HVAC (heating, ventilation, air conditioning) are the mechanical systems providing thermic comfort for residents accompanied by indoor air quality and air conditioning. These arrangements are designed to achieve environmental requirements. HVAC include various heating equipment, ventilation equipment, and cooling or air-conditioning equipment. These systems are used for residential as well as commercial needs. The outdoor air is drawn into the space depending upon the area’s outdoor conditions. Then later, the air is heated or cooled before being distributed into the occupied zones. Which HVAC system to choose for a particular building depends upon numerous factors like:
- The climate of the place
- Design of the building
- How Old The Building is
- Personal Preferences Of The Owner
- Project Budget
There are 4 Common Types Of HVAC unit systems used chiefly everywhere. Have a look.
Heating and cooling split systems
As the name suggests, it is divided into two separate units. One provides the purpose of heating, and the other is for cooling. This one is the most common. They come with easily identified indoor and outdoor units connected with copper tubing. A heat drain or air ventilator is installed outside the premises paired with a gas furnace or a fan coil. The cooling units use compressors, refrigerants and loops to cool air and a fan to keep the hot air. They are run during the summer season.
For heating panels, heaters are mostly placed underground like a basement and other storage space that uses gas to warm up the slack. A thermostat device is used to control the temperature and humidity of the place. The split system of these heating and cooling products is for homes with ample indoor space.
Boilers are the fundamental part of the heating system of the space. It is an enclosed container having liquid, mainly water. An external energy source heats the liquid in the boiler and distributes the steam or hot water throughout the applied area. This hot water heating system pumps actual warm or hot water to the radiators. Steam boilers convert water into steam first and distribute it later.
Duct free (Mini split)
Ductless or duct-free split systems use small air handlers located in specific areas to heat or cool that particular space. Heating and cooling systems contain an outdoor condensing unit paired with multiple indoor units. It allows for energy conservation by focusing only on those areas that need cooling or heating and is a cost-effective feature. A ductless system is an excellent alternative to the existing ducted HVAC systems. It is an appropriate choice for hotels or venues, allowing guests to control the individual temperature.
Packaged heating and air conditioning system
The packaged HVAC unit comprises all system parts in one metal cabinet. The evaporator coil, condenser, and compressor are all housed together to save space from being used inside. The cabinet is placed mainly on a building’s ceiling or a cement slab outside the home. The outdoor cabinet is connected to all the other rooms through ductwork. Some packaged central air systems include a natural gas furnace or electric heating coils. It is a suitable option for space deficient houses due to its compact size.
Crucial HVAC system requirements:
- The products and devices should be of high quality and serve good value.
- They should be durable and easy to maintain.
- Skilled and licensed technicians should appropriately install the system panels safely.
- The HVAC maintenance services providers must provide quality repair and replacements.
- The company should give a good warranty on supplies.
- HVAC systems should be energy-saving, cutting hydro and gas bills.
