Lighting
• There are 3 basic types of artificial lighting:• Light-emitting diodes (commonly known
as LEDs).• Incandescent lamps, and electric
discharge lamps. • The fluorescent and compact fluorescent
lamps (CFL) common in foodservice use are types of electric discharge lamps

57
Incandescent lighting…1
• Traditional light bulb is actually an incandescent lamp
• It is a filament, encased in a sealed glass bulb. Electricity flows into the filament through the base of the bulb, and the glass is usually coated to diffuse the light.
• Most light bulbs have a relatively short life (up to 2000 hours).

58
Incandescent lighting…2
• If they are used at a higher voltage thanoriginally intended, their lives are even shorter. (The suggested voltage is usually stamped right on top of the bulb.)
• They also have rather poor efficiency (only 15 to 20 lumens per watt), which means they give off heat.

Electric Discharge Lamp
• The electric discharge lamp is one that generates light by passing an electric arc through a space filled with a special mixture of gases. That’s why you’ll sometimes hear them called gaseous discharge lamps.
• Fluorescent /Mercury vaporHalide or halogen/ High- and low-pressure sodium

Electric Discharge Lamp Features
• Unlike the incandescent lamp, the electric discharge lamp cannot operate directly bythreading or screwing it into a fixture.
• An additional piece of equipment, called a ballast, is required.
• The ballast is a current-limiting device that acts as a starting mechanism.
26/11/2013

Management-11 Menu Engg: Facilities
Design
62
Electric Discharge Lamp Features and Types…1
• There are two types of ballasts: the magnetic ballast and the electronic ballast.
• Electronic ballasts cost 60 to 70 percent more than magnetic ones, but the additional expense buys you a ballast that is more energy efficient.
• Electronic ballasts can be fitted with dimmers magnetic ballasts do not have that feature.

63
Electric Discharge Lamp Features and Types…2
• Both magnetic and electronic ballasts may generate harmonics, a distortion of powerfrequency that can create electromagnetic interference on power circuit with sensitive electronic equipment, such as computerized cash registers or order-taking systems.
• Ballasts even have total harmonic distortion (THD) ratings—the lower the percentage

Electric Discharge Lamp Features and Types…3
• Fluorescent lamps are the most common form of electric discharge lamp used in thehospitality industry.
• Unlike an incandescent bulb’s 2000 hours of life and 15 to 20 lumens per watt, the fluorescent tube will last from 7000 to 20,000 hours, with an efficiency of 40 to 80 lumens per watt.

1. The index measures the “naturalness” of artificial light compared to actual sunlight. A higher CRI (from 75 to 100) means a better color rendering.
2. So a CRI of 75 to 100 is considered excellent, while 60 to 75 is good, and below 50 is poor. Incandescent and halogen lamps have the highest CRI ratings; clear mercury lights usually have the lowest CRI ratings.

Measuring light…4 Power Factor
• Lighting devices are referred to as high power factor (HPF) or low power factor (LPF).
• Finally, the power factor (PF) is a measurement of how efficiently a deviceuses power.
• A new generation of fluorescents, known as T-5’s , can be paired with reflectors for better use of fewer lumens per watt than the popular T-8 fluorescents.

Measuring light…5 Power Factor
• A lamp that converts all the power supplied to it into watts without wasting any in the process has a power factor of 1. light.
• Often lamps that require ballastshave a PF less than 1 (e.g., 0.60 or 0.90), because some of the electric currentis used to create a magnetic field within the ballast, not to produce light.

How do HVAC systems work..1
• The heating plant will use one of several heat sources: electricity, natural gas, liquefied petroleum gas (LPG), fuel oil, or steam.
• The most commonly used is electricity but due to its shortage in India alternate fuel like High Speed diesel is used.
• The best environmentally friendly option is CNG(Compressed Natural Gas).

The Working in HVAC Centralized Heating
• Cold air from outside is drawn inside by fans and passes thru dust filters.
• The Pre-heater takes cold air and begins the heating process.
• This Pre-heater contains an element and a motor. It also acts as a dehumidifier.
• The air is later blown by the fans which have their own motors.

How vapor compression works to refrigerate air…1
• The refrigerant (which is, at this point, about 75 percent liquid and 25 percent vapor) leaves the metering device and enters the evaporator.
• The liquid evaporates as it moves along.• By the time it leaves the evaporator, it
should be 100 percent vapor. (This is known as the saturation point of the refrigerant.)

How vapor compression works to refrigerate air….2
• The vapor is drawn into the compressor by thepumping action of pistons and valves.
• It is superheated by the time it leaves the compressor, or the “high side” (meaning high pressure) of the system.
• The hot vapor travels through more tubes to the condenser, where it begins to turn back into liquid.

• Another fan is used here to help the condensing process, cooling the hot gas to help it return to its liquid state.
• By the time the refrigerant reaches the end of the condensercoil, it should be 100 percent liquid again.
• From here, an expansion valve controls the flow of the liquid refrigerant.

• Its pressure drops as it is forced throughthe valve, which causes its temperature to drop.
• The cold, low-pressure liquid refrigerant then cycles back into the evaporator and the process begins again.
• For measurement purposes, one ton of refrigeration is equivalent to the energy required to melt one ton of ice.

• Btu as the amount of heat needed to raise the temperature of one pound of water 1 degree Fahrenheit.
• The melting of one pound of ice absorbs 144 Btus, so the melting of one ton of ice (2000 pounds) would take:144 (Btus) x 2000 (pounds per ton) / 24 (hours) = 12,000 Btus per hour
