Heat Recovery Ventilation How It Works







Copyright (c) 2015 Matt Reardon

In the market today, there are several partial solutions to the problem of your indoor air-quality. For instance, when you install an electrostatic filter in a forced-air heating system, it will cut down your airborne contaminants, except that it won't aid you with eradicating gaseous pollutants, moisture and the stale air in your home.

Local exhaust fans may assist in removing excess moisture from your bath, kitchen and laundry area, but it will generate negative pressure within house. As the exhaust fans pump air out, the vacuum that is created will slowly draw in air into your house through structure gaps and vents, bringing along dust, contaminants and bad odors. In locations where radon is an issue, the generated negative pressure could increase the levels of radon in your house.

A better solution is creating a balanced heat recovery ventilation system for your entire home. With this system, one fan will be blowing out the polluted stale air from your house whilst another is replacing it with a fresh supply.

Holding the Heat

Similar to a balanced home ventilation system, a heat-recovery ventilator (HRV) warms up the incoming fresh air using the heat contained in your outgoing stale air. A classic unit has two fans--one taking out used household air while the other brings in fresh air to replace the outgoing bad air.

Heat-Exchange Core

This is the aspect which makes your HRV unique. The heat exchange core is responsible for transferring heat from your outgoing air stream to your incoming air stream similar to the manner in which a car radiator will transfer heat from the coolant of the engine's to the external air.

It's made up of a series of alternating narrow passages via which outgoing and incoming airstreams run. As the two streams are moving through, heat is transferred from the warmer air side of each passage onto the colder, whilst the two air airstreams will never mix.

Energy Efficient Consumption

Depending on your model, heat recovery ventilators could recover close to 85% of the heat contained in the outgoing stream, making them a lot more comfortable for your energy budget. Your HRV has filters which keep particulates like dust and pollen from getting into your house. You could however, discover that your energy bill has slightly gone up for replacing some of the heat which isn't recovered.

Energy and Buildings Journal Vo. 43 Issue 7, July 2011 published a study which concluded that though, VHR systems could give you considerable energy cost reduction, the benefit will strongly depend on the kind of heat supply system you got, plus on the quantity of electricity utilized for VHR and on your home's air tightness. The same study showed the implication of considering the linkages between VHR systems and your heat supply systems to decrease primary energy usage in homes and buildings.

Another study on the REHVA European HVAC Journal indicated that in passive and low energy homes, at least 50 per cent of the thermal heat is generated through ventilation. Therefore, requirements for thermal heat could only be notably reduced by utilizing heat recovery in your ventilation systems. The REHVA Journal is a practical and technical journal primarily for the professionals in the HVAC industry.

Types Of Whole House Ventilation
Copyright (c) 2015 Matt Reardon Ventilation in any home is a very important process (which has an impact on health and comfort), which involves letting in fresh air and getting rid of stale air. Air is exchanged between the indoors and outdoors, and the one inside is circulated constantly. In addition to reducing moisture levels in the air ventilation also manages to get rid of odors. There are different systems that are used in whole house ventilation: 1. Heat Recovery Ventilation Systems...

How Heat Recovery Ventilation HRV Works And Its Benefits
How Heat Recovery Ventilation (HRV) Works And Its Benefits Copyright (c) 2015 Matt Reardon Excessive condensation in your home could pose a health risk to all those residing there. In a scientific study titled Home Mechanical Ventilation In Australia and New and published in the European Respiratory Journal, there was found to be a direct positive correlation between spreading of respiratory disease and the usage or non-usage of home mechanical ventilation. The buildup of extreme...

Available Home Ventilation Options for Your Home
Copyright (c) 2015 Matt Reardon There are a number of reasons why ventilation is much more important today, than it was a couple of centuries ago. Most significantly, a hundred years ago houses were, if truth be told, extremely leaky. Typically they lacked insulation in their walls, such that fresh air could easily penetrate via all the numerous cracks, holes and gaps in the building structure. However, today, according to the Australian Bureau of Statistics (ABS) 2012 Australian...

Heat Recovery Ventilation Options for Your Home
Copyright (c) 2015 Matt Reardon Study results published in the International Journal of Ventilation, Volume 2 No. 3 of Dec 2003, have indicated that in climates that are colder, energy efficiency could be improved considerably by employing a heat recovery ventilation system. Results have indicated that a conventional exhaust system may use up to 67 per cent more energy compared to heat recovery ventilation (HRV) system. How does HRV Work? Even though an HRV could be quite effective during...

The Heat Recovery System in Whole House Ventilation
Copyright (c) 2015 Matt Reardon Heat Recovery ventilation is an energy-efficient method of ventilating a home. It is an example of an energy recovery system. The point of whole house ventilation is to keep the air in the house circulating, let in air from the outside environment and get rid of any smells. In addition, it dehumidifies the air. How it works It has inbuilt fans that propel air and a heat transfer system that exchanges air between the indoor and outdoor. Filtered incoming...

Why You Need A Heat Recovery Ventilation System
Copyright (c) 2015 Matt Reardon Our daily activities within our homes are generating both pollutants and moisture in vast quantities. The increasing levels of moisture are coming from our washing, cooking, bathing and breathing. When it reaches excessive levels, the moisture will condense on your windows and may lead to structural deterioration of your house, not to mention the health implications for you. Areas that are prone to excessive moisture also become rich breeding grounds for...

Why You Need Sub Floor Ventilation
Copyright (c) 2015 Matt Reardon Having ventilation systems installed beneath your floors has many benefits. Here are five of them. 1. Healthier individuals Damp air is known to cause respiratory diseases and trigger allergic reactions. The chain runs like this: Damp air encourages mold to grow and multiply. Condensation occurs and the liquid formed provides an excellent environment for fungi to grow. Mold produces substances that when inhaled by asthmatic individuals, induce attacks. Mold...

How Sub Floor Ventilation Works
Copyright (c) 2015 Matt Reardon Ventilation of the home through the floor is done by having vents and grilles so fresh air can be let in and out through the ground. Sometimes though, this is not adequate. Sub floor ventilation is a system of pumps, vents and fans that draw in air from the outside, eliminate the stale and circulate the one beneath. The system also draws out excessive moisture from the air. This part of the house is particularly susceptible to high humidity because of...

The Benefits Of Having A Good Home Ventilation System
Copyright (c) 2015 Matt Reardon Condensation, mildew and mould thrive in many poorly ventilated homes, leading to incidences of asthma and several other respiratory illnesses. When you have a cold and damp house, you and your loved ones are prone to ill health and hence the need to have a good ventilation system for your home. In Australia, when planning for a ventilation system for the house, there are several building code requirements which you should be aware of. For example, the...

Wet Area Ventilation Options
Copyright (c) 2015 Matt Reardon Condensation in your home can damage materials and surfaces. When left unchecked for long periods, it will lead to fungal growth. Some parts of your home generally experience excessive wetness due to the nature of activities being carried out there. In particular, bathing, showering, drying clothes and cooking generate excessive levels of moisture. When not checked or removed, the moisture in the air will tend to condense as water whenever it comes into...
