Description

Air-conditioning system and method for temperature regulation of building materials

The invention relates to a temperature control system, in particular to a building material temperature control system, which can make good use of three heat transfer modes such as conduction, convection and radiation, and provide users with a natural and comfortable environment.

Radiation cooling (warming) refers to reducing (rising) the temperature of one or more surfaces of an object to form a cold (hot) radiating surface, and relying on the radiant heat exchange between the radiating surface and the human body, space and objects for cooling (warming). Technical method; usually the radiating surface is generated by providing cold (hot) pipes on the surface of the board to provide a cold (warm) effect. In terms of human comfort, temperature radiation is a slow heat exchange that does not agitate the air, and the heat exchange will be concentrated at the height of the person, directly affecting the human body, and retaining a proper amount of water in the space, thereby achieving a more comfortable With stable body surface temperature. Therefore, radiant cooling (warm) is generally applicable in dry climate environments, but in high humidity climate environments, water molecules in the air are likely to condense and affect its function.

In a traditional radiant roof cooling system (also known as a cold beam-column system), the ceiling of a room is provided with cold water pipes. The cold water pipe is close to the ceiling surface or installed in the panel to cool the room through natural convection and radiant heat transfer. However, water molecules in the air are likely to condense and accumulate on the cooler ceiling surface, and the materials that damage the ceiling need to be matched with a wind treatment unit to handle the indoor humidity. Radiant heating systems are usually represented by underfloor heating systems. Conventional underfloor heating is divided into two categories, plumbing and electric heating. However, plumbing usually pays attention to the quality and maintenance of water pipes, and it is difficult to handle water pipe ruptures. Although electric heaters can be installed under various floor building materials, electric heaters have local overheating, The three major risks of leakage, electromagnetic waves, and extreme power consumption cannot meet the needs of energy conservation and carbon reduction. The underfloor heating system is a commonly used building facility in high-latitude cold regions, but it is still not popular in countries such as Taiwan and other non-high-latitude cold regions; extreme climates formed by global warming and climate change, such as warm winter mixed with strong cold The severe temperature difference caused by the cold floor is likely to cause human diseases, especially for cardiovascular disease or the elderly population, there will be a risk of rapid contraction of blood vessels. In addition, Taiwan ’s demand for underfloor heating is not recurring. Conventional electric heating and plumbing are already an economic burden on laying, and the humid and rainy climate is not conducive to the maintenance of conventional electric heating and plumbing systems.

The purpose of the present invention is to provide an air conditioning system for building materials temperature regulation, which makes full use of three types of heat transfer methods such as conduction, convection and radiation. The applied field can achieve better comfort, and effectively use energy and reduce power / Electricity cost, convenient maintenance.

To this end, the present invention provides a building material temperature control air conditioning system, which includes a building material unit, a channel unit, a heat source unit, and a control unit. The building material unit is arranged in an indoor space and has a building material and a plurality of supporting members supporting the building material. The channel unit is adjacent to one side of the building material, and has at least one inlet, at least one outlet, and at least one air duct; wherein the air duct is defined by the inlet, the outlet, and the support members. The heat source unit communicates with the entrance of the aforementioned channel unit. The control unit has a microcontroller, at least one temperature sensor, and a human-machine interface. The temperature sensor obtains at least one detected temperature in the indoor space; the human-machine interface receives an expected temperature; and the microcontroller is electrically connected to the heat source unit. In this way, the microcontroller determines a target heat according to the detected temperature and the expected temperature, and causes the heat source unit to output the target heat. After receiving the target heat through the heat source unit, the gas enters the air duct, and the building material is adjusted to a target temperature along the air duct.

To this end, the present invention provides an air conditioning method for temperature regulation of building materials, including: (a) setting The air-conditioning system with the aforementioned building material temperature adjustment; (b) obtaining the expected temperature from the human-machine interface and the detected temperature of the indoor space from the temperature sensor; (c) determining a target heat according to the expected temperature and the detected temperature; and ( d) Drive the heat source unit to output the target heat.

Please refer to FIGS. 1 and 2 at the same time, which is an air conditioning system 10 for temperature regulation of building materials of the present invention applied to an indoor space 22. The indoor space 22 is formed by a plurality of partition surfaces 24. The partition surface 24 can be defined as a floor, a ceiling, a wall surface, an office light partition, a stairwell, or a specific object. The partition surface 24 is only used.

As shown in FIG. 1, the air conditioning system 10 for building material temperature control includes a building material unit 12, a passage unit 14, a heat source unit 16, and a control unit 18. Building material unit 12 along the interior space 22 At least one partition surface 24 is laid out, as shown in FIG. 2, and the partition surface 24 laid out by the building material unit 12 is usually ground when used as heating or floor heating. Please refer to FIGS. 3A and 4 together. The building material unit 12 has at least one building material 122 and a plurality of supporting members 124 supporting the building material 122. The channel unit 14 has at least one inlet 142, at least one outlet 144, and at least one air duct 146. As shown in FIG. 2, the heat source unit 16 communicates with the inlet 142, and the position of the outlet 144 is set according to the design for guiding the hot airflow. The control unit 18 has a microcontroller 182, at least one temperature sensor 184, and a man-machine interface 186. The microcontroller 182 is electrically connected to the heat source unit 16 in a wired or wireless manner.

The building material 122 defines a first side 122a and a second side 122b. In this embodiment, the building material 122 is close to the ground with the second side 122b, and the aforementioned supporting member 124 is provided on the second side 122b of the building material 122. The channel unit 14 is adjacent to the building material 122 and is on the same side as the aforementioned support member 124, so that the aforementioned support member 124 is laid in the channel unit 14; usually, the channel unit 14 and the building material unit 12 are matched with each other for group application. The air duct 146 is defined by the inlet 142, the support member 124, and the outlet 144, and has a blowing direction I. For example, in this embodiment, the air duct 146 is jointly formed by the building material 122, a floor corresponding to the building material 122, and the aforementioned supporting members 124 laid in the channel unit 14. Through heat flow simulation and / or experiments, the optimal configuration of the aforementioned support members 124 in the channel unit 14 can be obtained to achieve the most uniform heat transfer. Figures 3A and 4 show a configuration of the aforementioned supporting members 124. As an example, the aforementioned supporting members 124 are arranged in a direction perpendicular to the air supply direction I. The left and right supporting members 124 are spaced apart from each other. 124 is staggered. These layout methods can form a slower wind speed in the air duct 146, and can uniformly regulate the temperature of the building material 122.

Referring again to FIG. 2, the heat source unit 16 includes a heat exchanger 162 and an air duct 164 that connects the heat exchanger 162 to the inlet 142 of the air supply unit 14. The gas increases the temperature through the heat exchanger 162, and is driven by a fan (not shown) in the air guide duct 164 to enter the air duct 146. The hot air passes through the air duct 146 to regulate the temperature of the building material 122. The air duct 164 is used to maintain the speed of the air outlet. The wind speed of the air outlet is usually maintained within 2m / s to reduce noise and avoid dust and interfere with the cleanliness of the indoor space 22. Moreover, maintaining an appropriate air speed can also The forced convection of the micro airflow occurs in the indoor space 22 (generally, the wind speed is below 0.8 m / s). The temperature sensor 184 obtains one of the detected temperatures T _{A of the} indoor space 22, and the temperature sensor 184 can be located anywhere in the indoor space 22, such as directly attaching the building material 122, the exit 144 of the passage unit 14, or the distance from the building material 122 Height and so on.

Since the building material 122 reaches a target temperature T _G after heating, the indoor space 22 is radiated to regulate the temperature. Therefore, a temperature gradient occurs due to the distance of the air duct 146 from the inlet 142 to the outlet 144 and the height from the building material 122. . The detected temperature T _{A is} at least related to a predetermined height H of the temperature sensor 184 from the building material 122 and a predetermined distance D of the temperature sensor 184 from the entrance 142 of the channel unit 14, and the foregoing relationship can be simplified by T _G = T _A + X indicates that X is a temperature difference affected by variables such as a predetermined height H and a predetermined distance D; the foregoing information and the foregoing association are stored in the microcontroller 182. The man-machine interface 186 receives a desired temperature T _E set by the user, and the microcontroller 182 determines a target heat Q _G according to the temperature difference between the expected temperature T _E and the detected temperature T _A , so that the heat source unit 16 drives a target mass. Heat transfer medium (not shown) to achieve the output of the target heat Q _G , so that the building material unit 12 gradually reaches the target temperature T _G , and finally can reach the detection temperature T _A and the expected temperature T _E. Compared with the lack of conventional water and electric heating systems, the air conditioning system 10 for temperature control of building materials according to the present invention can achieve the temperature regulation and general energy of building materials 122 only by gas circulation, and can avoid the lack of the prior art.

Referring to FIG. 3B, in the channel unit 14, another arrangement relationship between the aforementioned support member 124 and the air supply direction I enables the channel unit 14 to form a single inlet 142, a single outlet 144, and a single air duct 146.

The air velocity has been maintained at 2m / s, the cross-section A of the air is 0.1m ² , the temperature of the gas entering the heat exchanger 162 is 20 ° C, the temperature of the gas leaving the heat exchanger 162 is 35 ° C, and the temperature difference ΔH is 15 ℃, the gas flow rate used to pass through the heat source unit 16 is estimated to be 11.76 m ³ / min.

Step S108: The control unit 18 causes the heat source unit 16 to drive a heat transfer medium of a target mass to achieve the output of the target heat Q _G. The steps S104 to S108 are repeated, so that the building material 122 gradually reaches the target temperature T _G.

In step S106, the corresponding predetermined distance is further set. A temperature gradient of D determines the target heat Q _G.

The temperature gradient of the height H or the predetermined distance D and the expected temperature T _E determine the target heat quantity Q _G. Therefore, each detected temperature T _A can be used as a check point to check whether the expected temperature T _E has been reached.
