1. the efficiency computational methods of a kind of air conditioner, it is characterised in that comprise the following steps:

  • Current working, the power and air conditioner power consumption of compressor of air conditioner are obtained, and obtains the height of exhaust outlet of compressorPress lateral pressure;

    Obtain the gas returning port temperature t of gas returning port in compressor1, in the compressor exhaust outlet exhaust port temperatures t2, outdoor heat exchangeThe outdoor heat exchanger first end temperature t of device first end4, indoor heat exchanger first end indoor heat exchanger first end temperature t7And pressureThe tonifying Qi temperature t of contracting machine tonifying Qi entrance8

    When the current working of the air conditioner is cooling condition, according to the gas returning port temperature t of gas returning port in the compressor1It is rawInto the refrigerant enthalpy h of gas returning port1 refrigerantWith lubricating oil enthalpy h1 lubricating oil, according to the exhaust port temperatures of exhaust outlet in the compressort2With the refrigerant enthalpy h of high side pressure generation exhaust outlet2 refrigerantsWith lubricating oil enthalpy h2 lubricating oil, changed according to the outdoorThe outdoor heat exchanger first end temperature t of hot device first end4Generate the refrigerant enthalpy h of outdoor heat exchanger first end4 refrigerantsAnd lubricationOily enthalpy h4 lubricating oil, according to the indoor heat exchanger first end temperature t of the indoor heat exchanger first end7Generate indoor heat exchanger firstThe refrigerant enthalpy h at end7 refrigerantsWith lubricating oil enthalpy h7 lubricating oilWith the tonifying Qi temperature t according to the compressor tonifying Qi entrance8Generation is mendedEnter the gaseous refrigerant enthalpy h of compressor8 '"'"' refrigerantsWith lubricating oil enthalpy h8 '"'"' lubricating oil, flash vessel liquid refrigerant enthalpy h8 " refrigerantsWithLubricating oil enthalpy h8 " lubricating oil

    According to the refrigerant enthalpy h of the gas returning port1 refrigerantWith lubricating oil enthalpy h1 lubricating oilGenerate the mixture enthalpy h of gas returning port1,According to the refrigerant enthalpy h of the exhaust outlet2 refrigerantsWith lubricating oil enthalpy h2 lubricating oilGenerate the mixture enthalpy h of exhaust outlet2, according toThe refrigerant enthalpy h of the outdoor heat exchanger first end4 refrigerantsWith lubricating oil enthalpy h4 lubricating oilGenerate the mixed of outdoor heat exchanger first endCompound enthalpy h4, according to the refrigerant enthalpy t of the indoor heat exchanger first end7 refrigerantsWith lubricating oil enthalpy h7 lubricating oilGeneration is indoorThe mixture enthalpy h of heat exchanger first end7, according to the gaseous refrigerant enthalpy h for filling into compressor8 '"'"' refrigerantsWith lubricating oil enthalpyValue h8 '"'"' lubricating oilGeneration fills into compressor mixture enthalpy h8’

    , according to the liquid refrigerant enthalpy h of the flash vessel8 " refrigerantsAnd lubricationOily enthalpy h8 " lubricating oilGenerate the mixture enthalpy h of flash vessel8”



    According to the power of the compressor, the mixture enthalpy h of the gas returning port1, the exhaust outlet mixture enthalpy h2, instituteState the mixture enthalpy h of outdoor heat exchanger first end4, the indoor heat exchanger first end mixture enthalpy h7, described fill into pressureContracting machine mixture enthalpy h8’

    With the mixture enthalpy h of the flash vessel8”

    Generate the refrigerating capacity of air conditioner;

    AndThe efficiency of the air conditioner is generated according to the air conditioner power consumption and the refrigerating capacity.
