fig. 1 is an application scenario diagram of the intelligent defrosting control method according to the embodiment of the present invention, and the intelligent defrosting control method according to the embodiment of the present invention can be applied to an application scenario of intelligent defrosting of an air-source heat pump. Specifically, as shown in fig. 1, the main execution body of the method provided by the present embodiment may be an air-energy heat pump, and the air-energy 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 and respectively provides high-temperature hot water for the water supply loop and the heating loop, and useful water points, such as kitchen water points and bathroom water points, are connected to the water supply loop; the heating circuit is connected with a floor heating pipeline for indoor heating. Because the air energy heat pump is in the heating process, one side of the main machine needs to discharge cooling air to the outside, and the frosting phenomenon can occur after the air energy heat pump is used for a long time.
In the prior art, after the air energy heat pump detects that the host machine frosts, the air energy heat pump can automatically defrost. However, the heat exchanger fins in the air energy heat pump host need to be heated in the defrosting process, according to the carnot cycle principle, hot water in the water return pipe of the air energy heat pump is used as a heat source to defrost the heat exchanger fins, so that the water temperature of the water outlet of the air energy heat pump is reduced, usually, in order to maintain indoor stable heat supply, the hot water in the heat supply loop needs to be continuously and circularly supplied, and after the water temperature of the water outlet of the air energy heat pump is reduced, the water temperature in the heat supply loop can be directly reduced, so that the indoor temperature is reduced, and the heating quality is affected.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated 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 defrost control method according to an embodiment of the present invention, which is applied to an air-source heat pump, where the air-source heat pump is respectively connected to a water supply loop and a heating loop, and as shown in fig. 2, the intelligent defrost control method according to this embodiment includes the following steps:
and S101, when the condition that the air energy heat pump meets the defrosting condition is detected, 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 fins is arranged in the air-source heat pump, and whether the air-source heat pump needs defrosting or not, that is, whether the air-source heat pump meets defrosting conditions or not can be determined by detecting the heat exchange fins through the sensor. More specifically, for example, a sensor for detecting frost formation on the plate, such as an ice formation sensor. Or, an image sensor, an air pressure sensor, or the like may be used, and whether the air-source heat pump meets the defrosting condition is determined by acquiring image or air pressure information and using a preset detection algorithm, where a specific implementation method for detecting that the air-source heat pump meets the defrosting condition is not illustrated.
Further, when the air energy heat pump is detected to meet the defrosting condition, the heat exchange sheets need to be melted and defrosted. And determining a water supply loop for providing a heat source for the defrosting process, namely a target water supply loop according to preset configuration parameters. The configuration parameters may be preset by a user, and include a target water supply circuit identifier, where the target water supply circuit identifier is used to indicate a water supply circuit that is turned on when the defrosting function is started, for example, the 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 a water supply circuit in which a bathroom water spot is located. In a possible implementation manner, the target water supply loop can be determined by the air energy heat pump directly through the target water supply loop identifier in the configuration parameters preset by the user, so that a heat source is provided for the defrosting process through the target water supply loop in the subsequent step.
And step S102, closing at least one heating loop and keeping the opening state of the target water supply loop.
For example, after the target water supply circuit is determined, the target water supply circuit is maintained in an open state and part or all of the heating circuit is closed by controlling opening and closing of solenoid valves provided at ports of the respective water supply circuit and heating circuit. At the moment, the flowing water output by the air energy heat pump cannot enter the closed heat supply loop, so that the influence of low-temperature water output by the air energy heat pump entering the heat supply loop on the room temperature after the subsequent defrosting function is started is avoided.
In a possible implementation manner, the configuration parameters further include a target heating loop identifier, and the target heating loop identifier is used for indicating a heating loop that is closed when the defrosting function is started; and after determining the target heating loop identification through the configuration parameters, closing the corresponding heating loop based on the target heating loop 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, and as shown in fig. 3, before the air-source heat pump starts the defrosting function, a target water supply circuit identifier and a target heating circuit identifier determined according to configuration parameters are controlled to turn on and off an electromagnetic valve, so that the heating circuit a, the heating circuit B, and the heating circuit C corresponding to the target heating circuit identifier are all turned off, and at the same time, 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 output from the air-source water heater circulates only through the water supply circuit a and the water supply circuit B, and does not pass through the heating circuit a, the heating circuit B, and the heating circuit C.
And step S103, starting a defrosting function of the air-source heat pump at a preset time so that the air-source heat pump can defrost through the heat source provided by the target water supply loop.
For example, after the on states of the heating circuit and the water supply circuit are set, the defrost function is activated at a preset time, for example, a time set by a user to not use hot water. Specifically, according to the carnot cycle principle, after the defrosting function is started, the air-source heat pump heats the heat exchange plate to melt frost condensed on the heat exchange plate, and simultaneously outputs water flow with a lower temperature after heat exchange, and the output water flow enters the water supply loop to reduce the temperature of water in the water supply loop, and at the moment, if a water using point on the water supply loop is opened, water with a lower temperature can be output. However, since the temperature of the hot water supplied from the warm water circuit varies unlike the heating circuit, the user perception is not triggered in the case where the user does not use the hot water. Therefore, by defrosting at a preset time, that is, at a time point when a user does not use hot water, cold water generated by defrosting is introduced into the water supply circuit, thereby avoiding influence on the heat supply circuit, improving stability of heat supply temperature, and improving heat supply finger quality.
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 a target water supply loop; and starting the defrosting function of the air-source heat pump at a preset moment so that the air-source heat pump defrosts through the 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 influenced due to the reduction of the room temperature caused by the change of the outlet water temperature of the air energy heat pump is solved, and the heating stability and the heating effect of the air energy heat pump are improved.
Fig. 4 is a flowchart of an intelligent defrost control method according to another embodiment of the present invention, and as shown in fig. 4, steps S101 to S102 of the intelligent defrost control method according to the embodiment shown in fig. 2 are further detailed, and a step of restarting a heating circuit after defrosting is finished is added, so that the intelligent defrost control method according to the embodiment includes the following steps:
step S201, when it is detected that the air energy heat pump meets the defrosting condition, configuration information is obtained, wherein the configuration information comprises cold water time information, and the cold water time information is used for representing time periods which do not need to supply hot water and correspond to each water supply loop.
Step S202, obtaining 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 currently.
And step S203, determining a target water supply loop according to the target water supply loop identifier, wherein the target water supply loop comprises at least two water supply loops.
Illustratively, the cold water time information is information for characterizing a time period during which each water supply circuit does not need to supply hot water, wherein the water supply circuit 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 needs or can be automatically generated by the air energy heat pump based on a water consumption record of the user. Through cold water time information, the water using habit of the user can be determined, so that the water using time period of the user is avoided in a targeted manner, and the problem that the water using comfort level of the user is influenced due to the fact that the outlet water temperature is too low in the defrosting process is avoided. Specifically, after the current system time is obtained, the identification of the water supply loop corresponding to the water outlet point of the user's no-water demand in the current time period and the identification of the target water supply loop are determined according to the cold water time information in the configuration information. For example, the current system time is 12:00 am. According to the cold water time information, at the current time, the corresponding water supply circuit is marked as #1 and the corresponding water supply circuit is marked as #2, and the water supply circuit is marked as #1 and the corresponding water supply circuit is marked as #2, so that the water supply circuit which does not need to supply hot water currently is represented. More specifically, for example, the water supply circuit is identified as #1 corresponding to the water supply circuit in which the water spot for bathroom a is located; the water supply circuit is identified as #2 corresponding to the water supply circuit in which the water usage point of bathroom B is located. Further, the water supply circuit identification # 1 and the water supply circuit identification # 2 are determined as the target water supply circuit identification.
And step S204, acquiring 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 larger than the corresponding water temperature parameter, the opening state of the water supply loop is kept; and when the real-time water temperature of the water supply loop in the target water supply loop is less than or equal to the corresponding water temperature parameter, closing the water supply loop until the rest of the water supply loops in the target water supply loop are in an open state.
In an exemplary embodiment, the configuration parameters further include a water temperature parameter corresponding to the water supply circuit identifier, and the water temperature parameter is used for representing the lowest opening temperature of the water supply circuit. Fig. 5 is a schematic diagram of a configuration parameter according to an embodiment of the present invention, and the following describes steps of this embodiment with reference to fig. 5. As shown in fig. 5, each row in the configuration parameters corresponds to an identifier of a water supply circuit, i.e., a water supply circuit identifier; each water supply loop identification corresponds to a water temperature parameter and cold water time information. Specifically, for example, the identifier # 1 of the water supply circuit corresponds to a water temperature parameter of 10 degrees celsius; the corresponding cold water time information is 22:00-06:00 (22 pm to 6 am), the identifier # 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 (from 9 am to 18 pm); the identifier # 3 of the water supply loop corresponds to a 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 in the configuration parameters and the current system time (for example, 14:00), the #2 and the #3 are determined as the target water supply circuit identifications, that is, the water supply circuit corresponding to the #2 and the water supply circuit corresponding to the #3 are determined as the target water supply circuits. Further, acquiring real-time water temperatures of all water supply loops 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 a water temperature parameter (10 ℃) corresponding to #2 with a water temperature parameter (5 ℃) corresponding to #3, and if the real-time water temperature of the water supply loop is greater than the water temperature parameter, opening the water supply loop to continue serving as a heat source for heating in a defrosting process, and simultaneously reducing the temperature; if the real-time water temperature of the water supply loop is not larger than the water temperature parameter, the water supply loop is closed and is not used as a heat source for heating in the defrosting process any more, so that the problem that the water temperature is too low to influence the water using comfort level of a user when the temperature continues to drop and a random water using event of the user occurs is avoided. Fig. 6 is a schematic diagram of closing a water supply loop according to an embodiment of the present invention, as shown in fig. 6, when the real-time water temperature of the water supply loop # 2 is 20 degrees celsius and the real-time water temperature of the water supply loop # 3 is 20 degrees celsius, the water supply loop # 2 and the water supply loop # 3 are kept open; as the defrosting process proceeds, the water temperature of each water supply loop in the target water supply loop continues to decrease, and when the real-time water temperature of the water supply loop # 2 is 10 degrees celsius and the real-time water temperature of the water supply loop # 3 is 12 degrees celsius, the real-time water temperature of the water supply loop # 2 is equal to the corresponding water temperature parameter (10 degrees celsius), at this time, the water supply loop # 2 is closed, and the water supply loop # 3 continues to be kept in an open state, so as to provide a heat source for the defrosting process.
In the embodiment, the water supply loops are closed through the water temperature parameters of the water supply loops in the target water supply loop when the water temperature of the water supply loop is reduced to be lower than the water temperature parameter, so that the temperature drop balance of the water supply loops is realized, the water temperature of each water supply loop does not have extreme low temperature lower than the water temperature parameter even in the defrosting process, and the water use comfort level of a user is improved.
Meanwhile, under the condition that the water temperatures of the water supply loops reach the water temperature parameter but 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.
And S206, acquiring room temperature information corresponding to each heating loop, wherein the room temperature information represents the indoor temperature in the room corresponding to the heating loop.
And step S207, determining a heating loop corresponding to the indoor temperature smaller than the preset room temperature threshold as a target heating loop according to the room temperature information, and closing the target heating loop.
For example, in one possible implementation, all heating circuits may be turned off before the defrosting process is started, so as to ensure that the temperature of the room corresponding to all heating circuits does not receive the influence of the defrosting process and generate temperature fluctuation. In another possible implementation manner, only part of the heat supply loops are closed, and part of the heat supply loops are kept in an open state to provide a heat source for the defrosting process so as to improve the defrosting efficiency. Specifically, room temperature information representing the indoor temperature corresponding to each heating loop is obtained, and if the indoor temperature is less than or equal to a preset room temperature threshold, it is indicated that the current room temperature of the room just reaches the preset temperature or is lower, and a heat source should not be provided for the defrosting process, so that the heating loop corresponding to the room with the indoor temperature less than the preset room temperature threshold is determined as a target heating loop and is closed in the subsequent defrosting process; on the contrary, if the indoor temperature is greater than the preset room temperature threshold value, it is indicated that the room temperature of the current room is higher, and redundant heat is provided for a heat source in the defrosting process, so that the heating loop corresponding to the room with the indoor temperature greater than the preset room temperature threshold value is set to be in an open state in the subsequent defrosting process, a heat source is provided for the defrosting process, and the defrosting efficiency is improved.
And step S208, starting the defrosting function of the air-source heat pump at a preset time so that the air-source heat pump defrosts through the heat source provided by the target water supply loop.
And step S209, after the defrosting function is finished, if the outlet water temperature of the air energy heat pump is higher than the preset outlet water temperature, the closed target heating loop is opened.
For example, after the defrosting function is finished, the air-source heat pump is switched to a normal heating mode, that is, low-temperature water input by the water return pipe and the water inlet pipe is heated, and high-temperature water is output from the water outlet to the heating loop for indoor heating. Since the temperature of the water flow output by the air-source heat pump is still low immediately after defrosting is finished, and since the temperature of the water inside the heating loop is kept at a high temperature after the heating loop is closed, the temperature of the water output by the air-source heat pump needs to be detected first, and when the preset temperature of the water output is reached, the closed target heating loop is opened, and high-temperature water is input into the target heating loop, so that continuous and stable heating is realized, and fluctuation of indoor heating temperature is avoided.
In this embodiment, the implementation manners of step S201 and step S208 are the same as the implementation manners of step S101 and step S103 in the embodiment shown in fig. 2 of the present invention, and are not described again.
