Heat Pump System in Year Round Air Conditioning
What is a heat pump system in the context of a year round air conditioning system?
As applied to a year round air conditioning system, a _________ is a system in which refrigeration equipment is used to remove and discharge heat from a space in warm weather and heat the space in cold weather:
a. air to air furnace
b. heat pump
c. hydronic system
d. dual furnace
Final answer:
Answer:
As applied to a year round air conditioning system, a heat pump is a system in which refrigeration equipment is used to remove and discharge heat from a space in warm weather and heat the space in cold weather.
So, the correct answer is B.
A heat pump is a system in which refrigeration equipment operates to remove heat from a space during warm weather and then heats the space in cooler weather. Essentially, heat pumps are capable of heat transfer from a cooler environment to a warmer one. This is achieved by transferring energy from the colder outdoor air into the warm interior of a house. They function like an air conditioner in the summer, and a heating unit in the winter.
It should be noted that, although heat pumps and certain heat engines can be operated in reverse, they cannot truly be reversed. The working fluid within a heat pump, typically a non-CFC refrigerant, gains heat from the cold outdoor air in the outdoor coils, making it gaseous. This operation makes a heat pump the most suitable system for year-round air conditioning.
