The use of at least one central heat exchanger to extract and dry the heat energy released by laundry machines, in particular their gland steam. The energy thus recovered can be fed back to the laundry machines as hot air or hot water. This represents a significant reduction in the energy requirements of laundry machines as laundry machines discharge a great amount of unused energy into the environment, which, particularly in light of rising energy prices, represents an unnecessary operational cost for a laundry.

1. A method for recovering heat energy released by a laundry machine, comprising the steps of: feeding the heat energy released by the laundry machine to a first heat exchanger (16), wherein the heat energy is in the form of moist hot air accumulating from the laundry machine,heating water with the heat energy in the first heat exchanger (16),dehumidifying the moist hot air in the first heat exchanger thereby converting the moist hot air into dry air and warm water,feeding the dehumidified dried air to the laundry machine, andcycling the warm water in a loop through a second heat exchanger (18), which heats a heat-transfer medium employed in the operation of the laundry machine. 2. The method according to claim 1, wherein the second heat exchanger (18) is arranged downstream of the first heat exchanger (16) and wherein the heat-transfer medium employed in the operation of the laundry machine is water heated by the second heat exchanger (18) and fed to the laundry machines. 3. The method according to claim 1, further comprising the step of converting the moist hot air conducted to the at least one heat exchanger (16, 18) into hot air. 4. The method according to claim 1, further comprising the step of converting the moist hot air conducted to the at least one heat exchanger (16, 18) into hot water.
