Fan Coil Units

A fan coil unit is simply a device consists of heating and cooling oil. Fan coil units traditionally contain their own thermostat so it can cool itself down when it gets to hot. The fan coil works by cooling the air in the room side unit and absorbing the heat energy by the refrigerant. The refrigerant is then pumped as gas in lines to the external condenser. The Condenser cools the refrigerant by drawing air across the coil and condensing it into liquid.Due to their simplicity, fan coil units are more economical to install than ducted or central heating systems with air handling units. However, they can be noisy because the fan is within the same space.

However I am sure you guys have heard about Air Handling Unit (AHU) also. AHU is basically referred to as a generic term for anything or any device which is involved in the transportation, heating or cooling of air. After the heating or cooling of the air, the air stream is moved forward or directed to the required placed through air ducts which include rooftop units and furnaces. But there a petite difference between AHU and FCU. The fan coil units are smaller and self-contained than the AHU's. And the major difference between AHU and FCU lies in the fact that in FCU's there is no ducting involved for the movement of air. In the FCU's the fan in the internal section of the FCU carries out the function of moving the air over a heated or cooled coil and then directly moving out the air into the surrounding air without the use of any ducts. The FCU's can also be used in the case of water also where as AHU's deal with air only. 

Gulf Airconditioning Manufacturing Industries (GAMI) is one of the largest manufacturer and distributor of Fan Coil Units in the middle-east. They are the leading manufacturing and distributors in various product like AIR COOLED SCREW CHILLER , MODULAR AHU  , MONOBLOCK AHU , PACKAGED AC  , FAN COIL UNIT. They are ISO 9001-2008, ISO 14001-2004 & OHSAS 18001-2007 Certified Company for quality, health, safety and environment management programs.GAMI is a member of GIBCA Group of Companies.

GAMI manufactures high quality, efficient and technically advanced Chilled Water and packaged airConditioning equipment for GCC & international markets.

The FCU in GAMI is made from 1.0 mm thick galvanized (G90) Steel sheet. It has a Drain Pan also made from 1.0 mm thick galvanized (G90) Steel sheet, polyester powder coated for corrosion resistance.

The cooling coil is separately designed for standard/district cooling chilled water Applications. The Fan is centrifugal double inlet double width, forward curved, balanced to avoid noise and increase efficiency.

The Fan motors are provided with 5 speeds. Factory pre-selected and pre-wired to the terminal block fr 3 speeds – high, medium, low. The best part is the air filter which is designed havefactry installed permanent and washable aluminium filters.

Packaged Air Conditioners

The window and split air conditioners are usually used for the small air conditioning capacities up to 5 tons. The central air conditioning systems are used for where the cooling loads extend beyond 20 tons. The packaged air conditioners are used for the cooling capacities in between these two extremes. The packaged air conditioners are available in the fixed rated capacities of 3, 5, 7, 10 and 15 tons. These units are used commonly in places like restaurants, telephone exchanges, homes, small halls, etc.

As the name implies, in the packaged air conditioners all the important components of the air conditioners are enclosed in a single casing like window AC. Thus the compressor, cooling coil, air handling unit and the air filter are all housed in a single casing and assembled at the factory location.

Depending on the type of the cooling system used in these systems, the packaged air conditioners are divided into two types: ones with water cooled condenser and the ones with air cooled condensers. Both these systems have been described below:

Packaged Air Conditioners with Water Cooled Condenser

In these packaged air conditions the condenser is cooled by the water. The condenser is of shell and tube type, with refrigerant flowing along the tube side and the cooling water flowing along the shell side. The water has to be supplied continuously in these systems to maintain functioning of the air conditioning system.

Packaged Air Conditioners with Air Cooled Condensers

In this packaged air conditioners the condenser of the refrigeration system is cooled by the atmospheric air. There is an outdoor unit that comprises of the important components like the compressor, condenser and in some cases the expansion valve (refer the figure below). The outdoor unit can be kept on the terrace or any other open place where the free flow of the atmospheric air is available. The fan located inside this unit sucks the outside air and blows it over the condenser coil cooling it in the process. The condenser coil is made up of several turns of the copper tubing and it is finned externally. The packaged ACs with the air cooled condensers are used more commonly than the ones with water cooled condensers since air is freely available it is difficult maintain continuous flow of the water.

The cooling unit comprising of the expansion valve, evaporator, the air handling blower and the filter are located on the floor or hanged to the ceiling. The ducts coming from the cooling unit are connected to the various rooms that are to be cooled.

 Both these above mentioned product are manufactured and distributed at Gulf Air-conditioning Manufacturing Industries (GAMI). They are the leading manufacturers and distributors in various product like AIR COOLED SCREW CHILLER, MODULAR AHU  , MONOBLOCK AHU , PACKAGED AC , FAN COIL UNIT.It is an ISO 9001-2008, ISO 14001-2004 & OHSAS 18001-2007Certified Company for quality, health, safety and environment management programs.GAMI is a member of GIBCA Group of Companies.GAMI manufactures high quality, efficient and technically advanced Chilled Water and packaged air Conditioning equipment for GCC & international markets.
