Mechanical ventilation heat recovery systems from Mitsubishi Electric

Mitsubishi Electric’s Lossnay RVX mechanical ventilation heat recovery (MVHR) series has been designed to provide ventilation whilst reducing carbon emissions

The new Lossnay RVX models use a DC fan motor which gives them lower specific fan powers (SFPs).

The series’ specific fan powers range from 0.30 W/(l/s) to a maximum of 1.61 W/(l/s). These lower SFPs help the units meet Building Regulations whilst simultaneously allowing for reduced carbon emissions.

The new units have a wider air volume range. Four fan speeds can be selected, with each one being 25%, 50%, 75% and 100% of the rated air volume of each unit.

A weekly timer function allows each fan speed to be individually chosen. With this feature, ventilation can be enhanced across individual days as well as on different days of the week.

With 0-10V DC signal, the fan speed can also be controlled externally with a third party CO2 sensor or a BEMS system.

Depending on the internal and outdoor conditions, the RVX unit automatically switches the Lossnay units between heat recovery mode and bypass mode.

A new PZ-61DR-E Lossnay controller unified with the PAR-31MAA air conditioning controller is also included within the range.

The Lossnay RVX units can be worked using Mitsubishi Electric centralised controllers, which makes them easy to use in commercial buildings.

The units are also able to interlock with Mitsubishi Electric Mr Slim and City Multi air conditioning systems.

Increased energy efficiency

The Lossnay system has been designed to prevent stale air from building up in insulated establishments. It has been developed by Mitsubishi Electric to ventilate buildings and rid them of excess humidity.

The system can recover up to 89% of the heat energy from outgoing air, which reduces the amount of energy needed to bring the incoming air up to room temperature. This benefits the environment.
