The invention provides a control method of a solar air conditioner.
The solar air conditioner comprises a solar power supply assembly, a refrigerant circulation assembly and an energy storage assembly, wherein the solar power supply assembly is used for converting solar energy into electric energy for the operation of the solar air conditioner; the refrigerant circulating assembly realizes refrigeration or heating through phase change of refrigerants therein so as to adjust environmental parameters such as indoor temperature, indoor humidity and the like; the energy storage component comprises an energy storage material, the phase change of the energy storage material can store energy, and the stored energy, such as cold or heat, can be released when necessary, so that the refrigeration or heating of the refrigerant circulation component is supplemented.
In a first embodiment of the present invention, as shown in fig. 1, a solar air conditioner control method includes the steps of:
s100, acquiring power supply power of a solar power supply assembly and power consumption power of a refrigerant circulating assembly;
the power supply power of the solar power supply assembly reflects the power supply capacity of the solar power supply assembly, and is related to the intensity of the effective light received by the solar power supply assembly, the stronger the intensity of the effective light is, the larger the power supply power of the solar power supply assembly is, and specifically, the power supply power can be obtained by calculating the product of the output voltage and the output current of the solar power supply assembly. The electric power consumption of the refrigerant circulation component comprises the sum of power consumed by components such as a compressor, an outdoor fan arranged on the side of the outdoor heat exchanger, an indoor fan arranged on the side of the indoor heat exchanger and the like, namely the power consumed in the real-time refrigerating or heating process of the solar air conditioner, and can be obtained by calculating the product of the voltage and the current of the refrigerant circulation component, or by inquiring a preset power meter according to environmental parameters and user setting parameters.
S200, comparing power supply power with power utilization power;
as the intensity of the effective light increases, the power supply increases. According to the environment parameters and the set parameters of the user, wherein the environment parameters comprise indoor temperature, outdoor temperature, indoor area and the like, and the set parameters comprise set temperature, set wind speed and the like, the power consumption of the refrigerant circulation assembly can be obtained. And providing reference for the power supply state of the solar air conditioner by comparing the power supply power with the power consumption power so as to wait for adjustment in the subsequent steps.
And S310, when the power supply power is smaller than the electricity utilization power, reducing the electricity utilization power of the refrigerant circulation assembly, and controlling the energy storage assembly to operate in an energy release mode so that the energy storage assembly compensates the refrigerating capacity or the heating capacity of the refrigerant circulation assembly.
The energy storage component comprises an energy storage material, and accumulation or release of cold accumulation or heat accumulation can be realized through the phase change process of the energy storage material, so that the refrigerant circulation component is supplemented. In order to fully utilize solar energy and improve the energy-saving effect of the solar air conditioner, the energy storage of the energy storage component is usually carried out under the power supply of the solar power supply component, and the commercial power supply is not used or is rarely used. Specifically, when the power supply power is smaller than the power consumption power, it is indicated that the power supply capacity of the solar power supply assembly is insufficient, and the refrigerant circulation assembly cannot normally operate to meet the set parameters of the user only by means of the solar power supply assembly. The power consumption of the refrigerant circulation assembly is reduced, so that the power supply pressure of the solar power supply assembly is reduced. In a specific example, the refrigerant circulation assembly only uses the solar power supply assembly as a power supply, and correspondingly, the reduced power consumption of the refrigerant circulation assembly should be less than or equal to the power supply of the solar power supply assembly. Meanwhile, in order to make up for the deficiency of the refrigerating capacity or the heating capacity of the refrigerant circulation component, the energy storage component is controlled to operate in an energy release mode, and the cold storage capacity or the heat storage capacity accumulated in the energy storage component in advance is released, so that the total refrigerating capacity or the total heat capacity of the solar air conditioner can meet the requirements of users. The energy storage assembly compensates for the deficiency of refrigerating capacity or heating capacity of the refrigerant circulation assembly, and a storage battery or commercial power does not need to be adopted to supplement power for the refrigerant circulation assembly, so that the energy-saving effect of the solar air conditioner is improved. Of course, in another specific example, if the cold storage amount or the heat storage amount released by the energy storage component is not enough to compensate for the refrigerating capacity or the heating capacity which is in shortage when the power consumption of the refrigerant circulation component is reduced to be less than or equal to the power supply power, the power consumption of the refrigerant circulation component may also be appropriately reduced to reduce the power supply pressure of the solar power supply component, and meanwhile, the commercial power is used to supplement the power supply for the refrigerant circulation component, and the energy storage component is controlled to operate in the energy release mode to compensate for the refrigerating capacity or the heating capacity of the refrigerant circulation component. In the specific example, compared with the method that the storage battery or the commercial power is directly used for supplementing the electricity of the refrigerant circulating assembly, the solar air conditioner has the advantages that the power consumption is low, the user requirements are met, meanwhile, the solar energy is fully utilized, and the energy-saving effect of the solar air conditioner is improved.
In this embodiment, the solar air conditioner includes a solar power supply module, a refrigerant circulation module and an energy storage module; the control method of the solar air conditioner comprises the following steps: acquiring power supply power of a solar power supply assembly and power consumption power of a refrigerant circulating assembly; comparing the power supply power with the power consumption power; when the power supply power is smaller than the electricity utilization power, the electricity utilization power of the refrigerant circulation assembly is reduced, and the energy storage assembly is controlled to operate in an energy release mode, so that the energy storage assembly compensates the refrigerating capacity or the heating capacity of the refrigerant circulation assembly. The cold storage amount or the heat storage amount is accumulated in advance through the energy storage assembly, when the power supply of the solar power supply assembly is not enough to maintain the operation of the refrigerant circulation assembly, the refrigerating amount or the heating amount of the refrigerant circulation assembly is compensated through the energy storage released by the energy storage assembly, the user demand is met, meanwhile, the electric energy consumption of the solar air conditioner is reduced, the solar air conditioner can operate in an energy-saving mode, the energy storage assembly is low in cost, free of pollution, capable of storing energy repeatedly and long in service life, and particularly under the condition that the energy storage amount in the energy storage assembly is converted from previous redundant solar energy, the energy-saving effect of the solar air conditioner is greatly improved.
In the second embodiment of the present invention, as shown in fig. 2, after step S200, the solar air conditioner control method further includes the steps of:
and step S320, when the power supply power is greater than or equal to the power consumption power, controlling the refrigerant circulation assembly to operate under the power supply of the solar power supply assembly.
When the power supply power is greater than or equal to the power consumption power, the power supply of the solar power supply assembly is enough to support the operation of the refrigerant circulation assembly, and in order to reduce the electric energy consumption of the solar air conditioner, the refrigerant circulation assembly is controlled to operate under the power supply of the solar power supply assembly, namely, solar energy is preferentially adopted to supply power for the refrigerant circulation assembly, so that the energy-saving effect of the solar air conditioner is improved.
In the third embodiment of the present invention, as shown in fig. 3, after step S200, the solar air conditioner control method further includes the steps of:
step S331, when the power supply power is larger than or equal to the power consumption power, acquiring the residual energy storage of the energy storage component;
step S332, comparing the residual stored energy with a first preset stored energy;
and S333, when the residual energy storage amount is smaller than the first preset energy storage amount, controlling the energy storage assembly to operate in an energy storage mode.
When the power supply power is greater than or equal to the power consumption power, the solar power supply assembly is enough to support the operation of the refrigerant circulation assembly so as to meet the requirements of users. In this case, the energy storage assembly does not need to operate in the energy release mode to compensate for the cooling capacity or the heating capacity of the refrigerant circulation assembly. However, in order to avoid insufficient energy stored by the energy storage component when the energy storage component is required to release energy, when the power supply power is greater than the power consumption power, the remaining stored energy of the energy storage component is obtained and compared with the first preset stored energy amount to judge whether the energy storage component needs to be controlled to operate in an energy storage mode so as to store energy in advance, and thus, preparation is made for the compensation refrigerant circulation component. And when the residual energy storage amount is smaller than the first preset energy storage amount, indicating that the energy storage amount in the energy storage assembly is lower at the moment, and controlling the energy storage assembly to operate in an energy storage mode. Specifically, the energy storage assembly can operate under the power supply of a mains supply and also can operate under the power supply of the solar power supply assembly, and certainly, in order to improve the energy-saving effect of the solar air conditioner, the solar power supply assembly is preferentially adopted to supply power for the energy storage of the energy storage assembly, and when the power supply quantity of the solar power supply assembly is insufficient, the power is supplied by the mains supply and other modes.
In a fourth embodiment of the present invention, as shown in fig. 4, the solar air conditioner control method further includes the steps of:
s400, acquiring the energy storage power of an energy storage component;
s500, comparing the sum of the power supply power and the power consumption power plus the energy storage power;
and S600, when the power supply power is greater than or equal to the sum of the power consumption power and the energy storage power, controlling the refrigerant circulation assembly to operate under the power supply of the solar power supply assembly, and controlling the energy storage assembly to operate in an energy storage mode under the power supply of the solar power supply assembly.
The stored energy power is the power consumed by the energy storage component when operating in the energy storage mode, i.e. during the storage of cold or heat. When the power supply power is greater than or equal to the sum of the power consumption power and the energy storage power, the energy storage assembly is controlled to operate in an energy storage mode under the power supply of the solar power supply assembly, so that energy is stored for subsequent compensation of the refrigerant circulation assembly, sufficient solar energy in the current state is fully utilized, the commercial power energy consumption of the solar air conditioner is reduced, and the energy-saving effect of the solar air conditioner is improved
In a fifth embodiment of the present invention, the solar air conditioner further comprises a commercial power supply assembly;
as shown in fig. 5, when the power supply power is less than the power consumption power, after the step of controlling the energy storage assembly to operate in the energy release mode, the solar air conditioner control method further includes the steps of:
step S341, obtaining the residual energy storage of the energy storage component;
step S342, comparing the residual stored energy with a second preset stored energy;
and S343, when the residual energy storage amount is smaller than the second preset energy storage amount, controlling the commercial power supply assembly to supply power to the refrigerant circulation assembly.
It should be noted that the preconditions of step S341, step S342 and step S343 are all when the power supply is less than the power consumption. And when the residual energy storage amount is smaller than the second preset energy storage amount, the fact that the residual energy storage amount in the energy storage assembly is insufficient to compensate the refrigerating capacity or the heating capacity of the refrigerant circulation assembly is shown. In this case, if only the energy storage module is still used as the compensation of the refrigerant circulation module, the operation of the solar air conditioner cannot meet the requirement of the user. In order to avoid discomfort for a user, the commercial power supply assembly is controlled to supply power to the refrigerant circulation assembly, specifically, the refrigerant circulation assembly can operate under the common power supply of the solar power supply assembly and the commercial power supply assembly, or only operate under the power supply of the commercial power supply assembly, so as to make up the deficiency of solar power supply, and make the operation of the solar air conditioner meet the requirements of the user. Of course, in order to improve the energy-saving effect of the solar air conditioner, solar power is preferentially adopted, and when the solar power is insufficient, commercial power is adopted for supplying power.
Further, in a sixth embodiment of the present invention, as shown in fig. 6, when the power supply power is smaller than the power consumption power, after step S341, the method further includes the following steps:
step S344, comparing the residual stored energy with a third preset stored energy;
and step S345, when the residual energy storage amount is greater than or equal to a third preset energy storage amount, controlling the refrigerant circulation assembly to operate under the power supply of the solar power supply assembly.
The precondition of step S341, step S344 and step S345 is that when the power supply is smaller than the power consumption, there is no definite sequence relationship between step S344 and step S342. The third preset energy storage amount corresponds to the residual energy storage amount of the energy storage assembly capable of compensating the refrigerating capacity or the heating capacity of the refrigerant circulation assembly, and obviously, the third preset energy storage amount is larger than or equal to the second preset energy storage amount. When the residual energy storage amount is larger than or equal to the third preset energy storage amount, the energy storage assembly is indicated to be capable of compensating the refrigerating capacity or the heating capacity of the refrigerant circulation assembly, at the moment, the refrigerant circulation assembly is controlled to operate under the power supply of the solar power supply assembly, and other modes such as commercial power supply and the like are not adopted, so that the solar energy is fully utilized, and the energy-saving effect of the solar air conditioner is improved.
Further, in the seventh embodiment of the present invention, as shown in fig. 7, when the power supply power is smaller than the power consumption power, after step S341, the method further includes the following steps:
step S346, comparing the residual stored energy with a fourth preset stored energy;
and step S347, when the residual energy storage amount is smaller than the fourth preset energy storage amount, controlling the energy storage assembly to operate in an energy storage mode under the power supply of the commercial power supply assembly until the residual energy storage amount is larger than or equal to the fifth preset energy storage amount.
The precondition of step S341, step S346 and step S347 is that when the power supply is smaller than the power consumption, there is no definite sequence relationship between step S346 and step S342. The fourth preset stored energy corresponds to the remaining stored energy in a state where the energy storage assembly has failed to effectively release the stored energy, the fourth preset stored energy is less than or equal to the second preset stored energy, and the fifth preset stored energy is greater than the fourth preset stored energy. When the residual energy storage amount is smaller than the fourth preset energy storage amount, the energy storage assembly compensates the refrigerant circulation assembly by means of the energy storage assembly which cannot effectively release the stored energy. In order to avoid sudden situations such as power failure and the like, the solar air conditioner cannot operate completely, under the circumstance, the commercial power supply assembly supplies power to the energy storage assembly and operates in an energy storage mode, and therefore the residual energy storage amount of the energy storage assembly is increased until the residual energy storage amount is larger than or equal to the fifth preset energy storage amount. The fifth preset energy storage amount corresponds to the residual energy storage amount required by the solar air conditioner for the preset time length in the lowest power operation, and the solar air conditioner is prevented from stopping operation due to the occurrence of emergency conditions such as power failure, so that the user experience is guaranteed as much as possible.
In an eighth embodiment of the present invention, the refrigerant circulation assembly includes a compressor and an indoor fan; the step of reducing the power consumption of the refrigerant circulation assembly comprises the following steps:
step S311, reducing the running frequency of the compressor; or the like, or, alternatively,
and S312, reducing the running rotating speed of the indoor fan.
In the operation process of the solar air conditioner, the power consumed by the compressor is the main part of the power consumed by the refrigerant circulation assembly, and the power consumption of the refrigerant circulation assembly can be effectively reduced by reducing the operation frequency of the compressor. Meanwhile, the frequency conversion technology of the compressor is mature, and the control method for reducing the power consumption is very simple and convenient. Of course, the power consumption of the refrigerant circulation assembly can be reduced by reducing the rotating speed of the indoor fan, and the control method for changing the rotating speed of the indoor fan is quite simple and convenient.
In the ninth embodiment of the present invention, as shown in fig. 8, step S310 includes:
step 313, obtaining the predicted intensity of the effective light received by the solar power supply assembly within a preset time period after the current moment;
step S314, comparing the predicted intensity with a preset intensity;
step S315, when the predicted intensity is smaller than the preset intensity, controlling the energy storage assembly to operate at a first energy release power;
and step S316, when the predicted intensity is greater than or equal to the preset intensity, controlling the energy storage assembly to operate at a second energy release power.
Wherein the first energy releasing power is smaller than the second energy releasing power. In this embodiment, the power of the energy releasing component for releasing the stored energy is determined according to the predicted intensity of the effective light within the preset time period after the current time. Specifically, in the operation process of the solar air conditioner, the power supply capacity of the solar power supply assembly is closely related to the intensity of the effective light received by the solar power supply assembly, and the stronger the intensity of the effective light is, the stronger the power supply capacity of the solar power supply assembly is. However, in a natural environment, the intensity of the effective light is not constant, but is related to the sunrise and sunset time and the propagation condition of the light in the atmosphere, and the specific energy release parameters of the energy storage component can be adjusted in time according to the predicted conditions of the effective light by predicting the predicted intensity of the light in a preset time period after the current time so as to adapt to the change of the intensity. When the predicted intensity is smaller than the preset intensity, the power supply capacity of the solar power supply assembly is weaker in a preset time period, and at the moment, the first energy release power which is smaller can be used for controlling the energy storage assembly to release the cold accumulation amount or the heat accumulation amount so as to avoid that the quick release causes that the power supply such as commercial power has to be relied on in the later period; when the predicted intensity is greater than or equal to the preset intensity, the power supply capacity of the solar power supply assembly is stronger in the preset time period, at the moment, the second energy release power which is larger can be used for controlling the energy storage assembly to release the cold storage amount or the heat storage amount so as to make up the deficiency of the refrigerant circulation assembly, reduce the electric energy such as commercial power consumed in the current state as much as possible, promote the full utilization of solar energy and improve the energy-saving effect of the solar air conditioner. The predicted intensity of the effective light may be obtained by analyzing historical data of the effective light intensity, for example, by calculating the intensity of the effective light in a past period of time under similar conditions to obtain the predicted intensity in a preset period of time, or by analyzing information such as weather forecast including sunrise time, sunset time, and weather conditions for determining the transmittance of the light in the atmosphere, such as sunny, rain, snow, fog, and the like. Specifically, the weather forecast can be obtained through a big data server in the same internet with the solar air conditioner, or can be obtained through a portable intelligent terminal such as a mobile phone and a tablet personal computer. The weather forecast on the server or the intelligent terminal can be updated in real time, so that the accuracy of predicting the effective light intensity is improved, and the operation of the energy storage assembly is more accurate.
