Description

Technical Field

[0001] The present invention relates to the technical field of regional cooling and heating systems, and in particular to a regional cooling and heating system with automatic heat management in a temperature control zone. Background Art

[0002] In the fields of industry, construction, medical care, etc., it is usually necessary to manage and temperature control certain areas at different times and in different areas. However, when some old areas were first built, due to various factors such as design, investment, market and space, the automatic energy management function was not realized, and it was difficult to meet the diverse temperature control and energy needs of users. In order to ensure the normal operation of energy-consuming areas, only simple and extensive control can be carried out on non-energy-consuming areas, or no control can be carried out at all, which greatly increases the waste of system energy.

[0003] In this case, in order to reduce energy consumption in non-energy-consuming areas, the best way to deal with the situation where there are multiple different energy-consuming areas in the area is: when the energy load of the temperature-controlled area needs to change according to the temperature, the temperature adjustment preset algorithm can be used to automatically adjust the amount of cold / heat delivered to each temperature-controlled area, thereby playing a role in regional temperature management; when the energy load of the temperature-controlled area needs to change according to the time period, the time for heat delivery to each temperature-controlled area can be automatically adjusted through the time preset algorithm, thereby playing a role in temperature management by time period; when the energy load of the temperature-controlled area needs to change according to the area, the flow adjustment preset algorithm can be used to automatically adjust whether each temperature-controlled area delivers heat, thereby playing a role in regional temperature management.

[0004] Therefore, if there is an automatic thermal management method that can automatically meet the user's temperature control needs and realize diversified and regionalized adjustment of temperature control zones, it can not only reduce energy waste in non-energy-consuming areas, but also make full use of automation means to accurately and real-time adjust the energy consumption of the entire system and form an established temperature control strategy to achieve overall automated thermal management.

[0040] The beneficial effects of the present invention are:

[0041] 1. The system proposed in the present invention is particularly suitable for scenarios where the system needs to be managed and temperature-controlled in different time periods and different areas; the automatic heat management system can automatically meet the temperature control and energy requirements of the temperature-controlled area, while solving the problem that traditional old regional cooling and heating systems are difficult to achieve load-sharing and regional regulation. At the same time, it analyzes environmental data and control data and forms an established temperature control strategy to achieve overall automated heat management.

[0042] 2. The present invention provides three adjustment methods under different energy usage modes: when the energy load required by the temperature control area is different, the upper computer temperature preset algorithm and adjustment measures can be used to achieve local area temperature adjustment, especially in the cooling mode, the temperature and humidity dual adjustment of the temperature control area can be achieved through this adjustment measure; when the temperature control area uses energy in different time periods, or when the temperature control area has energy-using and non-energy-using areas in the same time period, the temperature control area can be automatically managed by timing adjustment or zoning adjustment methods; in addition, the temperature difference adjustment method set according to the energy usage characteristics provides a large flow and small temperature difference forced energy adjustment measure, which further reduces the energy consumption of each link in the energy usage process and gives full play to the maximum advantage of passive energy regulation of the regional cooling / heating system.

[0043] 3. The present invention can utilize the fan to output wind power by arranging a heat transfer device. The airflow is heated or cooled by the water supply pipe of the regional cooling and heating system and the return pipe of the regional cooling and heating system, and diffused to various parts of the temperature control area to ensure the efficiency and effect of heat transfer and improve practicality. By arranging a wind convergence mechanism, the airflow output by the fan can be converged for directional transmission, and the transmission distance is improved to meet different usage requirements.

[0044] 4. When the plug-in board rack is inserted into the gap between the side bracket and the C-shaped frame, the second latching teeth are kept in meshing state with the first latching teeth under the action of the spring force, thereby achieving the purpose of fixing the plug-in board rack and improving reliability.

[0045] 5. The present invention can squeeze the ball toward one side of the arc-shaped rubber pad when the plug-in plate rack is inserted into the gap between the side bracket and the C-shaped frame, causing the arc-shaped rubber pad to deform, thereby increasing the friction between the ball and the arc-shaped rubber pad. In addition, preferably, the contact surface between the plug-in plate rack and the ball is set as an anti-slip surface, and the friction between the ball and the arc-shaped rubber pad is increased due to pressure, thereby preventing the C-shaped frame from sliding on the water supply pipe of the regional cooling and heating system, thereby improving the stability of the fan. When the position of the fan needs to be adjusted, it is only necessary to remove the plug-in plate rack and contact the pressure on the ball to reduce the friction, thereby being able to conveniently adjust the position of the C-shaped frame and the fan, thereby improving practicality.

[0046] 6. The present invention can select a corresponding guiding sleeve, pass one end of the guiding rod through the second plug-in frame and install it in the guiding sleeve. Thus, under the support of the guiding rod, the angle corrugated cylinder deforms, making the angle of the angle corrugated cylinder adapt to the guiding sleeve, so as to achieve the purpose of adjusting the air flow output angle and improve the practicability. By setting the plug and the slot, it can be disassembled and assembled conveniently. When adjustment is needed, rotate the first fixing ring and insert the plug into different slots, so as to change the positions of the respective guiding sleeves to improve the adjustment flexibility.

[0061] Embodiment 1:

[0062] A district cooling and heating system with automatic heat management in the temperature control area, such as Figure 1 shown, which includes an automatic heat management system 1 and a district cooling and heating system 2. The automatic heat management system 1 includes a temperature control area data acquisition device 21, a data transmission device 22, and a host computer 18; the district cooling and heating system 2 includes a temperature control area 23, a cold and heat source host 16, and a circulating pipeline mechanism;

The host computer 18 can send adjustment instructions to the temperature control area data acquisition device 21 through the data transmission device 22 according to the preset adjustment instructions, so as to remotely adjust the energy consumption structure and energy consumption mode of the temperature control area 23.

[0067] For the convenience of cooling and heating; such as Figure 1 shown, among them, the circulating pipeline mechanism includes a district cooling and heating system water supply pipe 3, a district cooling and heating system return water pipe 4, and a circulating pump 15. The cold and heat source host 16 conveys cold and heat to the temperature control area 23 through the district cooling and heating system water supply pipe 3 and the district cooling and heating system return water pipe 4. The circulating pump 15 is installed on the district cooling and heating system water supply pipe 3 or the district cooling and heating system return water pipe 4 as the source of the transmission and distribution power.

The pressure sensor 6 is installed on the water supply pipe 3 of the district heating and cooling system, and the humidity acquisition device 9 is arranged in the temperature control zone 23. The pressure sensor 6 and the humidity acquisition device 9 are respectively connected to the data input end of the terminal PLC controller 12 through a control cable 14.

[0069] When this embodiment is in use:

[0070] When the energy consumption loads required by the temperature control zone 23 are different: When the system operates in the cooling mode, when the indoor temperature T1 of Building 1 in the temperature control zone 23 needs to be lower / higher than the indoor temperatures Tn of other controlled buildings, the upper computer 18 performs mathematical analysis and control linkage on the temperature data of Building 1 in the temperature control zone 23 collected by the terminal PLC controller 12, and sends a temperature reduction instruction to the terminal PLC controller 12 through the serial port server 17 using the data transmission device 22. The terminal PLC controller 12 receives the temperature reduction adjustment instruction and adjusts the opening degree of the electric control valve 5, thereby increasing / decreasing the distribution flow rate of the water supply pipe 3 of the heating and cooling system, and reducing / increasing the indoor temperature T1.

[0071] When the indoor humidity RH1 of Building 1 in the temperature control zone 23 needs to be lower / higher than the indoor humidities RHn of other controlled buildings, the upper computer 18 performs mathematical analysis and control linkage on the humidity data of Building 1 in the temperature control zone 23 collected by the terminal PLC controller 12, and sends a humidity reduction instruction to the terminal PLC controller 12 through the serial port server 17 using the data transmission device 22. The terminal PLC controller 12 receives the humidity reduction adjustment instruction and adjusts the opening degree of the electric control valve 5, increasing / decreasing the distribution flow rate of the water supply pipe 3 of the cooling system, and reducing / increasing the indoor humidity RH1 in the temperature control zone by using the principle of cooling and dehumidification.

[0072] When the system operates in the heating mode, when the indoor temperature T1 of Building 1 in the temperature control zone 23 needs to be higher / lower than the indoor temperatures Tn of other controlled buildings, the upper computer 18 performs mathematical analysis and control linkage on the temperature data of Building 1 in the temperature control zone 23 collected by the terminal PLC controller 12, and sends a temperature increase instruction to the terminal PLC controller 12 through the serial port server 17 using the data transmission device 22. The terminal PLC controller 12 receives the temperature increase instruction and adjusts the opening degree of the electric control valve 5, increasing / decreasing the distribution flow rate of the water supply pipe 3 of the heating system, and increasing / reducing the indoor temperature T1.

[0073] When the buildings 1-n in the temperature control area 23 consume energy at different times, preset the start and stop times of the cooling and heat source host 16 and the circulation pump 15 according to the energy consumption time in the host computer 18, and use the data transmission device 22 to send start / stop instructions to the terminal PLC controller 12 through the serial port server 17. The terminal PLC controller 12 receives the instructions and adjusts the start / stop time of the electric control valves 5 of each building in the temperature control area 23. Moreover, the host computer 18 preset the delay linkage function of the start / stop time of the electric control valve 5 and the cooling and heat source host 16 and the circulation pump 15 according to the control linkage logic of the regional heating and cooling system 2, which not only meets the timing adjustment of the overall energy consumption at different times, but also reduces the energy waste during the non-energy consumption period.

[0074] When there are energy-consuming and non-energy-consuming areas in each building 1-n of the temperature control area 23 at the same time, preset the start / close times of the electric control valves 5 of each building in the temperature control area 23 according to the energy-consuming areas in the host computer 18. The host computer 18 uses the data transmission device 22 to send start / stop instructions to the terminal PLC controller 12 through the serial port server 17. The terminal PLC controller 12 receives the instructions and starts / closes the electric control valves 5 of the non-energy-consuming temperature control area 23, which not only meets the adjustment of the overall energy-consuming area at the same time, but also reduces the energy waste in the non-energy-consuming area.

[0075] Preset a method for adjusting the energy consumption of the temperature control area of the regional heating and cooling system in the host computer system; the adjustment method is the temperature difference adjustment method. According to the energy consumption characteristics of the regional heating and cooling system 2, the temperature difference adjustment method provides a forced energy consumption adjustment method with large flow and small temperature difference, which further reduces the power consumption of the circulation pump 15 during the energy consumption process.

[0076] Specifically, when the buildings 1-n in the system temperature control area 23 consume energy, set the temperature difference value between the first temperature sensor 7 and the second temperature sensor 7' in the temperature control area in the host computer 18. The host computer 18 uses the data transmission device 22 to send adjustment instructions to the terminal PLC controller 12 through the serial port server 17. The terminal PLC controller 12 receives the adjustment instructions and adjusts the opening degree of the electric control valve 5 to increase / decrease the distribution flow of the system return pipe 4, and increase / decrease the temperature difference value between the first temperature sensor 7 and the second temperature sensor 7'.

[0077] The present invention sets up an automatic heat management system 1, a regional cooling and heating system 2, etc. When the energy load required by the temperature control area is different, the upper computer temperature preset algorithm and adjustment measures can be used to achieve local area temperature adjustment, especially in the cooling mode, the temperature and humidity dual adjustment of the temperature control area can be achieved through this adjustment measure. When the temperature control area uses energy in different time periods, or when the temperature control area has energy-using and non-energy-using areas in the same time period, the temperature control area can be automatically managed by timing adjustment or zoning adjustment; in addition, the temperature difference adjustment method set according to the energy characteristics provides a large flow and small temperature difference forced energy adjustment measure, which further reduces the energy consumption of each link in the energy use process and gives full play to the maximum advantage of passive energy regulation of the regional cooling / heating system.

[0091] By arranging structures such as the T-shaped frame 52 and the L-shaped support rod 32, the length of the L-shaped support rod 32 extending out of the bottom of the T-shaped frame 52 can be adjusted, thereby changing the spacing between the upper and lower C-shaped frames 37 to adapt to the spacing between the hot and cold water supply pipe 3 and the hot and cold water return pipe 4 of the regional heating and cooling system, improving the flexibility of installation.

[0092] For the convenience of sliding adjustment; as Figure 5 、 Figure 6 shown, arc-shaped sliding grooves are provided on the outer walls of both sides of the hot and cold water supply pipe 3 and the hot and cold water return pipe 4 of the regional heating and cooling system, spherical cavities are opened on the inner walls of both sides of the C-shaped frame 37, and rolling balls 38 are movably installed in the spherical cavities, and the rolling balls 38 are in rolling connection with the arc-shaped sliding grooves;

[0093] By arranging the arc-shaped sliding grooves and the rolling balls 38, it is convenient to slide the mounting frame assembly along the hot and cold water supply pipe 3 and the hot and cold water return pipe 4 of the regional heating and cooling system, so as to achieve the purpose of adjusting the position of the fan 30, improving the practicability.

[0094] In this embodiment, when heating is required, the cold and heat source host 16 is used to introduce hot water into the hot and cold water supply pipe 3 and the hot and cold water return pipe 4 of the regional heating and cooling system. The temperatures of the hot and cold water supply pipe 3 and the hot and cold water return pipe 4 are in a high temperature state, and the heating effect is achieved by using their radiation. Since a heat transfer device is installed on the circulating pipeline mechanism, the heat transfer device works to improve the heat transfer efficiency between the hot and cold water supply pipe 3, the hot and cold water return pipe 4 and the region;

[0095] When cooling is required, the cold and heat source host 16 is used to introduce cold water into the water supply pipe 3 and the return water pipe 4 of the district cooling and heating system. The temperatures of the water supply pipe 3 and the return water pipe 4 of the district cooling and heating system are in a low-temperature state. Since a heat transfer device is installed on the circulating pipeline mechanism, the heat transfer device works to improve the heat transfer efficiency between the water supply pipe 3 and the return water pipe 4 of the district cooling and heating system and the area, achieving the effect of cooling the area.

[0096] Embodiment 4:

[0097] A district cooling and heating system for automatic heat management in a temperature-controlled area, as Figures 1-9 shown. For the convenience of temperature control, the following improvements are made on the basis of Embodiment 3: A wind converging mechanism is installed on the side of the water supply pipe 3 and the return water pipe 4 of the district cooling and heating system away from the fan 30. The wind converging mechanism includes:

[0098] A support frame assembly, and both ends of the support frame assembly are detachably installed on two C-shaped frames 37 through plug-in frames 25;

[0099] A first annular frame 29, the first annular frame 29 is adjustably installed on the support frame assembly, and one inner wall of the first annular frame 29 is threadedly connected with a third fixing knob 50, and the third fixing knob 50 is used to fix the first annular frame 29 on the support frame assembly;

[0100] A converging cover 28, the converging cover 28 has a funnel-shaped structure, the converging cover 28 is adhered to one outer wall of the first annular frame 29, and the position of the converging cover 28 is adapted to the fan 30;

[0101] A second annular frame 48, the second annular frame 48 is adhered to the other outer wall of the converging cover 28;

[0102] By setting the wind converging mechanism, the airflow output by the fan 30 can be converged, so as to facilitate directional transmission and improve the transmission distance, meeting different usage requirements.

[0103] In order to adapt to the distance between the water supply pipe 3 and the return water pipe 4 of the district cooling and heating system; as Figure 5 、 Figure 6 shown, the support frame assembly includes:

[0104] L-shaped brackets 33, and two L-shaped brackets 33 are respectively fixed on one outer wall of two plug-in frames 25;

[0105] A first fixing knob 36, and both ends of the first fixing knob 36 are slidably connected to the inner walls of one ends of the two L-shaped brackets 33;

[0106] The second fixing knob 35 is threadedly connected to the inner wall of one side of the L-shaped bracket 33 and is used to fix the first fixing knob 36;

[0107] By providing the support frame assembly, the effective length of the support frame assembly can be adjusted through the L-shaped bracket 33 and the first fixing knob 36, so as to better adapt to the distance between the supply water pipe 3 of the regional heating and cooling system and the return water pipe 4 of the regional heating and cooling system, improving the flexibility of installation.

[0108] For the convenience of fixing the plugboard rack 25; as Figures 5-7 shown, uniformly distributed first teeth 26 are integrally provided on the outer walls on both sides of the plugboard rack 25. Side brackets 39 are integrally provided on the outer walls on both sides of the C-shaped bracket 37. The plugboard rack 25 is inserted into the gap between the side brackets 39 and the C-shaped bracket 37. A cardholder 40 is slidably connected to the inner wall of the side bracket 39. The cardholder 40 is mounted on the side bracket 39 through a spring 42. A pull ring 41 is fixed to the outer wall of one side of the cardholder 40 by a screw. Second teeth adapted to the first teeth 26 are integrally provided on the outer wall of the other side of the cardholder 40; the second teeth are kept engaged with the first teeth 26 under the elastic force of the spring 42;

[0109] By providing structures such as the first teeth 26 and the cardholder 40, when the plugboard rack 25 is inserted into the gap between the side brackets 39 and the C-shaped bracket 37, the second teeth can be kept engaged with the first teeth 26 under the elastic force of the spring 42, so as to achieve the purpose of fixing the plugboard rack 25 and improve the reliability.

[0110] For the convenience of strengthening the C-shaped bracket 37; as Figure 7 shown, an arc-shaped rubber pad 24 is bonded in the arc-shaped chute of the supply water pipe 3 of the regional heating and cooling system. A rolling ball 38 rolls on the arc-shaped rubber pad 24. The gap between the side bracket 39 and the C-shaped bracket 37 is communicated with the ball cavity. One side of the rolling ball 38 away from the arc-shaped rubber pad 24 extends out of the ball cavity and is exposed in the gap between the side bracket 39 and the C-shaped bracket 37; the exposed position of the rolling ball 38 is adapted to the position of the plugboard rack 25;

[0111] Among them, there should be a certain redundancy in the spherical cavity, which can enable the rolling ball 38 to float up and down to a certain extent. By setting structures such as the arc-shaped rubber pad 24, when the plug-in plate frame 25 is inserted into the gap between the side bracket 39 and the C-shaped frame 37, the rolling ball 38 can be squeezed towards the arc-shaped rubber pad 24 side, prompting the arc-shaped rubber pad 24 to deform, thereby increasing the friction between the rolling ball 38 and the arc-shaped rubber pad 24. In addition, preferably, the contact surface between the plug-in plate frame 25 and the rolling ball 38 is set as an anti-slip surface. Based on the pressure, the friction between the rolling ball 38 and the arc-shaped rubber pad 24 increases, avoiding the C-shaped frame 37 from sliding on the water supply pipe 3 of the regional cooling and heating system, thus improving the stability of the fan 30. When it is necessary to adjust the position of the fan 30, only the plug-in plate frame 25 needs to be removed to relieve the pressure on the rolling ball 38, thereby reducing the friction, and then the positions of the C-shaped frame 37 and the fan 30 can be conveniently adjusted, improving the practicality.

[0112] To facilitate the adjustment of the air flow output angle; as Figure 4 、 Figure 8 、 Figure 9 shown, a wind guiding mechanism is detachably installed on one side of the second annular frame 48. The wind guiding mechanism includes:

[0113] A first fixing ring 46, which is detachably installed on the outer wall of one side of the second annular frame 48. A uniformly distributed first plug-in frame 34 is installed on the circumferential outer wall of the first fixing ring 46;

[0114] An angle corrugated tube 27, one end of which is bonded to the outer wall of one side of the first fixing ring 46;

[0115] A second fixing ring 44, the outer wall of one side of which is bonded to the other end of the angle corrugated tube 27. A second plug-in frame 45 adapted to the position of the first plug-in frame 34 is fixed on the circumferential outer wall of the second fixing ring 44;

[0116] A guiding sleeve 49, which is installed on the outer wall of one side of the first plug-in frame 34 close to the second plug-in frame 45. The bending angles of the guiding sleeves 49 installed on different first plug-in frames 34 are different;

[0117] A guiding rod 43, which is slidably installed in the second plug-in frame 45 and the guiding sleeve 49;

[0118] By setting the guiding rod 43, the angle corrugated tube 27 and the guiding sleeves 49 with different bending angles, the corresponding guiding sleeve 49 can be selected, and one end of the guiding rod 43 is passed through the second plug-in frame 45 and then installed in the guiding sleeve 49. Thus, under the support of the guiding rod 43, the angle corrugated tube 27 deforms, making the angle of the angle corrugated tube 27 adapt to the guiding sleeve 49, so as to achieve the purpose of adjusting the air flow output angle and improve the practicality.

[0119] For easy disassembly, adjustment, such as Figure 8 , Figure 9 As shown, on one outer wall of the second annular frame 48, uniformly circumferentially distributed slots 51 are provided. On one outer wall of the first fixing ring 46 close to the second annular frame 48, a plug 47 adapted to the slots 51 is integrally provided. The first fixing ring 46 is detachably inserted into the slots 51 through the plugs 47;

[0120] By providing the plugs 47 and the slots 51, disassembly and assembly can be facilitated. When adjustment is required, rotate the first fixing ring 46 and insert the plugs 47 into different slots 51, so as to change the positions of the respective guide sleeves 49 and improve the adjustment flexibility.

[0121] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
