Referring to fig. 3, an embodiment of a control method of an air conditioner according to the present application is provided. In this embodiment, the control method of the air conditioner includes:
step S10, acquiring characteristic temperature related to the operation of the radiation module when the air conditioner is in a heating operation state;
in the heating operation process of the air conditioner, the heat pump module is started, the indoor heat exchanger is in a condensation state to release heat, the indoor heat exchanger heats indoor air through heat exchange, and in the process, the controllable radiation module is started to release heat synchronously with the indoor heat exchanger to heat the indoor air.
During the process of opening the radiation module, the characteristic temperature related to the operation of the radiation module can be obtained. The characteristic temperature is a temperature characteristic parameter that represents an operation condition or an operation requirement of the radiation module, and specifically may be a temperature parameter that represents a heating amount requirement of the radiation module (such as an indoor heat exchanger temperature and/or an indoor ambient temperature), and may also be a temperature parameter that represents an operation reliability of the radiation module (such as a radiation module temperature).
Here, the number of the acquired characteristic temperatures may be one, or may be more than one. For example, the indoor heat exchanger temperature, the indoor ambient temperature, and the radiation module temperature may be acquired as the characteristic temperatures, and a portion may be selected from the indoor heat exchanger temperature, the indoor ambient temperature, and the radiation module temperature as the characteristic temperatures.
Step S20, determining a control parameter of the radiation temperature of the radiation module according to the characteristic temperature;
the control parameter is in particular a target operating parameter of a temperature control element for increasing, decreasing or maintaining the radiation temperature of the radiation module. The temperature regulating component can be the radiation module itself, and can also be a heat radiation module corresponding to the radiation module. For example, the control parameters may include radiation power of the radiation module, an opening number of vents on the radiation module, heat dissipation power (e.g., fan speed, etc.) of a heat dissipation module corresponding to the radiation module, and/or opening parameters of the radiation module.
Different characteristic temperatures correspond to different control parameters. The corresponding relation between the characteristic temperature and the control parameter can be preset, and can be a mapping relation, a calculation relation and the like. And determining the control parameter corresponding to the current characteristic temperature based on the mapping relation. In this correspondence, in this embodiment, as the characteristic temperature increases, the target value of the radiation temperature of the radiation module corresponding to the control parameter tends to decrease. In other words, as the characteristic temperature decreases, the target value of the radiation temperature of the radiation module corresponding to the control parameter increases. In other embodiments, the variation relationship between the characteristic temperature and the radiation temperature corresponding to the control parameter may have other rules or no definite rule. For example, the smaller the indoor heat exchanger temperature, the radiation module temperature, or the indoor ambient temperature is, the greater the radiation power of the radiation module may be, and the greater the indoor heat exchanger temperature, the radiation module temperature, or the indoor ambient temperature is, the smaller the radiation power of the radiation module may be; the rotating speed of a fan corresponding to the radiation module can be smaller when the temperature of the radiation module is smaller, and the rotating speed of the fan corresponding to the radiation module can be larger when the temperature of the radiation module is larger; the opening number of the ventilation openings corresponding to the radiation modules can be increased when the temperature of the radiation modules is increased, and the opening number of the ventilation openings corresponding to the radiation modules can be decreased when the temperature of the radiation modules is decreased; the greater the indoor heat exchanger temperature or the indoor ambient temperature is, the smaller the opening number of the vents corresponding to the radiation modules may be, and the smaller the indoor heat exchanger temperature or the indoor ambient temperature is, the greater the opening number of the vents corresponding to the radiation modules may be.
And S30, controlling the radiation module and/or the heat dissipation module corresponding to the radiation module to operate according to the control parameters.
When the control parameter includes an operation parameter such as radiation power of the radiation module, the radiation module may be controlled to operate at the radiation power, so as to adjust the radiation temperature of the radiation module by adjusting the input of the radiation module itself, for example, the radiation module is controlled to use a voltage corresponding to the radiation power as an input voltage of the radiation module.
When the control parameters comprise the heat dissipation parameters of the heat dissipation module corresponding to the radiation module, the heat dissipation module can be controlled to operate according to the heat dissipation parameters, so that the radiation temperature of the radiation module can be adjusted by adjusting the heat dissipation efficiency of the radiation module. In this embodiment, the heat dissipation module includes a fan, and if the radiation module is disposed in the air duct, the heat dissipation module is a fan disposed in the inner chamber of the air duct. In other embodiments, the heat dissipation module may also be any other type of heat dissipation element, and specifically, the heat dissipation module may further include a heat dissipation pipeline in heat exchange connection with the heat dissipation module, for example, a pipeline for introducing cold water.
Specifically, when the control parameter includes reducing the operating power of the radiation module, the radiation module can be controlled to reduce the input voltage; when the control parameters comprise the rotating speed of the cooling fan corresponding to the radiation module, the fan can be controlled to increase the current rotating speed; the control parameters include that when the radiation module is closed, the radiation module can be controlled to be closed, and the radiation wave is stopped being released to stop heating the indoor air.
The control method of the air conditioner provided by the embodiment of the invention is based on the air conditioner provided with the radiation module for releasing radiation waves to heat indoor air, the radiation module can be started in the heating process of the air conditioner, the heating capacity of the air conditioner can be improved, and the heating efficiency of the air conditioner to the indoor environment can be improved.
Further, based on the above embodiments, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, the characteristic temperature includes a radiation module temperature of the radiation module, an indoor heat exchanger temperature of the air conditioner or an indoor environment temperature, the heat dissipation module includes a fan, specifically, when the radiation module is disposed in the air duct, the fan herein refers to an indoor fan in the air duct, an operation parameter of the indoor fan may affect a magnitude of a heat dissipation amount of the radiation module, wherein the larger a rotation speed of the indoor fan is, the larger a heat dissipation amount of the radiation module is, and the smaller a rotation speed of the indoor fan is, the smaller a heat dissipation amount of the radiation module is.
In one case, when the characteristic temperature includes a radiation module temperature, the step S20 includes:
step S21, when the temperature of the radiation module is greater than or equal to a first preset temperature, determining the control parameter to comprise at least one of reducing the operating power of the radiation module, increasing the rotating speed of the fan and turning off the radiation module; and when the rotating speed of the fan is increased, the heat dissipation capacity of the radiation module is increased.
The radiation module temperature is obtained by acquiring temperature data detected by a temperature sensor arranged on the surface of the radiation module.
The first preset temperature corresponding to the temperature of the radiation module is a critical value of the surface temperature of the radiation module for distinguishing whether the radiation module is safely operated. The first preset temperature may be a fixed temperature configured by default in the system, or may be a temperature selected from a plurality of preset temperatures based on a maximum rotation speed of the fan currently allowed to operate and/or a current indoor ambient temperature.
The power adjustment parameter when the power is reduced or the rotation speed adjustment parameter when the rotation speed of the fan is increased may be a preset fixed parameter, or may be a parameter determined based on a temperature difference between the temperature of the radiation module and the first preset temperature.
The temperature of the radiation module is greater than or equal to the first preset temperature, which indicates that the current operation of the radiation module has safety risk, at the moment, the radiation temperature of the radiation module is reduced by reducing the operation power or closing the radiation module so as to reduce the output radiation heat, or the rotating speed of the fan can be increased so as to increase the heat dissipation capacity of the radiation module, so that the radiation module is prevented from being damaged due to overhigh temperature, the reliable operation of the radiation module is ensured, and the service life of the radiation module is prolonged. The temperature of the radiation module is lower than the first preset temperature, which indicates that the radiation module is currently in a safe operation state, and at this time, the radiation module or the corresponding heat dissipation module can maintain the current state to operate or can be controlled based on other parameters without limitation, such as increase of radiation power of the radiation module or reduction of rotation speed of a fan.
Further, step S21 may include: when the temperature of the radiation module is greater than or equal to the first preset temperature and the temperature of the radiation module is less than a second preset temperature, determining the control parameter as reducing the operating power of the radiation module and/or increasing the rotating speed of the fan; when the temperature of the radiation module is greater than or equal to the second preset temperature, determining that the control parameter is to close the radiation module; wherein the second preset temperature is greater than the first preset temperature.
The second preset temperature is specifically a critical value of the surface temperature of the radiation module for distinguishing the high and low operational safety risks of the radiation module.
When the temperature of the radiation module is greater than or equal to the first preset temperature and the temperature of the radiation module is less than the second preset temperature, the installation position of the radiation module can be obtained, and when the installation position of the radiation module is located outside the air duct, the control parameter can be determined to reduce the operation power of the radiation module; when the mounting position of the radiation module is located in the air duct, the control parameter can be determined to increase the rotation speed of the fan.
Specifically, when the temperature of the radiation module is greater than or equal to the second preset temperature, the operation of the radiation module is indicated to be in a high risk, the radiation module is turned off at the moment, the temperature of the radiation module can be reduced at a very high speed, safety accidents can not occur in the operation of the radiation module, and the operation safety of the air conditioner is improved while the service life of the radiation module is ensured. And when the temperature of the radiation module is greater than or equal to the first preset temperature and lower than the second preset temperature, the operation safety risk of the radiation module is lower, the rotating speed of the fan is increased or the power of the radiation module is reduced, heat output from the radiation module to the indoor environment is favorably maintained, and the service life of the radiation module is prolonged while the heating efficiency of the air conditioner is improved.
In another case, when the characteristic temperature includes an indoor heat exchanger temperature, the step S20 includes:
and S22, when the temperature of the indoor heat exchanger is greater than or equal to a third preset temperature, determining the control parameter to comprise reducing the operating power of the radiation module or closing the radiation module.
The temperature of the indoor heat exchanger is obtained by acquiring temperature data detected by a temperature sensor arranged on the coil pipe of the indoor heat exchanger.
The third preset temperature corresponding to the temperature of the indoor heat exchanger is a critical value used for distinguishing whether the heat exchange amount (which can be represented by the change value of the indoor environment temperature in unit time) output by the indoor heat exchanger is large enough. The third preset temperature may be a fixed temperature configured by default in the system, or may be a temperature selected from a plurality of preset temperatures based on the current operating speed of the indoor fan and/or the temperature difference between the current outlet air temperature and the target outlet air temperature.
The power adjustment parameter during power reduction may be a preset fixed parameter, or a parameter determined based on a temperature difference between the temperature of the indoor heat exchanger and a third preset temperature.
The temperature of the indoor heat exchanger is greater than or equal to the third preset temperature, which indicates that the heat output by the indoor heat exchanger is enough, at the moment, the operating power is reduced or the radiation module is turned off to reduce the radiation heat output by the radiation module, so that the heating efficiency of the air conditioner is ensured, and the energy consumption of the radiation module is saved. And the temperature of the indoor heat exchanger is lower than the third preset temperature, which indicates that the heat output by the indoor heat exchanger is insufficient, and at the moment, the radiation module can maintain the current state to operate or improve the output power, thereby being beneficial to ensuring the effective improvement of the heating efficiency of the air conditioner.
Further, step S22 includes: when the temperature of the indoor heat exchanger is greater than or equal to a third preset temperature and the temperature of the indoor heat exchanger is less than a fourth preset temperature, determining the control parameter as reducing the operating power of the radiation module; when the temperature of the indoor heat exchanger is greater than or equal to the fourth preset temperature, determining that the control parameter is to close the radiation module; wherein the fourth preset temperature is greater than the third preset temperature.
The fourth preset temperature is specifically a temperature critical value of the indoor heat exchanger for distinguishing whether the heat pump cycle system in which the indoor heat exchanger is located has a reliability risk.
The power adjustment parameter in the process of reducing the operating power can be determined according to the exhaust temperature of the compressor of the heat pump module where the indoor heat exchanger is located, different exhaust temperatures correspond to different power adjustment parameters, and the radiation module can be controlled to reduce the operating power according to the determined power adjustment parameter.
Specifically, when the temperature of the indoor heat exchanger is greater than or equal to the fourth preset temperature, the heat pump circulating system where the indoor heat exchanger is located has reliability, the radiation module is turned off at the moment, the radiation temperature of the radiation module can be rapidly reduced, the system pressure of the heat pump circulating system is ensured not to be too high, the reliable operation of the heat pump circulating system is ensured, and the heat pump circulating system is ensured to stably output heat to indoor air. When the temperature of the indoor heat exchanger reaches the third preset temperature and is lower than the fourth preset temperature, the fact that the heat output by the indoor heat exchanger is sufficient currently is shown, the heat pump system where the indoor heat exchanger is located is in a reliable operation state, the operation power of the radiation module is reduced at the moment, the energy consumption of the radiation module is saved, the problem of reliability of the heat pump system is solved, and the heat pump system where the indoor heat exchanger is located can exchange heat for indoor air with high energy efficiency.
In still another case, when the characteristic temperature includes an indoor ambient temperature, the step S20 includes:
and S23, when the indoor environment temperature is greater than or equal to a fifth preset temperature, determining the control parameter to comprise reducing the operating power of the radiation module or closing the radiation module.
The indoor environment temperature can be obtained by acquiring temperature data detected by a temperature sensor arranged in the indoor environment.
The fifth preset temperature corresponding to the indoor environment temperature is specifically a temperature critical value for distinguishing whether the indoor environment can make the user feel the cold feeling of the indoor environment. The fifth preset temperature may be a fixed temperature configured by default in the system, or may be a temperature selected from a plurality of preset temperatures based on the current operating speed of the fan, the current temperature of the indoor heat exchanger, and/or the current temperature of the radiation module.
The power adjustment parameter during power reduction may be a preset fixed parameter, or a parameter determined based on a temperature difference between the indoor ambient temperature and a fifth preset temperature.
The indoor environment temperature is greater than or equal to the fifth preset temperature, which indicates that the temperature of the current indoor environment is higher, so that a user cannot feel cold, and at the moment, the temperature of the radiation module is reduced by reducing the running power or closing the radiation module so as to reduce the output radiation heat and effectively save the energy consumption of the air conditioner. And the indoor environment temperature is less than the fifth preset temperature, which indicates that the current indoor environment temperature is low and is easy to cause a user to feel cold, and at the moment, the radiation module is kept at the current state and is started or can increase the operation power, so that the heating efficiency of the air conditioner is effectively improved, and the indoor environment of the air conditioner under heating can quickly reach the comfortable temperature of the user.
Further, in the present embodiment, step S23 includes: when the indoor environment temperature is greater than or equal to the fifth preset temperature, acquiring a target state of heating operation of the air conditioner; the target state comprises a state which is required to be reached by target heating quantity or target operation noise when the air conditioner is in heating operation; when the target state is a state other than the first state and the second state, performing the step of determining the control parameter includes reducing the operating power of the radiation module or turning off the radiation module; the first state is that the target heating capacity is larger than a set heating capacity or the current heating capacity of the air conditioner, and the second state is that the target running noise is smaller than a set noise threshold or the current running noise of the air conditioner.
The target state can be determined by acquiring instructions input by a user or monitoring scenes in the current air conditioner acting space. For example, when a first command indicating that heating is prioritized is input by a user, the target state may be determined to be the first state (i.e., the target heating amount is greater than the set heating amount or the current heating amount of the air conditioner), when a second command indicating that muting is prioritized is input by the user, the target state may be determined to be the second state (i.e., the target operation noise is less than the set noise threshold or the current operation noise of the air conditioner), and if the first command or the second command input by the user does not exist, the target state may be determined to be a state other than the first state and the second state. Or, obtaining the occurrence times of the heating instruction at the current time and within the set time, if the occurrence times is greater than or equal to the set times, determining that the target state is the first state (that is, the target heating capacity is greater than the set heating capacity or the current heating capacity of the air conditioner), if the current time period is in the preset rest time period (for example, the night sleep time period or the noon sleep time period), determining that the target state is the second state (that is, the target operation noise is less than the set noise threshold), and if the occurrence times is less than the set times and the current time is in the time period other than the preset rest time period, determining that the target state is the state other than the first state and the second state. When the target state is other than the first state and the second state, the requirement of no large heating capacity or low noise is indicated, the air conditioner can achieve the effect of large heating capacity or low noise without utilizing the matching operation of the radiation module and the heat pump module, the operation power of the radiation module is reduced at the moment, even the radiation module is closed, the heating operation of the air conditioner can be ensured to meet the actual comfortable requirement of a user, and meanwhile, the energy consumption of the air conditioner is reduced.
Further, after the step of obtaining the target state of the heating operation of the air conditioner, the method further includes: when the target state is the first state, controlling a heat pump module of the air conditioner to maintain heating operation and controlling the radiation module to maintain an opening state; and when the target state is the second state, controlling the heat pump module to stop heating operation and controlling the radiation module to maintain an opening state. Under the first state, heat pump module through the air conditioner heats with the radiation module is synchronous, is favorable to two module cooperations to make the great heat of air conditioner exportable, realizes heating fast to the indoor environment, guarantees that the indoor environment can reach user's comfortable temperature fast. In the second state, the heat pump module through the air conditioner is closed (the compressor and/or the indoor fan are closed), and the radiation module maintains the opening state and releases radiation waves to heat the indoor air, so that the heat required by the indoor environment is maintained through the radiation module while the running noises of the compressor, the fan and the like of the heat pump module are reduced, and the thermal comfort of indoor environment users is ensured.
In this embodiment, in the operation process of the air conditioner, one of the three temperatures may be configured in advance as a default characteristic temperature, or one of the three temperatures may be selected as a characteristic temperature based on the actual operation condition of the air conditioner in combination with a preset rule, or all of the three temperatures may be used as a characteristic temperature.
Specifically, when the characteristic temperature is one of the three temperatures, one of the steps S21, S22 and S23 may be selected to determine the control parameter of the radiation temperature of the radiation module. When the characteristic parameter is more than one of the three temperatures, the step S20 may include at least two of the steps S21, S22 and S23, and when any temperature reaches a corresponding condition, the operation of the radiation module and/or the heat dissipation module corresponding to the radiation module is controlled according to the corresponding control parameter.
In other embodiments, the characteristic temperature may be a temperature other than the three temperatures, for example, an outdoor ambient temperature, an outlet air temperature, or the like.

The indoor heat exchanger is generally low in temperature and the radiation module is high in heat demand at the starting stage of heating, the radiation temperature of the radiation module is controlled based on the temperature of the radiation module, and the heat radiated by the radiation module can be ensured to meet the requirement of improving the heating efficiency of the air conditioner and simultaneously the service life of the radiation module is prolonged; the heating lasts for a certain period of time, the temperature of the indoor heat exchanger is high enough, and the radiation temperature of the radiation module is regulated and controlled based on the temperature of the indoor heat exchanger, so that the heating efficiency of the air conditioner can be ensured, the energy consumption of the radiation module can be reduced, and the heating energy efficiency of the heat pump module can be improved; when the heating operation time is long enough, the radiation temperature of the radiation module is regulated and controlled based on the indoor environment temperature, so that the heating efficiency of the air conditioner is ensured, and the energy consumption of the radiation module is reduced.
In other embodiments, the characteristic temperature may be calculated by combining the three temperatures and a preset formula, and the control parameter of the radiation temperature of the radiation module may be determined based on the calculated characteristic temperature.
