System performance of a residential building using the air-based solar heating system

Annual Heating and Hot Water Load Reduction Effect of Air-Based Solar Heating System Using Thermal Simulation

“…To investigate the accuracy of the calculation model of the air-based solar heat collector, the collector outlet temperatures from the experiment and simulation were compared under the same conditions of outside temperature, inlet temperature, and volume flow rate of air. Figure 4 shows the target collector of the experiment [20]. Table 6 shows the measurement instruments used in this study.…”

“…For these reasons, the use of air-based solar heating systems has increased rapidly in recent years in Japan, where convective heating is predominant. In PV/T systems, there is increasing research on the performance evaluation of systems using air as a thermal medium via experiments and simulations [19][20][21][22][23][24]. Recently, there has been an increasing amount of research on the proposal and performance evaluation of heating systems using an air-based solar heating system [25][26][27].…”

“…However, most of the studies on the air-based solar system to date have mostly focused on the performance of the system itself, rather than the effect of applying it to buildings [28][29][30]. In the case of solar energy, it is important to understand not only the performance of the system itself but also the performance when applied to a building, because it is available only for a certain period of time, is difficult to control, and the utilization efficiency changes depending on the conditions of the building [20].…”

Climate Classification for the Use of Solar Thermal Systems in East Asia

“…Using this Excel-based simulation method, it is possible to input mathematical equations into each cell and to refer to the values of other cells inputted by users. To eliminate heat transfer and heat accumulation effects between rooms, the buildings in the experiment were simple models, the same as that of the laboratory experiments in the reference study [4]. Figure 1 and Table 1 show the conceptual diagrams of the target building and simulation conditions.…”

“…More than 70% of the capacity of liquid-type solar collectors around the world are in China, and the use of solar heating in East Asia is rapidly increasing [3]. In addition, in Japan, the use of air-based solar heating systems is on the increase, as convective heating is usually utilized [4]. Extensive research has been conducted on collectors.…”
