Ventilation

Ventilation Overview

A heat recovery ventilation unit provides a clean, fresh environment into your building. It delivers fresh filtered air from outside the building to your working environment and extracts stale air from high moisture areas.

At the same time it recovers up to 95% of the heat from the exhaust air and transfers it to the incoming air. With a heat recovery ventilation unit you can maintain a high air quality without excessive additional energy costs.

How the Lossnay RVX Systems work

The technology behind the energy efficiency of the Lossnay sysetm lies in the construction of the core which enbles exchange of both latent heat (humidty/moisture) and sensible heat (temperature) to maintain a comfortable internal environment for minimal energy consumption.

The Lossnay core is essentially a diaphragm made of specially processed paper which fully separates the inlet and exhaust air supplies ensuring that only fresh air is introduced to the indoor environment.

Why Lossnay uses a total Heat Exchanger

Traditional forms of MVHR use plastic or metal cores only allowing sensible heat recovery, Lossnay’s paper core allows total heat recovery including both sensible and latent heat.

Lossnay’s simultaneous air exhaust and supply provides balanced and effective ventilation allowing for a clean, fresh internal environment to be maintained in an energy efficient and cost effective manner.

The benefits of a total heat exchanger include:

• Controlled humidity levels
• Dry eye and dry throat prevention
• Static reduction
• Higher heat transfer efficiency

Example

One LGH-25RX5 serving one PLA-RP71BA. Room size 7m x 7m, 140w/m2 heat load. 7 people per room, 10l/s/person of fresh air to meet Part F requirements. Maximum amount of fresh air to be introduced is 30% of the fan coil volume. Ceiling cassettes may require fresh air casements. Free cooling is not available below 8ºC when interlocked with Mr Slim or City Multi units.
