Energy-saving synergist being helpful to improvement of refrigeration effect of automobile air conditioner

Abstract

The invention relates to an energy-saving synergist being helpful to improvement of the refrigeration effect of an automobile air conditioner and a preparation method for the energy-saving synergist. The energy-saving synergist is prepared from two parts of substances, wherein the first part comprises the following components in parts by weight: 20-40 parts of Militec-1, 0.5-1.0 part of 4,4-dioctylphenylamine, 1.0-2.0 parts of triphenyl phosphate, 1.0-2.0 parts of N-phenyl-1-naphthylamine and 60-80 parts of trimethylolpropane fatty acid ester; the second part comprises R124a. Through the adoption of the energy-saving synergist, not only can pipelines and a compressor be cleaned, but also the abraded parts of the compressor can be effectively repaired, so that the sealing property of the compressor can be greatly improved, and the original effect of the automobile air conditioner can be realized again.

Description

technical field [0001] The invention relates to the technical field of air-conditioning system maintenance, in particular to an energy-saving synergist and a preparation method for enhancing the cooling effect of automobile air-conditioning. Background technique [0002] Due to various reasons, the refrigeration efficiency of automobile air conditioners will drop by 8% in one year, and will drop by 25% in two years. [0003] To solve the problem of declining refrigeration efficiency of automobile air conditioners, the methods generally adopted are (1) clearing the dust accumulation in the condenser and evaporator; (2) replenishing the leaked refrigerant. [0004] By cleaning the accumulated dust and adding refrigerant, the cooling effect of the air conditioner will be improved to a certain extent, but it still cannot completely solve the problem of the decline in the cooling efficiency of the air conditioner. That's because with the use of the air conditioner, the refrigera...

AI Technical Summary

Problems solved by technology

[0003] To solve the problem of the decline in the cooling efficiency of automobile air conditioners, the general method is to (1) remove the dust accumulated in the condenser and the evaporator; (2) supplement the leaked refrigerant

[0004] By cleaning the accumulated dust and adding refrigerant, the cooling effect of the air conditioner will be improved to a certain extent, but it still cannot completely solve the problem of the decline in the cooling efficiency of the air conditioner

That's because with the use of the air conditioner, the refrigerated oil will adhere to the condenser, evaporator and other pipes, and at the same time, mechanical wear will cause the sealing of the compressor to deteriorate, resulting in a decrease in the cooling efficiency of the air conditioner.

[0005] The operation of the air conditioner compressor must use lubricating oil, that is, refrigerating oil. On the one hand, the existence of refrigerating oil lubricates the mechanical part to reduce wear, but the wear is also inevitable; on the other hand, it will have adverse effects. A small amount of refrigerating oil Into the circulation pipeline and adhere to the inner wall of the pipeline, the refrigerated oil adhered to the condenser, evaporator and other pipelines has poor thermal conductivity, which greatly reduces the heat exchange performance, the condenser cannot dissipate heat well and the evaporator cannot If the strong cold air is output, the air conditioning effect will be reduced

Moreover, these oil stains exist in the pipes, and it is almost impossible for us to remove them. As time goes by, the oil stains accumulate thicker and thicker, and the cooling effect of the air conditioner becomes worse and worse.
