Description

Technical Field

[0001] This application relates to the field of energy-saving technology, specifically to a temperature control system. Background Technology

[0002] Since the Industrial Revolution, the Earth's natural ecological balance has been impacted like never before, with the carbon cycle system bearing the brunt. The balance between carbon sources and sinks has been disrupted, leading to the continuous accumulation of carbon in the atmosphere and prompting global reflection and attention to consequences such as global warming and rising sea levels. Human survival depends on energy and resources, which are provided by nature. How to utilize them effectively and create a harmonious living environment is an extremely important issue that deserves the joint consideration of all humankind.

[0003] Energy production and related consumption activities are the main sources of carbon dioxide emissions. Vigorously promoting carbon emission reduction in the energy sector is an important measure to achieve carbon peaking and carbon neutrality, as well as to accelerate the construction of a modern energy system.

[0004] Therefore, we should vigorously promote efficient and energy-saving technologies, support energy-saving renovation and upgrading in traditional sectors, advance the formulation and revision of energy-saving standards, promote the implementation of electricity substitution according to local conditions, vigorously promote the replacement of coal and oil with electricity, orderly promote the conversion of electricity to gas, and improve the electrification level of end-use energy. Related experts have repeatedly pointed out that the main manifestation of zero-carbon energy is the direct output of electricity. Replacing fossil fuels with electricity and producing heat through efficient conversion is a necessity for the energy revolution.

[0005] However, existing heat pump units with temperature control systems have low overall energy efficiency and high operating costs when used in extremely cold regions. The waste energy generated cannot be recycled, resulting in a huge waste of energy. Therefore, in order to further achieve the goal of energy conservation and emission reduction, it is necessary to further optimize the relevant energy-consuming equipment, improve its energy utilization rate and operating economy, so as to achieve green, environmentally friendly and energy-saving technical effects. Summary of the Invention

[0006] To address the issues of low energy efficiency and high operating costs in existing temperature control systems, this application provides a temperature control system that can efficiently convert and utilize energy from nature and effectively reuse the waste energy generated by the system itself, thereby improving the overall energy efficiency, operational stability, and economy of the system and reducing the impact of traditional temperature control systems on the ecological environment.

[0021] K2. When the system requires the fourth heat exchange mechanism to provide cooling capacity, and the temperature of the first tank and the second tank is higher than the set temperature, the circuit between the first coil, the second coil and the corresponding tank through the medium to achieve heat exchange is closed, and cooling capacity is provided through the third heat exchange mechanism.

[0022] K3. When the system requires the fourth heat exchange mechanism to provide heat, and the temperature of the second tank is higher than the set temperature, the circuit of heat exchange between the second coil and the second tank through the medium is started.

[0023] K4. When the system requires the fourth heat exchange mechanism to provide heat, and the temperature of the second tank is lower than the set temperature, the circuit between the second coil and the second tank through the medium to achieve heat exchange is closed, and heat is provided through the third heat exchange mechanism.

[0024] K5. When the system needs to defrost the third heat exchange mechanism, start the circuit for heat exchange between the first coil and the first tank through the medium.

[0025] In one specific implementation scheme, in the control method K2, the tank heat exchange device is started to cool the second tank and heat the first tank. When the temperature of the second tank is not higher than the set temperature, the loop of the second coil and the second tank to exchange heat through the medium is started.

[0026] In one specific implementation scheme, in the control method K4, the heater of the second tank is started and running.

Detailed Implementation

[0037] This application provides a temperature control system that addresses the problems of low energy efficiency and high operating costs in existing temperature control systems. The overall approach is as follows:

[0038] Please see Figure 1 , Figure 2This application provides a temperature control system, including a first heat exchange mechanism 1, a second heat exchange mechanism 2, a third heat exchange mechanism 4, a fourth heat exchange mechanism 6, a reversing mechanism 3, an adjusting mechanism, a photovoltaic mechanism 7, and a control mechanism 8. The first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 4, and the fourth heat exchanger 6 respectively achieve energy transfer through heat exchange of the medium; the reversing mechanism 3 controls the flow direction of the medium to realize the corresponding heat exchange circuit. The reversing mechanism 3 is fluidly connected to the first heat exchanger 1 and the second heat exchanger 2 respectively, so that the medium from the first heat exchanger 1 can be transported through the second heat exchanger 2 and then flow back; the reversing mechanism 3 is fluidly connected to the third heat exchanger 4 and the fourth heat exchanger 6 respectively, so that the medium flowing back from the second heat exchanger 2 can be transported to it; the third heat exchanger 4 and the fourth heat exchanger 6 are fluidly connected to the first heat exchanger 1 respectively, so that the medium from the reversing mechanism 3 can be transported to the first heat exchanger 1; the regulating mechanism is set in the fluid channel between the reversing mechanism 3 and the third heat exchanger 4 and the fourth heat exchanger 6 to the first heat exchanger 1, so as to control the medium flow in the corresponding fluid channel; the photovoltaic mechanism 7 obtains light energy and is electrically connected to the fourth heat exchanger 6 to provide energy; the control mechanism 8 monitors and controls the working status of the relevant units of the system to realize the corresponding energy transfer mode. This temperature control system improves overall system energy efficiency, reduces energy consumption and operating costs, and effectively utilizes traditionally waste energy. It achieves different energy source supply modes according to different system operating modes, ensuring system reliability and stability, providing a more energy-efficient and high-performance energy source, and eliminating pollutant emissions, making it green and environmentally friendly.

[0039] Please see Figure 2In this embodiment, the fourth heat exchange mechanism 6 includes at least a first tank 601 with a built-in first coil 602 and a second tank 604 with a built-in second coil 605. The first coil 602 and the second coil 605 are respectively in fluid communication with the reversing mechanism 3 and the first heat exchange mechanism 1 to achieve medium flow and heat exchange with the corresponding tanks. Correspondingly, the regulating mechanism includes at least a first regulating element 51 for controlling the medium flow of the first coil 602 and a second regulating element 52 for controlling the medium flow of the second coil 605. The regulating mechanism also includes a third regulating element 53 for controlling the medium flow of the third heat exchange mechanism 4, thereby realizing different heat exchange circuits. In this example, the first tank 601 and the second tank 604 are equipped with heaters to provide heat energy to the corresponding tanks, meeting the heat requirements of the first tank 601 and the second tank 604 under the corresponding energy supply modes. The fourth heat exchange mechanism 6 is also equipped with a tank heat exchange device 603 to realize heat exchange between the first tank 601 and the second tank 604. The tank heat exchange device 603 includes a heating end and a cooling end. The heating end is located in the first tank 601 and the cooling end is located in the second tank 604, so that the structure of the fourth heat exchange mechanism 6 is more compact and the heat exchange efficiency is higher, meeting the temperature requirements of the first tank 601 and the second tank 604 under the corresponding energy supply mode.

[0040] Furthermore, the control mechanism 8 in this embodiment implements the following control methods: K1, when the system requires the fourth heat exchange mechanism 6 to provide cooling capacity, and the temperature of the first tank 601 and / or the second tank 604 is lower than the set temperature, the circuit for heat exchange between the corresponding tank and the corresponding coil that is lower than the set temperature is activated through the medium; K2, when the system requires the fourth heat exchange mechanism 6 to provide cooling capacity, and the temperature of the first tank 601 and the second tank 604 is higher than the set temperature, the circuit for heat exchange between the first coil 602, the second coil 605 and the corresponding tank through the medium is closed, and cooling capacity is provided through the third heat exchange mechanism 4; K3. When the system requires heat from the fourth heat exchange mechanism 6 and the temperature of the second tank 604 is higher than the set temperature, the circuit for heat exchange between the second coil 605 and the second tank 604 through the medium is activated. K4. When the system requires heat from the fourth heat exchange mechanism 6 and the temperature of the second tank 604 is lower than the set temperature, the circuit for heat exchange between the second coil 605 and the second tank 604 through the medium is closed, and heat is provided through the third heat exchange mechanism 4. K5. When the system needs to defrost the third heat exchange mechanism 4, the circuit for heat exchange between the first coil 602 and the first tank 601 through the medium is activated.

[0041] It should be noted that in control mode K2, the tank heat exchange device 603 can be started to cool the second tank 604 and heat the first tank 601. When the temperature of the second tank 604 is not higher than the set temperature, the circuit for heat exchange between the second coil 605 and the second tank 604 through the medium is activated. In control mode K4, the heater of the second tank 604 can be started, and when the temperature of the second tank 604 is not lower than the set temperature, the circuit for heat exchange between the second coil 605 and the second tank 604 through the medium is activated.

[0042] Specifically, please refer to the following during use: Figure 1 The first heat exchange mechanism 1 can be a heating and cooling air conditioning mechanism; the second heat exchange mechanism 2 can be a jet enthalpy-increasing variable frequency heat pump mechanism; the reversing mechanism 3 can be a four-way valve; the third heat exchange mechanism 4 can be a variable frequency evaporative heat dissipation mechanism; the regulating mechanism can be a two-way regulating component; the fourth heat exchange mechanism 6 can be a supplementary energy-increasing enthalpy-increasing condensing evaporation mechanism; the photovoltaic mechanism 7 converts solar energy into electrical energy; and the control mechanism 8 communicates with each relevant unit of the system to realize intelligent energy supply.

[0043] In this specific application example, the fluid outlet of the second heat exchanger 2 is connected to the inlet of the reversing mechanism 3. The outlet of the reversing mechanism 3 is connected to the inlets of the fourth heat exchanger 6 and the third heat exchanger 4 via an adjusting mechanism. The outlet of the fourth heat exchanger 6 is connected to the inlet of the first heat exchanger 1, and the outlet of the first heat exchanger 1 is connected to the return inlet of the reversing mechanism 3. The return outlet of the reversing mechanism 3 is connected to the inlet of the second heat exchanger 2 via a gas-liquid separator, forming a system pipeline loop. The photovoltaic mechanism 7 is connected in parallel with the fourth heat exchanger 6 and the user's mains power line via the control mechanism 8. The control mechanism 8 is connected to the control circuits of the relevant units within the system to control each mechanism to complete the corresponding actions.

[0044] The fourth heat exchange mechanism 6 also includes two multi-energy source storage tanks, namely the first tank 601 and the second tank 604. The two tanks are interconnected and arranged vertically, and are connected by a thermoelectric refrigeration mechanism, namely a tank heat exchange device 603. The heating end and the cooling end of the tank heat exchange device 603 extend into the first tank 601 and the second tank 604 respectively, forming an integral part with the corresponding tanks. The first tank 601 and the second tank 604 are respectively equipped with a first coil 602 for heat exchange. The second coil 605 exchanges hot and cold energy with the corresponding tank; the low-pressure DC heater, namely the first heater 606 installed in the first tank 601 and the second heater 607 installed in the second tank 604 in this example, can provide heat energy to the corresponding tanks respectively; therefore, the first tank 601, the second tank 604, the first coil 602 and the second coil 605 for heat exchange, the tank heat exchange device 603, and the heater constitute the fourth heat exchange mechanism 6 with three energy sources.

[0045] Temperature sensors are installed inside the first tank 601 and the second tank 604. When the system requires cooling from the fourth heat exchange mechanism 6, and the temperature inside the first tank 601 and the second tank 604 is lower than the system set temperature, the first tank 601 exchanges heat with the first coil 602, or the second tank 604 exchanges heat with the second coil 605, through the corresponding medium to meet the system's operating requirements. When the temperature inside the first tank 601 and the second tank 604 is higher than the set temperature and also higher than the ambient temperature, the first tank 601 exchanges heat with the first coil 602... Alternatively, the second tank 604 and the second coil 605 may stop exchanging heat, and the system may switch to the third heat exchange mechanism 4 to provide cooling capacity under the control of the third regulating component 53 of the regulating mechanism to meet the system operation requirements; at the same time, the tank heat exchange device 603 is continuously powered on to cool the second tank 604, and the first tank 601 is also heated to store low-temperature cold energy for the system; when the temperature of the second tank 604 drops to the set value and is lower than the ambient temperature, the regulating mechanism switches back to the heat exchange loop through which the second coil 605 and the second tank 604 exchange heat, and transfers cooling capacity to the building.

[0046] When the system requires heat from the fourth heat exchange mechanism 6, the first tank 601 can remain independent of the heat pump system in this mode. When the temperature inside the second tank 604 is higher than the system set temperature, the second regulating element 52 of the regulating mechanism connects the heat exchange circuit between the second tank 604 and the second coil 605 to meet system operation requirements. When the temperature inside the second tank 604 is lower than the set temperature and also lower than the water's anti-icing protection temperature, the second regulating element 52 of the regulating mechanism disconnects the heat exchange circuit between the second tank 604 and the second coil 605, and the system is then controlled by the third regulating element 53 of the regulating mechanism to switch to the third heat exchange mechanism. 4. Provide heat to meet system operation requirements; In this mode, the solar photovoltaic mechanism 7 no longer connects to the tank heat exchange device 603, but instead connects to the low-voltage DC heaters, namely the first heater 606 and the second heater 607 in this example, through the control mechanism 8, to heat the first tank 601 and the second tank 604 respectively, storing high-temperature energy for the system; The first tank 601 maintains a constant temperature state, and when the temperature of the second tank 604 rises to the set value and is higher than the anti-icing protection temperature, the second regulating component 52 of the regulating mechanism will reconnect the heat exchange circuit between the second tank 604 and the second coil 605 to transfer heat to the building.

[0047] When entering winter heating mode, the system's reversing mechanism 3 connects the heating circuit, allowing the first heat exchanger 1 to transfer heat energy to the building. The system's regulating mechanism connects the fourth heat exchanger 6, making it the evaporator end of the second heat exchanger 2, providing basic energy for the system. Simultaneously, the photovoltaic mechanism 7 is heated by the control mechanism 8, which connects to the relevant low-voltage DC heater of the fourth heat exchanger 6, providing supplementary basic energy for the system and maintaining the temperature of the first tank 601 of the fourth heat exchanger 6 for hot water supply. When the basic energy provided by the fourth heat exchanger 6 cannot meet the system's heating demand, the control mechanism 8 controls the regulating mechanism to connect part or all of the evaporator end circuits to the third heat exchanger 4, absorbing energy from the air to meet the building's needs.

[0048] When entering summer cooling air conditioning mode, the system's reversing mechanism 3 connects the cooling circuit, allowing the first heat exchanger 1 to transfer cooling capacity to the building. The system's regulating mechanism connects the fourth heat exchanger 6, making it the condenser end of the second heat exchanger 2, providing basic cooling capacity for the system. Simultaneously, the control mechanism 8 connects the photovoltaic mechanism 7 and the thermoelectric cooling mechanism (i.e., the tank heat exchange device 603) in the fourth heat exchanger 6 to heat and cool the corresponding tanks, providing supplementary basic energy to the system and maintaining the temperature of the first tank 601 of the fourth heat exchanger 6 for hot water supply. When the basic energy provided by the fourth heat exchanger 6 cannot meet the system's cooling needs, the control mechanism 8 controls the regulating mechanism to connect part or all of the condenser end circuit to the third heat exchanger 4, releasing energy into the air to meet the building's cooling needs.

[0049] When the system is in heating or cooling mode, and the basic energy provided by the fourth heat exchanger 6 meets the system's cooling or heating requirements, the control mechanism 8 connects the photovoltaic mechanism 7 to the mains power complementary line, and connects the inverter device to supplement the user's power system with "zero-cost" electricity, reducing the user's mains power consumption.

[0050] When the system requires heat from the fourth heat exchanger 6, and the fourth heat exchanger 6 cannot meet the system's heat supply needs, the system switches to the third heat exchanger 4 to provide heat to meet the system's heat requirements. In this state, the third heat exchanger 4 is greatly affected by the ambient temperature and humidity and is prone to frosting. When the system defrosts, the four-way reversing mechanism 3 switches the condensation and evaporation direction to absorb heat from the building to heat the third heat exchanger 4. At this time, the first regulating element 51 of the regulating mechanism connects to the first coil 602 inside the fourth heat exchanger 6. Since the temperature inside the first tank 601 remains constant at a high energy level, it can quickly increase the return gas temperature of the second heat exchanger 2, thereby quickly heating the frosted third heat exchanger 4, accelerating the defrosting rate, reducing the system defrosting time, alleviating the energy fluctuations of the first heat exchanger 1 system, and reducing "ineffective power consumption" to save operating costs.

[0051] In summary, this application presents a temperature control system that can efficiently convert and utilize energy from nature, effectively reuse the waste energy generated by the system itself, reduce system temperature fluctuations, improve the overall energy efficiency, operational stability, and economy of the system, and reduce the impact of traditional temperature control systems on the ecological environment.

[0052] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating this application and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
