1. Summary

Introducing state-of-the-art comprehensive air conditioning that provides precise control for individual rooms.

RDH3 series : Lossnay Ventilation and efficient humiditying. RD3 series : Lossnay Ventilation and the Air conditioner.

(1)When the load is light. → Main Air conditioner. (2)When the load is heavy. → Supplemental Air conditioner.

Introducing the latest advancement for total air conditioning comfort – the Outdoor Air processing unit (hereafter OA processing unit). It uses the latest technology to provide comprehensive air conditioning control including ventilation, heat recovery, humidifying, heat processing and dust removal*. Control can be performed for each room, giving the flexibility to create the best comfort for each type of living space.

Note: (Dust removal) ......This function is enabled by using the optional high-efficiency filter.

The supply fan

Maintenance cover

EA (Exhaust air)

The heat of room air is recovered (sensible and latent heat) by Lossnay Core, and exhausted to the outside of the room by the exhaust fan.

OA (Outdoor air)

Fresh outdoor air in a quantity corresponding to the required ventilation rare is taken in by the supply fan.

Lossnay Core

Temperature and humidity are recovered between supply air and exhaust air.

Air filter

Prevents clogs in the Lossnay Core.

Direct Expansion coil

The outdoor air taken in is cooled or heated by Direct Expansion coil.

Permeable-film humidifier

Outdoor air taken in is humidified by the permeable film humidifier as required for more comfortable air conditioning. Not available on GUF-50/100RD3.

SA (Supply air)

The fresh outdoor air processed is supplied to the inside of rooms.

RA (Return air)

Contaminated room air is sucked by the exhaust fan.

CHAPTER 1 ● Product Section

2. Main Functions of OA Processing Unit

2.1 Common Functions of Humidifying/Non-Humidifying Type (GUF-RDH3/RD3)

●

Ventilation

Ensures proper ventilation by simultaneous forced air induction and exhaust.

Dual intake fans are used to simultaneously force both supply air diffuser and exhaust. This means that even sealed buildings will be ensured of proper ventilation.

●

Heat recovery

Heat recovery system that provides energy-saving operation.

The unit has a built-in static type total heat recovery unit Lossnay Core. There is no mixing of the intake and exhaust air as they pass through the Lossnay Core. Recover of both temperature (sensible heat) and humidity (latent heat) – in other words total heat recovery – is performed with minimal loss to the heating or cooling effect, ensuring energy-saving operation.

●

Dust removal*

High-efficiency filter provides 65% filtration using colorimetric method (Optional parts)

The high-efficiency filter provides up to 3,000 hours of maintenance free operation and is capable of 65% filtration (colorimetric method). It can be installed inside of the OA processing unit itself, so no additional installation space is required. In addition, the high-efficiency filter can be installed after the OA processing unit has been installed. Note: This function is enabled by using the optional high-efficiency filter.

●

Free Cooling

When the air conditioning system is operating in its cooling mode and the temperature of the air outdoors drops below the temperature indoors (e.g.a summer night), the OA processing unit detects this and automatically switches to a mode of operation which bypasses the heat-exchange element. Bringing in cool air from outside serves to help reduce the air conditioner’s cooling load.

2.2 Functions of Humidifying Type (GUF-RDH3)

●

Humidifier

Total introduction of permeable-film humidifier that functions using natural evaporation.

The humidifier installed in the OA processing unit was designed exclusively by Mitsubishi Electric. It is the permeable-film humidifier that functions using natural evaporation. This design total eliminates the spreading of impurities such as breaching powder and silicon dioxide. This means that this system can provide a clean supply air diffuser free of white exhaust.

●

Heat processing

Efficient heat processing and compact design allows for design freedom.

By including the direct expansion coil, approximately 25% of the air conditioning load can be heat processed by the OA processing unit. This means that the air conditioning unit itself can be more compact. And since it totally processes the outdoor air loads, it is possible to separate outdoor air loads and indoor air loads, allowing the freedom for easier installation designs. In addition, air passes through the permeable film humidifier that increases its heat and ensures proper humidity content.

2.3 Functions of Non-Humidifying Type (GUF-RD3)

●

Air conditioning

The high-performance direct-expansion coil and the air conditioning and Lossnay Core allow a single OA processing unit to provide low-energy heating and cooling ventilation.

9. Construction and Principle of Heat Recovery Unit (Lossnay Core)

●

Simple construction

The Lossnay Core is a cross-flow total heat recovery unit constructed of plates and fins made of treated paper. The fresh air and exhaust air passages are completely separated allowing the fresh air to be introduced without mixing with the exhaust air.

●

Principle

The Lossnay Core uses the heat transfer properties and moisture permeability of the treated paper. Total heat (sensible heat plus latent heat) is transferred from the stale exhaust air to the fresh air being introduced into the system when they pass through the Lossnay Core. Try this simple experiment. Roll a piece of paper into a tube and blow through it. Your hand holding the paper will immediately feel warm. If cold air is blown through the tube, your hand will immediately feel cool. This means heat is transferred through paper. Lossnay Core is a total heat recovery unit that utilizes these special properties of paper.

●

Treated paper

The paper partition plates are specially treated so that the Lossnay Core is an appropriate heat recovery unit for the ventilator. This paper differs from ordinary paper, and has the following unique properties.

(1) The paper is incombustible and is strong.

(2) The paper has selective hydroscopicity and moisture permeability that permits the passage of water vapor

only (including some water-soluble gases).

(3) The paper has gas barrier properties that does not pass gases such as CO

A comparison of the ordinary paper and the Lossnay Core plates is as shown in the table.

Ordinary paper

Water vapor is transferred, but gas elements that are easily dissolved in water such as CO2, NO2 are also transferred.

The contaminated air passes through the plates during ventilation and returns to the room.

Total heat recovery mechanism

Sensible heat and latent heat

The heat that enters and leaves in accordance with changing temperature (rise or drop) is called sensible heat. The heat that enters and leaves due to the changes in the physical properties of the matter (evaporation, condensation) is called latent heat.

(1) Heat (sensible heat) exchange

1) Heat conduction and heat passage is performed through a partition plate from the high temperature to low temperature side.

2) As shown on the right, the heat exchange efficiency is affected by the resistance of the boundary layer, and for the Lossnay Core there is little difference when compared to materials such as copper or aluminium which also have high thermal conductivity.

11. Principle and Features of Permeable Film Humidifier

11.1 Principles and Construction of Permeable Film Humidifier

Basic

A permeable film type humidifier uses the basic characteristics of natural evaporation. In this model, those characteristics have been dramatically improved. The main points of the improvement are that the water is wrapped in an ultra-water-repellant porous film (the permeable film) that forms a surface for releasing the water vapor and that the surface are of this evaporating surface has been dramatically increased.

Principle

As shown in Fig. 1, there are tubes filled with water. Space is provided between these tubes for air to pass through, forming a “layered strip” design that ensures rectangular- shaped flow passages. Since the permeable film of the tube (ultra-water repellant porous film) allows water moisture to pass through in an evaporated state, the water in the tube is released from the surface of the tube in an evaporated state and is included with the passing air as shown in Fig. 1 (b). As can be seen by looking Fig. 2, spacers have been placed between the tubes of permeable film to form layered openings for air to pass through. This provides an extremely large humidifying surface area – 8.5 times larger than natural evaporation type humidifiers of the same size and offering an increase of humidifying performance that is 6 times greater.

CHAPTER 1 ● Product Section

Construction

1) The water supply unit is comprised of strainer, pressure reduction solenoid valve and supply pipe. This design ensures stable water pressure and water volume are supplied to the humidifier unit.

The strainer removes foreign material as water passes through the water supply piping. The solenoid valve opens to allow the water to be supplied while the pressure reduction valve ensures that water pressure is maintained at 7 kPa or less as water is supplied to the humidifier unit. (If the water pressure exceeds 7 kPa, the safety valve opens and the water is discharged to a drain.)

2) As explained in the operating principles for the humidifying unit, the tube-shaped permeable film is arranged in a layered construction and spacers have been provided to create opening for the air to pass through. Water is supplied to these tubes and then evaporates from their surfaces into the air.

Note that any impurities in the water settle to the bottom of the tube and, due to the extremely large surface area of the permeable film, have almost no affect on the creation of humidity.

11.2 Features of Permeable Film Humidifier

Design of the new type permeable film type humidifier

The previous type of permeable film had a selective-type permeable layer that only allowed water vapor to pass through surfaces in contact with water and base cloth with a layer of porous PTFE with extremely fine pores with 1/20,000 water droplets and 1,000 times water vapor (0.1 to 1 µm) that allowed evaporation without air or water passing through. The new type permeable film does not have the base cloth used in the previous permeable membrane. Instead, it has an ultra water-resistant porous permeable film that reduces the resistance to permeation by 1/2 when compared with the previous type and a 3-dimensional fabric that ensures water passages inside the permeable film tube, dramatically improving the ability for water vapor only to permeate.

●

New type permeable film type

●

New unit

●

3-dimensional fabric

The 3-dimensional fabric inside the new type of permeable film tube is comprised of spiral-like threads that are attached upright in the tube. These act as a type of reinforcing material for ensuring the passage of water inside the permeable film tubes. This 3-dimensional fabric used in the new type permeable film type humidifier keep the permeable film tubes from collapsing and ensure that the water supplied at a constant pressure from the water supply port at the base of the humidifier seeps to the ends of the humidifying surface.
