Heating, Ventilation & Air Conditioning

HVAC: Heating, Ventilation and Air Conditioning

HVAC usually refers to the mechanical system that provides heating, ventilation and/or cooling within a residential or commercial building or a premise. HVAC full form is Heating, Ventilation and Air Conditioning. It refers to the various systems, which are used for the movement of air between indoor and outdoor areas. These systems help keep you fresh in the summers while keeping you away from the cold in winters.

HVAC Meaning

Now, you must be thinking about “What is HVAC?”. An HVAC system is designed to control the environment in which it functions. HVAC system does this by controlling the air cleanliness of the air in that environment. HVAC full form is Heating, Ventilation and Air Conditioning. These systems are becoming popular in new construction as these HVAC systems uses fresh air from outdoors to provide high quality fresh air indoors.

Ventilation in this process helps in replacing the air within the space and ensures a better quality of air indoors. The HVAC system helps in providing good quality air by removing all the moisture, heat, dust, bacteria (airborne), CO2, among some other gases. Now that we are aware of What is HVAC, let’s understand how HVAC systems work.

What does an HVAC System comprises of?

An HVAC system comprises of:

Air Handling Units – with forward and backward fans duly tested

Motors and Electrical – Suitable Motors for AHU Handling

Electrical Paneling and Wiring – complete with all control

Insulation – Ducting / Pipes using Neoprene or APO

Chillers – Water Cooled or Air Cooled as per requirements

BMS System – High-end in-built BMS system to improve the overall energy efficiency, controls, monitoring, performance.

Best Quality Standards – All equipment are validated and shipped prior to dispatch with DQ,IQ,PQ,OQ as per GMP STD

How Does HVAC Work?

There are multiple components which are combined together to make an HVAC system work. Several users combine systems like central heating and AC systems to use one blower. The single blower helps in thecirculation of air using the ducting in a home or office. On the contrary, the blower can also circulate air with a ductless system for different rooms in the house or various zones in an office.
Following are some of the most important parts, which are kept at work to make the best HVAC system and provide best clean room atmosphere:

Air Return – Air Return part marks the beginning of the ventilation process. The return helps in the suction of air, process it through a filter and then draws it into the main HVAC system

Filter – The next part in the HVAC system process is the filter. The air is processed and filtered through this part for purification. It is always advisable to clean filters at regular intervals to keep the HVAC system just as new

Exhaust Outlets – Exhaust outlets helps to turf out the exhaust, which is created by the heating system

Ducts – Be it the heated air or cool air, Ducts act as a channel for the air to pass through. It is always advisable to get the ducts cleaned every 2 to 5 years to keep the HVAC system in the best condition

Outdoor Unit – The outdoor unit of an HVAC system includes a fan, which provides help in air flow. It is always advisable to keep the outdoor unit clear of any kind of debris

Compressor – Compressor sits in the outdoor unit of the HVAC system. It helps in the conversion of refrigerant from a gas to liquid and then sends it to the coils of the HVAC system

Coils – Coil is also present in the outdoor unit of the HVAC system. Coil and refrigerant cools down the air and then passes it ahead

Blower – All the warm air from the main section of the HVAC is sucked in by the blower

Types of HVAC Systems?

The most common types of HVAC systems are as follows:

Heat Pump – Heat pumps sucks in heat from a cold space or environment and warms it to release in the room to maintain the temperature

Rooftop Unit – Rooftop HVAC systems are usually preferred to manage the temperature of a large space. It is a large unit which is placed on the rooftop of the building

Water Source Heat Pump – This type of HVAC system is uncommon in today’s time as geothermal HVAC systems are picking up the trend nowadays. The water source heat pump is exactly what the name suggests as they require proximity to a body of water to work

Packaged HVAC – Packaged HVAC systems are similar to the rooftop HVAC systems but are preferred for smaller areas/rooms or domestic use.

Split System HVAC – Split system HVAC means that there are 2 units of the system – outdoor and indoor. There are two types of split system HVAC – ductless and central)

Ductless HVAC – These HVAC systems are the most preferred HVAC systems for a single large room or multiple small rooms.

Which is the Best HVAC System available?

Chempharm India provides the best HVAC system available in the market. You can ASK CHEMPHARM EXPERTS to design a most customized HVAC system as per your requirement and budget. To ensure best quality, Chempharm India incorporates the following key elements: (HVAC SYSTEM FOR CLEAN ROOM)

Clean Room HVAC System – The integrity of the cleanroom environment is created by the pressure differential compared with adjacent areas through air flow pattern.

The HVAC system requirements include:

Supplying airflow in sufficient volume and cleanliness to support the cleanliness rating of the room

Introducing air in a manner to prevent stagnant areas where particles could accumulate

Filtering the outside and re-circulated air across high efficiency particulate air (HEPA) filters

Conditioning the air to meet the cleanroom temperature and humidity requirements

Ensuring enough conditioned makeup air to maintain the specified positive pressurization

Monitoring systems – Monitoring systems include a means of indicating that the cleanroom is functioning properly. The variables monitored are the pressure differential between the outside environment and the cleanroom, temperature, humidity and, in some cases, noise and vibrations. Control data should be recorded on a routine basis.

HVAC System Design for Clean Facility

HVAC systems in cleanrooms are substantially different from their counterparts in commercial buildings in terms of equipment design, system requirements, reliability, size and scale.

A cleanroom differs from a normal comfort air conditioned space, in the following ways:

Increased Air Supply: Whereas comfort air conditioning would require about 2-10 air changes/hr, a typical cleanroom would typically require 30 – 80 air changes and could be as high as 600 for absolute cleanliness.

The use of high efficiency filters: The use of high efficiency particulate air (HEPA) filters having filtration efficiency of 99.9997% down to 0.3 microns is another distinguishing feature of cleanrooms. The HEPA filters for stringent cleanrooms are normally located at the terminal end and in most cases provide 100% ceiling coverage.

De-humidifiers  in few cases would be needed to control RH in the HVAC systems for hygroscopic pharma products or specialized electronic sectors .

Room pressurization: The cleanroom is positively pressurized (to 0.05 in-wc) with respect to the adjacent areas. This is done by supplying more air and extracting less air from the room than is supplied to it.

Frequently Asked Questions (FAQs)

What is the Difference between AC and HVAC?

HVAC full form is Heating, Ventilation and Air Conditioning. Whereas, on the other hand AC refers to Air Conditioning. AC only helps in cooling of the air in your home or office. The most common ACs available are Window AC units, split ACs and centralized AC systems. On the other hand, HVACs comes loaded with heat pumps in addition to the air conditioning units to provide heating and cooling both as per the requirement.

How many years does an HVAC system usually last?

The life of an HVAC system depends on the usage and regular maintenance of the system. But, usually the life of an HVAC system is expected to last 15 to 25 years.

What is the acronym HVAC?

HVAC full form is Heating, Ventilation and Air Conditioning. HVAC system is a mechanical system, which provides heating, ventilation and/or cooling within a building (be it residential or commercial).

What is AHU?

AHU is a central air conditioner station that handles the air that, usually, will be supplied into the buildings by the ventilation ductwork (connected to the AHU). AHU full form is the Air Handling Unit. Basically, AHU meaning is in its name only – Air Handling Unit. Handling the air means that the air will be delivered into the building spaces with thermo-hygrometric and IAQ (Indoor Air Quality) treatment. The accuracy of the treatment will depend on the specificity of each project. This means, the Air Handling Unit treat the air by filtering, cooling and/or heating, humidifying and/or dehumidifying.
