At night, heat stored in the phase change material layer 21 conducts heat to the interior of a sunlight room in the form of heat radiation and heat convection so as to improve indoor temperature, the shading cloth 41 can effectively prevent the heat in the sunlight room from losing through a roof, a light-transmitting outer window 33 and the like, an air interlayer is formed between the shading cloth 41 and the heat storage wall body 2 and the light-transmitting outer window 33 by means of the fixation of the elastic hoop component 5 and the sliding rod piece 53 arranged in the invention to the shading cloth 41, the heat resistance between indoor air and outdoor air is increased, an air layer is formed between the shading cloth 41 and the light-transmitting roof 6, and the indoor heat can be reduced from losing to the outside through the roof. The heat insulation layer is arranged between the phase change material layer 21 and the heat storage wall body 2, so that the heat insulation performance of the whole heat storage wall body 2 is improved, the heat dissipation of the phase change material layer 21 to the outside through the heat storage wall body 2 is reduced, and the heat transfer between the outdoor environment and the indoor environment in the heat storage wall body 2 is also reduced. If the sunlight room has ventilation requirement in use, the light-transmitting outer window 33 close to the heat storage wall body 2 can be opened for short time to ventilate for short time.
An optimal control method of a sunlight room with phase-change heat storage is used for cooling the sunlight room with the phase-change heat storage in summer, and comprises the following operations:
when the intensity of solar radiation is not high, the shading cloth 41 can be taken down, and the curtain is opened, so that the sunlight room can be conveniently daylighted;
when the intensity of solar radiation begins to become stronger, the shading cloth 41 is placed on the cross rod 4, and the shading effect of the shading component 8 is added, so that solar radiation with large solar altitude angle in summer can be effectively prevented from entering the sunlight room, and the indoor temperature is reduced while the sunlight room is ensured to be transparent;
when the solar radiation is strong and the temperature of the heat storage wall body 2 is obviously increased, the indoor temperature is too high, the side windows 34 and the skylight 64 are opened, the shading cloth 41 is moved to enable the skylight 64 to be communicated with the air around the heat storage wall body 2, the air is heated on the surface of the heat storage wall body 2 and forms airflow with the external airflow entering and exiting from the side windows 34, the airflow carries the indoor heat in the sunlight room, and the heat flows out through the skylight 64 under the action of hot pressing of the air.
When the sun room is used in summer and the solar radiation intensity is not high, a user can select to take down the shading cloth 41 and pull open all the indoor curtains to ensure the light transmission effect;
with the intensity of solar radiation becoming stronger, the shading cloth 41 is placed on the cross bar 4 under the transparent roof 6, the shading component 8 at the south side of the sunlight room is used for shading the solar radiation with large solar altitude angle in summer, simultaneously, the sunlight with small altitude angle in winter is prevented from entering, the high-angle solar radiation entering the sunlight room in summer is also reduced, the requirement of a user on the light transmission of the sunlight room is ensured, the temperature in the sunlight room can be prevented from rising too fast, the use of the sunlight room in high and cold areas is considered, the intensity of the solar radiation in summer in the areas is stronger, the influence of the sunlight entering the sunlight room on the indoor temperature is larger, if the phase-change material layer 21 is exposed to the sunlight for a long time, the heat can be stored excessively, the indoor temperature can rise rapidly, at the moment, the indoor thermal comfort requirement can not be met only by various shading measures, the transparent outer window 33 can be opened, the shading cloth 41 bypasses the cross bar 4 which is farthest away from the heat storage wall body 2, the shading cloth 41 is placed on the cross rod 4 through extrusion of the self weight, air tightness and heat preservation near the roof are enhanced, the skylight 64 on the light-transmitting roof 6 is opened, at the moment, due to the fact that the temperature of air near the phase change material layer 21 is increased, temperature difference is formed between the air and air of other indoor parts, the air pressure of the part is relatively reduced, surrounding cold air can rapidly approach the periphery of the phase change material layer 21 and absorb heat of indoor air in a sunlight room, the air flows out through the skylight 64 under the action of hot pressing, heat in the sunlight room is rapidly taken away, air flowing out of the skylight 64 can be supplemented from the side window 34, air convection is formed, the temperature is prevented from being rapidly increased, and thermal comfort of the sunlight room is kept.
Through the structure and the optimization control method, the sunlight room has five optimization function effects of air tightness, light transmission, heat accumulation, heat preservation and ventilation by referring to a functional decomposition explanatory diagram of fig. 7, and also has a sun-shading cooling system under the conditions of high temperature and high illumination, and compared with the existing sunlight room, the sunlight room is a comprehensive control method for optimizing and controlling the thermal comfort degree.
