The invention provides a control method for self-cleaning of an air conditioner, wherein the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner and the like.
As shown in fig. 1 and 2, the indoor heat exchanger or the outdoor heat exchanger of the air conditioner is provided with a variable flow dividing device, and the indoor heat exchanger and the outdoor heat exchanger can be provided with the variable flow dividing device at the same time, and the variable flow dividing device comprises: the system comprises a reversing valve 3, a first shunt pipeline 1, a second shunt pipeline 2 and at least two heat exchange pipelines 4. The first tapping line 1 is connected to the second tapping line 2 via at least two heat exchange lines 4. The first branch pipeline 1 and the second branch pipeline 2 are respectively provided with a main pipeline and a plurality of branch pipelines, and a one-way valve 10 can be arranged in the middle branch pipeline according to requirements.
The change valve 3 is a two-position four-way change valve, and is provided with a first communicating port 31, a second communicating port 32, a third communicating port 33 and a fourth communicating port 34, and the change valve 3 has a first station and a second station. The first communication port 31 is connected to the refrigerant inlet, and the third communication port 33 is connected to the refrigerant outlet.
The air conditioner has a variable split state and a fixed split state. Under the condition of variable shunt state, the refrigerant in the heat exchanger of the air conditioner adjusts the shunt state according to the working mode of the air conditioner. Under the condition of fixed shunting state, the shunting state of the refrigerant in the outdoor heat exchanger of the air conditioner is fixed.
The shunting state is divided into single-path shunting and multi-path shunting, and under the condition of multi-path shunting, refrigerant in the outdoor heat exchanger of the air conditioner is subjected to multi-path shunting to work. Under the condition of single-path flow division, the refrigerant in the outdoor heat exchanger of the air conditioner works in a single path. That is, the air conditioner switches between the one-way split and the multi-way split in the variable split state, and the air conditioner operates in the fixed-position one-way split or multi-way split in the fixed split state.
When the multi-path flow is divided, the change valve 3 is in the first position, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 is communicated with the fourth communication port 34. At this time, the second communication port 32 communicates with the first branch line 1, and the fourth communication port 34 communicates with the second branch line 2. The refrigerant of the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipelines of the first shunting pipeline 1, respectively enters each heat exchange pipeline 4 to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 by the branch pipelines, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the heat exchange of a plurality of pipelines is realized.
When the one-way flow is branched, the selector valve 3 is in the second position, the first communication port 31 communicates with the fourth communication port 34, and the third communication port 33 communicates with the second communication port 32. At this time, the second communication port 32 communicates with the second branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valves 10 are arranged in part of pipelines in the first shunting pipeline 1, and under the limitation of the check valves, the refrigerant can only be subjected to heat exchange and discharged from part of the heat exchange pipelines 4, and at the moment, the heat exchange pipelines can be reduced.
In this embodiment, taking two heat exchange pipelines 4 as an example, the two heat exchange pipelines are respectively a first heat exchange pipeline and a second heat exchange pipeline. First reposition of redundant personnel pipeline 1 and second reposition of redundant personnel pipeline 2 all are equipped with a trunk line and two spinal branchs way. A one-way valve 10 is arranged in one branch pipeline of the first shunt pipeline 1. It is assumed that the non-return valve 10 is arranged in only one of the conduits of the first tapping line 1
When the multi-path flow is divided, the change valve 3 is in the first position, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 is communicated with the fourth communication port 34. At this time, the second communication port 32 communicates with the first branch line 1, and the fourth communication port 34 communicates with the second branch line 2. The refrigerant at the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipeline of the first shunting pipeline 1, respectively enters the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 from the branch pipeline, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the simultaneous heat exchange of the two pipelines is realized.
When the one-way flow is branched, the selector valve 3 is in the second position, the first communication port 31 communicates with the fourth communication port 34, and the third communication port 33 communicates with the second communication port 32. At this time, the second communication port 32 communicates with the second branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valve 10 is arranged in the branch pipeline in the first shunting pipeline 1, the refrigerant can only exchange heat and be discharged from the first heat exchange pipeline 4 under the limitation of the check valve, and at the moment, the heat exchange is carried out only through one heat exchange pipeline 4.
As shown in fig. 3, the control method of self-cleaning of the air conditioner includes the following steps:
step S110: and controlling the air conditioner to enter a self-cleaning mode under the condition that the self-cleaning condition is met.
After the air conditioner is started, the air conditioner can automatically judge whether the air conditioner meets the self-cleaning condition, for example, judge whether the running time of the air conditioner is greater than a set accumulated running threshold, if the running time is greater than the set accumulated running threshold, the air conditioner meets the self-cleaning condition, and the air conditioner is controlled to enter a self-cleaning mode.
For example, in case of satisfying the self-cleaning condition, the air conditioner is controlled to operate in a cooling mode to self-clean the indoor heat exchanger. The water vapor in the air conditioner is condensed into liquid water by utilizing an indoor heat exchanger of the air conditioner, and the indoor heat exchanger is cleaned by utilizing the liquid water.
Step S120: and acquiring the ambient temperature of the air conditioner and the cold outlet temperature of the heat exchanger.
In the process of cleaning the indoor heat exchanger, the air conditioner control sensor detects the ambient temperature of the current scene, the ambient temperature can be indoor temperature or outdoor temperature, the cold outlet temperature of the indoor heat exchanger is obtained, and the cold outlet temperature is the temperature of a refrigerant at an outlet of the indoor heat exchanger.
Step S130: and adjusting the running state of the air conditioner according to the ambient temperature and the cold outlet temperature.
After the ambient temperature and the cold-out temperature are acquired, the air conditioner is controlled to be switched between a variable shunt state and a fixed shunt state based on the acquired ambient temperature and cold-out temperature. Under the condition of variable shunt state, the refrigerant in the heat exchanger of the air conditioner adjusts the shunt state according to the working mode of the air conditioner; under the condition of fixing the shunting state, the shunting state of the refrigerant in the heat exchanger is fixed.
Specifically, after the ambient temperature and the cold-out temperature are obtained, it is first determined whether the ambient temperature and the cold-out temperature satisfy the working conditions corresponding to the self-cleaning mode. If the working condition corresponding to the self-cleaning mode is met, the air conditioner can normally work in the current shunting state, and the single-path shunting or multi-path shunting can meet the requirement, the air conditioner is controlled to be in the fixed shunting state. In order to reduce energy consumption, the single-path shunt mode can be adopted to work in the process.
If the working condition corresponding to the self-cleaning mode is not met, the air conditioner cannot normally work in the current shunting state, the air conditioner is controlled to be in the variable shunting state, and the shunting state of the refrigerant in the heat exchanger of the air conditioner is adjusted through the reversing valve according to the working mode of the air conditioner. For example, when the air conditioner is in a single-path shunting state, since the air conditioner self-cleaning mode is a refrigeration process, the supercooling section of the air conditioner can be increased by increasing shunting, and the air conditioner is controlled to be switched into multi-path shunting for heat exchange, so that the air conditioner achieves the optimal self-cleaning effect.
The control method for self-cleaning of the air conditioner provided by the invention firstly controls the air conditioner to enter a self-cleaning mode under the condition of meeting the self-cleaning condition, obtains the ambient temperature of the air conditioner and the cold outlet temperature of the heat exchanger in the self-cleaning process of the air conditioner, controls the running state of the air conditioner according to the ambient temperature and the cold outlet temperature, switches the air conditioner between a variable shunting state and a fixed shunting state, changes the shunting state of the heat exchanger, and enables the air conditioner to achieve the best self-cleaning effect.
As shown in fig. 4, the step of determining whether the ambient temperature and the cool-out temperature satisfy the working conditions corresponding to the self-cleaning mode includes:
step S410: and acquiring a first boundary temperature and a second boundary temperature corresponding to the self-cleaning mode.
In the step of judging whether the working condition is met, first, a first boundary temperature and a second boundary temperature corresponding to the self-cleaning mode are obtained. Since the air conditioner self-cleaning mode is a refrigeration process, the first boundary temperature is the limit value of the ambient temperature during refrigeration, and the second boundary temperature is the limit value of the outlet temperature of the evaporator during refrigeration.
Step S420: and judging whether the ambient temperature exceeds a first boundary temperature or not, and judging whether the cooling temperature exceeds a second boundary temperature or not.
After the first boundary temperature and the second boundary temperature are obtained, whether the ambient temperature exceeds the first boundary temperature or not is judged, and whether the cooling temperature exceeds the second boundary temperature or not is judged. If the ambient temperature does not exceed the first boundary temperature and the cold outlet temperature does not exceed the second boundary temperature, the air conditioner can normally work in the current shunting state, and the single-path shunting or multi-path shunting can meet the requirements, and the air conditioner is controlled to be in the fixed shunting state.
And if the ambient temperature exceeds the first boundary temperature or the cooling temperature exceeds the second boundary temperature, or the ambient temperature exceeds the first boundary temperature and the cooling temperature exceeds the second boundary temperature at the same time, which indicates that the air conditioner can not normally work in the current shunting state, controlling the air conditioner to be in the variable shunting state.
For example, assume that the first boundary temperature is 48 degrees celsius and the second boundary temperature is 8 degrees celsius. And if the ambient temperature is greater than 48 ℃ or the cold-out temperature is greater than 8 ℃, controlling the air conditioner to be in a variable flow dividing state. And when the ambient temperature is less than 48 ℃ and the cooling temperature is less than 8 ℃, controlling the air conditioner to be in a fixed shunting state.
If the air conditioner starts the self-cleaning mode and enters the fixed shunt state, the air conditioner operates in the current shunt state, and after the air conditioner starts the self-cleaning mode and enters the variable shunt state, as shown in fig. 5, in order to enhance the self-cleaning mode, the method further includes:
step S510: and acquiring the current shunting state of the air conditioner.
And acquiring the current shunting state of the air conditioner. The shunting state mainly comprises: single-pass shunting and multi-pass shunting. Three or four heat exchange pipelines can be arranged according to the requirement, so that the shunting state can also be set to be a partially shunting intermediate state, and the selection can be carried out according to the requirement in the operation process.
Step S520: if the air conditioner is in single-path shunting, the air conditioner is adjusted to multi-path shunting to work.
The self-cleaning mode is a refrigerating process and is used for cleaning the indoor heat exchanger, so that if the air conditioner is judged to be known to be in single-path shunting, normal work can not be guaranteed due to the current shunting state, the air conditioner is adjusted to be in multi-path shunting to work, a plurality of heat exchange pipelines are utilized for heat exchange, and heat exchange of the pipelines is achieved.
If the air conditioner is also provided with a partial shunting intermediate device, the state of single-path shunting can be adjusted to be a partial shunting state, and partial heat exchange pipelines are utilized for heat exchange.
Step S530: and if the air conditioner is in the multi-path division, keeping the multi-path division to work.
If the air conditioner is already in multi-path shunting, because the multi-path shunting can enhance the refrigeration effect in the self-cleaning mode, the self-cleaning intensity reaches the maximum value, and the multi-path shunting is kept to work.
The following describes the control system for self-cleaning of an air conditioner provided by the embodiment of the present invention, and the control system for self-cleaning of an air conditioner described below and the control method described above may be referred to correspondingly.
As shown in fig. 6, the control system of the self-cleaning of the air conditioner includes: an execution module 610, an acquisition module 620, and an adjustment module 630.
