What are the types of measuring tools in ref and air conditioning. HVAC Temperature Meter PCE-T 318. To understand where all of these parts are located think of the entire AC unit as two coils. PCE-T 318 is an HVAC temperature meter or digital contact thermometer used to measure temperature in laboratory industrial and heating ventilation air conditioning and refrigeration HVACR systems and applications.
When we talk about air conditioning a ton is the measurement of a units ability to cool. It holds both compound and high pressure. Some of the hand tools that service technicians use to work with include wrenches pliers hammers screwdrivers mallets vises taps twist drills dies chisels hacksaws and files.
Residential central air conditioners come in a range of sizes from 15 ton to 5 ton models. MERV Minimum efficiency reporting value for air filters NSOP Normal system operating pressure for airflow measurement corrections PD Preliminary Diagnostic a procedure as defined in this document PGE Pacific Gas and Electric Company PSC Permanent split capacitor motor type SCE Southern California Edison. On the hot side theres the compressor.
It checks for electrical current and notifies you if there is voltage present preventing you from being electrocuted. Mechanical hazards are posed by sharp edges moving machine parts and tools. Compressor A pump that pressurizes refrigerant.
Measuring tools can be very precise but low quality ones can lead to faulty measurements. Vacuum pumps are designed for quick evacuation of refrigeration systems and charging scales accurately weigh refrigerant tanks during charging and recovery operations. You can use a multimeter to detect electrical currents on wires switches or outlets.
Water vapor in the air tends to be low. When lifting and moving heavy equipment. On the cold side the evaporator and a fan blows air over the cold coils.
