I am designing a system using a solar flat plate collector to heat a space. The space is to be heated for use in a solar kiln to dry timber biomass. How do I design for/choose the correct type of heat exchanger? The system will use water or glycol as the heating fluid, and must heat air inside the kiln
first you list the specs needed. Number of joules of heat per hour or day (or calories or BTU), and the temperature range over which it has to operate, and the fluid, and the dimension limitations. And price. Then you search the internet for heat exchangers and compare them to your specs until you find some that match.
