Count and to adjust the operation of compressor and/or the operation of expansion valve.Thus, it is possible in such as air-conditioner under underload refrigeration mode
Avoid compressor over-heat at the bottom degree not enough during work or even the degree of superheat bigger than normal and lead to air conditioning system to run fluctuation it is also possible to
Such as air-conditioner avoids the occurrence of overload shutdown when working in a heating mode or inner tube temperature, pressure is too high and lead to air-conditioning system
System runs fluctuation such that it is able to air conditioning system effectively being controlled and can optimize with machine system fluctuation and solving reliable
Sex chromosome mosaicism.
Further, since the regulation of the operation of compressor and/or the regulation of the operation of expansion valve can be made to shift to an earlier date in air outlet
Closing or aperture reduction action, therefore even it can be avoided that the fluctuation of short time and further ensure that the stability that whole machine runs
And reliability.
In addition, by experiment, inventor finds to obtain superior system operation using according to the control method of the present invention
Stability (particularly in the case of using preferred preset temperature value as above and preferred regulated value).For example, it is being related to
One of air outlet is closed and air-conditioner is in a certain experiment under heating mode, is not turned off the normal for the moment of air outlet
Operating pressure (pressure at expulsion at exhaust outlet of compressor) is 35.5kgf, after closing one of air outlet, is compensated using adjusting
When overshoot after pressure be 36.5kgf, that is, only exceed 1kgf and keep relatively stable, and be provided without adjusting mistake when compensating
After punching, pressure is then 40.3kgf, that is, exceeds and reach 4.8kgf and cause larger fluctuation.Again for example, it is being related to one of air outlet quilt
Close and air-conditioner is in a certain experiment under underload refrigeration mode, be not turned off air outlet runs the degree of superheat for the moment
(such as compressor over-heat at the bottom degree) is 3.43 degrees Celsius, after closing one of air outlet, using the operation adjusting when compensating
The degree of superheat is 3.5 degrees Celsius, that is, runs that the degree of superheat is basicly stable and meet requirement, and is provided without adjusting operation when compensating
The degree of superheat is then -0.37 degree Celsius, that is, big deviation and lead to not meet requirement.
In addition, the present invention allows multiple difference modifications.
For example, although above-described be frequency-changeable compressor and its operating frequency regulation.However, the present invention can also answer
For other compressor types, such as, there is the invariable frequency compressor of transfiguration function.In such a case, it is possible to be become by regulation
The capacity of positive displacement compressor is come the operation stability of air conditioning system when realizing closing one of air outlet.
Again for example, although above expansion valve work is related to according to the control method of the present invention first illustrative embodiments
The regulation of aperture and be related to the regulation of compressor operating frequency according to the control method of the present invention second illustrative embodiments, so
And the regulation of the regulation of aperture and operating frequency can be compatible it is contemplated that expansion valve works.
