Unit 1 Quiz

What is the primary purpose of the refrigeration cycle?

• To increase the temperature of a space

• To generate electricity

• To remove heat from a space and release it elsewhere

• To produce cold air for the environment

What is the function of an Air Handling Unit (AHU) in a building?

• To remove heat from the building

• To supply fresh air to the building

• To generate electricity for the building

• To distribute water throughout the building

Which process of heat transfer involves the transfer of energy through gases or liquid by movement of matter from a warm place to a cold place?

• Conduction

• Convection

• Radiation

• Absorption

What is the Zeroth Law of thermodynamics about?

• The conservation of energy

• The transfer of heat through direct contact

• The increase in entropy of an isolated system

• The thermal equilibrium between systems

What is the purpose of a cooling tower in various industries?

• To filter out dust particles from the air

• To prevent overheating and ensure efficient operation

• To reduce the efficiency of operation

• To increase the temperature of equipment and processes

Which component of a cooling tower is responsible for dispersing water in the form of fine droplets to enhance the rate of evaporation?

• Mesh

• PVC Filling

• Float Valve

• Eliminator

What is the purpose of the expansion valve in a split air conditioning system?

• To reduce refrigerant pressure and regulate the amount of liquid refrigerant entering the evaporator coil

• To compress the refrigerant and raise its pressure and temperature

• To release heat from the refrigerant and turn it into a liquid

• To absorb heat from the outdoor air and cause the refrigerant to evaporate

Where is the outdoor unit typically mounted in a packaged air conditioning unit?

• On the roof

• Inside the building

• On the ground

• On the ceiling

What is a pros of a split air conditioning system compared to a window air conditioning unit?

• Limited cooling capacity

• Targeted cooling

• Quiet operation

• Cost-effective

What is the purpose of a condenser in a refrigeration cycle?

• To increase the temperature of the refrigerant

• To remove heat from the refrigerant and turn it into a liquid

• To absorb heat from the outdoor air and cause the refrigerant to evaporate

• To regulate the refrigerant flow based on the temperature of the evaporator coil
