Scrap identification of air conditioning and ventilation equipment

As a kind of mechanical equipment, air conditioning and ventilation equipment, when its service life is up, no matter how well it is maintained, it is difficult to avoid various failures, which will eventually lead to scrapping.

As an independent third-party appraisal agency under Guoke Holdings, Zhongke Testing has the qualifications for fixed asset scrapping appraisal. It can organize technical personnel to evaluate the assets to be scrapped and evaluate and issue a wind turbine blade scrapping appraisal report based on the list of assets to be scrapped and relevant information provided by the client.

According to the service life standards of the air conditioning industry, air conditioners that have been used for about ten years should be scrapped. If the air conditioner is continued to be used for more than ten years, it will explode, spontaneously ignite, the outdoor unit falls, and the cooling air contains a large number of germs. This type of air conditioner is no longer recommended for use.

Another type is that it can no longer be used after about five years if it is installed in a place with a lot of dust, oily fumes and a harsh environment (containing corrosive substances). The appearance of this type of air conditioner is seriously corroded, the outer shell is yellow, and the cooling fins are rusty. It can be seen that such air conditioners have reached the end of life in advance and cannot be used.

1. Visual inspection: Appearance inspection through direct observation or with the help of simple tools to find obvious defects or abnormalities in the equipment.

2. Non-destructive testing: Using physical properties such as sound, light, and magnetism to detect the interior or surface of the equipment without damaging the equipment.

3. Mechanical property testing: Conduct mechanical property testing on the materials and parts of the equipment to ensure that they meet the design requirements.

4. Functional testing: Simulate or actually run the operation of the device to detect whether its function is normal.

Due to use and safety requirements, a batch of air-conditioning and ventilation equipment in a hotel had to be replaced. In order to determine whether the equipment had reached the scrap state, our company was entrusted to appraise whether the batch of air-conditioning and ventilation equipment had reached the scrap state.

Appraisal analysis results:

Appraisal analysis The expert group conducted on-site inspection and investigation results on the air-conditioning and ventilation equipment commissioned for appraisal, and made the following suggestions and conclusions:

Some of this batch of air-conditioning and ventilation equipment have exceeded their economic life and have lost their use value. Their continued use poses safety and health risks and should be scrapped. The rest of the equipment has been running for a long time and has high damage repair costs, so it is recommended to be scrapped.

1. Equipment list sorting: First, it is necessary to sort out the list of all equipment, including the name, model, specification, quantity, purchase date and other information of the equipment.

2. Equipment condition assessment: Evaluate the condition of the equipment based on its usage and maintenance records. It can be carried out through regular inspections, random inspections, etc.

3. Expert appraisal: For some highly professional equipment, experts in related fields need to be invited for appraisal. Experts can evaluate the condition of the equipment based on its performance testing, technical indicators and other factors.

4. Processing decision making: Based on the identification results of the device, make corresponding processing decisions. If the equipment can be repaired or upgraded, it needs to be processed accordingly; if the equipment cannot continue to be used or the repair cost is too high, it needs to be scrapped.

5. Execution of equipment scrapping: Dispose of scrapped equipment in accordance with relevant regulations and procedures. For example, recycling, dismantling, and destruction of equipment. At the same time, appropriate record and file management work needs to be done.
