With the continuous improvement of people's living standards, people's pursuit of material beauty is also getting higher and higher, and air conditioners have become a necessity in life. Heat pump air-conditioning units generally have an anti-high temperature control function, which is used to prevent the unit's exhaust pressure from being too high, the exhaust temperature being too high, and the compressor overload during the whole heating process, so as to ensure the reliable operation of the unit. Specifically, during the use of the air conditioner, when the indoor coil reaches the high temperature protection value, the outdoor fan of the air conditioner stops running, and when the temperature of the indoor coil drops to the corresponding value, the normal operation of the outdoor fan will resume.

Subject to the influence of existing technology, manufacturing and process factors, there is a temperature difference between the actual indoor coil temperature and the temperature detected by the temperature sensor. The size of the temperature difference is related to the change speed and change size of the actual indoor coil temperature. The faster and bigger the tube temperature changes, the greater the temperature difference value, and under different ambient temperature conditions, the indoor coil temperature change amount is not the same when the compressor does the same heating work. However, the prior art only sets a fixed high temperature protection value (such as 56°C), which cannot be changed under different operating states. For example, in the heating startup phase or the heating stable operation phase, the same temperature is used Threshold or a threshold related to the operation stage, this control method exists that when the indoor temperature is too high (such as indoor temperature > 28 ℃), 56 ℃ is still used as the protection value for high temperature protection, which leads to a decrease in the reliability of the unit and reduces the manufacturing process. in comfort.

Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example 1

As shown in FIG. 1 , the present invention discloses a control method for heating and high temperature protection. The control method is applied to an air conditioner, and the control method includes the following steps:

Obtain real-time detection of indoor ambient temperature A;

Determine the ambient temperature interval in which the indoor ambient temperature A is located, and obtain the high temperature protection temperature threshold C corresponding to the current ambient temperature interval;

Obtain the real-time detected indoor coil temperature B;

When the indoor coil temperature B reaches the high temperature protection temperature threshold C, the air conditioner is controlled to enter a preset high temperature protection mode.

In this embodiment, the temperature sensing package or the temperature sensor in the detection unit detects the indoor ambient temperature A in real time, and determines which ambient temperature interval the ambient ambient temperature is in, so as to obtain the preset high temperature protection temperature threshold C corresponding to the current temperature interval, The corresponding relationship between the indoor ambient temperature A, the ambient temperature interval T and the preset high temperature protection temperature threshold C corresponding to the ambient temperature interval can be obtained by looking up a table, and then according to the indoor coil temperature B detected at this time, it is determined whether B ≥C, if yes, then control the air conditioner to enter the preset high temperature protection mode, such as stopping the external fan, switching the fan gears of the internal and external fans, etc.

In the general air conditioning control program, the high temperature protection value of the unit is unchanged. Even if there are some in the prior art that set different high temperature protection thresholds in different heating stages (such as the heating start-up stage and the heating stable operation stage), the high temperature protection threshold is also limited by the set heating stage, and will not Adjusts according to changes in indoor temperature. In the present invention, when heating, the indoor ambient temperature is detected and divided into intervals, and then a corresponding high temperature temperature threshold C is set for each ambient temperature interval, so as to obtain a high temperature protection temperature threshold related to the indoor ambient temperature. C, the high temperature protection temperature threshold C is not static, and then the current indoor coil temperature B is obtained through detection and compared with the high temperature protection temperature threshold C related to the current indoor ambient temperature. If B≥C is satisfied, the high temperature protection operation is performed; Otherwise, no processing is performed.

By setting an anti-high temperature temperature threshold value C related to the ambient temperature, the present invention can make the air conditioner adopt the most suitable temperature threshold value under different ambient temperatures to protect and control the high temperature protection of the air conditioner, thereby solving the problem of the prior art. In the heating process, the same temperature threshold is used for high temperature control in different environments, which leads to problems such as high exhaust pressure and compressor overload during the heating start-up phase of the unit, so as to improve the reliability of the unit and the comfort of heating. sexual purpose.

As some examples of the present invention, the number of ambient temperature and temperature threshold settings is N, where N is a positive natural number, and N≧2, so that N+1 ambient temperature intervals T are formed.

With the control method for heating and high-temperature protection of the present invention, the more ambient temperature ranges are set, the more corresponding high-temperature temperature thresholds C are, and the more accurate the high-temperature protection control is. However, the more ambient temperature ranges are set, the more processing workload of the judgment module and the control module will be, which brings additional burden to the execution of the heating and high temperature protection control method of the present invention.

Preferably, three ambient temperature intervals T are set, respectively corresponding to two ambient temperature thresholds, the first ambient temperature threshold A ₁ and the second ambient temperature threshold A ₂ , and A ₁ <A ₂ .

Considering comprehensively, the number N set for the high temperature protection temperature threshold C is 2, and N can also be any positive integer from 3, 4, 5, 6, 7, and 8. By setting at least two ambient temperature thresholds A ₁ , A ₂ , thereby forming at least three ambient temperature intervals T ₁ , T ₂ , T ₃ , the ambient temperature T ₁ <A ₁ in the first ambient temperature interval, the ambient temperature A ₁ ≤ T ₂ ≤ A ₂ in the second ambient temperature interval, and the first ambient temperature interval T 1 <A 1 . The ambient temperature T ₃ >A ₂ in the three ambient temperature ranges. This setting can not only ensure the accuracy of high temperature protection control, ensure the reliability of the unit operation and the comfort during heating, but also reduce the workload of the control method and reduce the hardware cost.

Preferably, each environmental temperature interval is correspondingly provided with a high temperature protection temperature threshold C, and the high temperature protection temperature threshold C decreases as the temperature in the environmental temperature interval increases. That is, the higher the corresponding ambient temperature in the ambient temperature interval T is, the smaller the corresponding high temperature temperature threshold C is. For example, the ambient temperature T ₁ <A ₁ in the first ambient temperature interval, the corresponding high temperature temperature threshold is C ₁ ; the ambient temperature in the second ambient temperature interval A ₁ ≤ T ₂ ≤ A ₂ , the corresponding The high temperature protection temperature threshold is C ₂ , C ₁ >C ₂ ; the ambient temperature T ₃ >A ₂ in the third ambient temperature interval, the corresponding high temperature protection temperature threshold is C ₃ , C ₂ >C ₃ .

According to the research, the applicant found that when the ambient temperature is high, it is in a high temperature environment range. At this time, if the high temperature protection temperature threshold value C is set too small, the time for the unit to enter the high temperature protection protection is shortened, and it is easy to enter frequently. If the high temperature protection temperature threshold C is set too high, the time for the unit to enter the high temperature protection will be prolonged, which will easily reduce the reliability of the unit operation. In the present application, the temperature range with a higher ambient temperature corresponds to a lower temperature threshold C for high temperature protection, so that the unit can enter the high temperature protection protection for a longer time in a low temperature environment, and can quickly enter the high temperature protection protection in a high temperature environment. Mode, so that the unit can reasonably enter the high temperature protection mode under different ambient temperatures, which not only avoids frequent access protection, but also ensures the reliability of the unit operation, and further improves the comfort during heating.

The control method for heating protection against high temperature according to the present invention, specifically, the control method for protection against high temperature for heating detects the indoor ambient temperature A, the indoor coil temperature B, and sets different high temperature protection temperature thresholds. C. When the detected indoor ambient temperature is higher than a certain fixed value, such as higher than A ₂ , and the indoor coil temperature B reaches a certain fixed value, such as C ₃ , it will enter the high temperature protection under this load; when the detected indoor ambient temperature Below a certain fixed value, such as lower than A ₁ , and when the indoor coil temperature B reaches a certain fixed value, such as C ₁ , it will enter the high temperature protection under this load, through this control method to improve the reliability and reliability of the unit. Heating comfort.

Preferably, when the heating is turned on, the ambient temperature interval in which the ambient temperature is determined is detected and judged according to the temperature in the ambient temperature interval T from low to high.

Under normal operating conditions, the ambient temperature is generally low when the heating is turned on. The ambient temperature interval in which the ambient temperature is located is detected and judged according to the temperature in the ambient temperature interval T from low to high. This setting optimizes the judgment sequence and reduces the judgment steps. . In addition, when the heating and high-temperature protection control method of the present invention is running, the ambient temperature interval in which the ambient temperature is determined can also be detected and judged according to the temperature in the ambient temperature interval T in descending order. The scheme applies when the setting is at a low ambient temperature threshold.

The control method can be applied to the whole heating process of the air conditioner, including the heating startup process stage and the heating stabilization process stage.
