Problem

Room components can be added to each room via the Project Tree. These will be added to the default casual gains for the selected room type, as defined in Room Type Manager.

If the gain component is defined incorrectly the following error may occur:

Solution

The "Gains" component shown in the image below allows equipment gains to be added to each room.

The breakdown of latent, radiant and lost heat must then be defined. Information about each of these categories can be found below.

The total sum of these three figures must not exceed 1.

Fraction latent

Used to set the amount of latent heat given off by the equipment component in the room. Fraction latent is a decimal number between 0.0 and 1.0. This number is multiplied by the total power consumed by the equipment component to give the amount of latent energy produced. This energy affects the moisture balance within the room the equipment component is located.

Fraction radiant

Used to set the amount of long-wave radiant heat being given off by the equipment component in the room. Fraction radiant is a decimal number between 0.0 and 1.0. This number is multiplied by the total power consumed by the equipment component to give the amount of long wave length radiation gain from the equipment component.

Fraction lost

Used to set the amount of lost heat being given off by the equipment component in the room. Fraction lost is a decimal number between 0.0 and 1.0. This number multiplied by the total power consumed by the equipment component to give the amount of heat which is lost and does not impact the room energy balances. This might correspond to electrical energy converted to mechanical work or heat that is vented to the atmosphere.
