What are HFC refrigerants?

What are HFC refrigerants?

HFC Refrigerant: HFC refers to the chemical composition of the refrigerant. Hydrofluorocarbon indicates that the refrigerant is comprised of Hydrogen, Fluorine, and Carbon. Common HFC refrigerants are R-32, R- 125, R134a, R-143a, and R-152a. A blend that contains different HFCs is considered an HFC refrigerant.

What are the two 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 Tu HVAC?

Abbreviated TU. thermal zone. An individual space or group of neighboring indoor spaces that the HVAC designer expects will have similar thermal loads. Building codes may require zoning to save energy in commercial buildings.

Is R-410A A HFC?

R-410A is a member of the hydrofluorocarbon (HFC) class of refrigerants and is composed of equal parts R-32 and R-125.

What is primary and secondary refrigerant?

Primary Refrigerants: When used in compression or absorption systems, these fluids provide refrigeration by undergoing a phase change process in the evaporator. As the name implies, secondary refrigerants are those liquids, which are used for transporting thermal energy from one location to other.

What are the five classifications of refrigerant?

In the following section, different groups of refrigerants are discussed, some examples are given and their fields of application are described.

  • CFC = ChloroFluoroCarbons.
  • HCFC = HydroChloroFluoroCarbons.
  • HFC = HydroFluoroCarbons.
  • FC = FluoroCarbons.
  • HC = HydroCarbons.
  • NH3 = Ammonia.
  • CO2 = Carbon Dioxide.
  • Summary Table.

How many types of refrigerant 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.

What is SF in HVAC?

SF – Square Feet, Service factor. SFD – Combination Smoke / Fire Damper. SHC – Sensible Heat Capacity.
