I thought that there is a solar panel on the roof of the house and it makes hot water to be used in bathroom and kitchen and when there is not enough solar radiation hot water is made by electric energy or a boiler using naturel gas. is it possible for me to convert this model into such a model? </span></div><div id="yui_3_16_0_1_1430380097051_30420"><span id="yui_3_16_0_1_1430380097051_30419"></span> </div><div id="yui_3_16_0_1_1430380097051_30422"><span id="yui_3_16_0_1_1430380097051_30421">I simulated the model for february and listed the data of sensible heating load in result analysis modul. many of the zones heating load is zero but few zones have heating load in some hour. does it mean that the solar panel is not enough at that times to keep the zone at 22 oC?</span></div><div id="yui_3_16_0_1_1430380097051_30435"><span></span> </div><div id="yui_3_16_0_1_1430380097051_30852"><span id="yui_3_16_0_1_1430380097051_30872">Thank you</span></div><div id="yui_3_16_0_1_1430380097051_30853"><span></span> </div><div id="yui_3_16_0_1_1430380097051_30433"><span id="yui_3_16_0_1_1430380097051_30871">Best</span></div><div id="yui_3_16_0_1_1430380097051_30432"><span>Gul</span></div><div id="yui_3_16_0_1_1430380097051_30431"><span></span> </div><div id="yui_3_16_0_1_1430380097051_30430"><span></span> </div><div id="yui_3_16_0_1_1430380097051_27517"><span></span> </div><div id="yui_3_16_0_1_1430380097051_27104"><span></span> </div><div id="yui_3_16_0_1_1430380097051_19244"><span></span> </div> <br><div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"> <font face="Arial" size="2"> 29 Nis 2015 15:37 Çarşamba tarihinde Jon Hand <jon@esru.strath.ac.uk> şöyle yazdı:<br> </font> </div> <br><br> <div class="y_msg_container"><br clear="none">Some answers to your questions....<br clear="none"><br clear="none">1) the model has no back-up heating - it relies totally on solar gains. If you want<br clear="none">the top of the tank to be maintained at a higher temperature you could use an<br clear="none">ideal control law to inject heat into the top tank zone (sense the temperature in<br clear="none">the top of the tank and actuate in that same zone). In the results analysis you<br clear="none">could then see how much heat had to be added to maintain the temperatures.<br clear="none">Assuming electrical resistance heating the reported heat injection value would be equal to<br clear="none">the electrical power.<br clear="none"><br clear="none">2) I did not include any description of using hot water for people. I have not tested<br clear="none">if it is possible to get water from the tank. What temperature would the mains<br clear="none">water arrive at?.<br clear="none"><br clear="none">3) how much water would be required and when would it be required? ESP-r<br clear="none">needs someone to define how much, what rate of flow in a schedule. Some<br clear="none">tests would be needed.<br clear="none"><br clear="none">-Regards, Jon<br clear="none"><br clear="none">________________________________________<div class="yqt7469054743" id="yqtfd12201"><br clear="none">From: <a href="mailto:esp-r-bounces@lists.strath.ac.uk" shape="rect" ymailto="mailto:esp-r-bounces@lists.strath.ac.uk">esp-r-bounces@lists.strath.ac.uk</a> [<a href="mailto:esp-r-bounces@lists.strath.ac.uk" shape="rect" ymailto="mailto:esp-r-bounces@lists.strath.ac.uk">esp-r-bounces@lists.strath.ac.uk</a>] on behalf of Gül Nihal Güğül [<a href="mailto:gulgugul@yahoo.com.tr" shape="rect" ymailto="mailto:gulgugul@yahoo.com.tr">gulgugul@yahoo.com.tr</a>]<br clear="none">Sent: 29 April 2015 11:51<br clear="none">To: <a href="mailto:esp-r@lists.strath.ac.uk" shape="rect" ymailto="mailto:esp-r@lists.strath.ac.uk">esp-r@lists.strath.ac.uk</a><br clear="none">Subject: [esp-r] cellular_expl_sdhw<br clear="none"><br clear="none">Hi all,<br clear="none"><br clear="none">I am working on cellular_expl_sdhw model.
