Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and in particular to a method, device, equipment, medium and air conditioner for starting an indoor unit of an air conditioner. Background Art

[0002] One-to-many air conditioners are a large branch of split air conditioners. It has multiple indoor units that can be used in multiple rooms, but shares one outdoor unit. There are two main types of one-to-many air conditioners on the market. The first type is an outdoor unit with several compressors. Each compressor is connected to the corresponding indoor unit. The number of indoor units is equal to the number of outdoor unit compressors. Each indoor unit is controlled separately. Starting an indoor unit will start a corresponding compressor. The second type is the central air conditioning system. The heating system provides the required heat for the air conditioning system to offset the indoor environment heating and cooling loads. Often, an extension is set in each room, and each extension corresponds to an air conditioner indoor unit. However, for the entire central air conditioner, there is often a situation where the compressor works, but one or more of the air conditioner indoor units do not work. The reason is that the user has set the ideal temperature in advance, and the central air conditioning system stops the operation of the air conditioner indoor unit after detecting that the indoor temperature has reached the ideal temperature.

[0003] Especially when the air conditioner is in heating mode, when the ambient temperature of a room reaches the temperature set by the remote control, the indoor unit in the current room stops supplying air, but a small amount of refrigerant will still pass through the stopped indoor unit system. At this time, since the ambient temperature sensor of the current room is located on the upper part or side of the evaporator, it is close to the evaporator, which will cause a large difference between the detected ambient temperature and the actual temperature in the room. Usually, the measured ambient temperature will be higher than the set temperature. However, in such a case, on the one hand, the actual ambient temperature in the room is lower than the set temperature, and on the other hand, because the set temperature in the room is at the temperature reached, the indoor unit cannot be restarted, which will seriously affect the user's comfort in heating mode.

[0004] At present, there is no technical solution that compares the ambient temperature and coil temperature at different times and takes corresponding measures when the indoor unit stops running, so as to make the room temperature closer to the user's needs. Specifically, there is no method, device, equipment, medium and air conditioner for starting the indoor unit of an air conditioner. Summary of the invention

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] It should be noted that in the description of the embodiments of the present invention, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "include one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. Unless otherwise clearly specified and defined, the terms "install", "connect" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0047] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0048] Figure 1 It is one of the flow diagrams of a method for starting an indoor unit of an air conditioner provided by the present invention, and the method for starting an indoor unit of an air conditioner comprises:

[0049] Obtaining a first coil temperature and a first ambient temperature at a first moment;

[0050] After a first preset time interval, obtaining a second coil temperature and a second ambient temperature at a second moment;

[0051] When the difference between the first coil temperature and the second coil temperature is less than the first preset temperature difference, and the difference between the first ambient temperature and the second ambient temperature is greater than the second preset temperature difference, starting the target indoor unit;

[0052] When the difference between the first coil temperature and the second coil temperature is greater than the first preset temperature difference, and the difference between the first ambient temperature and the second ambient temperature is greater than the third preset temperature difference, the target indoor unit is started.

[0053] In step S101, the air conditioner is in the initial state, and the indoor unit of the air conditioner is in operation. When the ambient temperature sensor arranged on the evaporator side detects that the current indoor ambient temperature has reached the temperature previously set by the user, the current indoor unit of the air conditioner will be shut down to save power and meet user needs. However, due to the location of the ambient temperature sensor and the occasional passage of fluid from other pipes, heat release is increased, so that the measured ambient temperature will be higher than the actual ambient temperature. Therefore, the current indoor unit of the air conditioner is stopped before the user's preset temperature is reached.

[0054] The present invention aims to eliminate such technical defects, so that if the temperature set by the user, that is, the current ambient temperature, does not reach the current set temperature, the air conditioner indoor unit will continue to be in operation. Therefore, the first moment in the present invention is aimed at any moment when the air conditioner indoor unit is in a stopped operating state. More specifically, the present invention will take a one-to-many air conditioner as the object of explanation. In a one-to-many air conditioning system, there is a compressor system and multiple air conditioners indoor units connected to the compressor system. Usually, one air conditioner indoor unit is set in one room to control the temperature of the current room. Therefore, when the air conditioners indoor units in other rooms are in operation, due to other structural reasons such as pipeline settings, some fluids will pass through the vicinity of the air conditioner indoor unit in the current room, resulting in a high temperature near the air conditioner indoor unit, which cannot truly reflect the actual temperature of the current indoor environment, that is, the operation of the air conditioners indoor units in other rooms will affect the operation of the air conditioners indoor units in the current room to a certain extent.

[0055] The first coil temperature is determined by an inner coil temperature sensor arranged near the inner coil of the air-conditioning indoor unit, and the first ambient temperature is determined by an ambient temperature sensor arranged near the evaporator of the air-conditioning indoor unit. Those skilled in the art understand that the setting position of the inner coil temperature sensor and the setting position of the ambient temperature sensor are the conventional design positions for setting the indoor unit sensor in the air-conditioning field.

[0056] In step S102, a second coil temperature and a second ambient temperature at a second moment are obtained at intervals of a first preset time period, and the first preset time period may be 1 minute, 3 minutes, 5 minutes, etc., that is, in one embodiment, the second coil temperature and the second ambient temperature are obtained every 3 minutes, and the second coil temperature is also determined by an inner coil temperature sensor arranged near the inner coil of the air-conditioning indoor unit, and the second ambient temperature is also determined by an ambient temperature sensor arranged near the evaporator of the air-conditioning indoor unit. The present invention provides a judgment inspiration for restarting the air-conditioning indoor unit by comparing the temperature difference between the first coil temperature and the second coil temperature and the temperature difference between the first ambient temperature and the second ambient temperature after a certain time interval.

[0057] In step S103, the first preset temperature difference may be 1°C, 3°C or 5°C, and the second preset temperature difference may be 1°C, 3°C or 5°C, that is, in a preferred embodiment, in step S103, a start condition for starting the target indoor unit is given, for example, when the difference between the first coil temperature and the second coil temperature is less than 3°C, and the difference between the first ambient temperature and the second ambient temperature is greater than 1°C, the target indoor unit is started. If the difference between the first coil temperature and the second coil temperature is less than the first preset temperature difference, and the difference between the first ambient temperature and the second ambient temperature is less than the second preset temperature difference, the current operating state of the air conditioner indoor unit is kept unchanged, and if the current air conditioner indoor unit is not in operation, the air conditioner indoor unit is kept in operation.

[0058] In step S104, another start condition for starting the target indoor unit is given, for example, when the difference between the first coil temperature and the second coil temperature is greater than 1°C, and the difference between the first ambient temperature and the second ambient temperature is greater than 3°C, the target indoor unit is started. If the difference between the first coil temperature and the second coil temperature is greater than the first preset temperature difference, and the difference between the first ambient temperature and the second ambient temperature is less than the second preset temperature difference, the current operating state of the air conditioner indoor unit is maintained unchanged, and if the current air conditioner indoor unit is in a non-operating state, the air conditioner indoor unit is maintained in a non-operating state.

[0059] Optionally, before obtaining the first coil temperature and the first ambient temperature at the first moment, the method includes:

[0060] When it is determined that the compressor is in the working state, determining a target indoor unit in the non-working state;

[0061] The compressor is used to cooperate with multiple indoor units to perform heating work;

[0062] Therefore, the target indoor unit is at least one of the multiple indoor units that stop working after the temperature exceeds the preset temperature.

[0063] Those skilled in the art will appreciate that the present invention aims to solve the technical problem that the indoor unit of the air conditioner is not in a working state, but the indoor ambient temperature cannot reach the user's preset temperature. Therefore, first, it is determined whether the compressor is in a working state. If the compressor is not in a working state, it is possible to directly determine whether to turn on the indoor unit of the air conditioner based on the ambient temperature. When it is determined that the compressor is in a working state, the target indoor unit of the air conditioner that was previously in a working state is screened out through manual determination or intelligent detection, and the target indoor unit of the air conditioner is automatically turned off after it is determined that the temperature is greater than the preset temperature.

[0064] The compressor is used to cooperate in performing heating work of multiple indoor units. The present invention is intended to be used in air-conditioning heating mode, so the target indoor unit can be one of the multiple indoor units that stop working after the temperature is greater than a preset temperature, or it can be multiple indoor units that stop working after the temperature is greater than a preset temperature.

[0065] Optionally, after determining the target indoor unit that is not in a working state, the method further includes:

[0066] After a second preset time period, a target indoor unit that is not in operation is determined until the compressor is in the not operating state.

[0067] Because the compressor is in a state of continuous operation when the air conditioner is heating, its associated air-conditioning indoor units will realize partial restart of the indoor units based on the control logic of the present invention. Some air-conditioning indoor units will stop working after reaching the temperature. In order to meet the set requirements of all users in the rooms managed by the air-conditioning indoor units currently covered by the compressor, a second preset time period may be intervals to determine the target indoor units that are not working until the compressor is not working. The second preset time period may be 5 minutes, 10 minutes, 30 minutes or even more, that is, the target indoor units that need to be detected and monitored are re-determined every period of time.

[0068] The present invention takes the indoor unit of the air conditioner in the shutdown state as the judgment object, continuously compares the coil temperature and the ambient temperature at continuous time intervals, and starts the target indoor unit when the preset conditions are met, thereby effectively solving the technical problem that the indoor unit of the air conditioner stops working after detecting that the ambient temperature reaches the target setting temperature, thereby failing to meet the user's set requirements. The present invention determines whether to start the target indoor unit by comparing the difference between the first coil temperature and the second coil temperature and the difference between the first ambient temperature and the second ambient temperature, so that the temperature in the room is closer to the user's needs, thereby improving the user's satisfaction and the user's comfort in using the air conditioner.

[0069] Figure 2 is a flow chart of determining the third preset temperature difference provided by the present invention, after obtaining the second coil temperature and the second ambient temperature at the second moment, further comprising:

[0070] Determine a third preset temperature difference according to the second preset temperature difference and the correlation coefficient;

[0071] The third preset temperature difference is greater than the second preset temperature difference.

[0072] In such an embodiment, as an implementation method, the product of the second preset temperature difference and the correlation coefficient, plus the second preset temperature difference, is the third preset temperature difference; as another implementation method, the product of the second preset temperature difference and the correlation coefficient is the third preset temperature difference.

[0073] Optionally, determining the third preset temperature difference according to the second preset temperature difference and the correlation coefficient includes:

[0074] When the difference between the first coil temperature and the second coil temperature is a negative number, determining a third preset temperature difference based on the second preset temperature difference and the first correlation coefficient;

[0075] When the difference between the first coil temperature and the second coil temperature is a positive number, determining a third preset temperature difference based on the second preset temperature difference and the second correlation coefficient;

[0076] The correlation coefficient includes a first correlation coefficient and a second correlation coefficient;

[0077] The first correlation coefficient is smaller than the second correlation coefficient.

[0078] In step S201, that is, the first coil temperature is less than the second coil temperature, and the correlation coefficient set at this time is designated as the first correlation coefficient. For example, the first correlation coefficient is 0.5, that is, the product of the second preset temperature difference and the correlation coefficient, plus the second preset temperature difference, is the third preset temperature difference. When the second preset temperature difference is 2°C, the third preset temperature difference is 3°C.

[0079] In step S202, that is, the first coil temperature is greater than the second coil temperature, and the correlation coefficient set at this time is designated as the second correlation coefficient. For example, the second correlation coefficient is 1.5, that is, the product of the second preset temperature difference and the correlation coefficient, plus the second preset temperature difference, is the third preset temperature difference. When the second preset temperature difference is 2°C, the third preset temperature difference is 5°C.

[0080] The first correlation coefficient is smaller than the second correlation coefficient, and in other embodiments, the relationship between the first correlation coefficient and the second correlation coefficient can be further limited, for example, the first correlation coefficient is set to a value less than 1, and the second correlation coefficient is set to a value greater than 1.

[0081] Figure 3This is a second flow chart of a method for starting an indoor unit of an air conditioner provided by the present invention, which includes, after obtaining a second coil temperature and a second ambient temperature at a second moment after a first preset time interval:

[0082] At intervals of a first preset time, the coil temperature and the ambient temperature at each moment are obtained;

[0083] Compare the temperature difference between the coil temperature at each moment and the coil temperature at the previous moment, as well as the temperature difference between the ambient temperature at each moment and the ambient temperature at the previous moment, until the target indoor unit is started.

[0084] In step S301, the present invention provides a technical solution for continuously monitoring the target indoor unit, wherein the first preset time length can be 1 minute, 3 minutes, 5 minutes, etc., and the coil temperature and the ambient temperature are obtained once at a certain interval to obtain the coil temperature and the ambient temperature obtained each time.

[0085] In step S302, the temperature difference between the coil temperature at each moment and the coil temperature at the previous moment, as well as the temperature difference between the ambient temperature at each moment and the ambient temperature at the previous moment are compared, and they are analyzed and compared through steps S101 to S104 to determine whether to turn on the target indoor unit, or until the user turns off the compressor.

[0090] The present invention takes the indoor unit of the air conditioner in the shutdown state as the judgment object, continuously compares the coil temperature and the ambient temperature at continuous time intervals, and starts the target indoor unit when the preset conditions are met, thereby effectively solving the technical problem that the indoor unit of the air conditioner stops working after detecting that the ambient temperature reaches the target setting temperature, thereby failing to meet the user's set requirements.
