Types of HVAC systems.
HVAC units have various types. Each system is designed for specific purposes and environments. Here are some common types:
- Split System: This system has components inside and outside the building. It comprises an indoor unit (containing the evaporator coil and blower) and an outdoor unit. (housing the compressor and condenser coil). This system is widely used in residential and small commercial spaces.
- Packaged System: In a packaged system, all components—compressor, condenser, evaporator, and often the heating elements—are housed in a single unit. It is commonly used in small commercial buildings or residential applications with limited space.
- Ductless Mini-Split System: These systems have one outdoor compressor and condenser unit and one or more indoor air-handling units mounted on walls or ceilings. They’re ideal for areas where ductwork could be more practical and possible.
- Heat Pump System: Heat pumps provide heating and cooling by transferring foam between the indoor and outdoor air. They’re efficient in moderate climates but might require a supplementary heating source in colder regions.
- Geothermal System: These systems utilise the earth’s stable temperature for heating and cooling. They involve a loop system buried underground to exchange heat with the planet.
- Variable Refrigerant Flow (VRF) System: VRF uses refrigerant gas as a cooling and heating medium. They offer zoning and individual temperature control by adjusting refrigerant flow to indoor units.
- Chilled Water Systems: Commonly used in more extensive commercial or industrial settings, these systems circulate chilled water through a network of pipes to provide cooling.
- Hybrid System: Combining multiple technologies, such as a heat pump with a gas furnace, a hybrid system optimises energy efficiency by switching between the most efficient sources based on conditions.
- Evaporative Coolers: They are also known as swamp coolers. These units use the evaporation of water to cool and humidify the air. They’re suitable for dry climates.
- Portable Units: These are standalone units used for temporary or spot cooling/heating, often in areas where a permanent unit system isn’t feasible.
Each unit type has advantages and is suitable for specific applications, building sizes, climates, and efficiency requirements. The system choice depends on factors like space, budget, temperature, and the intended use of the building or space.
In Heating, Ventilation, and Air Conditioning, FAHU stands for “Fresh Air Handling Unit .” It’s an air-handling unit containing a fan and a coil. The fan is responsible for moving air through the unit. At the same time, the coil helps heat or cool the air, depending on the system’s requirements. FAHUs are commonly used in various air conditioning systems to regulate air temperature and circulation in buildings.
Types of FAHU units.
Fresh Air Handling Units come in different configurations and types, each tailored for specific air conditioning applications. Here are some common types of FAHUs:
- Horizontal : These units are designed to be installed horizontally, usually in false or above suspended ceilings. They’re suitable for spaces where vertical installation isn’t feasible or space constraints exist.
- Vertical : Vertical FAHUs are installed vertically and are often used in spaces like mechanical rooms, basements, or areas with ample vertical space.
- Ceiling Concealed : These units are concealed above the ceiling, keeping them out of sight and providing a more aesthetically pleasing appearance. They’re commonly used in commercial spaces where maintaining a clean, uncluttered look is essential.
- Floor Mounted : It is Installed on the floor; these units are suitable for spaces where ceiling or wall installation could be more practical. We can easily access these types of units for maintenance and service.
- Modular : Modular FAHUs offer flexibility in terms of capacity. We can customise it by adding or removing modules based on the space’s specific needs. They’re adaptable to changing requirements and space limitations.
- High Static Pressure : These units are designed to handle higher air pressures where air needs to be pushed through long duct runs or where increased resistance is present.
- Low Profile : Low-profile FAHUs are designed to fit in spaces with limited vertical clearance. They have a smaller height profile while still offering efficient air-handling capabilities.
- Hydronic : These units incorporate hydronic coils for heating or cooling. Water is used in these types of units as the heat transfer medium. They’re often part of systems that utilise hot or chilled water from a central source.
- Fresh Air Handling Units with Heat Recovery: Some FAHUs have heat recovery capabilities that can recover and reuse heat from the exhaust air, improving energy efficiency.
FAHUs are adaptable units that offer flexibility in terms of installation, capacity, and functionality. Choosing the correct type of FAHU depends on factors such as the available space, specific air conditioning requirements, building layout, and desired performance characteristics for heating, cooling, and air distribution.

An air handler unit (AHU) is a critical component of your air conditioning system. It is used for circulating air throughout your home. It is typically located inside the house, either in a closet, attic, or basement. It works with an air conditioner or heat pump to distribute conditioned air.
An air handler pulls in air from your home through a return duct, passes it through a filter to remove dust or debris, etc and then pushes it through a series of coils. These coils are either heated or cooled up on seasonal requirements, and the air is then distributed through your home via a network of ducts.
The air handler also contains a blower motor responsible for pushing the air through the system. This motor can be adjusted to control the speed of the air, allowing for more precise temperature control.

How to Choose the Right Air Handler unit ?
When choosing the correct air handler for your home, there are a few key factors to consider. These include your home’s size, budget, and specific heating and cooling needs.
- Size: The size of your air handler is an important consideration, as it needs to be able to circulate air throughout your home effectively. If your air handler is too small, it will have to work continuously to keep the area at a comfortable temperature, resulting in higher energy bills. On the other hand, if your air handler is too large, it may start and stop more frequently, leading to increased energy costs. We suggest consulting a professional technician to determine the correct air handler size for your home. They can assess your home’s size and layout and recommend the appropriate size air handler for your needs.
- Budget: Air handlers come at various prices. Hence, we advise you to consider your budget and requirements when choosing the right one for your home. While opting for a cheaper option may be tempting, remember that a higher-quality air handler may save you money in the long run through increased energy efficiency and fewer maintenance costs.
- Heating and Cooling Needs: It’s essential to consider your specific heating and cooling needs when choosing an air handler. If you live in a colder climate, you may opt for an air handler with a more powerful blower motor to ensure your home stays warm during winter. On the other hand, if you live in a warmer climate, consider prioritizing energy efficiency to keep your cooling costs down.
Chilled Water Pumps with VFD Control Panels.
As a leading HVAC contractors in UAE, we have various chilled water pump solutions with different pumping configurations. The pump speed can vary depending on the number of chillers, the cooling loads, and the outside temperature. Generally, the large units come with end suction or horizontal split casing pumps. Its running speed depends on various factors. These water pumps have different flow capacities. When the pump runs through a VFD, it controls the exact flow requirements by varying the speed.
How does a VFD benefit in chilled water circulation system?
A Variable Frequency Drive can offer several benefits in a chilled water circulation system:
- Energy Savings: VFDs can adjust the speed of the motor driving the circulation pump based on the actual demand for cooling. By matching the pump speed to the required flow rate, it help save energy compared to traditional constant-speed pumps, which run at a fixed speed regardless of the load.
