Brief description
Fig. 1 is a kind of throttle part switching device structural representation in the present invention；
Detailed description of the invention
A kind of throttle part switching device that the present invention provides, can effectively realize cutting between air-cooled ducted air conditioner and new blower fan
Change.
Refer to Fig. 1, a kind of throttle part switching device in the present invention, including：
The new blower fan throttle capillary tube 1 being connected in parallel in circuit and air-cooled ducted air conditioner throttle capillary tube 2；
Connect on new blower fan throttle capillary tube 1 first magnetic valve 4；
Connect on air-cooled ducted air conditioner throttle capillary tube 2 second magnetic valve 5.
In the present embodiment, due to new blower fan and air-cooled ducted air conditioner, to only have restriction different, therefore, when the first magnetic valve 4 closes, and
When two magnetic valves 5 disconnect, new blower fan throttle capillary tube 1 accesses in circuit, and now system is new blower fan pattern, in like manner, when second
Magnetic valve 5 closes, and when the first magnetic valve 4 disconnects, air-cooled ducted air conditioner throttle capillary tube 2 accesses in circuit, and now system is air-cooled ducted air conditioner
Pattern.It is achieved thereby that freely switch air-cooled ducted air conditioner and the effect of new blower fan pattern, effectively solve upper above-mentioned technical problem.
This device also includes unloader 3, and this unloader 3 and new blower fan throttle capillary tube 1 and air-cooled ducted air conditioner throttle capillary tube 2 are simultaneously
Connection is in circuit.
It should be noted that unloader is under certain condition, the valve of hydraulic pump off-load can be made.Unloader is typically one
It with the overflow valve of two position two-way valve, is used as initialization system principal pressure when function is not off-load, when unloading condition pressure oil directly returns
Oil return box, pressure fuel pump drops to be approximately zero, to realize some circuit controls and to improve oil pump life, reduces power consumption.Returning
Road belongs to and entry loop.Pressure-reducing valve is used for adjusting executive component desirable pressure, connects in the loop, typically can not be mutual
Change use.
This unloader 3 including but not limited to mechanical type automatically controls one-way load releasing valve.
The present invention also provides a kind of throttling method, applies the above-mentioned throttle part switching device stated, including：
When unit makees new blower fan, in big cold operating mode, within the temperature range of 38-50 DEG C, big thermal condition, the temperature of 18-30 DEG C
In the range of degree, the first magnetic valve 4 powers on, and the second magnetic valve 5 powers on, and is now equivalent to increase capillary inner diameter, can play fall
The effect of low high side pressure, if pressure also raises further, then opens unloader, again carries out pressure release；Under other operating modes, the
One magnetic valve 4 powers on, the second magnetic valve 5 power-off；
When unit does air-cooled ducted air conditioner, in big cold operating mode, within the temperature range of 38-48 DEG C, big thermal condition, the temperature of 18-30 DEG C
