  • Method for recovering heat energy released by laundry machines
    Patent number: 8276292
    Abstract: 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.
