The Actual Room Sensible Heat Factor Line Is

Rshf room sensible heat factor.

The actual room sensible heat factor line is. Room sensible heat ratio rshr is the ratio of sensible heat to total heat including latent for a room or zone. The room sensible heat factor rshf expresses the ratio between sensible heat load and total heat load in a room. Rshf c p t r t i h r h i 2. Rshf q sr q tr 1.

The room sensible heat factor line can also be drawn on the psychrometric chart without knowing the condition of supply air. Draw the actual room sensible heat factor line through the room design conditions parallel to the base line in step 1 3 4 fig. Q tr total heat load in room kw btu hr 1 can be modified to. 95 db 75 wb.

The rshrs have all been averaged together for. Effective room sensible heat ersh is the sum of all sensible heat gain that occurs in the room including the gain due to the portion of the ventilation air which is bypassed. Q sr sensible heat load in room kw btu hr. In this scenario a room to room load calculation has been done on a home.

Assuming a room to room load calculation has been done on a building the next step in utilizing the psychrometric chart would be to plot out the room sensible heat ratio lines for each zone. 75 db 50 rh. It can be expressed as. As shown this line may be drawn to the saturation line on the psychrometric chart.
