Detailed Description
For a clearer understanding of the technical features, objects and effects of the present invention, a detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1, in a first embodiment of a heating system control method of the present invention, wherein the heating system includes a heating apparatus, and a bathroom apparatus, and a main circuit connected to the heating apparatus, a first heating branch connected to the main circuit and the heating apparatus, and a second heating branch connected to the main circuit and the bathroom apparatus; the method comprises the following steps: s1, when only the heating equipment is put into use, acquiring the temperature of the water outlet end of the bathroom equipment; s2, comparing the temperature of the water outlet end of the bathroom equipment with a preset anti-freezing starting temperature, and adjusting the flow of the second heat supply branch when the temperature of the water outlet end of the bathroom equipment is smaller than the preset anti-freezing starting temperature; s3, comparing the temperature of the water outlet end of the bathroom equipment with a preset anti-freezing stop temperature, and stopping adjusting the flow of the second heat supply branch when the temperature of the water outlet end is not smaller than the preset anti-freezing stop temperature. Specifically, in the heating system, heat generated by the heating device can be output through the main loop and input to the heating device through the first heat supply branch to supply heat to the heating device. Meanwhile, after the heat generated by the heat supply equipment is output through the main loop, the heat can be input into the bathroom equipment through the second heat supply branch circuit to supply heat for the bathroom equipment. The first heat supply branch can form a large heat supply cycle, and the second heat supply branch can form a small heat supply cycle.
In the heating system, when the bathroom equipment is not put into use, the first heating branch and the second heating branch can be controlled to prevent freezing of the bathroom equipment. Specifically, if only the heating equipment is put into use, only the first heating branch works normally, and the second heating branch is in an off state because the bathroom equipment is not put into use at the moment, i.e. the second heating branch does not provide heat supply. In this case, if the temperature is too low, components in the sanitary installation, for example the plate heat exchanger, may be frozen out. Therefore, the temperature of the water outlet end of the bathroom equipment can be monitored when only the heating equipment is put into use. Acquiring the water outlet end temperature of the bathroom equipment, and confirming whether the water outlet end temperature of the bathroom equipment is smaller than a preset anti-freezing starting temperature. When the temperature of the water outlet end of the bathroom equipment is smaller than the preset anti-freezing starting temperature, the plate type heat exchanger is indicated to have the risk of freezing, and the flow of the second heat supply branch circuit can be adjusted at the moment, so that the heat supply of the main loop can supply heat to the bathroom equipment through the second heat supply branch circuit, and the temperature of the bathroom equipment is raised. In the process of raising the temperature of the water outlet end of the bathroom equipment, when the temperature of the water outlet end of the bathroom equipment is no longer smaller than the preset anti-freezing stop temperature, the flow of the second heat supply branch is no longer regulated, namely the heat supply to the bathroom equipment is no longer regulated. At this point the temperature of the sanitary equipment is raised and it does not risk freezing.
The adjusting process can adopt a PID adjusting process, and the flow of the second heat supply branch is adjusted according to the difference value between the temperature of the water outlet end of the current bathroom equipment and the preset antifreezing stop temperature. Second heat supply branchThe step increment of the flow adjustment of the road is recorded as delta step Obtaining an adjustment amount through the following PID formula;
Δ step ＝K p *(E i ―E ii )+K i *E i +K d *(E i ―2E ii +E iii )，
wherein K is p Is a proportional coefficient, ki is an integral coefficient, K d As a differential coefficient, E i For the current temperature difference, E ii For the last temperature difference, E iii The temperature difference value is the last temperature difference value; obtaining the current callback adjustment quantity as C according to the formula step ＝L step +Δ step . Wherein L is step The step quantity which is called back last time is recorded as C step Is the step size of the current callback.
Optionally, as shown in fig. 2, in an embodiment of the heating system operation control method of the present invention, the method further includes: s21, monitoring the flow of the first heat supply branch, and stopping adjusting the flow of the second heat supply branch when the flow of the first heat supply branch is not larger than a first preset value. Specifically, when the bathroom equipment is used for preventing freezing, the minimum heat supply quantity of the heating equipment is required to be ensured, so that the flow of the first heat supply branch is required to be monitored while the flow of the second heat supply branch is regulated, namely, the flow of the first heat supply branch is ensured to be not smaller than a first preset value. Therefore, the adjustment of the flow rate of the second heating branch may be stopped when the flow rate of the first heating branch is not greater than the first preset value. It can also be appreciated that the flow of the second heating branch can be stopped from being adjusted before the temperature of the water outlet end of the bathroom equipment reaches the preset freeze stop temperature.
Optionally, as shown in fig. 3, in an embodiment of the heating system operation control method of the present invention, the method further includes: s22, comparing the water outlet end temperature of the bathroom equipment with a preset anti-freezing stop temperature, and adjusting the heat supply temperature of the main loop when the water outlet end temperature of the bathroom equipment is smaller than the preset anti-freezing stop temperature so that the water outlet end temperature of the bathroom equipment reaches the preset anti-freezing stop temperature. Specifically, in some cases, since the heating of the heating device is to be ensured, it may happen that the flow adjustment process of the second heating branch is stopped when the temperature of the water outlet end of the bathroom device has not reached the preset freezing stop temperature. The heating temperature of the main circuit can be adjusted at this time. The power of the heating equipment can be increased to improve the heating temperature of the main loop, so that the temperature can be raised under the condition that the flow of the second heating branch is certain, and finally the temperature of the water outlet end of the bathroom equipment reaches the preset anti-freezing stop temperature.
Optionally, as shown in fig. 4 and fig. 5, in an embodiment of the heating system operation control method of the present invention, the method further includes: and S4, adjusting the heating temperature of the main loop to enable the heating backwater temperature corresponding to the heating equipment to reach the preset heating backwater target temperature. Specifically, if the temperature of the heating return water is too low in the flow adjustment process of the second heating branch, and deviates from the preset heating return water target temperature, the heating temperature of the main loop can be adjusted. The power of the heating equipment can be increased to improve the heating temperature of the main loop, so that the temperature can be raised under the condition that the flow of the first heating branch is certain, and finally the heating backwater temperature of the heating equipment reaches the preset heating backwater target temperature.
Optionally, in an embodiment of the heating system operation control method of the present invention, the method further includes: when the temperature of the water outlet end of the bathroom equipment is not less than the preset anti-freezing starting temperature, heating backwater temperature corresponding to the heating equipment is obtained, and when the heating backwater temperature is less than the preset heating backwater target temperature, the flow of the second heat supply branch is adjusted so that the heating backwater temperature reaches the preset heating backwater target temperature. Specifically, when the temperature of the water outlet end of the bathroom equipment is not less than the preset anti-freezing starting temperature, after the adjustment process of the flow of the second heat supply branch is finished, the heating water return temperature of the heating equipment is required to be judged, and when the heating water return temperature is less than the preset heating water return target temperature, the flow of the second heat supply branch is adjusted, so that the heating water return temperature can reach the preset heating water return target temperature more rapidly. The regulating process may employ a PID regulating process to regulate the flow of the second heating branch according to the current temperature and the target temperature. In the process, the calculation can be performed based on the PID formula, wherein the temperature value is the difference value between the heating backwater temperature and the heating backwater target temperature.
It can be understood that reducing the heating flow rate of a little will not have an effect on heating, and if there is a more obvious effect, the heating power compensation can be increased;
optionally, as shown in fig. 6, in an embodiment of the heating system operation control method of the present invention, the method further includes: a1, when the heating equipment and the bathroom equipment are put into use, setting a ratio of the flow of the first heat supply branch to the flow of the second heat supply branch to meet a second preset value, judging whether the bathroom equipment reaches an equilibrium state, if so, executing a step A3, otherwise, executing a step A2; a2, acquiring the change rate of the water outlet end temperature of the bathroom equipment, and adjusting the flow of the second heat supply branch when the change rate is smaller than the preset temperature rise rate so that the change rate of the water outlet end temperature of the bathroom equipment reaches the preset temperature rise rate, and A3, adjusting the flow of the second heat supply branch so that the water outlet end temperature of the bathroom equipment is the target water outlet temperature of the bathroom equipment. Specifically, when both the heating device and the bathroom device are in use, the ratio of the flow of the first heat supply branch to the flow of the second heat supply branch is set to a preset value, i.e. the second preset value, for example, in an embodiment, the initial flow ratio of the small cycle to the large cycle may be set to 7:3. When the small circulation works at the current flow, judging whether the working state of the bathroom equipment reaches an equilibrium state or not. It is understood that the equilibrium state of the sanitary equipment refers to a state when the temperature of the water outlet end of the sanitary equipment is stabilized at a certain temperature. For example, when the temperature of the water outlet end of the bathroom equipment is stabilized at a certain preset temperature, the current bathroom equipment is judged to reach an equilibrium state. When the bathroom equipment is judged to be in the balance state, whether the water outlet end temperature of the bathroom equipment is the target water outlet temperature of the bathroom is confirmed, and when the water outlet temperature of the bathroom equipment is not the target water outlet temperature of the bathroom, the small circulation flow is regulated, so that the water outlet temperature of the bathroom equipment is the target temperature of the bathroom. When the bathroom equipment does not enter the equilibrium state yet, judging the change rate of the temperature of the water outlet end of the bathroom equipment, and confirming whether the change rate meets the preset temperature rise rate or not. Since the water outlet rate of the hot water needs to be prioritized when domestic hot water is required, for example, when a shower is taking, the water outlet cannot be too slow, which can affect the shower experience of the user. Therefore, when the change rate is smaller than the preset temperature rise rate, the flow of the small circulation is adjusted so that the change rate of the temperature of the water outlet end of the bathroom equipment is equal to the preset temperature rise rate. In the process of adjusting the flow of the small loop, the process of adjusting the flow of the small loop can be set according to the relation between the current change rate and the preset temperature rise rate. When the change rate of the temperature of the water outlet end of the bathroom equipment reaches the preset temperature rise rate, the flow of the small circulation can be further adjusted, so that the temperature of the water outlet end of the bathroom equipment reaches the target water outlet temperature of the bathroom equipment. Through the process, the bathroom equipment can rapidly discharge hot water, and meanwhile, the temperature of the hot water discharged by the bathroom equipment can be finally stabilized at the set bathroom target temperature.
Optionally, the heating system further comprises a step three-way valve, wherein an input end of the step three-way valve is connected with the main loop, a first output end of the step three-way valve is connected with the first heating branch, and a second output end of the step three-way valve is connected with the second heating branch; the adjusting the flow rate of the second heating branch comprises: and adjusting the opening of the second output end of the stepping three-way valve according to a preset stepping. Specifically, a stepping three-way valve is arranged in the heating system. And adjusting the flow of the second heat supply branch by adjusting the opening of the second output end of the stepping three-way valve. When the opening of the second output end of the stepping three-way valve is adjusted, the opening of the first output end of the stepping three-way valve is also changed. The sum of the flow at the first output and the flow at the second output will always be equal to the flow at the input.
