3 Terms and Definitions

For the purposes of this document, the following terms and definitions apply.

3.1 electrically driven compressor

motor driven displacement compressor for compressing refrigerant vapour in automobile air conditioning system

Note: it includes compressor with direct current motor and drive controller part. For split-type electrically driven compressor, the above-mentioned two parts are separately installed and applied; for integrated electrically driven compressor, the above-mentioned two parts are integrated into a whole.

3.2 compressor with direct current motor

closed or semi-closed structure consisting of displacement refrigerant compressor and motor

3.3 drive controller

equipment connecting to automobile main power supply controlling energy transmission and conversion between DC power and compressor motor

Note: it consists of external control signal interface circuit, motor control circuit and power driven circuit as well as protective circuit.

3.4 refrigerating capacity

the value obtained through refrigerant mass flow of electrically driven compressor multiplied by the difference between specific enthalpy of refrigerant vapour in thermodynamic state at compressor inlet and that of refrigerant before expansion in the cooling cycle

3.5 heating capacity

the value obtained through refrigerant mass flow of electrically driven compressor multiplied by the difference between specific enthalpy of refrigerant vapour in thermodynamic state at compressor outlet and that of refrigerant before expansion in the cooling cycle

3.6 energy efficiency ratio

ratio of refrigerating (heating) capacity of electrically driven compressor to its input power

3.7 exciting force

periodic simple harmonic vibration force generated by electrically driven compressor rotation unbalanced mass, operation gas pulsation, etc. serving as the vibration source […]
