In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present application, and are not of specific significance per se. Thus, "module" and "component" may be used in combination.
In order to solve the problems mentioned in the background art, according to an aspect of the embodiments of the present application, there is provided an embodiment of a heating method of an air conditioner. As shown in fig. 1, the method may include the steps of:
step S102, when the air conditioner is in heating operation, determining whether the intelligent power module is in a safe temperature range;
Step S104, when the intelligent power module operates in the safe temperature range, a first current limit value and an outdoor environment temperature of the air conditioner are obtained, wherein the first current limit value is an overcurrent protection current value preset for refrigerating operation of the air conditioner under the condition that the outdoor environment temperature is greater than or equal to the first temperature;

And S108, controlling the heating operation of the air conditioner by taking the second current limit value as an overcurrent protection current value of the heating operation of the air conditioner at the current outdoor environment temperature.
Through the steps S102 to S108, the application reasonably corrects the overcurrent protection limit value of the alternating current preset by the air conditioner according to the temperature of the intelligent power module and the outdoor environment temperature, avoids the condition of insufficient heat exchange capacity, improves the heating quantity, ensures the heating effect of the air conditioner, improves the comfort of the inner side temperature, and solves the technical problem that the heat exchange capacity is insufficient because the unit is easy to limit frequency due to the AC current value under the low-temperature and ultra-low-temperature heating conditions.
The technical scheme of the application can be applied to heating control of the air conditioner, and particularly can be applied to heating control of the air conditioner in low-temperature and ultra-low-temperature environments. In the embodiment of the application, the low temperature can be 0 to 7 ℃, and the ultralow temperature can be a temperature range lower than 0 ℃. The following describes the technical scheme of the present application in detail with reference to the complete heating process shown in fig. 2.
In step S102, it is determined whether the intelligent power module (IPM module) operates in a safe temperature range in order to detect whether the intelligent power module is damaged. Normally, when the ambient temperature is less than 35 degrees celsius, the temperature of the IPM module should be less than 80 degrees celsius, and the maximum temperature is not more than 95 degrees celsius. This is to ensure that the IPM module is not degraded or damaged under normal operating conditions.
In an alternative embodiment, the determining whether the smart power module is operating within the safe temperature range includes:
Step 1, acquiring a first maximum safe temperature of the intelligent power module under a standard working condition, a correction value corresponding to the intelligent power module under the current outdoor environment temperature and the current module temperature of the intelligent power module.
In the embodiment of the present application, as shown in fig. 2, the first maximum safe temperature T is set to be the highest temperature at which the intelligent power module can safely operate under the standard working condition. The correction value Δt is a value adjusted according to the outdoor environment temperature for calculating the maximum safe temperature of the intelligent power module at the current outdoor environment temperature. The current module temperature is the current actual operating temperature of the intelligent power module.
And step 2, calculating a second maximum safe temperature of the intelligent power module under the current outdoor environment temperature according to the corrected value of the first maximum safe temperature.
In the embodiment of the present application, as shown in fig. 2, the second maximum safe temperature is the highest temperature at which the intelligent power module can safely operate under the current outdoor environment temperature, i.e., T is set to Δt.
Step 3, if the module temperature is less than or equal to the second maximum safe temperature, determining that the intelligent power module operates in the safe temperature range; and if the module temperature is greater than the second maximum safe temperature, determining that the intelligent power module is not operated in the safe temperature range.
In the embodiment of the application, if the module temperature is less than or equal to the second maximum safe temperature, the intelligent power module can be determined to operate in a safe temperature range, and the working temperature of the intelligent power module is safe. If the module temperature is greater than the second maximum safe temperature, it may be determined that the intelligent power module is not operating within the safe temperature range, and its operating temperature exceeds the safe limit, which may result in equipment damage or performance degradation. In this case, some measures need to be taken to reduce the operating temperature of the intelligent power module, such as increasing the heat sink, reducing the workload, etc.
In step S102, the first current limit value is an overcurrent protection current value preset for the air conditioner in the cooling operation under the condition that the outdoor ambient temperature is greater than or equal to the first temperature, where the condition that the temperature is greater than or equal to the first temperature refers to a severe high temperature condition, such as 35 degrees celsius and above. At present, an AC current (alternating current) protection function is adopted for an air conditioner to ensure that a unit can reliably operate, and an overcurrent value is usually set according to severe high-temperature refrigeration conditions, so that the surface temperature rise value of a main board component can be ensured to be within a safe range, but the limitation does not distinguish refrigeration and heating, particularly under low-temperature and ultra-low-temperature heating conditions, the operation frequency of a compressor is rapidly increased due to severe outdoor environment temperature, the current value is increased, and the unit is easy to limit frequency due to the AC current value and has insufficient heat exchange capacity.
In an alternative embodiment, said adjusting said first current limit according to said outdoor ambient temperature value, resulting in a second current limit comprises:
When the outdoor environment temperature is greater than or equal to a second temperature, taking the first current limit value as the second current limit value, wherein the second temperature is smaller than the first temperature;
When the outdoor environment temperature is smaller than the second temperature and larger than or equal to a third temperature, multiplying the first current limit value by a first correction coefficient to obtain the second current limit value;
When the outdoor environment temperature is smaller than the third temperature and larger than or equal to the fourth temperature, multiplying the first current limit value by a second correction coefficient to obtain the second current limit value;
When the outdoor environment temperature is smaller than the fourth temperature and larger than or equal to the fifth temperature, multiplying the first current limit value by a third correction coefficient to obtain the second current limit value;
and when the outdoor environment temperature is smaller than the fifth temperature and larger than or equal to the sixth temperature, multiplying the first current limit value by a fourth correction coefficient to obtain the second current limit value.
In the embodiment of the present application, as shown in fig. 2, the second temperature T0, the third temperature T1, the fourth temperature T2, the fifth temperature T3, and the sixth temperature T4 may be 7 degrees celsius, 2 degrees celsius, 0 degrees celsius, -7 degrees celsius, and-15 degrees celsius in order. The first, second, third and fourth correction coefficients K1, K2, K3 and K4 may be 1.05, 1.1, 1.2 and 1.3 in order. It can be seen that no modification of the first current limit is required when the outdoor ambient temperature is greater than 7 degrees celsius, and that the magnitude of the modification is greater when the temperature is lower. The specific temperature division and correction factor setting can be set according to actual requirements. Wherein I is set to be a first current limit value, and specifically the first current limit value is an overcurrent protection current value of an AC current (alternating current) of the air conditioner in a cooling operation under a condition that an outdoor ambient temperature is greater than or equal to a first temperature.
In an optional embodiment, after the controlling the heating operation of the air conditioner by using the second current limit value as an overcurrent protection current value of the heating operation of the air conditioner at the current outdoor environment temperature, the method further includes:
step 1, acquiring the initial operating frequency of the air conditioner corresponding to the current outdoor environment temperature;
Step 2, determining a correction value of the initial operating frequency according to the outdoor environment temperature;
Step 3, adjusting the initial operating frequency according to the correction value to obtain a target operating frequency;
And 4, controlling the air conditioner to operate according to the target operating frequency.
In the embodiment of the application, after the limit value of the alternating current is adjusted, the operation frequency of the compressor can be properly adjusted according to the outdoor environment temperature in order to further enhance the inner side heat exchange capability. Specifically, the step of adjusting the initial operating frequency according to the correction value to obtain a target operating frequency includes:
when the outdoor environment temperature is greater than or equal to a second temperature, taking a first initial operating frequency as the target operating frequency;
when the outdoor ambient temperature is less than the second temperature and greater than or equal to a third temperature, taking the sum of a second initial operating frequency and a first correction value as the target operating frequency;
When the outdoor ambient temperature is less than the third temperature and greater than or equal to a fourth temperature, taking the sum of a third initial operating frequency and a second correction value as the target operating frequency;
when the outdoor ambient temperature is less than the fourth temperature and greater than or equal to a fifth temperature, taking the sum of a fourth initial operating frequency and a third correction value as the target operating frequency;
And when the outdoor environment temperature is smaller than the fifth temperature and larger than or equal to the sixth temperature, taking the sum of the fifth initial operating frequency and the fourth correction value as the target operating frequency.
In the embodiment of the present application, as shown in fig. 2, when the outdoor ambient temperature is greater than 7 degrees celsius, there is no need to correct the first initial operating frequency F0 of the compressor, and when the outdoor ambient temperature is less than 7 degrees celsius and greater than or equal to 2 degrees celsius, the corrected target operating frequency is F1 (the second initial operating frequency) +Δf1 (the first correction value) corresponding to the current temperature interval, and similarly, when the outdoor ambient temperature is less than 2 degrees celsius and greater than or equal to 0 degrees celsius, the corrected target operating frequency is f2+Δf2, when the outdoor ambient temperature is less than 0 degrees celsius and greater than or equal to-7 degrees celsius, the corrected target operating frequency is f3+Δf3, and when the outdoor ambient temperature is less than-7 degrees celsius and greater than or equal to-15 degrees celsius, the corrected target operating frequency is f4+Δf4. Wherein, F0 < F1 < F2 < F3 < F4 can be 70Hz, 90Hz, 100Hz, 105Hz, 110Hz, delta F1 > -delta F2 > -delta F3 > -delta F4 > 0, and the frequency increase can be 8Hz, 6Hz, 4Hz, 2Hz.
In an alternative embodiment, the method further comprises:
Step 1, acquiring the tube temperature of an outdoor evaporation side tube;
step 2, determining whether to enter a defrosting state according to the tube temperature of the outdoor evaporation side tube;
Step 3, if the defrosting state is entered, the first current limit value is adjusted according to a preset defrosting configuration, and a third current limit value is obtained;
And 4, taking the third current limit value as an overcurrent protection current value of the air conditioner in heating operation in a defrosting state to control the heating operation of the air conditioner.
In the embodiment of the application, the outdoor evaporation side pipe refers to a copper pipe for heat exchange in an air conditioner outdoor unit. It is typically installed in an outdoor environment to exchange heat with indoor units to absorb or release heat. In an air conditioning system, an outdoor evaporation side pipe generally works together with an assembly of an outdoor fin, a fan, etc., and sucks in outdoor air and exchanges heat with a refrigerant. In this way, the outdoor evaporation side pipe can transfer the cooling capacity of the refrigerant to the outdoor air, thereby achieving a cooling effect.
In the embodiment of the application, the air conditioner can adjust the overcurrent protection current value according to the pipe temperature of the outdoor evaporation side pipe in the unstable heating defrosting and the stable heating defrosting processes. When the temperature of the outdoor evaporation side pipe is lower than minus 6 ℃ and the duration exceeds 5 minutes, and the accumulated running time of the compressor exceeds 45 minutes, and the temperature of the indoor coil pipe is lower than 48 ℃, the air conditioner enters an unsteady state for heating and defrosting. At this time, the outdoor unit stops absorbing heat, the indoor unit is switched to a refrigerating mode, the four-way valve is switched to change, the outdoor heat exchanger radiates heat to the outside, and defrosting is started. When the temperature of the outdoor evaporation side pipe gradually rises to more than 0 ℃ or the defrosting time reaches the set maximum defrosting time (for example, 10 minutes), the air conditioner exits the defrosting state and enters the steady-state heating state. At this time, the four-way valve commutates again, and the indoor and outdoor units recover the heating mode. And when the air conditioner enters a defrosting state, the first current limit value is adjusted according to a preset defrosting configuration to obtain a third current limit value, and the third current limit value is used as an overcurrent protection current value of the air conditioner heating operation in the defrosting state to control the air conditioner heating operation, so that defrosting frequency is improved, and defrosting cleanliness is guaranteed.
The application reasonably corrects the overcurrent protection limit value of the alternating current preset by the air conditioner according to the temperature of the intelligent power module and the outdoor environment temperature, avoids the condition of insufficient heat exchange capacity, improves the heating quantity, ensures the heating effect of the air conditioner, improves the comfort of the inner side temperature, and solves the technical problem that the heat exchange capacity is insufficient because the unit is easy to limit the frequency due to the AC current value under the low-temperature and ultralow-temperature heating conditions.
