VPR 120

VPR 120 is a ventilation unit with heat recovery via a rotary exchanger in combination with a heat pump. The heat pump has a reversible cooling circuit and it can cool or heat supply air according to requirement. 

The unit achieves a very high cooling and heating effect and therefore also a good COP. This is due to the rotary exchanger in combination with optimal positioning of condenser and evaporator. The variable speed drive compressor of the unit enables precise regulation of the supply air temperature. 

VPR 120 is often used in buildings with cooling requirements, such as office buildings, retail premises, concert halls etc.

Capacity (condensation exchanger)

The following design data is calculated on the basis of a condensation exchanger.

Max Pa capacity of standard unit, Pt,ext as a function of qv, with regard to SFP-values.

SFP-values according to EN13053 for a standard unit with ISO ePM10 >60% (M5) & ISO ePM1 50% (F7) filters an no heating element.

* Airflow speed above evaporator is measured at meters per second.

Attention! The SFP values are measured and stated as a total value for both fans.

Heating data (condensation exchanger)

The following design data is calculated on the basis of a condensation exchanger.


Heating data are calculated with the following temperatures:
Outdoor temperature: -7 ° C
Indoor temperature: 20 ° C
 

Capacity (sorption exchanger)

The following design data is calculated on the basis of a sorption exchanger.

Max Pa capacity of standard unit, Pt,ext as a function of qv, with regard to SFP-values.

SFP-values according to EN1353 for a standard unit with ISO ePM10 >60% (M5) & ISO ePM1 50% (F7) filters and no heating element.

* Airflow speed above evaporator is measured at meters per second.

Attention! The SFP values are measured and stated as a total value for both fans.

Cooling data (sorption exchanger)

The following design data is calculated on the basis of a sorption exchanger.


Cooling data are calculated with the following temperatures:
Outdoor temperature: 35 ° C
Indoor temperature: 27 ° C
 

Temperature efficiency

Temperture efficiendy for rotatry heat exchanger according to EN308 (dry).

Sound data

Sound data for qV = 1200 m3/h and Pt, ext = 250 Pa according to EN 9614-2 for surfaces and EN 5136 for ducts.

Sound output level LWA drops with falling air volume and falling back pressure.

Sound output level LpA at a given distance will depend on acoustic conditions in the place of installation.

The CTS602 control system is an advanced control system with many settings options. The control system is supplied with factory default settings that can be adapted to the operational requirements in order to achieve best possible operation and utilisation of the unit.

The HMI Touch panel provides an overview of the current operation of the unit, and the structure of its menu makes it easy to navigate for both user and installer. There is an option for selecting between 2 front page images for the main screen.

External communication

The CTS602i control unit communicates by default with Modbus RTU RS485 communication. A CTS system using this form of communication can easily be connected to the unit.

Functions overview   +Standard
-Accessories
Alarms Description of errors indicated with alarms. Alarm log displaying the latest 16 alarms. +
Joint alarm The CTS602 control system has an output signal that is activated in the case of an alarm. It can be connected to, for example, external automation.  
Filter monitor Filter alarm with timer that can be set to 30/90/180/360 days. +
Data display An overview of the current operation with regards to temperatures, fan speed level etc. +
Week program The CTS602 control system has 3 week programs that can be set individually (the default setting is “off”). +
Humidity control Enables a higher or lower degree of ventilation at a high/low level of humidity. -
Air quality Enables you to adjust the degree of ventilation depending on the CO2 level in the air. -
Winter low You can prevent a low level of humidity in the dwelling by activating low ventilation at low outdoor temperatures. +
Temperature regulation Enables you to control the operation of the unit in accordance with the room temperature. +
Summer/winter mode You can set the unit to operate in summer or winter mode.
