because black body absorbs/emit maximum heat
To charge a semi-hermetic compressor with refrigerant, you will need to connect a refrigerant cylinder to the system using proper hoses and gauges. Then, you will slowly introduce the refrigerant into the system while monitoring the system pressure and temperature. It is important to follow the manufacturer's guidelines and recommendations for the specific type of refrigerant and the correct amount to be added.
Hermetic compressors rely on refrigerant gas for cooling. When drawing deep vacuums during the recycling or recovery process, there may not be enough refrigerant gas circulating to adequately cool down the compressor. This can lead to overheating of the compressor and potential damage to the equipment.
Technically, black is the absence of color. When light is absorbed and no color is reflected, we perceive it as black. In terms of pigment, black is a color that can be created by combining various pigments together.
Is black the absence of color? Well, the answer is all in perspective. In light Black is the absence of color and white is the essence of color, but in paint black is the essence of all color and white is the absence of color.
In the most simplistic sense the color GRAY is 50% Black & 50% White. Thereby, making the color GRAY equally close to BOTH the Color WHITE and the Color BLACK.

Hermetic manufactured from special materials because Hermetic compressor motor materials must be compatible with the refrigerant and oil circulating in the system.

In a hermetic compressor, the internal overload protector is typically located on the compressor's start winding terminal. This overload device is designed to interrupt the electrical current if the compressor overheats, helping to prevent damage from excessive temperature. It ensures the compressor operates safely and efficiently.
In a typical hermetic compressor, the compressor unit is securely mounted inside a welded or bolted shell to ensure a sealed environment. It is usually positioned on vibration dampening mounts or pads to minimize noise and vibration transmission. The electrical motor and compressor assembly are often integrated as a single unit, with the motor driving the compressor's piston or scroll mechanism directly. This design helps maintain the integrity of the hermetic seal, preventing refrigerant leaks.
because the hermatic compressor motor must be compatible with the refrigerant and oil circulating in the system.
the compressor capacity will increase
A hermetic compressor typically has three terminals: one for the start winding, one for the run winding, and one for the common connection. These terminals are used to connect the compressor to the power supply and control circuitry. In some cases, there may also be an additional terminal for grounding. The specific configuration can vary depending on the compressor design and application.
The parts of a hermetic (sealed) reciprocating compressor is as follows; motor, crankshaft, bearings, valves, and pressure relief valve and piston(s). there are other smaller parts that can be named but these are the main players. The hermetic scroll compressor is a little different than the reciprocating compressor because it uses an orbiting scroll and a stationary scroll to compress the refrigerant instead of pistons. This is why a scroll compressor cannot run "backwards". The scroll compressor also has an oil pick up tube which differs from a reciprocating compressor. Now a "semi-hermetic" compressor is build like a small engine. It has an oil pump, reed valve plate, unloaders, pistons, bearings, etc. A screw compressor is in a class all to itself.

No the compressors in residential condensing units are called hermetic compressors and have to be rebuilt by cutting open the compressor shell, then rebuild the compressor and then weld the shell shut. Buy a new compressor or condensing unit.
