3 Terminologies and definitions
Terminologies and definitions established in GB/T 16803 and the following terminologies and definitions are applicable to this standard.
3.1 Air to air energy recovery equipment
Equipment combination with energy recovery core is the kernel and realizes air draft energy recovery by ventilation and air change; it is called equipment for short. Equipment includes two types: with blower fan and without blower fan.
3.2 Total heat exchange equipment
Fresh air and exhaust air generate sensible heat and latent heat exchange equipment simultaneously.
3.3 Sensible heat exchange equipment
Fresh air and exhaust air generate only sensible heat exchange equipment.
