Manual S, HVAC Equipment Sizing, Cooling, Two Stage and Variable Speed.

Описание к видео Manual S, HVAC Equipment Sizing, Cooling, Two Stage and Variable Speed.

In this video we talk about how to size equipment for two stage and variable speed compressors. ACCA Manual S indicates 0.90 - 1.20 for two stage and 0.90 to 1.30 for variable speed compressors. We also mentioned Heat pumps follow ACCA cooling sizing standard procedure rather than heating.
AHRI conditions are: 95F (DB) / 80F (DB), 67F (WB) which is a correction since in the video we mentioned 90 instead of 95.
