Water cooled systems introduce an additional source of liquid, which can be a potential source of contamination and damage to the IT equipment. Additionally, water cooled systems require more maintenance than air cooled systems and are more expensive to install due to the additional cost of the cooling tower, piping, and pumps.

A voltage regulator controls the voltage produced at the output of the alternator. It's a device that maintains the output voltage of an alternating current (AC) power source within a safe range. The voltage regulator compares the actual output voltage to the desired voltage level and adjusts the voltage accordingly.

Voltage Meter, Voltage Stabilizer, and Voltage Backup Device are not devices that control the voltage produced at the output of the alternator. They are different types of equipment and have different functions.

A voltage meter is a device used to measure the voltage in an electrical circuit. A voltage stabilizer is an electronic device that maintains a constant voltage level. A voltage backup device is a device that provides temporary backup power in case of an electrical outage.

Watts measures the real power drawn by the load equipment and is determined by multiplying the volts and amps of the load

There are five common approaches to removing unwanted heat from an IT environment:

Air conditioning: using mechanical cooling to remove heat from the air.

Air economization: using outside air to cool the IT environment when the temperature is cooler than the desired temperature inside the data center.

Liquid cooling: using a liquid coolant to absorb and remove heat from IT equipment.

Evaporative cooling: using water evaporation to cool the air.

Immersion cooling: submerging IT equipment in a liquid coolant to remove heat.
