Obtaining compressor reduces the frequency for being less than or equal to compressor when being unsatisfactory for default ability value interval limit after frequency, then is considered as sky
Adjusting power is less than or equal to the predetermined power upper limit；If air-conditioning work ability is more than or equal to the lower limit in default ability value section, and empty
Adjusting power is less than or equal to the predetermined power upper limit, then keeps suction superheat to be in default suction superheat section, it is swollen to adjust electronics
The aperture of swollen valve records the air-conditioning work ability and Energy Efficiency Ratio combination of preset quantity, from each group air-conditioning work ability and Energy Efficiency Ratio
Optimum combination is screened in combination, and judges whether the air-conditioning work ability in optimal air-conditioning work ability and Energy Efficiency Ratio combination reaches
Default ability value interval limit adopts opening for electric expansion valve if air-conditioning work ability is less than default ability value interval limit
Degree, increases the frequency of compressor, can be calculated and be compressed according to the difference of air-conditioning work ability value and default ability value interval limit
Machine needs raised frequency；If air-conditioning work ability is more than or equal to default ability value interval limit, air-conditioning power is judged again
It whether is more than the predetermined power upper limit, if air-conditioning power adopts optimal air-conditioning work ability and efficiency greater than the predetermined power upper limit
Than the aperture for combining corresponding electric expansion valve, the frequency of compressor is reduced, it can be according to air-conditioning power and the predetermined power upper limit
Difference calculate compressor and need reduced frequency, be less than or equal to after compressor, which is calculated, reduces frequency and be unsatisfactory for presetting
The frequency of compressor when ability value interval limit, then directly output air conditioning performance matches deficiency report；If air-conditioning work energy
Power is more than or equal to default ability value interval limit, and air-conditioning power is less than or equal to the predetermined power upper limit, then will in such cases
Air-conditioning work parameter is determined as effective running parameter, and then can generate APF according to effective running parameter and corresponding Energy Efficiency Ratio
It calculates and reports and export.
The technical solution of the present embodiment obtains the relevant parameter of operation of air conditioner according to national standard enthalpy difference experiment platform, corresponding to adjust
The frequency of compressor and the aperture of electric expansion valve, determine effective running parameter, and output APF report guidance technology personnel carry out empty
Adjust Performance Match work.
