Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

In the existing technology, most air conditioners determine whether to enter the defrost mode based on the outdoor unit ring temperature and the defrost sensor. When the defrost conditions are met, the air conditioner enters the defrost mode, the outdoor unit compressor reduces the frequency and stops, and the outdoor fan runs for a period of time. It stops after the time. After the four-way valve is reversed, the outdoor unit compressor starts, the air conditioner enters the air conditioning mode, and the outdoor unit starts to defrost. When the outdoor unit ambient temperature sensor reaches a certain temperature and lasts for a certain period of time, the defrost ends and the outdoor unit The compressor reduces frequency and stops. After the four-way valve is reversed, the outdoor compressor restarts and the air conditioner turns on the heating mode.

When the outdoor temperature is low, the frost on the outdoor unit of the air conditioner will be very thick, and defrosting will take a long time, thus affecting the user experience. Considering this, this application provides a defrosting system for an air conditioner, which can effectively speed up the defrosting and reduce the defrosting time when the air conditioner is defrosted, thus improving the user experience.

Figure 1 shows a system schematic diagram of the defrosting system of the air conditioner provided by this application. As shown in Figure 1, the defrost system includes: a defrost electric heater, which is arranged on the air conditioner condenser and heats the air conditioner condenser in defrost mode; a control panel, which is connected to the defrost electric heater and controls the defrost electric heater. Start and stop of the frost electric heater: when the air conditioner enters the defrost mode, start the defrost electric heater; and when the temperature of the air conditioner condenser reaches the temperature threshold, stop the operation of the defrost electric heater and exit the defrost mode .

It should be noted that electric heating is a process of converting electric energy into thermal energy. Correspondingly, the working principle of an electric heater is to use the thermal effect of electric current to make the electric current passing through the resistor work and generate heat, thereby converting electric energy into thermal energy. Electric heaters include pipeline electric heaters, thermal oil electric heaters, box heaters and electric heating elements, which can quickly bring objects to high temperatures and reduce the amount of electrical energy that is dispersed into the air and lost in resistance.

In terms of heating methods, electric heaters can perform overall heating and local heating of objects, and the type of object to be heated can be solid, liquid or gas.

In this embodiment, the defrost electric heater is connected to the control panel and is arranged on the air conditioning condenser. When the air conditioner is defrosting, it is used to heat the air conditioner condenser with its own heat, speeding up the temperature rise of the air conditioner condenser, thereby speeding up the defrosting time of the air conditioner condenser.

Among them, the specific arrangement of the defrosting electric heaters on the air conditioning condenser and the number of defrosting electric heaters can be set according to the actual situation. Specifically, the defrosting electric heaters can be evenly arranged on the air-conditioning condenser, or can be randomly arranged on the air-conditioning condenser; the number of defrosting electric heaters can be one or multiple, and is not specifically limited.

It should be noted that the defrost electric heater is arranged on the air-conditioning condenser, and its size should be compatible with the air-conditioning condenser.

In a specific embodiment, three defrosting electric heaters are arranged on the air conditioning condenser, and the spacing between the three defrosting electric heaters can be adjusted according to actual conditions. Specifically, Figure 2 shows a schematic layout diagram of the defrosting electric heater provided by this application. As shown in Figure 2, three electric heaters are arranged on the air conditioner condenser. When the air conditioner is defrosted, the defrosting electric heater The heater can heat the air conditioner condenser, causing the air conditioner condenser to heat up faster, thereby speeding up the defrost time of the air conditioner condenser.

The control panel is the core component of the computer controller, usually composed of hardware and software, and is used for automatic control of large equipment and systems such as air conditioners, elevators, and building automation.

In this embodiment, the control panel is connected to the defrost electric heater. Based on this connection relationship, the control panel can control the start and stop of the defrost electric heater. At the same time, based on this connection relationship, when the defrost electric heater When the power of the heater is low, the control panel can also directly charge the defrost electric heater.

It can be understood that the defrost system of the air conditioner includes a defrost electric heater and a control panel. When the air conditioner enters the defrost mode, the control panel controls the air conditioner to start the defrost electric heater, and the defrost electric heater starts to preheat to heat. The arrangement carrier of the defrost electric heater is the air-conditioning condenser. After the air-conditioning condenser is heated, its surface temperature will rise rapidly, so the defrosting speed of the air-conditioning condenser will be accelerated accordingly, greatly shortening the time required for defrosting the air-conditioning condenser. time.

When the temperature of the air conditioner condenser reaches the temperature threshold, the defrost mode is exited, and the control panel controls the air conditioner to stop running the defrost electric heater. Among them, the temperature threshold can be set according to the actual situation. Generally speaking, when the surface temperature of the air-conditioning condenser reaches above 0 degrees Celsius, the frost on the air-conditioning condenser begins to melt.

In this embodiment, the defrosting system of the air conditioner includes a defrosting electric heater and a control panel. The defrosting electric heater is arranged on the air conditioner condenser. When the air conditioner enters the defrosting mode, it is connected to the defrosting electric heater. The connected control board controls the air conditioner to start the defrost electric heater, and the defrost electric heater heats the air conditioner condenser. When the temperature of the air conditioner condenser reaches the temperature threshold, the control board controls the air conditioner to stop running the defrost electric heater and exit. Defrost mode. During the operation of the defrosting system of the air conditioner, the air conditioner condenser is heated by the defrost electric heater, causing the temperature of the air conditioner condenser to rise rapidly, speeding up the defrosting speed of the air conditioner condenser, and reducing the defrosting time of the air conditioner. Improves users’ experience with air conditioners.

Based on the above embodiment, further, the defrosting system further includes: a battery, which is connected to the control panel and the defrosting electric heater, and provides power for the defrosting electric heater.

The defrosting system of the air conditioner provided in this embodiment includes a defrosting electric heater, a control panel and a battery. The defrosting electric heater and control panel have been described in detail in the previous embodiment and will not be repeated here. Repeat. Among them, the battery can regenerate the internal active materials by charging and store electrical energy into chemical energy; when it needs to be discharged, the chemical energy can be converted into electrical energy again.

It can be understood that the battery is connected to the control panel and the defrost electric heater at the same time. Specifically, the battery is connected to the defrost electric heater in order to provide power for the defrost electric heater in the defrost mode to ensure that The defrost electric heater operates normally. The connection between the battery and the control board enables the control board to monitor the battery's power in real time. When the battery's power is insufficient, the control board can charge the battery in time.

In this embodiment, the defrosting system of the air conditioner includes a defrosting electric heater, a control panel, and a battery. The battery is connected to the control panel and the defrosting electric heater at the same time for providing electric heating for defrosting in the defrosting mode. The heater provides power to ensure that the defrosting electric heater can operate normally when the air conditioner is defrosting, so as to speed up the defrosting speed and reduce the defrosting time.

Based on the above embodiment, further, the defrosting system further includes: a photovoltaic power generation panel, which is connected to the control panel and the battery, and charges the battery.

The defrosting system of the air conditioner provided in this embodiment includes a defrosting electric heater, a control panel, a battery, and a photovoltaic power generation panel. The defrosting electric heater, control panel, and battery have been described in the previous embodiment. No further details will be given here.

The photovoltaic power generation panel in this embodiment uses solar cells to directly convert sunlight energy into electricity. It is directly converted into electrical energy, and the converted electrical energy is used to charge the battery.

It can be understood that during the defrosting process of the air conditioner, the battery is used to provide power for the defrosting electric heater. Considering the power demand of the battery, a photovoltaic power generation panel is added to charge the battery. The photovoltaic power generation panel is connected to the control panel and the battery at the same time. The control board is connected to the battery and can monitor the battery power in real time. Based on the monitored battery power value, the control board controls the photovoltaic power generation panel to charge the battery. When there is not enough sunlight and the electric energy converted by the photovoltaic power generation panel is not enough to charge the battery, the control panel itself can also charge the battery.

In this embodiment, the defrost system of the air conditioner includes a defrost electric heater, a control panel, a battery, and a photovoltaic power generation panel. The photovoltaic power generation panel is used to charge the battery to ensure that the battery stores enough power, so that the battery can Provide power to the defrost electric heater when the air conditioner is defrosting.

FIG. 3 shows a schematic flow chart of the defrosting method of the air conditioner provided by this application. As shown in Figure 3, the defrosting method includes the following steps.

S301, when the air conditioner enters the defrost mode, the control panel starts the defrost electric heater arranged on the air conditioner condenser to heat the air conditioner condenser.

It should be noted that frost will only appear on the air conditioner condenser when the air conditioner is heating. Normally, when the outdoor temperature is around 2 degrees Celsius or below, the air conditioner condenser is prone to frost. When the outdoor temperature is above 2 When the temperature is above Celsius, frost will not form on the air conditioner condenser.

It can be understood that before the air conditioner enters the defrost mode, the air conditioner operates in the heating mode. At this time, the outdoor unit absorbs heat and the indoor unit dissipates heat. When the outdoor temperature is low, the outdoor unit still needs to absorb heat. At this time, the air conditioner condenser The body temperature will drop below 0 degrees Celsius, and the surrounding moisture will quickly condense into frost. Based on the temperature monitored by the outdoor ambient temperature sensor or defrost sensor, it is determined whether the air conditioner has entered defrost mode.

After the air conditioner enters the defrost mode, the outdoor compressor reduces the operating frequency. When the frequency of the outdoor compressor drops to the preset frequency, the control panel controls the air conditioner to start the defrost electric heater arranged on the air conditioner condenser. The defrost electric heater Start preheating and heat the air conditioner condenser. After the compressor stops running, the outdoor unit fan also stops after running for a period of time. The four-way valve reverses direction, the outdoor unit compressor restarts, the air conditioner turns on the cooling mode, and the air conditioner condenser starts defrosting. .

S302, when the temperature of the air conditioner condenser reaches the temperature threshold, the control board stops the defrost power heater operation and exit defrost mode.

It is understandable that after the air conditioner enters the defrost mode, the defrost electric heater starts to heat the air conditioner condenser, and the temperature of the air conditioner condenser will increase at an accelerated rate, thereby speeding up the defrosting speed of the air conditioner condenser and reducing the defrosting time of the air conditioner condenser. . When the temperature of the air conditioner condenser reaches the temperature threshold, the air conditioner exits the defrost mode, and the control panel controls the air conditioner to stop the operation of the defrost electric heater.

After the air conditioner exits the defrost mode, the outdoor compressor reduces the frequency and stops, and the four-way valve reverses direction. When the four-way valve reverses direction, the control panel controls the air conditioner to stop the operation of the defrost electric heater, and then the outdoor compressor restarts. , slowly increase the frequency, and the air conditioner turns on the heating mode.

Among them, the temperature of the air conditioner condenser can be obtained through the outdoor ambient temperature sensor or defrost sensor. The temperature threshold can be set according to the actual situation. Generally speaking, when the surface temperature of the air conditioning condenser reaches above 0 degrees Celsius, the frost on the air conditioning condenser begins to melt.

In this embodiment, when the air conditioner enters the defrost mode, the control panel starts the defrost electric heater arranged on the air conditioner condenser to heat the air conditioner condenser. When the temperature of the air conditioner condenser reaches the temperature threshold, the control panel stops defrosting. Frost electric heater operates and the air conditioner exits defrost mode. In this method, the air-conditioning condenser is heated by a defrosting electric heater, causing the temperature of the air-conditioning condenser to rise rapidly, speeding up the defrosting speed of the air-conditioning condenser, and reducing the defrosting time of the air-conditioning, thereby improving the user's awareness of the air-conditioning. sense of experience.

Based on the above embodiment, further, the defrosting method further includes:

In defrost mode, monitor the power of the battery connected to the defrost electric heater in real time;

When the battery power is not lower than the first power threshold, the battery supplies power to the defrost electric heater;

When the battery power is lower than the first power threshold, the control panel supplies power to the defrost electric heater.

It should be noted that this embodiment involves three main bodies, namely the defrost electric heater, the control panel and the battery, which are connected in pairs, that is, the defrost electric heater is connected to the control panel and the battery at the same time, and the control panel The board is also connected to the battery.

It can be understood that the battery is connected to the control board. When the air conditioner enters defrost mode, the control board will monitor the battery power in real time. When the battery power is not lower than the first power threshold, the battery will provide defrosting electric heating. When the battery power is lower than the first power threshold, the battery power cannot meet the normal operating conditions of the defrost electric heater. parts, the control panel provides power for the defrost electric heater.

The first power threshold can be set according to actual conditions. For example, in a specific embodiment, the first power threshold is set to 20%, that is, when the battery power is not less than 20%, the battery provides power to the defrosting electric heater, and when the battery power is less than 20% , the control panel provides power to the defrost electric heater.

In this embodiment, the power of the battery is monitored in real time in the defrost mode of the air conditioner. When the power of the battery is higher than the first power threshold, the defrosting electric heater is charged through the battery. When the power of the battery is lower than the first power threshold, the electric heater is charged. A power threshold, that is, when the power of the battery is not enough to support the normal operation of the defrosting electric heater, the control panel directly supplies power to the battery, effectively ensuring that the defrosting electric heater can operate normally when the air conditioner is defrosted and speeding up defrosting. speed, reducing defrost time.

Based on the above embodiment, further, the defrosting method further includes:

When the power of the battery is lower than the second power threshold, the charging device or the control board charges the battery, wherein the control board charges the battery only when the output current of the charging device is lower than the preset current value; wherein, the first The second power threshold is higher than the first power threshold.

It can be understood that when the power of the battery is higher than the first power threshold and lower than the second power threshold, the charging device or the control board charges the battery.

Specifically, when the power of the battery is in the power range from the first power threshold to the second power threshold, if the output current of the charging device is lower than the preset current value, the charging device cannot supply power to the battery at this time and cannot meet the requirements of the battery. To provide normal power supply to the defrost electric heater, the control panel can charge the battery directly.

It should be noted that if and only when the output current of the charging device is lower than the preset current value, the control board will charge the battery. In other cases, the charging device will charge the battery.

The second power threshold is higher than the first power threshold, and both the second power threshold and the preset current value can be set according to actual conditions. For example, in a specific embodiment, when the battery power is 20% higher than the first power threshold and 75% lower than the second power threshold, and the output current of the charging device is 1A, which is lower than the preset current value 2A, then The battery is charged from the control panel.

Charging equipment is any device that can provide power, or that can convert other energy sources into electrical energy and power the battery. For example, in a specific embodiment, the charging device is a photovoltaic power generation panel.

Figure 4 shows a schematic diagram of the power supply of the air conditioner provided by this application in defrost mode. As shown in Figure 4, it involves four main bodies, namely the defrost electric heater, control panel, battery and photovoltaic power generation panel. Among them, the control board and battery are connected to the other three main bodies respectively.

When the air conditioner enters defrost mode, the defrost electric heater starts and starts to heat the air conditioner condenser. During this process, the control panel will monitor the battery power at any time. When the battery power is higher than the first power threshold, which is 20% When the battery power is lower than the first power threshold, the control panel directly supplies power to the defrost electric heater.

When the battery's power is higher than the first power threshold but lower than the second power threshold, that is, 75%, the battery can be charged by the control panel or the photovoltaic power generation panel. Specifically, under normal circumstances (the output current of the photovoltaic power generation panel is not less than 2A, and there is sufficient sunlight at this time), the control panel controls the photovoltaic power generation panel to charge the battery. However, when the output current of the photovoltaic power generation panel is less than 2A, it means that At this time, there is not enough sunlight, and the electric energy converted by the photovoltaic power generation panel cannot provide sufficient power for the battery. Therefore, the control panel directly charges the battery.

That is to say, in Figure 4, the first choice to provide power for the defrost electric heater is the battery, and the first choice to charge the battery is the photovoltaic power generation panel. When the battery does not meet the conditions for powering the defrost electric heater , the control panel directly supplies power to the defrost electric heater. Similarly, when the photovoltaic power generation panel does not meet the conditions for charging the battery, the control panel directly charges the battery.

In this embodiment, a second power threshold is set for the battery's power, that is, when the battery's power is higher than the first power threshold and lower than the second power threshold, the battery can be charged through the charging device or the control panel, where, When the output current of the charging equipment is lower than the preset current value, the control board charges the battery directly. In other cases, the charging equipment charges the battery, ensuring that the battery stores sufficient power, so that the battery can provide power when the air conditioner is defrosted. Defrost electric heater provides power.

In this device, the air-conditioning condenser is heated by the defrosting electric heater, causing the temperature of the air-conditioning condenser to rise rapidly, speeding up the defrosting speed of the air-conditioning condenser, and reducing the defrosting time of the air conditioner, thus improving the user's awareness of the air conditioner. sense of experience.
