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. In the case of a variable split state, the split state is adjusted in the cooling in the heat exchanger of the air conditioner. In the case of the fixed split state, the split state of the refrigerant in the heat exchanger of the air conditioner is fixed.
The split state is divided into single-path split and multi-path split, and refrigerant multi-path split in the outdoor heat exchanger of the air conditioner works under the condition of multi-path split. Under the condition of single-way split flow, the refrigerant in the outdoor heat exchanger of the air conditioner works in a single way. That is, the air conditioner is switched between the single-path split and the multi-path split in the variable split state, and is fixed to operate as the single-path split or the multi-path split in the fixed split state.
When the multi-way flow is split, the reversing valve 3 is positioned at a first station, 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 second split line 2, and the fourth communication port 34 communicates with the first split line 1. The refrigerant of the refrigerant inlet enters from the second diversion pipeline 2, and the one-way valve 10 is arranged in part of the pipelines in the first diversion pipeline 1, so that the refrigerant can only exchange heat and discharge in part of the heat exchange pipeline 4 under the limitation of the one-way valve, and the heat exchange pipeline can be reduced at the moment.
In this embodiment, two heat exchange pipelines 4 are taken as an example, and are a first heat exchange pipeline and a second heat exchange pipeline respectively. The first shunt pipeline 1 and the second shunt pipeline 2 are respectively provided with a main pipeline and two branch pipelines. One branch pipe in the first diversion pipeline 1 is provided with a one-way valve 10. It is assumed that the one-way valve 10 is provided in only one of the branch lines of the first shunt line 1
When the multi-way flow is split, the reversing valve 3 is positioned at a first station, 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 shunt line 1, and the fourth communication port 34 communicates with the second shunt line 2.

At this time, the second communication port 32 communicates with the second split line 2, and the fourth communication port 34 communicates with the first split line 1. The refrigerant of the refrigerant inlet enters from the second diversion pipeline 2, and the one-way valve 10 is arranged in the branch pipeline in the first diversion pipeline 1, so that the refrigerant can only exchange heat and discharge in the first heat exchange pipeline 4 under the limitation of the one-way valve, and only exchanges heat through one heat exchange pipeline 4 at the moment.
As shown in fig. 3, the control method of the air conditioner preheating includes the following steps:
step S310: and under the condition that the compressor of the air conditioner is preheated, acquiring the ambient temperature of the scene where the air conditioner is positioned.
After the air conditioner is started, if a user selects a preheating mode of the air conditioner, acquiring the environment temperature of a scene where the air conditioner is positioned.
Step S320: the operating state of the air conditioner is controlled based on the ambient temperature.
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 the first preset interval, adjusting the air conditioner to be in a fixed split state. In the case of the fixed split state, the split 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 split state. Wherein the temperature of the second preset interval is lower than that of the first preset interval. In the case of a variable split state, the split state is adjusted in the cooling in the heat exchanger of the air conditioner.
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 assumed to be below-3 ℃, because the difference between the ambient temperature and the preset temperature is smaller, the heat loss of the air conditioner during preheating is not required to be reduced, the air conditioner can be preheated normally, the split state of the air conditioner is not required to be adjusted, and the air conditioner is adjusted to be in a fixed split state.
If the ambient temperature is-10 ℃, the air conditioner is adjusted to be in a variable split state in order to ensure the preheating effect because the difference between the ambient temperature and the preset temperature is large, the split state of the air conditioner is adjusted, the heat loss of the air conditioner during preheating is reduced, and the corresponding preheating effect is not directly influenced.
According to the control method for preheating the air conditioner, 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 running state of the air conditioner is controlled according to the ambient temperature, the air conditioner is switched between a variable shunting state and a fixed shunting state, the shunting 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 a variable split state includes:
step 410: and acquiring the current split state of the air conditioner.
And when the difference between the dew point temperature and the coil temperature is large, acquiring the split state of the indoor heat exchanger and/or the outdoor heat exchanger of the air conditioner. The shunt state includes: single-pass splitting and multi-pass splitting.
Step 420: if the air conditioner is in the single-way split, the air conditioner continues to work in the single-way split.
After the split state is obtained, the split state of the heat exchanger is adjusted, so that the heat exchanger is switched between single-path split or multi-path split. If the indoor heat exchanger and/or the outdoor heat exchanger are/is in the single-way split, the operation is continued by the single-way split.
Three or four heat exchange pipelines can be arranged according to the needs, so that the split state can be also provided with the intermediate state of partial split so as to ensure that the selection is carried out according to the needs in the operation process.
Step 430: if the air conditioner is in multi-path split, the air conditioner is adjusted to be in single-path split for working.
And if the indoor heat exchanger and/or the outdoor heat exchanger are/is in multi-way split flow, adjusting the indoor heat exchanger and/or the outdoor heat exchanger to work in single-way split flow. If the air conditioner is also provided with a middle device for partial diversion, the state of multipath diversion can be adjusted to the state of partial diversion, and the heat exchange is carried out by utilizing a partial heat exchange pipeline. For example, when the air conditioner is provided with three branches, if the air conditioner is in the three branches, if the difference between the ambient temperature and the preset temperature is found to be larger, the air conditioner is adjusted to be two branches, and if the difference between the ambient temperature and the preset temperature is still larger, the air conditioner is adjusted to be one branch. And the indoor heat exchanger and/or the outdoor heat exchanger are/is adjusted to work for single-way split flow, so that the heat loss of the air conditioner during preheating is reduced.
After the split state of the air conditioner is adjusted, the indoor fan and/or the outdoor fan of the air conditioner are/is controlled to stop or reduce rotation in order to further reduce heat loss, 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 as to ensure the temperature of the refrigerant.
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 comprises:
step 510: the time of the compressor operation is obtained.
After the split state is adjusted, the time for the compressor to run after adjustment is obtained.
Step 520: and controlling the compressor to be closed under the condition that the running time of the compressor reaches the first preset time.
In case that the operation time of the compressor reaches the first preset time, the compressor is controlled to stop operating in order to reduce the energy consumption. For example, when the compressor run time reaches 5 minutes, the temperature has reached a 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 comprises:
step 530: and obtaining the idle time of the compressor.
And after the compressor is controlled to be closed, acquiring the idle time of the closing of the compressor.
Step 540: and returning to the step of acquiring the environmental 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.
Under the condition that the idle time of the compressor reaches the second preset time, in order to ensure the temperature of the compressor, the compressor is controlled to be started, the compressor is restarted to be preheated, and the environment temperature of the scene where the air conditioner is located is acquired again. And based on the re-acquired environmental temperature, comparing the re-acquired environmental temperature with a preset temperature, 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 turned on to re-warm up in order to avoid excessive temperature drop.
