Difference Between AHU and HVAC • Categorized under Miscellaneous | Difference Between AHU and HVAC What are AHU and HVAC? AHU, which is Air Handling Unit is an appliance used to circulate air. HVAC is Heating, Ventilating and Air Conditioning system. HVAC is the central unit to which AHU is connected. AHU is only a part of HVAC and as such there is hardly any difference between then two. HVAC mainly refers to the technology of automotive environmental comfort. The Heating, Ventilating and Air Conditioning system uses the principles of fluid mechanics, thermodynamics and heat transfer. The discoveries of by Michael faraday, Nikolay Lvov, Reuben Trane, William Rankine Wills Carrier, James Joule and Sadi Carnot among others had paved the way for Heating, Ventilating and Air Conditioning system. HVAC comes in medium to large designs. HVAC is used to condition the atmosphere in industrial houses, skyscrapers and aquariums. Air Handling Unit is a large metal box that conditions the air, which helps in creating a perfect atmosphere.

Blower/fan, Heating and/or cooling elements, Filters, Humidifier, Mixing chamber, Heat recovery device, Controls, Vibration isolators are some of the components that make a AHU. Air Handling Unit comes in three types. The Mall air handlers or terminal units are used for local use They mainly consist of coil, air filter and blower. Then there is the Make up Air Unit, which is larger air handler. The third one is the Roof Top Unit, which is mainly used for outdoor use. It is mainly fitted n the roof of a building. As AHU is only part of HVAC, it can be hard to make out a difference between the two. As seen earlier, one system is part of another system and hard to differentiate them. 1. AHU is Air Handling Unit. HVAC is Heating, Ventilating and Air Conditioning system. 2. HVAC is the central unit to which AHU is connected. AHU is only a part of HVAC. 3. HVAC comes in medium to large designs. 4. Air Handling Unit is a large metal box that conditions the air, which helps in creating a perfect atmosphere.

5. Air Handling Unit comes in three types — Mall Air Handlers Make up Air Unit and Roof Top Unit. 6. As AHU is only part of HVAC, it can be hard to make out a difference between the two.

Of course we can’t write about all of the variations in a short blog1 ton split ac delhi post, so we’ll take a look at one of the routineaeon ac units inquiries we see at Service Experts Heating & Air Conditioning: what’s the difference between an airbmw e46 ac control unit An air handler contains the components that move the air throughout your home, called theIt is usually set inside the home and operates with both the heating and cooling components of your HVAC system. If you take a quick look at an air handler, it may closely resemble a furnace. handlers can run with either an air conditioner or a heat pump and contains the indoor coil, used to cool and heat your

home depending on which system it’s running with. Here’s what you should know about air handlers: if you’re searching for a conventional furnace or air conditioner, you’ll likely never need to know what an air handler is because it’s probable you won’t need one. However, if you’re in the market for an electric heat pump, it’s helpful to know that an air handler will probably be a part of your home’s HVAC system. Air conditioners contain the condenser and are traditionally set outside the home. One of the most common confusions with air conditioners is that they cool the existing air in your home. Air conditioners actually pull out heat from inside your home through a host of pieces in your system and expel it outside. The removal of heat is what makes the air feel cool, not the addition of cold air. The warm air inside your home is drawn into the system through return ducts and then go over a refrigerant coil.

As the warm air is blown across the cooled coil,Refrigerant lines then carry the heat outside. Now you’re left with cool, comfortable indoor air that you can enjoy on theAnd that’s pretty much it. Sure, the equipment is more complex than that, but the process itself is easy to break down and comprehend. Understanding all of your home’s heating and cooling parts for the your city climate is probably a little unrealistic, but there are a few things that can be helpful to you asIf you’d like more information about your current system and whether an air handler or air conditioner is right for your home, give the experts at Service Experts a call at 866-397-3787 or set up a free appointment online today.< Return to Blog If you’re shopping around for a new central air conditioner for your home, you’ve probably seen that there are two main types: But do you know which one your home has or why? In this blog you’ll learn: The differences between these two systems

The pros and cons of each How to know which one fits your home’s needs Split air conditioning system What it is: In a split-system central air conditioner there are two parts an outdoor metal cabinet and an indoor cabinet. That’s why it’s called a “split” system. The outdoor cabinet contains the condenser and compressor and typically sits on a concrete slab outside your home. The indoor cabinet contains the evaporator and is usually located in the attic or a closet. The indoor cabinet also typically includes a furnace (or the inside part of a heat pump). The indoor and outdoor units are connected by a refrigerant line. Here’s a simple diagram of a split system: Greater energy efficiency possibilities - Split air conditioning systems have SEER ratings from 13 to 23. Labor costs - Labor costs more because you are installing a unit outside the house and also inside (usually in the attic or crawlspace, depending on the type of air handler).

Also, the system can’t be charged with refrigerant until it has been set in place, which adds to the cost. When you’d want this: It’s a more cost efficient choice if your home already has a furnace, and you are purchasing a new air conditioning unit or replacing an older unit. Learn more about this on Energy.gov’s website. Packaged air conditioning system What it is: The evaporator, condenser, and compressor are all located in one cabinet and thus “packaged” together. This single cabinet is usually placed on a roof. Some packaged air conditioners can include electric heating coils or a natural gas furnace. That means you won’t need a separate furnace inside. Space efficiency - Unlike split-system units, the package unit has all the components in one place. Cheaper installation - Since packaged units can come pre-charged with refrigerant, and they are only installed outside, installation is cheaper than a split unit. Limited energy efficiency: Packaged units typically have a SEER rating from 10 to 18.
