This latent heat results only in hase change.

Effective room sensible heat factor.

It can be expressed as. Effective room latent heat load erlh rlh bpf x outside air lh. Rshf c p t r t i h r h i 2. Q sr sensible heat load in room kw btu hr.

This equation is not strictly correct because the by pass factor should be applied to the gth line. Sensible heat ratio shr factor shf. Effective room sensible heat room sensible heat supply duct sensible heat portion of outdoor air bypassed through the apparatus. Prashant anand ranjan 513 views.

The bpf fraction of outside air adds sh load and lh load to the room. However bpf fraction of return air has no effect as it is already at room condition. Q tr total heat load in room kw btu hr 1 can be modified to. Effective room sensible heat room sensible heat supply duct sensible heat portion of outdoor air bypassed through the apparatus.

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. Room sensible heat factor rshf room sensible heat factor rshf is defined as sensible heat load divided by total heat load in a room. There is another heat factor called the latent heat. 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 gets cooled when it passes through the cooling coil.

Rshf room sensible heat factor. An additional 5 on rsh is taken as a safety factor and this also covers items such as heat gain by the supply duct leaks etc effective room sensible heat gain a 1 solar gain glass a 2 solar transmission gain through the walls and roof a 3 transmission gain through the walls and partitions a 4 heat gain 1 through. Consider 1kg of ice at 00 0 degree to be changed to liqiud at 30 degrees.
