Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The following describes in detail the operation principle of the air conditioner according to the embodiment of the present application:

as shown in fig. 1, the compressor compresses a refrigerant (refrigerant), and sends the compressed refrigerant to the condenser through a pipe, and the high-temperature and high-pressure gaseous refrigerant releases heat in the condenser to change the gaseous refrigerant into a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is reduced in pressure by a capillary tube (throttle unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low temperature and low pressure liquid refrigerant is delivered to the evaporator where it evaporates from a liquid to a gas and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner is used for refrigerating, the heat exchanger of the outdoor unit is a condenser, and the heat exchanger of the indoor unit is an evaporator; on the contrary, when the air conditioner heats, the heat exchanger of the outdoor unit is an evaporator, and the heat exchanger of the indoor unit is a condenser.

From the above, it is known that the compressor is a key component for implementing various functions of the air conditioner, and thus, the compressor needs to obtain stable power supply to ensure normal operation of the various functions. In the related art, the input voltage of the air conditioner is wide, typically 110 volts (V), 150V, 180V, 220V, etc., but there is a strict limitation on the input current, for example, the magnitude of the supply current required for the variable frequency compressor is typically 15 to 18 amperes (a), and the magnitude of the supply current required for the variable frequency compressor is typically 3 to 5A.

The power supply method of the air conditioner provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 2, a power supply device applied to a power supply method of an air conditioner according to an embodiment of the present application includes: the solar energy power supply circuit, the storage battery power supply circuit, the alternating current power supply circuit and the power supply controller circuit.

The power supply method of the air conditioner provided by the embodiment of the application is implemented by the power supply controller of the power supply device, wherein the power supply controller can be a component independent of the air conditioner in the power supply device or can be a part of a power supply management circuit in the air conditioner.

Based on the above fig. 2, as shown in fig. 3, the method for supplying power to an air conditioner according to the embodiment of the present application may include the following steps 301 and 302:

step 301, calculating power supply when at least one of the solar power supply circuit, the storage battery power supply circuit and the alternating current power supply circuit is used for power supply, so as to obtain power supply under various different power supply modes.

Illustratively, the plurality of different power supply modes include: the solar power supply circuit is used alone to supply power, the storage battery power supply circuit is used alone to supply power, the alternating current power supply circuit is used alone to supply power, the solar power supply circuit and the storage battery power supply circuit are used in combination to supply power, the storage battery power supply circuit and the alternating current power supply circuit are used in combination to supply power, the solar power supply circuit and the alternating current power supply circuit are used in combination to supply power, and the solar power supply circuit, the storage battery power supply circuit and the alternating current power supply circuit are used in combination to supply power.

In an exemplary case of meeting the electricity demand of the air conditioner, the electricity supply cost of the solar power supply circuit is lower than the electricity supply cost of the battery power supply circuit, and the electricity supply cost of the battery power supply circuit is lower than the electricity supply cost of the alternating current power supply circuit.

In one possible implementation, the power supply cost of the separate power supply is lower than the power supply cost of the combined power supply, that is, in the case that both the separate power supply mode and the combined power supply mode can meet the power demand of the air conditioner, the power supply cost of the separate power supply mode is lower than the power supply cost of the combined power supply mode.

Based on the above, the power supply cost of the above multiple different power supply modes is sequentially from low to high: the solar power supply circuit is used alone to supply power, the storage battery power supply circuit is used alone to supply power, the alternating current power supply circuit is used alone to supply power, the solar power supply circuit and the storage battery power supply circuit are used in combination to supply power, the storage battery power supply circuit and the alternating current power supply circuit are used in combination to supply power, the solar power supply circuit and the alternating current power supply circuit are used in combination to supply power, and the solar power supply circuit, the storage battery power supply circuit and the alternating current power supply circuit are used in combination to supply power.

In the above-described combined power supply system, the power supply of the combined power supply system is the sum of the power supply powers of the power supply circuits included in the combined power supply system.

Step 302, selecting an optimal target power supply mode from the multiple different power supply modes to supply power to the air conditioner based on the power supply under the different power supply modes, the power supply priority of the different power supply modes and the rated power of the air conditioner when the air conditioner operates in the current working mode.

The power supply cost is as follows from low to high: the solar power supply circuit, the storage battery power supply circuit and the alternating current power supply circuit; the power supply priority is as follows from high to low: the solar power supply circuit, the storage battery power supply circuit under the condition that the residual electric quantity of the storage battery is larger than or equal to a preset threshold value, the alternating current power supply circuit and the storage battery power supply circuit under the condition that the residual electric quantity of the storage battery is smaller than the preset threshold value.

It should be noted that, in the embodiment of the present application, in the case where the ac power supply circuit is available, any power supply mode needs to preferably ensure that the remaining power in the storage battery of the storage battery power supply circuit is greater than or equal to a preset threshold (for example, 70% of the power) so that the air conditioner can be powered by the storage battery power supply circuit when the ac power supply circuit is unavailable (i.e., the mains power is off) and the power supply output by the solar power supply circuit is insufficient.

It should be noted that, when the air conditioner is not in operation, the electric energy generated by the solar panel can be stored in the storage battery, so as to avoid wasting resources.

Optionally, in the embodiment of the present application, the above multiple power supply modes may be screened according to the power supply power that can be provided by each power supply mode.

Specifically, the step 302 may include the following steps 302a and 302b:

step 302a, screening candidate power supply modes with power supply power larger than the rated power from the plurality of different power supply modes.

And step 302b, selecting the target power supply mode to supply power to the air conditioner based on the power supply cost of each power supply mode in the candidate power supply modes.

The above-mentioned multiple power supply modes may be initially screened based on the power supply power provided by each power supply mode, so as to screen out candidate power supply modes meeting the power demand of the air conditioner. And then, further screening out a target power supply mode with the lowest power supply cost from the candidate power supply modes, and supplying power to the air conditioner through the target power supply mode.

Specifically, in the case where the remaining battery power is greater than or equal to the preset threshold, the above step 302b may further include any one of the following steps 302b1 to 302b 4:

Step 302b1, determining the first power supply mode as the target power supply mode when the remaining battery level is greater than or equal to the preset threshold and the power supply power of the first power supply mode is greater than the rated power.

Wherein, the first power supply mode is: and the solar power supply circuit is independently used for supplying power.

For example, since the power supply cost of the solar power supply circuit is the lowest, the solar power supply circuit may be preferentially used to supply power to the air conditioner in the case that the power supply power of the solar power supply circuit is greater than the rated power.

Step 302b2, determining the second power supply mode as the target power supply mode when the remaining battery level is greater than or equal to the preset threshold, the power supply of the first power supply mode is less than or equal to the rated power, and the power supply of the second power supply mode is greater than the rated power.

Wherein, the second power supply mode is: and a power supply mode of supplying power by combining the solar power supply circuit and the storage battery power supply circuit.

For example, since the electric energy stored in the storage battery is also provided by the solar cell panel, in a case where the power supplied by the solar power supply circuit cannot meet the power demand of the air conditioner, but the power supplied by the power supply mode of supplying power by combining the solar power supply circuit and the storage battery power supply circuit can meet the power demand of the air conditioner, the air conditioner may be powered by the power supply mode of supplying power by combining the solar power supply circuit and the storage battery power supply circuit.

Step 302b3, determining a third power supply mode as the target power supply mode if the power supply power of the second power supply mode is greater than the preset threshold, and determining a fourth power supply mode as the target power supply mode if the power supply power of the first power supply mode is less than or equal to the rated power and the power supply power of the second power supply mode is less than or equal to the rated power.

Wherein, the third power supply mode is: a power supply mode of supplying power by combining the solar power supply circuit, the storage battery power supply circuit and the alternating current power supply circuit; the fourth power supply mode is as follows: and a power supply mode of independently using the alternating current power supply circuit to supply power.

Step 302b4, determining the second power supply mode or the fifth power supply mode as the target power supply mode when the remaining battery level is greater than or equal to the preset threshold, the power supply of the first power supply mode is less than or equal to the rated power, and the fourth power supply mode is unavailable.

Wherein, the fifth power supply mode is: a power supply mode of independently using the storage battery power supply circuit to supply power; the preset threshold value is changed within a preset floating range based on the outdoor environment temperature, and the preset threshold value is inversely related to the outdoor environment temperature.

In a possible implementation manner, the power supply method of the air conditioner provided by the embodiment of the present application may further include the following steps 303 and 304:

step 303, acquiring the outdoor environment temperature of the current environment.

Step 304, adjusting the preset threshold value in a preset floating range according to the outdoor environment temperature.

Wherein the preset threshold is inversely related to the outdoor ambient temperature.

It should be noted that, the steps 303 and 304 may be performed in real time or according to a preset execution period, and the steps 303 and 304 may be performed before any step or after any step.

It will be appreciated that the endurance of the battery is related to the outdoor environment temperature, and when the outdoor environment temperature is low, the endurance of the battery is greatly reduced, so the above-mentioned preset device can float within a certain range (for example, 50% to 80%) according to the outdoor environment temperature, so that in the case that the ac power supply circuit (i.e., mains power supply) is not available, the air conditioner can be powered by the battery power supply circuit, and the power supply time is less affected by the outdoor environment temperature.

For example, when the remaining battery power is greater than or equal to the preset threshold, and the power supply of the power supply mode of combining the solar power supply circuit and the battery power supply circuit to supply power still cannot meet the power demand of the air conditioner, the power supply mode of combining the solar power supply circuit, the battery power supply circuit and the ac power supply circuit to supply power may be used to supply power to the air conditioner.

For example, in order to ensure the stability of power supply to the air conditioner, it is necessary to determine whether the power supply of the power supply mode of power supply by using the solar power supply circuit and the battery power supply circuit in combination is greater than a preset threshold, if so, the air conditioner is powered by using the third power supply mode, otherwise, the air conditioner is powered by using the fourth power supply mode.

Specifically, in the case where the remaining battery power is less than the preset threshold, the above step 302b may further include any one of the following steps 302b5 to 302b 7:

step 302b5, determining the first power supply mode as the target power supply mode when the remaining battery level is smaller than the preset threshold and the power supply power of the first power supply mode is larger than the rated power, and charging the battery through the first power supply mode and/or a fourth power supply mode.

Step 302b6, determining a sixth power supply mode as the target power supply mode when the remaining battery power is less than the preset threshold and the power supply power of the first power supply mode is less than or equal to the rated power, and charging the battery through the sixth power supply mode.

Wherein, the sixth power supply mode is: and a power supply mode of supplying power by combining the solar power supply circuit and the alternating current power supply circuit.

It should be noted that, in order to ensure that the air conditioner can be continuously powered after power failure, when the remaining capacity of the storage battery is smaller than a preset threshold value, the storage battery can be charged by the solar power supply circuit and/or the ac power supply circuit based on the above steps.

Step 302b7, determining the second power supply mode or the fifth power supply mode as the target power supply mode when the remaining battery level is less than the preset threshold, the power supply of the first power supply mode is less than or equal to the rated power, and the fourth power supply mode is unavailable.

For example, when the output power of the solar power supply circuit is greater than the minimum power supply, the solar power supply circuit and the battery power supply circuit may be used in combination to supply power to the air conditioner; when the output power of the solar power supply circuit is smaller than or equal to the minimum power supply, the output power of the solar power supply circuit is smaller and can be ignored, and at the moment, the storage battery power supply circuit can be independently used for supplying power to the air conditioner.

Optionally, in the embodiment of the present application, since the output power of the solar panel changes with the change of the illumination intensity, and the electric energy generated and stored by the storage battery also decreases with the lapse of time, real-time monitoring is required to be performed so as to make adjustments in time, and ensure the stability of power supply.

Illustratively, after the step 302b3, the power supply method for an air conditioner according to the embodiment of the present application may further include the following step 305:

step 305, monitoring the total power of the solar power supply circuit and the storage battery power supply circuit in real time, if the total power is smaller than a preset threshold, disconnecting the solar power supply circuit and the storage battery power supply circuit, and independently using the ac power supply circuit to supply power to the air conditioner, and charging the storage battery through the solar power supply circuit and/or the ac power supply circuit.

It can be understood that when the total power of the solar power supply circuit and the storage battery power supply circuit is smaller than the preset threshold, the power provided by the solar power supply circuit and the storage battery power supply circuit is lower, and at this time, the air conditioner can be powered by the alternating current power supply circuit. Meanwhile, the solar power supply circuit and/or the alternating current power supply circuit can charge the storage battery, the power supply power of the solar power supply circuit needs to be judged, and if the power supply power of the solar power supply circuit is smaller than a certain threshold value, the solar power supply circuit and/or the alternating current power supply circuit can be used for charging the storage battery.
