Detailed Description
Fig. 1 is a schematic diagram of the relationship of ambient temperature to the heating costs of an air-source heat pump and a gas-fired heating device. As shown in fig. 1, the heating capacity of the air energy product is mainly derived from air, and the higher the ambient temperature is, the more heat absorbed by the compressor consuming the same power, so the heating cost is lower. With the reduction of the ambient temperature, the heat quantity extracted from the air is less and less, the heating capacity is poorer and poorer, and the heating cost is higher when the air energy product is used for heating. The gas heating device (such as a gas water heater) heats by using gas combustion, and the heating efficiency hardly changes along with the ambient temperature, so that the cost of raising the unit water temperature by using the gas hardly changes along with the ambient temperature under the condition that the price of the gas does not fluctuate greatly.
In order to reduce the heating cost and improve the energy-saving performance of a heating system, the application provides the heating system and the control method thereof, so that the advantages of an air energy heat pump and a gas heating device in different environments are brought into play, the advantages are taken, and the energy-saving performance of heating is improved.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below.
FIG. 2 is a schematic diagram of a heating system 010 according to an embodiment of the present application; fig. 3 is a block diagram of a heating system 010 according to an embodiment of the present invention. As shown in fig. 2, the heating system 010 of the present application includes a main loop pipeline 100, and a first heating branch line 110 and a second heating branch line 120 disposed on the main loop pipeline 100, and a water using device, wherein the first heating branch line 110 and the second heating branch line 120 are disposed on the main loop pipeline 100 in parallel; the first heating branch line 110 is provided with an air-energy heat pump 112, the second heating branch line 120 is provided with a gas heating device 122, water flowing through the first heating branch line 110 and the second heating branch line 120 can be heated by the air-energy heat pump 112 and the gas heating device 122, respectively, and is delivered to the water using device through the main loop line 100, and the heating system 010 further includes a controller 160 to control each device to perform a corresponding operation. In the present embodiment, the gas heating device 122 may be a gas water heater.
Specifically, in this embodiment, the first heating branch line 110 is provided with a first check valve 114 and a first water pump 116, and the second heating branch line 120 is provided with a second check valve 124 and a second water pump 126. First check valve 114 and second check valve 124 serve to prevent circulation between first heating branch 110 and second heating branch 120. The first water pump 116 and the second water pump 126 are used to provide power for the hot water cycle. The first water pump 116 and the second water pump 126 are both electrically connected to the controller 160.
In this embodiment, the water using device includes a floor heating 132 and a hot water storage tank 142, which are disposed in parallel on the main loop line 100 through a first water using branch line 130 and a second water using branch line 140, respectively. The first water branch line 130 is provided with a first electromagnetic valve 131, the second water branch line 140 is provided with a second electromagnetic valve 141, and both the first electromagnetic valve 131 and the second electromagnetic valve 141 are electrically connected with the controller 160. Specifically, the floor heating 132 includes a plurality of parallel-connected coils 134, a water separator 136 and a water collector 138. The floor heating 132 is further provided with a first thermometer 139 for detecting the actual water temperature of the floor heating 132, and specifically, the first thermometer 139 may be arranged on the water separator 136. Similarly, the hot water storage tank 142 may be provided with a second thermometer 143 to detect the actual water temperature of the hot water storage tank 142. It should be understood that the actual water temperature of the water using device refers to the actual temperature of the water at the water using device, in this embodiment, the actual water temperature of the floor heating 132 refers to the actual temperature of the water at the floor heating 132, and the actual water temperature of the hot water storage tank 142 refers to the actual temperature of the water at the hot water storage tank 142. The first and second thermometers 139, 143 are each electrically connected to the controller 160.
In this embodiment, the heating system 010 further includes a third thermometer 150 for detecting the ambient temperature, and the third thermometer 150 is electrically connected to the controller 160 to feed back the ambient temperature to the controller 160.
In this embodiment, the controller 160 is configured to:
according to the ambient temperature and/or the using state of the water using device, one of the air-source heat pump 112 and the gas heating device 122 is selected to be started for heating or the heating is carried out together.
By the control strategy, the heating strategy can be conveniently adjusted according to the ambient temperature or the using state of the water using device, so that a more energy-saving mode is selected, or the requirements of users can be better met. For example, if the ambient temperature is too low, the gas heating device 122 is selected to heat; if the ambient temperature is too high, the air-source heat pump 112 is selected for heating; when the load of the water using device is large, the two devices are used for heating simultaneously. Through the flexible selection heating mode, more energy can be saved or the user experience can be improved.
It should be appreciated that in other alternative embodiments of the present application, the water usage device may only contain one of the storage tank 142 or the floor heating 132.
The embodiment of the application provides a control method of a heating system, which can be applied to the heating system 010 provided by the embodiment of the application. The control method comprises the following steps:
according to the ambient temperature and/or the using state of the water using device, one of the air energy heat pump and the gas heating device is selected to be started for heating or the heating is carried out together.
Taking the heating system 010 provided in the embodiment of the present application as an example, the controller 160 may obtain the ambient temperature according to the third thermometer 150. The use state of the water using device includes a set temperature of the water using device, an actual water temperature, whether the floor heating 132 and the hot water storage tank 142 are operated (may be judged by whether the first solenoid valve 131 and the second solenoid valve 141 are opened), and the like. One of the air-energy heat pump 112, the gas heating device 122, or both are controlled to be turned on for heating based on one or more of these factors.
For example, in an embodiment of the present application, depending on the ambient temperature and/or the usage state of the water-using device, one of the air-source heat pump 112 and the gas heating device 122 is selectively turned on to perform heating or perform heating together, which may specifically include:
and when the ambient temperature is not lower than the first preset temperature and the set temperature of the water using device is not higher than the second preset temperature, only starting the air energy heat pump for heating.
Taking the floor heating 132 opened only, when the controller 160 detects that the first solenoid valve 131 is opened, it means that the floor heating 132 is used. When the ambient temperature fed back by the third thermometer 150 is not lower than the first preset temperature and the set temperature of the floor heating 132 is not higher than the second preset temperature, the controller 160 turns on the first water pump 116 and only turns on the air-source heat pump 112 to heat. It can be understood that the single-open hot water storage tank 142 is controlled in a manner similar to the single-open floor heating 132, and the detailed description thereof is omitted here.
Alternatively, the first preset temperature is set to T1 in fig. 1. Thus, above the first predetermined temperature, the air-source heat pump 112 is highly efficient and relatively low cost. The set temperature of the water using device is not greater than the second preset temperature, which means that the actual water temperature of the water using device is not greater than the second preset temperature. Fig. 4 is a graph showing a relationship between the heating cost of the air-source heat pump 112 and the gas heating device 122 and the actual water temperature. As shown in fig. 4, it can be understood that when the actual water temperature of the water device is high, the heating efficiency of the air-source heat pump 112 is reduced, and the cost thereof is increased. Therefore, further, according to the ambient temperature and/or the usage state of the water-using device, one of the air-source heat pump 112 and the gas heating device 122 is selectively turned on to perform heating or perform heating together, and specifically, the method further includes:
when the ambient temperature is not lower than the first preset temperature and the set temperature of the water using device is higher than the second preset temperature, one of the air-source heat pump 112 and the gas heating device 122 is selected to be started for heating according to the actual water temperature of the water using device. Specifically, when the actual water temperature of the water using device is not greater than the second preset temperature, only the air-source heat pump 112 is turned on to perform heating; when the actual water temperature of the water using device is higher than the second preset temperature, only the gas heating device 122 is turned on for heating. The reason is that when the actual water temperature of the water using device is greater than the second preset temperature, the heating cost of the air-source heat pump 112 is already higher than that of the gas heating device 122. Therefore, the selection of the air-source heat pump 112 or the gas heating device 122 is determined by the actual water temperature of the water using device, and the energy saving effect can be achieved.
In an alternative embodiment, one of the air-source heat pump 112 and the gas heating device 122 is selectively turned on to perform heating or perform heating together according to the ambient temperature and/or the usage state of the water using device, and the method further includes:
and when the ambient temperature is lower than the first preset temperature, only starting the gas heating device for heating.
Taking the heating system 010 of the embodiment of the present application as an example, if the ambient temperature fed back by the third thermometer 150 is too low, the cost of the air-source heat pump 112 is high, and therefore the controller 160 turns on the second water pump 126 and turns on the gas heating device 122 to heat.
Further, the control method further comprises: and when the actual water temperature of the water using device reaches the set temperature, the air energy heat pump and the gas heating device are closed. When the water meets the requirements of users, the heating is stopped, thus avoiding the energy waste.
The above is the case where the floor heating 132 or the hot water storage tank 142 is used alone. In the present embodiment, when one of the warm air 132 and the hot water storage tank 142 is used, one of the air-energy heat pump 112 and the gas heating apparatus 122 is selected to be turned on for heating, depending on the ambient temperature and the state of use of the water-using device being used. When the floor heating 132 and the hot water storage tank 142 are used simultaneously, the air-source heat pump 112 and the gas heating device 122 are turned on to heat together. Since the floor heating 132 and the hot water storage tank 142 are simultaneously turned on, a higher heating power is required for heating, and in this case, the controller 160 controls the first water pump 116, the second water pump 126, the air-energy heat pump 112, and the gas heating device 122 to be simultaneously turned on.
Further, when the actual water temperature of the floor heating 132 reaches its set temperature, the controller 160 controls the first electromagnetic valve 131 to close; when the actual water temperature of the hot water storage tank 142 reaches its set temperature, the controller 160 controls the second electromagnetic valve 141 to be closed. Therefore, the water consumption device which reaches the set temperature can be prevented from separating heat, and the heating speed of the water consumption device which does not reach the set temperature is increased.
In summary, the heating system and the control method thereof according to the embodiments of the present application can selectively turn on one of the air-source heat pump and the gas heating device to perform heating or perform heating together according to the ambient temperature and/or the usage state of the water using device. By the control strategy, the heating strategy can be conveniently adjusted according to the ambient temperature or the using state of the water using device, so that a more energy-saving mode is selected, or a mode more meeting the requirements of users is selected. By flexibly selecting the heating mode, the cost can be saved or the user experience can be improved.
Although the present application is disclosed above, the present application is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present disclosure, and it is intended that the scope of the present disclosure be defined by the appended claims.
