Solar Enhanced Ventilation Installations

The patented Solar Enhanced ventilation System (SEV) provides solar assisted ventilation, and solar hot water to a home. It is programmed via the Intelligent Renewable Energy System (Ires) controller.

Solar hot water panels installed on the roof of the home. A solar hot water storage tank is installed. There will be more solar panels installed on the roof than a normal solar hot water heating system. So the amount of free solar energy available to use increases. It is this solar energy that will be used for the solar hot water heating, and solar assisted ventilation.

Solar Hot Water: Solar energy from the solar panels is sent to the sev. It is then sent to a coil at the bottom of the solar hot water tank. This heats the water in the tank. This provides the hot water for the house.

Solar Assisted Ventilation. The home is supplied with fresh air. When required this air can be warmed via solar energy. The system has two methods for heating the air.

(1) During daylight solar energy from the solar panels is sent to a water to air heat exchanger. The exchanger uses this energy to warm the fresh air entering the house. The house is supplied with warm fresh air.

(2) Throughout the day the solar hot water tank can act as a heat store for the solar energy collected. At night no solar energy is available.  The ires controller sends this energy to the ventilation system . This uses the energy to warm the air in the house.

Positive Input Ventilation. The SEV works like a Positive Input Ventilation (PIV) system. The Ires controller monitors the conditions in the house. It then adjusts the fans in the ventilation unit. This ensures comfort levels and freshness in the house. PIV systems pressurise a house. This is important as it helps to reduce air leakage, i.e warm hot air escaping.

All three elements of the SEV will help to reduce the energy required for home heating.

The SEV is unique due to its capture of the low levels of solar radiation. In Ireland during winter, the solar energy collected is not strong enough to heat water in a solar tank. So the solar energy would not be collected in a normal solar hot water heating system. During winter months the Intelligent Renewable Energy System (Ires) uses this low grade solar energy (around 30C). It sends the solar energy to the ventilation unit, providing warmed air at 28C to the house. This increases the amount of “free solar energy”. This reduces the amount of energy required from the boiler. Helping to reduce home heating bills.
