Description
DESCRIPTION CASING
  • The AVU 03 air handling unit is a fully-featured ventilation unit that ensures air filtration, fresh air supply and stale air extract.
  • Extract air heat energy is recovered by a rotary regenerator.
  • The unit is applied as component of ventilation and air conditioning networks for various premises requiring cost-efficient controllable ventilation.
  • Integrated EC motors provide energy demand decrease by 1.5 to 3 times and ensure low noise level.
  • The AVU air handling unit series is expected to be supplemented with AVU 05, AVU 07, AVU 09, AVU 11 and AVU 14 models with air capacity up to 14 000 m3/h.
  • The casing is made of sandwich panels, 25 mm thick for inner modifications and 50 mm thick for outer modifications.
  • The aluzink panels are filled with mineral wool between for reliable sound- and heat insulation.
  • Specially designed swivel side panels of the unit ensure easy access to the unit components and enable the unit mounting in limited service space conditions.
  • The supply and exhaust air ducts are fitted with electrically actuated air dampers.
  • The outer models are equipped with protecting hoods for fresh air intake and stale air exhaust.
MODIFICATIONS FILTERS
  • AVU 03/SE/R – inner modification model.
  • AVU 03/SE/R/H – inner modification model, water heater.
  • AVU 03/SE/R/О – outer modification model.
  • AVU 03/SE/R/ОH – outer modification model, water heater.
  • The unit has two filters, a G4 panel filter and a F7 bag filter.
  • Extract air is purified with a G4 panel filter.
ROTARY REGENERATOR
MOTOR
  • High-efficient electronically-commutated direct current motors with external motor and impeller with backward curved blades.
  • Such motors are the most state-of-the-art energy-saving solution.
  • EC motors are featured with high performance and total speed controllable range.
  • High efficiency reaching 90% is the premium advantage of the electronicallycommutated motors.

Rotary regenerator operating logic
HEATER CONTROL AND AUTOMATION
  • The unit AVU 03/...H is equipped with a water heater for the unit operating conditions at low outside temperatures.
  • If set supply air temperature is not be attained with heat recovery only, the heater is turned on to warm up air flow supplied to the room.
  • The water heater is compatible with the systems with maximum operating pressure 1.0 Mpa (10 bar) and maximum heat medium temperature + 95 °С.
  • The unit is equipped with integrated automation.
AUTOMATION FUNCTIONS:
  • turning the unit on/off according to set control logic;
  • setting supply air temperature and air flow from the remote control panel;
  • actuating air dampers;
  • filter control with a differential pressure switch;
  • supply and control and regulation by actuating the heat medium regulating three-way valve;
  • circulation pump control and regulation;
  • water heater freezing protection by the temperature sensor downstream of the water heater and the return medium thermostat.
COOLER  
  • The unit has connection possibilities for a water cooling block (C3 / AVU 03, special accessory) or DX cooling block (DX3 / AVU 03, special accessory).
  • These blocks are available in outer and inner modifications with a panel width 50 or 25 mm respectively.
MOUNTING
 
  • The unit is designed for mounting on a horizontal surface. Access for servicing through side panels.

Water heater parameters:


Water heater parameters calculation example:
Air Speed. Starting from 3500 m3/h on the air flow scale draw a vertical line 1 till the air speed axis which makes 4.65 m/s..

  • Supply air temperature. Prolong the line 1 of air flow up to the point where it crosses the outside air temperature (-10°C); then draw a horizontal line 2  from this point to the left till crossing water in/out temperature curve (90/70). From this point draw a vertical line 3 to the supply air temperature axis on top of the graphic (+22.5 °C).
  • Heating capacity. Prolong the line 1 up to the point where it crosses the outside air temperature (red line, -10°C) and draw a horizontal line  4 from this point to the right until it crosses water in/out temperature curve (90/70), from here draw a vertical line 5 up to the scale representing the heating coil capacity (42.0 kW).
  • Water flow. Prolong the line down to water flow axis at the bottom of the graphic 6 (0.5 l/s).
  • Water pressure drop. Draw the line 7 from the point where line 6 crosses the black curve to the pressure drop axis. (6.5 kPa).
