The indicated latent part of the cooling load refers to the same point in time, so it is not the largest latent cooling load ever occurring. It should be noted that if the system capacity is limited, it is assumed that a central system is used, which can supply the rooms as required. The operating hours indicate how long the heating or cooling runs.
The energy balance indicates how the yearly heat inflow and outflow are made up.
For rooms, the over- and undertemperatures excess/under temperatures are displayed. They indicate the deviation of the perceived The maximum temperature overrun/undercut is the largest deviation of the operative temperature when people are present.
The degree hours are the sum of the hourly deviations of the operative temperature from the setpoint band. The traffic time is the number of hours per year during which people are in the room.The over/undertemperature hours indicate the number of hours in which the target value was exceeded or undercut by at least 0.5°C. The over/undertemperature degree hours are the yearly sum of the exact deviations. The frequency is calculated from the temperature hours and the traffic time, the average deviation from the temperature hours and the degree hours, counting only hours when people are present. It should be noted that heating and cooling are controlled by air temperature, so deviations in perceived temperature will occur even when setpoints are maintained.
The excess/under temperature hours are the number of hours that the air temperature exceeds or falls below the set point. The hours of occupancy are the number of hours per year that people are in the room.
Zones, floors and the building have no temperatures of their own and therefore no over- and undertemperatures. Instead, the distribution of loads to the contained rooms is displayed. The desired load can be selected. Internal heat sources are people, equipment and lighting. For ventilation and transmission the sum of inflow and outflow is used.
