Mitsubishi Electric US Cooling & Heating Division's (Mitsubishi Electric) advanced line of Energy Recovery Ventilators (ERVs) meet the growing demand for improved indoor environmental quality (IEQ) in buildings while also helping to satisfy requirements of ASHRAE standards 62 and 90.1. The Lossnay® ERV recaptures cooling and heating energy and helps to equalize humdity levels and remove harmful indoor pollutants.

"The Lossnay system's compatability with CITY MULTI and Mr. Slim technology allows for easy maintenance and troubleshooting," says Mike Smith, senior product marketing manager, Mitsubishi Electric US Cooling & Heating Division. "Lossnay enables users to target different zones with varying heating and cooling needs on a case- by-case basis."

According to Miskewicz, the Lossnay cross-flow is key to the system's ability to improve IEQ. A low-maintenance energy exchange core constructed of a specially treated cellulose fiber membrane prevents the inbound air and exhaust air from mixing while exchanging energy to precondition the air. At the same time, Lossnay ERVs (pictured left) exhaust irritating indoor pollutants such as formaldehyde, pollen, cigarette smoke, dust, and carbon dioxide.

The Lossnay models transfer and exhaust airstreams through adjacent passages in the Lossnay core with minimal cross contamination. In cold months with low humidity, inbound air is warmed and humidified with the warmer indoor air; in warm months, air is cooled and dehumidified with the cooler exhausted air. This minimizes the load on the cooling and heating system. Humidity control is enhanced because the ERV's core incorporates heat transmission plates specially treated to allow water vapor molecules to pass through and to help equalize the indoor humidity levels.

"In a nutshell, Lossnay ERVs help improve the efficiency of HVAC systems by pre- cooling or pre-heating incoming outside air with the available energy in the stale exhaust air," says Smith. "The ERVs are cost-effective, energy-effective and provide a healthier living and working environment."

Within the LGH-F-RX3 series, there are four available ERV models offering CFM levels from 300 to 1,200 and two remote controllers – one for use with Mitsubishi Electric's M- NET controls network and one for independent control. Lossnay ERVs are compatible with TG-2000 software, LMAP LonWorks® device and BACnet, further increasing the scope of total system management. Additionally, each Lossnay ERV unit comes standard with the M-NET adapter, so networking systems connected with CITY MULTI VRFZ systems has never been easier.
