HVACR PACKAGE DEAL FINAL PAPER 2026
SOLVED QUESTIONS AND FULL SOLUTION
UPDATED
◉ Air-source package heat pumps are commonly available in:
Answer: Side discharge, bottom, discharge, or wall mounted
configurations
◉ When a geothermal heat pump system uses antifreeze in the loop,
how is the antifreeze added to the loop?
Answer: By temporarily connecting the purge unit
◉ Why should the water flow be checked before checking other
systems operating characteristics
Answer: The flow rate affects the other system operating
characteristics
◉ How is the condensate from the evaporator dispose of in a
basement installation
Answer: Using a condensate pump
◉ In general, air-source heat pumps are sized to meet:
, Answer: The building cooling load.
◉ How can the water flow through a geothermal system be
determined?
Answer: By measuring the pressure drop across the co-axle coil and
comparing it to the manufacturers chart
◉ Which of the following is a critical operating parameter that
should always be checked on water source systems
Answer: water flow
◉ What is the purpose of using an outdoor ambient thermostat on a
heat pump installation?
Answer: To prevent the auxiliary heat from operating above the
system balance point
◉ Types of closed water loops include
Answer: Horizontal loops, vertical loops, and slinky loops
◉ What type of heat pumps are commonly installed above the drop
ceiling in each zone in a commercial building?
Answer: Horizontal water source heat pumps
