Target exhaust temperature corresponding to rate, as setting target exhaust temperature.Embodiment more preferably sets target exhaust
Temperature Td and compressor real time execution frequency f are linear, are expressed with formula are as follows: Td=m*f+n.Wherein, m and n is known
, the constant being stored in advance.Setting target exhaust temperature, energy are determined according to the linear relationship of compressor real time execution frequency
Enough obtain maximum air-conditioning Energy Efficiency Ratio.
When carrying out PID adjusting control to electric expansion valve using the above method, pass through the frequency in advance running compressor
It is divided into multiple frequency fields, outdoor environment temperature is divided into multiple outer ring temperature areas, and different regions is with corresponding
PID arithmetic parameter value, then locating for real-time frequency region and real-time outdoor environment temperature according to locating for real time execution frequency
Outer ring temperature area selects corresponding real-time PID arithmetic parameter value as the PID arithmetic parameter value in the control of PID tune valve, thus, energy
Suitable PID arithmetic parameter value enough is used for different operating frequency and the operating condition of different outdoor environment temperatures, so that different works
The adjusting of electronic expansion valve opening under condition can reach accurate to greatest extent, stablize, and be conducive to air conditioner coolant under full working scope and follow
The promotion of loop system Energy Efficiency Ratio, and this tune valve method is increased to universal under the air conditioner of different type of machines, different operating conditions
