Re: [EnergyPlus_Support] Control Type Objects
I like to think of this in terms of my thermostat at home.
Single Heating: I went to the thermostat at some time in the Fall and
clicked it to heating and set the temperature. This will only give me
heating no matter how hot it gets in the zone there will be no cooling.
Single Cooling: Just like the heating mode above, but for cooling. Not
matter how cold it gets in the zone it will not heat.
Single Heating Cooling: This thermostat has both heating and cooling modes
available, but there is only 1 setpoint available. This could be used in a
system such as the Dual Duct Multizone or a VAV where there is heating and
cooling available and you want to keep 74F in the zone. Part of the time
it could be cooling and other times it could be heating to maintain that
single setpoint.
Dual Setpoint with DeadBand: This should be self-explanatory by
now. There is a heating setpoint and a cooling setpoint and they do not
have to be the same value. They are typically set apart by several degrees.
You need to use either the Single Heating Cooling or the Dual Setpont with
Deadband. Both have heating and cooling available and you have to decide
what scenario you are trying to simulate.
Of course all can be scheduled for different time of the year and if a
person was so inclined they could use and schedule all 4 types in one large
control scenario. I do not know why, but you could.
