Ventilation on our life
How much fresh is the air we breathe in?
In everyday life, we do not think a lot about how much time we spend in closed spaces — houses, offices, office buildings, hospitals, etc. All this time we share limited volume of air of doubtful purity and freshness with our people in the same rooms. Unwellness, weariness, headache and other unpleasant symptoms are the first indicators of negative impact of polluted stale air on human health. Still, we rarely associate these conditions with poor air quality.
For human organism, the surrounding air quality has vital importance because metabolism is possible only due to oxidation, i.e. connection of chemical substances with oxygen contained in blood. In case of no oxygen supply, the oxidation process interrupts, and the life of the organism stops. Therefore it is vital for us to take ongoing care of purity and freshness of the air we breathe.
The air that fills the apartment and rooms contains a large number of bacteria and dust particles, all kinds of vapours, gases and other municipal waste particles of big city and human organisms that results in high pollution concentration. No need to say, breathing such air in, we rather bring harm to our health than consume vitally important oxygen.
In captivity of our own houses ...
„Any residential premise is always filled with air containing micro particles and various polluting components thus creating a certain air pollution degree inside. Well arranged ventilation and permanent air exchange bring indoor concentration of harmful substances within permissible limits that is not dangerous for human health.
But the situation changes drastically when some inhabitants driven by their desire to insulate their houses as much as possible thoughtlessly isolate all possible sources of natural air exchange by glazing balconies, insulating facades, sealing the window frames, doorways, blocking all the cracks and ventilation ducts. As a result, the modern houses made of brick and concrete, equipped with double-glazed windows, metal doors, additional outer insulation, etc., are practically hermetic structures.“
Striving to minimize heat losses and energy costs has resulted in almost perfect insulation of buildings and blocked any possibility of natural air motion and air exchange. Under such circumstances, the natural ventilation does not provide sufficient air supply, consequently, a tightly closed house just „does not breathe“. The rooms or premises that are thermally well insulated and sealed in plastic windows cannot avoid excessive moisture which provokes formation of various bad smells, including foul smell, feeling of stale air, various pollutants, even mould. Microclimate in this house becomes harmful for its inhabitants and for the house structure, too.
The air in your house – a closer look under the microscope
There are at least two sources of air pollution in any building. The first one includes the construction materials used for the building construction which produce more than 50% of overall pollution. people and their life activity form the second source of pollution.
Various suspended solid particles and microorganisms which are brought into a house by people, animals or penetrate through improperly maintained vents and ducts are always found in indoor air. In poorly ventilated areas, these microorganisms can cause unpleasant smell, sense of discomfort, lung ailments displayed by sneezing attacks and even give rise to a variety of bacterial infections.
Emissions of various chemical substances used in cosmetics and detergents as well as dust, vapours, tobacco smoke, formaldehyde that is vapored into atmosphere from synthetic carpets, polyurethane foam insulation, finishing materials, furniture, harmful chemicals emitted from household electric devices, concentrated carbon dioxide and radon are only few pollutants.
As a result, we feel stuffy air in a house with closed windows, air becomes stale, temperature and humidity increase, and finally that causes genera feeling of weakness, weariness, poor sleep and other symptoms. Poor air quality is detrimental not only for the people in the house but for the house itself as condensate volume on the glass and mirrors increases, fungus and mould in the bathroom or kitchen appears, unpleasant smell of moisture persists.
The ventlight is not a good solution
Partially the polluted air problem can be solved be creating natural ventilation through window opening. But even that solution has some drawbacks. Ventilation through open windows brings to uncontrolled excessive air flow and creates unsafe draughts. By opening windows you fill the room not with clean air but with a mixture of pollens, poplar stuff, dust and exhaust fumes. Moreover, thermal losses rise together with high energy costs. Furthermore, noise level from outside may be a catastrophe. That refers in particular to inhabitants of the houses located near main city highways and entertainment places, intersection of basic routes and transfer transport points. Thus, we hardly make such ventilation useful but we let extra irritants and pollutants enter our rooms. Even worse, we do not solve the problem of polluted stale air removal.
THERE IS A SOLUTION!
In order to eliminate the problems associated with health risks, the wet, polluted air must be regularly removed outside and replaced with fresh air. Supply air must always penetrate into all rooms of the house or apartment to ensure full and effective ventilation. Therefore, arrangement of the effective forced supply and exhaust ventilation in the rooms or premises is the only correct and rational solution of this problem.
How can i install ventilation in the ready-built house?
TwinFresh – a comfortable climate in your home
Installation of TwinFresh single-room reversible ventilators with energy regeneration is the most state-of-the-art and practical way to arrange a comfortable microclimate and the required air exchange in refurbished premises, brand new recently inhabited houses or reconstructed apartments.
The TwinFresh single room ventilators are the ready ventilation units that provide supply of fresh air to the premise, its filtration and extract of polluted air outside. You do not need to purchase some extra ventilation equipment or its components to create efficient ventilation system. Installation of a pair of TwinFresh ventilators is an efficient full-fledged ventilation system of your premise!
The great advantage of the TwinFresh ventilators is their ability to regenerate heat and humidity balance in the premises due to use of a special ceramic thermal accumulator (energy regenerator). Energy regeneration is based on use of the heat and humidity of the removed polluted air from the premise for heating and moisturizing of intake fresh air from outside. In view of permanent heat losses in the room use of the heat utilization is the most useful technology for cost and energy saving.
The heat regeneration rate of the TwinFresh single room ventilators is very high and reaches 91%. Meanwhile one TwinFresh unit provides permanent balanced air exchange and air filtration required for ventilation of the area up to 50 m2. The best result is achieved by using the TwinFresh ventilators in the same room in pairs for creation of the most comfortable microclimate.
Basic heat losses in the house:
Basement - up to 15%
Outer walls - up to 15%
Windows, doors - up to 17%
Ventilation system - up to 50%
Roof - up to 10%
Supply of fresh heated air free combined with minimum noise and energy demand are three main advantages of the TwinFresh ventilators.
The TwinFresh single room ventilators are applicable at any project stage and suitable for any room, starting from design of the ventilation system during construction of a new object, including reconstruction of existing buildings and premises, ordinary scheduled repair and finishing with ready-made premises, where installation of centralized ventilation devices is unfeasible. The ventilators have user-friendly design depending on application area, e.g. the TwinFresh S model with a square telescopic duct is normally used for facilities under construction whereas the TwinFresh R modes with a round telescopic duct is used for ready-built or reconstructed buildings.
Simple and easy to use
The TwinFresh compact ventilators do not require any extra components or air ducts. They are ready for use. The ventilators are designed for through-the-wall installation to the outer wall of the buildings. The only thing you need is a through opening in the wall, which is closed with a decorative ventilation grille matching any interior design. The outer side is covered with an outer hood for prevention of direct penetration of water and foreign objects into the ventilator.
The efficient, reliable, energy-saving and cost-efficient TwinFresh ventilators work round the clock to:
- supply clean fresh air to the premises
- remove stale extract air from the premise
- clean the air from dust and insects
- prevent penetration of excessive humidity and appearance of mould
- protect against outdoor noise
- regenerate heat and provide humidity balance inside
- reduce the heating costs in winter and air conditioning costs in summer
- require low energy demand
