Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the air conditioner is operated in some environments (e.g., low temperature environment), the compressor lubricant oil may have a refrigerant dissolved therein. At the air conditioner starting stage, if the operating air volume of the indoor fan is large, especially under the condition that the indoor fan comprises a plurality of fan units and a plurality of fan units operate simultaneously, the exhaust pressure of the air conditioning system can be greatly reduced, so that the solubility of the refrigerant in the lubricating oil of the compressor is reduced, the refrigerant is rapidly evaporated and foamed, a large amount of refrigerant and lubricating oil are taken away, and the compressor is in risk of oil shortage and the reliability of the operation of the compressor is influenced.
In view of the above, embodiments of the present invention provide the following air conditioner control method to solve the above problems.
As shown in fig. 1, an air conditioner control method includes the steps of:
step 101: and determining a first capacity increment of the indoor fan according to the exhaust pressure change rate.
Step 102: and under the condition that the indoor fan has a starting condition, controlling the indoor fan to start at a first capacity, wherein the first capacity is smaller than or equal to the first capacity increment.
The air conditioner control method is applied to an air conditioner system. When the air conditioning system receives an outdoor unit opening instruction, the air conditioning system can control the compressor to start, and after the compressor starts, the exhaust pressure of the air conditioning system is gradually increased.
In step 101, the air conditioning system may determine a first capacity increment of the indoor fan according to the discharge pressure change rate.
The first capacity increment can be understood as the capacity that the indoor fan can newly add. 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 does not cause the exhaust pressure to fluctuate greatly, and the exhaust pressure can be maintained in a relatively stable variation range. The first capacity increment may be greater than or equal to a target operation capacity of the indoor fan, or may be smaller than the target operation capacity of the indoor fan, where the target operation capacity of the indoor fan refers to a maximum capacity of the indoor fan required to operate under a current working condition.
The corresponding relationship between the exhaust pressure change rate and the capacity increment of the indoor fan can be obtained in advance through experiments or can be obtained through self-learning of the air conditioning system, and the embodiment of the invention does not specifically describe the corresponding relationship.
Under different environmental 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, the more refrigerant is dissolved in the compressor lubricant, and the higher the ambient temperature, the less refrigerant is dissolved in the compressor lubricant. Therefore, the lower the ambient temperature, the smaller the first capacity increment corresponding to the same rate of change of the exhaust pressure may be; the higher the ambient temperature, the greater the first capacity increment for the same rate of change of exhaust pressure may be.
In the embodiment of the invention, the air conditioning system can monitor the exhaust pressure corresponding to each monitoring time point, and the air conditioning system can also monitor the exhaust pressure variation value corresponding to each time period.
In this way, the air conditioning system can obtain the time-dependent change rate of the exhaust pressure, namely the change rate of the exhaust pressure, by monitoring the related data of the exhaust pressure and processing the related data of the exhaust pressure.
In the embodiment of the invention, in addition to determining the capacity increment according to the exhaust pressure change rate, the capacity ratio increment can also be determined according to the exhaust pressure change rate.
In step 102, if the indoor fan has the start condition, the air conditioning system may control the indoor fan to start at a first capacity. Wherein the first capacity is less than or equal to a first capacity increment.
The first capacity is less than or equal to a target operation capacity of the indoor fan. If the first capacity increment is greater than or equal to the target operation capacity of the indoor fan, the first capacity may be the target operation 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. And if the first capacity increment is smaller than the target operation capacity of the indoor fan, the first capacity is smaller than the target operation capacity of the indoor fan.
When the air conditioning system is in different working conditions, the starting conditions of the indoor fans may be different. The starting condition of the indoor fan can also comprise one or more conditions when the air conditioning system is in the same working condition. The start-up conditions of the indoor fan may be related to parameters such as exhaust pressure, gas pipe temperature, liquid pipe temperature, etc.
For example, in a heating condition, after the air conditioning system is started to heat, in order to avoid the problem that the outlet air temperature of the indoor fan is too low and causes discomfort to a user, the air conditioning system may determine whether the indoor fan has a starting condition according to parameters such as the exhaust pressure, the temperature of the indoor unit air pipe, or the temperature of the indoor unit liquid pipe.
The air pipe temperature and the liquid pipe temperature of the indoor unit can well reflect the air outlet temperature of the indoor fan, so that the air pipe temperature threshold or the liquid pipe temperature threshold of the indoor unit can be preset, and if the air pipe temperature or the liquid pipe temperature of the indoor unit reaches the preset threshold, the indoor fan can be judged to have the starting condition.
In some embodiments, the air conditioner control method further includes:
and under the heating condition, if the indoor unit exits the cold air prevention mode, judging 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 a third threshold value, it is determined that the indoor fan exits the cold air prevention mode.
In the embodiment of the invention, the discharge pressure of the air conditioning system is monitored, and the increasable fan capacity is determined according to the discharge pressure change rate, so that the capacity control can be carried out on the starting or the operation of the fan, and the influence of the fan operation on the discharge pressure can be reduced.
Generally, the solubility of the refrigerant in the lubricating oil is related to the discharge pressure, the greater the solubility of the refrigerant in the lubricating oil; the smaller the discharge pressure, the smaller the solubility of the refrigerant in the lubricating oil; the greater the magnitude of the fluctuation in discharge pressure, the greater the fluctuation in solubility of the refrigerant in the lubricating oil. Therefore, the embodiment of the invention can control the fluctuation range of the discharge pressure, thereby keeping the solubility of the refrigerant in the lubricating oil stable, effectively avoiding or relieving the rapid evaporation foaming phenomenon of the refrigerant, ensuring the oil level stability of the lubricating oil and improving the operation reliability of the compressor.
Taking a heating working condition as an example, the heat exchanger of the indoor unit is in a condenser state, and the heat of the condenser is discharged through the action of the indoor fan. Under different air volumes (or operation capacities), the states of the condensers are different, the air volume change amplitude is adjusted through control after optimization, the capacity of the condensers is adjusted, rapid fluctuation of exhaust pressure is avoided, and further flash of refrigerants is avoided. As the discharge temperature increases, the refrigerant can be slowly discharged and the compressor oil level can be kept stable.
In the initial stage of the starting of the compressor, the exhaust pressure is smaller and the change rate of the exhaust pressure is generally faster, and as the starting time of the compressor is increased, the exhaust pressure is gradually increased and the change rate of the exhaust pressure tends to be more and more stable. Generally, the more stable the rate of change of exhaust pressure, the more reasonable the first capacity increment is determined.
In view of this, the step of determining the capacity increment of the indoor fan according to the exhaust pressure change rate includes:
and under the condition that the exhaust pressure is greater than or equal to a first threshold value, determining a first capacity increment of the indoor fan according to the exhaust pressure change rate.
Further, the indoor fan may already be provided with a start condition when the discharge pressure is greater than or equal to the first threshold value. 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 exhaust pressure change rate can be currently used for controlling the fan to start, so that a larger time interval between the determination time of the first capacity increment and the starting time of the indoor fan can be avoided, and the air conditioning control accuracy is improved.
After the indoor fan is started, if the current operating capacity of the indoor fan is smaller than the target operating capacity of the indoor fan, the operating capacity of the indoor fan needs to be continuously increased after a period of time, so that the operating capacity of the indoor fan is gradually increased to the target operating capacity. As the compressor continues to operate, the discharge pressure of the air conditioning system tends to increase when the operating capacity of the indoor fan is not changed. Therefore, when the discharge pressure reaches a certain value, the following control strategy of the indoor fan may be performed.
That is, after the step of controlling the indoor fan to be activated at the first capacity, the method further includes:
under the condition that the exhaust pressure is greater than or equal to a second threshold value, determining a second capacity increment of the indoor fan according to the current exhaust pressure change rate;
and controlling the indoor fan to be increased from the current capacity to a second capacity, wherein the difference value between the second capacity and the current capacity is smaller than or equal to the second capacity increment.
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.
Under the condition that the operation capacity of the indoor fan does not reach the target operation capacity, the air conditioning system can repeatedly execute the process until the operation capacity of the indoor fan reaches the target operation capacity.
In the embodiment of the invention, the indoor fan can comprise a single fan unit or a plurality of fan units. In the following, two embodiments are specifically described for the respective execution modes of the air conditioning system.
As an embodiment, the indoor fan includes a fan unit;
the step of controlling the indoor fan to start at a first capacity under the condition that the indoor fan has a starting condition includes:
and under the condition that the indoor fan has a starting condition, controlling the fan unit to start at the lowest rotating speed, wherein the capacity corresponding to the lowest rotating speed is less than or equal to the first capacity increment.
When the fan unit is a direct current motor, the air conditioning system can start the fan unit at the lowest rotating speed, and gradually increase the rotating speed of the fan to the target rotating speed after the fan unit operates for a certain time; when the fan unit is an alternating current motor, the air conditioning system can start the fan unit at the lowest gear, and gradually increase the gear of the fan to the target gear after the fan unit operates for a certain time. The target rotating speed or the target gear of the fan corresponds to the target operation capacity of the fan.
As another embodiment, the indoor fan includes a plurality of fan units;
the step of controlling the indoor fan to start at a first capacity under the condition that the indoor fan has a starting condition includes:
under the condition that the indoor fan has starting conditions, determining a target fan unit to be started according to the starting information of the fan units;
controlling the target fan unit to start at a first capacity.
The starting information of the fan units can comprise at least one of the following information:
the starting sequence of the fan units;
a starting capacity of the plurality of fan units.
When the starting capacity of each fan unit of the indoor fan is smaller than or equal to the first capacity increment, the air conditioning system can start the fan units according to the starting sequence of the fan units; when the starting capacity of one or some fan units of the indoor fan is larger than the first capacity increment, the air conditioning system starts the fan units in the first capacity increment range according to the starting sequence of the fan units.
Wherein the starting sequence of the fan units can be determined according to one of the following:
the sequence of the starting instructions sent by the fan units;
the starting capacities of the fan units are sequenced;
the preset priority order of the fan units;
and human body activity signals corresponding to the fan units.
The starting sequence of the fan unit may be a sequence in which the air conditioning system receives a starting instruction sent by the fan unit. According to the sequence of the starting instructions sent by the fan units, the starting sequence of the fan units is executed, and the comfort requirement of a user can be met.
The starting sequence of the fan units may be a size sequence of starting capacities of the fan units which send the starting instructions, for example, the starting sequence of the fan units is a sequence of starting capacities of the fan units from large to small, or the starting sequence of the fan units is a sequence of starting capacities of the fan units from small to large.
The fan unit of the indoor fan is preset with a priority sequence, and the air conditioning system can start the fan unit according to the preset priority sequence.
The fan unit of the indoor fan is provided with a fan unit which detects or receives human activity signals, and the air conditioning system can preferentially start the fan unit with human activity information so as to meet the comfort requirement of a user.
In some embodiments, after the step of controlling the target fan unit to start at the first capacity, the method further comprises:
and under the condition that the time after the indoor fan has the starting condition is more than or equal to the preset time, if the fan units are not all started, controlling the un-started fan units to start.
This embodiment can meet the comfort requirements of the user.
The present invention is exemplified below by taking a complete heating flow as an example.
The air conditioning system controls the compressor to start under the condition of receiving a heating starting instruction of the outdoor unit or a starting instruction after defrosting.
The air conditioning system monitors the exhaust pressure, when the exhaust pressure is larger than a preset threshold value, the exhaust pressure change rate is calculated, and the operation capacity of the newly added indoor fan is determined according to the exhaust pressure change rate.
The air conditioning system judges whether the indoor fan exits the cold air prevention mode, and if so, sends a request opening instruction to the outdoor unit.
And after receiving the opening instruction sent by the indoor fan, the outdoor unit sends an opening permission instruction to the indoor fan according to the determined operation capacity of the newly added indoor fan and the sequence of sending the opening instruction by the indoor fan.
And after the indoor fan receives the opening permission instruction, the indoor fan is started.
After the indoor fan is started, the indoor fan can gradually adjust the rotating speed of the fan according to the air outlet temperature and the target rotating speed.
Wherein, a corresponding relation table of the exhaust pressure change rate and the newly added indoor fan operation capacity may be preset, as shown in table 1.
