Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
In winter, air conditioners are often used for heating, and when heating is performed, outdoor air is sucked into an air duct from an air inlet, and then heat is transferred to liquid refrigerant which is depressurized by an expansion valve and flows into an evaporator coil. The refrigerant after absorbing heat is compressed by the compressor and flows back to the evaporator of the indoor unit, so that heat is transferred to indoor cold air, and the indoor temperature is raised.
When the outdoor temperature is low, moisture in the air is condensed into frost on the outdoor unit of the air conditioner. As the running time of the air conditioner is prolonged, the thickness of frost formed on the outdoor unit of the air conditioner is increased, and the performance of the heat exchanger of the air conditioner is gradually reduced, and the heating effect is also reduced.
In the prior art, when the air conditioner is manually shut down, if the outdoor unit of the air conditioner is frosted more, the frost can be remained on the heat exchanger of the outdoor unit at the moment and changed into ice from the frost, so that the heating effect after restarting is affected, and the ice can not be completely removed during defrosting again, so that the heating effect is affected.
So this application is through providing one kind and carrying out the defrosting control mode of forcing the defrosting when shutting down, avoids outer quick-witted frosting to influence the heating effect of air conditioner next time, improves user's use experience and comfort level.
Next, the technical solutions shown in the present application will be described in detail through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and for the same or similar content, the description will not be repeated in different embodiments.
Next, how the defrosting control method provided in the embodiment of the present application controls the air conditioner to perform forced defrosting will be described with reference to fig. 1.
Fig. 1 is a schematic flow chart of a defrosting control method according to an embodiment of the present application. As shown in fig. 1, the method includes:
s101, acquiring an air conditioner operation mode when the acquired air conditioner remote control signal is a shutdown signal.
In the step, the air conditioner can automatically defrost when the frosting thickness meets a certain condition. When the air conditioner is turned off manually, the automatic defrosting of the air conditioner is affected, and the next heating effect is affected by the frost on the external machine, so that a forced defrosting step is added when the air conditioner is turned off manually. Therefore, when the received air conditioner remote controller signal is a shutdown signal, the operation mode of the air conditioner is acquired, wherein the operation mode of the air conditioner comprises a heating mode or a refrigerating mode.
S102, when the air conditioner operation mode is a heating mode, acquiring the external environment temperature and the operation state of the air conditioner, wherein the operation state of the air conditioner comprises the current coil temperature and/or the operation time after the last defrosting program is finished.
In this step, when the air conditioner is in the heating mode, the external environment temperature and the operation state of the air conditioner affect the frosting of the air conditioner, and the operation state of the air conditioner includes: current coil temperature and/or run time since the end of the last defrost procedure. Therefore, when the air conditioner signal is a shutdown signal and the operation mode is a heating mode, the outside environment temperature and the operation state of the air conditioner at the moment are acquired.
And S103, when the external environment temperature is smaller than a first preset temperature Ta, determining whether to forcedly defrost the air conditioner according to the running state.
In this step, the first preset temperature Ta is an external environment temperature at which the air conditioner external unit can generate frost, and when the external environment temperature is less than the first preset temperature Ta, it is determined that the air conditioner external unit may generate frost at the current external environment temperature. The first preset temperature Ta is typically 7-10 ℃, and the specific value is determined according to practical situations.
Therefore, when the external environment temperature is smaller than the first preset temperature, judging whether to forcedly defrost the air conditioner according to the magnitude relation between the running state of the air conditioner and the preset value. The preset value is not limited in this embodiment.
And S104, if the forced defrosting of the air conditioner is determined, controlling the air conditioner to perform forced defrosting, and controlling the air conditioner to be powered off after the forced defrosting.
In the step, when the forced defrosting of the air conditioner is determined, the fan is controlled to be closed, the compressor is started, and the compressor is stopped until the air conditioner exits the forced defrosting.
Specifically, the fan is turned off, then the flow direction of the refrigerant is switched through the four-way reversing valve, namely, the air conditioner works in a refrigerating state, the compressor is started, the discharged high-temperature and high-pressure refrigerant enters the external heat exchanger, and frost on the surface of the external heat exchanger is melted in a gasification heat dissipation mode, so that the defrosting purpose is achieved. And after the forced defrosting is finished, executing a shutdown signal to control the air conditioner to shut down. The present embodiment does not make any limitation on how to determine the end of defrosting of the air conditioner, and it is possible to determine whether the defrosting of the air conditioner is ended by the coil temperature or the defrosting time, for example.
The application provides a defrosting control method, when an air conditioner remote controller signal is power-off and an operation mode is a heating mode, the external environment temperature and the operation state of an air conditioner are obtained, when the external environment temperature is smaller than a first preset temperature Ta, whether the air conditioner is controlled to perform forced defrosting is judged according to the operation state, and the air conditioner is controlled to be powered off after forced defrosting. Through the mode, a step of forced defrosting is added after the air conditioner is manually shut down, so that the phenomenon that frost on an external machine influences the next heating effect of the air conditioner after the air conditioner is manually shut down due to the fact that defrosting conditions are not achieved is avoided, and the use experience and comfort level of a user are improved.
Next, how to determine whether the air conditioner satisfies the forced defrosting condition by using the defrosting control method according to the embodiment of the present application will be described with reference to fig. 2.
Fig. 2 is a second flowchart of a defrosting control method according to an embodiment of the present application. As shown in fig. 2, the method includes:
s201, acquiring the magnitude relation between the running time and the first preset time and the second preset time;
in the step, the first preset time and the second preset time are used for judging the possibility of frost generation of the air conditioner, the first preset time is smaller than the second preset time, and the air conditioner does not generate frost when the running time is smaller than the first preset time; the air conditioner is longer than the second preset time, and frost is generated by the air conditioner. Therefore, the size relation between the running time and the first preset time and the second preset time is obtained, and whether the air conditioner is controlled to perform forced defrosting is determined according to the size relation.
When the air conditioner runs for about 45-60 minutes, the air conditioner can automatically defrost, so that the first preset time and the second preset time are required to be set within 45 minutes, the first preset time and the second preset time are required to be determined according to actual conditions, and the embodiment is not limited in any way. Illustratively, the first preset time may be 15 minutes and the second preset time may be 30 minutes.
S202, when the running time is greater than or equal to a first preset time and less than a second preset time, acquiring the magnitude relation between the current coil temperature Tc and the second preset temperature Tc 1.
When the running time of the air conditioner is greater than or equal to the first preset time and less than the second preset time, the air conditioner external unit may generate frost, and whether the frost is generated or not needs to be judged by other factors. The coil temperature can be directly obtained, so that the relationship between the coil temperature and the second preset temperature Tc1 is obtained to judge whether the air conditioner is controlled to defrost.
And S203, if the current coil temperature Tc is smaller than a second preset temperature Tc1, determining to forcibly defrost the air conditioner.
In this step, the second preset temperature is a critical coil temperature for generating frost, and the temperature can be obtained through experimental simulation, and the embodiment does not limit how to obtain the temperature. The second preset temperature is generally-3-5 ℃, and the specific value of the second preset temperature is determined according to actual conditions. And when the current coil temperature Tc is smaller than the second preset temperature Tc1, determining to forcibly defrost the air conditioner.
S204, when the running time is greater than or equal to the second preset time, determining to forcibly defrost the air conditioner.
In the step, when the acquired running time of the air conditioner is greater than or equal to the second preset time, the air conditioner is considered to generate frost certainly, and the forced defrosting of the air conditioner is judged to be needed.
And S205, when the running time is smaller than the first preset time, controlling the air conditioner to be turned off.
In this step, when the running time is less than the first preset time, it is considered that frost is not generated in the current working condition of the air conditioner, so that it is determined that defrosting of the air conditioner is not needed at this time, and the air conditioner is controlled to be turned off directly according to the signal of the air conditioner remote controller.
The application provides a defrosting control method, which is used for judging whether to force defrosting of an air conditioner according to the magnitude relation between the running time and a first preset time and a second preset time and the magnitude relation between the current coil temperature and a second preset temperature. By the mode, whether the current working condition of the air conditioner generates frost or not is comprehensively judged by a plurality of factors, so that the frost prevention judgment is more accurate, and the defrosting effect of the air conditioner is improved.
How the defrosting control method provided in the embodiment of the present application controls the air conditioner to exit the forced defrosting is described below with reference to fig. 3.
Fig. 3 is a flowchart illustrating a defrosting control method according to an embodiment of the present application. As shown in fig. 3, the method includes:
s301, controlling the air conditioner to perform forced defrosting, and continuously acquiring a new coil temperature.
S302, acquiring the magnitude relation between the coil temperature and a third preset temperature in a third preset time.
And S303, if the temperature of the coil is higher than the third preset temperature, controlling the air conditioner to be shut down when the temperature of the coil reaches the third preset temperature.
S304, if the temperature of the coil is smaller than or equal to a third preset temperature, controlling the air conditioner to be shut down after the third preset time is over.
In the steps S301 to S304, the third preset time is an average defrosting time when the air conditioner automatically performs defrosting, and it may be considered that the forced defrosting is completed when the forced defrosting time is equal to or longer than the third preset time. The third preset time is generally 9-11 minutes, the specific value is determined according to the actual situation, and the embodiment does not limit how to determine the third preset time.
When the air conditioner is shut down manually, the frosting thickness of the air conditioner outdoor unit cannot meet the requirement of automatic defrosting, and the frosting thickness is in direct proportion to the defrosting time, namely, the thicker the frosting is, the longer the defrosting time is needed. Therefore, the air conditioner may also end the defrosting and exit the forced defrosting within the third preset time.
Because the coil temperature is directly readable, when the forced defrosting is performed, continuously acquiring a new coil temperature in a third time, and judging whether to exit the forced defrosting or not according to the magnitude relation between the new coil temperature and a third preset temperature.
The third preset temperature is a critical coil temperature after defrosting of the air conditioner is completed, and the third preset temperature can be obtained through experimental simulation. The third preset temperature is generally 9-12 ℃, and the specific value is determined according to the actual situation. And when the temperature of the new coil pipe is higher than the third preset temperature, the defrosting of the air conditioner is considered to be finished, and the air conditioner is controlled to exit the forced defrosting and is shut down. Otherwise, after the third preset time is over, controlling the air conditioner to exit the forced defrosting and shutting down.
By the mode, whether the air conditioner is controlled to exit the forced defrosting is judged by the forced defrosting time and the temperature of the coil pipe, and the energy waste is avoided on the basis of guaranteeing the defrosting effect of the air conditioner external unit.
