First valve of unit is closed, the second valve and the 3rd valve are opened.
If the series that road unit is changed in refrigerant heating changes road control module 211 in outdoor machine of air-conditioner for multistage, off-position
Complete heating mode commutation and after the second duration threshold value, road list is changed from the first order refrigerant heating nearest apart from air-conditioner host
Member starts, and the first valve for controlling multistage refrigerant heating to change road unit successively is opened, the second valve and the 3rd valve are closed, and
When the first valve opening, the second valve and the closing of the 3rd valve of road unit are changed in the heating of one-level refrigerant under control, control is current
The first valve that road unit is changed in level refrigerant heating is closed, the second valve and the 3rd valve are opened, so that outdoor machine of air-conditioner output is cold
The distribution pipeline that matchmaker changes road unit by refrigerants at different levels heating successively returns to outdoor machine of air-conditioner.
Off-position changes road control module 211 if it is determined that when liquid pipe temperature reaches the first refrigerant temperature threshold value and continued
Length reaches the 3rd duration threshold value, then controls the heating of next stage refrigerant to change the first valve opening of road unit, the second valve and the 3rd
Valve is closed.Off-position change road control module 211 control afterbody refrigerant heating change road unit the first valve open,
After second valve and the 3rd valve are closed, if it is determined that liquid pipe temperature reaches the first refrigerant temperature threshold value and duration reaches
To the 3rd duration threshold value, then the first valve for controlling multistage refrigerant heating to change road unit is closed, the second valve and the 3rd valve are beaten
Open, so that the refrigerant of outdoor machine of air-conditioner output returns to outdoor machine of air-conditioner by air-conditioning internal machine.
In one embodiment, second environment temperature threshold can be configured according to design requirement, be, for example, -15 DEG C.
First duration threshold value, the second duration threshold value and the 3rd duration threshold value can also be configured according to design requirement, such as when first
Long threshold value is 2 hours, the second duration threshold value is 10 minutes, the 3rd duration threshold value is 5 minutes.First refrigerant temperature threshold value can root
It is configured according to design requirement, for example, 40 DEG C.
As shown in figure 4, when ＜ -15 DEG C of the environment temperature of outdoor machine of air-conditioner, or outdoor machine of air-conditioner ＜ -15 DEG C of environment temperature simultaneously
And the power-off duration of air-conditioner set, more than 4 hours, after start heating order is received, outdoor machine of air-conditioner opens according to normal heating order
Dynamic, the 10min after outdoor machine of air-conditioner completes heating mode commutation, off-position changes road control module 211 and controls first order refrigerant to add
The first single valve 42 of Re Huan roads is opened, the second valve 43 and the 3rd valve 44 are closed, so that the refrigerant warp of outdoor machine of air-conditioner output
Cross the return outdoor machine of air-conditioner of distribution pipeline 41 that road unit is changed in the heating of first order refrigerant.
When it is determined that liquid pipe temperature reaches 40 DEG C and continues 5 minutes, then off-position changes road control module 211 and controls the second level
The first valve 46 that road list is changed in refrigerant heating is opened, the second valve 47 and the 3rd valve 48 are closed, and is controlling the second refrigerant
When the first valve 46 that road unit is changed in heating is opened, the second valve 47 and the 3rd valve 48 are closed, the refrigerant heating of the control first order
The first valve 42 for changing road unit is closed, the second valve 43 and the 3rd valve 44 are opened, so that the refrigerant warp of outdoor machine of air-conditioner output
Cross the return outdoor machine of air-conditioner of distribution pipeline 45 that road unit is changed in second level refrigerant heating.
The first valve 46 that road unit (road unit is changed in refrigerant heating in the second level) is changed in control afterbody refrigerant heating is beaten
Open, after the closing of the second valve 47 and the 3rd valve 48, if it is determined that liquid pipe temperature reaches 40 DEG C and continues 5min, then controls two
The first valve 42,46 that road unit is changed in level refrigerant heating is closed, the second valve 43,47 and the 3rd valve 44,48 are opened, so that empty
