fig. 1 is an application scenario diagram of an intelligent defrosting control method provided by an embodiment of the present invention, where the intelligent defrosting control method provided by the embodiment may be applied to an application scenario of intelligent defrosting of an air-source heat pump. Specifically, as shown in fig. 1, the execution body of the method provided in this embodiment may be an air-source heat pump, and the air-source heat pump is connected to the water supply circuit and the heating circuit respectively. The air energy heat pump outputs hot water through a heat pump water outlet, the heat pump water outlet is respectively communicated with water inlets of the water supply loop and the heating loop, high-temperature hot water is respectively provided for the water supply loop and the heating loop, and water points, such as a kitchen water point and a bathroom water point, are connected to the water supply loop; the heating circuit is connected to, for example, a floor heating pipe for indoor heating. Because the air energy heat pump is used in the heating process, the cooling air is required to be discharged to the outside of the host machine side, and the frosting phenomenon can occur after the air energy heat pump is used for a long time.
In the prior art, after detecting that a host computer frosts, an air energy heat pump automatically performs defrosting. However, in the defrosting process, the heat exchange plates in the air energy heat pump host are required to be heated, and according to the principle of Carnot cycle, the hot water of the return pipe of the air energy heat pump is used as a heat source to defrost the heat exchange plates, so that the water temperature of the water outlet of the air energy heat pump is reduced, and in order to keep stable heat supply in a room, the hot water in the heat supply loop is required to be continuously and circularly supplied, and when the water temperature of the water outlet of the air energy heat pump is reduced, the water temperature in the heat supply loop is directly reduced, so that the indoor temperature is reduced, and the heating quality is affected.
The following describes the technical scheme of the present invention and how the technical scheme of the present invention solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of an intelligent defrosting control method according to an embodiment of the present invention, which is applied to an air-source heat pump, wherein the air-source heat pump is respectively connected with a water supply loop and a heating loop, and as shown in fig. 2, the intelligent defrosting control method according to the embodiment includes the following steps:
step S101, when the air energy heat pump is detected to meet the defrosting condition, determining a target water supply loop according to preset configuration parameters, wherein the target water supply loop is used for providing a heat source for the defrosting function of the air energy heat pump.
Illustratively, a sensor for detecting frosting of the heat exchange plates is arranged in the air energy heat pump, and whether the air energy heat pump needs defrosting or not, that is, whether the air energy heat pump meets the defrosting condition or not can be determined by detecting the heat exchange plates through the sensor. More specifically, for example, a sensor for detecting frosting of the heat exchanger plates, such as an icing sensor. Or, the method can also be an image sensor, an air pressure sensor and the like, and whether the air energy heat pump meets the defrosting condition is judged through a preset detection algorithm by collecting the image or the air pressure information, so that a specific implementation method for detecting that the air energy heat pump meets the defrosting condition is not exemplified one by one.
Further, when it is detected that the air-source heat pump satisfies the defrosting condition, the heat exchange plates need to be melted and defrosted. According to preset configuration parameters, a water supply loop for providing a heat source for the defrosting process, namely a target water supply loop, is determined. The configuration parameters may be preset by the user, and the configuration parameters include a target water supply circuit identifier, where the target water supply circuit identifier is used to indicate a water supply circuit opened when the defrosting function is started, for example, a target water supply circuit identifier #01 indicates a water supply circuit where a kitchen water point is located; target water supply circuit identification #02 indicates the water supply circuit in which the bathroom water spot is located. In one possible implementation, the air-source heat pump can determine the target water supply circuit directly through the target water supply circuit identification within the configuration parameters preset by the user, so as to provide a heat source for the defrosting process through the target water supply circuit in the subsequent step.
Step S102, closing at least one heating loop and keeping the opening state of the target water supply loop.
Illustratively, after the target water supply circuit is determined, a part or all of the heating circuit is closed by controlling the opening and closing of solenoid valves provided at ports of the respective water supply circuit and heating circuit to maintain the target water supply circuit in an open state. At this time, flowing water output by the air energy heat pump cannot enter the closed heating loop, so that the influence of low-temperature water output by the air energy heat pump on the room temperature caused by entering the heating loop after the follow-up defrosting function is started is avoided.
Wherein, in one possible implementation, the configuration parameters further include a target heating circuit identifier, where the target heating circuit identifier is used to indicate a heating circuit that is closed when the defrosting function is started; and after the target heating circuit identification is determined through the configuration parameters, closing the corresponding heating circuit based on the target heating circuit identification.
Fig. 3 is a schematic diagram of controlling a heating circuit and a water supply circuit according to an embodiment of the present invention, as shown in fig. 3, before the defrosting function is started by the air-source heat pump, a target water supply circuit identifier and a target heating circuit identifier determined according to configuration parameters are turned on and off, and the heating circuit a, the heating circuit B and the heating circuit C corresponding to the target heating circuit identifier are all turned off by controlling the opening and closing of the electromagnetic valve, and meanwhile, the water supply circuit a and the water supply circuit B corresponding to the target water supply circuit identifier are kept on. At this time, the water flow outputted from the air-energy water heater will circulate only through the water supply circuit a and the water supply circuit B, and not through the heating circuit a, the heating circuit B, and the heating circuit C.
Step S103, starting a defrosting function of the air energy heat pump at a preset time so that the air energy heat pump can defrost through a heat source provided by the target water supply loop.
The defrosting function is started, for example, at a preset time, for example, a time set by the user when hot water is not used, after the open states of the heating circuit and the water supply circuit are set. Specifically, according to the carnot cycle principle, after the defrosting function is started, the air energy heat pump can heat the heat exchange plates, melt frosting condensed on the heat exchange plates, meanwhile, output water flow with lower temperature after heat exchange, and the output water flow enters the water supply loop to reduce the water temperature in the water supply loop, and at the moment, if a water consumption point on the water supply loop is opened, the water with lower temperature is output. However, since the temperature of the hot water provided by the warm water circuit varies, unlike the effect of the heating circuit, the user's perception is not triggered in the case where the user does not use the hot water. Therefore, by defrosting at a preset moment, namely at a time point when a user does not use hot water, cold water generated by defrosting is introduced into the water supply loop, so that the influence on the heat supply loop is avoided, the stability of the heat supply temperature is improved, and the heat supply finger quality is improved.
In the embodiment, when the air energy heat pump is detected to meet the defrosting condition, a target water supply loop is determined according to preset configuration parameters, wherein the target water supply loop is used for providing a heat source for the defrosting function of the air energy heat pump; closing at least one heating loop and keeping the opening state of the target water supply loop; and starting the defrosting function of the air energy heat pump at a preset moment so that the air energy heat pump can defrost through a heat source provided by the target water supply loop. Because the heating loop is closed in the defrosting process and the water supply loop is used as a heat source for defrosting, the problem that the indoor heating quality is affected due to the reduction of the room temperature caused by the change of the outlet water temperature of the air energy heat pump is avoided, and the heating stability and the heating effect of the air energy heat pump are improved.
Fig. 4 is a flowchart of an intelligent defrosting control method according to another embodiment of the present invention, and as shown in fig. 4, the intelligent defrosting control method according to this embodiment further refines steps S101 to S102 on the basis of the intelligent defrosting control method according to the embodiment shown in fig. 2, and adds a step of restarting a heating circuit after defrosting is completed, and the intelligent defrosting control method according to this embodiment includes the following steps:
in step S201, when it is detected that the air-source heat pump satisfies the defrosting condition, configuration information is acquired, where the configuration information includes cold water time information, and the cold water time information is used to characterize a time period corresponding to each water supply loop and requiring no hot water.
Step S202, acquiring the current system time, and determining a target water supply loop identifier according to the system time and the cold water time information, wherein the target water supply loop identifier indicates a water supply loop which does not need to supply hot water at present.
Step S203, determining a target water supply loop according to the target water supply loop identification, wherein the target water supply loop comprises at least two water supply loops.
The cold water time information is information for representing a time period when each water supply loop does not need to supply hot water, wherein the water supply loop corresponds to at least one water consumption point, such as a kitchen water consumption point and a bathroom water consumption point, and the cold water time information can be manually set by a user according to requirements or can be automatically generated by an air energy heat pump based on water consumption records of the user. Through cold water time information, can confirm user's water habit to the pointed water period of avoiding the user avoids the water temperature that the defrosting process caused to be too low, influences user's water comfort level. Specifically, after the current system time is obtained, determining the identification of the water supply loop corresponding to the water outlet point of the user without water demand in the current period and the identification of the target water supply loop according to the cold water time information in the configuration information. For example, the current system time is 12:00 noon. According to the cold water time information, at the current time, the corresponding water supply circuit identification is #1 and the water supply circuit identification is #2, and the water supply circuit identification is #1 and the water supply circuit identification is #2 represent the water supply circuit which does not need to supply hot water at present. More specifically, for example, the water supply circuit is identified as #1 corresponding to the water supply circuit in which the bathroom A water spot is located; the water supply circuit is identified as #2 for the water supply circuit where the water point for bathroom B is located. Further, the water supply circuit identification #1 and the water supply circuit identification #2 are determined as target water supply circuit identifications.
Step S204, obtaining the real-time water temperature of each water supply loop in the target water supply loop.
Step S205, when the real-time water temperature of the water supply loop in the target water supply loop is greater than the corresponding water temperature parameter, the opening state of the water supply loop is maintained; when the real-time water temperature of the water supply loop in the target water supply loop is smaller than or equal to the corresponding water temperature parameter, the water supply loop is closed until one water supply loop remained in the target water supply loop is in an open state.
Illustratively, the configuration parameters further include a water temperature parameter corresponding to the water supply circuit identifier, wherein the water temperature parameter is used for representing the minimum opening temperature of the water supply circuit. Fig. 5 is a schematic diagram of a configuration parameter provided in an embodiment of the present invention, and the steps of the embodiment are described below with reference to fig. 5. As shown in fig. 5, each row in the configuration parameters corresponds to an identification of one water supply circuit, namely, a water supply circuit identification; each water supply loop identifier corresponds to a water temperature parameter and cold water time information. Specifically, for example, the label #1 of the water supply loop corresponds to a water temperature parameter of 10 ℃; the corresponding cold water time information is 22:00-06:00 (22 pm to 6 am), the mark #2 of the water supply loop corresponds to the water temperature parameter of 10 ℃; the corresponding cold water time information is 09:00-18:00 (9 in the morning to 18 in the evening); the mark #3 of the water supply loop corresponds to the water temperature parameter of 5 ℃; the corresponding cold water time information is 12:00-18:00 (12 am to 18 pm).
Illustratively, according to the cold water time information and the current system time (for example, 14:00) in the configuration parameters, determining #2 and #3 as target water supply loop identifications, namely, determining the water supply loop corresponding to #2 and the water supply loop corresponding to #3 as target water supply loops. Further, acquiring the real-time water temperature of each water supply loop in the target water supply loop through a temperature sensor, namely, the real-time water temperature of the water supply loop corresponding to #2 and the real-time water temperature of the water supply loop corresponding to #3, comparing the real-time water temperature with the water temperature parameter (10 ℃) corresponding to #2 and the water temperature parameter (5 ℃) corresponding to #3, opening the water supply loop if the real-time water temperature of the water supply loop is larger than the water temperature parameter, and continuously supplying heat as a heat source in the defrosting process, wherein the temperature is reduced; if the real-time water temperature of the water supply loop is not greater than the water temperature parameter, the water supply loop is closed, and the water supply loop is not used as a heat source for heating in the defrosting process, so that the problem that the water outlet temperature is too low and the water using comfort level of a user is affected when a random water using event of the user occurs is avoided. Fig. 6 is a schematic diagram of a closed water supply circuit according to an embodiment of the present invention, as shown in fig. 6, when the real-time water temperature of the water supply circuit #2 is 20 degrees celsius, and when the real-time water temperature of the water supply circuit #3 is 20 degrees celsius, the water supply circuit #2 and the water supply circuit #3 are kept open; as the defrosting process proceeds, the water temperature of each water supply circuit in the target water supply circuit continues to drop, when the real-time water temperature of the water supply circuit #2 is 10 degrees celsius, and when the real-time water temperature of the water supply circuit #3 is 12 degrees celsius, the real-time water temperature of the water supply circuit #2 is equal to the corresponding water temperature parameter (10 degrees celsius), at this time, the water supply circuit #2 is closed, and the water supply circuit #3 continues to keep in an open state, so as to provide a heat source for the defrosting process.
When the target water supply loop comprises a plurality of water supply loops, the distances between the water supply loops and the air energy heat pump are different, so that the temperature falling speeds of the water supply loops are different after the low temperature water input by the air energy heat pump is received, and the water temperature of the water supply loops gradually falls.
Meanwhile, under the condition that the water temperatures of the water supply loops reach the water temperature parameters and the defrosting process is not finished, one water supply loop is reserved, and a heat source is continuously provided for the defrosting process, so that the defrosting process can be normally finished.
Step S206, obtaining the room temperature information corresponding to each heating circuit, wherein the room temperature information represents the indoor temperature in the room corresponding to the heating circuit.
Step S207, according to the room temperature information, determining a heating loop corresponding to the indoor temperature smaller than the preset room temperature threshold as a target heating loop, and closing the target heating loop.
In one possible implementation, all heating circuits may be shut down before the defrosting process is started, to ensure that the temperatures of the rooms to which all heating circuits correspond are not affected by the defrosting process, resulting in temperature fluctuations. In another possible implementation, only a portion of the heating circuit is turned off, leaving a portion of the heating circuit in an on state, providing a heat source for the defrost process to increase defrost efficiency. Specifically, room temperature information representing the indoor temperature corresponding to each heating loop is obtained, if the indoor temperature is smaller than or equal to a preset room temperature threshold value, the fact that the room temperature of the room just reaches the preset temperature or is lower at present is indicated that a heat source is not needed to be provided for a defrosting process, and therefore the heating loop corresponding to the room with the indoor temperature smaller than the preset room temperature threshold value is determined to be a target heating loop and is closed in a subsequent defrosting process; otherwise, if the indoor temperature is greater than the preset room temperature threshold, the room temperature of the current room is higher, and redundant heat is provided for providing a heat source for the defrosting process, so that a heating loop corresponding to the room with the indoor temperature greater than the preset room temperature threshold is set to be in an on state in the subsequent defrosting process, the heat source is provided for the defrosting process, and the defrosting efficiency is improved.
Step S208, the defrosting function of the air energy heat pump is started at a preset time, so that the air energy heat pump is defrosted through a heat source provided by the target water supply loop.
Step S209, after the defrosting function is finished, if the outlet water temperature of the air-source heat pump is greater than the preset outlet water temperature, the closed target heating circuit is opened.
The air-source heat pump is switched to a normal heating operation mode, namely, low-temperature water input by the water return pipe and the water inlet pipe is heated, and high-temperature water is output to the heating loop from the water outlet for indoor heating after the defrosting function is finished. Because the water temperature of the water flow output by the air energy heat pump is still lower when defrosting is just finished, and because the water temperature inside the heating loop is kept higher after the heating loop is closed, the water outlet temperature of the air energy heat pump needs to be detected first, and when the water outlet temperature reaches the preset water outlet temperature, the closed target heating loop is opened again, high-temperature water is input into the target heating loop, continuous and stable heating is realized, and fluctuation of indoor heating temperature is avoided.
In this embodiment, the implementation manner of step S201 and step S208 is the same as the implementation manner of step S101 and step S103 in the embodiment shown in fig. 2 of the present invention, and will not be described in detail here.
