RF system

VRF stands for Variable Refrigerant Flow.

A VRF air conditioning system modulates the

flow of refrigerant depending upon the capacity

requirements of the building. In its simplest

form, a VRF system comprises an air-cooled

outdoor unit and a series of indoor units that

regulate the air temperature inside an internal

space.

nverter driven technology

At Mitsubishi Electric we strive to continually

meet the increasing demands of our customers,

being the first in the industry to offer highly

advanced ‘inverter driven’ systems. Using

inverter technology our systems produce just

the right amount of output to match the exact

requirement of any building. These systems

work so efficiently that they don’t waste

valuable energy by over-heating or

over-cooling, resulting in greatly reduced

running costs. Alternative systems that may

appear cheaper, can often cost substantially

more to run, making us the most cost effective

choice all round.

ntelligent Power Module (IPM)

technology

The CITY MULTI range from Mitsubishi Electric

provides precise control of energy input,

through utilization of its Intelligent Power

Module (IPM) technology. By employing this

technology, highly efficient operation is possible

with compact units closely matching building

requirements.

R

410A refrigerant

As scientific evidence points to man-made

chemicals for the damage caused to the ozone

layer, we only use chlorine-free refrigerants

that are safe with zero ODP (Ozone Depletion

Potential). Accordingly, our systems require

less energy to run, and have a significantly

lower indirect global warming potential. In

short, we produce the most efficient equipment

possible, while helping to protect the environ-

ment.

nverter Driven Compressor

Technology - now up to 50HP

Using inverter driven technology
saves energy for several reasons:

The unique Heat Interchange Circuit (HIC) enhances efficiency by providing additional sub-cooling and allows the

expansion device to effectively control the refrigerant distribution, thereby increasing the operating efficiency and

reducing the volume of refrigerant in each system.

Heat Interchange Circuit

The compressor varies its speed to match the indoor cooling or heating demand and therefore only consumes the

energy that is required.

When an inverter driven system is operating at partial load, the energy

efficiency of the system is significantly higher than that of a standard fixed

speed, non inverter system.

The fixed speed system can only operate at 100%, however, partial load

conditions prevail for the majority of the time. Therefore fixed speed

systems cannot match the annual efficiencies of inverter driven systems.

Using proven single inverter driven compressor technology, the CITY

MULTI range is favored by the industry for low starting currents (only 8 amps

for a 16HP YJM-A outdoor unit), and smooth transition across the range of

compressor frequencies.

Comparison of COP (energy efficiency) – 8HP system

The difference between YJM-A and previous
Mitsubishi Electric models

Technology is key when increased efficiency is demanded.
The CITY MULTI YJM-A range is able to deliver this in simple ways.

The importance of COP

The YHM-A range from Mitsubishi Electric provides precise control of energy input, through utilization of its

Intelligent Power Module (IPM) technology. By employing this technology it is possible to closely match the

building requirements, achieving more accurate control of the occupied space. By using incremental 1Hz steps of

capacity control, the amount of power input required is significantly reduced, resulting in greatly improved COP’s.

In addition, IPM technology ensures effective performance under partial load conditions, a condition that most

systems will be in for the majority of the normal working life cycle. By taking account the efficiency at both part

load, and peak load conditions, R410A CITY MULTI is designed to provide unbeatable year round/seasonal

efficiency.

A highly efficient R410A scroll compressor design results in less friction losses at the motor. A simplified refrigerant

circuit (low pressure loss) including a new accumulator design also adds a few more points to the efficiency scale.

Enhancements to the heat interchange circuit, an inverter driven fan motor and a heat exchanger design again add

vital increases to overall system efficiencies and COPs.

COP stands for “Coefficient of Performance”. It is a measure of the useful energy a system can deliver compared

to the energy it consumes. It is calculated by dividing the energy output by the energy input of a system. The

higher the figure then the more efficient the system is deemed to be. Mitsubishi Electric VRF models, the world's

highest energy-efficient air-conditioners, will undoubtedly reduce millions of tons of CO2 emissions.

For the Environment

History of refrigerant

R22, an HCFC-based refrigerant, has been a popular choice for most chillers. R22 has been targeted by the

Montreal Protocol to be phased out in new equipment. Additionally, governments in many countries are enforcing a

ban of HCFC-based refrigerants for new installations.

Because of these restrictions, R410A refrigerants are desirable. R410A is a blend of HFCs, which do not deplete

the ozone.

Technical aspects of refrigerant

New Design

R410A is a more efficient refrigerant as it has a higher specific heat capacity when compared to R407C or R22.

This higher energy carrying capacity allows for smaller pipe sizes, longer pipe runs and reduces the volume of

refrigerant within a system. This is a major factor when concerning safety and environmental requirements in the

design, manufacture, installation, operation, maintenance and disposal or refrigerating systems.

Enhancing environmental care (measures for the RoHS Directive and the refrigerant reduction)

Every unit is in compliance with the RoHS Directive,* which stands for the Restriction of Hazardous Substances:

Lead-free soldering is used to avoid Lead Groundwater Contamination on the print board. The amount of

refrigerant on the unit has also been reduced to enhance environmental care.

* RoHS Directive: the restriction of the use of certain hazardous substances in electrical and electronic equipment that has been sold in EU since July 2006

Why Heat Recovery?

Flexibility and efficiency are key factors when selecting a heat recovery system. For example, while a heat pump

system is adequate for a large open-plan office, an office that has a more partitioned structure will require the need

to simultaneously heat or cool different sections of the office according to each user's individual preferences. The

efficiency of this type of system comes from the ability to use the by-products of cooling and heating to transfer

energy where it is required, thus acting as a balanced heat exchanger achieving up to 20% cost savings over a

conventional heat pump system. The number of connection sites needed for a R2 / WR2 system are also signifi-

cantly lower than those needed for a three pipe version. This helps to reduce installation costs, further increasing

the savings associated with CITY MULTI.

U

nique technology

By the heat recovery system, the more frequently cooling and heating simultaneous
operation is carried out, the higher energy-saving effect becomes.

Unique to Mitsubishi Electric, our heat recovery technology uses just two pipes,

as opposed to the market conventional three. Designed for effective simultaneous
heating and cooling our R2 and WR2 systems offer substantial savings on
installation and annual running costs.

What is Water-Cooled?

It is possible now to combine the features of VRF with a water circuit using CITY

MULTI WR2/WY. In this case the heat is rejected to a water source rather than to

the outside air.

The advantages of water cooled systems are that the water can be delivered at

optimised temperatures and volumes, which allows even greater flexibility and

increased COP.

WR2(Heat recovery type)

>A unique offering from Mitsubishi Electric

Mitsubishi Electric now offers double heat recovery operation.

The first heat recovery is within the refrigerant system. Simultaneous cooling and heating operation is available

with heat recovery performed between indoor units.

The second heat recovery is within the water loop, where heat recovery is performed between the PQRY units.

This double heat recovery operation substantially improves energy efficiency and makes the system the ideal

solution to the requirements of modern office buldings, where some areas require cooling even in winter.

Water cooled systems can be used even in buildings
that are taller than 50m by running a main water pipe
through each floor.

Any heat source system that can supply heat source
water between 10°C~45°C can be used.

Simultaneous heating and cooling operation is available.
(WR2 series)

It is suggested that Water-Cooled systems are used in the
buildings in which there are heating and cooling needs as follows.

Buildings that require all year cooling

Example,
Tenant buildings in which kitchens and offices exist together
Buildings in which equipment rooms and offices exist together

Buildings in which there are large room temperature
differences between sunny and unsunny rooms
Hotels in which there are a lot of individual operation needs

Centralized Remote Controller

The need for control is paramount in order
to optimise the performance of any air
conditioning system and minimize its
running costs. Mitsubishi Electric offers a
wide range of control options designed to
meet such needs.

Operating an air conditioning system without

the right control can prove costly. It's therefore

important to ensure that every system is

correctly specified to the degree of control it

requires. Mitsubishi Electric have a wide range

of controls available 'off-the-shelf' and

individual control systems can be specifically

designed to match.

Good controls will benefit any application,

large or small. Air conditioning products need

to react to a variety of factors: different room

sizes, usage and staff levels; changes in the

climate; electronic equipment and lighting ...the

list goes on. So whatever the application,

optimum control of air conditioning systems is

essential and will result in a constant,

comfortable environment, which in turn is both

energy and cost efficient.

A degree of difference

When an air conditioning system is not

properly controlled, it will not run as efficiently

as it should. For every degree that the system

deviates from the required temperature,

energy costs can rise by up to 5%. Specify one

of the many control options from Mitsubishi

Electric to ensure air conditioning works as

intended, whilst giving the optimum amount of

control.

The simpler, the better

With the array of comprehensive control

systems available from Mitsubishi Electric, it

becomes simple to design and install air

conditioning systems. From a simple

hand-held controller to a AG-150A system -

you are in control.

Up to 150 units can be controlled by AG-150A.*

*Expansion controller is required.

Effective use of TG-2000A

Multiple air conditioning charges in multiple buildings can be calculated. The power apportionment percentage
data and apportioned power rate can be calculated for each unit, and can be output as a CSV file.

For example, installing TG-2000A to the system in the headquarters makes it possible to control AG-150A/GB-50ADA*
units that are used in branch offices.

*It is planned that GB-50ADA will be supported on TG-2000A Ver. 6.3* or later.

Auto-fan-speed mode enables speedy and

comfortable heating during heating startup.

The Auto-fan-speed mode is added to the
usual four steps “Low, Mid1, Mid2, High.”
The Auto-fan-speed mode enables speedy
and comfortable air conditioning because the
air flow speeds up when starting, and air flow
slows down when the air conditioning
becomes stable. (PLFY-P VBM-E ONLY)
