WebInduction heating is generally used to heat the ‘work’ directly, that is the induced currents flow in the electrically conducting object being heated. However, there is an important and growing series of applications where induction heating is used to heat a vessel or container from which heat is transferred by conduction to a non-metal product. Web10 de abr. de 2024 · When the building's heating energy consumption gradually decreases, the distributed heat pump unit can replace the coal-fired boiler to supply the peak heat load demand. In the future, China's district heating systems can be gradually changed from the current CHP and coal-fired boilers to CHP and distributed heat pumps.
