Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

When the air conditioner operates in certain environments (such as low temperature environments), refrigerant may be dissolved in the compressor lubricating oil. During the start-up phase of the air conditioner, if the air volume of the indoor fan is relatively large, especially when the indoor fan includes several fan units and multiple fan units are running at the same time, the exhaust pressure of the air-conditioning system will be greatly reduced, which will cause the compressor lubricating oil. The solubility of the refrigerant in the medium is reduced, so that the refrigerant evaporates and foams rapidly, and a large amount of refrigerant and lubricating oil are taken away, which leads to the risk of oil shortage of the compressor and affects the reliability of the operation of the compressor.

In view of this, embodiments of the present invention provide the following air conditioning control methods to solve the above problems.

As shown in Figure 1, an air conditioning control method includes the following steps:

Step 101: Determine the first capacity increment of the indoor fan according to the rate of change of the exhaust pressure.

Step 102: Control the indoor fan to start at a first capacity, where the first capacity is less than or equal to the first capacity increment, under the condition that the indoor fan has the start-up condition.

The air conditioning control method of the embodiment of the present invention is applied to an air conditioning system. When the air-conditioning system receives an instruction to turn on the outdoor unit, the air-conditioning system can control the compressor to start. After the compressor is started, the exhaust pressure of the air-conditioning system gradually increases.

In step 101, the air conditioning system may determine the first capacity increment of the indoor fan according to the rate of change of the exhaust pressure.

The first capacity increment can be understood as the newly added capacity of the indoor fan. That is to say, under the condition that the newly added capacity of the indoor fan does not exceed the first capacity increment, the operation of the indoor fan will not cause a large fluctuation in the exhaust pressure, and the exhaust pressure can be maintained within a relatively stable variation range. . The first capacity increment may be greater than or equal to the target operating capacity of the indoor fan, or may be smaller than the target operating capacity of the indoor fan, where the target operating capacity of the indoor fan refers to the maximum capacity that the indoor fan needs to run under the current operating conditions .

The corresponding relationship between the rate of change of the exhaust pressure and the capacity increment of the indoor fan can be obtained through experiments in advance, or can be obtained through self-learning of the air conditioning system, which is not specifically described in the embodiment of the present invention.

Under different ambient temperatures, the corresponding relationship between the discharge pressure change rate and the capacity increment of the indoor fan may be different. Generally, the lower the ambient temperature is, the more refrigerant is dissolved in the compressor lubricating oil, and the higher the ambient temperature is, the less refrigerant is dissolved in the compressor lubricating oil. Therefore, the lower the ambient temperature is, the smaller the first capacity increment corresponding to the same exhaust pressure change rate may be; the higher the ambient temperature, the larger the first capacity increment corresponding to the same exhaust pressure change rate may be.

In the embodiment of the present invention, the air conditioning system can monitor the magnitude of the exhaust pressure corresponding to each monitoring time point, and the air conditioning system can also monitor the change value of the exhaust pressure corresponding to each time period.

In this way, the air conditioning system can obtain the rate of change of the exhaust pressure with time, that is, the rate of change of the exhaust pressure, by monitoring the relevant data of the exhaust pressure and processing the relevant data of the exhaust pressure.

In the embodiment of the present invention, in addition to determining the capacity increment according to the exhaust pressure change rate, the capacity ratio increment may also be determined according to the exhaust pressure change rate.

In step 102, if the indoor fan meets the starting conditions, the air conditioning system may control the indoor fan to start at the first capacity. Wherein, the first capacity is less than or equal to the first capacity increment.

The above-mentioned first capacity is less than or equal to the target operating capacity of the indoor fan. If the first capacity increment is greater than or equal to the target operating capacity of the indoor fan, the above-mentioned first capacity may be the target operating capacity of the indoor fan. That is, when the first capacity increment is greater than or equal to the target operation capacity of the indoor fan, the indoor fan may be controlled to be turned on at the target operation capacity. If the first capacity increment is smaller than the target operation capacity of the indoor fan, the above-mentioned first capacity is smaller than the target operation capacity of the indoor fan.

When the air conditioning system is under different working conditions, the starting conditions of the indoor fan may be different. When the air conditioning system is under the same working condition, the starting conditions of the indoor fan may also include one or more. The starting conditions of the indoor fan can be related to parameters such as exhaust pressure, air pipe temperature, liquid pipe temperature and so on.

For example, in the heating condition, after the heating of the air-conditioning system is started, in order to avoid the user's discomfort caused by the low outlet air temperature of the indoor fan, the air-conditioning system can adjust the air-conditioning system according to the exhaust pressure, indoor unit air pipe temperature or indoor unit fluid temperature. Pipe temperature and other parameters to determine whether the indoor fan has the starting conditions.

Since the air pipe temperature and liquid pipe temperature of the indoor unit can better reflect the air outlet temperature of the indoor fan, the air pipe temperature threshold or liquid pipe temperature threshold of the indoor unit can be preset. If the indoor unit air pipe temperature or liquid pipe temperature When the preset threshold is reached, it can be determined that the indoor fan has the starting conditions.

In some embodiments, the air conditioning control method further includes:

Under the heating condition, if the indoor unit exits the anti-cold air mode, it is determined that the indoor fan has the starting condition.

Specifically, if the air pipe temperature or the liquid pipe temperature of the indoor unit is greater than or equal to the third threshold, it is determined that the indoor fan exits the anti-cold air mode.

In the embodiment of the present invention, by monitoring the exhaust pressure of the air conditioning system, and determining the capacity of the fan that can be increased according to the rate of change of the exhaust pressure, the capacity control can be performed on the start or operation of the fan, thereby reducing the effect of fan operation on the exhaust air. effects of stress.

Generally speaking, the solubility of refrigerant in lubricating oil is related to the exhaust pressure. The greater the exhaust pressure, the greater the solubility of refrigerant in lubricating oil; The smaller it is; the greater the fluctuation of the exhaust pressure, the greater the fluctuation of the solubility of the refrigerant in the lubricating oil. Therefore, through the embodiments of the present invention, the fluctuation range of the exhaust pressure can be controlled, so that the solubility of the refrigerant in the lubricating oil can be kept stable, and the phenomenon of rapid evaporation and foaming of the refrigerant can be effectively avoided or alleviated, thereby ensuring the lubricating oil. The oil level is stable, which improves the reliability of the compressor operation.

Taking the heating condition as an example, the heat exchanger of the indoor unit is in the condenser state, and the heat of the condenser is discharged through the action of the indoor fan. Under different air volume (or operating capacity), the state of the condenser is different. Through optimized control, the range of air volume change can be adjusted, and the capacity of the condenser can be adjusted to avoid rapid fluctuation of exhaust pressure, thereby avoiding refrigerant flash. As the discharge temperature increases, the refrigerant can be discharged slowly, and the oil level of the compressor can be kept stable.

In the initial stage of compressor startup, the discharge pressure is small, and the rate of change of the discharge pressure is generally fast, but with the increase of the compressor start-up time, the discharge pressure gradually increases, and the rate of change of the discharge pressure becomes more and more more stable. Generally, the more stable the exhaust pressure change rate is, the more reasonable the determined first capacity increment is.

In view of this, the step of determining the capacity increment of the indoor fan according to the change rate of the exhaust pressure includes:

When the exhaust pressure is greater than or equal to a first threshold value, a first capacity increment of the indoor fan is determined according to the exhaust pressure change rate.

In addition, when the exhaust pressure is greater than or equal to the first threshold, the indoor fan may already have the activation condition. Therefore, under the condition that the exhaust pressure is greater than or equal to the first threshold value, the first capacity increment determined according to the rate of change of the exhaust pressure can be currently used to control the start of the fan, so that the determination time of the first capacity increment can be avoided from being different from There is a large time interval between the starting times of the indoor fans, which improves the accuracy of air conditioning control.

After the indoor fan is started, if the current running capacity of the indoor fan is less than the target running capacity of the indoor fan, it is necessary to continue to increase the running capacity of the indoor fan after a period of time, so that the running capacity of the indoor fan is gradually increased to the target running capacity. With the continuous operation of the compressor, the exhaust pressure of the air-conditioning system will tend to increase under the condition that the operating capacity of the indoor fan does not change. Therefore, when the exhaust pressure reaches a certain value, the following indoor fan control strategy can be implemented.

That is, after the step of controlling the indoor fan to start at the first capacity, the method further includes:

In the case that the exhaust pressure is greater than or equal to the second threshold value, determining the second capacity increment of the indoor fan according to the current exhaust pressure change rate;

The indoor fan is controlled to increase from a current capacity to a second capacity, where the difference between the second capacity and the current capacity is less than or equal to the second capacity increment.

Wherein, the second threshold may be equal to the first threshold, or may not be equal to the first threshold. The second capacity is less than or equal to the target operating capacity.

In the case that the operating capacity of the indoor fan does not reach the target operating capacity, the air-conditioning system may repeat the above process until the operating capacity of the indoor fan reaches the target operating capacity.

In this embodiment of the present invention, the indoor fan may include a single fan unit, or may include several fan units. In the following, the execution modes of the air conditioning system will be described in detail with respect to the two embodiments respectively.

When the fan unit is a DC motor, the air conditioning system can start the fan unit at the lowest speed, and after the fan unit runs for a certain period of time, gradually increase the fan speed to the target speed; when the fan unit is an AC motor, the air conditioning system can start at the lowest gear.

According to the sequence in which the fan unit sends the start-up commands, the start-up sequence of the fan unit is executed, which can meet the comfort requirements of the user.

The start-up sequence of the fan unit can be the order of the start-up capacity of the fan unit that issued the start-up command. For example, the start-up sequence of the fan unit is the order of the start-up capacity of the fan unit from large to small, or the start-up sequence of the fan unit is the start-up sequence of the fan unit. Capacity from smallest to largest.

The fan unit of the indoor fan is preset with a priority order, and the air conditioning system can start the fan unit according to the preset priority order.

The fan unit of the indoor fan is equipped with a fan unit that detects or receives human activity signals, and the air conditioning system can preferentially start the fan unit with the human activity information to meet the user's comfort needs.
