The embodiment that accompanying drawing describes is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the control method of Fig. 1 detailed description air conditioning system according to embodiments of the present invention, wherein air conditioning system
Including multiple stage indoor set, every indoor set includes the adjustable restricting element of indoor heat exchanger, indoor fan and aperture, every indoor
Facility have anti-cool wind mode and heating mode.Alternatively, restricting element is electric expansion valve.
It is understood that air conditioning system also includes off-premises station, every indoor set is connected cold with composition one with off-premises station
Matchmaker circulates stream, and when every indoor set freezes or heats, the flow direction of coolant has been prior art, does not just carry out it in detail at this
Thin description.
Anti-cool wind mode refers in a heating mode, when the temperature of indoor heat exchanger is less than a certain temperature, and indoor wind
Office closes, and the only temperature of indoor heat exchanger is higher than this temperature value, and indoor fan just can start, such that it is able to prevent from heating
Time, owing to the coil temperature of indoor heat exchanger is too low but understands blowing cold air after indoor fan startup and affect the comfortableness of user.
The control method of air conditioning system according to embodiments of the present invention, comprises the steps:
S1: open heating mode, number of units N of the indoor set of detection start；
S2: when number of units N >=2 of the indoor set opened, whether every indoor set that detection runs enters into anti-cold wind mould
Formula, as the number of units N ＜ 2 of the indoor set opened, controls indoor set and runs according to the first operational mode；
S3: when having detected that indoor set enters anti-cool wind mode, controls to enter the throttling of the indoor set of anti-cool wind mode
The aperture of element is reduced to predetermined aperture, when having detected that indoor set is introduced into anti-cool wind mode, controls to be introduced into anti-cold wind
The indoor set of pattern runs according to the second operational mode.
Specifically, when air conditioning system opens heating mode, whether the number of units of the indoor set first detecting unlatching is more than
Equal to two, when the number of units of the indoor set opened is more than or equal to two, then whether every the indoor set starting detection operation is opened
Open anti-cool wind mode, when indoor set operation being detected opens anti-cool wind mode, then control to enter into the room of anti-cool wind mode
The aperture of the restricting element of interior machine is reduced to predetermined aperture, such that it is able to got lodged in by the High Temperature High Pressure coolant flow through from off-premises station
Enter in the indoor set of anti-cool wind mode, allow the more heat of coolant transmission to the heat exchanger tube of indoor heat exchanger, and then can make
The temperature of the indoor heat exchanger that must enter the indoor set of anti-cool wind mode raises rapidly.
The control method of air conditioning system according to embodiments of the present invention, when detect multiple indoor set be in running status and
When wherein having indoor set to be in anti-cool wind mode, the aperture controlling to enter the restricting element of the indoor set of anti-cool wind mode reduces,
So that High Temperature High Pressure coolant more flows through the indoor set being in anti-cool wind mode, cause coolant can transmit more
Heat gives the indoor heat exchanger of the indoor set being in anti-cool wind mode, causes the temperature of indoor heat exchanger to raise rapidly, accelerates
The indoor set being in anti-cool wind mode exits the time of anti-cool wind mode, and then the comfortableness improving user is experienced.
In some specific embodiments of the present invention, the control method of air conditioning system also includes step S4, every pre-timing
Between section detection enter into the running status of indoor set of anti-cool wind mode, when indoor set exits anti-cool wind mode, control to exit
The indoor set of anti-cool wind mode runs according to the 3rd operational mode.Preferably, the 3rd operational mode is to control opening of restricting element
Spend and reduce along with the temperature of indoor heat exchanger and increase, such that it is able to regulate the temperature of indoor heat exchanger in real time, it is ensured that heat effect
Really.Alternatively, the span of predetermined amount of time is 2-3 minute.Preferably, predetermined amount of time is 1 minute.May be appreciated
It is that the 3rd operational mode can also is that the element controls such as the coolant pressure according to delivery temperature, pressure at expulsion or indoor heat exchanger
The aperture of the restricting element of indoor set processed.
Preferably, the first operational mode is identical with the second operational mode, such that it is able to reduce the control logic of air conditioning system
Difficulty, it is ensured that air conditioning system reliability of operation.In some specific embodiments of the present invention, the first operational mode is for controlling
The aperture of restricting element reduces along with the temperature of indoor heat exchanger and increases.Of course, it should be understood that the first operational mode is also
It can be the restricting element of the control of element indoor sets such as coolant pressure according to delivery temperature, pressure at expulsion or indoor heat exchanger
Aperture.
In some specific embodiments of the present invention, the second operational mode is to control to be introduced into the indoor set of anti-cool wind mode
Restricting element aperture along with indoor heat exchanger temperature reduce and increase.Of course, it should be understood that the second operational mode
Anti-cool wind mode can also be introduced into according to control of elements such as the coolant pressure of delivery temperature, pressure at expulsion or indoor heat exchanger
The aperture of restricting element of indoor set.
The control method of the air conditioning system according to the specific embodiment of the invention is described in detail below with reference to Fig. 1.
The control method of air conditioning system according to embodiments of the present invention, comprises the steps: to first turn on heating mode, inspection
Whether number of units N surveying the indoor set opened is more than or equal to 2, if N >=2, has then detected whether that indoor set enters into anti-cold wind
Pattern.If N ＜ 2, then the aperture of the restricting element controlling indoor set reduces along with the temperature of indoor heat exchanger and increases.
When having detected that indoor set enters into anti-cool wind mode, then control to enter into the joint of the indoor set of anti-cool wind mode
The aperture of fluid element is reduced to predetermined aperture.When detection has indoor set to be introduced into anti-cool wind mode, then control to be introduced into
The aperture of the restricting element of the indoor set of anti-cool wind mode reduces along with the temperature of indoor heat exchanger and increases.
The running status of the indoor set of anti-cool wind mode is entered into, when indoor set exits anti-cold wind mould every detection in 1 minute
During formula, then control the aperture exiting the restricting element of the indoor set of anti-cool wind mode and reduce along with the temperature of indoor heat exchanger and increase
Greatly.When indoor set being detected still in anti-cool wind mode, then control to be in the restricting element of the indoor set of anti-cool wind mode
Aperture is maintained at predetermined aperture.
The control method of air conditioning system according to embodiments of the present invention, enters into the indoor set of anti-cool wind mode by control
Restricting element aperture reduce so that High Temperature High Pressure coolant more flows through the indoor set being in anti-cool wind mode, causes cold
Matchmaker can transmit more heat to the coil pipe of indoor heat exchanger, causes the coil temperature of indoor heat exchanger to raise rapidly, accelerates
Indoor set exits the time of anti-cool wind mode, and then the comfortableness improving user is experienced.
