Design and experimental study of an industrialized sunspace with solar heat storage

Energy efficiency and thermal behaviour of attached sunspaces, in the residential architecture in Spain. Summer Conditions

“…This prototype was compared to another sunspace without water accumulation and to a single window, through monitoring (summer 2011 and winter 2012) and simulation. In summer conditions, the best results were obtained in the prototype, and the worst in the single window, since the first has exterior solar protection, and provides better ventilation because of the better design of the outer sheet [8,9]. This research concluded that the use of the sunspace is closely linked to a design that allows adequate ventilation and solar protection in summer, and the importance of an active and adaptive use versus a static use, throughout the day.…”

Experimental Analysis of the Thermal Performance of a Sunspace Attached to a House with a Central Air Conditioning System

“…From 1 to 23 July, the air conditioning with dehumidification function was turned on (the air conditioning temperature was set at 27 °C) and the outside window of the sunspace was opened. From 23 August to 16 October, the air conditioning was turned on (cooling, the air conditioning temperature was set at 26 °C) and the outside window of the sunspace was closed. At this time, the air in the sunspace was sent to the air conditioning room only during the time when the temperature in the sunroom was lower than 24 °C.…”

“…Lu et al [15] studied the heating energy performance of a building with a PCM wall attached with a sunspace combined with a PCM floor on the campus of Tianjin University and proved that this heating system can effectively improve indoor temperature. Sánchez-Ostiz et al [16] studied the thermal energy performance of a house attached with a sunspace and concluded that in summer, adequate ventilation and solar protection systems are the keys to avoiding overheating caused by the sunspace. Bataineh et al [17] studied the thermal performance of a sunspace with an inclined front surface and proposed that the use of an inclined front surface with double glazing can further reduce the cooling and heating load demands.…”

Study on Heat Utilization in an Attached Sunspace in a House with a Central Heating, Ventilation, and Air Conditioning System

“…The results showed that the convective heat transfer from the sunspace to the interior can reduce heating energy up to 28%. Sánchez-Ostiz et al [17] carried out a numerical simulation and experimental study on the performance of an attached sunspace with vertical thermal storage and another with horizontal heat storage. They concluded that a sunspace with heat storage capacity can improve the interior thermal performance of the adjacent room compared to a simple sunspace or a window.…”
