Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
An embodiment of the application provides an outdoor unit defrosting control method, and fig. 1 shows a flowchart of the outdoor unit defrosting control method in the embodiment of the application. Although the present application provides method operational steps or apparatus configurations as illustrated in the following examples or figures, more or fewer operational steps or modular units may be included in the methods or apparatus based on conventional or non-inventive efforts. In the case of steps or structures which do not logically have the necessary cause and effect relationship, the execution sequence of the steps or the module structure of the apparatus is not limited to the execution sequence or the module structure described in the embodiments and shown in the drawings of the present application. When the described methods or modular structures are applied in a practical device or end product, they can be executed sequentially or in parallel according to the embodiments or the methods or modular structures shown in the figures (for example, in the environment of parallel processors or multi-thread processing, or even in the environment of distributed processing).
Specifically, as shown in fig. 1, an outdoor unit defrosting control method provided in an embodiment of the present application may include the following steps:
step S101, when the outdoor unit needs defrosting, acquiring a load parameter of the outdoor unit.
And S102, determining the defrosting mode of the outdoor unit according to the load parameters.
And step S103, controlling the outdoor unit to defrost in a defrosting mode.
Specifically, the outdoor unit defrosting control method in this embodiment may be applied to a multi-split air conditioning system. The outdoor unit of the multi-split air conditioning system may include a plurality of outdoor units. Whether the outdoor unit meets the defrosting condition or not can be judged, and when the outdoor unit meets the defrosting condition, the outdoor unit is determined to be defrosted. For example, whether the defrosting condition is satisfied may be determined by detecting a defrosting temperature, and when the detected defrosting temperature is less than a preset defrosting temperature, it is determined that the defrosting condition is satisfied.
When it is determined that the outdoor unit needs defrosting, the load parameter of the outdoor unit can be acquired. The load parameter is used for representing the load degree of the outdoor unit, namely the capacity distribution of the outdoor unit when the air conditioner is started. A larger load parameter indicates a higher degree of load. For example, the number of the outdoor units in operation in the outdoor unit and the total number of the outdoor units included in the outdoor unit may be obtained, and the percentage of the number of the outdoor units in operation to the total number of the outdoor units is determined as the load parameter. The above-described manner of acquiring the load parameter of the outdoor unit is exemplary, and the present application is not limited thereto.
After the load parameter of the outdoor unit is acquired, a defrosting mode of the outdoor unit may be determined according to the load parameter, and the outdoor unit may be controlled to defrost in the determined defrosting mode.
In the above embodiment, the defrosting mode is determined according to the load parameter of the outdoor unit, and the defrosting mode can be intelligently selected, so that the unit can be ensured to continuously heat under the condition of low load of the outdoor unit, continuous indoor hot air supply is ensured, severe fluctuation of indoor environment temperature is avoided, and comfortable experience of users is improved.
In one embodiment, the obtaining the load parameter of the outdoor unit may include: acquiring the running capacity and the installed total capacity of the outdoor unit; the percentage of the operating capacity to the total installed capacity is calculated and determined as a load parameter.
Specifically, the load parameter of the outdoor unit may be determined according to the operation capacity and the installed total capacity of the outdoor unit. The operation capacity of the outdoor unit may refer to the sum of powers of the outdoor units of the modules that are turned on when the air conditioner is turned on, and may also be referred to as a total power allocation capability of the turn-on module. The installed total capacity of the outdoor unit may refer to a sum of powers of all outdoor units of the outdoor unit of the air conditioner. The percentage of outdoor operating capacity to total installed capacity may be determined as a load parameter. The degree of load of the outdoor unit can be effectively characterized by determining the percentage of the operation capacity to the total installed capacity as the load parameter.
In one embodiment, determining a defrosting mode of the outdoor unit according to the load parameter may include: determining whether the load parameter is smaller than a first preset threshold value; and under the condition that the load parameter is determined to be smaller than a first preset threshold value, determining that the defrosting mode of the outdoor unit is a first defrosting mode.
In the case where the load parameter is less than the first preset threshold, it may be determined that the load of the outdoor unit is low. Under the condition that the load of the outdoor unit is low, the outdoor unit modules of the outdoor unit are usually operated alternately. In this case, it may be determined that the defrosting mode of the outdoor unit is the first defrosting mode. And in the first defrosting mode, the outdoor units of the outdoor units can be defrosted in turn. The first defrosting mode may include a continuous heating defrosting mode and a natural defrosting mode, wherein in the continuous heating defrosting mode, the outdoor units of the outdoor units alternately perform heating defrosting. Under the natural defrosting mode, all the outdoor modules of the outdoor unit are stopped in turn to absorb heat in the outdoor environment for natural defrosting.
For example, the outdoor unit may include three modular outdoor units: the outdoor unit 1, the outdoor unit 2, and the outdoor unit 3, and the three outdoor unit modules are rotated every 3 hours. Under the condition of low load, the requirement can be met only by opening the outer machine 1 and the outer machine 2, and the outer machine 3 stops; and after 3 hours, the operation is switched to the external machine 2 and the external machine 3, the external machine 1 is stopped, and the operation is performed in a circulating mode. In this case, when the outdoor units need defrosting, the outdoor units may be turned to defrost in turn (heating defrosting in turn, or natural defrosting in turn). For example, the outdoor unit 1 may be controlled to enter defrosting, and the outdoor units 2 and 3 may maintain heating operation. After the defrosting of the outdoor unit 1 is finished, the outdoor unit 2 can be controlled to enter the defrosting mode, and the outdoor unit 1 and the outdoor unit 3 keep heating operation. After defrosting of the outdoor unit 2 is finished, the outdoor unit 3 can be controlled to enter defrosting, and the outdoor unit 1 and the outdoor unit 2 keep heating operation. After the defrosting of the outdoor unit 3 is finished, the outdoor unit can be controlled to perform normal heating operation, namely, the outdoor unit is alternately operated every 3 hours.
For another example, the outdoor unit may include four modular outdoor units: the outdoor unit 1, the outdoor unit 2, the outdoor unit 3, and the outdoor unit 4. Under the condition of lower load, the requirement can be met only by opening the two outer units. In this case, when the outdoor unit needs defrosting, the outdoor units may be alternately heated to defrost or naturally defrost. For example, the outdoor units 1 and 2 may be controlled to be defrosted, and the outdoor units 3 and 4 may be maintained in heating operation. After the defrosting of the outdoor unit 1 and the outdoor unit 2 is finished, the outdoor unit 3 and the outdoor unit 4 can be controlled to enter the defrosting mode, and the outdoor unit 1 and the outdoor unit 2 are heated to run. After the defrosting of the outdoor unit 3 and the outdoor unit 4 is finished, the outdoor unit can be controlled to perform normal heating operation.
The above embodiments are merely exemplary, and the present application is not limited thereto. In the above embodiment, under the condition that the load of the outdoor unit is low, the outdoor unit is controlled to alternately perform heating defrosting or natural defrosting, so that all the outdoor units can be prevented from entering defrosting when the starting load is relatively low, severe fluctuation of the indoor environment temperature can be avoided, and user experience is improved.
Further, in an embodiment, determining a defrosting mode of the outdoor unit according to the load parameter may further include: under the condition that the load parameter is not smaller than the first preset threshold value, determining that the defrosting mode of the outdoor unit is a second defrosting mode; and in the second defrosting mode, all the outdoor units of the outdoor units simultaneously perform heating and defrosting.
Specifically, when the load of the outdoor unit is high, if the outdoor unit of the outdoor unit is frosted by turns, the outdoor unit that is turned on and kept in the heating mode may not meet the indoor air supply temperature. Therefore, when the load of the outdoor unit is large, a normal defrosting mode (also referred to as a discontinuous heating defrosting mode) is entered, that is, all the outdoor units of the outdoor unit perform heating defrosting simultaneously.
Further, in an embodiment, in a case that it is determined that the load parameter is less than the first preset threshold, determining that the defrosting mode of the outdoor unit is the first defrosting mode may include: determining whether the load parameter is greater than a second preset threshold value, wherein the second preset threshold value is smaller than the first preset threshold value; and under the condition that the load parameter is determined to be larger than a second preset threshold value, determining that the defrosting mode of the outdoor unit is a continuous heating defrosting mode. Specifically, when it is determined that the load parameter of the outdoor unit is between the first preset threshold and the second preset threshold, the defrosting mode of the outdoor unit may be determined as a continuous heating defrosting mode, that is, the outdoor units of the outdoor units perform heating defrosting in turn.
Further, in an embodiment, in a case that it is determined that the load parameter is smaller than the first preset threshold, determining that the defrosting mode of the outdoor unit is the first defrosting mode, the method may further include: under the condition that the load parameter is not larger than the second preset threshold value, determining whether the outdoor temperature is larger than the preset temperature or not; and under the condition that the outdoor temperature is determined to be higher than the preset temperature, determining that the defrosting mode of the outdoor unit is a natural defrosting mode.
Specifically, when the load parameter of the outdoor unit is determined to be less than or equal to the second preset threshold, that is, the load of the outdoor unit is low, the frosting period of the outdoor unit is long, and the defrosting mode of the outdoor unit can be determined by combining the outdoor temperature. In case that the outdoor temperature is greater than the preset temperature, the defrosting mode of the outdoor unit may be determined as the natural defrosting mode. That is, the outdoor unit modules can be controlled to be stopped to absorb heat in the outdoor environment for natural defrosting.
In the above embodiment, when the load of the outdoor unit is low and the outdoor temperature is high, the outdoor unit controls each module unit of the outdoor unit to naturally defrost, so that the power consumption can be reduced on the premise of keeping the indoor continuous hot air supply.
Further, in an embodiment, in a case that it is determined that the load parameter is smaller than the first preset threshold, determining that the defrosting mode of the outdoor unit is the first defrosting mode, may further include: and under the condition that the outdoor temperature is not greater than the preset temperature, determining that the defrosting mode of the outdoor unit is a continuous heating defrosting mode. Specifically, under the condition that the load is low and the outdoor temperature is not high, the outdoor units are controlled to defrost in a continuous heating defrosting mode, namely, the outdoor units of the modules are controlled to alternately heat and defrost, so that the defrosting speed can be increased on the premise of continuously heating the indoor space.
Referring to fig. 2, a flowchart of an outdoor unit defrosting control method in an embodiment of the present application is shown. As shown in fig. 2, the control method may include the steps of:
step S201, starting up an air conditioner to run;
step S202, judging whether the outdoor unit meets defrosting conditions, if so, executing step S204, otherwise, executing step S203;
step S203, the air conditioner normally operates;
step S204, acquiring a load parameter of the outdoor unit, wherein the load parameter is the percentage of the total distribution capacity of the starting module in the total installed capacity of the modules of the outdoor unit when the air conditioner is started;
step S205, determining whether the load parameter is smaller than a first preset threshold, if so, performing step S207, otherwise, performing step S206, where, for example, the first preset threshold may be 70%, and in other embodiments, the first preset threshold may also take other values, for example, the first preset threshold may be 60% to 80%, for example, 60%, 65%, 75%, 80%, and the like;
step S206, determining that the defrosting mode of the outdoor unit is a discontinuous heating defrosting mode, namely, all the outdoor units of the outdoor unit simultaneously perform heating defrosting;
step S207, determining whether the load parameter of the outdoor unit is smaller than a second preset threshold, if so, performing step S208, otherwise, performing step S210, where, for example, the second preset threshold may be 25%, and in other embodiments, the second preset threshold may also take other values, for example, the second preset threshold may be 5% to 30%, for example, 5%, 10%, 20%, 30%, and the like;
step S208, determining whether the outdoor environment temperature is greater than a preset temperature, if so, performing step S209, otherwise, performing step S210, where, for example, the preset temperature may be 0 ℃, and in other embodiments, the preset temperature may also take other values, for example, the preset temperature may be 0 ℃ to 10 ℃, for example, 4 ℃, 8 ℃, 10 ℃, and the like;
step S209, determining that the defrosting mode of the outdoor unit is a natural defrosting mode, namely, all the outdoor units of the outdoor unit stop in turn to absorb the outdoor environment for natural defrosting;
step S210, determining that the defrosting mode of the outdoor unit is a continuous heating defrosting mode, that is, the outdoor units of the outdoor units perform heating defrosting in turn.
According to the outdoor unit defrosting control method in the embodiment, the defrosting mode is determined by combining the load parameters of the outdoor unit and the outdoor environment temperature, the defrosting mode can be intelligently selected, the outdoor units of all modules are controlled to defrost in turn under the condition of low outdoor unit load, continuous heating of the units can be guaranteed, continuous indoor hot air supply is guaranteed, severe fluctuation of the indoor environment temperature is avoided, and comfortable experience of users is improved. Meanwhile, under the condition that the load of the external unit is high, the external units of the modules are controlled to simultaneously heat and defrost, and the defrosting period can be shortened. Furthermore, under the conditions of low load and high outdoor environment temperature, the outdoor units of the modules are controlled to naturally defrost in turn, so that the power consumption can be reduced.
