The large-scale central air-conditioning is generally referred to as commercial, multi-line air-conditioning, usually installed in commercial premises such as malls, hotels, office buildings, writing buildings, schools, etc. The central air-conditioning systems in these settings are generally a perennial exercise, so that the central air-conditioning systems in these settings are particularly focused on central air-conditioning protection, since central air-conditioning is a consumer, as is the case with the cars we see on the road, which usually go to the shop on a regular basis, which can make it more efficient, reduce malfunctions, save energy, and, importantly, make the air from its wind vents more fresh. So how does such a central air-conditioning system normally work out in terms of protection
Let's start by looking at what the cac multi-line protection is usually about:
General maintenance, which requires cleaning and maintenance according to the following items:
(1) outdoor mainframe condensers are cleaned (before the start of the summer) once a year。
Leakage, tightening and adjustment of the main cooling tube and valve (before the start of the summer), once a year。
(2) host power supply, tethering and dust removal (before opening in the summer), once a year。
(3) indoor vents, filters to clean and disinfect. The wind vents, windways, soft connections were checked and the damaged areas were repaired。
(4) indoor aircraft condensers, which are connected to the disk and are cleaned and blocked。
(5) cleaning of indoor condensers drainage pipes and repair of temperature preservation damage。
(6) vibration or noise screening and maintenance of indoor wind machines。
General maintenance, performance checks:
(1) operational data determination, analysis, adjustment of major equipment (host, end-of-pipe) twice a year。
(2) the measurement of circuit points, compressors, generators, insulation parameters, twice a year。
(3) the compressor initiates the control cabinet inspection twice a year。
(4) three-phase voltage, current and exhaust temperature pressure checks of compressors, twice a year。
(5) temperature testing of evaporationers, condensers and imports, twice a year。
(6) work conversion of valves such as electro-inflation valves, four-pass valves and electromagnetic valves, twice a year。
(7) working status tests for compressors, gas separators, oil separators, twice a year。
(8) high pressure, low pressure switches, high pressure sensors, and correction. Electronic control system action procedures and component checks, twice a year。
The fees for these repairs and maintenance projects vary, and it is particularly important to find a viable protection company, given the specific need for it to determine the final offer based on a site survey of the installation of the central air conditioner, the fact that the larger central air conditioner system will generally have a service contract with the company, the regular provision of protection services for the central air conditioner, the coordination of the cleaning of the central air conditioner during the protection period and the failure。
