57. What are Cassette air conditioners?
Cassette units work the same way as wall-hung split system units, with the difference being that cassettes are installed into the ceiling instead of on the wall. The indoor unit itself sits flush to your ceiling and distributes conditioned air through two, three or four sides of the unit. The outdoor unit of a cassette air conditioner is mounted outside, in much the same way as it would be for a conventional wall mounted split system unit. Cassette units are fairly unobtrusive and come in a range of sizes and capacities, so you have a reasonable amount of freedom when choosing where to install one. Generally speaking, cassette units are more appropriate for larger areas though. Because they take up a fairly large amount of space on the ceiling — and because the ceiling is normally composed of beams and joists, you will need to consult an expert installer to figure out exactly where you can safely mount one. As a general rule, a location that allows for clear, balanced air flow is also suggested for cassette units. The guidelines for installing an outdoor unit for a cassette tvpe air conditioner are the same as those for any other split system air conditioner. Outdoor units should be mounted in stable places where they won't vibrate, where they have plenty of free space on either side to allow airflow, where they're easily accessible for maintenance, and where they aren't likely to be exposed to corrosive substances. Noise should also be considered. The performance of cassette units is generally comparable to that of other types of systems, although because they're most commonly installed in commercial or office areas, they tend to be more powerful than wall-mounted systems. They are particularly well suited to circumstances where wail-hung split systems or other system types might not be an option. Cassette units tend to be more expensive than other systems. It has the distinct advantage in that it can be installed at the center of a room.

119. What is the use of a Ground Wire?
*A ground wire is a wire that is literally connected to the earth and acts as a backup in case a neutral wire fails.* Without one, the risk of electrical shock becomes a viable possibility. Ground wires are usually *green* or *yellow* in order to differentiate between neutral wires and hot wires, and therefore it is easy to tell the difference between it and other wires. Each electrical circuit inside of a home has two types of wire: hot and neutral. *Black wires are known as 'hot' wires*, and they carry electrical currents. Hot wires *may also be red*. *White wires* carry electrical currents away from a device, and these wires *are known as neutral wires*. When a white wire is broken, stray current is no longer carried away from a device, and neutralization is not possible without the help of a ground wire. In most instances, the ground is connected to a circuit breaker. When a neutral wire is no longer functional, this other wire will trip the corresponding circuit breaker and any electrical current is immediately stopped. Appliances will operate normally without the help of ground wires. In fact, if one is broken or missing, most people will not be able to tell the difference. If a large amount of high voltage has come in contact with the appliance, however, a person using that appliance may get a hefty electrical shock. *Therefore, it is important that all appliances include a grounded wire. *

70. What is an Air Handling Unit? Also known as AHU, it is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to a *ductwork* ventilation system that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork. Small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; these simple terminal units are called blower coils or Fan Coil Units (aka Split- type). A larger air handler that conditions 100% outside air, and no recirculated air, is known as a makeup air unit (MAU). An air handler designed for outdoor use, typically on roofs, is known as a packaged unit (PU) or rooftop unit (RTU).
An air handling unit; air flow is from the right to left in this case. Some AHU components shown are 1 — Supply duct 2 — Fan Compartment 3 — Vibration isolator ('flex joint') 4 — Heating and/or cooling coil 5 — Filter compartment 6 — Mixed (recirculated + outside) air duct

440. What is CFL?
Compact Fluorescent Lamp. Compared to the Incandescent Bulb, it consumes less power and has a longer rated life. There are two types of CFLs: *integrated *and *non-integrated lamps*. 1. Integrated lamps combine the tube and ballast in a single unit. These lamps allow consumers to replace incandescent lamps easily with CFLs. Integrated CFLs work well in many standard incandescent light fixtures, reducing the cost of converting to fluorescent. 3-way lamp bulbs and dimmable models with standard bases are available. 2. Non-integrated CFLs have the ballast permanently installed in the luminaire, and only the lamp bulb is usually changed at its end of life. Since the ballasts are placed in the light fixture, they are larger and last longer compared to the integrated ones, and they don't need to be replaced when the bulb reaches its end-of-life. Non-integrated CFL housings can be both more expensive and sophisticated. They have two types of tubes: a bi-pin tube designed for conventional ballast, and a quad-pin tube designed for an electronic ballast or a conventional ballast with an external starter. A bi-pin tube contains an integrated starter, which obviates the need for external heating pins but causes incompatibility with electronic ballasts.

432. What is luminous flux?
It is often used as an objective measure of the useful power emitted by a light source, and is typically reported on the packaging for light bulbs, although it is not always prominent. Energy conscious consumers commonly compare the luminous flux of different light bulbs since it provides an estimate of the apparent amount of light the bulb will produce, and is useful when comparing the luminous efficacy of incandescent and compact fluorescent bulbs. The Sl unit of luminous flux is the lumen (tm). One lumen is defined as the luminous flux of light produced by a light source that emits one candela of luminous intensity over a solid angle of one steradian. In other systems of units, luminous flux may have units of power.
