Re: [TRNSYS-users] reg-sizing of coil and cooling load calculation using TYPE 56

Dear S. Rajkumar,
  I would suggest that you start by looking at the restaurant example (..\Trnsys16\Examples\Restaurant\..) as it calculates the heating and cooling load of spaces in a three-zone building. You may have to manipulate the QSENS outputs of Type56 because it reports heating load as a negative value and cooling load as a positive value. You will need to integrate only the positive values to get the annual cooling load and integrate only the negative values to get the annual heating load. As for the peaks, you can report the load for each hour of the year and then find the maximum hourly value using either Type55 or as a post-processing step using Excel to look at an output file.

 One thing to bear in mind though - since TRNSYS uses an annual weather file that contains average conditions, the peak heating and cooling loads are not for design conditions, they tell you only the cooling and heating loads at the worst hour of an average year.

Kind regards,
 David

Dear All,

         I want to calculate  Cooling capacity (  xyz tonnage), cooling peak annual cooling load of simple building in autosize mode using TYPE 56. I could not find such examples in TRNSYS16 latest. I have to do exercise for simple unitary system and building with chiller, cooling tower arrangement.

         I will be grateful, if some one one can help by providing some example.

Thanks and regards
