Fan motor section at the end of the unit is drawing this air through the duct. This is then supplying the controlled air in to the rooms or the area where it is to be served.

These units are normally placed inside a mechanical room or on the roof .Placement is often based on the space availability as these are comparatively larger units when compared to small standard room cooling units. These units are customized and tailor made as per the building requirements. These are provided with special accessories based on custom design like heaters, UV lamps, humidifier, heat pipes etc.

Working mechanism of air handling unit

A simple mechanism in which a filter section, coil section and fan motor section is there. Air is drawn through filter, cooling coil and then supplied through the duct to serving area. Filter section cleans the impurities in air, cooling coil which is mechanically bonded copper tube and aluminum fins cools the air, sometime provided with heater for reheating based on the temperature needed.

Do we need an air handler !!

Indoor air quality is must these days for human to live a comfortable life. Compared to other smaller units, this units gives us the flexibility of choosing wide range of airflow and capacity to cool or heat for any sized commercial residential building. This can be made as a combination to work with chilled water cooling or refrigerant based cooling mechanism.

As it’s always placed in mechanical room or roof tops, easy to access and clean to upkeep the maintenance. Reduced cost when compared to placing multiple small units to cool a particular area. Maintenance on multiple units is more when compared to maintenance on one large indoor unit

Careful selection of air handling unit

If the unit is not well designed understanding the load and application that could be a waste of money and energy. It is also recommended to have multiple unit so that in case one unit is failed, end user expecting the comfort should not be effected.

Application of air handling units

AHU’s are commonly used in commercial and industrial buildings, such as office buildings, hospitals, schools, Shopping malls, and manufacturing facilities. They play a critical role in maintaining indoor air quality and ensuring the comfort and health of building occupants

Main use of air handling units !!

The main use of an air handling unit (AHU) is to regulate and circulate air within a building to maintain a comfortable and healthy indoor environment. They are commonly used in commercial and industrial buildings, such as office buildings, hospitals, schools, and manufacturing facilities. They serve several important functions, including:

Heating and cooling: Air handler can include heating and cooling elements that help to regulate the temperature of the air being circulated throughout the building.

Humidity control: They can also include humidifiers and dehumidifiers that help to regulate the humidity levels in the building.

Air filtration: They typically include filters that remove dust, pollen, and other airborne contaminants from the air being circulated, improving indoor air quality.

Ventilation: They can also include provisions for bringing in fresh outdoor air to replace stale indoor air, improving overall air quality and promoting occupant health.

Overall, the use of an Air handling unit is critical for maintaining a comfortable and healthy indoor environment, improving indoor air quality, and ensuring the safety and well-being of building occupants.

Air handling units use a chiller or Condensing unit or VRF as heat source equipment and exchange heat between chilled/heated water or refrigerant and air to adjust the air temperature. Therefore, air handling units offer excellent operational flexibility. For example, medium-/large-size buildings can be installed with a combination of chillers and AHU’s, while small-/medium-size buildings can use a combination of VRF‘s and AHU’s.

Differences between air handling unit and fan coil unit

In a sense, air handling units are installed for the purpose of cooling/heating the entire building, but fan coils are used for cooling/heating individual rooms. Fan coil units also require a heat source medium.

Generally, heated/chilled water serves as a heat medium for fan coil units (FCU). Water heated or chilled from another location is sent to the fan coil unit for use in providing warm/cool air to the rooms.

Fan coil unit also come with accessories as option based on the design. Some fan coil units are provided with heater banks before or after the cooling coil based on the purpose of sensible heating or de humidification purpose.

Some designs demands for UV in front of the coil at discharge side to eliminate pathogens especially where the air is been served to sensitive areas like laboratory, hospitals rooms etc.

Differences between air handling unit and Fresh air handling unit

A Fresh Air Handling Unit (FAHU) is a type of AHU that is specifically designed to bring in and condition fresh outside air. It is typically used in buildings where there is a high demand for fresh air, such as hospitals, laboratories, or other commercial / residential buildings where indoor air quality is of utmost importance.

Unlike a regular AHU, a FAHU does not recirculate air within the building. Instead, it pulls in fresh outside air, filters it, and then conditions it before distributing it to various parts of the building. There are several options of energy saving with heat recovery wheel and de humidification and RH factor maintenance by heat pipe.

In summary, the main difference between an AHU and a FAHU is the source of the air they handle. While an AHU can handle both fresh outside air and recirculated air from within the building, a FAHU is specifically designed to handle only fresh outside air.

Installation Recommendations for Fresh Air Handling Unit(FAHU): Select a location that is convenient and safe for installation and subsequent maintenance work. This includes replacing all internal components around the unit (e.g. removing heat exchange coils, filters, etc.).

Installation Recommendations for DX Condensing Units: Please follow the recommendation to avoid performance drop. Ensure the list of materials received in the project. FAHU, number of CDU as per the agreed capacity, VFD starter panel with logic sequence been programmed in controller.

Particular attention should be paid to the location of the condensing unit with respect to structures, obstructions, other units, and other factors that may affect airflow. If possible, it should not completely cover the top of the device. However, if it must be placed under an obstacle in a vertical position, a distance of at least 1.5 meters should be maintained between the top of the device and the obstacle. The specified dimensions meet the requirements for air circulation only. Please refer to applicable regulatory requirements before confirming clearance.

Notes on connections to be taken into consideration

Place the equipment on a solid and smooth surface with proper vibration Arrestance. Units to be ideally placed where dust and debris are not sucked by the condenser coil

Hot Air: Open to air till 3 mtr all around.
Intake: Hot discharge from CDU’s not to pass through FAHU intake.
Pipe sizes mentioned in the CDU datasheet are for a 15 mtr distance, if exceed, Kindly contact the manufacturer or representative.
The suction line is to be properly insulated.
The condensing unit is not to be placed directly near the suction of the FAHUs. The approximate distance of 6 meters is to be maintained between FAHU and condensing units.
The condensing units are not to be installed in an enclosed area or a well-like structure leading to short cycling of the exhaust air from the condensing unit. Wall and metal louvers forms as wall to be maintained with 1.5 mtr and condensing units to another unit to be maintained with 3 mtr distance.
All the fresh air handling units are to be installed with sand trap louvers or cowls.
The maximum operating temp for proposed CDUs is 52° C.
Always direct torch flame away from valve body when brazing and wrap expansion valve body with a wet rag.
Valves may be installed in any position but should be located as close as possible to the distributor or evaporator inlet.
Attach the remote bulb to the suction line as close to the evaporator outlet as possible on a horizontal run. Position the bulb at the 3 or 4 o’clock position. Clean the surface of the suction line where the remote bulb is to be attached, and then securely fasten the bulb with the straps provided.
Connect one end of the external equalizer line to the valve. Connect the other end to the suction line slightly downstream from the remote bulb location and position so that it cannot siphon oil from the suction line.

Condensing Units / Air-Cooled Condenser

Firstly Finpower manufactured – Air-cooled condensers / Condensing Units use ambient air in order to cool and cycle refrigerant. Secondly, these can often be seen outdoors, as they are commonly used in exterior units in residential and rooftop cooling systems. Thirdly, and most importantly, the condensing unit manufactured by Finpower is a key component of all vapor compression systems.

The condenser is an important component of any vapor compression system. In a typical refrigerant condenser, the refrigerant enters the condenser in a superheated state. It is first de-superheated and then condensed by rejecting heat to an external medium. The refrigerant may leave the condenser as a saturated or a sub-cooled liquid, depending upon the temperature of the external medium and design of the condenser.

Why Air-cooled condensing unit?

Availability of air is in plenty.
Disposal of warm air is not a problem.
Simple in construction, as there are no pipes required for air.
The fouling of the condenser is small.
The maintenance cost is low.

What makes Finpower condensing unit?

Compressor: Single or Dual Hermetic sealed scroll compressors are used due to the high efficiency, which results from higher compression achieved at a lower rate of leakage.
