Energy Recovery Ventilators▶▶ Maintain an adequate supply of ventilation air while reducing energy costs.▶▶ Recover up to 80 percent of sensible and latent energy from the conditioned air as it is exhausted.▶▶ Reduce extremes in humidity that can encourage mold growth.▶▶ Remove dangerous gases, bacteria, and other airborne impurities from conditioned air.

Mitsubishi Electric’s Lossnay energyrecovery ventilators offer:

▶▶ Unprecedented energy transfer in a fixed-plate component with no moving parts.▶▶ Reasonable paybacks and reduced peak demand.▶▶ Superior part-load per performance, reducing latent load even at mild outdoor temperatures.▶▶ No wheels to stop turning so outside air is always preconditioned and available.

How does the Lossnay®

core work?

Outside Air Makes the Difference!People need outside air for their health and comfort. Unconditioned outdoor air rarely

meets their needs: it’s usually too hot and humid in the summer and too cold and dry

in the winter. To provide the benefit of ventilation, the air must be preconditioned

before being introduced into the occupied space.

Cooled or heated indoor air soon grows stale and must be exhausted to rid the

building of toxins, odors, viruses, bacteria, and other potentially harmful contaminants.

Exhausting that air and replacing it with outside air, which must be conditioned, is

critical to a healthy and productive environment, but it is a process that can be both

costly and inefficient.

If your air-conditioning system utilizes an energy recovery ventilator (ERV), these costs

are greatly minimized. An ERV helps improve the efficiency of air-conditioning systems

by preheating or precooling incoming outside air with the available energy in the stale

exhaust air.

ERVs save money by decreasing the load on your air-conditioning units;

helping remove noxious indoor pollutants, such as formaldehyde, pollen, cigarette

smoke, dust, and carbon dioxide; and helping equalize humidity levels. An ERV is an

efficient and effective step toward improving overall indoor environmental quality.

At the heart of each Mitsubishi Electric Lossnay energy recovery ventilator is a low-maintenance cross-flow energy exchange core constructed of a specially treated cellulose fiber membrane.

The low-maintenance ERV core prevents the inbound air and exhaust air from intermingling while crossing the airflows, thus preconditioning the air by warming it in the wintertime with the warm exhausted air, or by cooling it in the summertime with the cooler exhaust air.

While the airflows are exchanging heat energy by conduction in the ERV core, the humidity in the airstreams seeks to equalize. In the winter cool dry supply air from outside is partially humidified by the moist exhausted air, and the opposite occurs in the summertime. The special treatment and impregnation applied to the transmission plates allows water vapor molecules to pass through so the differing humidity levels move toward equilibrium in the Lossnay core. Larger molecules are unable to pass through the transmission plates, so the outside air is uncontaminated by stale exhausted air.

FeaturesMitsubishi Electric has responded to the growing need for total, integrated management of building HVAC and indoor air quality by making it easier to interlock and control Lossnay energy recovery ventilators with our air-conditioning systems.

Improved sound attenuation makes Lossnay units quiet enough for places where silence is a must, such as meeting rooms and libraries.

A free-cooling function is standard to help reduce costs and boost efficiency. The integrated bypass damper design makes installation and system integration quick and efficient.

System compatibility

Lossnay is fully compatible with our AE-200A, AE-50A and EW-50A Centralized Controllers and works with the TG-2000A software, LonWorks® interface, and BACnet® interface, further increasing the scope of total system management.

Multifunction LCD remote controlThe PZ-43SMF-E Remote Controller and the PZ-60DR-EM-NET Controller are compact and attractive. In addition to controls for ON/OFF and Ventilation Mode, the schedule for filter maintenance is also displayed. The liquid crystal display has been designed for easy visibility.

High-static pressure blades

By developing blower blades that are thinner, more widely spaced, and possessing a larger diameter of curvature, static pressure has been boosted and sound reduced while ensuring optimal airflow.Higher static pressure means that Lossnay canaccommodate the pressure loss required to meet the specifications of ductwork and terminal devices, increasing the flexibility of system installation.

Lossnay constructionLossnay ERVs are constructed so that the exhaust air passage from the indoor side to the outdoor side (RA EA) and the outside air passage from the outdoor side to the indoor side (OA SA) cross. The Lossnay energy recovery unit features the Lossnay Core, which is installed at this cross point and recovers the heat by conduction through the separating medium between the airflows. This enables the energy loss during exhaust to be greatly reduced.

VentilationWith conventional ERVs, bypass or auto ventilation was impossible without attaching an additional damper and adapter. With the LGH-F-RX5 series, however, these modes are available without using any other parts. Auto mode is the fixed setting when Lossnay is interlocked with air conditioners. When using Lossnay independently with the PZ-43SMF-E remote control (sold separately), Lossnay ventilation, bypass ventilation, or auto mode can be selected.

Reduce cooling load If the air outside is cooler than the air inside the building during the cooling season (such as early morning or at night), bypass ventilation will draw in the cooler outside air and reduce the cooling load on the system.

Cooling using outdoor air During cooler seasons (such as spring and fall), if the people in a room cause the temperature of the room to rise, bypass ventilation will draw in the cool outside air and use it as is to cool the room.

Night purge Bypass ventilation can be used to release hot air from inside the building that has accumulated during a hot summer day.

Office equipment room cooling During the cold season, outdoor air can be drawn in to cool rooms where the temperature has risen due to the use of office equipment. (only when interlocked with CITY MULTI®, M-Series, or P-Series indoor units)

Independent zoned ventilation methodThis is mainly used in small to medium-sized buildings, with areas being ventilated using outside air intakes from independent ventilation devices. The rate of use of this method has recently increased as zone conditioning and independent control is becoming more feasible.

Calculation of total heat recovery efficiencyThe Lossnay Core’s energy recovery efficiency can be considered using the following three transfer rates:1. Temperature (sensible heat) recovery efficiency2. Humidity (latent heat) recovery efficiency3. Enthalpy (total heat) recovery efficiency The heat recovery effect can be calculated if two of the above efficiencies are known. (The temperature and enthalpy efficiencies are indicated on pages 7–10.) Lossnay performance and cost analysis can also be determined using Mitsubishi Electric ERValue® software.• Each recovery efficiency can be calculated with the formulas

in the table below. • When the supply air volume and exhaust air volume are

equal, the heat recovery efficiencies on the supply and exhaust sides are the same.

• When the supply air volume and exhaust air volume are not equal, the total heat recovery efficiency is low if the exhaust volume is lower, and high if the exhaust volume is higher.

RACalculation of supply air condition leaving LossnayIf the Lossnay energy recovery efficiency and the conditions of the room and outdoor air are known, the conditions of the air entering the room and the air exhausted outdoors can be determined with the following formulas in the table below.

Supply side Exhaust sideTemperature tSA= tOA- (tOA- tRA) x t tEA= tRA + (tOA - tRA) x t

Enthalpy iSA = iOA- (iOA - iRA) x i iEA = iRA + (iOA - iRA) x i

Centralized ventilation methodThis is mainly used in large buildings, with the outside air intake being installed in one machine room. For this method, primary treatment of the outdoor air, such as heat recovery to the intake air and dust removal, is performed before distribution to the building duct system.

Interlock simply, effectively, and economicallyBecause the M-NET adapter is included as standard equipment on the LGH Series Lossnay Units, networking Lossnay Units with Mitsubishi Electric CITY MULTI has never been easier. Systems can be assembled simply and logically, reducing construction times and keeping costs low.

Fan speedSelect an appropriate Lossnay model according to the room size, air volume and sound levels. Each unit, (300, 470, 600 and 1,200 CFM), has an extra-high fan speed setting for use with a long duct or when a large air volume is required. Fan speed can also be adjusted for positive or negative zone pressurization.

Lossnay units have a low-sound design. However, for additional sound reduction, a silencer-type supply/return grill, a silencer box and a flexible silencer may be used.

Typical Installation

Duct can be installed in two different directions (OA, EA side)Ducts can be connected in two different directions to the outdoor vents thanks to collars and aperture plates that are interchangeable — either side or bottom locations. This flexibility allows for installations close to the surface of a wall and helps avoid cases where the stale exhaust air vent would be obstructed. This innovative feature simplifies both planning and installation.

Balanced Ventilation A ventilation strategy using both an exhaust air blower and a supply or make-up air blower providing the same airflow and pressure so as not to pressurize or depressurize a building.

CFMCubic Feet per Minute, a measure of air volume.

Delayed OperationThe On/Off operation of the Lossnay unit can be delayed for 30 minutes following the operation of the indoor unit. When using PZ-43SMF-E, the delay can be set for 0:30–24:00 hours.

ESPExternal Static Pressure, available motive force to propel air in a duct system from a blower or ventilator.

Enthalpy ExchangeThe exchange of both sensible and latent heat energy.

Exhaust Air (EA)Air expelled from indoor space.

External Control InputAn On/Off input signal for operating the Lossnay unit that can be sent from an external device. The signal may be a 12V–24V DC or an uncharged a-contact signal.

Interlocked LossnayLossnay unit linked to CITY MULTI, M-, S-, or P-Series Indoor units that receive signals and operates via the indoor unit’s remote controller.

Non-interlocked LossnayLossnay unit controlled independently of CITY MULTI, M-Series, or P-Series indoor units by the Lossnay remote controller and/or centralized controller.

Operation in Cold AreasWhen the outdoor air is less than 14°F, continuous operation of the fan for drawing in supply air is stopped, and intermittent operation is started.

Outdoor Air (OA)Air drawn from outdoors — ventilation air.

Pulse InputWhen the control signal from an external device outputs a pulse such as the one shown at right, the pulse input control is performed by the Lossnay unit. (Optional DIP switch 2-2 ON) 200 ms or more.

Remote OperationThis is used for enabling/disabling the On/Off control signal from an external device and for setting interlocked operation of the external device and the Lossnay unit. ON/OFF interlock: Enables both ON OFF and

OFF ON external signals. ON interlock: Enables OFF ON external signal.

Disables ON OFF external signal. OFF interlock: Enables ON OFF external signal.

Disables OFF ON external signal. External priority: Same as on/off interlock but the

OFF signal from the remote controller is ignored when the external control signal is on.

Return Air (RA)Air drawn from indoor space.

Supply Air (SA)Air supplied to indoor space.

Ventilation Modes Energy Recovery — energy exchange through

Lossnay core at all times. Bypass — no exchange—bypass damper open Automatic — energy exchange or bypass as

determined by present temperature sensor in inlet and discharge airstreams.
