Ce Chem Pharmaceuticals Interview Questions and Answers

HT, LT, and DG transformers are used for power distribution. Load changeover is done by switching between transformers.

• HT transformers are used for high voltage distribution, while LT transformers are used for low voltage distribution.

• DG transformers are used as backup power sources in case of power outages.

• Load changeover is done by switching between transformers based on the power demand.

• Proper safety measures must be taken while performing load changeover.

• Load changeover c...read more

There are two types of chillers: air-cooled and water-cooled. They work on the vapor compression cycle.

• Air-cooled chillers use air to cool the refrigerant, while water-cooled chillers use water.

• Both types of chillers work on the vapor compression cycle, which involves compressing and expanding refrigerant to remove heat from a space.

• Examples of chillers include centrifugal, screw, and absorption chillers.

• Centrifugal chillers are commonly used in large commercial buildings, wh...read more

PAC stands for Precision Air Conditioning, HVAC stands for Heating, Ventilation, and Air Conditioning, and AHU stands for Air Handling Unit.

• PAC is used in server rooms to maintain a constant temperature and humidity level to protect sensitive equipment.

• HVAC is used to control the temperature, humidity, and air quality in buildings.

• AHU is a device used to circulate and regulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.

• PAC temperature is typical...read more

Fire pumps are used to supply water to fire sprinkler systems and other fire protection equipment.

• Fire pumps can be electric, diesel, or steam-powered.

• They work by increasing water pressure and flow rate to the sprinkler system.

• Fire pumps are typically connected to a water source such as a tank or municipal water supply.

• Firefighting equipment includes fire extinguishers, hoses, and hydrants.

• Fire extinguishers are classified by the type of fire they can extinguish, such as Cla...read more

HVAC parameters refer to the various factors that affect the performance and efficiency of heating, ventilation, and air conditioning systems.

• HVAC parameters include temperature, humidity, air flow rate, pressure, and energy consumption

• These parameters can be measured and controlled using sensors, thermostats, and other devices

• Optimizing HVAC parameters can improve indoor air quality, reduce energy costs, and extend the lifespan of equipment

• Examples of HVAC parameters in acti...read more
