Centrifugal Compressor and Rotary Compressor is preferred with refrigerant R-113.
The Reciprocating compressors is the type of compressor that is preferred with refrigerant R-113.
Put a dye type refrigerant and watch for leaks at fittings, hoses, and compressor Put a dye type refrigerant and watch for leaks at fittings, hoses, and compressor Put a dye type refrigerant and watch for leaks at fittings, hoses, and compressor Put a dye type refrigerant and watch for leaks at fittings, hoses, and compressor
Your condensor outside , where the compressor is . should have an information plate showing the type of refrigerant used
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.
If you have a scroll type compressor, at shutdown the compressor stops pumping and the hi & lo refrigerant pressures equalize, breifly spinning the compressor backwards until they are fully equal. This is normal for these type compressors.
Look for a label on the underside of the hood, around the radiator crossover, or the compressor. The label will tell you the type and quantity of refrigerant, and also the type of refrigerant oil used in the system.
To calculate the size of a compressor in refrigeration, you need to consider factors such as the refrigeration load (heat to be removed), desired temperature range, type of refrigerant, and efficiency of the compressor. Use the formula: Q = m * Cp * ΔT, where Q is the cooling capacity, m is the mass flow rate of refrigerant, Cp is the specific heat of the refrigerant, and ΔT is the temperature difference. You can then select a compressor with a capacity equal to or greater than the calculated cooling capacity.
Generally, because something is wrong with it. Maybe a bearing went out, maybe the compressor is just worn, maybe it was damaged because of a refrigerant overcharge, compressor oil overcharge, or the wrong type of compressor oil used. Could be a number of reasons.
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
Look on the outdoor compressor, there should be a sticker that tells you what kind of refrigerant it uses. If it says r22, it is the old type.
A fridge typically uses electrical energy to operate. The electricity powers the compressor, which circulates the refrigerant to cool the interior of the fridge.
Your 1990 has R12 refrigerant in it which isn't available anymore at parts stores. To add refrigerant to your vehicle you will have to get the a/c system vaccuumed and retrofitted to accept new r134a refrigerant and pag100 compressor oil. You can take it to a shop to get it vaccuumed and retrofit it yourself with kits from your local Autozone. -broncomudder89
