Room Sensible Heat Factor Is Defined As

The supply air having conditions given by any point on this line will satisfy requirements of the room with quantity of air supplied different for different points.

Room sensible heat factor is defined as.

It is defined as the ratio of room sensible heat to room total heat. Kilograms of dry air the basis for all psychrometric calculations. Room sensible heat factor rshf room sensible heat factor rshf is defined as sensible heat load divided by total heat load in a room. Sensible heat factor the ratio of sensible to total heat.

Sensible heat flow sensible heat is dry heat causing change in temperature but not in moisture content. Mitchell paulus 47 982 views. Sensible heat ratio shr is defined as the sensible heat or cooling load divided by the total heat or cooling load. Effective room total heat erth is ersh erlh effective sensible heat factor eshf is the ratio ersh ersh erlh cooling coil in an air conditioning system air.

The following procedure illustrates how to plot this line using the calculated rshf the room design conditions the sensible heat factor scale in the upper right hand corner of the psychrometric chart and the alignment circle at 24 c dry bulb and 50 relative humidity. The percentage of the capacity that goes toward sensible cooling at a given set of conditions for a given piece of equipment or space is called sensible heat ratio shr. Rshf c p t r t i h r h i 2. Sensible heat is the amout of heat absorbed or rejected by a system resulting in the increase or decrease of the temperature of the system.

Effective room latent heat erlh is the sum of all latent heat gain that occurs in the room including the gain due to the portion of the ventilation air which is bypassed. Asked by wiki user. Q sr sensible heat load in room kw btu hr. Consider 1kg of ice at 00 0 degree to be changed to liqiud at 30 degrees.

Remains constant during all psychrometric processes. It can be expressed as. Rshf room sensible heat factor. The room sensible heat factor line can also be drawn on the psychrometric chart without knowing the condition of supply air.

Alignment circle located at 24 c db and 50 rh and used in conjunction with the sensible heat factor to plot the various air conditioning process lines. Q tr total heat load in room kw btu hr 1 can be modified to. This latent heat results only in hase change. The room sensible heat factor rshf expresses the ratio between sensible heat load and total heat load in a room.
