[Product efficacy 1, to improve vehicle air-conditioning cooling effect, you can make the air conditioning vent temperature within 1 minute average reduction of 3-5 ℃. 2, to reduce compressor load by 15% to 23%, reduce engine power loss caused due to the air conditioning operation, keeping power output of the engine. 3, improve the fuel consumption due to air conditioning operation due to increased fuel savings of 10%. 4, reduce noise, eliminate the vehicle due to the air conditioning operation due to jitter. 5, to improve the durability of car air conditioners, prolong compressor life 2-4 times. [Product Mechanism: 1, air-conditioning treasure for the US high-tech nanotechnology products, by increasing the surface lubricity automotive air conditioning compressor parts, reduce wear air-conditioning compressor. 2, using its nanostructure and a lose-lose theory, the formation of both oleophobic and hydrophobic double thinning effect in the wall. 3, increasing the closed compressor, improve work efficiency. Air conditioning treasure is evenly distributed by the diameter of only a few nanometers synthetic hydrocarbon particles, under pressure and temperature, these particles can gradually fill the pit friction surface, so that the formation of a new surface roughness increased from micron to the nanoscale, thereby greatly reducing the friction coefficient, reducing leakage, improve the work efficiency of the compressor. Air conditioning Bao nanoparticles to accumulate sediments and frozen film on the wall, with a suspension of the role of the dirt from the wall gradually stripped dissolved. After a period of self-cleaning, the heat exchange efficiency of the air conditioner has been greatly improved. Bao is compatible with a variety of air-conditioning refrigerant oil and a variety of refrigerant F12, F22, R134a, etc., will not produce any insoluble precipitate of the product, not on the components and materials of the refrigeration system to generate any corrosion. So air conditioning is an excellent treasure first compressor protection agents, but also the effect of significant repair agent. Which reduce energy consumption, reduce failures, extend compressor life is very good. It can be widely used in central air conditioning, refrigerator, home air conditioners, vehicle air-conditioning and all kinds of refrigeration equipment. Usage and dosage] 1, add 1 bottle of vehicles a year, operated by professionals. 2, adding step: # Check the device to ensure the air conditioning system does not leak, and the air-conditioning system should be the normal range of refrigerant and compressor lubricant. # Start the engine, turn on the air conditioning switch, and adjust the air conditioning switch open to the maximum. # The thermometer placed in the air conditioning vent, the air conditioning vent temperature to be reduced to a minimum, observe and record lowest temperature. # To a head with the low-pressure compressor of a special tool port (L shown) connected to the other end with the "air-conditioning treasure" tank connection ("air-conditioning treasure" pot need upside down), and rotate to ensure no leakage during the addition. # Clockwise rotation with the "air-conditioning treasure" handle special tool body connection, so special tools small cone to move down until the cone into the cool air of the small treasure pot, then rotate the handle counterclockwise, to observe special tools connecting pipe, can be observed, "air-conditioning treasure" of the compressor filling process, while observing the temperature changes, to be added to "air-conditioning treasure" down to the outlet when the new minimum temperature, do some comparison. # Remove the special tool, and check the low pressure port for leaks.
