2. Cogeneration - Wikipedia

   en.wikipedia.org/wiki/Cogeneration

   Combined heat and power (CHP) plants recover otherwise wasted thermal energy for heating. This is also called combined heat and power district heating. Small CHP plants are an example of decentralized energy. [2] By-product heat at moderate temperatures (100–180 °C (212–356 °F) can also be used in absorption refrigerators for cooling.

3. Micro combined heat and power - Wikipedia

   en.wikipedia.org/wiki/Micro_combined_heat_and_power

   A micro-CHP system usually contains a small heat engine as a prime mover used to rotate a generator which provides electric power, while simultaneously utilizing the waste heat from the prime mover for an individual building's space heating and the provision of hot domestic water. [2]

4. District heating - Wikipedia

   en.wikipedia.org/wiki/District_heating

   The Spittelau incineration plant is one of several plants that provide district heating in Vienna, Austria. Animated image showing how district heating works. District heating (also known as heat networks) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water ...

   In 1982 “Energy Raiser” the first multi-purpose unit for combined heating and cooling in 4-pipe systems is launched on the Market. In 1990 The “Free Cooling Liquid Chillers” are introduced for process and computer room cooling.

6. District cooling - Wikipedia

   en.wikipedia.org/wiki/District_cooling

   There are also 5th generation district heating and cooling systems (so called cold district heating networks) that are able to provide both heating and cooling simultaneously. In these systems the waste heat from chillers can be recycled and used for space heating or hot water production. [2]
