In an industrial building, several refuse hot-air flows (RHAF) are often available. We use a recovery heat exchanger (RHE) to heat incoming air for space heating by using a mixture of these RHAFs. A proper scenario for use of their heat contents is essential for efficient control of the energy system to achieve the greatest energy-saving efficiency. Software has been used in an industrial building...
A study has been carried out on heat recovery from air that ventilates a hot tool in a tool shop. The recovered heat is used to preheat air for space heating of this tool. Software has been used to analyze the heat-recovery efficiency and thermal comfort (TC) when the size and temperature of the hot tool are varied. An increase in hot tool size of 10% yields an energy loss of up to 2% and temperatures...
The authors use a recovery heat exchanger (RHE) in an industrial building to heat incoming air for space heating by using the heat contents of some of the refuse hot-air flows (RAF). Several RAFs are often available with different flow rates and temperatures. A proper scenario for use of their heat contents is essential for efficient management of the energy system. Using a steady-state, bottom-up...
