There is no difference between Type77 and Type501. The component started out in the TESS Libraries as Type501 but was donated to the standard library and given a new number. It is still in the TESS Libraries for backward compatibility. The thing to remember
about that model is that it is an undisturbed ground temperature model meaning that no matter how much energy you remove from the ground or add to the ground, the ground temperature will only ever be a function of the time of year. If you are using this in
a geothermal application where you are rejecting energy to the ground and removing energy from the ground, the ground temperature will be impacted and you should look at using Type557. If you are drawing air through tubes in the ground then you should look
at using Type460 (Pierre Holmuller's earth duct model as implemented by Transsolar)<br>
<br>
If you aren't able to find data for Type501 then the following will get you started: For the mean soil temperature, use the average annual air temperature for your location. For the amplitude, plot out the monthly average temperature for your location and
calculate the biggest difference between the average annual temperature and the monthly average temperatures. For the time shift, use 30.<br>

<p class="MsoNormal">My project includes a Air treatment unit with a wheel heat exchanger, two fans, and two batteries (warm water and cold water batteries). I get a final regulation system, wich is a ventilating and cooling or heating system (by warm water
and cold water batteries as well), depending on the set temperature. I do understand the system but I don't really know how to modelise it. Is ther any existing type I can use? Should I detail each system like my fans, my batteries...which seems to be complicated.<o:p></o:p></p>
