... and are the major contributors to the rejected exergy. Using the waste heat for space heating is evaluated. Based on fuel consumption in the boiler, the annual energy for space heating is estimated at 8.5 TJ. Theoretically, waste heat from the boiler flue, polypropylene dryers, and plant vacuums could meet up to 39...

.... If a heat storage system has to operate at atmospheric pressure, then the application of MgSO 4 ⋅ 7 H 2 O for seasonal heat storage is possible for space heating operating at 25 ° C and a water vapor pressure of 2.1 kPa. Initial experiments at the ECN (curve 3 in Fig. 4 ) were performed at 25 ° C...

The solar combi systems are initially equipped with heat exchanger spirals and direct inlets to the tank. A step-by-step investigation is performed demonstrating...

... at a higher temperature is used to provide any additional heat needed to meet the space heating load. The simulation models developed are then used to compare the performance of the forced-air and radiant floor systems based on maintaining the same operative temperature inside the space. It is found...
