The Working Principle of HVAC Systems


HVAC Systems

HVAC is an abbreviation of Heating, Ventilating, and Air Conditioning. Therefore, HVAC systems are a conditioning air process which includes the process of heating, cooling, humidifying, dehumidifying, cleaning, ventilating, and also air movement. By thus process, the systems of HVAC is sometimes also called by an air controlled system.

All of those functions are working each other. It is because it will determine temperature, and air humidity inside the building, and also providing fumes control, the air pressure inside the building, and providing a fresh air there. For that, to know well about HVAC systems, bellows are the information for you:

Principle of HVAC Systems


This system usually used in many countries which has a cold temperature. HVAC systems are compiled by some important elements like a boiler, furnace, heat pump, radiator, and hydronic.


Ventilating is a process of circulating the air inside with outside the room, which used to remove the dust, humidity, bad smell, carbon dioxide, heat, bacteria of the air, and also to regenerate the fresh air inside the room.
Generally, there are two types of ventilating in HVAC systems, those are forced ventilation and natural ventilation. Forced ventilation usually use a big fan to circulate the air, while natural ventilation does not use it anymore. It is usually performing as a window, which let being opened in a certain room.
For the function, forced ventilation is usually used in the big company, or at home like in the kitchen or bathroom. In the kitchen, it is usually used to suck the smoke from the stove, while in the bathroom used to throw the bad smell around the room.

Air conditioning

Most of the people know well about this unit. We can easily find this HVAC systems in some building like office, home, industrial, etc. It is usually used to make the room for being cool, although the temperature outside is high. This unit is consist of some important parts of refrigerant, compressor, heat exchanger, and also expansion valve.

The used of HVAC in the world of pharmacy

HVAC systems are very vital used in the world of pharmacy, the functions of HVAC there, such as:

  • To reins the temperature
  • To reins the humidity
  • Keep the environment from always being clean
  • To avoid contamination
  • To reins microbe accretion
  • Keep the personal healthy


The HVAC systems usually consist of some following units:

  • Evaporator (is used as heat absorption when the process of evaporation)
  • Blower (is a fan to drain off of the air)
  • Filter (is used to filter the air, so it will become clean)
  • Duct (is an air drain from the room to indoor unit)

The purpose

The purpose of HVAC systems is providing a system as well as the rule of CPOB in order to fulfill the need of product protection and the process is in accordance with the GEP requirement, just like reliability, treatment, continuity, flexibility, and safety.

Well, HVAC systems are nowadays used in many purposed, but it is usually very vital used in the world of pharmacy. There, it used to avoid production of the drug from the danger of contamination, keep the environment from always being clean, and the others.

What is HVAC Tips to Make You Air Conditioner Performs Efficiently

03.-what-is-hvac-1 WHAT IS HVAC TIPS

What Is HVAC

You may wonder what is HVAC? Many homes in our country used HVAC (Heating, Ventilating, and Air Conditioning System) to increase or decrease the temperature to adjust the situation.

This such as device can be unaffordable for middle income and needs a lot of energy to spend. So it’s better to know further about what is HVAC. Since a smart people who own this will get a better experience throughout the usage of this device. And save your money, and of course get your home healthy.

What is HVAC system component?

So, what is HVAC? In the central system of HVAC is a unique, since some elements usually got to be installed outside your home. And some elements got to be installed inside your home. The places that normally get installed inside your home are in the attic, in the basement or even closet. You will find the fireplace (gas, oil, electric) and the portion of evaporator air conditioner. You will also notice the blower that could perform both air conditioner and fireplace? Now you got a glance at what is HVAC system.

Ducts are being attached to the blower, and then the tubes serve as a channel to pass all heated air and cooled air to the entire room of the house. What are HVAC special cases that need to know?

Well, a furnace won’t be necessary if your HVAC system works in pumping heat. An expert explains what is HVAC ‘’ so actually the system is regularly working in the mechanism. It pumps heats and makes the room cooler, and reversely work in the winter to increase the temperature.

Indoor And Outdoor Components

What is HVAC elements to pay attention? Indoor and outdoor components will still be needed in a heat pump system. Compressor and condenser components of the air conditioner are placed outside the house (heat pump) that are installed in a metal with a big fan stick to it.

The packaged system is one of the alternatives to use in a split system, so what is HVAC packaged? Outside the house, all of the components will be installed into one single unit. With ducts passing through the wall of the house.

Now, you know what is HVAC package and how it works, you may see that it could be a better choice for you who want to keep your space open for the new interior and still have the cool and heating equipment. ‘’V’’ installation could be the option for your HVAC.

Experts moody says, ‘’ when indoor air quality is having a great impact in human health problem, so, the systems of mechanical ventilation become more used by the household.  Do you want to know more about ‘’ventilation”? here’s the info.

  1. Heating

    Burning gas and oil in a chamber is the way to put on the fireplace, air is circulated by blower throughout the chamber, and then heat will be absorbed first by air before it flows throughout the house. In term of by products Combustion gases are employed for burning oil and gas, some are lethal. A metal vent the gases to the outdoor, combustion chamber got the air for the fire from a pipe. Conditioned air is pulled from inside the home.
    When the combustion uses air, cold air seeps shell’s building, that makes the building cooler, and better efficiency.

  2. Cooling

    What is HVAC cooling system to achieve efficiency? Cooling is attained via the electric air conditioner, the compressor compresses the refrigerant gas to yield high-pressure gas. This high-pressure gas is pumped by a compressor via radiator similar to a condenser coil of copper, fins, and tubing where the heat is transferred by a large fan to the outdoors. This is all done on the AC equipment. Next, the cooled air gets compressed, it pumps refrigerant liquid into the house through the copper tubing.

    Arriving at evaporator coil. And it will vaporize from a liquid to a gas again. A natural device of this shifts from liquid to gas is that heat is absorbed by refrigerant quickly from the air and blown through evaporators. Cooled air’s circulated throughout the home via the ducts, so what is HVAC cooling mechanism actually generates? The refrigerant head back outside to the compressor, then the cycle starts over and again and again.

  1. Ventilation

    What is HVAC to increase air quality? Based on the EPA, the risk of contamination at indoor air is five times higher than outdoor. As a citizen, we spend 90% of our times indoor.

It’s so simple like a set of ducts with a fan that can that clean the air up indoor and brings fresh from outside. However, it consumes a lot of energy. The newest method to overcome this problem is that use the Heat Energy Ventilator and Energy Recovery Ventilator.

This kind appliances planted to the ducts and make an additional muffler ducts and a supply to the outdoor, and then the unit get ride of dirty air from the room. And bring a healthy air from the outside to the inside. Now you have all explanations of what is HVAC.
