SEMINOLE CASINO PROJECT

*VRV/VRF Home
*Installation
*Seminole Casino Project

The Seminole Tribe of Florida has been a valued customer of Commercial Cool Temp Corp. for many years. We have had the oppertunity to provide our services to the Seminole Classic Casino in Hollywood Florida.

One of our key HVAC installation for the casino has been two projects involving the Mitsubishi VRF CITYMULTI installation.


The energy efficient City Multi VRF range features unique 2-pipe technology that provides simultaneous heating and cooling. Up to 60 indoor units can connect to a single heat recovery outdoor unit. Heat recovery systems 22 – 90 kW; Heat pump systems 10 kW – 140 kW.


Mitsubishi Electric Cooling and Heating Solutions promotes

environmental awareness not only by putting innovative

technology to work for you, but also in the products themselves

of the design and manufacture for example:


• Eco-friendly refrigerant: Environmentally-friendly R410A

refrigerant offers zero Ozone Depletion Potential (ODP)

and allows for higher heat transfer coefficient (COP). This

innovative feature means a reduction in equipment size,

a reduction in piping size and higher pressure for greater

performance. Smaller equipment also means less impact

on the environment at the end of the product’s life cycle.


• Standard compliance: All Mitsubishi Electric products

follow standards and guidelines as set forth by the

ENERGY STAR®, EPA, AHRI, ASHRAE, UL, ETL and ISO.


• Recycling design: Our air conditioners are specially designed

to allow for easy cleaning, efficient disassembly and more

practical recycling. The number of parts used in indoor units

has been reduced by adopting modular components, a process

which also simplifies materials separation for recycling.


• Minimal impact on landfills: All air-conditioning products

use long-life washable filters rather than disposable filters.

To date, as much as 89.8 percent of the materials used to

build a standard CITY MULTI system component are recyclable.


• Smart energy usage: Mitsubishi Electric INVERTER zoning

systems smartly deliver only the amount of capacity needed–

unlike a typical full-power ON system. Individual indoor air

handlers are installed each zone. These air handlers

measure the load for each zone and deliver only the

capacity needed directly there, reducing energy costs

from long duct runs. Smarter sensing technology and

microprocessors enhance the system’s ability to accurately

measure room temperature for added comfort, performance

and efficiency.


CITY MULTI is the first two-pipe, simultaneous cooling and

heating system available in the United States and around the

world. Our technology has a long and proven track record of

quality and reliability. Mitsubishi Electric, an acknowledged

global industry leader, has installed CITY MULTI zoning systems

in buildings throughout Asia, Europe, and other countries for

nearly 30 years with great success and customer satisfaction.

Let a Mitsubishi Electric representative show you how you can

put the ultimate cooling and heating system to work for you and

your customers right here, right now.

The best way to ensure total comfort for the occupants of

offices, schools, hospitals, assisted-living facilities, hotels and

other is to provide each individual zone with a personalized

comfort system. Zoning offers maximum individual comfort and

energy savings because each zone receives conditioning only when

it needs it. Each zone of the CITY MULTI system has its own

indoor unit or group of indoor units that precisely control the

indoor temperature, while operating with minimal energy usage.

You set the comfort level, then relax.

The CITY MULTI VRF (Variable Refrigerant Flow Zoning) system

takes advantage of INVERTER technology by varying the speed

of the compressor in the outdoor unit to meet the changing load

requirements in each of the indoor zones.


A CITY MULTI VRF system consists of an outdoor unit, a

branch circuit (BC) Controller (depending on series), multiple

indoor units, and corresponding system and zone controllers.

Installing this fully integrated zoning system is fairly simple.

A single outdoor modular unit or combined modular units, the

BC Controller, and each of the indoor units are connected by

a two-pipe refrigerant system. The outdoor unit and the BC

Controller, depending on the series, work in unison to

deliver the required refrigerant flow to each indoor unit. The

Direct Digital Controls (DDC) system controls the network link

between the indoor units with the BC Controller and the

outdoor unit to provide convenient control of the entire

system. Separate remote controllers connected to individual

indoor units – or groups of indoor units – provide

individual zone control. These controllers provide a wide variety

of configuration settings to satisfy each zone’s requirements,

including temperature control and timer settings.

CITY MULTI VRF systems provide the flexibility to meet any

application, ranging from the simple to the complex. CITY

MULTI R2, Y, and W-Series systems, available in 208/230V

and 460V capabilities, can be designed for up to 50 zones

per system. The 208/230 V single phase S-Series system can

be configured for up to eight zones. Systems with Mitsubishi

Electric Hyper-Heating INVERTER (H2i™) have the capability to

connect with up to 24 indoor units. With 11 different indoor unit

styles, providing both ducted and ductless offerings, the CITY

MULTI VRF system is ideal for any type of application.

Multiple CITY MULTI systems can be integrated into our

controls network to manage up to 2,000 zones from a single

networked PC using Mitsubishi Electric furnished software.


The CITY MULTI technology is designed to

allow building owners and designers as many

opportunities as possible to attain Leadership

in Energy and Environmental Design (LEED®) points when

designing and applying CITY MULTI. Mitsubishi Electric is a

corporate member of U.S. Green Building Council (USGBC)

and is committed to sustainable products and design.

CITY MULTI VRF technology may contribute to a building

receiving LEED points in areas of Energy and Atmosphere

and Indoor Air Quality


CITY MULTI is designed to provide the quietest possible

operation for both indoor and outdoor environments. Indoor

units operate as low as 24 dB(A), and outdoor units operate as

low as 58 dB(A). That’s a major benefit, especially for hospitals,

other health care facilities, schools, and libraries. CITY MULTI

dependably provides comfortable cooling and heating

all year long.
