The paper presents various solutions for water loop heat pump systems. Systems with heat pumps connected by a water loop are an economically attractive proposition. They allow significant savings. In the winter months, they achieve up to 60% energy savings for shopping centers. On an annual basis, they reach up to 23%. It is also important to note the possibility of additional use of "free-cooling" cooling, which allows a significant reduction in operating costs or supplementing with solar panels as an additional heat source. In industrial systems, the potential of water loop heat pump systems allows for significant energy savings and positive environmental aspects.

Solution regeneration of the heat-source tower is significant to guarantee the normal operation of the heat-source tower. Mechanical vapor recompression system is an efficient system for evaporation of solution. In this paper, mechanical vapor recompression system is applied to regenerate solution of heat-source tower. To clarify the merits of mechanical vapor recompression solution regeneration system, several typical solution regeneration systems are modelled. As a result, mechanical vapor recompression shows 35.7%, 73.5% and 91.2% energy saving compared to air-driven heat pump, three-effect evaporating system, and single effect evaporating system, respectively. Furthermore, a heat-source tower heat pump with solution generation system is installed in a typical building in Yangtze river region. The whole heating season performance is simulated to find the effects of different solution regeneration system on the whole heat pump system. As a conclusion, the seasonal coefficient of performance of heat pump is decreased 1.6% by mechanical vapor recompression regeneration system. Comparatively, the seasonal coefficient of performance of heat pump is decreased 2.6%, 4.2% and 10.0% by air-driven heat pump, three-effect evaporating system, and single effect evaporating system, respectively. Practical application: Solution regeneration systems for heat-source tower heat pump systems have been applied in building projects especially in hot summer and cold winter zone in China based on previous investigation. A heat-source tower heat pump system combined with heat pump solution regeneration system has been applied in an office building in Changsha, Hunan Province in China. And its practical operation energy consumption has been reduced obviously compared with traditional single effect evaporation system. Therefore, it is of vital importance to demonstrate the operating performance of different solution regeneration systems applied in heat-source tower heat pump systems in building.

“…The spray drying is a process which has extensively been used to produce particulate products in different industries such as ceramic, and food [1][2][3][4][5][6][7][8][9][10]. These various applications have tempted the research community to conduct several researches on different aspects of this process [11][12][13][14][15][16][17][18][19][20][21]. The spray dryers are considered as energy intensive operations that consume a large portion of the applied energy to the industrial unit [22][23][24].…”

In this paper, the applicability of the heat exchangers for the heat recovery and energy saving purposes in spray dryers by utilizing Computational Fluid Dynamics (CFD) is investigated. For this purpose, two different tube-finned heat exchangers with the elliptical holes are added to the equipment. The first one gives the heat of the exhaust air and the second one translates the recovered heat from the exhaust air to the atomizing air. Initially, the effect of different parameters on the heat exchangers are studied. Then, numerically the effect of adding heat exchanger on the factory performance is evaluated. It is observed that by adding the mentioned heat exchangers, the energy consumption and energy price of the factory and the spray dryer decreases. Hence, the suggested equipment can be used for energy saving in the spray dryers.
