The aperture of regulating valve 2, to increase the refrigeration dose in target set of heat exchange tubes.Therefore, after above-mentioned adjustment, subregion can be made to exchange heat
When device assembly is freezed or defrosted, each set of heat exchange tubes 11 is close to mean temperature, multiple regulating valves 2 in heat exchanger body 1
The shunting effect of heat exchanging device ontology 1 is preferable, exchanges heat more uniform.
Further, the aperture of the above-mentioned adjustment correspondingly regulating valve 2 also specifically includes:
When the heat exchanger body of subregion heat exchanger assembly is as outdoor heat exchanger and air conditioner operation heating mode, if
Temperature parameter deviant is greater than or equal to the first tolerance, increases the aperture for adjusting accordingly valve 2, i.e. temperature parameter deviant is big
Show that the outlet temperature of target heat exchange tube refrigerant is excessively high in or equal to the first tolerance, the system in current goal set of heat exchange tubes
Cryogen is very few, needs to increase the aperture of regulating valve 2, to increase the refrigeration dose in target set of heat exchange tubes；If the temperature parameter
Deviant is less than or equal to the second tolerance, reduces the aperture of the correspondingly regulating valve 2, i.e., temperature parameter deviant be less than or
Show the refrigerant that the outlet temperature of target heat exchange tube refrigerant is too low, in current goal set of heat exchange tubes equal to the second tolerance
Excessively, need to reduce the aperture for the regulating valve 2 being connected to target set of heat exchange tubes, to reduce the refrigerant in target set of heat exchange tubes
Amount.Therefore, after above-mentioned adjustment, when subregion heat exchanger assembly can be made to be heated, each set of heat exchange tubes in heat exchanger body 1
11 close to mean temperature, and the shunting effect of heat exchanging device ontology 1 is preferable, exchanges heat more uniform.

The temperature parameter value of 11 inner refrigerants of group carries out regulation inaccuracy to the aperture of regulating valve 2, therefore is not suitable for using above-mentioned controlling party
Refrigerant in method heat exchanging device ontology 1 is adjusted, so after regulating valve runs a period of time with initial opening, air conditioner
Initialization is completed, and air-conditioning system reaches stable state, carries out the aperture adjustment process of above-mentioned regulating valve 2 again later.Furthermore, it is necessary to
It is to be noted that: the setting initial opening of multiple regulating valves 2 can be identical, can also be different.
Optionally, the aperture of the corresponding regulating valve 2 of above-mentioned adjustment specifically includes: the aperture of regulating valve 2 is adjusted to correspondence and is opened
Degree, which is to be determined by experiment the specific aperture of air conditioner regulating valve under different operating conditions, different working condition,
Without being calculated when executing the above method, the aperture after adjusting valve regulation can be obtained by way of tabling look-up；Or it adjusts
Setting aperture is reduced or increased in the aperture of valve 2 on the basis of current aperture, and the variation of each aperture of the latter's regulating valve 2 is all based on
Plus-minus on the basis of current aperture, aperture variation reduce, and system fluctuation reduces, high stability.Wherein, above-mentioned setting is opened
Spend 2% or 5% that △ EVO is the total aperture of regulating valve 2.
Further, setting aperture is reduced or increased on the basis of current aperture and specifically includes for the aperture of regulating valve 2: working as tune
When the sum of current aperture and the setting aperture for saving valve 2 are greater than maximum opening, the aperture of regulating valve 2 is adjusted to maximum opening；Work as tune
When the difference of the current aperture and setting aperture that save valve 2 is less than minimum aperture, regulating valve 2 is adjusted to minimum aperture；When regulating valve 2
Current aperture and the difference of current aperture and setting aperture of setting the sum of aperture or regulating valve 2 be located at maximum opening and most
When between small guide vane, the aperture of regulating valve 2 adjusts working as to the current aperture of regulating valve 2 and setting the sum of aperture or regulating valve 2
The difference of preceding aperture and setting aperture.
