Conditioning, and Refrigeration
with Complete Solutions
Air conditioning - ANSWER - The process to control temperature, humidity,
cleanliness, and movement of air in conditioned space
Air-Conditioning Heating and Refrigeration Institute (AHRI) - ANSWER - A national
trade association representing manufacturers of over 90% of U.S.-produced central
air conditioning, gas appliances, and commercial refrigeration equipment.
American Society of Heating, Refrigeration, and Air Conditioning Engineers
(ASHRAE) - ANSWER - Its membership is composed of thousands of professional
engineers and technicians from all phases of the HVAC/R industry. ASHRAE also
creates equipment standards for the industry
Blower - ANSWER - A centrifugal fan.
Boiling point - ANSWER - Temperature at a given pressure at which a fluid changes
from a liquid to a gas.
Brazing - ANSWER - Soldering with a filler material whose melting temperature is
higher than 840°F
Central residential air conditioning - ANSWER - Air is treated at a central station and
then distributed to the conditioned spaces by a series of ducts.
Combustion - ANSWER - The rapid oxidation of fuel gases accompanied by the
production of heat
