1)This occurs when latent heat is decreased in a space

2. Heat gain from lights is calculated by multiplying this by 3.41.
3. To calculate the sensible heat gain due to ventilation for a room designed to be 75°F and the outdoor temperature is 87°F, which of the following equations would you use?
4. The U-factor is a number that represents the amount of heat flow through a building assembly due to a temperature difference.
5. Ventilation loads can be calculated using CFM per person or room changes per hour (RCH)
6. If the dry bulb temperature decreases, then the specific volume will                  .
7. This level is controlled by humidifiers and de-humidifiers.
8. The energy given off by lights creates a heat gain for a space
9. A dark colored roof will have a higher TETD value than a light colored roof at any time during the day
10. Psychrometrics is the study of gas/vapor systems.
11. This occurs when less than ideal air leaks into a space that must be accounted for in heating and cooling loads.
12. Wet bulb temperature readings indicate what?
13. Which type of heat transfer occurs when thermal energy flows through a solid material?
14. A change in the wet bulb temperature results in a change in the humidity ratio and relative humidity of the air.
15. On a psychrometric chart, as the humidity ratio decreases, then the latent heat of the air increases.
16. This occurs when the dry bulb, wet bulb, and dew point temperatures are the same
17. in thermodynamics, thermal energy flows from cold to hot
18. According to ASHRAE Standard 55, the comfort zone produces thermal comfort for 80% of the
19. When a heat pump is in the cooling mode, the                               unit is the evaporator and the   unit is the condenser.
20. Which of the following measures the winter seasonal performance of heat pumps?
