tools & instruments
THIS TOOL IS USED TO MEASURE VOLTAGE, CURRENT, AND RESISTANCE.
WHAT IS A MULTIMETER?
THE "HEART" OF THE REFRIGERATION SYSTEM
WHAT IS THE COMPRESSOR?
THE REFRIGERANT COMMONLY REPLACING R-22 IN NEW RESIDENTIAL SYSTEMS.
WHAT IS R-410A
THE FORMULA V=I x R IS KNOW AS THIS LAW
WHAT IS Ohm's LAW?
AIRFLOW IN HVAC IS MEASURED IN THIS UNIT.
WHAT IS CFM (CUBIC FEET PER MINUTE)?
THIS HVAC TOOL REMOVES AIR AND MOISTURE BEFORE CHARGING THE SYSTEM.
WHAT IS A VACUUM PUMP?
THIS DEVICE CONTROLS VOLTAGE FROM 120V/240V DOWN TO 24V
WHAT IS A TRANSFORMER?
THE EPA SECTION THAT REQUIRES CERTIFICATIONS TO HANDLE REFRIGERANTS.
WHAT IS EPA 608?
MOST HVAC CONTROL CIRCUITS OPERATE AT THIS VOLTAGE.
WHAT IS 24 VOLTS?
TOO MUCH OF THIS "RESISTANCE" IN A DUCT REDUCES SYSTEM EFFICENCY.
WHAT IS STATIC PRESURE?
THIS TOOL CONNECTS TO SERVICE VAVLES TO READ SYSTEM PRESURES.
WHAT IS A MANIFOLD GAUGE SET?
THIS COIL INSIDE THE AIR HANDLER ABSORBS HEAT FROM INDOOR AIR
WHAT IS THE EVAPORATOR COIL?
THIS TERM DESCRIBES REDUCING REFRIGERANT PRESURES INTO A TANK FOR REUSE
WHAT IS RECOVERY?
THIS TYPE OF CIRCUIT HAS ONLY ONE PATH FOR CURRENT TO FLOW
WHAT IS A SERIES CIRCUIT?
THIS COMPONET IMPROVES INDOOR AIR QUALITY BY TRAPPING PARTICCLES.
WHAT IS AN AIR FILTER?
THIS SAFTEY TOOL DETECTS REFRIGERANT LEAKS
WHAT IS ELECTRONIC LEAK DETECTOR?
THIS DEVICE STORES AND RELEASES ELECTRCITYTO HELP START MOTORS
WHAT IS A CAPACITOR?
NEW REFRIGERANTS ARE BEING DEVELOPED WITH LOWER VALUES OF THIS ENVIROMENTAL IMPACT RATING
WHAT IS GWP (GLOBAL WARMING POTENTIAL)?
THIS COMPONET ACTS LIKE A SWITCH CONTROLLED BY A COIL OF WIRE
WHAT IS A CONTACTOR OR RELAY?
THIS TYPE OF DUCT MATERIAL IS LIGHTWEIGHT, FLEXIBLE AND OFTEN INSULATED.
WHAT IS FLEX DUCT?
THIS GAS AND REGULATOR ARE USED TO PRESSURIZE A SYSTEM FOR LEAKS TESTING
WHAT IS NITROGEN?
THIS DEVICE PROTECTS THE SYSTEM BY OPENING WHEN SYSTEM GETS TOO HIGH OR TOO LOW
WHAT IS A PRESURE SWITCH?
THE DEFFERENCE BETWEEN RECYCLING AND RECLAMINGING REFRIGERENT.
RECYCLING CLEANS REFRIGERANT FOR REUSE ON SITE,
RECLAMING RESTORES IT TO AHRI PURITY STANDARDS
IN A 240V SYSTEM, L1 AND L2 PROVIDE POWER IF ONE LEG IS LOST WHAT USUALLY HAPPENS?
THE SYSTEM WILL NOT RUN OR WILL ONLY PARTIALLY OPERATE, CAUSING FAILURES,
NAME TWO FACTORS THAT POOR DUCT DESIGN CAN CAUSE IN SYSTEM
LOW AIR FLOW AND REDUCED EFFICIENCY
