Things You should Know About Heating Ventilation and Air Conditioning (HVAC)

HVAC Air Conditioning

According to American Society of Heating, Refrigeration, and Air Conditioning Engineers(ASHRAE), a HVAC system should heat, cool, clean, ventilate, humidify and dehumidify the air. A sound HVAC system provides thermal control and indoor comfort, and the one that is based on the principle of thermodynamics, fluid mechanics, and heat transfer. 

Hamilton Air Conditioning aims to bring you the air conditioning solution from installation to maintenance and repair to ventilation that fits your needs and brings you a step closer to a healthier environment.

We know heating and cooling are an essential part of air conditioning in our homes and most industrial units, but what fails to understand is HVAC’s meaning, which gets ignorant most of the time. Here you can find about different types of air conditioning units.

What is Heating, Ventilation, and Air Conditioning (HVAC)?

Whether it is an industrial unit, home, schools, or sizeable interior environment, quality air is essential. Heating, ventilation, and air conditioning systems provide acceptable indoor air quality through filtered ventilation.

HVAC systems help in controlling temperature, humidity, and air quality to provide a comfortable indoor environment.

In HVAC Systems:

  • With the use of radiators or supply air systems, the air is heating
  • By extracting polluted air from the space and maintaining clean air, ventilation is accomplished
  • Air conditioning lowers the temperature and carries humidity levels using air cooling and water cooling systems.

Different types of HVAC systems

Split HVAC System

Packaged HVAC System

Ductless HVAC System

Components of this air conditioning system are deployed in different places

This air conditioning system is available in single unit

This air conditioning system is deployed to be used in smaller space

Split System

A split system air conditioning unit is where the key components are separated. These components are deployed in different places. They come in two other forms: mini-split and the central system.

A central HVAC system is a duct system that provides multi-zone temperature control capability. They are single system air conditioners. They use water as a cooling medium in them and use ductwork for air distribution. The only disadvantage that comes with these systems is that they are expensive to install. They can be switched off when no one is using the space and saves up on the costs.

Ductless Systems are designed to operate in small spaces and are deployed in a single room. They require minimal wall space, a compressor, and heat exchanger unit. These systems are easy to install in both homes and as internal units. The downside of these systems is, they are much costlier. 

Packaged

Packaged systems are used in buildings. Packaged heating systems and air conditioning systems are available in a single unit. A packaged heating system contains:

  • Heat pump and evaporator together in one unit
  • Thermostat interface for controlling the system
  • Optional air quality improves like air purifiers, cleaners, ventilators, or UV lamps

There are two types of packaged air conditioners:

  • Packaged air conditioners with water-cooled condensers

These air conditioners are cooled with water coolers. Water is continuously supplied for the air conditioners to keep working. They are the primary air conditioning systems and are used mostly inside the buildings.

  • Packaged air conditioners with air-cooled condensers 

These air conditioners are cooled using atmospheric air. They use a fan that sucks in air and blows the air into the condenser coil. These air conditioners work smoothly with no use of water and do not need maintenance. They are suitably used as outdoor units.

You can choose any of the HVAC systems that fits your needs from air conditioning company London.

Heating Systems

 How to select HVAC equipment?

Our air conditioning needs depend on three main factors: heating, cooling, and ventilation. To select suitable HVAC equipment, we need to look at these factors:

  • Heating and cooling needs
  • Energy efficiency
  • Indoor air quality
  • Humidity control
  • Outdoor air quantity and quality
  • Potential for natural ventilation

Ventilation Cleaning

Ventilation cleaning is vital to experience good air quality from time to time. With air pollution and dust around, the air conditioners get stuck with dirt. Due to this, they can stop working and get damaged. For this, ventilation cleaning and maintenance is essential.

A proper ventilation cleaning method uses negative pressure technology.

Heat Recovery Ventilators transfer heating or cooling from stale exhaust air from sand to provide fresh air. This ventilation aims to remove moisture and contaminants while conserving the energy.

According to the Australian government’s website, 15-20% of heat loss from buildings is caused by leakage of air.

Ventilation installation provides freshness into your space by cutting the stale air, consisting of carbon dioxide and creating an unhealthy environment. When stale air enters the room, opening windows to let the stale air pass out is the easiest option. But at times, this natural ventilation is not sufficient as it unseals the amount of fresh air present in the room. That is why you need a ventilation installation in place.

For this, Heat Recovery Ventilators (HRVs) are a perfect solution that allows fresh air into your room and blocks the stale air. Heat Recovery Ventilators transfer heating or cooling from stale exhaust air from sand to provide fresh air. This ventilation aims to remove moisture and contaminants while conserving the energy.

How does Heat Recovery Ventilation Work?

Heat Recovery Ventilation works on two ducts: one that runs stale air and another that runs fresh air. An airstream called a heat exchanger runs through the device, which converts the outcoming stale air into the fresh air and blocks the mixing of the two different airstreams.

To get a heat recovery ventilator for your home or office, you need to have excellent insulation to get the most out of the Heat Recovery Ventilation unit. If you wish to install the HRV, you need to ensure that your home or space does not have any air leakage, as these ventilators work the best in areas where there is no air leakage.

Before installing the HRV, make sure to patch up all the cracks and gaps. It is an excellent option to incorporate these ventilators in low air leakage buildings. At Hamilton Air Conditioning, we give you a suitable tailored solution for ventilation services. You can book from our expert range of ventilation services as per your requirement.

You know, HVAC systems are essential for a healthy and energy efficient space. You can now install the right system from the three standard HVAC systems: packaged, centralized, and ductless. Hamilton Air Conditioning is one such air conditioning company London that provides you a one-stop solution for all your air conditioning needs.
