Description

Technical Field

[0001] The utility model relates to the technical field of intelligent appliances, in particular to a room temperature regulation system. Background Art

[0002] The room temperature regulation system can greatly adjust the indoor temperature to the expected temperature within a short time to achieve immediate comfort or process requirements.

[0003] Currently, the room temperature regulation system usually uses fan coils and heat exchange pipelines for cooling or heating. Among them, when the fan coil adjusts the indoor temperature, multiple temperature sensors are respectively arranged in different areas of the room to detect the current air temperature. The urgency of the temperature demand in each area is judged by the difference between the current air temperature detected by the temperature sensor and the target temperature, so as to adjust the air outlet strategy. For example, the difference between the current air temperature and the target temperature in each area is compared in real time, and the fan coil is controlled to blow to the area with the largest difference between the current air temperature and the target temperature, so as to avoid large temperature differences in different areas.

[0004] The defect of this structure is that the detection error of the current air temperature in each area detected by the temperature sensor is large, that is, the current air temperature is difficult to accurately obtain, and the urgency of the temperature demand in each area is difficult to accurately judge, resulting in poor accuracy of the air outlet strategy adjustment of the fan coil. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a room temperature regulation system. Since the heat exchange pipeline sequentially passes through each area, the heat exchange demand intensity corresponding to each area can be accurately judged by the inlet water temperature and the outlet water temperature of the heat exchange pipeline in each area, which helps to accurately adjust the air outlet strategy of the fan coil.

[0006] The above technical problem is solved by the following technical solutions:

[0008] Compared with the background art, the room temperature regulation system described in the present utility model has the following beneficial effects: A heat exchange pipeline is used to serially connect multiple areas of the target space into a whole in sequence. The inlet water temperature and the outlet water temperature of the heat exchange pipeline in each area are respectively detected by the inlet water temperature sensor and the outlet water temperature sensor in each area, and the detection error is relatively small. The controller can accurately judge the heat exchange demand intensity of each area according to the inlet water temperature and the outlet water temperature, and adjust the fan coil unit in real time according to the heat exchange demand intensity, thereby helping to accurately adjust the air outlet strategy of the fan coil unit and achieve rapid and uniform temperature adjustment. Moreover, it also reduces the number of pipelines used and the layout difficulty, thereby reducing the use and installation costs of the room temperature regulation system.

[0027] The following combines Figures 1 to 2 , and describes the embodiments of the present utility model.

[0028] According to the embodiments of the present utility model, as Figure 1 shown, a room temperature regulation system is provided, which mainly includes a heat exchange pipeline 1, a fan coil unit 2, and a controller.

[0029] The room temperature regulation system described in this embodiment is used to regulate the temperature of a target space. The target space includes multiple areas.

[0030] Furthermore, as Figure 1 shown, the heat exchange pipeline 1 sequentially passes through each area. The water inlet end and the water outlet end of the heat exchange pipeline 1 in each area are respectively provided with a water inlet temperature sensor 3 and a water outlet temperature sensor 4. The water inlet temperature sensor 3, the water outlet temperature sensor 4, and the fan coil unit 2 are respectively electrically connected to the controller. The water inlet temperature sensor 3 is used to detect the real-time water inlet temperature of the water inlet end of the heat exchange pipeline 1 in each area and transmit it to the controller. The water outlet temperature sensor 4 is used to detect the real-time water outlet temperature of the water outlet end of the heat exchange pipeline 1 in each area and transmit it to the controller. The controller determines the heat exchange demand intensity of each area according to the water inlet temperature and the water outlet temperature of each area, and controls the air outlet strategy of the fan coil unit 2 according to the heat exchange demand intensity of each area.

[0031] It can be seen that the room temperature regulation system of the embodiments of the present utility model uses a heat exchange pipeline 1 to sequentially connect multiple areas of the target space in series as a whole, and conducts unified heat exchange management. The water inlet temperature and the water outlet temperature of the heat exchange pipeline 1 in each area are respectively detected by the water inlet temperature sensor 3 and the water outlet temperature sensor 4 in each area, and the detection error is relatively small. The controller can accurately judge the heat exchange demand intensity of each area according to the water inlet temperature and the water outlet temperature, and adjust the fan coil unit 2 in real time according to the heat exchange demand intensity, thereby helping to accurately adjust the air outlet strategy of the fan coil unit 2 and achieve rapid and uniform temperature regulation. Moreover, it also reduces the number of pipelines used and the layout difficulty, thereby reducing the use and installation costs of the room temperature regulation system.

[0032] Specifically, the heat exchange pipeline 1 is generally laid horizontally on the bottom surface of each area. A heat exchange medium flows in the heat exchange pipeline 1, and the temperature of each area is adjusted through the heat exchange between the heat exchange medium and each area. Then, the controller controls the fan coil unit 2 to further achieve rapid temperature adjustment of each area.

[0033] The heat exchange demand intensity refers to the degree of demand for the temperature adjustment ability of the room temperature adjustment system in a specific area in order to achieve or maintain a predetermined temperature condition, such as comfort or process requirements. It reflects the urgency of the demand for heat energy or cold energy in this area at a specific time. The heat exchange demand intensity of the embodiment of the present invention is obtained according to the absolute value of the difference between the inlet water temperature and the outlet water temperature. The larger the absolute value of the difference between the inlet water temperature and the outlet water temperature, the higher the heat exchange demand intensity, and the greater the heat exchange demand in the corresponding area. The controller controls the fan coil unit 2 to improve the heat exchange capacity of this area.

[0034] It should be noted that the embodiment of the present invention does not limit the number of areas and the arrangement manner of areas in the target space. For example, the target space can be a supermarket, a closed workshop, etc. Each area can be divided into connected virtual areas, or can be divided into multiple independent indoor spaces by walls.

[0035] Exemplarily, as Figure 1 shown, the target space includes four connected areas, namely area A, area B, area C, and area D. Area A, area B, area C, and area D are divided by virtual demarcation lines. The total inlet end 101 of the heat exchange pipeline 1 first enters area A from the upper left of the target area, and then sequentially enters area B, area C, and area D. Finally, the total outlet end 102 of the heat exchange pipeline 1 leaves area D from the lower left of the target area.

[0036] It should be noted that the controller can select any existing controller according to needs. For example, the controller can select existing controllers such as a micro control unit (MCU), a central processing unit, and an electronic control unit (ECU). Of course, other conventional controllers can also be selected according to needs. The embodiment of the present invention does not limit this too much.

[0037] In addition, the embodiment of the present invention does not limit the inlet water temperature sensor 3 and the outlet water temperature sensor 4. For example, the inlet water temperature sensor 3 and the outlet water temperature sensor 4 can adopt conventional temperature sensors such as contact thermometers or infrared thermometers.

[0038] Since the controller needs to obtain the inlet water temperature and the outlet water temperature of each area, at least one inlet water temperature sensor 3 and one outlet water temperature sensor 4 need to be set in each area, resulting in a large number of sensors, a large amount of data to be collected, a large workload for the controller to process, and a high use cost.

[0039] In order to reduce the number of sensors and further lower the usage cost, in one embodiment, the heat exchange pipelines 1 in adjacent regions share the inlet water temperature sensor 3 or the outlet water temperature sensor 4. Only one inlet water temperature sensor 3 or one outlet water temperature sensor 4 needs to be set in adjacent regions, and the inlet water temperature of one region and the outlet water temperature of another region can be detected simultaneously. At this time, the shared inlet water temperature sensor 3 or outlet water temperature sensor 4 can be selectively set at the junction of adjacent regions.

[0040] Furthermore, in one embodiment, as Figure 2 shown, along the flowing direction of the heat exchange medium in the heat exchange pipeline 1, the outlet water temperature sensor 4 in the upstream region simultaneously serves as the inlet water temperature sensor 3 in the adjacent downstream region. Thus, the usage quantity of the inlet water temperature sensor 3 is saved, and the usage cost is reduced.

[0041] For example, if region A is the upstream region of region B, then the outlet water temperature sensor 4 in region A simultaneously serves as the inlet water temperature sensor 3 in region B, and the installation of the inlet water temperature sensor 3 in region B can be omitted. Additionally, since region A is the first region where the heat exchange pipeline 1 enters, region A has no upstream region, and both the inlet water temperature sensor 3 and the outlet water temperature sensor 4 need to be set in region A.

[0042] Or, in one embodiment, along the flowing direction of the heat exchange medium in the heat exchange pipeline 1, the inlet water temperature sensor 3 in the downstream region simultaneously serves as the outlet water temperature sensor 4 in the adjacent upstream region. Thus, the usage quantity of the outlet water temperature sensor 4 is saved, and the usage cost is reduced.

[0043] For example, if region D is the downstream region of region C, then the inlet water temperature sensor 3 in region D simultaneously serves as the outlet water temperature sensor 4 in region C, and the installation of the outlet water temperature sensor 4 in region C can be omitted. Similarly, since region D is the last region where the heat exchange pipeline 1 exits, region D has no downstream region, and both the inlet water temperature sensor 3 and the outlet water temperature sensor 4 need to be set in region D.

[0044] In one embodiment, as Figure 1 shown, the heat exchange pipeline 1 covers the bottom surface of each region, and the heat exchange pipelines 1 in each region are arranged in a meandering and circuitous manner to achieve uniform heat exchange in each region and realize rapid temperature adjustment.

[0045] Furthermore, in one embodiment, as Figure 1 shown, the heat exchange pipelines 1 in each region extend along the width direction of the region where they are located and are arranged along the length direction, that is, the heat exchange pipelines 1 are arranged in an S shape in each region to achieve complete coverage of the bottom surface of each region.

[0046] In one embodiment, the lengths of the heat exchange pipeline 1 from the water inlet end to the water outlet end in each area are the same, and the areas of each area are the same. That is to say, the heat exchange capabilities of the heat exchange pipeline 1 in each area are basically the same, which is convenient for the controller to determine the heat exchange demand intensity of each area and is also conducive to quickly and evenly adjusting the temperature of each area. Specifically, as Figure 1 shown, the target area is a square space. Virtual dividing lines are respectively formed at the midpoint of the length and the midpoint of the width of the direction space, dividing the target area into areas A, B, C, and D with the same area. The lengths of the heat exchange pipeline 1 in areas A, B, C, and D are the same, and the shapes are roughly the same.

[0047] If the heat exchange demand intensity of a certain area is high, the temperature difference between the water inlet end and the water outlet end of this area is large. The controller can judge the heat exchange demand intensity of the corresponding area according to the absolute value of the difference between the water inlet temperature detected by the water inlet temperature sensor 3 and the water outlet temperature detected by the water outlet temperature sensor 4. For example, if the heating-up demand of a certain area is high, then this area absorbs more heat through the heat exchange pipeline 1, resulting in a large difference between the water outlet temperature and the water inlet temperature of this area. On the contrary, if the heating-up demand of a certain area is low, then this area absorbs less heat through the heat exchange pipeline 1, resulting in a small difference between the water outlet temperature and the water inlet temperature of this area.

[0048] It should be noted that the number of fan coils 2 is not limited in the embodiments of the present invention either, and one, two or more can be selected and set as needed. When one fan coil 2 is provided, the fan coil 2 can be arranged at the top center position of the target space and is provided with a rotatable air outlet. If the heat exchange demand intensity of a certain area is high, the controller controls the air outlet of the fan coil 2 to blow air towards this area to improve the heat exchange capacity of this area.

[0049] In order to further improve the heat exchange capacity of each area, in one embodiment, as Figure 1 shown, at least one fan coil 2 is provided in each area. The fan coil 2 can be optionally arranged at the bottom, on the wall or at the top of each area. The controller independently controls parameters such as the air volume and air outlet time of the fan coil 2 in each area according to the difference between the water inlet temperature and the water outlet temperature in each area, so as to accurately adjust the temperature of each area.

[0050] Exemplarily, as Figure 1 shown, one fan coil 2 is provided in each area, and the fan coil 2 is arranged at the top center position of each area to achieve uniform heat exchange.

[0051] It should be noted that the heat exchange medium is not limited in the embodiments of the present invention, and any existing material can be selected as needed. In order to reduce the use cost, the heat exchange medium is generally cold water or hot water.

[0052] In one embodiment, as Figure 1 shown, the room temperature regulation system further includes a cold / hot water production device 5. The cold / hot water production device 5 is used to output hot water or cold water, such as boilers, heat pumps, cooling towers, etc. The cold / hot water production device 5 is provided with a water outlet, and the water outlet is communicated with the total water inlet end 101 of the heat exchange pipeline 1. A water outlet valve is arranged at the water outlet, and the output of hot water or cold water to the heat exchange pipeline 1 is controlled through the water outlet valve to achieve heat exchange and temperature regulation.

[0053] Further, in one embodiment, as Figure 1 shown, the cold / hot water production device 5 is provided with a water inlet, and the water inlet is communicated with the total water outlet end 102 of the heat exchange pipeline 1. A water inlet valve may also be arranged at the water inlet to control the recycling of the used cold water or hot water in the heat exchange pipeline 1 back into the cold / hot water production device 5. Specifically, the total water outlet end 102 and the total water outlet end 102 of the heat exchange pipeline 1 may be arranged on the same side so as to be respectively connected to the water outlet and the water inlet of the cold / hot water production device 5.

[0054] The used cold water or hot water in the heat exchange pipeline 1 can be recycled into the cold / hot water production device 5 through the total water outlet end 102 and the water inlet, reheated or cooled and then recycled again to save resources. Moreover, the residual temperature of the used cold water or hot water in the heat exchange pipeline 1 can also be utilized to improve the energy utilization efficiency.

[0055] Of course, in some other embodiments, the total water outlet end 102 of the heat exchange pipeline 1 may also directly discharge the used cold water or hot water directly to avoid polluting the cold / hot water production device 5.

[0056] The working principle of the embodiment of the present utility model is as follows:

[0057] The target space is divided into multiple regions of the same area in advance, and the heat exchange pipeline 1 connects the multiple regions in series in sequence. An inlet water temperature sensor 3 is arranged at the water inlet end of each region, and an outlet water temperature sensor 4 is arranged at the water outlet end. The inlet water temperature detected by the inlet water temperature sensor 3 and the outlet water temperature detected by the outlet water temperature sensor 4 are both transmitted to the controller. The controller determines the heat exchange demand intensity of each region according to the absolute value of the difference between the inlet water temperature and the outlet water temperature, and controls the air outlet strategy of the fan coil unit 2 in each region according to the heat exchange demand intensity of each region.

[0058] In the specific content of the above specific implementation manner, each technical feature can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should all be considered as the scope recorded in this specification.
