Description

Dual heat source equipment and its heating control method and heating control device

[0001] This disclosure claims priority to Chinese Patent Application No. 202411532240.6, filed with the Chinese Patent Office on October 30, 2024, entitled "Dual Heat Source Equipment and Heating Control Method and Heating Control Device Thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of heating technology, and more specifically, to a dual heat source device and its heating control method and device. Background Technology

[0003] Dual heat source equipment, also known as "dual fuel heat controller" or "hybrid heating controller", is a device that integrates an air source heat pump and a natural gas furnace, and can switch between furnace heating and heat pump heating.

[0004] Currently, most dual-heat-source heating systems require users to manually switch heating modes according to their needs. For example, if a user feels that the heat pump is not providing enough warmth while using heat pump heating, they can manually switch to boiler heating.

[0005] The above-mentioned solutions require users to manually switch heating modes, which is not intelligent enough and will lead to a poor user experience. Furthermore, users have to manually switch heating modes based on their own feelings of hot and cold, which cannot maximize energy utilization, easily leads to energy waste and high energy consumption, and makes the cost of heat sources uncontrollable. In addition, if a large number of gas furnaces are used for heating, it may lead to excessive greenhouse gas emissions from the combustion of natural gas.

[0006] There is currently no effective solution to the problem that dual-heat-source devices require users to manually switch heating modes, resulting in high energy consumption and a poor user experience. Summary of the Invention

[0018] In some implementations, during heat pump heating, the switching of heating modes is controlled based on the heat pump's operating status, including:

[0019] Determine whether the system will shut down at a specific temperature point within a preset time after the heat pump starts supplying heat;

[0020] If so, continue using the heat pump for heating;

[0021] If not, switch to boiler heating.

[0022] In some implementations, after continuing to use the heat pump for heating, the following is also included:

[0023] When a change in outdoor temperature is detected, return to the step of determining whether the current outdoor temperature is less than or equal to the preset temperature.

[0024] In some implementations, during boiler heating, the switching of heating modes is controlled based on boiler operating time and outdoor temperature, including:

[0025] During the period of boiler heating, the actual running time of boiler heating is recorded;

[0026] When the actual operating time of the boiler heating reaches the minimum operating time of the boiler, determine whether the current outdoor temperature is greater than or equal to the preset temperature + N.

[0027] If the current outdoor temperature is greater than or equal to the preset temperature + N, then switch to heat pump heating;

[0028] If the current outdoor temperature is less than the preset temperature + N, then return to the step of determining whether the current outdoor temperature is less than or equal to the preset temperature, where N > 0.

[0029] This disclosure also provides a heating control device for a dual-heat-source device, wherein the heating method of the dual-heat-source device includes heat pump heating and furnace heating, and the device includes:

Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0051] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0052] Example 1

[0053] The dual-heat-source device involved in this embodiment integrates an air-source heat pump and a natural gas boiler. Heating can be provided through either the air-source heat pump or the natural gas boiler; that is, the heating methods of the dual-heat-source device include heat pump heating and boiler heating. In practical use, users can choose to manually switch the heating mode or enable the automatic heat source switching function, which uses the heating control method of this embodiment to automatically switch the heating mode.

[0054] This embodiment provides a heating control method for a dual heat source device. Figure 1 is a flowchart of the heating control method for a dual heat source device provided in this embodiment. As shown in Figure 1, the method includes the following steps:

[0055] S101, determine whether the current outdoor temperature is less than or equal to the preset temperature.

[0056] S102, If the current outdoor temperature is less than or equal to the preset temperature, use a gas-fired boiler for heating.

[0057] S103 If the current outdoor temperature is higher than the preset temperature, determine the heating method to be used based on the current gas cost and electricity cost.

[0058] S104, during heat pump heating, controls the switching of heating modes according to the operation of the heat pump.

[0059] S105 controls the switching of heating modes based on the boiler's operating time and outdoor temperature during boiler heating.

[0060] The preset temperature can be set according to the climate conditions of the location of the dual heat source equipment or the actual needs of the user. For example, it can be set by the staff when installing the dual heat source equipment, and / or by the user when using the dual heat source equipment.

[0061] Furnace heating uses natural gas to provide warmth, while heat pump heating uses the heat generated by the operation of a compressor. In the same amount of time, furnace heating will raise the indoor temperature faster than heat pump heating.

[0062] If the current outdoor temperature is less than or equal to the preset temperature, it means that the current outdoor temperature is low. In this case, the boiler heating will be used first to ensure that the indoor temperature quickly reaches the target temperature set by the user, so that the user can quickly feel the temperature comfort.

[0063] If the current outdoor temperature is higher than the preset temperature, the more cost-effective heating method will be determined based on the current gas and electricity costs, and this method will be used to reduce heating costs and energy consumption.

[0064] During heat pump heating, the switching of heating modes is controlled based on the operation of the heat pump. Similarly, during gas boiler heating, the switching of heating modes is controlled based on the operating time of the gas boiler and the outdoor temperature. This allows for a more accurate grasp of the timing of switching heating modes based on the actual operating conditions of the equipment, maximizing energy utilization while meeting the heating needs of users.

[0065] This embodiment targets a dual-heat-source device. It controls and switches heating modes based on outdoor temperature, gas costs, electricity costs, and the actual operating conditions of the equipment. When the current outdoor temperature is less than or equal to a preset temperature, it prioritizes boiler heating to ensure rapid fulfillment of user heating needs. When the current outdoor temperature is greater than the preset temperature, it determines the more cost-effective heating mode based on current gas and electricity costs, thus reducing heating costs and energy consumption. Furthermore, it controls the switching of heating modes based on the actual operating conditions of the equipment during heat pump and boiler heating periods, accurately determining the timing of mode switching to maximize energy utilization while meeting user heating needs. Users do not need to manually switch heating modes; the system automatically and intelligently switches to the most cost-effective and efficient mode, reducing energy loss and avoiding excessive greenhouse gas emissions due to overuse of boiler heating. This improves user experience and solves the problem of high energy consumption and poor user experience caused by manual switching of heating modes in related technologies.

[0066] In one implementation, determining the required heating method based on current gas and electricity costs includes: calculating current gas and electricity costs; if current gas costs are greater than or equal to current electricity costs, using a heat pump for heating; if current gas costs are less than current electricity costs, using a boiler for heating.

[0067] This implementation method automatically selects a lower-cost heating method when the current outdoor temperature is higher than the preset temperature, thereby reducing heating costs and energy consumption.

[0068] Specifically, the current gas cost can be calculated by comparing the current gas price per unit area with the boiler efficiency. This gas cost represents the cost per cubic meter (m³) of natural gas produced by the boiler. 3 The actual gas cost required. Specifically, the current electricity price can be calculated by comparing the current electricity price per unit with the heat pump's heating efficiency. This electricity cost represents the actual electricity cost required per kilowatt-hour (kWh) of the air source heat pump. Considering both furnace efficiency and heat pump heating efficiency in calculating the actual gas cost ensures a more reliable comparison between gas and electricity costs, which is beneficial for energy-saving control of dual-heat-source equipment.

[0069] Considering that the units of gas price and electricity price may be different, it is necessary to convert the units. When the units of gas cost and electricity cost are consistent, the two are compared to ensure their comparability.

[0070] Users can input the unit price of gas and electricity through the thermostat. Specifically, users can input the electricity price for different times of weekdays and holidays in different seasons, such as the electricity price for different times of weekdays in summer or winter, and the electricity price for different times of weekends and holidays in summer or winter.

[0071] Furnace efficiency is the energy conversion efficiency of the natural gas furnace itself. Users can obtain it from the equipment nameplate or instruction manual and input it through the temperature controller. Alternatively, the furnace efficiency can be stored in the temperature controller when the equipment leaves the factory, and the stored furnace efficiency can be automatically read when gas costs need to be calculated.

[0072] The heat pump heating efficiency (COP) is the ratio of heat generated to electrical energy consumed during the heating process of an air source heat pump. It can pre-store the COP corresponding to different outdoor temperatures and power inputs, and automatically retrieve the COP corresponding to the current outdoor temperature when electricity costs need to be calculated.

[0073] During heat pump heating, the switching of heating mode is controlled according to the operation of the heat pump, including: determining whether a temperature point shutdown occurs within a preset time after entering heat pump heating; if so, heat pump heating continues; if not, switching to boiler heating.

[0074] The preset time can be the factory default value or set by the user. Temperature point shutdown means that the heat pump stops running when the indoor temperature reaches a certain temperature point, which can be greater than or equal to the target temperature set by the user.

[0075] If the system shuts down at a certain temperature point within the preset time after entering heat pump heating mode, it means that the heat pump is providing sufficient heat to meet the user's heating needs, and heat pump heating can continue to be used. If the system does not shut down at a certain temperature point within the preset time after entering heat pump heating mode, it means that the heat pump is providing insufficient heat and the current indoor temperature is still low. In this case, it is advisable to switch to boiler heating to improve the indoor temperature rise rate.

[0076] In this embodiment, when heat pump heating is used for cost considerations, the heating mode is switched within a preset time after the heat pump heating is turned on, depending on whether the temperature point is reached and the system shuts down. This ensures that the indoor temperature quickly reaches the user's target temperature, thereby quickly meeting the user's heating needs, while also taking energy conservation into account.

[0077] In some embodiments, after continuing to use the heat pump for heating, the method further includes: when a change in outdoor temperature is detected, returning to step S101 to determine whether the current outdoor temperature is less than or equal to a preset temperature. This embodiment allows for timely re-judgment and switching if the outdoor temperature changes during heat pump heating, thereby promptly switching to the optimal heating mode.

[0078] During boiler heating, the heating mode is switched according to the boiler running time and outdoor temperature, including: recording the actual running time of boiler heating during boiler heating; when the actual running time of boiler heating reaches the minimum running time of boiler, determining whether the current outdoor temperature is greater than or equal to the preset temperature + N; if the current outdoor temperature is greater than or equal to the preset temperature + N, then switching to heat pump heating; if the current outdoor temperature is less than the preset temperature + N, then returning to the step S101 of determining whether the current outdoor temperature is less than or equal to the preset temperature.

[0079] The minimum operating time of the gas-fired boiler can be the factory default value or set by the user. N > 0, preferably N = 2. Users can adjust the value of N according to their heating comfort to obtain the best heating experience from the gas-fired boiler.

[0080] In this implementation, when the boiler heating is automatically selected based on heating speed or cost, the boiler heating is ensured to run continuously for a certain period of time during the boiler heating period to avoid frequent switching of heating modes and affecting the user experience. After the boiler heating has been running continuously for a certain period of time, the indoor temperature has been raised to a certain extent. If the outdoor temperature is greater than or equal to the preset temperature + N, it means that the outdoor temperature is not very low. In this case, the system can switch to heat pump heating to allow the indoor temperature to rise slowly, taking into account both energy saving and user comfort.

[0081] Considering that the simultaneous operation of two heat sources would result in higher energy consumption, only one heat source is used for heating at a time in this embodiment of the disclosure.

[0082] Example 2

[0083] This embodiment illustrates the heating control method of the aforementioned dual-heat-source device with a specific example. However, it is worth noting that this specific example is only for better illustration of this disclosure and does not constitute an undue limitation of this disclosure. The same or corresponding terminology as in the above embodiments will not be repeated in this embodiment.

[0084] The dual-heat-source system includes a thermostat, which displays the operating status of both the heat pump and the boiler, and allows users to input and set desired parameters, such as the target heating temperature. The thermostat defaults to using the heat pump for heating.

[0085] Figure 2 shows a schematic diagram of the heating control process, which includes the following steps:

[0086] S201, users input the electricity price CER ($ / kWh) for different time periods in summer and winter via the thermostat, for example, the peak and off-peak electricity prices for weekdays and weekends in summer and winter. Users input the gas price UEGR ($ / m³) via the thermostat. 3The temperature and furnace efficiency (GFE) are set by the user via the thermostat. The preset temperature T0, preset time t0, and minimum furnace operating time t1 are also set.

[0087] S202, Detect the current outdoor temperature T 外 And determine whether T is satisfied. 外 If ≤T0, proceed to S206; otherwise, proceed to S203.

[0088] S203, the thermostat obtains the current electricity price (CER) and COP, and calculates the current electricity cost S1 = CER / COP. The thermostat calculates the current gas cost S2 = UEGR / (GFE / 100) / LNG, where LNG (kWh / m³) is the gas cost. 3 This indicates the local conversion rules for natural gas kilowatt-hours to cubic meters, linking natural gas kilowatt-hours and cubic meters to facilitate the calculation of gas cost S2, and ensuring that the units of gas cost and electricity cost are consistent for easy comparison.

[0089] Determine if S2≥S1 is satisfied. If yes, proceed to S204; otherwise, proceed to S206.

[0090] S204 is used for heat pump heating.

[0091] S205, determine whether a temperature point shutdown occurs within the t0 time period of entering heat pump heating. If yes, proceed to S204 to continue heat pump heating; otherwise, proceed to S206 to switch to boiler heating.

[0092] S206, for boiler heating.

[0093] S207, During the boiler heating period, after the actual boiler heating operation time reaches t1, determine whether the time T is satisfied. 外 If the value is ≥T0+N, proceed to S204 to switch to heat pump heating; otherwise, return to S202 to re-evaluate.

[0094] This embodiment targets a dual-heat-source system, enabling automatic and intelligent switching between heat pump heating and boiler heating without manual intervention by the user, thus improving the user experience. It controls and switches heating modes based on outdoor temperature, gas costs, electricity costs, and actual equipment operating conditions. When the current outdoor temperature is less than or equal to a preset temperature, boiler heating is prioritized to quickly meet the user's heating needs. When the current outdoor temperature is greater than the preset temperature, the more cost-effective heating mode is determined based on current gas and electricity costs, thus reducing heating costs and energy consumption. Furthermore, by controlling the switching of heating modes according to the actual equipment operating conditions during both heat pump and boiler heating periods, the system can accurately determine the timing of heating mode switching, maximizing energy utilization while meeting the user's heating needs. This embodiment automatically and intelligently switches to the heating mode with the best cost and heating efficiency, reducing energy consumption, avoiding excessive greenhouse gas emissions due to overuse of gas-fired heating, improving user experience, and solving the problem of high energy consumption and poor user experience caused by users having to manually switch heating modes in dual heat source equipment in related technologies. It effectively provides the best heating mode to meet the growing demand.
