Referring to fig. 2, in a first embodiment, the present invention provides a heating control method of an air conditioning system, including:
step S1, acquiring the coil temperature of the indoor heat exchanger when the air conditioning system operates in a heating mode;
in this embodiment, when the air conditioning system is in the heating mode, the coil temperature of the indoor heat exchanger can be obtained in real time or at regular time, wherein the coil temperature of the indoor heat exchanger is preferably the intermediate coil temperature, in other embodiments, the coil temperature of the indoor heat exchanger can also be the outlet temperature of the indoor heat exchanger, and specifically, the position for detecting the coil temperature can be reasonably selected according to actual needs.
Step S2, selecting a corresponding wind speed gear and/or frequency gear to operate according to the temperature interval of the coil temperature of the indoor heat exchanger;
in this embodiment, the present invention is particularly suitable for the case where the air conditioning system performs heating when the external environment temperature is low, and therefore, when the air conditioning system operates in the heating mode, the detected coil temperature of the indoor heat exchanger gradually increases from a low temperature to a high temperature. Therefore, in order to improve the heating efficiency of the air-conditioning system, the indoor fan of the air-conditioning system can be controlled to operate at a high-grade wind speed, when the temperature of the coil pipe rapidly rises to a preset critical temperature, the indoor fan can be controlled to operate at a low-grade wind speed, and finally when the temperature of the coil pipe is stabilized within a preset temperature range, the indoor fan is controlled to operate at a medium-grade wind speed; and/or controlling the compressor to operate at a high-grade frequency, controlling the compressor to operate at a low-grade frequency when the temperature of the coil pipe rapidly rises to a preset critical temperature, and finally controlling the compressor to operate at a medium-grade wind speed when the temperature of the coil pipe is stabilized within a preset temperature range. Therefore, the heating capacity of the air conditioning system can be obviously improved, and the heating effect in a low-temperature environment is improved.
In other embodiments, for the case that the external environment temperature is not particularly low, when the air conditioning system operates in the heating mode, the detected temperature of the coil of the indoor heat exchanger is relatively high, and at this time, the indoor fan can be directly controlled to operate at the low-grade wind speed without operating at the high-grade wind speed first and then at the low-grade wind speed in the control manner as described above; it is also not necessary to control the compressor to operate at the high range frequency and then the low range frequency as described above, but the compressor may be directly controlled to operate at the low range frequency.
Similarly, when the coil temperature of the indoor heat exchanger detected by the air conditioning system is just in the preset temperature range, the indoor fan can be directly controlled to operate at the medium-grade wind speed, and/or the compressor can be directly controlled to operate at the medium-grade frequency.
And step S3, controlling an indoor fan of the air conditioning system to operate in a medium-frequency gear and/or controlling a compressor to operate in a medium-frequency gear until the coil temperature is less than or equal to the first temperature and greater than or equal to the second temperature for a preset time.
In this embodiment, as described above, the coil temperature T is not directly lower than or equal to the first temperature T1And is greater than or equal to the second temperature T2Or by wind speed or frequency adjustment, such that the coil temperature is less than or equal to a first temperature and greater than or equal to a second temperature, provided that it is detected that the coil temperature is less than or equal to the first temperature and greater than or equal to the second temperature, T2＜T＜T1And when the temperature is more than 20 ℃ and less than 30 ℃ and the preset time lasts for 5min, controlling an indoor fan of the air conditioning system to operate in a medium-frequency gear and/or controlling a compressor to operate in a medium-frequency gear so as to improve the heating capacity of the air conditioning system in the heating mode to the maximum extent. It should be understood that the specific values of the first temperature and the second temperature can be reasonably set according to actual needs, and the above specific examples are only used for helping understanding the scheme of the present invention and do not have a limiting effect.
According to the heating control method of the air conditioning system, when the air conditioning system operates in a heating mode, the temperature of a coil of an indoor heat exchanger is obtained, then a corresponding wind speed gear and/or frequency gear is selected to operate according to a temperature interval where the temperature of the coil of the indoor heat exchanger is located, and until the temperature of the coil is less than or equal to a first temperature and greater than or equal to a second temperature for a preset time, an indoor fan of the air conditioning system is controlled to operate in a medium-frequency gear and/or a compressor is controlled to operate in a medium-frequency gear. Therefore, the problem that the heating effect of the air conditioning system is poor in the low-temperature environment can be solved, the heating quantity of the air conditioning system in the heating mode is improved to the maximum extent, and therefore user experience is improved.
In the second embodiment, referring to fig. 3, based on the first embodiment, the step S2 includes:
step S21, when the temperature of the coil pipe is less than or equal to the second temperature, controlling the indoor fan to operate at a high-wind gear and/or controlling the compressor to operate at a high-frequency gear;
in this embodiment, the temperature of the coil detected by the air conditioning system is less than or equal to the second temperature T2If the temperature is 20 ℃, the air conditioning system is indicated to be operated for heating at the momentThe heating capacity in the mode is low, and the indoor fan needs to be controlled to operate at a high-wind gear and/or the compressor needs to be controlled to operate at a high-frequency gear, so that the temperature of the coil of the indoor heat exchanger is rapidly increased.
And step S22, when the temperature of the coil pipe reaches the first temperature, controlling the indoor fan to operate at a low-wind gear and/or controlling the compressor to operate at a low-frequency gear.
In this embodiment, the temperature of the coil rises to reach a first temperature T1E.g. 30 c, indicating that the temperature is sufficient, the indoor fan may be controlled to operate in a low wind step and/or the compressor may be controlled to operate in a low frequency step.

In the third embodiment, referring to fig. 4, based on the second embodiment, the step S2 further includes:
and step S23, when the temperature of the coil pipe is higher than the second temperature, controlling the indoor fan to operate at a low-wind gear and/or controlling the compressor to operate at a low-frequency gear.
In this embodiment, when the air conditioning system starts to operate in the heating mode, if it is detected that the temperature T of the coil of the indoor heat exchanger is greater than the second temperature T2E.g., 20 c, when the indoor fan is directly controlled to operate at a low wind speed and/or the compressor is controlled to operate at a low frequency speed.

Therefore, the specific rotating speed of each gear of the indoor fan and the specific frequency of each gear of the compressor can be specifically adjusted in combination with the outdoor environment temperature.
