Fact Sheets > Efficiency Enhancement Using Dry-Pak®
Proven Efficiency with Dry-Pak®
The proven efficiency enhancement obtained with Dry-Pak® in compressive refrigerant systems, commonly employed in air conditioning and refrigeration systems has been well documented.
The common results of a 10% ENERGY REDUCTION associated with Dry-Pak® use in these systems can be attributed to two different chemical reactions that occur within the unit. The first most apparent reaction of the dialkoxy component of the Dry-Pak® with the moisture present in the compressive system. The REACTION OCCURS:
- RAPIDLY
- COMPLETELY
- IRREVERSIBLY
This produces inert siloxane materials which are COMPATIBLE with lubricants in the system. The presence of the silane component provides for removal of water and maintains an anhydrous system. The elimination of the water, with its high heat of VAPORATION and which functions as a non-condensable gas, greatly improves the efficiency of the system. Removal of water also serves to increase the life of a compressive system by eliminating acid formation. The other reaction which occurs in the system centers on the unique ability of silanes to PERMANENTLY AND COVALENTLY BOND TO METAL SURFACES. This well documented phenomenon is used throughout the microelectronics and plastics industries.
In a refrigeration or air conditioning system the oil lubricant is transported throughout the system by the rapid movement of the refrigerant. In the evaporator and heat exchanging portions of the systems, the lubricant is attached to the polar metal surfaces and forms a thin film. The oil film acts as insulative layer which restricts heat transfer, thereby decreasing efficiency of the system.
Adding Dry-Pak® 5 Degrees Plus Colder
The addition of Dry-Pak® allows the active silane components to disperse throughout the system. The silane rapidly penetrates the insulative oil layer to react permanently with the metal surface. This reaction reduces energy of the metal and eliminates the electrostatic forces that hold the oil film to the surface. The passivated metal surfaces do not therefore, have the capability to attract the oil, which then freely moves through the system to return to the compressor unit. Elimination of the insulating organic oil layer, therefore, permits more rapid and higher heat transfer IMPROVING THE EFFICIENCY OF THE SYSTEM. This is reflected in the average 5 degree + temperature drop obtained with the use of Dry-Pak®.
Summary
The addition of Dry-Pak® to compressive refrigeration systems IMPROVES EFFICIENCY by removal of water from the system and by passivating metal surfaces to remove insulative lubricant films.
