Hotel Engineering Systems: Water, Electrical, and More
Hotel Engineering Systems
1. Cold Water Supply System
From the aquifers, the pipes have specific pressure. Engineers know the pressure at each point, so when a hotel wants to connect to the public pipe, they can do so. Once connected, we add a counter that measures the water we receive. This water goes to a tank where it is kept. Then, water goes through a pump that sends it either to the base of the building (Constant Pressure System) or to the top (Gravity Fed System) to a tank from where the water

Steam Power Plant
- The major components of this power plant are: (i) boiler, (ii) steam turbine, (iii) condenser, (iv) water feed pump, (v) electrical generator, (vi) cooling tower, etc.
- In a steam power plant, thermal energy is converted to electric energy.
- Water is supplied to the boiler through a feed water pump (1) from the water tank.
- The water in the boiler (4) is heated by transferring heat from the combustion of fossil fuel in the furnace. The boiler consists of an economizer (6) and a superheater
Types and Functions of Mechanical Couplings and Clutches
Understanding Mechanical Couplings
Durable Couplings are essential machine components used during power transmission. Their primary functions involve connecting shafts, facilitating mounting, and simplifying maintenance.
Drive Couplings
These couplings provide a direct link between two shafts, typically transmitting rotational motion. They often involve plates or screws connecting the elements, allowing for power transfer but generally not accommodating misalignment unless specifically designed to

Fire Extinguishing Installations
BIE (Fire Hose Stations)
A pressurized water fire extinguishing system comprising:
- Connection to a public water supply or fire pumping equipment.
- Network of pipes for water distribution.
- Hose reel (BIE).
Sprinklers
Individual, automatic sprinkler heads connected to a separate cold water pipe, capable of withstanding a pressure of at least 150 meters of water column (mca), and composed of:
- Water intake from the general network, independent
CT Installation: Components, Classifications, and Features
CT installation is provided with one or more processors, reducing high and low voltage switchgear and working with precise complementary functions. The function of a CT is to distribute electricity to different voltages while simultaneously allowing the connection to lines and networks at any point. CTs are classified in five ways:
Classification by Food (Supply)
- In Point: There is only one supply line connected to the derivation of the main network.
- In Step: Has one input and one output line to another
