Thermostatic Valves: Benefits of Pre-Setting

AI Thread Summary
Thermostatic valves with pre-setting in radiator systems offer the advantage of individual temperature control for different spaces. However, a significant drawback is that closing these valves can impact overall flow, necessitating a bypass when flow exceeds 20% of system capacity. This balance between control and flow management is crucial for optimal system performance. Proper installation and adjustment of these valves can enhance energy efficiency. Ultimately, the benefits of personalized comfort must be weighed against potential flow issues.

In a system of radiators, what would be the advantages of having thermostatic valves with pre-setting?
 
Engineering news on Phys.org
One advantage is individual control of space temperature. One drawback is that flow can be effected by the closing of the valves and will need to be bypassed once it exceeds about 20% of the system capacity.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
