<div>Dear Mr. doell,</div>
<div> </div>
<div> Many thanks for your reply!</div>
<div> </div>
<div> 1. To case 2 and 3: I tried a larger time period 10 days. But the result is still that case 3 is about 4 times than case 2. Do you mean I should simulate one month or one year?</div>
<div> </div>
<div> 2. You're right, I didn't simulate any heat generation. Do you mean I should add the boiler into Active Layer(floor heating). If so, how to add the boiler into the Active Layer? Which type need i use?</div>
<div> </div>
<div>3. you mean Qheat is the case 1's real heat demand. Is the QALFL_Inlet of case 2 not the real heat demand? Is it samller than the real total heat demand? If so, how to get the real total heat demand of case 2 and 3?</div>
<div> </div>
<div>Many thanks!</div>

Date: Fri, 07 Jan 2011 11:07:42 +0100<br>Subject: Re: [TRNSYS-users] Total heating demand (??)<br>Dear Wang,<br><br>Regarding your first question: I suspect the thermal capacity of the floor to cause the difference between case 2 and 3. Simulate a larger time period and this effect should get smaller.<br>
<br>About your second question, floor or wall heating systems are more efficient than radiator based heating systems because they demand lower inlet (or forward) temperatures. By this boiler (and potential storage) efficiency increases. Since you do not simulate any heat generation, these effects do not occur in your simulation.<br>
I expect the Qheat of case 1 to be the real heat demand and QALFL_Inlet of case 2 to be the heat delivered to the room by the active layer.<br><br>Hope this helps.<br><br>Best regards,<br>Jochen<br><br><br><a href="mailto:trnsys-users-request@cae.wisc.edu" target="_blank">trnsys-users-request@cae.wisc.edu</a> schrieb:<br>

<br><br>Dear Matt and Salim,<br><br><br>One example of usage for "wall gain" is when you have defined a boundary<br>wall with known boundary temperature, but also want to take into account<br>solar gain from windows on that wall. You can not (at least in TRNSYS 16)<br>
define windows in the normal manner on boundary walls. For example, if you<br>are modelling a zone adjacent to a highly glazed building with known<br>temperature, and a glass wall separates the two. Then you can use "wall<br>
gain" to impose the solar heat flux from the adjacent building on the<br>boundary wall.<br><br><br>Best regards,<br><br>Knut Erik Enerstvedt<br><br><br><br> <br>

Date: Thu, 06 Jan 2011 15:17:53 -0200<br>Subject: [TRNSYS-users] Type 927 (Water to Water Heat Pump)<br>Hello,<br><br>I am simulating a DHW-System where the heat is provided by a flat plate solar collector. Between the collector circle and the water tank circle I have put in a water-to-water heat pump (Type 927). The main idea behind this is to replace the auxiliary heater of the water tank. Sadly the heat pump doesn’t work right:<br>
<br>The plotter shows a value of nearly zero for the gain heat of the collector and the heat transfer to the load circle of the heat pump is lower than the supplied power to the pump. But for me the heat pump shall follow this equation: Heat_source (=Heat_coll) + Power_pump = Heat_load.<br>
<br>A further question is: is it allowed to change the temprature and mass flow values in the performance data files of the heat pump?<br><br>For a better understanding I have attached the working file.<br><br>Thank you very much for any kind of help in advance.<br>
<br>With best regards,<br><br>Andrey<br><br><br>_______________________________________________<br>TRNSYS-users mailing list<br><a href="mailto:TRNSYS-users@cae.wisc.edu">TRNSYS-users@cae.wisc.edu</a><br><a href="https://mailman.cae.wisc.edu/listinfo/trnsys-users" target="_blank">https://mailman.cae.wisc.edu/listinfo/trnsys-users</a><br>
