VTS VENTUS PRO PVS PO 25 EC [10/25] Control panel

VTS VENTUS PRO PVS 18x18 [10/25] Control panel

Design and application

» Recuperator made of crosswise stamped aluminum plates, between which

supply and exhaust air passes alternately in counterow arrangement.

» As standard, the recuperator is equipped with by-pass damper, enabling its

securing against frosting and heat recovery capacity regulation.

» The recuperator provides sensible heat recovery for warmer air to the colder one.

For winter season – recovery of heat from return air to supply.

For summer – recovery of chill from return air to supply.

Specication

» Energy recovery with very high separation of supply and exhaust air streams (99.9%).

» Heat recovery with temperature efciency up to 76% depending on the amount

of air owing through it

» Plates can be epoxy coated or made of stainless steel.

» It can work in the range from -30°C to 90°C.

» The exchanger is equipped with a condensate pan, which is made of stainless steel

PLATE CROSS-FLOW EXCHANGER

Design and application

» Set of two water coils – one in supply, the other one in exhaust airstream.

» The coil in return airstream recovers the heat (cooler) and passes it to the coil

in the supply air (heater) by means of heat-transfer uid (water-glycol mixture).

In case of chill recovery, entire process is reversed.

» System applied for supply and exhaust air handling units installed remotely

to each other.

» There is a circulation pump and balance tank in the circuit. A stainless double

inclined condensation pan is used on theexhaust side.

Specication

» Indirect Energy recovery (sensible heat) at 100% supply and exhaust airstreams

separation.

» Max heat-transfer uid operation pressure: 1,6 MPa=16 bar (tested 21 bar).

» Max glycol concentration: 50%.

Design and application

» Two exchangers (evaporator and condenser) connected in one closed

thermodynamic system lled with refrigerant. One exchanger on the fresh air

side and the other on the exhaust air side.

» A device uses a two-phase, closed cycle to transfer heat, with the evaporation

of the working uid in the evaporator and its subsequent condensation in the

condenser.

» The heat pipe is a very efcient passive device used to transfer energy. Heat pipes

let high efcient transfer at minimum temperature differences, simple structure,

and easy control, and no required moving parts like a pump or compressor.

» A heat pipe heat exchanger is utilized as an efcient air-to-air heat recovery

device in both commercial and industrial applications.

Specication

» Efciency is between 40-60%.

» Closed loop system

» Unidirectional winter or summer recovery.

CONTROL PANEL

Technical Specification

2120

Components

» Both: the MCC (Micro Control Center) power panel and the DDC (Direct Digital Controller) power

supply and control panel are offered.

» The panel can be built into the AHU also as Plug & Play version (MCC & DDC) or delivered as an

external power supply or power supply and control switchboard.

» General control - temperature and humidity control for simple applications. It includes: an electronic

control panel, duct temperature and humidity sensors, valve actuators, and damper actuators.

Frequency converters (AC motors) can be added if required.

» Precise control - an advanced microprocessor control system with software specially designed

for the needs is used. Flow rate, temperature, humidity, lter contamination, pressure difference

between spaces, etc. The location and device information can be controlled by a microprocessor.

» The control system can be integrated with the building management system (BMS).

THE CONTROL SYSTEM CAN MANAGE THE FOLLOWING FUNCTIONS

» Automatic selection of cooling and heating.

» Humidity control (humidity, enthalpy).

» Comfort enhancement or dehumidication control with the after heater.

» The desired air ow can be adjusted according to the operating altitude and temperature.

» Adjusting the aspirator ow according to the actual fan ow rate at the desired positive or negative pressure

ratio.

» Cleaning mode input on the controller that automatically increases the ow for fast cleaning of the room.

» Programming of seven days of the week with 4 different daily programs (temperature, ow rate, on-off).

» Daily, weekly work-stop time can be adjusted.

» Flow temperature limit control (comfort temperature, condensation start temperature).

» It can be integrated into the building automation system with all known communication languages

(Modbus, BACnet, Lon-ECHELON, LAN TCP / IP, SNMP) with an additional hardware.

» All similar devices can be communicated as a network.

» The control of the fans can be done parametrically, thermostatic, continuously, gradually or proportionally.
