What is Automotive Refrigerant?
2 Answers
Automotive air conditioning refrigerant, also known as automotive refrigerant, is commonly referred to as 'Freon' or 'coolant'. It is categorized into environmentally friendly types (134a) and non-environmentally friendly types (R12, which is rarely used in vehicles). Relevant information about automotive air conditioning filters is as follows: 1. Introduction: An automotive air conditioning filter is a specialized filter designed for air purification inside the vehicle cabin. It uses activated carbon composite filter cloth, which combines highly efficient adsorbent material activated carbon with long-fiber non-woven fabric, featuring a compact structure. 2. Function: It can effectively filter out smoke odors, pollen, dust, harmful gases, and various odors. The filter also efficiently filters and adsorbs particulate impurities, achieving the function of filtering oil and purifying air.
I've been driving for over 30 years, and simply put, refrigerant is the colorless, odorless liquid that circulates in the air conditioning system to cool the car. Its main function is to absorb heat from inside the vehicle and release it outside. It works by evaporating and absorbing heat in the evaporator, then moving to the condenser to release heat, thereby cooling the interior. Common types include the older R134a, while newer models mostly use the more environmentally friendly R1234yf to reduce environmental harm. Last time my AC was cooling slowly, I found it was due to insufficient refrigerant causing unstable pressure, so I immediately had a technician top it up. Don't forget to check the seals during maintenance—regular upkeep can extend its lifespan.
