Q

Kilo-watts are calculated on a motor by voltage, current, power factor or what?

A

Horse Power

23
Q

1 ton of cooling equals how much electrical power?

A

24
Q

What is the rate at which a material transfers heat energy?

A

Thermal Conductivity

25
Q

What is the Second Law of Thermodynamics?

A

Heat naturally moves from a warmer body to a cooler one

26
Q

What is the percentage of heat loss eliminated by insulating a hot surface?

A

90%

27
Q

When testing for complete combustion, where is the best location to check for Carbon Monoxide?

39
Q

Electrical demand limiting is also referred to as what?

A

Peak Demand Limiting

40
Q

BAS start/stop optimization saves energy how?

Limiting operation time of HVAC-related systems by delaying start time and accelerating the shutdown conditions while still meeting occupancy environmental standards

41
Q

Demand Control Ventilation works by adjusting outside air based on what?

A

On the number of occupants and the ventilation demands that those occupants create

42
Q

Heat Exchangers are used for what purpose?

A

Used for exchanging hear from waste streams to process streams while isolating the process stream from contamination and maximizing the degree of heat transferred from the waster stream to the process stream

43
Q

Solar, geothermal, and wind are examples of what?

A

Alternate Energy Technologies and Renewable Energy Technologies

44
Q

What is the fundamental concept of Cogeneration?

A

Using nonrenewable resources, but maximizing the use of the power created through the generation of both electricity and mechanical power from a single fuel source

Which alternate energy source is most cost effective?

A

Wind Energy

46
Q

Commissioning equipment is important to ensure what?

A

It operates efficiently and as designed to operate

47
Q

The need of commissioning and is importance is due to what?

A

The ever-changing tenancy of a building, to ensure controls are operating properly, to reduce repair costs

48
Q

Stationary Engineers should assist with or observe all functional testing of equipment and also?

A

Attend all training sessions

49
Q

What is the first step when managing a project?

A

Planning and Creation: 1. Define goals, 2. determine tasks, 3. Assign resources, 4. Establish a schedule, 5. Review your plan
