What is R152A refrigerant and how does it work?
R152A refrigerant, also known as difluoroethane, is a hydrofluorocarbon (HFC) used primarily in refrigeration and air conditioning systems. It has a low global warming potential and serves as a suitable alternative to other refrigerants that contribute to ozone depletion. R152A operates by absorbing heat from the environment and releasing it in a different location, which is the core principle of refrigeration.
When R152A is cycled through an evaporator, it absorbs heat from its surroundings, causing it to evaporate into vapor. This vapor is then compressed and condensed back into a liquid, expelling the absorbed heat in the process. The cycle repeats as the refrigerant continuously circulates through the system, providing the cooling effect needed in various applications.
