A method for evaluating the smell of an air conditioner evaporator

Abstract

The invention belongs to the technical field of vehicle indoor air quality testing methods, and in particular relates to an odor testing and evaluation method for an air-conditioning evaporator, comprising the following steps. : Connect the condition parameter test system including ventilation to the port of the air conditioner evaporator; the third step: adjust the control parameters, pass air into the airtight container through the ventilation system, control the wind speed, and open the container when the air is introduced. The process of smelling the odor and recording the odor intensity level, this method considers the material itself, the processing process, and the dynamic combination of the various conditions and parameters of the refrigerant to comprehensively evaluate the odor. From the actual use process temperature and wind speed. Influence, open the air duct system, and evaluate the temperature, opening time, and the comprehensive situation after stable operation and operation. This method will have a wide range of influences in the evaluation of vehicle air quality.

Description

technical field [0001] The invention belongs to the technical field of vehicle indoor air quality testing methods, and provides an odor testing and evaluation method for an air conditioner evaporator. Background technique [0002] With the enhancement of consumers' awareness of environmental protection, the air quality in the car is more and more concerned by consumers. The air pollution in the car mainly comes from benzene series and aldehydes and ketones organic volatiles, nitrogen oxides, carbon monoxide and so on. These pollutants come not only from the outside of the car, but also from the release of the materials in the car itself. Leather, carpets, textiles, plastic products, foamed rubber materials, air conditioning systems, and various additives and fillers added during processing and molding are all carriers of pollutants. Therefore, to prevent air pollution in the car and improve and purify the air quality in the car, it is not only necessary to control the emiss...

AI Technical Summary

Problems solved by technology

The air conditioner evaporator is made of metal and has no odor itself, but the material pollution that may be caused during the production and processing, and the odor change of the evaporator core in the dry and wet state during use make the air conditioner evaporator odor Characteristic evaluation becomes meaningful. However, there are many defects in the existing related technologies. For example, the odor test of the air conditioner evaporator is different from that of general parts and materials. If the general odor test method is adopted, a part of the air conditioner evaporator is taken for odor test In this way, only the metal parts used to prepare the air conditioner evaporator and the odor emitted by the material pollution during the processing can be tested

In the actual use process, the air conditioner evaporator needs to add refrigerant, and then heat up or cool down to diffuse the temperature through the air system, and at the same time spread the smell, so it is not enough to test the smell of the material, and it cannot simulate the actual use. Therefore, it is urgent to develop an odor test evaluation method to solve the above problems
