[0112] Step S10: Obtain the first parameter of the heat pump system and the second parameter of the heating system. The first parameter and the second parameter both represent the relationship between the heating capacity and operating cost of the corresponding equipment.

[0113] The first parameter represents the relationship between the heat pump system's heating capacity and operating costs.

[0114] The heating capacity of a heat pump system refers to the heat generated within a certain period of time after the convective heat exchange equipment of the heat pump system is turned on. In a heat pump system, the heating capacity represents the heat energy absorbed from the external environment and transferred to the room to heat the indoor space.

[0115] Operating costs refer to the costs incurred by a heat pump system in generating heat energy. These costs can be determined based on electricity prices and the system's power consumption. For example, the operating cost can be calculated by multiplying the electricity price by the system's power consumption. Alternatively, operating costs can be determined based on electricity prices, the system's heating capacity, and its heat pump efficiency. For instance, the operating cost can be calculated as the ratio of the product of the electricity price and the system's heating capacity to its heat pump efficiency. The system's power consumption can be obtained from an electricity meter reading, or it can be the system's average power consumption over a period of time.

[0116] In this embodiment, obtaining the first parameter of the heat pump system can be achieved by: obtaining the heating capacity and operating cost of the heat pump system, and determining the first parameter of the heat pump system based on the heating capacity and operating cost, for example, by determining the first parameter of the heat pump system based on the ratio of the heating capacity to the operating cost. Alternatively, it can be achieved by obtaining the heating capacity and power consumption of the heat pump system, and determining the first parameter of the heat pump system based on the heating capacity, power consumption, and electricity price, for example, by obtaining the product of the power consumption and the electricity price, which is equivalent to the operating cost of the heat pump system, and obtaining the first parameter of the heat pump system based on the heating capacity and the ratio of this product. Alternatively, it can be achieved by obtaining the heating capacity and heat pump efficiency of the heat pump system, and determining the first parameter of the heat pump system based on the heating capacity, heat pump efficiency, and electricity price, for example, by obtaining the product of the electricity price and the heating capacity of the heat pump system, obtaining a first ratio between this product and the heat pump efficiency, and then obtaining the first parameter of the heat pump system based on a second ratio between the heating capacity and the first ratio. Alternatively, obtain the heat pump efficiency and electricity price of the heat pump system, and determine the first parameter of the heat pump system based on the heat pump efficiency and electricity price.

[0117] The second parameter represents the relationship between the heating system's heat output and operating costs.

[0118] The heating capacity of a heating system refers to the heat generated over a period of time after the gas-fired heating equipment in the system is turned on. In a heating system, the heating capacity represents the amount of heat generated by the gas fuel heating the refrigerant, which then provides heat to the indoor space. The heating capacity directly affects the system's heating effect and energy consumption; therefore, it is an important factor to consider when selecting a heat pump system and operating a heating system.

[0119] Operating costs refer to the costs incurred by a heating system in generating heat energy. These costs can be determined based on gas prices and the gas consumption of the heating system's equipment. For example, the operating cost can be calculated by multiplying the gas price by the gas consumption of the heating system's equipment. Alternatively, the operating cost can be determined based on the gas consumption of the heating system's equipment, the heating capacity of the system, and the gas efficiency of the system. For instance, the operating cost can be determined by dividing the product of the electricity price and the heating capacity of the system by the gas efficiency of the system. The gas consumption of the heating system can be obtained by checking the electricity meter, or it can be the average gas consumption of the heating system over a period of time.

[0120] In this embodiment, obtaining the second parameter of the heating system can be achieved by: obtaining the heating capacity and operating cost of the heating system, and determining the second parameter of the heating system based on the heating capacity and operating cost, for example, by determining the second parameter of the heating system based on the ratio of the heating capacity to the operating cost. Alternatively, it can be achieved by obtaining the heating capacity and gas consumption of the heating system, and determining the second parameter of the heating system based on the heating capacity, gas consumption, and gas price, for example, by obtaining the product of the gas consumption and the gas price, which is equivalent to the operating cost of the heating system, and obtaining the second parameter of the heating system based on the ratio of the heating capacity to the product. Alternatively, it can be achieved by obtaining the heating capacity and gas efficiency of the heating system, and determining the second parameter of the heating system based on the heating capacity, gas efficiency, and gas price, for example, by obtaining the product of the gas price and the heating capacity, obtaining a first ratio between the product and the gas efficiency, and then obtaining the second parameter of the heating system based on a second ratio between the heating capacity and the first ratio. Alternatively, obtain the gas efficiency and gas consumption of the heating system, and determine the second parameter of the heating system based on the gas efficiency and gas consumption.

[0121] Step S20: Control the operation of the heat pump system and the heating system according to the first parameter and the second parameter.

[0122] The operation of a heat pump system includes turning it on or off for heating, just as the operation of a heating system includes turning it on or off for heating. Therefore, at least the following scenarios exist: 1. The heat pump system is on for heating, and the heating system is off, meaning all the heat in the indoor space comes from the heat pump system, and all heating costs are incurred when the heat pump system is operating. 2. The heat pump system is off, and the heating system is on for heating, meaning all the heat in the indoor space comes from the heating system, and all heating costs are incurred when the heating system is operating. 3. The heat pump system and the heating system are on simultaneously, meaning all the heat in the indoor space comes from both the heat pump system and the heating system, and all heating costs are incurred when both systems are operating for heating.

[0123] In one feasible implementation, a correspondence between a first parameter, a second parameter, the operating status of the heat pump system, and the operating status of the heating system can be pre-established, and the operating status of the heat pump system and the operating status of the heating system can be obtained based on the first parameter, the second parameter, and the correspondence.

[0124] In another feasible implementation, the magnitudes of the first parameter and the second parameter can be compared, and the operation of the heat pump system and the heating system can be controlled according to the comparison result. For example, when the first parameter is greater than the second parameter, the heat pump system is controlled to operate; when the first parameter is less than the second parameter, the heating system is controlled to operate; and when the first parameter is equal to the second parameter, one or both of the heat pump system and the heating system are controlled to operate simultaneously.

[0125] Because the operating costs of heat pump systems and heating systems differ, and their heating capacity per unit time also differs, the first parameter corresponding to the heat pump system and the second parameter corresponding to the heating system are different. By using the first parameter corresponding to the heat pump system and the second parameter corresponding to the heating system, the heat pump system and the heating system can be reasonably controlled, thereby reducing the heating cost of the entire environmental control system.

[0126] This embodiment provides a control method for an environmental regulation system. By controlling the operation of a heat pump system and a heating system according to a first parameter and a second parameter, where the first parameter represents the relationship between the heating capacity and operating cost of the heat pump system, and the second parameter represents the relationship between the heating capacity and operating cost of the heating system, the two heating resources, the heat pump system and the heating system, are rationally scheduled through the relationship between heating capacity and operating cost, thereby optimizing operating costs. This not only achieves the effect of indoor heating but also reduces energy consumption and heating costs.

[0127] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, the first parameter includes the energy cost ratio of the heat pump system, and the second parameter includes the energy cost ratio of the heating system, as referred to... Figure 4 Step S20 includes steps S21 to S22:

[0128] Step S21: Obtain the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system.

[0129] The energy cost ratio (ECR) of a heat pump system refers to the ratio of its heating capacity to its operating cost. The energy cost ratio of a heating system refers to the ratio of its heating capacity to its operating cost. The difference between the ECR of the heat pump system and the energy cost ratio of the heating system is calculated. When both systems have the same heating capacity, a higher ECR indicates lower operating costs, or vice versa. Therefore, the ECR effectively compares the relationship between the heating capacity and operating costs of heat pump and heating systems, facilitating subsequent operation and control.

[0130] Step S22: Control the operation of the heat pump system and the heating system according to the difference and the preset energy cost ratio.

[0131] The preset energy cost ratio ranges from 0 kWh / yuan to 2.0 kWh / yuan. The preset energy cost ratio can be set at the factory or determined based on the actual operation of the environmental control system, such as the number of currently active indoor units and / or the number of radiant terminal devices.

[0132] In one feasible implementation, the operating status of the heat pump system and the heating system can be determined based on the comparison between the difference and a preset energy cost ratio. For example, the heat pump system can be controlled to increase its heating capacity and the heating system can be controlled to decrease its heating capacity based on the comparison between the difference and the preset energy cost ratio; or, the heating system can be controlled to increase its heating capacity and the heat pump system can be controlled to decrease its heating capacity based on the comparison between the difference and the preset energy cost ratio.

[0133] In this embodiment, by controlling the operation of the heat pump system and the heating system based on the energy difference and a preset energy cost ratio, the system can select either the heat pump system or the heating system according to actual conditions, effectively reducing energy consumption and thus lowering energy costs. Furthermore, selecting a more economical energy supply method based on the preset energy cost ratio can reduce heating costs and improve energy efficiency. In addition, adjusting the operation of the heating system and the heat pump system based on the energy difference ensures that the indoor temperature remains within a comfortable range, enhancing comfort.

[0134] Furthermore, in one embodiment, step S22 includes steps S221 to S222:

[0135] Step S221: When the difference is greater than the preset energy cost ratio, control the heat pump system to increase the heating capacity and control the heating system to decrease the heating capacity.

[0136] When the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system is greater than the preset energy cost ratio, it means that the energy cost ratio of the heat pump system is greater than that of the heating system. In this case, under the same heating capacity, the operating cost of the heat pump system is less than that of the heating system, or under the same operating cost, the heating capacity of the heat pump system is greater than that of the heating system. Therefore, when the difference is greater than the preset energy cost ratio, increasing the heating capacity of the heat pump system and decreasing the heating capacity of the heating system can optimize the cost, reduce heating costs, and improve the heating effect.

[0137] In one feasible implementation, when the difference is greater than a preset energy cost ratio and the duration reaches a preset duration, the heat pump system can be controlled to increase its heating capacity and the heating system can be controlled to decrease its heating capacity.

[0138] Step S222: When the difference is less than or equal to the preset energy cost ratio, control the heating system to increase the heating capacity and control the heat pump system to decrease the heating capacity.

[0139] When the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system is less than or equal to the preset energy cost ratio, it means that the energy cost ratio of the heating system is greater than that of the heat pump system. In this case, under the same heating capacity, the operating cost of the heating system is less than that of the heat pump system, or under the same operating cost, the heating capacity of the heating system is greater than that of the heat pump system. Therefore, when the difference is less than or equal to the preset energy cost ratio, increasing the heating capacity of the heating system and decreasing the heating capacity of the heat pump system can optimize the cost, reduce heating costs, and improve heating performance.

[0140] In one feasible implementation, when the current difference is less than or equal to a preset energy cost ratio and the duration reaches a preset duration, the heating system can be controlled to increase its heating capacity and the heat pump system can be controlled to decrease its heating capacity.

[0141] In this embodiment, by means of the above method, the operating status of the heating system and the heat pump system can be controlled according to the comparison result between the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system and the preset energy cost ratio, so as to achieve reasonable scheduling of the two heating resources and optimize the operating costs. This not only achieves the effect of indoor heating, but also reduces energy consumption and heating costs.

[0142] In one embodiment, the heating system includes radiant terminal equipment and gas equipment, and the heat pump system includes convective heat exchange equipment.

[0143] When the heating system increases its heating capacity, the gas equipment heats the refrigerant flowing through it by burning gas. The heated refrigerant then flows into the radiant terminal equipment in the corresponding indoor space through the fluid regulation module. After the heated refrigerant is conducted to the radiant terminal equipment, it releases heat, thus heating the air in the indoor space where the radiant terminal equipment is located. Then, after releasing heat, the cooled refrigerant returns to the gas equipment through a heat exchange device for continuous reheating. Through this continuous reheating cycle, the indoor space where the radiant terminal equipment is located achieves the desired heating effect.

[0144] When the convection heat exchanger operates in heating mode, the refrigerant discharged from the compressor flows sequentially through the second heat exchanger, the convection heat exchanger, the throttling device, and the first heat exchanger before returning to the compressor. Both the second and convection heat exchangers are in a heat-releasing state, while the first heat exchanger is in a heat-absorbing state. During this process, the refrigerant in the refrigerant circulation system circulates, absorbing heat released by the second heat exchanger as it flows through the heat exchange modules before flowing to the convection heat exchanger. When the convection heat exchanger in the indoor space requiring heating is activated, it releases heat into the space it occupies, thus achieving the heating effect.

[0145] In heating mode, convection heat exchangers and radiant terminal units have different effects on indoor temperature, mainly in terms of temperature uniformity and heating efficiency. For convection heat exchangers, because their air outlets are typically located higher in the room, hot air primarily affects the upper levels. This design can sometimes lead to temperature stratification, with higher temperatures in the upper levels and lower temperatures near the ground. This stratification can reduce indoor comfort, as the body primarily feels the heat from its lower body. However, the heating performance of convection heat exchangers is generally stable and can meet the needs of most households. Especially when outdoor temperatures are not too low, the heating effect of convection heat exchangers can be quite ideal.

[0146] In contrast, radiant floor heating provides a more even heating experience. Radiant floor heating works by laying pipes under the floor to conduct heat generated by hot water or electric heating elements to the ground, where it is then radiated evenly throughout the room. This method results in a more uniform indoor temperature distribution, preventing noticeable temperature stratification. Furthermore, radiant floor heating is more comfortable because the heat is transferred upwards, aligning with human physiological needs.

[0147] From the perspective of temperature uniformity and heating effect, radiant terminal equipment has a greater advantage over convection heat exchange equipment. Radiant terminal equipment can make the indoor temperature distribution more uniform, improving the comfort of indoor occupants. In actual use, because radiant terminal equipment heats up more slowly than convection heat exchange equipment, both radiant terminal equipment and convection heat exchange equipment can be turned on simultaneously to achieve rapid indoor temperature rise. That is, both convection heat exchange equipment and radiant terminal equipment are controlled to operate in heating mode at the same time, so that the indoor temperature meets the comfort requirements. However, when operating radiant terminal equipment and convection heat exchange equipment simultaneously, the energy of radiant terminal equipment and convection heat exchange equipment must be rationally allocated to achieve optimal operating costs and reduce heating costs.

[0148] Furthermore, in one embodiment, the environmental control system further includes a refrigerant circulation system, the heating system includes a gas-fired device, the refrigerant circulation system includes a first circulation branch and a second circulation branch, the heat exchange module in the first circulation branch is connected to the heat pump system for heat exchange, the second circulation branch is connected to the second circulation branch for heat exchange, the gas-fired device is located in the second circulation branch, wherein the heat exchange module may be a hydraulic module, the hydraulic module is mainly used to provide hot water to radiant terminal devices, etc., to increase the indoor temperature.

[0149] In one feasible implementation, step S221, controlling the heat pump system to increase its heating capacity and controlling the heating system to decrease its heating capacity, includes: increasing the target increment of the heat exchange module and decreasing the target increment of the gas equipment; controlling the operation of the heat pump system based on the current target increment of the heat exchange module and controlling the operation of the heating system based on the current target increment of the gas equipment.

[0150] The target increment of the heat exchange module refers to the target temperature difference between the outlet and return temperatures of the heat exchange module. Specifically, the target increment of the heat exchange module is obtained based on the temperature difference between the outlet and return temperatures. The outlet temperature refers to the temperature of the water outlet pipe of the heat exchange module, which is also the inlet water temperature on the hydraulic module side of the coupling tank; the return temperature refers to the return water temperature of the heat exchange module, which is also the outlet water temperature of the manifold.

[0151] The target increment of the gas equipment refers to the target temperature difference between the total liquid outlet temperature and the liquid outlet temperature of the heat exchange module. That is, the target increment of the gas equipment is obtained based on the temperature difference between the total liquid outlet temperature and the liquid outlet temperature of the heat exchange module. The total liquid outlet temperature refers to the temperature of the water supplied downstream, the total water supply temperature, the water outlet temperature on the hydraulic module side of the coupling tank, and the target refrigerant temperature of the refrigerant circulation system.

[0152] After increasing the target increment of the heat exchange module and decreasing the target increment of the gas equipment, the current target increment of the heat exchange module and the current target increment of the gas equipment are obtained. Then, the operation of the heat pump system is controlled according to the current target increment of the heat exchange module, and the operation of the heating system is controlled according to the current target increment of the gas equipment.

[0153] In this embodiment, by increasing the target increment of the heat exchange module and controlling the operation of the heat pump system according to the current target increment of the heat exchange module, the heating capacity of the heat pump system is increased. Conversely, by decreasing the target increment of the gas equipment and controlling the operation of the heating system according to the current target increment of the gas equipment, the heating capacity of the heating system is reduced.

[0154] Step S222, controlling the heating system to increase its heating capacity and controlling the heat pump system to decrease its heating capacity, includes: increasing the target increment of the gas equipment and decreasing the target increment of the heat exchange module; controlling the operation of the heating system based on the current target increment of the gas equipment, and controlling the operation of the heat pump system based on the current target increment of the heat exchange module.

[0155] After increasing the target increment of the gas equipment and decreasing the target increment of the heat exchange module, the current target increment of the heat exchange module and the current target increment of the gas equipment are obtained. Then, the operation of the heating system is controlled according to the current target increment of the gas equipment, and the operation of the heat pump system is controlled according to the current target increment of the heat exchange module.

[0156] In this embodiment, by reducing the target increment of the heat exchange module and controlling the operation of the heat pump system according to the current target increment of the heat exchange module, the heating capacity of the heat pump system is reduced. By increasing the target increment of the gas equipment and controlling the operation of the heating system according to the current target increment of the gas equipment, the heating capacity of the heating system is increased, thereby achieving a reasonable distribution of energy between the heat pump system and the heating system.

[0157] In one embodiment, the target refrigerant temperature of the refrigerant circulation system can be obtained, the temperature difference between the target refrigerant temperature and the return liquid temperature of the heat exchange module can be determined, and the sum of the target increment of the heat exchange module and the target increment of the gas equipment can be determined based on the temperature difference.

[0158] The target refrigerant temperature is the desired temperature that the refrigerant in the refrigerant circulation system needs to reach during the operation of the gas appliance. The target refrigerant temperature is lower than the aforementioned target outlet temperature. The target refrigerant temperature can have different values ​​depending on the detection location. The target refrigerant temperature can be a preset fixed temperature or a temperature determined based on the actual operation of the environmental control system. For example, it can be set by the user (the user sets the water supply temperature of the radiant module equipment, i.e., a constant water temperature radiant terminal device) or generated by the room temperature control logic (the user sets the room temperature, and the variable water temperature control reaches the user-set room temperature).

[0159] The temperature difference between the target refrigerant temperature and the return liquid temperature of the heat exchange module can be called the target refrigerant temperature increment. The target refrigerant temperature increment is equal to the sum of the target increment of the heat exchange module and the target increment of the gas equipment. Since the target refrigerant temperature and the return liquid temperature of the heat exchange module are known, the target refrigerant temperature increment is also known. Therefore, the sum of the target increment of the heat exchange module and the target increment of the gas equipment can be determined based on the target refrigerant temperature increment. It can be understood that, under the same target refrigerant temperature increment, when the target increment of the heat exchange module increases, the target increment of the gas equipment decreases, or when the target increment of the gas equipment decreases, the target increment of the heat exchange module increases, thus achieving a reasonable allocation of the target increment of the heat exchange module and the target increment of the gas equipment.

[0160] Among them, the temperature difference value mentioned above is greater than or equal to 0, the target increment of the heat exchange module is greater than or equal to 0, and the target increment of the gas equipment is greater than or equal to 0.

[0161] In another feasible implementation, step S221, controlling the heat pump system to increase its heating capacity and controlling the heating system to decrease its heating capacity, includes: determining the current target increment of the heat exchange module based on the temperature difference between the target refrigerant temperature of the refrigerant circulation system and the return liquid temperature of the heat exchange module; controlling the heat pump system to operate based on the current target increment of the heat exchange module, and controlling the gas equipment to shut down.

[0162] The temperature difference is the target refrigerant temperature increment. This temperature difference is equal to the sum of the target increment of the heat exchange module and the target increment of the gas equipment.

[0163] The target increment of the heat exchange module can be determined based on the temperature difference between the target refrigerant temperature of the refrigerant circulation system and the return liquid temperature of the heat exchange module. Then, the operation of the heat pump system is controlled and the gas equipment is shut down based on the current target increment of the heat exchange module. In this case, the target increment of the gas equipment is 0, and the target increment of the heat exchange module can be obtained based on the difference between the temperature difference and the target increment of the gas equipment. This ensures that when the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system is greater than the preset energy cost ratio, the heat exchange module will be responsible for all heating, and the gas equipment will not participate in heating.

[0164] Furthermore, in one embodiment, the heat pump system includes a compressor and an indoor unit, the indoor unit including an indoor fan. Controlling the operation of the heat pump system according to the current target increment of the heat exchange module includes: obtaining the temperature difference between the current outlet temperature and return temperature of the heat exchange module; when the temperature difference is less than the current target increment of the heat exchange module, increasing the operating frequency of the compressor and / or the speed of the indoor fan; when the temperature difference is greater than the current target increment of the heat exchange module, decreasing the operating frequency of the compressor and / or the speed of the indoor fan.

[0165] In this embodiment, the higher the compressor's operating frequency and the higher the indoor fan speed, the greater the water temperature increment. When the temperature difference is less than the heat exchange module's current target increment, it indicates that the current indoor temperature does not meet the requirements. In this case, the compressor's operating frequency and / or the indoor fan speed are increased to quickly increase the water temperature increment and improve the heat pump system's heating capacity, thus preventing insufficient indoor temperature. When the temperature difference is greater than the heat exchange module's current target increment, it indicates that the current indoor temperature meets the requirements. In this case, the compressor's operating frequency and / or the indoor fan speed are decreased to reduce the water temperature increment and decrease the heat pump system's heating capacity, thus preventing overheating and improving indoor comfort.

[0166] Step S222, controlling the heating system to increase its heating capacity and controlling the heat pump system to decrease its heating capacity, includes: determining the current target increment of the gas equipment based on the temperature difference between the target refrigerant temperature of the refrigerant circulation system and the return liquid temperature of the heat exchange module; controlling the operation of the gas equipment and controlling the heat pump system to shut down based on the current target increment of the gas equipment.

[0167] The target increment of the gas equipment can be determined based on the temperature difference between the target refrigerant temperature of the refrigerant circulation system and the return liquid temperature of the heat exchange module. Then, the operation of the gas equipment is controlled based on the current target increment, and the heat pump system is controlled to shut down. In this case, the target increment of the heat exchange module is 0, and the target increment of the gas equipment can be obtained based on the difference between the temperature difference and the target increment of the heat exchange module. This ensures that when the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system is less than or equal to a preset energy cost ratio, the gas equipment provides all heating, and the heat exchange module does not participate in heating.

[0168] Furthermore, in one embodiment, the heating system further includes a circulation pump located in the second circulation branch. The step of controlling the operation of the gas equipment according to the current target increment of the gas equipment includes: obtaining the temperature difference between the current outlet temperature and the return temperature of the gas equipment; when the temperature difference is less than the current target increment of the gas equipment, increasing the opening of the gas proportional valve of the gas equipment and / or the rotation speed of the circulation pump; when the temperature difference is greater than the current target increment of the gas equipment, decreasing the opening of the gas proportional valve of the gas equipment and / or the rotation speed of the circulation pump.

[0169] The circulating pump is a variable frequency water pump.

[0170] In this embodiment, the higher the current outlet temperature of the gas appliance, the higher the rotation speed of the gas appliance's circulation pump. Specifically, when the temperature difference between the current outlet and return temperatures of the gas appliance is less than the target temperature increment, it indicates that the current indoor temperature does not meet the requirements. In this case, the opening of the gas proportional valve and / or the rotation speed of the circulation pump are increased to quickly increase the water temperature increment, thereby improving the heating capacity of the heating system and preventing insufficient indoor temperature. When the difference is greater than the target temperature increment, it indicates that the current indoor temperature meets the requirements. In this case, the opening of the gas proportional valve and / or the rotation speed of the circulation pump are decreased to reduce the water temperature increment, thereby reducing the heating capacity of the heating system and preventing overheating, thus improving indoor comfort.

[0171] In one embodiment, the heating capacity of the heating system can be increased by controlling the gas equipment to increase the number of ignited burners and the amount of air in the combustion chamber. Conversely, the heating capacity of the heating system can be reduced by controlling the gas equipment to decrease the number of ignited burners and the amount of air in the combustion chamber.

[0172] In one embodiment, when the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system is greater than a preset energy cost ratio and the duration of this difference reaches a preset duration, it indicates that the energy cost ratio of the heat pump system is always greater than that of the heating system. Therefore, using a heat pump system for heating can reduce heating costs. Thus, the current target increment of the heat exchange module is determined based on the temperature difference between the target refrigerant temperature of the refrigerant circulation system and the return liquid temperature of the heat exchange module. The operation of the heat pump system is controlled based on the current target increment of the heat exchange module, while the gas equipment is shut down, meaning that all heating is provided by the heat pump system, thereby reducing heating costs. When the difference between the energy cost ratio of the heat pump system and the energy cost ratio of the heating system is less than or equal to the preset energy cost ratio and the duration reaches the preset duration, it indicates that the energy cost ratio of the heating system is greater than that of the heat pump system. Using the heating system for heating can reduce heating costs. Therefore, the current target increment of the gas equipment is determined based on the temperature difference between the target refrigerant temperature of the refrigerant circulation system and the return liquid temperature of the heat exchange module. The operation of the gas equipment is controlled based on the current target increment of the gas equipment, and the heat pump system is controlled to shut down, that is, the heating is entirely provided by the heating system, thereby reducing heating costs.

[0173] Based on the first and second embodiments of this application, in the third embodiment of this application, the content that is the same as or similar to the first and second embodiments described above can be referred to the above description and will not be repeated hereafter. Based on this, obtaining the first parameter of the heat pump system in step S10 includes steps S11 to S12:

[0174] Step S11: Obtain the heat pump energy efficiency of the heat pump system and the electricity price;

[0175] Heat pump energy efficiency is commonly used to measure the performance and efficiency of a heat pump system. The higher the heat pump energy efficiency, the less electricity the device consumes to provide the same cooling capacity; in other words, the better the energy efficiency.

[0176] The heat pump efficiency of a heat pump system varies under different ambient temperatures. For example, the heat pump efficiency of a heat pump system can be determined based on the indoor temperature and / or outdoor temperature. A correspondence between different indoor and / or outdoor temperatures and the heat pump efficiency of the heat pump system can be pre-built. The heat pump efficiency of the heat pump system can be obtained based on the current indoor and / or outdoor temperature and the pre-built correspondence.

[0177] The electricity price for a heat pump system can be fixed or determined based on at least one of the system's heat pump efficiency, power consumption, and the time of day it is used. Different heat pump efficiencies, power consumptions, and time periods correspond to different electricity prices. A pre-established relationship between these relationships and the corresponding electricity prices can be constructed. The electricity price for the heat pump system can then be determined based on the current heat pump efficiency, current power consumption, current time period, and the pre-established relationship.

[0178] It is also possible to pre-build the correspondence between different indoor and / or outdoor temperatures, the heat pump efficiency of the heat pump system, and the electricity price. Based on the current indoor and / or outdoor temperatures and the pre-built correspondence between indoor and / or outdoor temperatures, the heat pump efficiency of the heat pump system, and the electricity price, the electricity price of the heat pump system can be obtained. Since the heat pump efficiency and electricity price of the heat pump system can be determined according to different indoor and / or outdoor temperatures, the acquisition of the heat pump efficiency and electricity price of the heat pump system meets the requirements of seasonal differences, thereby improving the accuracy of the heat pump system's operating energy cost ratio.

[0179] Step S12: Determine the operating energy cost ratio of the heat pump system based on the heat pump energy efficiency of the heat pump system and the electricity price.

[0180] In one feasible implementation, the correspondence between the heat pump energy efficiency, electricity price and the heat pump system operating energy cost ratio can be pre-established, and the heat pump system operating energy cost ratio can be obtained based on the current heat pump energy efficiency, electricity price and the correspondence.

[0181] In another feasible implementation, the operating energy cost ratio of the heat pump system can be obtained based on the ratio of the heat pump energy efficiency of the heat pump system to the electricity price. It can be understood that when the heat pump energy efficiency of the heat pump system is constant, the higher the electricity price of the heat pump system, the lower the operating energy cost ratio of the heat pump system, and the lower the electricity price of the heat pump system, the higher the operating energy cost ratio of the heat pump system.

[0182] For example, assuming an outdoor temperature of 7℃ and an indoor temperature of 20℃, the heat pump efficiency of the heat pump system is 4.0W / W, and the electricity price is 0.6 yuan / kWh. Then the energy cost ratio of the heat pump system is 4.0 ÷ 0.6 = 6.67 kWh / yuan. Assuming an outdoor temperature of -15℃ and an indoor temperature of 20℃, the heat pump efficiency of the heat pump system is 1.5W / W, and the electricity price is 0.8 yuan / kWh. Then the energy cost ratio of the heat pump system is 1.5 ÷ 0.8 = 1.88 kWh / yuan.

[0183] In this embodiment, the energy cost ratio of the heat pump system is determined based on the heat pump energy efficiency and electricity price, taking into account both electricity price and heat pump energy efficiency, so as to achieve reasonable scheduling of the two heating resources, the heat pump system and the heating system, through the energy cost ratio of the heat pump system.

[0184] Furthermore, in one embodiment, the environmental control system further includes a refrigerant circulation system, and obtaining the heat pump energy efficiency of the heat pump system in step S11 includes steps S111 to S112:

[0185] Step S111: Obtain the refrigerant temperature of the refrigerant circulation system, the outdoor temperature, and the heating load rate corresponding to the heat pump system.

[0186] The refrigerant temperature can be determined based on the actual outlet and return temperatures of the heat exchange module. For example, the average of the actual outlet and return temperatures of the heat exchange module can be used as the refrigerant temperature. Alternatively, the refrigerant temperature can also be the maximum outlet temperature, maximum return temperature, minimum outlet temperature, minimum return temperature, etc.

[0187] Heating load factor refers to the ratio of the heating capacity required by a building or equipment to the actual capacity of the heating system. It is used to measure whether a heat pump system can meet the heating needs of a building or equipment, and the heating load factor corresponding to the heat pump system can be determined based on the heat pump system and its rated heating capacity.

[0188] In one feasible implementation, the heating capacity and rated heating capacity of the heat pump system are obtained; based on the heating capacity and rated heating capacity of the heat pump system, the corresponding heating load rate of the heat pump system is determined. For example, the heating load rate of the heat pump system is obtained based on the ratio between the heating capacity and the rated heating capacity, wherein the rated heating capacity can be fixed according to actual conditions.

[0189] Furthermore, in one embodiment, the refrigerant circulation system includes a first circulation branch, in which a heat exchange module is connected to the heat pump system for heat exchange. Obtaining the heating capacity of the heat pump system includes: obtaining the refrigerant flow rate of the refrigerant circulation system, the outlet temperature of the heat exchange module, and the return temperature of the heat exchange module; and determining the heating capacity of the heat pump system based on the refrigerant specific heat capacity, refrigerant density, refrigerant flow rate of the refrigerant circulation system, the outlet temperature of the heat exchange module, and the return temperature of the heat exchange module. For example, the heating capacity of the heat pump system can be determined according to the following formula: Heating capacity of the heat pump system = Refrigerant specific heat capacity × Refrigerant density × Refrigerant flow rate of the refrigerant circulation system × (Outlet temperature of the heat exchange module - Return temperature of the heat exchange module), where the refrigerant specific heat capacity is 4.2 KJ / (kg℃) and the refrigerant density is 1000 kg / m³. 3 The flow rate (m³) of the refrigerant in the refrigerant circulation system is detected by using a flow meter or a water pump with flow detection function. 3 / s), or estimate the refrigerant flow rate of the refrigerant circulation system based on engineering design and commissioning data. The refrigerant flow rate of the refrigerant circulation system is the actual refrigerant flow rate.

[0190] Step S112: Determine the heat pump efficiency of the heat pump system based on the refrigerant temperature, the outdoor temperature, and the heating load rate.

[0191] In one feasible implementation, a target correspondence between refrigerant temperature, outdoor temperature, heating load rate and energy efficiency can be pre-established, and the heat pump energy efficiency of the heat pump system can be determined based on the target correspondence.

[0192] In another feasible implementation, a target correspondence between the outdoor temperature, the heating load rate, and the energy efficiency is determined based on the refrigerant temperature, with different refrigerant temperatures corresponding to different target correspondences; the heat pump energy efficiency of the heat pump system corresponding to the outdoor temperature and the heating load rate is determined based on the target correspondence.

[0193] The heat pump efficiency (EER) is obtained by referring to a table based on the refrigerant temperature, heating load rate, and outdoor temperature, and then performing linear interpolation. The correspondence between refrigerant temperature, heating load rate, outdoor temperature, and heat pump efficiency is shown in the table below, where EER represents the heat pump efficiency of the system.

[0194]

[0195]

[0196] As shown in the table above, there is a certain correlation between refrigerant temperature, outdoor temperature, heating load rate, and the heat pump efficiency of the heat pump system. Details are as follows:

[0197] When the refrigerant temperature increases, the heat pump efficiency of the heat pump system decreases; when the refrigerant temperature decreases, the heat pump efficiency of the heat pump system increases. In other words, there is a negative correlation between the refrigerant temperature and the heat pump efficiency of the heat pump system.

[0198] When the outdoor temperature rises, the heat pump efficiency of the heat pump system increases; when the outdoor temperature falls, the heat pump efficiency of the heat pump system decreases. That is, there is a positive correlation between outdoor temperature and the heat pump efficiency of the heat pump system.

[0199] Before a certain preset heating load rate, as the heating load rate increases, the heat pump efficiency of the heat pump system increases, showing a positive correlation between the heating load rate and the heat pump efficiency. After a certain preset heating load rate, as the heating load rate increases, the heat pump efficiency of the heat pump system decreases, showing a negative correlation. The preset heating load rate can be determined based on the actual conditions of different heat pump systems.

[0200] In summary, there is a certain correlation between refrigerant temperature, outdoor temperature, and heating load rate and the heat pump energy efficiency of a heat pump system. Proper design and selection can effectively meet the heating needs of buildings or equipment, thereby improving energy efficiency and reducing energy consumption.

[0201] In one embodiment, the second parameter includes the energy cost ratio of the heating system, and the second parameter of the heating system in step S10 includes steps S13 to S14:

[0202] Step S13: Obtain the gas energy efficiency and gas price of the heating system;

[0203] The gas energy efficiency of a heating system is preset and directly obtainable, or it can be determined based on actual conditions. A heating system includes gas-fired equipment, and the gas energy efficiency of the heating system is the gas energy efficiency of the gas-fired equipment.

[0204] Different gas efficiencies in heating systems correspond to different gas prices. A pre-built relationship between different gas efficiencies and their corresponding gas prices can be established, and the gas price of the heating system can be obtained based on the current heating system and the pre-built relationship between gas efficiencies and gas prices.

[0205] Different gas consumption levels correspond to different gas prices. A pre-defined relationship between different gas consumption levels of a heating system and their corresponding gas prices can be established. Based on the current heating system and the pre-defined relationship, the gas price for the heating system can be calculated. For example, the specific values ​​for the first, second, and third tiers of gas pricing in a certain region will be adjusted according to different years. The following values ​​are for reference only:

[0206] The first tier has an annual gas consumption of 0-360 cubic meters (inclusive) per household, with a gas price of 2.53 yuan per cubic meter.

[0207] The second tier has an annual gas consumption of 360-600 cubic meters (inclusive) per household, with a gas price of 2.78 yuan per cubic meter.

[0208] The third tier has an annual gas consumption of 600 cubic meters or more per household, with a gas price of 3.54 yuan per cubic meter.

[0209] It is also possible to pre-build the correspondence between different indoor and / or outdoor temperatures, the gas energy efficiency of the heating system, and the gas price. Based on the current indoor and / or outdoor temperatures and the pre-built correspondence between indoor and / or outdoor temperatures, the gas price of the heating system can be obtained. Since the gas energy efficiency and gas price of the heating system can be determined according to different indoor and / or outdoor temperatures, the acquisition of the gas energy efficiency and gas price of the heating system meets the requirements of seasonal differences, thus improving the accuracy of the second parameter of the heating system.

[0210] Since the electricity price varies at different times and for different amounts of electricity consumption, and the gas price varies at different times and for different amounts of gas consumption, the operating costs of the heat pump system and the heating system are different. By reasonably controlling the heat energy system and the heating system, the heating cost of the entire environmental regulation system can be reduced.

[0211] Step S14: Determine the operating energy cost ratio of the heating system based on the gas energy efficiency of the heating system and the gas price.

[0212] In one feasible implementation, the correspondence between the gas energy efficiency, gas price, and energy cost ratio of the heating system can be pre-established, and the energy cost ratio of the heating system can be obtained based on the current gas energy efficiency, gas price, and the correspondence.

[0213] In another feasible implementation, the operating energy cost ratio of the heating system can be obtained based on the ratio of the gas energy efficiency of the heating system to the gas price. It can be understood that when the gas energy efficiency of the heating system is constant, the higher the gas price, the lower the operating energy cost ratio of the heating system, and the lower the gas price, the higher the operating energy cost ratio of the heating system.

[0214] For example, assuming the gas efficiency of the heating system is 107% and the gas price is 3.64 yuan / m³ 3 Therefore, the energy-cost ratio of the heating system is 107% × 36.44 MJ ÷ 3.64 = 2.98 kWh / yuan; assuming the gas efficiency of the heating system is 107% and the gas price is 2.78 yuan / m³. 3The energy cost ratio of the heating system is 107% × 36.44 MJ ÷ 2.78 = 3.90 kWh / yuan.

[0215] In this embodiment, the energy cost ratio of the heating system is determined based on the gas energy efficiency and gas price of the heating system. This takes into account both gas price and gas energy efficiency, and enables the rational scheduling of the two heating resources, the heat pump system and the heating system, through the energy cost ratio of the heating system.
