Comparison between VRV/VRF Suppliers @ UAE May-2016 up-date

ASHRAE defines the VRF as follows: "It is a multi-

split system direct expansion (DX) incorporating at

least one variable capacity compressor, which

distributes coolant through a network of pipes to

multiple indoor units of air conditioning, each of

which is capable of controlling the temperature of

separate zones through control devices integral

temperature zone and a common communications

network. The variable refrigerant flow uses three or

more steps in the shared control and

intercommunicating pipe ".

The AHRI defines VRF follows: "Multi-split system

VRF: A heat pump or multi-split air conditioning

incorporates a single refrigerant circuit, with one or

more outdoor units, at least one variable speed

compressor or a combination of reciprocating

compressors for varying the capacity of the system

in three or more steps, several inner air-

conditioning units (each of which is measured

separately), and are individually controlled by a

device integral control and a network common

communication. The system is capable of

operating either as air conditioning or heat pump.

خطاب المنافع مع المقاولCommunicating Benefits with Contractor

When it comes to selling

variable refrigerant flow

(VRF) technology, one

of the first things

contractors need to do is

determine when and

where the technology

should be applied

without infringing on

what fits other systems.

خطاب المنافع مع الزبون المحتملCommunicating Benefits with Client

From the consumer’s

point of view, perhaps the

most important benefit of

VRF is its energy-

efficiency savings

potential. However, there

are numerous

advantages of which

consumers may not be

aware, such as:

Space Saving – توفير مساحات

تصميم فعال

EFFICIENT DESIGN Without using large distribution ducts,

the Multi V system removes losses

that are unavoidable in other

systems. In addition, the use of

optimized scroll or rotary

compressors, specially designed heat

exchangers, and inverter technology,

the Multi V system minimizes energy

consumption to levels previously

unattainable by non-VRF systems.

The modular design offers comfort on

demand allowing the choice to use

the system only in the zones where it

is needed further promoting reduced

energy consumption.

No Ducting or Minimum Ducting

إصدار فواتير –تمثيل الكهرباء

ENERGY MODELING-METERING All VRF/VRV Systems are equipped

with building energy simulation software

which is approved by the California

Energy Commission and can be used

for documentation with the California

Title 24 Standards as well as energy

codes throughout the United States

including ASHRAE 90.1 and LEED®.

The software accurately models energy

consumption based on building design,

orientation, location, and other design

conditions taking into account your

specific utility rate structure.

توفير تكييف مناطقي فعال

INDEPENDENT ZONE CONTROL

The VRF/VRV system offers independent

zone control as per occupants desire, from

cooling at one zone while heating anther

zones.

التحكم المريح بتشغيل الضواغط لتحقيق الراحة

COMFORT CONTROL With the use of inverters and dual compressor outdoor units, the

VRF/VRV system offers superior load matching, preventing

constant cycling or large temperature swings. Tight temperature

control through precise load matching ensures maximum comfort,

efficient operation, and superior dehumidification.

تكثيف رطوبة مستمر بسبب إستمرار عملية التبريدDEHUMIDIFICATION WITH COOLING With the use of inverters and dual compressor outdoor

units, the VRF/VRV system offers superior load

matching, allowing unit to process dehumidification

because of continues cooling operation along with part

load adjustment.

STYLISH DESIGN -تصاميم جذابة

Multi V indoor units are available in a wide range of styles to fit

any interior design. With indoor unit choices including cassettes

that mount flush to the ceiling, ducted units that hide completely

concealed in the ceiling, and mirror finished wall mounted units

that fit into any décor, the VRF/VRV system offers unparalleled

aesthetic design.

ENERGY SAVING - توفير الطاقة

The modular design of

VRF/VRV results in

superior energy savings

giving occupants the

choice to air condition or

heat only the zones in use.

The VRF/VRV offers

individual zoning to ensure

occupants comfort.

SUSTAINABILITY -اإلستدامة

The architectural and

engineering community is

adopting a balanced design

approach that considers energy

and water consumption,

repetitive maintenance costs, the

impact of development on the

environment, and the building’s

initial cost as equally important

factors in developing high

performance, sustainable

buildings that will increase

building value. VRF/VRV

systems help achieve points for

sustainability programs

If one of the unit in a multiple outdoor system

malfunctions, the other outdoor units provide emergency

operation*2 for a limited time to facilitate repairs.

For systems composed of two or more outdoor units

Sound Pressure Level مستوى الصوت

Night Time Quiet Operation

This function allows the user to reduce the operational noise of the outdoor

system during night time operations in three distinct steps:

Step 1: Reduces the noise level from 58dBA to 55dBA



QUIET-الهدوء Work without distraction. Sleep

without noise. With indoor units

that can operate at sound

levels as low as 23dB(A) and

outdoor units that operate as

low as 50dB(A) and lower with

night quiet operation, Multi V

creates a comfortable

environment so quiet it’s almost

undetectable. For additional

sound level control, a night

quiet mode can be set to limit

fan speed during off peak

hours.
