Description
The present invention relates to a heat storage sheet, a heat storage roof structure, a heat storage outer wall structure and a construction method using the same, specifically, a heat storage sheet capable of saving energy and improving comfort in an indoor residential environment, a heat storage roof structure using the heat storage, and heat storage The present invention relates to an outer wall structure and a construction method.
The purpose of the insulation of the building is to keep the indoor temperature of the building pleasant by preventing the warmth of summer and the chill of winter. However, even if the outside air is blocked through the insulation and the room temperature is kept in a comfortable condition, the actual temperature that a person feels may change. The feeling that a person feels hot or cold is not simply caused by room temperature, but by the combined effect of radiant heat and airflow.
In addition to insulation, the most important factor that determines the indoor environment of a building is the heat capacity of the building that determines radiant heat or airflow. A large heat capacity of a building means that it can absorb and store a lot of heat, which can slow down the rapid rise or fall of the room temperature even if the temperature difference between the outside air and the heating / cooling heat source are applied. For example, there is a big difference in the heat capacity of temporary structures made of corrugated iron and buildings made of concrete. Steel buildings quickly rise when the sun goes down and cool down as the sun goes down, but concrete or stone buildings can prevent the rapid change in room temperature by storing the heat around them. However, high heat capacity does not necessarily create pleasant conditions. If a material with a high heat capacity, such as concrete, absorbs a cold chill in winter, cold radiation can cause a loss of body temperature. Cold radiation refers to the phenomenon that when the temperature drops in the cold winter, the surface temperature of the wall is dropped and the body temperature is deprived of the cold wall. It is the same as the cold and spooky feeling when entering a concrete building in the cold winter. This phenomenon is because the material such as concrete has a high heat capacity, but the heat storage or heat dissipation is linear.
As such, when a building material is properly harmonized with temperature, radiant heat, and airflow in order to maintain the indoor environment of a building comfortably, problems such as windows and shields arise.
The present invention is to solve this problem, to increase the heat capacity of the building, but not linear heat storage, but to prevent the rapid temperature change of the indoor temperature through the latent heat accumulation at a specific temperature, saving energy and comfort of indoor living environment An object of the present invention is to provide a heat storage structure of a building that can be improved and a construction method thereof.
To this end, the heat storage structure of the building according to the present invention is a roof structure installed in the building, the bottom plate is installed on the cheolgolbo of the building, the heat storage sheet is installed on the bottom plate and includes a phase change material, installed on the heat storage sheet Insulation is characterized in that it comprises a waterproof sheet is installed on the insulation.
In addition, the heat storage structure construction method of the building according to the present invention is a method of construction of a roof structure installed in the building, the step of installing a bottom plate on the cheolgolbo of the building, the heat storage sheet containing a phase change material on the bottom plate is installed To do, the step of installing a heat insulating material on the heat storage sheet, characterized in that it comprises a step of installing a waterproof sheet on the heat insulating material.
In addition, the heat storage structure of the building according to the present invention is an outer wall structure installed in the building, the heat insulating material is installed between the steel frame or wooden pillars of the building, the heat storage sheet is installed on the heat insulating material and includes a phase change material, the heat storage It characterized in that it comprises a gypsum board is installed on the sheet.
In addition, the heat storage structure construction method of the building according to the present invention is a method of construction of the outer wall structure installed in the building, the step of installing a heat insulating material between the steel frame or wooden columns of the building, heat storage containing a phase change material on the heat insulating material Installing a sheet, characterized in that it comprises the step of installing a gypsum board on the heat storage sheet.
In addition, the heat storage sheet according to the present invention is characterized in that the non-woven fabric is impregnated with a heat storage material made of a phase change material.
According to the present invention, the heat storage structure of a building using a phase change material increases the heat capacity of the building, and does not store or release heat linearly, but uses a characteristic of latent heat to heat the temperature at a specific temperature (ie, phase transition temperature). Delay the change to keep the room temperature in a comfortable condition.
In addition, the heat storage structure of the building using the phase change material of the present invention is particularly effective in increasing the comfort of the indoor living environment as well as the effect of energy saving.

As such, latent heat refers to heat that absorbs or releases when a state of a substance transitions (ie, transitions from solid to liquid, liquid to solid, liquid to gas, and gas to liquid). In general, latent heat is greater than sensible heat (ie, heat absorbed or released by temperature change without phase transition). For example, water absorbs 80 kW (335J) of heat per gram of water (liquid) from 0 ° C ice (solid), which is equivalent to the heat required to raise the same amount of water from 0 ° C to 80 ° C. .
The present invention increases the heat capacity of the building by using such a phase change material in the heat storage structure of the building, not storing or releasing heat linearly, but using a characteristic of the latent heat temperature at a specific temperature (that is, phase transition temperature) By delaying the change, the indoor temperature is kept in a comfortable condition.
The indoor temperature at which a person feels comfortable is usually known to be 18 ~ 22 ℃, but when the use place and use is changed, the appropriate temperature is varied, it is necessary to change the temperature. The phase transition temperature and heat storage capacity of the phase change material are inherent in the material, so it is different for each material and a suitable material can be selected and used according to the purpose of use. The heat storage structure of a building according to the present invention mainly uses a paraffin-based phase change material as a heat storage material of a heat storage sheet. As the paraffin-based phase change material has various melting points, condensation points, and heat storage capacities as shown in Table 1, appropriate materials may be selected and used according to circumstances.
In order to confirm the heat storage characteristics of the phase change material used in the heat storage structure of the building of the present invention, a board in which the phase change material was mixed in the form of a heat storage sheet was fabricated, and an experiment was conducted using a chamber. 7 is a graph showing the surface temperature change of a board incorporating a phase change material.
As shown in Figure 7, the temperature inside the chamber was raised to about 36 ℃ and then left at room temperature and the surface temperature of the board over time was measured. At this time, the experiment was conducted on a board (PCM board) in which a phase change material was incorporated into a heat storage sheet and a general board that were not. The temperature inside the chamber corresponds to the room temperature. Here, the general board is a conventional gypsum board used indoors and the PCM board is a board manufactured by incorporating a heat storage sheet into the gypsum board.
As a result of the experiment, the PCM board with the heat storage sheet was found to have a temperature of about 1.5 ° C. lower than that of the general board when the chamber temperature was increased, and gradually decreased as compared with the general board when the chamber temperature was lowered. As such, a general board without a heat storage sheet linearly stores or emits heat, so a temperature change occurs rapidly. However, in a PCM board equipped with a heat storage sheet, a phase change material stores or emits heat in the form of latent heat at a phase transition temperature. Therefore, the temperature change is delayed. In other words, the PCM board has an advantage in maintaining a relatively comfortable room temperature.
On the other hand, if the heat capacity of the building is high, the room temperature does not change rapidly, but gradually changes over a certain time. However, even if the structure with high heat capacity is designed as heat insulation, the heat capacity of the building cannot be obtained. That is, in the heat insulation structure, the room temperature rises in a short time when the heating is turned on, and the room temperature decreases in a short time when the heating is stopped, so that the operation frequency of the heating apparatus is inevitably increased to maintain the proper temperature. According to the present invention, since the
So far, the heat storage structure of the building using the phase change material according to the present invention has been described through the examples. In the present specification and drawings, preferred embodiments of the present invention have been disclosed, and although specific terms have been used, these are merely used in a general sense to easily explain the technical contents of the present invention and to help the understanding of the present invention. It is not intended to limit the scope. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention can be carried out in addition to the embodiments disclosed herein.
The heat storage structure of the building using the phase change material of the present invention is particularly effective in increasing the comfort of the indoor living environment as well as the energy saving effect. In addition, the present invention can be usefully applied to a building that operates a 24-hour air conditioning system such as a hospital, a hotel, and a computer room, but in particular, a building that operates an air conditioning system at a specific time such as a department store, an office, or a shopping mall. Will appear large. In addition, the present invention is expected to be useful even when a time difference occurs in the supply and demand of heat, such as solar use.
