<p class="MsoNormal">Hey Guys!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I was just removing the Unmet hours from my Proposed and Baseline Models and have encountered a few questions.<o:p></o:p></p>
<p class="MsoNormal">It would be really nice if you could let me know the correct approach!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b><u>Proposed Case<o:p></o:p></u></b></p>
<p class="MsoNormal">- As the Proposed building has District Heating (hot water via Steam Meter) there are a lot of Unmet hours (approx. 5000)<o:p></o:p></p>
<p class="MsoNormal">- To design the radiators I've use Baseboard heating with Control as Thermostatic.<o:p></o:p></p>
<p class="MsoNormal">- Increased the Min Air flow ratio in the Zones of the VAV system to almost 0.9<o:p></o:p></p>
<p class="MsoNormal">- Increased Throttling range to 5°R<o:p></o:p></p>
<p class="MsoNormal">- Increased Reheat Delta T to 35°F<o:p></o:p></p>
<p class="MsoNormal">There is no restrain on the amount of heat the building wants.<br>
Hence, I wish the building receives unlimited heating from the Hot Water(Purchased Heat),So whatever is the requirement ,it is sufficed by the Heating system.<br>
This may lead to reduction in Heating Unmet hours.<o:p></o:p></p>
<p class="MsoNormal">1)How can I do this, to reduce the Heating Unmet hours?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b><u>Baseline Case : System 7<o:p></o:p></u></b></p>
<p class="MsoNormal">- As the VAV system is with Reheat, and the heating is through Hot water(Purchased heat).<o:p></o:p></p>
<p class="MsoNormal">1)Would it be right to Keep Baseboard Heating using Hot water on to counter Unmet hours?<o:p></o:p></p>
<p class="MsoNormal">Unmet hours is Approx 5000.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">- As per G3.1.3.12, The Min Air Flow ratio is to be 0.4<o:p></o:p></p>
<p class="MsoNormal">2)Can I increase it to counter Unmet Cooling and Heating hours?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As the Project Deadline is <b>28/10/16</b>. I really needed advice.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please Feel Free to add any suggestion or approach strategies! :)<o:p></o:p></p>
