[esp-r] Re: Dissatisfied wall rad. temp. assymetry

[Jon Hand]

A question about MRT sensors....

The statment includes 'my sensor is facing north'.  A MRT sensor is a rectangular body
and all faces have the same properties and so this phrase is confusing. How does
one face a rectangular body away from the window?  Or is it that the sensors which
are farther from the window that are giving a different than expected prediction?

Subject: [esp-r]  Dissatisfied wall rad. temp. assymetry

Dear group,

I am doing an dynamic analysis on discomfort on MRT and VRT with different types of panes where some has build-in PV-cells.

My model has a south facing window and 4 radiant sensors placed in different distances from the window.

The results from my simulation shows that the maximum percentage of dissatisfied with wall rad. temp. assymetry is larger when my sensor is facing north (away from the window) than when the sensor is facing the window. I would assume that the percentage of dissatisfied (VRT) would be the same regardless if the sensor is facing north or south.

Can anyone explain the procedure here?

Any input is appreciated :)
