[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described in detail below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0037] The operation principle of the air conditioner related to the embodiments of the present application is described in detail as follows:

[0038] As Figure 1As shown, the compressor compresses the refrigerant and delivers it through pipes to the condenser. The high-temperature, high-pressure gaseous refrigerant releases heat in the condenser, transforming into a medium-temperature, high-pressure liquid refrigerant. Then, the medium-temperature, high-pressure liquid refrigerant is depressurized through a capillary tube (throttling unit) to become a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant is then delivered to the evaporator, where it evaporates into a gas, absorbing a large amount of heat during the evaporation process. Finally, the low-temperature, low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner is cooling, the outdoor unit's heat exchanger acts as the condenser, and the indoor unit's heat exchanger acts as the evaporator; conversely, when the air conditioner is heating, the outdoor unit's heat exchanger acts as the evaporator, and the indoor unit's heat exchanger acts as the condenser.

[0039] The main difference between the heating mode and the rapid heating mode of an air conditioner lies in their heating speed and energy consumption.

[0040] Heating mode is a basic operating mode in an air conditioning system. It absorbs low-temperature indoor air through the indoor unit, heats it, and then blows the hot air out to raise the indoor temperature. Heating mode is usually a constant-temperature heating mode, which can stably raise the indoor temperature to the set temperature; at the same time, heating mode has lower energy consumption because it only needs to maintain a stable heating power.

[0041] Rapid heating mode refers to the quick heating function provided by the air conditioning system under special circumstances. It increases the heating power of the indoor unit to accelerate the rise in indoor temperature. Compared to normal heating mode, rapid heating mode heats up faster and can raise the indoor temperature to the required temperature in a short time; however, rapid heating mode also consumes more energy because it requires more energy to provide greater heating power. In short, normal heating mode is suitable for scenarios where temperature requirements are not high, while rapid heating mode is suitable for scenarios requiring rapid heating, but energy consumption will be correspondingly higher.

[0042] In view of the technical problems of high energy consumption and slow heating speed in the rapid heating mode of related technologies, the embodiments of this application provide a rapid heating method for air conditioners, which can quickly increase the indoor ambient temperature with low energy consumption through reasonable control strategies.

[0043] The rapid heating method for air conditioners provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0044] like Figure 2 As shown in the embodiment of this application, a method for rapid heating of an air conditioner is provided, which may include the following steps 201 and 202:

[0045] Step 201, receiving a target instruction of starting a fast heating function, and judging whether a target environment parameter meets a preset temperature condition.

[0046] The target environment parameter includes at least one of an indoor-outdoor environment temperature difference and an outdoor environment temperature.

[0047] Exemplarily, the target instruction is used to trigger the fast heating function of the air conditioner, and the target instruction can be sent to the air conditioner by a user through voice, a remote controller, a mobile terminal or the like, or can be triggered by the system according to an automatic process.

[0048] Exemplarily, after receiving the target instruction, the air conditioner needs to judge whether an environment parameter of a current environment meets an opening condition of the fast heating function provided in the embodiments of the present application, that is, whether the target environment parameter meets the preset temperature condition.

[0049] It should be noted that, since the fast heating method of the air conditioner provided in the embodiments of the present application is mainly to reduce the viscosity of the lubricating oil in the refrigerant circulation system, improve the circulation efficiency of the refrigerant and the lubricating oil in the low-temperature winter environment, and then improve the heat exchange efficiency, and finally realize fast heating. Therefore, before starting the fast heating mode provided in the embodiments of the present application, it is necessary to judge whether the environment parameter of the current environment meets the opening condition of the fast heating function provided in the embodiments of the present application.

[0050] It can be understood that the viscosity of the lubricating oil is inversely proportional to the temperature, and the lower the temperature, the higher the viscosity of the lubricating oil. Therefore, when the outdoor environment temperature is low or the indoor-outdoor environment temperature difference is large, the viscosity of the lubricating oil in the outdoor heat exchanger pipeline is very high, which greatly affects the circulation efficiency of the refrigerant and the lubricating oil. Therefore, when it is judged that the viscosity of the lubricating oil in the outdoor heat exchanger pipeline is high, the temperature of the lubricating oil in the outdoor heat exchanger pipeline needs to be increased by delivering heat to the outdoor heat exchanger, so as to reduce the viscosity of the lubricating oil, speed up the oil return speed of the compressor, and shorten the oil return time, so as to heat faster.

[0051] It should be noted that the above-mentioned lubricating oil is the lubricating oil in the compressor, which enters the circulation system of the refrigerant when the air conditioner is running. When heating in a low-temperature environment, the viscosity of the lubricating oil in the outdoor heat exchanger increases, the return flow speed is slow, and the operation efficiency of the compressor and the circulation efficiency of the refrigerant are affected.

[0052] Specifically, the step 201 of judging whether the target environment parameter meets the preset temperature condition can include the following steps 201a1 and 201a2:

[0053] Step 201a1, acquiring the indoor environment temperature and the outdoor environment temperature, and calculating the indoor-outdoor environment temperature difference based on the indoor environment temperature and the outdoor environment temperature.

[0054] Step 201a2, determining that the target environment parameter meets the preset temperature condition in a case where the indoor-outdoor environment temperature difference is greater than a first preset threshold, and / or the outdoor environment temperature is less than a second preset threshold.

[0055] For example, as shown in FIG. 1, after the air conditioner is started, if the air conditioner receives a target instruction of starting the fast heating function, the air conditioner can acquire the indoor environment temperature and the outdoor environment temperature T0 through a temperature sensor, and calculate the indoor-outdoor environment temperature difference T1. In a case where T0 < 5℃ and / or T1 > 10℃, the fast heating function is started, otherwise, the air conditioner does not start the fast heating function. Figure 3 Step 202, controlling the air conditioner to execute a fast heating control strategy in a case where the target environment parameter meets the preset temperature condition.

[0056] The fast heating control strategy is used to reduce the viscosity of the lubricating oil in the refrigerant circulation system and increase the temperature of the coil of the indoor unit by changing the working mode.

[0057] For example, in the embodiment of the present application, in order to realize the rapid increase of the indoor environment temperature, after the air conditioner starts the fast heating function, the working mode needs to be switched to the cooling mode first, so that the high-temperature refrigerant can enter the heat exchanger of the outdoor unit, increase the temperature of the lubricating oil in the heat exchanger of the outdoor unit, and reduce the viscosity of the lubricating oil.

[0058] For example, after the viscosity of the lubricating oil in the outdoor heat exchanger is reduced, the working mode of the air conditioner is switched to the heating mode again to increase the temperature of the coil of the indoor unit. Since the circulation efficiency of the refrigerant and the lubricating oil is increased, the increase speed of the temperature of the coil of the indoor unit is obviously higher than that in the normal heating mode, so that the fast heating of the indoor environment can be realized.

[0059] It should be noted that, based on the operation principle of the air conditioner as shown in FIG. 1, when the air conditioner operates in the cooling mode, the indoor heat exchanger is an evaporator, and the refrigerant absorbs the heat of the indoor environment in the heat exchange process, which causes a low-temperature area near the indoor heat exchanger. At this time, the air conditioner closes the fan of the indoor unit to avoid affecting the user.

[0060] Figure 1 For example, if the target environment parameter does not meet the preset temperature condition, the fast heating mode can not be executed.

[0061] For example, if the target environment parameter does not meet the preset temperature condition, the fast heating mode can not be executed. ​

[0062] Exemplarily, after the step 201, the air conditioner rapid heating method provided by the embodiment of the present application can further include the following step 203:

[0063] The step 203 comprises: in the case that the target environment parameter does not satisfy the preset temperature condition, keeping the current operation mode of the air conditioner unchanged.

[0064] Specifically, the step 202 can include the following step 202a:

[0065] The step 202a comprises: before the air conditioner operates according to the first operation parameter corresponding to the heating mode, controlling the air conditioner to operate in the refrigeration mode and operate according to a second operation parameter corresponding to the refrigeration mode for a preset time length, so as to reduce the viscosity of the lubricating oil in the refrigerant circulation system.

[0066] The second operation parameter comprises: setting the opening degree of the electronic expansion valve to the maximum opening degree, and controlling the fan of the indoor unit to be turned off.

[0067] Exemplarily, based on the above statements, it can be known that before the air conditioner performs heating, the viscosity of the lubricating oil in the refrigerant circulation system needs to be reduced by operating in the refrigeration mode, and the refrigeration mode operated after the rapid heating function is started needs to turn off the fan of the indoor unit, so as to avoid affecting the user, and at the same time, in order to improve the temperature rising speed of the lubricating oil, the opening degree of the electronic expansion valve also needs to be adjusted to the maximum, i.e., the second operation parameter.

[0068] It should be noted that the second operation parameter is different from the operation parameter corresponding to the normal refrigeration mode, and the rest of the operation parameters (such as the operation frequency of the compressor) can refer to the operation parameter corresponding to the normal refrigeration mode.

[0069] For example, as shown in FIG. 4, after the rapid heating function is started, the air conditioner needs to be controlled to operate in the refrigeration mode for 30 seconds at the maximum opening degree of the electronic expansion valve, so as to reduce the viscosity of the lubricating oil in the refrigerant circulation system. Figure 3

[0070] Specifically, after the step 202a, the step 202 can further include the following step 202b:

[0071] The step 202b comprises: controlling the working mode of the air conditioner to be adjusted from the refrigeration mode to the heating mode, and operating according to the first operation parameter.

[0072] The first operation parameter comprises: setting the opening degree of the electronic expansion valve to the minimum opening degree, and keeping the fan of the indoor unit in the off state.

[0073] ​Exemplarily, after the viscosity of the lubricating oil in the refrigerant circulation system is reduced, the air conditioner can be controlled to run in the heating mode to quickly raise the ambient temperature of the indoor environment.

[0074] It should be noted that the first operating parameter is different from the operating parameter corresponding to the normal heating mode, and the remaining operating parameters (such as the operating frequency of the compressor) can refer to the operating parameter corresponding to the normal heating mode.

[0075] It should be noted that, since the air conditioner runs in the refrigeration mode for a preset time period before heating, a low-temperature area is formed near the indoor heat exchanger, and therefore, the indoor heat exchanger needs to be preheated first, and air is supplied to the indoor environment after the temperature rises.

[0076] Specifically, after the step 202b, the step 202 can further include the following steps 202c1 and 202c2.

[0077] The step 202c1 acquires the coil temperature of the indoor unit coil.

[0078] The step 202c2 controls the air conditioner to run according to the third operating parameter corresponding to the heating mode when the difference between the coil temperature and the indoor ambient temperature is greater than a third threshold value.

[0079] The third operating parameter includes controlling the fan of the indoor unit to be turned on.

[0080] It should be noted that the third operating parameter is different from the operating parameter corresponding to the normal heating mode, and the remaining operating parameters (such as the operating frequency of the compressor) can refer to the operating parameter corresponding to the normal heating mode.

[0081] In a possible implementation manner, the indoor unit coil can have a certain temperature difference, that is, one end is hot and the other end is cold. At this time, the temperatures of the two ends of the coil can be acquired respectively, and whether the air supply condition is met can be determined according to the temperatures of the two ends of the coil.

[0082] Specifically, the step 202c1 can include the following steps 202c11 and 202c12.

[0083] The step 202c11 acquires the front-end temperature and the rear-end temperature of the indoor unit coil.

[0084] The step 202c12 calculates an average temperature value of the front-end temperature and the rear-end temperature, and determines the average temperature value as the coil temperature.

[0085] The front-end temperature is the temperature of the indoor unit coil close to the end where the refrigerant enters the indoor heat exchanger, and the rear-end temperature is the temperature of the indoor unit coil close to the end where the refrigerant is discharged from the indoor heat exchanger.

[0086] Specifically, based on the steps 202c11 and 202c12, the step 202c2 can further include the following step 202c21:

[0087] The step 202c21 controls the air conditioner to operate according to the third operating parameter corresponding to the heating mode when the difference between the temperature of the coil and the indoor ambient temperature is greater than the third threshold value and the difference between the front end temperature and the rear end temperature is less than the fourth threshold value.

[0088] For example, as shown in FIG. 30, after the air conditioner operates in the cooling mode for 30 seconds, the air conditioner is controlled to operate in the heating mode at the minimum opening degree of the electronic expansion valve, and at this time, the fan of the indoor unit is kept in the off state. The indoor ambient temperature T2 and the temperature T3 of the coil of the indoor unit are detected in real time, and the fan of the indoor unit is controlled to operate when T3>T2+10℃. Then, the air conditioner can operate in the heating mode according to the normal operating parameter (including the operating frequency of the compressor, the opening degree of the electronic expansion valve, etc.) corresponding to the heating mode.
