s301, when the air conditioner enters a defrosting mode, the control panel starts a defrosting electric heater arranged on the air conditioner condenser to heat the air conditioner condenser;
it should be noted that the air conditioner condenser frosts only when the air conditioner heats, and in general, when the outdoor temperature is about 2 degrees celsius or below, the air conditioner condenser frosts easily, and when the outdoor temperature is above 2 degrees celsius, the air conditioner condenser does not frosts.
It can be understood that before the air conditioner enters the defrosting mode, the air conditioner operates in the heating mode, at the moment, the outdoor unit absorbs heat, the indoor unit dissipates heat, when the outdoor temperature is lower, the outdoor unit still needs to absorb heat, at the moment, the temperature of the condenser body of the air conditioner is reduced to be below 0 ℃, surrounding moisture can be quickly condensed into frost, and whether the air conditioner enters the defrosting mode or not is determined according to the temperature monitored by the outdoor environment temperature sensor or the defrosting sensor.
After the air conditioner enters a defrosting mode, the operation frequency of the outer machine compressor is reduced, when the frequency of the outer machine compressor is reduced to a preset frequency, the control panel controls the air conditioner to start a defrosting electric heater arranged on an air conditioner condenser, the defrosting electric heater starts to preheat and heat the air conditioner condenser, after the compressor stops operating, an outer machine fan stops after operating for a period of time, the four-way valve reverses, the outer machine compressor restarts, the air conditioner starts a refrigerating mode, and the air conditioner condenser starts to defrost.
And S302, when the temperature of the air conditioner condenser reaches a temperature threshold value, the control board stops the operation of the defrosting electric heater and exits the defrosting mode.
It can be understood that, after the air conditioner enters the defrosting mode, the defrosting electric heater starts to heat the air conditioner condenser, and the temperature of the air conditioner condenser is increased, so that the defrosting speed of the air conditioner condenser is increased, and the defrosting time of the air conditioner condenser is shortened. When the temperature of the condenser of the air conditioner reaches the temperature threshold value, the air conditioner exits the defrosting mode, and the control panel controls the air conditioner to stop the operation of the defrosting electric heater.
After the air conditioner exits the defrosting mode, the outer machine compressor is shut down and stopped, the four-way valve is reversed, when the four-way valve is reversed, the control panel controls the air conditioner to stop the operation of the defrosting electric heater, then the outer machine compressor is restarted, the frequency is slowly increased, and the air conditioner is started in the heating mode.
The temperature of the air conditioner condenser can be obtained through an outdoor environment temperature sensor or a defrosting sensor. The temperature threshold can be set according to actual conditions, and generally speaking, when the surface temperature of the air conditioner condenser reaches above 0 ℃, frost on the air conditioner condenser begins to melt.
In this embodiment, when the air conditioner enters the defrosting mode, the control board starts a defrosting electric heater arranged on the air conditioner condenser to heat the air conditioner condenser, and when the temperature of the air conditioner condenser reaches a temperature threshold, the control board stops the operation of the defrosting electric heater, and the air conditioner exits the defrosting mode. In the method, the air conditioner condenser is heated by the defrosting electric heater, so that the temperature of the air conditioner condenser is quickly increased, the defrosting speed of the air conditioner condenser is increased, the defrosting time of the air conditioner is shortened, and the experience of a user on the air conditioner is improved.
On the basis of the above embodiment, further, the defrosting method further includes:
in the defrosting mode, monitoring the electric quantity of a storage battery connected with the defrosting electric heater in real time;
when the electric quantity of the storage battery is not lower than the first electric quantity threshold value, the storage battery supplies power to the defrosting electric heater;
when the electric quantity of the storage battery is lower than the first electric quantity threshold value, the control panel supplies power to the defrosting electric heater.
It should be noted that, this embodiment relates to three main parts, namely defrosting electric heater, control panel and battery, and two pairs of interconnect between the three, namely defrosting electric heater is connected with control panel and battery simultaneously, and the control panel is connected with the battery too.
It can be understood that the battery is connected with the control panel, and under the condition that the air conditioner got into the defrosting mode, the control panel can real time monitoring the electric quantity of battery, when the electric quantity of battery was not less than first electric quantity threshold value, provided the power for defrosting electric heater by the battery, when the electric quantity of battery was less than first electric quantity threshold value, the electric quantity of battery can't satisfy defrosting electric heater's normal operating condition this moment, then provided the power for defrosting electric heater by the control panel.
Wherein, the first electric quantity threshold value can be set according to the actual situation. For example, in one specific embodiment, the first charge threshold is set to 20%, that is, when the charge of the battery is not lower than 20%, the electric heater for defrosting is powered by the battery, and when the charge of the battery is lower than 20%, the electric heater for defrosting is powered by the control board.
In this embodiment, through under the defrosting mode at the air conditioner, the electric quantity of real time monitoring battery, when the electric quantity of battery is higher than first electric quantity threshold value, charge for defrosting electric heater through the battery, when the electric quantity of battery is less than first electric quantity threshold value, the electric quantity of battery is not enough to support the normal operating of defrosting electric heater promptly, directly give the battery power supply by the control panel, effectively guaranteed that defrosting electric heater can normal operating when the air conditioner defrosting, accelerated defrosting speed, reduced the defrosting time.
On the basis of the above embodiment, further, the defrosting method further includes:
when the electric quantity of the storage battery is lower than a second electric quantity threshold value, the storage battery is charged by the charging equipment or the control board, wherein the storage battery is charged by the control board only when the output current of the charging equipment is lower than a preset current value; wherein the second power threshold is higher than the first power threshold.
It is understood that the battery is charged by the charging device or control panel when the charge of the battery is above the first charge threshold and below the second charge threshold.
Specifically, under the condition that the electric quantity of the storage battery is in the electric quantity interval from the first electric quantity threshold value to the second electric quantity threshold value, if the output current of the charging equipment is lower than the preset current value, the power supply of the charging equipment to the storage battery at the moment cannot meet the requirement of the normal power supply of the storage battery to the defrosting electric heater, and the storage battery can be directly charged by the control board.
It should be noted that the battery is charged by the control board if and only if the output current of the charging device is lower than the preset current value, and otherwise, the battery is charged by the charging device.
The second electric quantity threshold value is higher than the first electric quantity threshold value, and the second electric quantity threshold value and the preset current value can be set according to actual conditions. For example, in a specific embodiment, when the charge of the storage battery is 20% higher than the first charge threshold and 75% lower than the second charge threshold, and the output current of the charging device is 1A and lower than the preset current value 2A, the control board charges the storage battery.
