問題 #20
What instrument is NOT used to measure temperature?
答案：D
解題說明：
Step 1: Purpose of Each Instrument
* Hot-wire anemometer# Measures air velocity, NOT temperature.
* Bimetallic thermometer# Measures temperature using metal expansion.
* Thermistor# Measures temperature using resistance change.
* Thermometer# Directly measures temperature.
* Optical pyrometer# Measures high temperatures using infrared radiation.
Since ahot-wire anemometer measures airspeed, not temperature, the correct answer isA. Hot-wire anemometer.
問題 #21
In a typical compressed air system, energy can be saved by which of the following actions?
答案：D
問題 #22
A cooling tower is delivering water to a chilled-water plant. The cooling tower outlet temperature has a 6°C approach temperature to the ambient air, wet-bulb temperature. The outside air conditions are 20°C dry bulb,
60% relative humidity. Using the psychrometric chart, at what temperature can the cooling tower deliver water to the chilled-water plant?
答案：C
問題 #23
An air conditioning unit cools make-up air from 25°C (dry bulb temperature) and 50% relative humidity down to 13°C. What type of heat has been removed from the air?
答案：C
問題 #24
What is the main reason for using instrumentation in energy audits?
答案：B
解題說明：
Instrumentation in energy audits serves multiple functions, but theprimary reasonis to determine energy flows.
* Measuring Energy Flows:
* Instrumentation helpsquantify energy usein different systems, such as electricity, HVAC, and industrial processes.
* It helps identifywhere energy is used, lost, or wasted.
* Supporting Energy Conservation Efforts:
* By measuring energy flows, auditors canidentify inefficienciesand recommend solutions.
* Other Options Analysis:
* Saving energy (A):A result of energy audits, not the main purpose.
* Validating utility bills (C):Important but secondary to understanding energy flows.
* Supporting the local economy (D):Not relevant.
Thus, the correct answer isB. Determine energy flows.
