Options :

A : VRF systems are limited to single-zone applications.

B : VRF systems rely on fixed refrigerant flow rates for efficiency.

C : VRF systems require extensive ductwork for air distribution.

D : VRF systems use a single refrigerant circuit to serve multiple indoor units.

Answer: D

Question 3

What is the purpose of the TIA-942 standard?

Options :

A : To standardize software development processes

B : To specify data center infrastructure requirements

C : To define cabling standards

D : To regulate IT security protocols

Answer: B

Question 4

In HVAC system design, what is the significance of calculating the heat load, and how does it impact the selection and sizing of the system components?

Options :

A : It ensures that the system can adequately cool or heat the space.

B : It affects the maintenance schedule and costs.

C : It determines the power requirements for the HVAC system.

D : It influences the selection of refrigerants and coolants.

Answer: A

Question 5

What is the function of a compressor in an HVAC system?

Options :
