### Normal year temperature

Median annual temperature at the current location. That is, at what temperature the same number of days is warmer and colder.

### Supply air temperature

The temperature of the air that is blown into the room through the ventilation.

### Extract air temperature

The temperature of the air leaving the room.

### Flow

The flow on which the energy demand is to be calculated.

### Heat recovery rate

Refers to the efficiency of recycling in the air handling unit.

### Operating time

Avser hur många timmar per dag och dagar i veckan som luftbehandlingsaggregatet går.

### Heating energy

Determines how many hours per day and days of the week the air handling unit goes.

### Cooling energy

The energy that goes into cooling the outdoor air to the desired supply air temperature for one year.
