Combined heating and cooling networks with waste heat recovery based on energy hub concept

Waste heat recovery can help reducing operation costs and greenhouse gas emissions. In the present work, an “energy hub” template was employed to design combined heating and cooling networks in which heat pumps can be used to recover heat from the cooling loop and supply it to the heating loop. Heating and cooling loads of the network can be satisfied by natural gas boilers, electric boilers, chillers, and heat pumps. The design of the system...
