First, the use of household air conditioners

The National Energy Administration was quoted on January 4, 2012.

Article 12 The average use of various types of household appliances is:

Electronic Class: such as TV, audio, video recorder, charger, etc., service life is 10 years;

Motors: such as refrigerator, air conditioner, washing machine, electric fan, vacuum cleaner, etc., service life is 12 years;

Resistive electric heating: such as rice cooker, electric water heater, electric teapot, electric fried pot, etc., service life is 5 years;

Electrical light source: incandescent lamp, gas discharge lamp, dimming light, etc., service life is 2 years.

According to the regulations, the use of household air conditioners is clear for 12 years.

Second, the use of large central air conditioning equipment

Xiaobian review all the standard specifications, all did not make clear regulations. However, Xiaobian's implementation of the Regulations on the Implementation of the People's Republic of China Enterprise Income Tax Law of the People's Republic of China on the Minimian Republic of China issued the corresponding depreciation regulations, as follows:

Article 60 In addition to the financial and tax authorities of the State Council, the minimum period of depreciation of fixed assets is as follows:

(1) Houses, buildings for 20 years;

(2) aircraft, train, ship, machine, machinery and other production equipment, for 10 years;

(3) Equipment, tools, furniture, etc. related to production and operation activities, for 5 years;

(4) Tools outside the aircraft, train, and ships, for 4 years;

(5) Electronic equipment for 3 years.

Note: Large central air conditioning equipment refers to a central air conditioning apparatus in the form of "piston type, screw type, centrifugal" and lithium bromide.

According to the above provisions, "central air conditioning" can be independently defined as a depreciation period of fixed assets, but "depreciation year" is non- "use period".

So the problem is coming!

1. What questions and safety hazards have been used for domestic air conditioners?

1) Installation life

According to the "Room Air Regulator Installer", the installation unit should be responsible for the quality of the installation in three years, which is as follows:

. The installation life of the air conditioner should not be less than the product's life The air conditioner is installed within one year, and should not be used due to the normal operation and performance of the air conditioner; within three years after installation, there should be no major safety accidents in the installation of the air conditioner. After the air conditioner is installed, the user should check and perform the necessary maintenance according to the usage and report to the relevant department to ensure that the air conditioner is normal, safe and reliably.

2) Safety hidden dangers - users living in two floors have taken note!

It is understood that the national mandatory standard GB17790-1999 "Room Air Regulator Installation Specification" provides and requires the load-bearing, anti-pine, anti-rust and installation of air conditioning brackets, but the problem of the use of air conditioning brackets has not been clearly stated. The safety usage period of the air-conditioning outdoor machine holder is generally 6 years, and the specific situation is also affected by the factors of the bracket installation, environment, material, etc. After the consumer's air-conditioning outdoor unit, after using a certain period of time, it should be visually inspected or requiring air-conditioning manufacturers to designate maintenance units to host maintenance, and exclude air conditioning external machine bracket safety hazards to avoid safety incidents.

2. Large central air conditioning operation year problem

In a general bidding activity, central air-conditioning manufacturers will promise the bidding unit to the whole machine and compressor warranty time. Now the services provided by the manufacturers are different, indicating the confidence of their own product quality. We will first promise time from the compressor, the current is about 80,000 hours, then a single day 24-hour operation is calculated, about 9.1 years, if it is calculated as 18 years in 12 hours. If the property unit is carefully maintained for central air-conditioning equipment, there are still many examples of central air-conditioning equipment in 20 years. of course, the central air-conditioning component equipment is also corroded and dirty, which affects the cooling effect, and therefore, general central air-conditioning equipment can relatively ensure that their benign operation is about 12-15 years.

3. Is there any regulations for the use of air conditioning compressors?

At present, there is no clear provisions on the use of air conditioning compressors at home and abroad I think more is to encourage industry innovation to get more benefits But we check that a record is:.. According to some "ful

 Industrial air conditioning, chemical fiber industrial air conditioning, chemical fiber industry refrigeration, textile industrial air conditioning, dust-free workshop cooling, ventilation pipeline, cooling tower, freezer and other air conditioning units and accessories.
