Heat Pumps Flashcards
What type of heat pump uses the outside air as a heat source or a heat sink.
Air-source heat pump
For a heat pump the refrigerant coil located inside that warms or cools air in the conditioned space is called what?
Indoor coil
For a heat pump the refrigerant coil that transfers heat to and from ambient air is called ____.
outdoor coil
Type of air-source heat pump that transfers heat between outside air and air inside using forced air for distribution.
Air-to-air heat pump
Type of air-source heat pump that transfers heat between outside air and air inside using a hydronic distribution system.
Air-to-water heat pump
What heat pump uses the earth as a heat source or heat sink for producing the desired temperature?
Ground-source heat pump
*** aka a geothermal heat pump
What is the type of heat pump that circulates refrigerant through an outdoor coil placed in direct contact with the earth?
Direct-exchange (DX) heat pump
What is the type of heat pump that circulates water through a secondary circuit that is placed underground or underwater?
Water-source heat pump
What heat pump system pumps water from and discharges water into a well or lake?
open-loop ground-source heat pump
Type of heat exchanger where heat is transferred between refrigerant from the indoor coil and water form the ground or water loop.
Water coil
(T/F) The four methods for guaging heat pump efficienct are:
