How many types of refrigerants are there?

However, there isn’t just one type of refrigerant, which makes it easy to get them confused. There are actually three different types, and using the wrong one can damage your air conditioner because they’re not interchangeable. With that in mind, it’s important to know as much as possible about these refrigerants.

What is a CFC refrigerant?

CFC Refrigerant: CFC refers to the chemical composition of the refrigerant. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115.

What are the most commonly used refrigerants?

The most common type of refrigerants used today across the world are hydrofluorocarbons (HFCs). Previously, chlorofluorocarbons (CFCs) were more widely used, but were phased out following the introduction of the Montreal Protocol in 1987.

What are Group 2 refrigerants?

Class 2 is for refrigerants that, when tested, exhibit flame propagation at 140°F (60°C) and 14.7 psia (101.3 kPa), have a heat of combustion less than 19,000 kJ/kg (8,174 British thermal units BTU/lb), and have a lower flammability limit (LFL) greater than 0.10 kg/m3.

What are the four types of refrigerant?

Types of Refrigerants
  • Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect. …
  • Hydrochlorofluorocarbons (HCFCs), including R22. …
  • Hydrofluorocarbons (HFCs), including R410A and R134.

What is a refrigerant name three refrigerants in common use?

What are the 3 main types of refrigeration systems that are used in commercial building HVAC systems?

Three of the most commonly used systems for commercial buildings are: Variable-air-volume (VAV) systems with a packaged rooftop unit. Chiller, cooling tower and boiler systems. Water-source heat pump systems with a cooling tower and boiler.

What are the main components of refrigeration system?

The 4 Main Refrigeration Cycle Components
  • The compressor.
  • The condenser.
  • The expansion device.
  • The evaporator.

What is R600a refrigerant?

R600a is an HFC-free refrigerant with no ozone depletion potential and a lower global warming potential compared to earlier refrigerants. … GE Appliances, a Haier company has been transitioning to environmentally friendly refrigerants in household refrigerators and freezers.

What are the different types of commercial HVAC systems?

Types of Commercial HVAC Systems
  • Single-Split System. At the more modest end of commercial cooling budgets, single-split system AC is ideal for cafes, shops, small offices and similar cozy spaces. …
  • Multi-Split System. Multiple indoor units connect to a single, larger outdoor unit. …
  • VRF or VRV System. …
  • VAV or CAV System.

What are the different types of HVAC systems?

There are four main types of HVAC systems. There are split systems, hybrid systems, duct-free systems, and packaged heating and air systems. Each of these types of HVAC units have pro’s and con’s, and knowing these factors can help you decide which is best for you.

What are the different types of commercial heating systems?

Different Types Of Commercial Heating Systems
  • Oil Or Gas Steam Heating Systems. The oil or gas steam heating system is one of the oldest ways to provide central heating to a commercial property. …
  • Gas Or Oil Water Heating Systems. …
  • Natural Energy Systems. …
  • Heat Pump Systems.

What is a VRV system?

The Daikin VRV system is a multi-split type air conditioner for commercial buildings that uses variable refrigerant flow control developed by Daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building.

What is BCU HVAC?

Fan Coils (FCU) and Blower Coils (BCU) – A terminal unit which is capable of providing heating and/or cooling to a zone or a space. Ventilation air is typically provided by a dedicated outside air system which supplies outside air directly to the room or to the return ductwork in a ducted system.

What is the difference between residential and commercial HVAC?

Residential HVAC systems are typically single, stand-alone units that are often located in the backyard or against the side of a house. Commercial HVAC systems are much larger than residential systems. This makes sense because commercial buildings require more power and energy to heat and cool a larger facility.

What is AHU and FCU?

AHU and FCU are both included in the HVAC system. … AHUs are usually connected to a central HVAC system whereas an FCU can function or be installed itself. Because of this, it is often the AHU that is used to ventilate an entire building whereas FCUs are used in smaller and often local spaces only.

What is a chiller system?

What Is a Chiller? An industrial chiller is a refrigeration system used to lower the temperature of machinery, industrial spaces, and process fluids by removing heat from the system and transferring it somewhere else.

What is the cassette AC?

A ceiling cassette air conditioning unit is no different and works on exactly the same principles; these units work the same way as wall-hung split system units. … The indoor unit itself sits flush to the ceiling and distributes conditioned air through two, three or four sides of the unit.
