The direct surface heating/cooling system disclosed in DE 3936332 solves the problem of an economical domestic hot water supply and of heating cellars to a comfortable temperature in that the superheat of a compressor (1) is transmitted through a heat exchanger (11) to the water in a water heater (12), and the floor of the cellar is then warmed by the condensation heat. Due to the low condensation pressure, a heavy-duty evaporator (23) can draw the required evaporation heat all year round from the ambiend air, which is thus not laden therewith but relieved thereof. When floor (30) and/or ceiling (29) are air permeable and provided with tubes (4', 43), not only the room concerned, but also the incoming/outgoing air, are heated/cooled. A capillary ceiling (29) absorbs through capillaries the condensate produced in the case of cooling and if necessary heats, evaporates and discharges it into the outer air by means of an air conveying arrangement (31). |
