The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of illustrating the embodiments of the present invention and are not to be construed as limiting the embodiments of the present invention.
Referring to fig. 1 and 2, an air conditioner according to an embodiment of the present invention includes an air conditioning system and an air purifying system. The air purification system comprises a motor, the air conditioning system comprises a compressor, and the control method of the air conditioner comprises the following steps:
s10: detecting an absolute value of a temperature difference value between the indoor temperature and the outdoor temperature;
s20: detecting the rotating speed of the motor; and
s30: and adjusting the frequency of the compressor according to the absolute value of the temperature difference and the rotating speed of the motor.
Referring to fig. 2, an air conditioner 1000 according to an embodiment of the present invention includes an air conditioning system 100, an air purification system 200, a memory, and a processor. The air conditioning purification system 200 includes a motor 210, and the air conditioning system 100 includes a compressor 110, a memory storing at least one program, and a processor for executing the at least one program. As an example, the control method of the air conditioner according to the embodiment of the present invention may be implemented by the air conditioner 1000 according to the embodiment of the present invention, and may be applied to the air conditioner 1000.
Here, steps S10 to S30 of the control method of the air conditioner according to the embodiment of the present invention may be implemented by a processor. That is, the processor is used for executing a program to realize the detection of the absolute value of the temperature difference value between the indoor temperature and the outdoor temperature and the detection of the rotating speed of the motor; and adjusting the frequency of the compressor according to the absolute value of the temperature difference and the rotating speed of the motor.
Wherein the memory may be a stand-alone memory or a dedicated or dynamically allocated portion of the memory of the air conditioner. The processor may be a stand-alone processor or a dedicated or dynamically allocated portion of the processor of the air conditioner.
With the concern and demand of people on air quality, products with air purification functions such as independent air purifiers, fresh air systems and the like gradually enter daily life, however, generally, the air purification products are separated from the air conditioner, when the air purifiers and the air conditioner are used simultaneously, the air purifiers directly introduce outdoor air into a room, the refrigeration or heating effect of the air conditioner is affected to a certain degree, and the indoor temperature is not easy to be adjusted to the temperature required by a user.
The air conditioner 1000 according to the embodiment of the present invention includes an air conditioning system 100 and an air purification system 200, and the air conditioning system 100 and the air purification system 200 are integrally provided. For example, for a cabinet, the air conditioning system 100 may be located above the air purification system 200. Of course, the air conditioner 1000 may be an on-hook, and is not limited herein. The air conditioning system 100 is used for cooling or heating and includes a compressor 110. The air conditioning system 100 performs refrigeration, low-pressure vapor of the refrigerant is sucked by a compressor (not shown), compressed into high-pressure vapor and discharged to an outdoor heat exchanger (not shown), the outdoor heat exchanger is a condenser, and outdoor air sucked by an axial flow fan (not shown) of an outdoor fan flows through the outdoor heat exchanger to take away heat emitted by the refrigerant, so that the high-pressure refrigerant vapor is condensed into high-pressure liquid. The high pressure liquid passes through a filter (not shown) and a throttling mechanism (not shown) and then is sprayed into an indoor heat exchanger (not shown), wherein the indoor heat exchanger is an evaporator and is evaporated at a corresponding low pressure to absorb ambient heat. Meanwhile, the indoor fan sends the air which is cooled after releasing heat to the indoor through the air channel. Thus, the indoor air continuously circulates and flows to achieve the purpose of reducing the temperature or dehumidifying. The heating process of the air conditioning system 100 is the reverse of the cooling process. The air purification system 200 may be a new blower, which includes an air inlet, a filter screen, a blower, and a motor 210. The air inlet introduces outdoor fresh air, and the introduced air is filtered by the filter screen, wherein the filter screen can comprise an antibacterial and mildewproof primary filter screen, a sponge activated carbon layer, a honeycomb activated carbon layer and a high-efficiency filter screen. The motor 210 drives the fan to send out filtered air through the air duct. Therefore, indoor air can be purified, and the health of a user is facilitated.
The air conditioning system 100 operates to gradually approach the indoor temperature to the set temperature, and when the indoor temperature approaches the set temperature, in order to maintain the indoor temperature, the operating frequency of the compressor 110 may be adjusted according to the rotation speed of the motor 210 of the air purification system 200 or the air outlet speed of the air purification system 200 while introducing the outdoor air according to the temperature difference between the outdoor temperature and the indoor temperature, and it can be understood that, during the cooling operation, the outdoor temperature is usually higher than the indoor temperature, and after introducing the high-temperature outdoor air, the operating frequency of the compressor 110 needs to be increased to ensure the cooling effect, and the faster the rotation speed of the motor 210, the more the frequency of the compressor 110 increases. Similarly, when heating operation is performed, the outdoor temperature is usually lower than the indoor temperature, and after low-temperature outdoor air is introduced, the operating frequency of the compressor 110 needs to be increased to ensure the heating effect, and the faster the rotation speed of the motor 210 is, the more the frequency of the compressor 110 is increased.
In summary, according to the control method of the air conditioner and the air conditioner 1000 in the embodiments of the present invention, the frequency of the compressor 110 of the air conditioning system 100 is adjusted according to the temperature difference between the outdoor temperature and the indoor temperature and the rotation speed of the motor 210 of the air purification system 200, so that while the outdoor air is purified and introduced by the air purification system 200, the frequency of the compressor 110 of the air conditioning system 100 is adjusted to meet the adjustment requirement of the indoor temperature, the indoor temperature is ensured to quickly reach the user requirement, and the user experience is improved.
Referring to fig. 3 and 4, in some embodiments, when the air conditioning system 100 is in the cooling mode, the step S30 includes the steps of:
when the absolute value of the temperature difference is smaller than a first preset temperature difference and the rotating speed of the motor falls into a first rotating speed interval, controlling the frequency of the compressor to rise by a first frequency; or
And when the absolute value of the temperature difference is greater than or equal to a first preset temperature difference and the rotating speed of the motor falls into a first rotating speed interval, controlling the frequency of the compressor to rise by a fourth frequency.
In some embodiments, the processor is configured to execute at least one program to control the frequency of the compressor to increase by a first frequency when the absolute value of the temperature difference is less than a first predetermined temperature difference and the rotational speed of the motor falls within a first rotational speed interval; or
And when the absolute value of the temperature difference is greater than or equal to a first preset temperature difference and the rotating speed of the motor falls into a first rotating speed interval, controlling the frequency of the compressor to rise by a fourth frequency.
Specifically, the air conditioning system 100 further includes an indoor temperature sensor and an outdoor temperature sensor for sensing a current indoor temperature and an outdoor temperature.
Preferably, the first predetermined temperature difference is 6 ℃, the first rotation speed interval is 100-500rpm, the first frequency is 2Hz, and the fourth frequency is 4 Hz. It can be understood that, when the absolute value of the temperature difference is smaller than the first predetermined temperature difference, the outdoor temperature is closer to the indoor temperature, and the rotation speed of the motor 210 is lower, the amount of the outdoor air is less, the outdoor cooling effect is not greatly affected, and the operating frequency of the compressor 110 is properly increased.
Similarly, when the absolute value of the temperature difference is greater than or equal to the first predetermined temperature difference, the indoor temperature is lower, the outdoor temperature is higher, and the rotation speed of the motor 210 is lower, and the amount of outdoor air introduced is smaller, so that the operating frequency of the compressor 110 is properly increased, and compared to the embodiment in which the temperature difference is smaller than the first predetermined temperature difference, since the indoor temperature is already lower, it is necessary to produce more cooling capacity to maintain the cooling effect in the indoor, and the fourth frequency can be higher than the first frequency.
In such an embodiment, the control method further comprises the steps of:
when the absolute value of the temperature difference is smaller than the first preset temperature difference and the rotating speed of the motor falls into a second rotating speed interval, controlling the frequency of the compressor to rise by a second frequency; or
And when the absolute value of the temperature difference is greater than or equal to the first preset temperature difference and the rotating speed of the motor falls into the second rotating speed interval, controlling the frequency of the compressor to rise by a fifth frequency.
In some embodiments, the processor is configured to execute at least one program to control the frequency of the compressor to increase by a second frequency when the absolute value of the temperature difference is less than a first predetermined temperature difference and the rotational speed of the motor falls within a second rotational speed interval; or
And when the absolute value of the temperature difference is greater than or equal to the first preset temperature difference and the rotating speed of the motor falls into the second rotating speed interval, controlling the frequency of the compressor to rise by a fifth frequency.
Specifically, the rotation speed of the second rotation speed interval is greater than that of the first rotation speed interval, which is 501-1000 rpm. The second frequency is 4Hz greater than the first frequency. The fifth frequency is 8Hz greater than the fourth frequency. It can be understood that when the rotation speed of the motor 210 is higher, the amount of the introduced outdoor air is larger, and it is necessary to produce more cold to maintain the indoor cooling effect, so the second frequency is greater than the first frequency, and the fifth frequency is greater than the fourth frequency.
Further, in such an embodiment, the control method further comprises the steps of:
when the absolute value of the temperature difference is smaller than the first preset temperature difference and the rotating speed of the motor falls into a third rotating speed interval, controlling the frequency of the compressor to rise by a third frequency; or
And when the absolute value of the temperature difference is greater than or equal to the first preset temperature difference and the rotating speed of the motor falls into a third rotating speed interval, controlling the frequency of the compressor to rise by a sixth frequency.
In some embodiments, the processor is configured to execute at least one program to control the frequency of the compressor to increase by a third frequency when the absolute value of the temperature difference is less than the first predetermined temperature difference and the rotational speed of the motor falls within a third rotational speed interval; or
And when the absolute value of the temperature difference is greater than or equal to the first preset temperature difference and the rotating speed of the motor falls into a third rotating speed interval, controlling the frequency of the compressor to rise by a sixth frequency.
Specifically, the rotation speed of the third rotation speed interval is greater than the second rotation speed interval by 1001-. It can be understood that when the rotation speed of the motor 210 is further increased, the amount of the introduced outdoor air is further increased, and it is necessary to produce more cooling capacity to maintain the indoor cooling effect, so that the third frequency is greater than the second frequency, and the sixth frequency is greater than the fifth frequency.
It should be noted that the operation frequency of the compressor 110 after increasing the frequency should be less than or equal to the maximum frequency that the compressor 110 is allowed to operate, and if the value after increasing the frequency is higher than the maximum frequency, the compressor 110 is directly operated at the maximum frequency.
It should be noted that the values of the increase of the predetermined temperature difference, the rotation speed of the motor and the operating frequency of the compressor are not limited to the values disclosed in the above embodiments.
Referring to fig. 5 and 6, in some embodiments, when the air conditioning system 100 is in heating operation, step S30 includes:
when the absolute value of the temperature difference is smaller than a second preset temperature difference and the rotating speed of the motor falls into a first rotating speed interval, controlling the frequency of the compressor to rise by a seventh frequency; or
And when the absolute value of the temperature difference is greater than or equal to a second preset temperature difference and the rotating speed of the motor falls into the first rotating speed interval, controlling the frequency of the compressor to rise by a tenth frequency.
In some embodiments, the processor is configured to execute at least one program to control the compressor frequency to increase by a seventh frequency when the absolute value of the temperature difference is less than a second predetermined temperature difference and the rotation speed of the motor falls within a first rotation speed interval; or
And when the absolute value of the temperature difference is greater than or equal to a second preset temperature difference and the rotating speed of the motor falls into the first rotating speed interval, controlling the frequency of the compressor to rise by a tenth frequency.
Preferably, the second predetermined temperature difference is 10 ℃, the first rotation speed range is 100-500rpm, the seventh frequency is 3Hz, and the fourth frequency is 5 Hz. It can be understood that, when the absolute value of the temperature difference is smaller than the second predetermined temperature difference, the outdoor temperature is closer to the indoor temperature, and the rotation speed of the motor 210 is lower, the amount of the outdoor air is less, the effect of the outdoor heating is not greatly affected, and the operating frequency of the compressor 110 is only increased appropriately.
Similarly, when the absolute value of the temperature difference is greater than or equal to the second predetermined temperature difference, the indoor temperature is higher, the outdoor temperature is lower, and the rotation speed of the motor 210 is lower, and the amount of outdoor air introduced is smaller, so that the operating frequency of the compressor 110 is appropriately increased, and compared to the embodiment in which the temperature difference is smaller than the first predetermined temperature difference, since the indoor temperature is already higher, it is necessary to make more heat to maintain the heating effect in the room, and the tenth frequency may be higher than the seventh frequency.
In such an embodiment, step S20 includes:
when the absolute value of the temperature difference is smaller than a second preset temperature difference and the rotating speed of the motor falls into a second rotating speed interval, controlling the frequency of the compressor to rise by an eighth frequency; or
And when the absolute value of the temperature difference is greater than or equal to a second preset temperature difference and the rotating speed of the motor falls into a second rotating speed interval, controlling the frequency of the compressor to rise by an eleventh frequency.
In some embodiments, the processor is configured to execute at least one program to control the frequency of the compressor to increase by an eighth frequency when the absolute value of the temperature difference is less than a second predetermined temperature difference and the rotational speed of the motor falls within a second rotational speed interval; or
And when the absolute value of the temperature difference is greater than or equal to a second preset temperature difference and the rotating speed of the motor falls into a second rotating speed interval, controlling the frequency of the compressor to rise by an eleventh frequency.
Specifically, the rotation speed of the second rotation speed interval is greater than the rotation speed of the first rotation speed interval, which is 501-1000 rpm. The eighth frequency is 6Hz greater than the seventh frequency and the eleventh frequency is 8Hz greater than the tenth frequency. It can be understood that when the rotation speed of the motor 210 is higher, the amount of the introduced outdoor air is larger, and it is necessary to make a larger amount of heat to maintain the heating effect in the room, so that the eighth frequency is greater than the seventh frequency, and the eleventh frequency is greater than the tenth frequency.
Further, in such an embodiment, the control method further comprises the steps of:
when the absolute value of the temperature difference is smaller than the second preset temperature difference and the rotating speed of the motor falls into a third rotating speed interval, controlling the frequency of the compressor to increase by a ninth frequency; or
And when the absolute value of the temperature difference is greater than or equal to the second preset temperature difference and the rotating speed of the motor falls into the third rotating speed interval, controlling the frequency of the compressor to rise by a twelfth frequency.
In some embodiments, the processor is configured to execute at least one program to control the frequency of the compressor to increase by a ninth frequency when the absolute value of the temperature difference is less than the second predetermined temperature difference and the rotation speed of the motor falls within a third rotation speed interval; or
And when the absolute value of the temperature difference is greater than or equal to the second preset temperature difference and the rotating speed of the motor falls into the third rotating speed interval, controlling the frequency of the compressor to rise by a twelfth frequency.
Specifically, the rotation speed of the third rotation speed interval is greater than the second rotation speed interval by 1001-1500rpm, the ninth frequency is greater than the eighth frequency by 9Hz, and the twelfth frequency is greater than the eleventh frequency by 12 Hz. It can be understood that when the rotation speed of the motor 210 is further increased, the amount of the introduced outdoor air is further increased, and it is required to make a larger amount of heat to maintain the heating effect in the room, so that the ninth frequency is greater than the second frequency, and the sixth frequency is greater than the fifth frequency.
It should be noted that the operation frequency of the compressor 110 after increasing the frequency should be less than or equal to the maximum frequency that the compressor 110 is allowed to operate, and if the value after increasing the frequency is higher than the maximum frequency, the compressor 110 is directly operated at the maximum frequency.
It should be noted that the values of the increase of the predetermined temperature difference, the rotation speed of the motor and the operating frequency of the compressor are not limited to the values disclosed in the above embodiments.
