The invention provides a control method for preheating 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 communication port 31, a second communication port 32, a third communication port 33, and a fourth communication 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. Under the condition of fixed flow dividing state, the flow dividing state of the refrigerant in the 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 is fixed to operate in the one-way split or the 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 the 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 in the first heat exchange pipeline 4 and be discharged 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 the air conditioner preheating includes the following steps:
step S310: and acquiring the ambient temperature of the scene where the air conditioner is positioned under the condition that the compressor of the air conditioner is preheated.
After the air conditioner is started, if a user selects a preheating mode of the air conditioner, the ambient temperature of a scene where the air conditioner is located is obtained.
Step S320: and controlling the running state of the air conditioner based on the ambient temperature.
And after the ambient temperature is obtained, comparing the ambient temperature with a preset temperature, and controlling the running state of the air conditioner. And if the difference value between the ambient temperature and the preset temperature is in a first preset interval, adjusting the air conditioner to be in a fixed shunting state. Under the condition of fixed flow dividing state, the flow dividing state of the refrigerant in the heat exchanger is fixed.
And if the difference value between the ambient temperature and the preset temperature is in a second preset interval, adjusting the air conditioner to be in a variable shunting state. Wherein the temperature of the second preset interval is lower than the temperature of the first preset interval. Under the condition of variable shunt state, the refrigerant in the heat exchanger of the air conditioner adjusts the shunt state.
Specifically, when the preset temperature is 4 ℃, if the ambient temperature is-1 ℃, the first preset interval is assumed to be-5 to 0 ℃, and the second preset interval is below-3 ℃, because the difference between the ambient temperature and the preset temperature is small, the heat loss of the air conditioner during preheating does not need to be reduced, the air conditioner can be normally preheated, and the air conditioner is adjusted to be in a fixed shunting state without adjusting the shunting state of the air conditioner.
If the ambient temperature is-10 ℃, because the difference value between the ambient temperature and the preset temperature is large, in order to ensure the preheating effect, the air conditioner is adjusted to be in a variable shunt state, the shunt state of the air conditioner is adjusted, the heat loss of the air conditioner during preheating is reduced, but the corresponding preheating effect cannot be directly influenced.
According to the air conditioner preheating control method provided by the invention, under the condition that the compressor of the air conditioner is preheated, the ambient temperature of the scene where the air conditioner is located is firstly obtained, and then the running state of the air conditioner is controlled based on the ambient temperature, so that the air conditioner is switched between the variable shunt state and the fixed shunt state, the shunt state of the heat exchanger is changed, the heat loss of the air conditioner during preheating is reduced, and the loss of the compressor is reduced.
Based on the above embodiment, as shown in fig. 4, the step of adjusting the air conditioner to the variable split state includes:
step 410: and acquiring the current shunting state of the air conditioner.
And when the difference between the dew point temperature and the coil temperature is large, acquiring the shunting state of the indoor heat exchanger and/or the outdoor heat exchanger of the air conditioner. The shunting state comprises the following steps: single-pass shunting and multi-pass shunting.
Step 420: and if the air conditioner is in single-path shunting, continuously working by the single-path shunting.
And after the shunting state is obtained, the shunting state of the heat exchanger is adjusted to enable the heat exchanger to be switched between single-path shunting or multi-path shunting. And if the indoor heat exchanger and/or the outdoor heat exchanger are/is in single-path shunting, the indoor heat exchanger and/or the outdoor heat exchanger continue to work by single-path 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 430: if the air conditioner is in multi-path shunting, the air conditioner is adjusted to single-path shunting to work.
And if the indoor heat exchanger and/or the outdoor heat exchanger are/is in multi-path shunting, adjusting the indoor heat exchanger and/or the outdoor heat exchanger to be in single-path shunting for working. If the air conditioner is also provided with a partial shunting intermediate device, the state of multipath shunting can be adjusted to a partial shunting state, and partial heat exchange pipelines are utilized for heat exchange. For example, when the air conditioner is provided with three shunts in total, if the three shunts are present, if the difference between the ambient temperature and the preset temperature is found to be large, the three shunts are adjusted to be two shunts, and if the difference between the ambient temperature and the preset temperature is still large, the three shunts are adjusted to be one shunt. The indoor heat exchanger and/or the outdoor heat exchanger are/is adjusted to work in a one-way shunting mode, and the heat loss of the air conditioner during preheating is reduced.
After the flow dividing state of the air conditioner is adjusted, in order to further reduce the heat loss, the indoor fan and/or the outdoor fan of the air conditioner are controlled to stop or reduce the rotation, and the heat loss of the indoor heat exchanger and/or the outdoor heat exchanger is reduced by closing or reducing the indoor fan and/or the outdoor fan, so that the temperature of the refrigerant is ensured.
Based on the above embodiments, in an alternative embodiment, as shown in fig. 5, step S320: the step of controlling the operation state of the air conditioner based on the ambient temperature further includes:
step 510: and acquiring the running time of the compressor.
And after the flow splitting state is adjusted, acquiring the running time of the compressor after adjustment.
Step 520: and controlling the compressor to be closed under the condition that the running time of the compressor reaches a first preset time.
And under the condition that the running time of the compressor reaches the first preset time, controlling the compressor to stop running in order to reduce energy consumption. For example, when the compressor operation time reaches 5 minutes, the temperature has reached the preset temperature, and the compressor is controlled to be turned off.
Based on the above embodiment, as shown in fig. 5, step S320: the step of controlling the operation state of the air conditioner based on the ambient temperature further includes:
step 530: and acquiring the idle time of the compressor.
And acquiring the idle time of the compressor closing after controlling the compressor to close.
Step 540: and returning to the step of acquiring the ambient temperature of the scene where the air conditioner is located under the condition that the compressor of the air conditioner is preheated under the condition that the idle time of the compressor reaches the second preset time.
And under the condition that the idle time of the compressor reaches the second preset time, controlling the compressor to be started in order to ensure the temperature of the compressor, enabling the compressor to enter preheating again, and acquiring the ambient temperature of the scene where the air conditioner is located again. And comparing the acquired environmental temperature with the preset temperature based on the acquired environmental temperature again, and controlling the running state of the air conditioner.
For example, when the idle time of the compressor reaches 20 minutes, the compressor is controlled to be started to re-preheat the compressor in order to avoid excessive temperature drop.
The following describes a control system for air conditioner preheating according to an embodiment of the present invention, and the control system for air conditioner preheating described below and the control method described above may be referred to in correspondence.
