<p class="MsoNormal"><span style="font-size:12pt">I hope all are well. I’d really appreciate it if anyone can help me with the following questions:<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:12pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:12pt">I am using a radiator (Type 1231) for each room to warm up a building (Type 56). First, I determined the maximum loss for this building by choosing a heating setpoint. Then, I chose the maximum heat loss for
each room as the design capacity of the radiator. Does anyone know if I do it correct?<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:12pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:12pt">I chose 55C for the design surface temperature of the radiator. My boiler works at the temperature of 60C. What about the design air temperature? As I know, these values are selected based on the manufacturer
and it is usually 50C less than the mean temperature of the radiator. So, I consider it the predefined value of 10C. Am I correct?
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:12pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:12pt">Also, for the number of pipes, as I understand, it is related to correct the heat transfer to the room and a higher number of pipes results in a lower heat transferred to the room. Does anyone know if it
is exactly equal to the number of water channels insider the radiator? If yes, so, It should be related to the length of the radiator and so a higher number should be selected for a radiator with a higher capacity.<u></u><u></u></span></p>
