The primary purpose of the metering device on an air conditioner is to regulate the flow of refrigerant into the evaporator coil. It ensures that the right amount of refrigerant is released to absorb heat from the indoor air, facilitating efficient cooling. By controlling the refrigerant flow, the metering device helps maintain optimal pressure and temperature within the system, enhancing overall performance and energy efficiency.
The primary function of the evaporator in a refrigeration system is to absorb heat from the surroundings, causing the refrigerant to evaporate and cool down the space or substance being refrigerated.
Refrigerant compaticilty is about suiting the refrigerant to your refrigerant system. Every cooling system has refrigerant in it which depends on the type of system you use. If the refrigerant not matches with your system, it wont work. This is refrigerant compatibility.
Evaporation is the primary principle. The three primary components of most residential air conditioners are: # Compressor # Condenser # Evaporator As the refrigerant is compressed in the compressor, lowering the temperatures required to change from liquid to gas and gas to liquid. This is an exothermic, or heat generating, process. The compressed refrigerant, still under pressure, passes through the condenser. For residential systems, this is the "fan in a box" part of the air conditioning system outside. The condenser is actually blowing heat away from the refrigerant. Because the refrigerant is pressurized, the temperature is low enough for the refrigerant to turn liquid. The evaporator is where the cooling actually happens. When the pressure is reduced, the refrigerant evaporates; it turns from liquid to gas. Evaporation is an endothermic, or heat absorbing, process. The refrigerant absorbs heat from the air around it. This leaves the air around the evaporator much cooler and ready to be blown into the house. (Most refrigerators operate using the same process.)
Disposable refrigerant containers are only used for virgin refrigerant.

The type of refrigerant that an E 34 needs is R12 refrigerant. It is absolutely necessary that you do not put any other type of refrigerant into a R12.
You cool it and run it through a metering devise.
In an air conditioning unit, a thermal expansion valve (TXV) operates under three primary pressures: the high-side pressure, which is the refrigerant pressure after it leaves the condenser; the low-side pressure, which is the refrigerant pressure before it enters the evaporator; and the bulb pressure, which is created by the refrigerant in the sensing bulb attached to the TXV. The TXV modulates the flow of refrigerant into the evaporator based on the bulb pressure, ensuring optimal cooling efficiency by maintaining the correct superheat level.
