What an air handling unit is?

Air handling unit commonly named as AHU or air handler is a marvelous equipment that handles air the way a building needs. Commonly made with light weight profiles for sturdy structure. They comprises of filter section, coil section and fan motor section.

They collects the air from outside ambient or from room, clean the air though filtration process, cool the air through coil cooling process and supply the temperature and humidity controlled air in to the room for comfort.

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.

Posted by   | March 7, 2021

Did you know that your HVAC system affects your indoor air quality?

Most of the time, your heating and cooling system benefits your home’s air quality and removes airborne particles.

We at Finpower Aircon LLC, sense everyone’s mindset on the current globally affected Covid19 pandemic and all the life changing events that are occurring due to this epidemic. Working from home, caring for your loved ones, stocking up things, Kids online classes gobble a great deal of time and energy.

With all these things going around, it’s quite obvious to forget your cooling and heating system and the importance to keep it in a good working environment before summer hits.

How Does Your Air Conditioning and Indoor Air Quality Connect?

You may wonder what the connection is between your air conditioning system and the quality of your indoor air. All heating, ventilation, and air conditioning (HVAC) systems use an air filter to remove a wide variety of particles that naturally end up in our indoor air.

A quality cooling system will help to regulate the relative humidity inside your Round Rock home, which helps improve the air you breathe. Moreover, Poor humidity, whether it’s too high or too low, can lead to the presence of mold, mildew, fungus, bacteria, and viruses.

Other related systems and technologies such as air purification systems and the condition and cleanliness of your air duct system can also affect your indoor air quality.

Causes of Poor Indoor Air Quality

We are all aware that outdoor air quality has a great impact on our overall health. What we don’t realize is that the level of pollution inside our homes and offices are so much higher than the outdoors.

We spend 90% of our time indoors, as a result, indoor air quality is worse than it is outdoors.

Indoor sources:

  • Human or Animal Activities – dead skin, hair, viruses or others
  • Cigarette Smoke
  • Dust
  • Bacteria
  • Mold

Outdoor Sources:

  • Pollen
  • Dust
  • Ventilation
  • Airflow Patterns
  • Air Filtration

How to Improve Air Quality?

Comfort: Breathing clean air is one of the joys of life and is certainly a major health benefit. Hence clean air delivered at the right humidity and in the right place is a perfect foundation for optimal comfort.

Demand Control Ventilation | Finpower Aircon

Posted by   | March 7, 2021

Save Energy without compromising your Comfort & Indoor Climate

Finpower’s Demand Control Ventilation (DCV) is a HVAC control system which is regarded as the most efficient way to balance indoor air quality with energy savings. The concept of demand controlled ventilation rests on the principle of providing occupants with the right amount of fresh air, when they need it, where it is useful. With intelligent airflow management (included demand controlled ventilation), energy savings are made on every occasion that the need for ventilation is low or null, which can represent more than half the time. Conversely, an activity that emits indoor air pollution such as preparation in a kitchen, a shower, or even the release of odorous metabolic compounds, generates a need for a greater ventilation to remove the pollution quickly.  Air inlets supply fresh air to rooms like bedrooms and living rooms & extract grilles take air away from wet rooms like bathrooms and kitchens. Fan is that which exhausts the extracted air out of the building.

At every moment, demand controlled ventilation offers an optimization of heating consumption and indoor air quality, on a fully automated basis. Ventilation system is designed on this concept of DCV, which beyond being particularly effective for the comfort of the occupant, has many other benefits.

Better air renewal for greater comfort by providing the ventilation for the places that need the most. When a main room is occupied, its relative humidity increases; the air inlets then open more to increase airflow and better evacuate stale air. Activity in wet rooms (kitchen, bathroom, toilets, etc.) is accompanied by water vapor emissions; the opening of the exhaust units increases with the relative humidity, increasing the airflow and so evacuating polluted air more rapidly.

The higher relative humidity generated by breathing and human activity in the kitchen or shower, for example, can lead to destructive condensation, in which molds can grow. When the relative humidity increases dangerously, humidity sensitive exhaust units open quickly to evacuate excess moisture and eliminate the risk of condensation.
