All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the embodiments of the present invention, it is to be noted that unless otherwise explicitly specified or limited. "upper", "lower", "inner", and the like are used merely to indicate relative positional relationships, and when the absolute position of a described object is changed, the relative positional relationships may also be changed accordingly. Specific meanings of the above terms in the embodiments of the present invention can be understood by those of ordinary skill in the art according to specific situations.
It is to be understood that, unless otherwise expressly specified or limited, the term "coupled" is used broadly, and may, for example, refer to directly coupled devices or indirectly coupled devices through intervening media. Specific meanings of the above terms in the embodiments of the invention will be understood to those of ordinary skill in the art in specific cases.
The heating air-conditioning fan of the present invention will be described with reference to fig. 1 to 2.
As shown in fig. 1, the heating air-conditioning fan includes a heating device including a heat dissipation pipe 100, a heat conduction pipe 200, a heater 300, an air pipe 400 and a liquid pipe 500, wherein the heat dissipation pipe 100, the liquid pipe 500, the heat conduction pipe 200 and the air pipe 400 are sequentially connected end to form a circulation pipeline, a refrigerant is disposed in the circulation pipeline, and the heater 300 is used for heating the refrigerant. A throttle valve is arranged on the air pipe and/or the liquid pipe; preferably, the air pipe and the liquid pipe are both provided with a throttle valve.
Specifically, the heat dissipation pipe 100 and the heat conduction pipe 200 are copper pipes made of the same material as the heat exchange coil of the air conditioner. The copper pipe has light weight, good heat conductivity and high low-temperature strength; meanwhile, the copper pipe is high temperature resistant and can be used in various environments, the pressure resistance of the copper pipe is several times or even dozens of times of that of a plastic pipe and an aluminum plastic pipe, and the copper pipe can bear the highest water pressure in the current building. In a hot water environment, the pressure bearing capacity of the plastic pipe is obviously reduced along with the prolonging of the service life, and the mechanical property of the copper pipe is kept unchanged in all hot temperature ranges, so the pressure resisting capacity of the copper pipe is not reduced, and the aging phenomenon is avoided.
Specifically, the cross-sectional shapes of the heat dissipation pipe 100 and the heat conduction pipe 200 may be square or circular, and preferably, a circular pipe is used, and the distance between the circumferential outer wall of the circular pipe and the medium in the pipe is the same, so that the heat exchange efficiency is high.
Specifically, a throttle valve 600 is disposed on the air tube 400 and/or the liquid tube 500. Referring to fig. 1, in this embodiment, a throttle 600 is disposed on an air pipe 400, when an air-conditioning fan heats to meet a heat demand of a user, the heater 300 and the throttle 600 are closed, the air pipe 400 is blocked, and a high-temperature gaseous refrigerant does not flow into the heat dissipation pipe 100 and remains in the heat conduction pipe 200, so as to prevent heat dissipation in the heat conduction pipe 200, and improve a heat storage effect of the heat conduction pipe 200.
Specifically, the throttle 600 disposed on the air pipe 400 is an electronic expansion valve, and can adjust the gas flow rate in the air pipe 400, and control the flow rate and flow rate of the high-temperature gaseous refrigerant in the heat pipe 200 flowing into the heat dissipation pipe 100 by adjusting the opening degree of the electronic expansion valve, so as to control the heating temperature of the heating air-conditioning fan.
Preferably, a throttle valve 600 is provided on both the air pipe 400 and the liquid pipe 500. The throttle 600 disposed on the liquid pipe 500 may also be an electronic expansion valve having a cut-off function, so as to effectively prevent the high-temperature gaseous refrigerant of the heat pipe 200 from flowing back into the heat dissipating pipe 100 from the return port. In one aspect, the electronic expansion valve can control the flow rate of the refrigerant condensed in the heat dissipation pipe 100 flowing into the heat pipe 200 by adjusting the opening degree, and control the pipe pressure in the heat dissipation pipe 100 to control the heating temperature of the air conditioner fan. On the other hand, when the heater 300 is turned off, the throttle 600 of the liquid pipe 500 may be closed at the same time, so that the refrigerant condensed in the heat pipe 100 is prevented from flowing into the heat transfer pipe 200, thereby improving the heat storage effect of the heat transfer pipe 200.
It should be noted that the throttle valve 600 described in this embodiment also has a cut-off function, and the throttle valve described in this embodiment also includes a cut-off valve having only a cut-off function; likewise, a valve body with a shut-off function is also within the scope of the invention as defined for a throttle valve.
In the heating device of the air conditioner fan in this embodiment, the air pipe 400 and the liquid pipe 500 are at least provided with one throttle 600, preferably, the air pipe 400 and the liquid pipe 500 are both provided with the throttle 600, so that when the air conditioner fan reaches a heating temperature, the heater 300 can be closed, and the air pipe 400 and the two throttle 600 on the liquid pipe 500 can be closed at the same time.
After the two throttle valves 600 on the gas pipe 400 and the liquid pipe 500 are closed at the same time, the gas pipe 400 and the liquid pipe 500 are both blocked, and the refrigerant in the heat conducting pipe 200 can be kept at a certain temperature in the heat preservation box 700 for a long time, so that the heat loss caused by the continuous flow of the high-temperature refrigerant into the heat radiating pipe is prevented.
Preferably, when the air conditioner fan operates, the throttle 600 of the air pipe 400 is opened first to allow the high-temperature gaseous refrigerant to enter the heat dissipation pipe from the air pipe 400, and the throttle 600 of the liquid pipe 500 is opened after the air conditioner fan operates for a period of time, so that the forward circulation of the refrigerant is realized.
Preferably, the air conditioner heating apparatus further includes an insulation box 700, and the heat pipe 200 and the heater 300 are located in the insulation box 700.
Specifically, the heat insulation box 700 is made of a heat insulation material, such as polyurethane foam, polystyrene board, EPS, XPS, phenolic foam, glass wool, rock wool, etc., the heat insulation box 700 is in a hollow box shape, and the heat conduction pipe 200 and the heater 300 are both installed in the heat insulation box 700. The heat insulation box 700 can prevent heat loss in the heat pipe 200, and improve the heat storage effect of the high-temperature refrigerant in the heat pipe 200.
Preferably, the air pipe 400 and the liquid pipe 500 penetrate from the heat insulation box 700 and are connected to the heat dissipation pipe 100, and sealing devices are disposed at the connection positions of the air pipe 400 and the liquid pipe 500 and the heat insulation box 700, so as to achieve heat insulation and sealing of the heat insulation box 700.
Preferably, a heat storage medium, such as water or saline water, having a relatively large specific heat capacity and being safe and pollution-free is disposed in the heat insulation box 700, so that the heat conduction pipe 200 in the heat insulation box 700 can be better insulated and stored.
Specifically, the air conditioner fan further includes a controller for controlling the heater 300 to heat the refrigerant and controlling the opening of the throttle valve 600.
In the heating air-conditioning fan of this embodiment, the heater 300 heats the refrigerant in the circulation pipeline, and particularly, the temperature of the refrigerant in the heat pipe 200 is heated. The refrigerant in the heat pipe 200 is gradually heated and gasified, and the gasified high-temperature refrigerant flows into the heat pipe 100 and exchanges heat with the air blown by the fan of the air conditioner through the heat pipe 100, so that the air conditioner blows hot air to heat the surrounding environment. The heat-dissipated refrigerant is gradually cooled and condensed, and the condensed liquid refrigerant returns to the heat conduction pipe 200 to be heated, thereby forming a heating cycle.
Meanwhile, after the throttle valves 600 on the liquid pipe 500 and the air pipe 400 are closed, the heat conduction pipe 200 is in a relatively closed state, so that the air-conditioning fan has a heat storage function. Moreover, even when the heating air-conditioning fan is not turned on (the user does not turn on the heating air-conditioning fan, and the fan of the heating air-conditioning fan does not rotate), the heating air-conditioning fan can independently turn on the heater 300 to heat the refrigerant in the heat conduction pipe 200 in the valley time period of power consumption at night, the heat insulation box 700 can effectively keep the heat of the refrigerant in the heat conduction pipe 200, and when the user turns on the heating function of the air-conditioning fan in the daytime, the air-conditioning fan can not turn on the heater 300, and firstly the heat in the heat conduction pipe 200 is transmitted to the heat dissipation pipe 100 to be dissipated, so that the energy-saving heating air-conditioning fan which consumes power at night and heats in the daytime is realized.
Moreover, the current air-conditioning fan with heating function mostly adopts the mode of directly blowing the electric heater by the fan, so that the electric heater is mostly exposed in the air when heating at high temperature, even when heating in the environment with high humidity, the entered moisture is easy to oxidize the electric heater to a certain extent, the heating efficiency of the electric heater is reduced, and the electric heater is seriously damaged.
The air conditioner fan heating device of this embodiment is through setting up heat pipe 200 and cooling tube 100 to be connected through trachea 400 and liquid pipe 500 between heat pipe 200 and the cooling tube 100 and form the circulation line, set up the refrigerant in the circulation line, the refrigerant in the heater 300 heating circulation line heats, no longer sets up the heater in ventilation channel, the heater does not receive the influence of moisture, has improved electric heater's work safety nature.
And, the air cooler described in this embodiment can be combined with the existing refrigeration type air cooler, and the water dew can not be condensed on the electric heater when the air cooler blows out the moisture, so that the electric heater can be prevented from being damaged. And the arrangement of the radiating pipe 100 also increases the contact area of the air conditioner fan and improves the heat exchange efficiency.
Meanwhile, the heat pipe 200 does not need to be installed in a ventilation passage, has a certain heat storage function, and can ensure that the refrigerant continues for a certain period of time under a certain high-temperature condition, and the interruption of the heating of the air conditioner fan cannot be caused in a short time after the heater 300 is turned off.

It should be noted that, in this embodiment, it is preferable that the heat conducting pipe 200 is located below the heat radiating pipe 100, and has a better matching degree with the air duct when being installed inside the air conditioning fan. When the design of the air conditioner fan requires that the heat dissipation pipe 100 and the heat conduction pipe 200 are horizontally disposed, or the heat dissipation pipe 100 is located above the heat conduction pipe 200, the air pipe 400 is provided with a circulation pump to drive the gaseous refrigerant in the air pipe 400 to flow.

And the arrangement of the radiating pipe 100 also increases the contact area of the air conditioner fan and improves the heat exchange efficiency.
Meanwhile, the heat pipe 200 does not need to be installed in a ventilation passage, has a certain heat storage function, and can ensure that the refrigerant continues for a certain period of time under a certain high-temperature condition, and the interruption of the heating of the air conditioner fan cannot be caused in a short time after the heater 300 is turned off.
Further, this embodiment also provides a method for controlling a heating air-conditioning fan according to any of the foregoing embodiments, including:
after receiving an air conditioner fan starting instruction, opening a throttle valve, acquiring an indoor temperature value, and controlling the opening of the throttle valve according to a set temperature value and the indoor temperature value.
Preferably, the controlling the opening degree of the throttle valve according to the set temperature value and the indoor temperature value includes:
calculating a first temperature difference value of a set temperature value and an indoor environment temperature value, determining a preset temperature interval in which the first temperature difference value falls, acquiring an opening signal corresponding to the preset temperature interval, and controlling the opening of the throttle valve according to the opening signal.
Specifically, a plurality of temperature preset intervals are preset in the air conditioner fan, each temperature preset interval corresponds to a different opening degree signal, and the different opening degree signals correspond to different opening degree values of the throttle valve.
Preferably, the larger the temperature value corresponding to the preset temperature interval is, the larger the opening value corresponding to the opening signal is.
For example, the preset interval has four intervals B1, B2, B3 and B4, wherein B1 is less than 0 ℃ (including 0 ℃), and the corresponding opening degree value p 1-20; b2 is 0 deg.C to 2 deg.C (excluding 0 deg.C and including 2 deg.C), corresponding to an opening value of p 1; b3 is 2 ℃ to 5 ℃ (excluding 2 ℃, including 5 ℃), corresponding to an opening value of p1+ 20; b4 is greater than 5 deg.C (excluding 5 deg.C), corresponding to an opening value of p1+ 50. It should be noted that the opening value p1 indicates that the opening value p1 of the throttle valve can make the indoor temperature stable around the set temperature during the heating process of the air conditioner fan, and the specific value is different for different types of air conditioner fans and different refrigerants.
When the judgment result is that the difference value between the current set temperature and the indoor environment temperature falls into the B4 interval, the throttle valve is controlled to operate at the opening degree of p1+50, so that the high-temperature gaseous refrigerant in the heat conduction pipe enters the heat dissipation pipe at a larger circulation amount, and the heating effect of the air-conditioning fan is improved. When the judgment result is that the difference value between the current set temperature and the indoor environment temperature falls into the interval B2, the throttle valve is controlled to operate at the opening degree of p1, so that the high-temperature gaseous refrigerant in the heat conduction pipe enters the heat dissipation pipe with relatively small flow, and the air conditioning fan is operated to maintain the indoor temperature at about the set temperature.
On the basis of the above embodiment, after the opening degree signal value is obtained, every time a first preset time period is set, calculating a second temperature difference value between the indoor environment temperature value after the first preset time period and the indoor environment temperature value before the first preset time period, where the second temperature difference value is a difference value between the indoor environment temperature value after the first preset time period and the indoor environment temperature value before the first preset time period, and determining whether the second temperature difference value is greater than a first preset temperature value T1, if so, maintaining the opening degree of the throttle valve; if not, acquiring a preset opening amplitude, and controlling the opening of the throttle valve to adjust the opening according to the preset opening amplitude.
For example, after the opening degree signal is obtained, a first preset time period is taken as 5min, every 5min interval, a second temperature difference value between an indoor environment temperature value after 5min and an indoor environment temperature value before 5min is calculated, whether the second temperature difference value is greater than a first preset temperature value T1 or not is judged, the first preset temperature value T1 can be a fixed value of 3 ℃, if the second temperature difference value is greater than 3 ℃, it is shown that the heating effect of the air conditioner fan is obvious, and the opening degree value of the throttle valve is maintained unchanged; and if the second temperature difference value is less than or equal to 3 ℃, the heating effect of the air conditioner fan is not obvious, the opening value of the throttle valve needs to be increased, and a preset opening amplitude value is increased on the basis of the previous opening value, wherein the preset opening amplitude value can be set to be 20.
Preferably, on the basis of the above embodiment, different temperature preset intervals correspond to different first preset temperature values T1, and after determining that the temperature that the first temperature difference value falls into is preset an interval, the first preset temperature value T1 that the temperature preset an interval corresponds is obtained, the temperature value that the temperature preset an interval corresponds is larger, and the first preset temperature value T1 is larger.
For example, the preset intervals include four intervals B1, B2, B3 and B4, the interval B1 is less than 0 ℃ (including 0 ℃), the corresponding opening value p1-20 is 5min, and the corresponding first preset temperature value T1 is-0.3 ℃; b2 is 0-2 deg.C (excluding 0 deg.C and including 2 deg.C), corresponding to an opening value p1, a first preset time period of 5min, and a corresponding first preset temperature value T1 of 0.3 deg.C; b3 is 2-5 ℃ (excluding 2 ℃ and including 5 ℃), corresponding to an opening value p1+20, a first preset time length is 5min, and corresponding to a first preset temperature value T1 is 0.5 ℃; b4 is greater than 5 deg.C (excluding 5 deg.C), corresponding to an opening value p1+50, a first preset time period of 5min, and corresponding to a first preset temperature value T1 of 0.8 deg.C.
Preferably, on the basis of the above embodiment, different temperature preset intervals correspond to different preset opening amplitudes, and after determining that the temperature in which the first temperature difference value falls is preset, the preset opening amplitude corresponding to the temperature preset interval is obtained, and the temperature value corresponding to the temperature preset interval is larger, and the preset opening amplitude is larger.
For example, the preset interval includes four intervals B1, B2, B3 and B4, where B1 is less than 0 ℃ (including 0 ℃), the corresponding opening value p1-20, the first preset time is 5min, the corresponding first preset temperature value T1 is-0.3 ℃, and the corresponding preset opening amplitude is-10; b2 is 0-2 ℃ (excluding 0 ℃ and including 2 ℃), the corresponding opening degree value p1 is 5min, the corresponding first preset temperature value T1 is 0.3 ℃, and the corresponding preset opening degree amplitude value is 10; b3 is 2-5 ℃ (excluding 2 ℃ and including 5 ℃), corresponding to the opening degree value p1+20, the first preset time is 5min, corresponding to the first preset temperature value T1 is 0.5 ℃, and corresponding to the preset opening degree amplitude value is 15; b4 is greater than 5 ℃ (excluding 5 ℃), corresponds to an opening value p1+50, has a first preset time period of 5min, corresponds to a first preset temperature value T1 of 0.8 ℃, and corresponds to a preset opening amplitude of 20.
Preferably, when the first temperature difference value falls into a temperature preset interval with the maximum corresponding temperature value and the throttle valve is increased to the maximum opening degree, judging whether the temperature of the inner pipe is smaller than a fifth preset temperature value or not, and if so, starting the heater; and if not, maintaining the opening degree of the throttle valve.
For example, when the first temperature difference value falls in the interval B4 and increases to the maximum opening degree of the throttle valve with the gradual adjustment of the opening degree of the throttle valve, it is determined whether the inner tube temperature is less than a fifth preset temperature value to detect whether the inner tube temperature meets the heating requirement. If the temperature of the inner pipe is lower than the fifth preset temperature value, the temperature of the inner pipe is not enough to heat, and a heater needs to be started to heat; if the temperature of the inner pipe is greater than or equal to the fifth preset temperature, the temperature of the inner pipe can meet the heating requirement, and the current maximum opening of the throttle valve is maintained for heating.
When the opening degree of the throttle valve is increased to the maximum opening degree, judging whether the temperature of the inner pipe is smaller than a fifth preset temperature value, wherein the fifth preset temperature value is a set temperature value of a lower level of heat released by a heat storage module preset in the air conditioner, and is 35 ℃ for example; when the temperature of the inner pipe is greater than or equal to a fifth preset temperature value, the indoor temperature can still be increased under the current opening degree of the throttle valve, and the heating control is quitted until the quitting condition is met; and when the temperature of the inner pipe is lower than the fifth preset temperature value, the heater is started to heat in time so as to ensure that the heating quantity and the heating speed meet the requirements of users.

step S200, the process proceeds to a heat accumulation control routine.
Specifically, the heat storage control program includes: acquiring a time value, judging whether the time value falls into a preset low-power time interval, if so, entering a heat storage mode, wherein the heat storage mode comprises a heater starting mode; if not, waiting for a second preset time period, then acquiring the time value again, and judging whether the time value falls into the preset low-power time interval or not until entering the heat storage mode.
Preferably, after entering the heat storage mode, the time value is acquired in real time, and when the acquired time value falls into a preset high-power time interval, the heat storage mode is exited.
Preferably, when the air conditioner fan starting command is received in the heat storage mode, the heat storage mode is also exited.
Specifically, receiving the shutdown instruction of the air conditioner fan means receiving the shutdown instruction sent by a user through a remote controller or an operation button, and after receiving the shutdown instruction, the air conditioner fan closes the fan and the throttle valve, so that the heat conduction pipe is in a closed state.
Specifically, the preset low power time interval refers to a preset power valley time period in the air conditioner fan memory. For example, in a certain area, the time period from the zero point of the morning to the 6 th point of the morning is the power consumption valley value time period, the electricity fee from the zero point of the morning to the 6 th point of the morning is low in 6 hours, and the electricity fee from the 6 th point of the morning to the next day is high in 18 hours, so that the time period from the zero point of the morning to the 6 th point of the morning can be recorded into the air conditioning fan, and the air conditioning fan acquires the time period information and determines the time period information as the preset low electricity time interval. In addition, the preset high-power time interval refers to a preset power peak time period in the air conditioner fan memory, and is determined as the preset high-power time interval if a time period of 18 hours from 6 am to the morning zero point of the next day is recorded in the air conditioner fan.
Preferably, the air-conditioning fan can be provided with a time setting program, and a user can input the time setting program through a mobile phone or a remote controller; optionally, the air conditioner fan may be configured to obtain the power consumption valley time period and the power consumption peak time period of the area through the internet of things after obtaining the positioning information, determine the obtained power consumption valley time period as a preset low power time interval, determine the obtained power consumption peak time period as a preset high power time interval, and enable automatic updating.
The heating air-conditioning fan control method of the embodiment closes the throttle valve after the air-conditioning fan is shut down, the air-conditioning fan automatically enters a heat storage control program, judges whether the air-conditioning fan is in a power consumption valley time period with low electric charge or not through time, and opens the heater for heat storage at the time with low electric charge, so that the heat stored in the heat conduction pipe is used for heating when the electric charge is higher in the daytime, and then the heater is opened for heating, thereby reducing the power consumption of users, reducing the power consumption in the peak time period, and improving the uniformity of regional power consumption.
Specifically, as shown in fig. 4, the method for controlling the heater to be turned on in the heat storage mode includes the following steps:
s210, acquiring a temperature value of an inner tube;

Specifically, the second preset temperature value T2 refers to a temperature value to which the refrigerant in the heat conduction pipe needs to be heated in a preset low-power time interval, for example, a heat storage level selected by a user through a remote controller or an operation button, where different heat storage levels correspond to different second preset temperature values T2. In this step, the second preset temperature value T2 is a fixed value preset by the air conditioner, such as 60 ℃
For example, the second preset temperature value T2 selected by the user is 60 ℃, the air-conditioning fan acquires an inner tube temperature value after entering the heat storage mode, and the heater is controlled to be turned on to store heat when the acquired inner tube temperature value is judged to be less than 60 ℃ and less than 60 ℃; when the temperature value of the inner pipe is greater than or equal to 60 ℃, judging whether the temperature value of the inner pipe is less than 60 ℃ again after 30 minutes, and circularly judging until the electric heating is started.
Preferably, after the heater is started, the temperature value of the inner tube is obtained in real time until the temperature value of the inner tube reaches or is greater than or equal to the fourth preset temperature value T4, the heater is turned off, the temperature value of the inner tube is obtained again at intervals of the fourth preset time length by taking the fourth preset time length as a period, and whether the temperature value of the inner tube is smaller than the fourth preset temperature value T4 is judged in a circulating manner until the heater is started.
In this embodiment, the fourth preset temperature value is a highest temperature value of the thermal storage module of the air conditioning fan, and if the highest temperature of the thermal storage module reaches 75 ℃, the heater and the thermal storage module are damaged if the heater is continuously turned on. After the heater is started, the temperature value of the inner tube is obtained in real time, whether the temperature value of the inner tube is increased to a fourth preset temperature value T4 is judged, the heater is timely turned off after the temperature value of the inner tube reaches a fourth preset temperature value T4, and the heating temperature of the heater is prevented from exceeding the heating demand of a user. And after the heater is turned off, the temperature value of the inner tube is obtained again after the fourth preset time interval, whether the temperature value of the inner tube is smaller than the second preset temperature value T2 is judged until the heater is turned on, automatic temperature monitoring is realized, and the temperature value of the inner tube of the air conditioner fan is ensured to be about the second preset temperature value T2 all the time.
For example, the second preset temperature value T2 selected by the user is 60 ℃, the fourth preset temperature value T4 is 75 ℃, the air-conditioning fan obtains the temperature value of the heat storage module after entering the heat storage mode, and controls the heater to be turned on to store heat when the obtained temperature value of the heat storage module is less than 60 ℃ and less than 60 ℃; and when the temperature value of the heat storage module is greater than or equal to 75 ℃, judging whether the temperature value of the heat storage module is less than 60 ℃ again after 30 minutes, and circularly judging until the electric heating is started. According to the embodiment, the heater is controlled to be turned on when the temperature is lower than 60 ℃ through autonomous temperature judgment, and is controlled to be turned off when the temperature reaches 75 ℃, so that the temperature of the heat storage module is always kept between 60 ℃ and 75 ℃.
Preferably, the temperature value of the inner tube in this embodiment is an average value of the temperatures of the refrigerants at a plurality of positions in the heat pipe, for example, the temperature values at 3 positions are taken at two ports and an intermediate position of the heat pipe, and the average value of the temperature values at 3 positions is calculated to determine the temperature value of the inner tube, so that the deviation of the temperature values of the inner tube caused by the difference of the temperatures at different positions in the heat pipe is prevented, and the accuracy of the judgment is improved.
Preferably, in the heating air-conditioning fan control method, even if the heat storage control program is already running, the heat storage control program is exited and the heating program is entered after the air-conditioning fan start-up command is received.

Specifically, after receiving an air conditioner fan opening instruction sent by a user, the throttle valve is opened, so that high-temperature refrigerant in the heat conduction pipe can evaporate high-temperature steam and flow through the heat dissipation pipe, and heating of the air conditioner fan is achieved. After the throttle valve is opened, acquiring an inner pipe temperature value, wherein the inner pipe temperature value is preferably an average value of the temperatures of the refrigerants at a plurality of positions in the heat conduction pipe; and determining whether to start the heater by judging whether the temperature value of the inner pipe is less than a third preset temperature value T3, forming a circulating judgment, and starting electric heating in time when the temperature value of the inner pipe is less than a third preset temperature value T3.
Specifically, the third predetermined temperature value T3 is the lowest temperature value at which the refrigerant in the heat pipe evaporates high-temperature steam, that is, when the temperature is below the third predetermined temperature value T3, the refrigerant does not evaporate high-temperature gas any more, and at this time, the electric heating needs to be started to ensure that the high-temperature refrigerant can evaporate gaseous refrigerant. The third preset temperature value T3 may be obtained through experiments according to the refrigerant characteristics and preset in the controller of the air conditioner fan.
Specifically, after the heater is started, the temperature value of the inner tube is obtained in real time, and the heater is turned off until the temperature value of the inner tube reaches or is greater than a fourth preset temperature value.
The fourth preset temperature value described in this embodiment refers to a highest temperature to which the refrigerant in the heat conducting pipe can be heated. In this embodiment, the fourth preset temperature value is a highest temperature value of the thermal storage module of the air conditioning fan, and if the highest temperature of the thermal storage module reaches 75 ℃, the heater and the thermal storage module are damaged if the heater is continuously turned on.
Specifically, the fourth preset temperature value is greater than the third preset temperature value T3.
Similarly, the fourth preset temperature value may be obtained through experiments according to the refrigerant characteristics and preset in the controller of the air conditioning fan.
