What is "the simplest HVAC system"? All three (H, V, AC)? Just one? Have you looked at the available "Air Source Heat Pump connected to WCH system"? What is your source / sink?</div><div> </div><div>How is your heat pump connected to the building? Via a/the Ventilation system? Via the WCH? Possibly you can set up a plant that fits your needs with "only" the actual heat pump (between whatever the source/sink is) is missing. Thereby, you can possibly model any effects you need (as "maximum complexity example" maybe look at the exemplar "sports_cen" found in training/chp) and keep post-processing to a minimum.</div><div> </div><div>Best</div><div>Achim</div><div> </div><div> </div><div> <div><div>On Jan 28, 2011, at 8:48 PM, Miguel Silva wrote:</div> <blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div class="hmmessage" style="font-size: 10pt; font-family: Tahoma; "> I've been looking for in plant and not found any component. The system is the simplest HVAC system, the traditional split (heat pump). Since there is no component will have to dothe conversion by the end for each zone. <span class="ecxApple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; font-size: medium; ">Best regards, Thanks Miguel Silva Instituto Politécnico de Leiria - Portugal <hr id="stopSpelling">From: <a href="mailto:achim.geissler@intergga.ch">achim.geissler@intergga.ch</a> Date: Wed, 26 Jan 2011 19:19:55 +0100 To: <a href="mailto:miguelduartefsilva@hotmail.com">miguelduartefsilva@hotmail.com</a> CC: <a href="mailto:esp-r@lists.strath.ac.uk">esp-r@lists.strath.ac.uk</a> Subject: [esp-r] Re: hvac system Dear Miguel<div> </div><div>from what you write, I assume you have a model "up and running" that features "heating and cooling" via simple zone control. In controls, you typically enter the maximum power available (at the receiving end, that is). Simulation results will give you the fraction used at each time step. From this, it should be straightforward to calculated your electricity needs using the COP as a post-process step. No?</div><div> </div><div>There are likely more elaborate approaches available, e.g. via a plant. However, I do not know if there is a plant component available that will exactly fit your needs. Have you looked at plants? There are quite a few exemplars that feature a variety of plant networks.</div><div> </div><div>Best</div><div>Achim</div><div> </div><div> </div><div> </div><div> </div><div> <div><div>On Jan 26, 2011, at 2:41 PM, Miguel Silva wrote:</div> <blockquote><span class="ecxApple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; font-size: medium; "><div class="ecxhmmessage" style="font-size: 10pt; font-family: Tahoma; "> Hi all, <div id="ecxtts_button" class="ecx "> </div>My project has a air conditioning system based on split heat pump. I've walked in to look Esp-r and no find this component. How will I be able to know which energy expended (electric)? In the control module can only put the maximum power heating and cooling and in this case can never put the COP of the machine. someone can help me?
