Typically, a great deal of heat is wasted in the drainage systems of large-scale public shower facilities, such as those in schools, barracks, and natatoriums. This paper enhances a heat pump system used in public shower facilities for exhaust heat recovery. The system consists of three sections...

In the district heating system, the AHE (Absorption Heat Exchanger) can transfer the heat of the primary network with a large temperature drop to the secondary network with a small temperature lift in a heating station. Triangular heat transfer processes exist in a traditional AHE, and limit the...

The heat and mass transfer characteristics of a water permeable membrane were studied to determine appropriate selection criteria for such a membrane in a heat recovery ventilator (HRV). A general physical model was developed to analyze the performance of various types of membrane based HRVs....

The main task of HVAC systems in the cooling condition is to remove heat from indoor environment to outdoor environment. HVAC systems are complex networks of various processes, e.g., heat transfer, heat–work conversion, heat–humidity conversion, etc. These processes correspond to equipment...

Due to the huge thermal mass of buildings and the district heating (DH) network, room temperatures in buildings do not change much when the heat output from the heat source varies significantly during the day. Therefore, a combined heating and power (CHP) plant can vary its power output during...
