[RebeccaDella]

There are two common weights of refrigerants available in the market: 250g and 300g. Generally, mid-to-low-end vehicles require about 3-4 bottles, while high-end vehicles may need approximately 4-6 bottles. Below is some relevant information about refrigerants: 1. Definition: Refrigerant, also known as coolant or refrigerant gas, is the medium substance used in various heat engines to facilitate energy conversion. These substances typically undergo reversible phase changes (such as gas-liquid phase transitions) to increase power output, like steam in steam engines or refrigerant in refrigeration systems. 2. Classification: Inorganic compounds, organic compounds, and mixed working fluids.
