【 Weak current College 】 air-conditioning system maintenance

(A) species

Air conditioning cold source press works can be divided into compression refrigerating and absorption chillers, cooling equipment layout scenarios can be divided into the central air conditioning and independent air conditioning and so on.

(Ii) management of main content

(1) is equipped with sufficient to meet the requirements of professional and technical personnel in charge of air conditioning systems management, and the periodic training.

(2) establishment of air conditioning system technical archives.

(3) according to the air conditioning equipment manufacturers and installation unit provides technical information and specification, developed air conditioning system operation and maintenance system, the development of large, medium and small repair plan and test plan adjustment.

(4) and pungent air conditioning repair, test tools, prepare appropriate quantity of spare parts, lubricants and refrigerants, establish professional maintenance services company for air conditioning and a parts supplier file.

(5) in accordance with the laws of nature and flow properties, etc., to determine in each of the air-conditioned start stop date and daily start stop time, as well as air conditioning in all the time.

(6) air conditioning electricity water metering and the air conditioning running cost accounting, calculation of air conditioning fee.

(7) in the air-conditioning equipment in new and adapted to focus on electricity load problems and noise pollution.

(8) the owners and occupants to install local air conditioning technical guidance, while the main contents are:

1) electricity load calculation and matching power supply line;

2) installation location and install mode selected, the main considerations of air conditioning efficiency, the appearance of a beautiful building and unity, and air conditioning installation safety and noise and drop impact on the environment.

(9) in the air conditioning system is down for a period of time (such as winter outage) to re-enter the runtime or air conditioner brings warmth and cold before you turn on the air conditioning system for the strict and detailed check adjustment of work, main contents are:

1) on the sealing part of the refrigerator to check, identify and adjustment;

The pipeline 2) cleaning dust;

3) check the various tests and indicates that the instrument is accurate and adjustment;

4) check all kinds of pumps, water towers, and other equipment is working properly;

5) check, clean and replace the gasket, filter materials, check the cooling water is qualified, check Add coolant and lubricant, etc.

(10) regularly tested for air conditioning systems in order to make the appropriate adjustments and improvements to keep the air conditioning system running at optimum levels.

(Iii) notes

(1) air conditioning system operating consumption of water, electricity and other energy in property management public water power and energy consumption in occupies a large percentage, energy-saving air conditioning management should run as an important work. Several energy saving measures are:

1) use the power saver change machine start and stop times, on different types of load differently, this is an important means of air conditioning energy saving;

2) guarantee and strengthen the related pipe insulation;

3) as far as possible, eliminating or reducing air conditioning room, various sources of interference;

4) to ensure the proper amount of refrigerant liquid;

5) condensed water removal, etc.

(2) air conditioning system operating noise is the property of the main sources of noise pollution, from the overall environment of the property, the air conditioning noise measurement, assessment, and reduce the work should not be ignored by the air conditioning management personnel.

(3) central air-conditioning system is to ensure that the building air quality of critical equipment, care should be taken to properly control fresh air ratio and note taking dust, sterilization and disinfection measures.
