Where can we discuss fire engineering?
I have some questions on smoke generation and fire growth etc. (BS 7974 related)
Address a problem when it shows up, not when it blows up.
I am doing a project in the GCC - so ambient temperatures are seen as 55°C as per specification document.
So I get the heat rejection from the manufacturer - Q = X kW.
and I want to do a Q= m·c·dT calculation, but I don't know what an acceptable final temperature is for these high ambient...
If I have a heat pump with backup elements, what would be the best (easiest/most reliable) way to control it, so that automatic changeover happens if the heat pump fails?
I thought of just doing it with different setpoints, but the elements will probably then work more than is energy efficient...
Hi
I inherited this project from an engineer who left the firm, so I'm picking it up cold.
A quick overview of the system:
268 bed hostel, 3 storeys. 28000 litre cold water storage tank on third floor, heat pumps on a roof slab, 2x 6000 litre hot water storage tanks in the same plantroom as...
This is my first post to the list.
The system is a 10 m3 container with 1 m3 water and 9m3 steam at 10 MPa.
It is a closed(no mass flows), constant volume system.
If heat is added to this system (say add 1% of current enthalpy), the pressure and the temperature should rise.
My question is...
