|HEAT RECOVERY VENTILATION IN THE CLASSROOM|
Bad air quality
Insufficient ventilation in school classes, offices and conference halls results in bad air quality, i.e. high humidity level and CO2 concentration, low oxygen level. That provokes well known symptoms like dryness and irritation of ocular mucosa, lack of concentration, fatigue.
Bad air quality was proved to be the reason of work capacity reduction by 5-10% for adults. Children are affected even more. Thus bad air quality is one of the factors that impair success level of children at schools.
High humidity may lead to growth of mold and germs in a building, which means a risk of asthma and allergy attacks. Quality ventilation is one of the key factors to prevent such diseases. Window ventilation is a standard ventilation solution, but this method has a short effect and it also leads to heat losses.
Window ventilation is not able to solve a problem of high CO2 concentration, which several times exceeds a permissible level. Single-room ventilation, as opposed to window ventilation, provides a stable good air quality and saves heat energy.
Problem with heat losses
Reduction of heating costs is one of the main targets to be solved by reconstruction of schools and other public premises. Modern windows and doors are a part of this energy saving strategy due to their high density. At the same time airtight premises require efficient ventilation with heat recovery to maintain high air quality with low energy demand.
Limited mounting space for ventilation in reconstructed premises
Reconstruction of old buildings poses many engineering challenges requiring non-standard solutions. Arrangement of efficient ventilation system is one of such targets. However very often there is not enough space for mounting of air ducts and ventilation in renovated premise. In this case central ventilation is infeasible. Engineers select the single-room ventilation as it offers required ventilation solutions without the need to mount air ducts. It can be installed directly in the room to be ventilated.
The CIVIC EC LB units are designed for single-room ventilation of schools, offices and other public and commercial premises.Offer the ideal simple and efficient ventilation solutions for existing and renovated buildings and require no layout of air ducts.
Efficient supply and extract ventilation for separate premises.EC motors with low energy consumption.Low-noise operation.
Made of high-quality polymer coated steel, internally lined with heat- and sound insulation of mineral wool or other materials.Built-in preheater and reheater modifications available for cold climate conditions.
High efficient electronically commutated motors with external motor and impeller with forward 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 electronically commutated motors.
Supply and extract air is purified by a set of panel filters. Filtering class depends on the unit model.Panel G4 filter is used for extract air filtration.
|BYPASS||CONTROL AND AUTOMATION|
The units are equipped with a bypass. The bypass damper opens for free cooling ventilation mode in summer.
The CIVIC EC LB 300 S25 units are equipped with an integrated automation system.
The CIVIC EC LB 300 S25 units are equipped with an integrated automation system and the S25 wall mounted sensor control panel with LED-indication.
The automatic supply and extract air dampers are used to prevent uncontrollable air draughts during the unit standstill.
CIVIC EC LBE and CIVIC EC LBE2 units are equipped with an electric preheater which protects the heat exchanger from freezing.
CIVIC EC LBE2 units feature an electric reheater to raise the supply air temperature.
|HEAT EXCHANGER||AUTOMATION FUNCTIONS|
The CIVIC EC LB unit has a counter-flow heat exchanger made of polystyrene.
• In cold season the heat energy of the extract air flow is absorbed by intake air flow, thus decreasing the heat losses caused by ventilation. Condensate generated during heat recovery is collected in a drain pan and removed to the sewage system.
• In warm season the heat of the outdoor air is absorbed by extract air flow. This way the supply air temperature decreases and heat recovery reduces operation loads for the air conditioner.
The CIVIC EC LB... -E unit is equipped with a counter-flow heat exchanger made of enthalpy membrane.
• In cold season the heat and moisture of the extract air are absorbed by supply air through the enthalpy membrane. thus decreasing the heat losses caused by ventilation.
• In warm season the heat and humidity of the outdoor air is absorbed by extract air flow through the enthalpy membrane. This way the supply air temperature and humidity decreases and heat recovery reduces operation loads for the air conditioner.
Cold outside air flows through the filters and heat exchanger and is moved to the room with a supply centrifugal fan.
Warm polluted air from the premise flows through the filter and the heat exchanger and is exhausted outside with an extract centrifugal fan.
