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 cool air is heated by warm outgoing air continuously. The two streams of air are kept separate and the heat transfer occurs through the conducting vents in the system. The two jets of air flow counter to each other, maximizing the time taken to heat the air that flows in.

The fans on the system can be turned up or down so that during the summer, cooler air is let in.

Installation

It can be installed on roofs or floors. The air that comes in is then distributed throughout the house. For small homes, a single unit will do, while in big homes, several units can be installed in different positions throughout the house. Alternatively, vents can be laid in strategic positions that connect to the central system.

Benefits

It reduces heating and cooling costs.

It warms or cools your home depending on the season.

It improves the quality of air in the home to match Standard 62. 1 (Ventilation for Acceptable Indoor Air Quality) of the American Society of Heating, Refrigerating and Air Conditioning Engineers. (ASHRAE).

It eliminates pollutants from the air which could damage the lungs or trigger allergic reactions.

Carbon dioxide levels, present in exhaled air, is reduced.

It balances the humidity, so it remains at a percentage of about forty five percent, in line with Occupational Health and Safety Australia, and the Australian Department of Health.

Many homes are increasingly becoming air tight to conserve energy in the form of heat and power. However, this may pose a problem. It therefore becomes necessary to have an energy and cost efficient ventilating system for comfort and for the sake of your health. Otherwise, you are at risk of suffering from problems like Sick building syndrome caused by inadequate fresh air intake, irritability and fatigue.

According to Mould Fact Sheet Australia developed by the Australian Department of Public Health, humid stagnant air encourages mold to grow. Condensation and the subsequent moisture is an excellent environment for these type of fungi. Mould causes sneezing fits in some people and they can release a bad odor.

Some mold produce toxic substances that can cause neurological problems and allergies. The symptoms shown by allergic people include persistent coughs, itchy eyes and rashes. Again, mold destroys walls and wooden structures. Heat strokes are another real threat when a home is overheated and has high humidity. Asthma attacks can also be triggered by hot or cold humid air.

Get your home assessed for structural damage, especially on roofs and pipes. The expert will go on to recommend the best heat recovery ventilation system for your home.
