PCT No. PCT/DK91/00166 Sec. 371 Date Dec. 17, 1992 Sec. 102(e) Date Dec. 17, 1992 PCT Filed Jun. 20, 1991 PCT Pub. No. WO91/19947 PCT Pub. Date Dec. 26, 1991.A method is presented for the transfer of heat from a low to a higher temperature, in that the main medium in gas form is heated and compressed, after which this main medium is conducted to a first heating chamber (1) where heat at low temperature is added to the main medium, whereafter the gas is conducted to a compressor (8) and compressed, in that before being conducted to the first heating chamber (1), the main medium can undergo a pressure drop and a possible heat absorption in a heat exchanger. In the first heating chamber (1), there is added an auxiliary medium in liquid form which evaporates together with the heating of the main medium, so that after the heating the main medium is more or less saturated with the auxiliary medium in vapor form, in that the heat is added from a second heating chamber (2) in which a gaseous medium containing evaporated auxiliary medium is cooled for the condensation of the auxiliary medium. A third heating chamber (14) can be used for the transfer of heat to the first heating chamber (1). |
