Description

Building indoor temperature regulation system

This invention relates to a temperature regulating system, and more particularly to a temperature regulating system that is installed on a building and that utilizes the principle of thermal convection to reduce the temperature of the room.

In general, buildings are designed to open windows in the building in order to convect indoor and outdoor air. However, because the indoor space of a general building needs to have a convective heat dissipation effect, in addition to the airflow, the windows are required. The position of the opening and the direction of the airflow also need to be coordinated. However, the position of the window is limited by the conditions of the building itself, and it cannot be set as desired. The direction of the airflow is also limited by the natural environment. Therefore, the indoor temperature of the general building is difficult to borrow. The position opened by the window is lowered. In order to further reduce the indoor temperature of the building, it is possible to install a temperature regulating device such as an air conditioner, an air conditioner, or the like in the room. However, the known temperature adjustment equipments are some high-power electric appliances. Not only do they have considerable electricity costs, they do not meet the principle of energy saving and carbon saving. Generally, air conditioners cannot convect indoor and outdoor air, so long-term use for indoors Air quality also has a negative impact.

Partially enlarged view of the temperature regulation system One of the unpowered exhaust devices is associated with a hot gas flow conduit; and FIG. 3 is a cross-sectional view taken along line III-III of FIG.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1, 2 and 3, an embodiment of the indoor temperature regulating system of the present invention is mounted on a building 1, which may be a single floor or a plurality of floors as disclosed in Figure 1, i.e., The building 1 has a plurality of indoor spaces 11 arranged up and down. The indoor temperature regulation system includes: a hot gas flow line 2, and an unpowered exhaust unit 4 mounted on the hot gas flow line 2.

In the present embodiment, the hot gas flow line 2 includes a plurality of branch pipes 21 laterally and respectively disposed in the indoor spaces 11, a connecting pipe 22 connecting the branch pipes 21, and a position outside the room and blocking the communication. a mask 23 above the tube 22, each branch tube 21 has a plurality of convection ports 211 communicating with the indoor spaces 11, and the communication tubes 22 have an exhaust section 221 protruding from the top end of the building 1. The exhaust section 221 has an inner surface 223 defining an exhaust port 222, and an outer surface 224, and the mask 23 is located above the communication pipe 22, and prevents rainwater from being exhausted from the exhaust port 222 of the communication pipe 22. Enter the indoor space 11 of the building 1.

In this embodiment, the unpowered exhaust device 4 is disposed at the exhaust section 221 of the hot gas flow line 2, and includes an outer space around the exhaust section 221 of the hot gas flow line 2 and defines an annular space. An outer sleeve 41 of 40, a plurality of grounding surrounds the exhaust section 221 and located in the annular space 40 The inner temperature increasing element 42 and a temperature absorbing coating 43 coated on the outer annular surface of the outer tube sleeve 41.

Each of the temperature increasing elements 42 has a housing 421 and a phase change material 422 loaded in the housing 421. The phase change temperature of the phase change material 422 is also a melting point of 40 to 80 ° C. The 421 has two spaced end walls 423, a concave arc wall 424 connected between the end walls 423 and engaging the outer surface 224 of the exhaust section 221, and a connecting between the end walls 423. The outer concave arc wall 425. In the design, the outer concave arc wall 425 can change the curvature and fit the inner wall surface of the outer sleeve 41, or can be inserted between the outer concave arc wall 425 and the outer sleeve 41 as shown in the embodiment. An object that can conduct heat. In order to effectively adjust the indoor temperature of the building, the phase change material 422 is preferably a material having a melting point of 40 to 80 ° C. When the melting point of the phase change material 422 is lower than 40 ° C, the temperature difference between the melting point and the room temperature is small. However, a better convection effect cannot be produced; and when the melting point is higher than 80 ° C, it is necessary to absorb sufficient heat to melt the phase change material 422, so it is necessary to receive a higher temperature to achieve the heat storage effect.

The phase change material 422 is a heat storage material, and its main function is to absorb the high ambient temperature and store it. When the ambient temperature is lowered, the stored heat energy can slowly release the heat energy. The exhaust section 221 of the hot gas flow line 2 can be maintained at a high temperature for a long time. Preferably, the phase change material 422 is selected from the group consisting of: lithium nitrate dihydrate (LiNO ₃ ‧2H ₂ O), lithium nitrate trihydrate (LiNO ₃ ‧3H ₂ O), sodium carbonate decahydrate (Na ₂ CO ₃ ‧10H) ₂ O), sodium sulfate decahydrate (Na ₂ SO ₄ ‧10H ₂ O), potassium iron sulfate dodecahydrate [KFe(SO ₄ ) ₂ ‧12H ₂ O], calcium bromide hexahydrate (CaBr ₂ ‧ 6H ₂ O ), and lithium bromide dihydrate (LiBr ₂ ‧2H ₂ O), or a combination thereof. Specific combinations are: a combination of lithium nitrate trihydrate and sodium carbonate decahydrate, and a combination of sodium sulfate decahydrate and potassium iron sulfate dodecahydrate.

When the temperature around the exhaust section 221 rises, a temperature difference is generated between the exhaust port 222 and the indoor spaces 11 of the building 1, and since the hot air flows upward, the flowing hot air The flow causes suction so that air in the indoor space 11 of the building 1 flows in the direction of the exhaust port 222 via the convection ports 211. Incidentally, when the night comes, although the outdoor temperature is lowered, the phase change material 422 of the warming elements 42 can absorb heat and remain at 40 to 80 ° C, and when the outside temperature drops, the temperature rises. The phase change material 422 of the element 42 slowly releases the heat energy, so that the exhaust port 222 of the hot gas flow line 2 can also be at a high temperature at night and generate an upward hot air flow. Therefore, the embodiment can also Maintain temperature regulation at night.

It can be seen from the above description that the indoor temperature regulation system of the present invention is designed to utilize the unpowered exhaust device 4 in the hot air flow. The suction inside the pipeline 2 generates the air originally discharged in the indoor space 11 to achieve a better convection effect. Therefore, the invention not only has a novel structure, but also has the effect of automatically adjusting the indoor temperature without power.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
