[EnergyPlus_Support] free cooling questions

["olifpp" <olifpp@xxxxxxxxx>]

Hi, all:

      I am doing a simulation of a building which can utilize 
cooling water directly from condenser loop (cooling tower and so 
on).  In this building, there are some larger interior zones which 
also have cooling load on some days in winter, and I think the 
cooling water from the condenser loop is lower in winter and can be 
utilized to substitute the chilled water. 
      The first question is that: how can I get the actual cooling 
load of the interior zones in winter. I have built a purchased air 
model for the building. In the ¡° zone control Thermostatic¡± , I 
used the ¡°single heating setpoint ¡°and¡± the single cooling 
setpoint¡± ,and the ¡°zone control type¡± is ¡°winter 1¡± and 
¡°summer 2¡±. Then I got the result that the cooling load of all the 
interior zones in winter is 0, but actually, it should not be zero. 
How can I get the actual cooling load in winter?
      The second question is : ¡° the free cooler which is set up 
parallelly with the chiller can being open ¡°on¡± in winter. How to 
set the schedule?
   Thanks very much for your suggestion!
