We'll begin with the cool, liquid refrigerant entering the indoor coil, operating as the evaporator during cooling. As its name implies, refrigerant in the evaporator &quot;evaporates.&quot; Upon entering the evaporator, the liquid refrigerant's temperature is between 40 and 50°F and without changing its temperature; it absorbs heat as it changes state from a liquid to a vapor. The heat comes from the warm, moist room air blown across the evaporator coil. As it passes over the cool coil, it gives up some of its heat and moisture may condense from it. The cooler, drier room air is re-circulated by a blower into the space to be cooled. The vapor refrigerant now moves into the compressor, which is basically a pump that raises the pressure so it will move through the system. Once it passes through the compressor, the refrigerant is said to be on the &quot;high&quot; side of the system. Like anything that is put under pressure, the increased pressure from the compressor causes the temperature of the refrigerant to rise. As it leaves the compressor, the refrigerant is a hot vapor, roughly 120 to 140°F. It now flows into the refrigerant-to-water heat exchanger, operating as the condenser during cooling. Again, as the name suggests, the refrigerant condenses here. As it condenses, it gives up heat to the loop, which is circulated by a pump. The loop water is able to pick up heat from the coils because it is still cooler than the 120-degree coils. As the refrigerant leaves the condenser, it is cooler, but still under pressure provided by the compressor. It then reaches the expansion valve. The expansion valve allows the high-pressure refrigerant to &quot;flash&quot; through becoming a lower pressure, cooled liquid. When pressure is reduced, as with spraying an aerosol can or a fire extinguisher, it cools. The cycle is complete as the cool, liquid refrigerant re-enters the evaporator to pick up room heat
ITS HERE WHERE THE OIL ATTACHES TO THE TUBES AND BUILDS LAYERS, IMPEDING THE HEAT TRANSFER ABILITY. FRIGI-TECH BONDS TO THE METAL REPLACING THE OIL AND SENDS IT BACK TO THE LUBRICATING CYCLE. THE AMOUNT OF FRIGI-TECH IS UNMEASURABLE BY MECANICAL MEANSS THUS DOES NOT IMPED THE HEAT TRANSFER ONCE ATTACHED TO THE TUBES.

The ASTM Falex Test utilizes an unhardened roller bearing as a brake against a motor driven spinning disk. The force required to stop the disk is a measure of the coefficient of friction, and the amount of bearing damage is a measure of the anti-wear characteristics. The test results showed that when 5% Frigi-Tech Refrigeration Oil Supplement was added to the refrigeration oil, the amount of force required to stop the disk increased dramatically
Despite the fact that this higher braking force was exerted 10 times longer than the dry test, or the pure oil test, the amount of bearing wear damage was significantly less when Frigi-Tech was added.
The length of time that the bomb pressure is above 100 psi is a measure of the oil’s stability and resistance to oxidation. The ASTM Rotating Bomb Oxidation Test results (shown below in Figure 7) reveal that oil treated with Frigi-Tech maintains its oxidation resistance 3 times longer than untreated refrigeration oil does.
