Dear All I'm simulating a greenhouse using multizone building. Fan and pad is a conventional system in greenhouse. In this method, one of the greenhouse walls is replaced with a wet pad. On the other side there are fans. In order to simulate this method , I need to define we pad as awall in the building. Also the air fans on the other side should be considered. Could anyone guide me how to model it? Inline image 1

Dear all In the fogging device (type 507a) of trnsys, with the outlet air RH humidity controlled, the default value of relative humidity set point is 95. I need a 100% relative humidity for the outlet air. Is it possible to have 100% relative humidity for the outlet air, in practice? Thank you

fan and pad is a common method of cooling in a greenhouse. In this method, one of the walls is replaced with a wet pad, and there are fans on the other side to intake the air. How is it possible to be modeled in trnsys? I have TESS and trnsys16

Dear Mr Hilton Yes I want to use maximum allowable recirculation for saving energy and water. Is there any standard?

I'm going to use a foggig device in an air handling unit to produce humid air for a greenhouse. is a fogging device able to produce fully saturated air at the outlet? If not, what is the maximum possible relative humidity ?

What is the maximum allowable value of recirculation air for a greenhouse?

Hi for an energy wheel of 80 m3/min flow rate at both sides, what is a typican number for sensible and latent effectiveness?

Using multizone building (type 56a) in trnsys16 I'm getting this error. what is the reason?

trying to open a .tpf file of trnsys I'm getting following error. could anyone help me please? The file is created with trnsys 16 and I'm using trnsys 16 also.

Dear All I'm reading about the solid desiccant cooling systems for humid climates. I wonder that most of configurations have the COP lower than 1. For humid climates, another option is to use heat pump to lower the air temperature below the dew point to condense it's moisture and increase this temperature using a heater. Is the COP of such systems lower than desiccant cooling systems? If no , what is the advantage of solid desiccant cooling systems ? Thank you

for the calculation of COP of a solar assisted cooling system, does the energy gain from solar collectors is needed to be used in calculation ? also , in my system there is natural gas , electricity and solar radiation as the input to system, is there any difference between them in calculating the COP or all of the should be used in same manner? Thank you

Using a heat pump for a humid climate like sydney, the air temperature should be lowered below it's dew point , then it should be increased into desired comfort temperature. what is the typical COP of such systems? ( not COP of heat pump alone, I mean the COP of total system including the heater).

I have downloaded the Genopt 2.0.0. I'm going to use Genopt for optimization in TRNSYS.

In the TrnOpt settings, I have used the directory where the GenOpt.class is located. But running the example of optimization, it can not find the genopt program. I have tried it by locating genopt in other drives also, but it doesn't work. Do you have any comment for me ?

The error is :

Genopt could not be found, please check the directory in settings

Helllo in my simulation, when I set the time of simulation at hours 0 to 168 (one week) ,my simulation runs with no problem. But when I set it at 8040 to 8208 (one week), my simulations stops at 70 hours after simulation start. It should be caused by type 109 because when I delete it, my simulation runs with no problem.

This is an error which I get frequently while simulating in TRNSYS. unable to open the file associated with and ASSIGNED logical unit number In this case, the mentioned logical unit is related to evacuated tube solar collector. what is the reason and what should I do?

Thank you for your comment but as you said CVF is no longer distributed and it isn't compatible for windows 7 . My thought is that the errors could be easily solved by editing the properties of dynamic link library but I din't know how I should do it
