Across
  1. 1. Thermostatic Expansion Valve
  2. 4. HVAC component that uses outside air, under suitable climate conditions, to reduce required mechanical cooling.
  3. 5. roof top unit
  4. 6. The larger refrigerant line typically carries a cool gas and is insulated.
  5. 7. A self-contained heating unit designed to deliver heated air to a home or building
  6. 10. the part of an air conditioner or heat pump that absorbs the heat from the air
  7. 12. electrical safety device (a component) that removes electrical current from an electrical circuit when the current in the electrical circuit is too high
  8. 13. all-in-one heating and air conditioning system
  9. 16. Energy Efficiency Ratio
  10. 18. the system that distributes the heat in hot water through radiators
  11. 19. The number of degrees a vapor is above its boiling point at a specific pressure.
  12. 22. pipe that removes water from the evaporator coils.
  13. 24. heating system that uses tubing to run a hot liquid beneath the floor
  14. 25. he outdoor portion of an air conditioner or heat pump that either releases or collects heat
  15. 26. A plate or gate placed in a duct to control air flow by increasing friction in the duct.
  16. 27. the difference between its saturation temperature and the actual liquid refrigerant temperature
  17. 28. Chemical used in a cooling mechanism which changes from gas to liquid and the back to gas
Down
  1. 1. a device that monitors the indoor temperature and automatically adjusts your heating or cooling system to maintain the desired level.
  2. 2. the part of an outdoor air conditioner or heat pump that compresses and pumps refrigerant to cool
  3. 3. Annual Fuel Utilization Efficiency
  4. 8. the indoor part of an air-conditioning or heat pump system.
  5. 9. The Seasonal Energy Efficiency Ratio
  6. 11. packaged terminal air conditioner.
  7. 14. The smaller uninsulated refrigerant line typically carries a warm liquid.
  8. 15. a safety device that shuts off the gas if the pilot light goes out or the electric igniter on a furnace fail.
  9. 17. The lines that carry the refrigerant between the evaporator and condenser coils
  10. 18. the unit of heat required to raise one pound of water by one degree Fahrenheit
  11. 20. process of turning on when the thermostat or controller detects air above set temperature, cooling air until set temperature is reached, then turning off.
  12. 21. A vent that runs from a heat appliance to the outside of the building to remove the byproducts of combustion
  13. 23. the part of the furnace that is responsible for keeping the breathing air and the combustion process separate.
