VEX320C1 

 Conditions:

- Density = 1.2 kg/m³
- Pressure ratio < 1,11
- other points in acc. with EC327/2011 (see product instructions)

		Capacity curve with Coarse 85% filters (M5)
		SFP curve
		Operating curves
A:		Pressure loss supplement with ePM1 55% filter (F7)
B:		Pressure loss supplement for heating/cooling coil

To calculate capacity data use the product selection tools Quickselect and EXselect.

Total energy consumption is divided equally between the extraction and supply air fans.

Absorbed power with VEX: P₁(W) = SFP (J/m³) x q_v (m³/s).

VEX320C1

	Efficiency with condensation: Extract air = 20°C/55 RH Outdoor air  = -10°C/50 RH Balance between supply air/extract air = 1,0
	Efficiency without condensation with imbalance: Extract air = 25°C/28 RH Outdoor air = 5°C/50 RH Balance between supply air/extract air  = 0,8
	Efficiency without condensation in acc. with EN308: Extract air = 25°C/28 RH Outdoor air = 5°C/50 RH Balance between supply air/extract air = 1,0

Calculation

The temperature efficiency of the VEX units is shown at different airflow ratios, calculated as:

VEX320C1

VEX320C-1 L_WA1 - Suction side
 

VEX320C-1 L_WA2 - Pressure side
 

VEX320C-1 L_WA3 - Surroundings
