In the prior art, when the air conditioner operates in the heating mode, the discharge pressure and the discharge temperature of a compressor are high due to overhigh ambient temperature. In order to prevent the exhaust pressure and the discharge temperature of the compressor from being too high in the heating mode, the air conditioner generally reduces the exhaust pressure and the exhaust temperature of the compressor by performing high-temperature protection on the air conditioner, so that the reliability of the air conditioner is ensured. At present, the temperature of the high-temperature-resistant inner pipe is not changed when the high-temperature-resistant inner pipe enters or exits in the existing high-temperature-resistant control method, and high-temperature-resistant failure can occur in some cases (higher than indoor and outdoor temperature or unit liquid shortage), so that high-temperature protection or high-pressure protection of exhaust gas can occur.
Disclosure of Invention
The invention solves the problem that the temperature of the inner pipe for preventing high temperature is constant when the inner pipe enters and exits in the existing high temperature prevention control method, and high temperature prevention failure can occur under some conditions (higher than indoor and outdoor temperature or liquid shortage of a unit), so that high-temperature protection or high-pressure protection for exhaust can occur.
In order to solve the above problems, the present invention provides an air conditioner control method, including:
in the air-conditioning operation heating mode;
judging whether the air conditioner has exhaust high-temperature protection or not and whether the air conditioner has exhaust high-pressure protection or not;
and acquiring the temperature of the inner coil, and controlling the air conditioner to perform high-temperature protection according to the temperature of the inner coil and the judgment results of the high-temperature protection and the high-pressure protection.
Therefore, in the heating mode, whether the air conditioner has exhaust high-temperature protection or exhaust high-pressure protection is judged, after the judgment result is confirmed, the entering of the high-temperature protection or the keeping of the high-temperature protection or the quitting of the high-temperature protection is controlled through the obtained temperature of the inner coil and different judgment results, and the unit is prevented from having exhaust high-temperature protection or exhaust high-pressure protection again.
Further, according to the inner coil temperature and the judgment results of the exhaust high temperature protection and the exhaust high pressure protection, the air conditioner is controlled to perform high temperature protection, and the method comprises the following steps:
when the air conditioner has the exhaust high-temperature protection or the exhaust high-pressure protection;
before the temperature of the inner coil is obtained, the air conditioner carries out shutdown protection, and the heating mode is continuously operated after the air conditioner is restarted.
Therefore, after the air conditioner is subjected to exhaust temperature protection or exhaust high-pressure protection and needs to be restarted, normal heating is continued, and then the temperature of entering heat preservation or keeping high temperature or exiting high temperature protection is controlled according to the temperature of the inner coil pipe of the air conditioner.
Further, according to the inner coil temperature and the judgment results of the exhaust high temperature protection and the exhaust high pressure protection, the air conditioner is controlled to perform high temperature protection, and the method comprises the following steps:
when the exhaust high-temperature protection and the exhaust high-pressure protection do not occur;
and if the temperature of the inner coil is greater than or equal to the first preset temperature of the inner coil, the air conditioner enters the high-temperature-prevention protection, and the outer fan stops running.
From this, when air conditioner exhaust high temperature protection and exhaust high pressure protection do not appear, when interior coil pipe temperature is greater than or equal to first preset interior coil pipe temperature, the air conditioner gets into prevents high temperature protection, and outer fan stall through the heat transfer effect that reduces outdoor heat exchanger to reduce the return air temperature and the exhaust temperature of compressor.
Further, according to the inner coil temperature and the judgment results of the exhaust high temperature protection and the exhaust high pressure protection, the air conditioner is controlled to perform high temperature protection, and the method further comprises the following steps:
when the exhaust high-temperature protection and the exhaust high-pressure protection do not occur;
and if the temperature of the inner coil is lower than the temperature of the second preset inner coil, the air conditioner exits the high-temperature protection, and the outer fan starts to operate.
Therefore, when the temperature of the inner coil is lower than the second preset temperature of the inner coil, the air conditioner can accurately quit the high-temperature protection, the outer fan starts to operate, and the air conditioner operates normally.
Further, according to the inner coil temperature and the judgment results of the exhaust high temperature protection and the exhaust high pressure protection, the air conditioner is controlled to perform high temperature protection, and the method further comprises the following steps:
when the air conditioner has the exhaust high-temperature protection or the exhaust high-pressure protection;
and if the temperature of the inner coil is greater than or equal to the temperature of a third preset inner coil, the air conditioner enters the high-temperature-prevention protection, and the outer fan stops running.
Therefore, when the air conditioner has the high-temperature exhaust protection or the high-pressure exhaust protection, the temperature of the inner coil is greater than or equal to the temperature of a third preset inner coil, after the air conditioner enters the high-temperature prevention protection, the outer fan stops running, and the return air temperature and the exhaust air temperature of the compressor are reduced by reducing the heat exchange effect of the outdoor heat exchanger.
Further, according to the inner coil temperature and the judgment results of the exhaust high temperature protection and the exhaust high pressure protection, the air conditioner is controlled to perform high temperature protection, and the method further comprises the following steps:
when the air conditioner has the exhaust high-temperature protection or the exhaust high-pressure protection;
and if the temperature of the inner coil is lower than the temperature of the fourth preset inner coil, the air conditioner exits the high-temperature protection, and the outer fan starts to operate.
From this, when interior coil pipe temperature is less than the fourth and predetermines interior coil pipe temperature, the air conditioner can accurately withdraw from and prevent high temperature protection, and outer fan begins the operation, and the air conditioner carries out normal operating.
Further, the first preset inner coil temperature is greater than the third preset inner coil temperature.
Therefore, when the air conditioner has high-temperature exhaust protection or high-pressure exhaust protection, the problem of entering high-temperature protection is reduced, and the air conditioner enters the high-temperature protection in advance, so that the load of the air conditioner in a heating mode is reduced, and the running reliability of the air conditioner is improved.

note that the temperature T of the exhaust gas is passedRow boardJudging the exhaust high temperature protection and the exhaust pressure PRow boardThe judgment of the exhaust high-pressure protection is performed, and only one of the embodiments of the exhaust high-temperature protection and the exhaust high-pressure protection is determined. In another embodiment of the present invention, the air conditioner performs specific control according to the result of determining whether the air conditioner has high-temperature exhaust protection and high-pressure exhaust protection in the heating mode, and the specific steps include:
s1, in the air-conditioning operation heating mode;
s2, judging whether the air conditioner has exhaust high temperature protection or not and whether the air conditioner has exhaust high pressure protection or not;
s3, continuously acquiring the temperature T of the inner coilInner part；
S4, according to the temperature T of the inner coilInner partAnd controlling the air conditioner to perform high-temperature protection by judging results of the high-temperature protection and the high-pressure protection.
Hereinafter, in the present embodiment, the passing exhaust temperature T will be specifically described in the air-conditioning heating modeRow boardJudging the exhaust high temperature protection and the exhaust pressure PRow boardA specific explanation is made for determining the exhaust high pressure protection embodiment. By the obtained exhaust temperature TRow boardAnd the exhaust pressure PRow boardJudging whether the air conditioner has high exhaust temperature protection and high exhaustAnd pressure protection, namely exhaust high-temperature protection or exhaust high-pressure protection shows that the high-temperature protection is invalid, and the control of the high-temperature protection is carried out through the acquired temperature of the inner coil pipe, so that the unit is prevented from exhaust high-temperature protection or exhaust high-pressure protection again.
Specifically, as shown in fig. 2 and 3, according to the exhaust temperature TRow boardJudging whether the air conditioner has exhaust high-temperature protection or not, comprising the following steps:
s021, exhaust temperature TRow boardGreater than a first predetermined exhaust temperature TP1And in time, the air conditioner has exhaust high-temperature protection and needs the unit to be shut down. First preset exhaust temperature TP1The range of (A) is as follows: 110-.
According to the exhaust pressure PRow boardJudging whether exhaust high-pressure protection occurs or not, comprising the following steps:
s022, when the exhaust pressure PRow boardGreater than a first predetermined pressure P1And when the pressure switch is turned off, the air conditioner has exhaust pressure protection. Wherein the first preset pressure P1The parameters of the pressure switch are determined when the pressure switch is selected. Thereby, the exhaust pressure PRow boardGreater than a first predetermined pressure P1When the pressure switch is switched off, the corresponding pressure switch pair is automatically switched off to prevent overlarge pressure, and after the pressure switch is switched off, the air conditioner performs exhaust pressure protection and unit shutdown protection.
Specifically, after the air conditioner has high-temperature exhaust protection or high-pressure exhaust protection, the air conditioner performs shutdown protection, and when the air conditioner is restarted, the heating mode is operated, and then the temperature of the inner coil pipe is continuously obtained. On the contrary, when the air conditioner does not have exhaust high-temperature protection and exhaust high-pressure protection, the temperature of the inner coil is obtained in real time. Therefore, after the air conditioner is subjected to exhaust temperature protection or exhaust high-pressure protection and needs to be restarted, normal heating is continuously carried out, and then the air conditioner is controlled to enter high-temperature-prevention protection or keep high-temperature-prevention protection or exit high-temperature-prevention protection according to the temperature of an inner coil pipe of the air conditioner.

Second predetermined exhaust temperature TP2The range of (A) is as follows: 90-105 deg.c, indicating that the exhaust temperature below this range is already below the critical value and the air conditioner can operate normally.
S0222, when the exhaust pressure P isRow boardLess than or equal to a second preset exhaust pressure P2And when the pressure switch is closed, the air conditioner exhaust pressure protection is recovered (namely, the exhaust pressure protection does not occur), and the unit is restarted. Wherein the second preset pressure P2The parameters of the pressure switch are determined when the pressure switch is selected.
The above is that in the air-conditioning heating mode, the temperature T is passed throughRow boardJudging the exhaust high temperature protection and the exhaust pressure PRow boardA specific explanation is made for determining the exhaust high pressure protection embodiment.
As follows, in this embodiment, the specific steps directly according to the specific implementation of the determination results of the exhaust high-temperature protection and the exhaust high-pressure protection are as follows:

s42, inner coil temperature TInner partLess than a second predetermined internal coil temperature T2When the air conditioner is not in operation, the air conditioner is not protected by high temperature, and the outer fan starts to operate.
When the air conditioner does not have high-temperature exhaust protection and high-pressure exhaust protection, and the temperature of the inner coil is greater than or equal to the temperature of the first preset inner coil, the air conditioner enters high-temperature prevention protection, the outer fan stops running, and the return air temperature and the exhaust air temperature of the compressor are reduced by reducing the heat exchange effect of the outdoor heat exchanger; when the temperature of the inner coil pipe is lower than the second preset temperature of the inner coil pipe, the air conditioner can accurately quit the high-temperature protection, the outer fan starts to operate, and the air conditioner operates normally.
Wherein the first preset inner coil temperature T1The value range is as follows: 53-57 ℃, and the temperature range is the saturation temperature of exhaust gas when the unit normally runs in overload heating and the temperature T of the inner coilInner partIn the range, the exhaust temperature and the exhaust pressure of the unit under normal conditions can be ensured, so that the compressor can operate reliably. Second preset inner coil temperature T2The value range is as follows: the temperature of the coil pipe is between 49 and 53 ℃, the temperature of the coil pipe in the range ensures that the unit can normally exit the high temperature protection, and the temperature T of the coil pipe in the second preset range2The high temperature can lead the unit to frequently enter and exit the high temperature protection, the noise and the frequent fluctuation of the temperature are brought, and the temperature T of the second preset inner coil pipe2The low temperature can lead to the unit to be in for a long time and prevent high temperature, outdoor heat exchanger frosting, and the compressor returns liquid, influences reliability and heating capacity.
Specifically, as shown in fig. 4, when the air conditioner is stopped due to high-temperature exhaust protection or high-pressure exhaust protection of the air conditioner, the air conditioner is restarted, a heating mode is operated, the temperature of the inner coil is continuously obtained, and the temperature of the inner coil is obtained according to the temperature T of the inner coilInner partAnd the judgment results of the exhaust high-temperature protection and the exhaust high-pressure protection control the air conditioner to perform high-temperature protection, and the method further comprises the following steps:
s43, inner coil temperature TInner partGreater than or equal to a third predetermined internal coil temperature T3When the air conditioner enters the high-temperature protection, the outer fan stops running;
s44, inner coil temperature TInner partLess than the fourth preset inner coil temperature T4When the air conditioner is not in operation, the air conditioner is not protected by high temperature, and the outer fan starts to operate.
Thus, when the temperature T of the inner coil isInner partGreater than or equal to a third predetermined internal coil temperature T3In time, after the air conditioner enters the high temperature protectionThe external fan stops running, and the return air temperature and the exhaust air temperature of the compressor are reduced by reducing the heat exchange effect of the outdoor heat exchanger; when the temperature T of the inner coil pipeInner partLess than the fourth preset inner coil temperature T4During the time, the air conditioner can accurately withdraw from and prevent high temperature protection, and outer fan begins the operation, and the air conditioner normally operates.
Optionally, a first predetermined inner coil temperature T1Greater than a third predetermined internal coil temperature T3Second preset inner coil temperature T2Greater than the fourth preset inner coil temperature T4. The aim is to adjust the temperature of the inner coil pipe entering and/or exiting the high-temperature protection when the air conditioner has high-temperature exhaust protection or high-pressure exhaust protection, and reduce the load of the unit.
Preferably, the first preset internal coil temperature T1-M < third preset internal coil temperature T3< first preset inner coil temperature T1Second preset inner coil temperature T2-N < fourth preset internal coil temperature T4< second preset internal coil temperature T2. The range of values for M is: 3-7 ℃; the range of values for N is: 3-7 ℃; preferred values are: 5 ℃; preferred values of N are: 5 ℃ is adopted. The temperature of the inner coil pipe in the range can accurately determine to enter or/and exit the high-temperature protection, and the accuracy of the high-temperature protection is further improved.
