HVAC System Design- Formulae
I have been approached by lot of people to teach them system design for the HVAC&R product development and I thought it fit for them to start from basics as without solid foundation there can be no building.So I thought of compiling the basic formulae first and then go for the system design aspects.It has taken me considerable time to compile these formulae. I would like to thank Ms. Ashima Saxena for helping me in editing the list of the compilation.
