Central air conditioning is an air conditioning system that is centrally controlled, centrally heated, noiseless, energy efficient and environmentally friendly. It delivers hot and cold water or air to each air-conditioning terminal through pipes and air-conditioning units to realize air conditioning, heating/cooling in the whole building or area.
The central air conditioning system includes water supply system (main control box, water pump, water tank, water treatment equipment, etc.), refrigerant piping system (main control box, compressor, condenser, refrigerant piping, etc.), duct system (air supply fan, duct, etc.), and user control system (thermostat, air flow controller, etc.).
So, central air conditioning what code? First of all, the central air conditioning repair and maintenance in most cases require electronic related certificates, such as electrical equipment maintenance, electrical equipment installation and other related certificates. Secondly, the central air conditioning also needs to choose the appropriate maintenance technicians according to different brands and models, because each brand of central air conditioning has specific technical requirements and maintenance methods. Finally, we need to note that the cost of central air conditioning repair is usually much higher than the cost of ordinary split air conditioning repair, because the central air conditioning spare parts and repair materials are branded original parts, which are very expensive.
In summary, the repair and maintenance of central air conditioning is more demanding, and you need to find professional technicians to carry out testing and maintenance. We also need to pay attention to follow the use of norms when we usually use the central air conditioning, so as to reduce the number of repair and maintenance, so that the air conditioning system is more healthy and stable operation.
