i) Apparatus Dew Point

ii) Bypass factor
A room has a sensible heat gain of 28 kW and latent heat gain of 7 kW. The
room is maintained at 25°C and 50% relative humidity. 200 m/min of air is
delivered to the room. Calculate RSHF and also determine WBT and relative
humidity of supply air. Indicate the process on a typical psychrometric chart.
What are the modes of thermal interchange between people and environment
Discuss the factors controlling the heat exchange between the individual and
surroundings.
Draw a neat schematic of typical comfort chart representing all relevant
parameters. What do you mean by predicted mean vote (PMV)?
Prepare short notes on any two types of air conditioning control systems with
