Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following describes in detail the operation principle of the air conditioner according to the embodiment of the present application:
as shown in fig. 1, the compressor compresses a refrigerant (refrigerant), and sends the compressed refrigerant to the condenser through a pipe, and the high-temperature and high-pressure gaseous refrigerant releases heat in the condenser to change the gaseous refrigerant into a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is reduced in pressure by a capillary tube (throttle unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low temperature and low pressure liquid refrigerant is delivered to the evaporator where it evaporates from a liquid to a gas and absorbs 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 used for refrigerating, the heat exchanger of the outdoor unit is a condenser, and the heat exchanger of the indoor unit is an evaporator; on the contrary, when the air conditioner heats, the heat exchanger of the outdoor unit is an evaporator, and the heat exchanger of the indoor unit is a condenser.
The main difference between the heating mode and the rapid heating mode of the air conditioner is their heating speed and energy consumption.
The heating mode is a basic working mode in an air conditioning system, and the indoor temperature is improved by absorbing indoor low-temperature air through an indoor unit and blowing hot air out after heating treatment. The heating mode is usually constant temperature heating, so that the indoor temperature can be stably increased to the set temperature; meanwhile, the energy consumption of the heating mode is low, because it only needs to maintain stable heating power.
The fast heating mode refers to a fast heating function provided by an air conditioning system under special conditions, and increases the heating power of an indoor unit to increase the indoor temperature. Compared with a heating mode, the heating speed of the rapid heating mode is higher, and the indoor temperature can be increased to the required temperature in a short time; but at the same time the energy consumption of the fast heating mode is also higher, because it requires more energy to provide more heating power. In short, the heating mode is suitable for scenes with low temperature requirements in general, and the rapid heating mode is suitable for scenes needing rapid heating, but the energy consumption is correspondingly increased.
Aiming at the technical problems of high energy consumption and low heating speed of a rapid heating mode in the related art, the embodiment of the application provides a rapid heating method of an air conditioner, which can rapidly raise the indoor environment temperature through a reasonable control strategy under lower energy consumption.
The rapid heating method of the air conditioner provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 2, the method for quickly heating an air conditioner according to the embodiment of the present application may include the following steps 201 and 202:
step 201, receiving a target instruction for starting the rapid heating function, and judging whether the target environmental parameter meets a preset temperature condition.
Wherein the target environmental parameter comprises at least one of: indoor and outdoor environment temperature difference.
The target instruction is used for triggering the rapid 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 and the like, or can be automatically triggered by the system according to an automatic flow.
After receiving the target instruction, the air conditioner first needs to determine whether the environmental parameter of the current environment meets the starting condition of the rapid heating function provided by the embodiment of the application, that is, whether the target environmental parameter meets the preset temperature condition.
It should be noted that, because the rapid heating method of the air conditioner provided by the embodiment of the application mainly improves the heat exchange efficiency by reducing the viscosity of the lubricating oil in the refrigerant circulation system and improving the circulation efficiency of the refrigerant and the lubricating oil in the low-temperature environment in winter, thereby realizing rapid heating. Therefore, before the rapid heating mode provided by the embodiment of the present application is started, it is necessary to determine whether the environmental parameters of the current environment satisfy the starting conditions of the rapid heating function provided by the embodiment of the present application.
It will be appreciated that the viscosity of the lubricant is inversely proportional to the temperature, and the lower the temperature, the higher the viscosity of the lubricant, and therefore, when the outdoor ambient temperature is low, or the indoor and outdoor ambient temperature difference is large, the viscosity of the lubricant in the outdoor heat exchanger tube is high, greatly affecting the circulation efficiency of the refrigerant and lubricant. Therefore, when the viscosity of the lubricating oil in the outdoor heat exchanger pipeline is judged to be high, the temperature of the lubricating oil in the outdoor heat exchanger pipeline needs to be increased in a mode of conveying heat to the outdoor heat exchanger so as to reduce the viscosity of the lubricating oil, accelerate the oil return speed of the compressor and shorten the oil return time, so that heating can be performed more quickly.
The lubricant is a lubricant in the compressor, and the lubricant in the compressor enters the circulation system of the refrigerant during the operation of the air conditioner. When heating is performed in a low-temperature environment, viscosity of lubricating oil in the outdoor heat exchanger increases, and a reflux speed is slow, which affects operation efficiency of the compressor and circulation efficiency of the refrigerant.
Specifically, the step 201 of determining whether the target environmental parameter meets the preset temperature condition may include the following steps 201a1 and 201a2:
step 201a1, acquiring an indoor environment temperature and the outdoor environment temperature, and calculating the indoor and outdoor environment temperature difference based on the indoor environment temperature and the outdoor environment temperature.
Step 201a2 is to determine that the target environmental parameter meets the preset temperature condition when the indoor and outdoor environmental temperature difference is greater than a first preset threshold and/or the outdoor environmental temperature is less than a second preset threshold.
For example, as shown in fig. 3, after the air conditioner is started, if the air conditioner receives a target instruction to start the rapid heating function, the air conditioner may acquire an indoor environment temperature and an outdoor environment temperature T0 through a temperature sensor, and calculate an indoor and outdoor environment temperature difference T1. And (3) under the condition that T0 is less than 5 ℃ and/or T1 is more than 10 ℃, starting the rapid heating function, otherwise, not starting the rapid heating function by the air conditioner.
And 202, controlling the air conditioner to execute a rapid heating control strategy under the condition that the target environment parameter meets the preset temperature condition.
Wherein, the rapid heating control strategy is used for: the viscosity of lubricating oil in the refrigerant circulation system is reduced and the coil temperature of the indoor unit is increased by changing the working mode.
In an exemplary embodiment of the present application, in order to achieve a rapid increase in indoor ambient temperature, after the air conditioner is turned on and a rapid heating function is performed, no matter what working mode the air conditioner is in, the air conditioner needs to be switched to a cooling mode first, so that a high-temperature refrigerant can enter a heat exchanger of an outdoor unit, the temperature of lubricating oil in the heat exchanger of the outdoor unit is increased, and the viscosity of the lubricating oil is reduced.
After the viscosity of the lubricating oil in the outdoor heat exchanger is reduced, the air conditioner switches the working mode into the heating mode again to raise the coil temperature of the indoor unit, and the raising speed of the coil temperature of the indoor unit is obviously raised compared with that of the normal heating mode due to the increase of the circulation efficiency of the refrigerant and the lubricating oil, so that the indoor environment can be heated quickly.
It should be noted that, based on the operation principle of the air conditioner shown in fig. 1, when the air conditioner is operated in the cooling mode, the indoor heat exchanger is an evaporator, and the refrigerant absorbs heat of the indoor environment in the heat exchange process, so that a low-temperature area is formed near the indoor heat exchanger, and at this time, the air conditioner can close the fan of the indoor unit, so as to avoid affecting the user.
For example, if the target environmental parameter does not meet the preset temperature condition, the rapid heating mode may not be performed.
Illustratively, after the step 201, the method for quickly heating an air conditioner according to the embodiment of the present application may further include the following step 203:
and 203, controlling the air conditioner to keep the current operation mode unchanged under the condition that the target environment parameter does not meet the preset temperature condition.
Specifically, in the step 202, the viscosity of the lubricant in the refrigerant circulation system is reduced, which may include the following step 202a:
step 202a, before the air conditioner operates according to the first operation parameters corresponding to the heating mode, controlling the air conditioner to operate in the cooling mode, and operating for a preset period of time according to the second operation parameters corresponding to the cooling mode, so as to reduce the viscosity of the lubricating oil in the refrigerant circulation system.
Wherein the second operating parameter comprises: the opening of the electronic expansion valve is set to be the maximum opening, and the fan of the indoor unit is controlled to be closed.
As can be seen from the foregoing, the viscosity of the lubricant in the refrigerant circulation system needs to be reduced by operating the cooling mode before the air conditioner heats, and the cooling mode that is operated after the rapid heating function is turned on needs to turn off the fan of the indoor unit, avoiding the influence on the user, and at the same time, in order to increase the temperature rising speed of the lubricant, the opening of the electronic expansion valve needs to be adjusted to be the maximum, that is, the second operation parameter.
It should be noted that, the second operation parameter is an operation parameter that is different from the operation parameter corresponding to the normal cooling mode, and the other operation parameters (such as the operation frequency of the compressor) may refer to the operation parameter corresponding to the normal cooling mode.
For example, as shown in fig. 3, after the rapid heating function is started, the air conditioner is first controlled to operate in the cooling mode for 30 seconds under the maximum opening of the electronic expansion valve, so as to reduce the viscosity of the lubricating oil in the refrigerant circulation system.
Specifically, after the step 202a, the step 202 may further include the following step 202b:
step 202b, controlling the working mode of the air conditioner to be adjusted from a refrigeration mode to a heating mode, and operating according to the first operation parameter.
Wherein the first operating parameter comprises: the opening of the electronic expansion valve is set to be the minimum opening, and the fan of the indoor unit is controlled to be kept in a closed state.
For example, after the viscosity of the lubricant oil in the refrigerant circulation system is reduced, the air conditioner may be controlled to operate in a heating mode to rapidly raise the ambient temperature of the indoor environment.
It should be noted that, the first operation parameter is an operation parameter that is different from the operation parameter corresponding to the normal heating mode, and the other operation parameters (such as the operation frequency of the compressor) may refer to the operation parameter corresponding to the normal heating mode.
It should be noted that, since the air conditioner operates in the cooling mode for a preset period of time before heating, a low temperature region is formed near the indoor heat exchanger, it is necessary to preheat the indoor heat exchanger first and supply air to the indoor environment after the temperature rises.
Specifically, after the step 202b, the step 202 may further include the following steps 202c1 and 202c2:
step 202c1, obtaining a coil temperature of the indoor unit coil.
And 202c2, controlling the air conditioner to operate according to a third operation parameter corresponding to the heating mode under the condition that the difference value between the coil temperature and the indoor environment temperature is larger than a third threshold value.
Wherein the third operating parameter comprises: and controlling the fan of the indoor unit to be started.
It should be noted that, the third operation parameter is an operation parameter that is different from the operation parameter corresponding to the normal heating mode, and the other operation parameters (such as the operation frequency of the compressor) may refer to the operation parameter corresponding to the normal heating mode.
In one possible implementation manner, the indoor unit coil may have a certain temperature difference, that is, one end is hot and the other end is cool, at this time, the temperatures of the two ends of the coil may be collected respectively, and whether the air supply condition is met may be judged according to the temperatures of the two ends of the coil.
Specifically, the step 202c1 may include the following steps 202c11 and 202c12:
step 202c11, acquiring the front end temperature and the rear end temperature of the indoor unit coil.
Step 202c12, calculating an average temperature value of the front end temperature and the back end temperature, and determining the average temperature value as the coil temperature.
Wherein the front end temperature is the temperature of one end of the indoor unit coil, which is close to the end of the refrigerant entering the indoor heat exchanger; the rear end temperature is the temperature of one end of the indoor unit coil, which is close to the end of the refrigerant discharged out of the indoor heat exchanger.
Specifically, based on the step 202c11 and the step 202c12, the step 202c2 may further include the following step 202c21:
step 202c21, controlling the air conditioner to operate according to a third operation parameter corresponding to the heating mode when the difference between the coil temperature and the indoor environment temperature is greater than a third threshold value and the difference between the front end temperature and the rear end temperature is less than a fourth threshold value.
For example, as shown in fig. 3, after the cooling mode is operated for 30 seconds, the air conditioner is controlled to operate in the heating mode under the minimum opening degree of the electronic expansion valve, and at this time, the fan of the indoor unit is maintained in the off state. And detecting the indoor environment temperature T2 and the indoor unit coil temperature T3 in real time, and controlling the fan of the indoor unit to run under the condition that T3 is more than T2+10 ℃. Then, the air conditioner can be controlled to operate in the heating mode according to the operation parameters (including the operation frequency of the compressor, the opening of the electronic expansion valve and the like) corresponding to the normal heating mode.
According to the air conditioner rapid heating method provided by the embodiment of the application, after the air conditioner receives the target instruction of starting the rapid heating function, the temperature difference between the indoor environment and the outdoor environment is judged, and/or whether the outdoor environment temperature meets the preset temperature condition or not is judged, and under the condition that the temperature difference between the indoor environment and the outdoor environment is or is met, the air conditioner is controlled to reduce the viscosity of lubricating oil in a refrigerant circulation system and improve the coil temperature of an indoor unit in a mode of changing the working mode. Therefore, the indoor environment temperature of the air conditioner can be quickly improved through a reasonable control strategy under lower energy consumption.
