For big buildings like hospitals, hotels, airports, industrial buildings, and residential apartments the centralised air conditioning system is used.
AC (alternating current) is commonly used in various machines and appliances, including household items like refrigerators, air conditioners, and washing machines. It powers industrial machinery as well, such as motors and conveyor systems, due to its efficiency in transmitting power over long distances. Additionally, AC is used in lighting systems, including fluorescent and LED fixtures. Overall, any device that requires consistent power supply typically employs AC for its operation.
Did you mean EVAP? The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system.
Bevel gears can be used to change the direction of drive in a gear system by 90 degrees
Normally an AC unit does not have a vacuum pump in it. It does have a compressor - but the vac pump is a tool for installation. Once you have an air tight network of pipes connecting the indoor and the outdoor units you want to get all the moisture and air out of the system. (The under lieing principles apply to automotive AC as well) The method is to use the vacuum pump to suck the contents out - then refill with inert nitrogen, and rinse and repeat several times to effectively flush any particles of moisture or air out of the system. The tool which allows you to do this is a manifold gauge, it's critical when installing AC systems to remove all air and moisture from the pipes and not allowing any to get back in when you disconnect the schreader valve, so you have to disconnect after the refrigerant has been released into the pipework. If the refrigerant is R410a then when standing it could be at 10 bar pressure, so the best practice is to connect on the low pressure side of the system then run the system and disconnect with it running - so the pressure on the schreader is only about 7 bar. Installing split air conditioning systems should only be done by a trained and competent person though. In the UK there are specific rules about which qualifications are required to do this.
A lean burn system is a fuel burning system that uses an excess of air in an internal combustion engine. They provide a high air to fuel ratio and are used in some vehicles.
Distinguish between the centralised and the decentralised traditional political system in Nigeria?
centralised filing means that a single department is responsible for the filing of all organisation documents
should the information system function in a business be centralised or decentralised
A centralised filing system has all of the organisations information together in one large filing system. A decentralised filing system is when each department or section of the organisation stores its own records. (
Usually capacitors in an AC system are there to improve the power factor. Transformers are used to increase or decrease line voltages.
Throughout the world the system used for home electrification is alternating current (AC).

No, Judaism is not a centralised religion.
An AC compressor is part of an air conditioner which may be used in a car's AC system. The compressor is used to change the pressure between the AC's compartments in order to help condense the refrigerant gas back into a liquid.

In centralised tasks are done by one system and in distributed tasks are shared by the many computers
To detect an AC leak using AC leak dye, the dye is added to the AC system. The system is then run to circulate the dye. A UV light is used to inspect the system for any leaks, as the dye will glow under the UV light, making it easier to identify the source of the leak.
