As it is shown in figure 1, the control method of a kind of air-conditioning device of one embodiment of the present of invention proposition, it includes step
S2: the compressor of air-conditioning device uses the first start-up mode to start, and compressor makes air-conditioning device real when this first start-up mode
The most normally freeze or heat.Wherein, air-conditioning device normally freezes or heats, and refers to that coolant passes through cross valve and follows in air-conditioning device
Ring, makes air-conditioning device refrigeration or heats.
Wherein, as it is shown in figure 1, also needed operating procedure S1 before step S2: the compressor of air-conditioning device at least uses one
Secondary second start-up mode, compressor makes cross valve be in refrigerating state or heat state when the second start-up mode.
In the technical scheme of above-mentioned offer, start compressor by twice, air-conditioning device can be made in normal refrigeration or
Before heating, making cross valve be in refrigerating state or heat state, cross valve is when freezing or heating state, and coolant can be four
Inside logical valve normal through, turn over the parts within stuck cross valve from without punching, enable cross valve properly functioning, thus carry

In a concrete application example, aforesaid compressor, when the second start-up mode, controls the main cunning of cross valve
Valve position when valve is positioned at cross valve air-conditioning device kind of refrigeration cycle or valve position when heating circulation, make cross valve be in refrigerating state
Or heat state.Wherein, owing to the unit of air-conditioning device is shut down under certain heats state, particularly state is heated at low voltage difference
During lower shutdown, the main slide valve in the cross valve of unit can not be completely recovered at refrigerating section, but easily rests in cross valve
Mid portion.In this example, when air-conditioning device is started shooting again, compressor is before the first start-up mode, first by four
The main slide valve of logical valve moves to valve position i.e. refrigerating section during kind of refrigeration cycle, or moves the main slide valve of cross valve to heating circulation
Time the section of heating place, valve position, thus compressor start time, coolant can smoothly pass in cross valve, effectively prevent pressure
During the start of contracting machine, the main slide valve of cross valve is centrally located and turned over valve bowl by coolant punching and cause the stuck hidden danger of quality of cross valve,
And then improve air-conditioning device reliability of cross valve commutation after heating shutdown.
Specifically when implementing, aforesaid step S1 can be: compressor uses the second start-up mode to start, and compressor is the

Valve position, concrete, when the coil blackout of cross valve, compressor can order about main cunning within the opening time of 0.05s to 0.1s
Valve moves to valve position during air-conditioning device refrigeration；When the coil of cross valve is charged, compressor is when the unlatching of 0.05s to 0.1s
In can order about main slide valve and move to valve position when air-conditioning device heats, thus when compressor is opened for a long time, coolant
Cross valve can be flow through swimmingly, without the main slide valve of cross valve is impacted.
In a concrete application example, as in figure 2 it is shown, aforesaid step S2 can be: the compressor of air-conditioning device
Using the first start-up mode to start, compressor makes compressor longtime running after using the first start-up mode.Wherein, compression captain
Phase is run particularly as follows: the operation time of compressor is more than 0.1s.In this example, owing to compressor is before longtime running, i.e.
Cross valve adjusted to refrigerating state or heat state, thus the coolant flowed out from compressor when opening compressor longtime running
Can flow through from cross valve swimmingly, cause main slide valve that stuck exception occurs without impacting the main slide valve of cross valve.Otherwise,
If compressor uses the first start-up mode to make compressor longtime running when starting for the first time, the operation time of compressor is more than
May rush during 0.1s and turn over the valve bowl of main slide valve and cause valve bowl stuck.
Further, in order to save manpower, it is also possible to control pressure by control module such as single-chip microcomputer or microprocessor etc.
Contracting machine uses the first start-up mode to start.
Need exist for explanation: aforementioned control compressor uses the mould that the first start-up mode and the second start-up mode start
Block can be same control module, it is also possible to be different, and being not limited to is separate two modules in physical areas.
Further, as in figure 2 it is shown, also included step before the compressor of air-conditioning device uses the second start-up mode
