<p>Dear all,</p>
<p> Happy new year!</p>
<p> I have a question about calculating total heating demand:</p>
<p>There is one same room to keep indoor temperature as 20°C one day 24 hours, the initial indoor temperature is 20°C, there is no infiltration no other internal gains in the room. I used 3 different methods to calculate total heating demand of one day, separately.</p>
<p>1.First is heating in TRNBuild: after using the INTEGRATOR TYPE 46, the QHEAT is about 34314 kJ.</p>
<p>2.Second is floor heating(active layer): after using the INTEGRATOR TYPE 46, the QALFL_Inlet is about 33680.7kJ.</p>
<p>3.Third is still floor heating(active layer): after using the INTEGRATOR TYPE 46, but I used Q=CwaterMwater(Tinlet-Toutlet), the result of Q is 144639kJ.</p>
<p>My question is: 1) To 2 and 3: Why is the difference is so large? 3 is almost 4 times than 3? I will get the total heating demand, which one is right? Why? What's different of both of them?</p>
<p>2) If 3 is right. Generally, the floor heating should be more energy-saving than common heating. But here result is absolutely opposite. The common heating is more energy-heating. Why? Here what difference of common heating and floor heating?</p>
<p>Many thanks!</p>
<p>Br.</p>

<div bgcolor="#ffffff" text="#000000">Hongbo,<br> YCHECK and OCHECK are arrays that carry three letter codes for the units (C, kg/h, etc.) of a Type's inputs and outputs. The code "TE1" for example, means "temperature in degrees C." Each component passes the codes for its inputs and outputs to RCHECK and RCHECK looks to make sure that you do not have any inconsistent connections made in the input file (such as connecting a mass flow rate output to a temperature input). There are features in the Trnsys Studio that perform similar checks as well. I had a look at the Type564.for code and I do not see why it would generate an access violation as you describe. I would recommend that you send the project you are trying to run as well as your Type564 code to your distributor to see if they can help you. I would not recommend simply deleting the call to RCHECK since the access violation error is a good indication that there is a real problem somewhere.<br>
Kind regards,<br> David<br><br>On 1/8/2011 18:17, He Hongbo wrote:
<blockquote type="cite">Hi,<br><br>I found the problem about the code type564.for. In the code DATA STATEMENT part, if we delete the "CALL RCHECK(INFO,YCHECK,OCHECK)", then it works well. Or else we will get the error message "Access violation at address 10037D25 in module 'TRNDLL.DLL'. Read of address 00000003." In the TRNSYS manual chapter 8 8.3.5, an example code about how to create a new component does not include "CALL RCHECK(INFO,YCHECK,OCHECK)" in the DATA STATEMENT part. What is the function of RCHECK?<br>
<br>Thank you so much<br> <br>Best Regards!!<br><pre><fieldset></fieldset>

<div bgcolor="#ffffff" text="#000000">David<br>If you are using Trnsys17 and standard format weather files such as *.tmy, *.tm2, *.epw, *.tm3 then I would recommend using Type15 for your weather processing. If you are using Trnsys16 and a standard format weather file then you need to use Type89 in combination with Type16. Type9 is intended to read non-standard format data files and from your description of the weather files that you have, it sounds as though you will need to use Type9. If you have the *.xls version, I would recommend that you save that file as a "comma separated value" file (*.csv) and then read it with Type9. One of Type9's parameters asks you how many header lines there are before the data begins. Another parameter asks you how many values to read. This second parameter corresponds to the number of columns that are in your *.xls file.<br>
