Oriental Instruments & Dongyi Technology
Refrigerant charging machines are used in industries such as air conditioning, refrigerators (cabinets), water dispensers, and automotive air conditioning; the specially developed power supply is applied to vacuum equipment and charging equipment, such as coating machines, high vacuum exhaust equipment, and electric vehicle charging stations.
What methods are there for charging refrigerant?
Refrigerant is the medium used for cooling operations in machines and equipment such as air conditioners. If the refrigerant leaks or is insufficient, the cooling effect will be significantly reduced.

The role of adding refrigerant to the air conditioner
Freon is the medium for transferring heat in air conditioning refrigeration systems. Without it, heat cannot be effectively exchanged. Air conditioning cannot cool or heat.

What is refrigerant? How many types of refrigerants are there?
What is refrigerant? Refrigerant is the medium used to complete energy conversion in various heat engines, and it is also the working fluid that completes the thermodynamic cycle in refrigeration machines. When machines operate, they emit heat, and refrigerants can absorb heat from the cooled objects at low temperatures and then transfer it to cooling water or air at higher temperatures. Generally speaking, refrigerants are required to have excellent thermodynamic properties, specifically including: a critical temperature higher than the condensation temperature, a saturation pressure corresponding to the condensation temperature that is not too high, a low standard boiling point, a small specific heat capacity, a low adiabatic index, a large heat quantity per unit volume, a high heat transfer coefficient, low viscosity, small density, and chemical stability.
