission capacity adapted to be supplied with a heat carrier supply medium from a remote heating grid, a heat user circuit containing a heat carrier user medium for withdrawing heat from said heat supply circuit including a plurality of heating elements where the transmission capacity of the user circuit is greater than said predetermined transmission capacity of the supply circuit, at least one heat exchanger for exchanging heat between said supply circuit and said user circuit, a first latent heat storage device having a first heat storage mass in heat conducting contact with said one heat exchanger and where said first mass experiences a phase change at a temperature below the temperature of said heat carrier medium coming from the remote heat grid whereby heat supplied by said heat carrier medium may charge said heat storage mass during periods of low withdrawal of heat by said heat user circuit, a second heat exchanger for exchanging heat between said supply circuit and said user circuit and a second latent heat storage device containing a second heat storage mass in heat conducting contact with the second heat exchanger and where the second mass has a lower phase change temperature than the first mass and whereby said first heat exchanger is positioned upstream of said second heat exchanger with respect to the direction of flow of said heat carrier medium from said remote heating grid.
