This number contains vital information about the car, such as its manufacturer, year of production, the plant it was produced in, type of engine, model and more.The VIN number has a specific format that is globally recognized.
This online service allows a user to check the validity of the car and get detailed information on almost any VIN number, search. VDS is used to specify a type of vehicle and may include information about the model, platform, engine and transmission. The first three symbols identify the manufacturer of the car. All trademarks, trade names, service marks, product names and logos appearing on the site are the property of their respective owners. If MOP is specified, the breaker or fuse protecting the equipment should match this number. Air Conditioning Heat Pump Data Tags Data-Tag Decoders: BTUs, Tons, Equipment Age. We have no relationship with advertisers, products, or services discussed at this website. Reading Mitsubishi S Series Answers MostThis article series answers most questions about air conditioning systems. Reading Mitsubishi S Serial Number Gives ACAir conditioner and heat pump manufacturers information; serial number gives AC age. We include examples of how to make use of the data to estimate equipment age, capacity, and even its condition. Not all of the terms we define below will appear on all equipment or motor tags.). Sketch at left on guessing the size of an air conditioner system is compliments of Carson Dunlop Associates. Reading Mitsubishi S Serial Numbers And DataAs we cite at REFERENCES, Carson Dunlop also provide a Technical Reference Guide with extensive details that aid in decoding HVAC equipment serial numbers and data tags. On older equipment the BTUH cooling capacity may be encoded in the model numbers. RATED COOLING CAPACITY discusses how to read the cooling capacity in BTUH or tons from air conditioning or heat pump tags. The serial number of modern HVAC equipment encodes the year and month of manufacture - thus the age of the equipment is shown. For equipment where the month and year of manufacture is not stated in plain English, Carson Dunlop Associates provides a Technical Reference Guide manual that decodes that data. In addition to specifying voltage, the cycles (50HZ or 60HZ) and current phases (typically one phase for residential equipment) may be specified. LRA on an air conditioning compressor describes the amperage drawn by the motor briefly during motor startup. Because it takes a lot of energy (torque) to get the still parts of an electric motor turning, LRA will always be higher than the current used to keep the motor turning once it has started (FLA or RLA). This is particularly true if the motor has an additional load (resistance to turning) at startup, such as trying to start an air conditioning compressor against refrigerant head pressure inside the compressor unit. The LRA of electric motors is 700 - 850 of rated current of the motor (or in some sources 5 to 7 times greater than RLA or FLA - a lot. ![]() In other words, the inrush current, because it is brief, does not need to figure in the selection of the wire sizing when wiring or fusing the motor, except to avoid nuisance tripping. Motors built to NEMA standards are assigned codes A through H. Each letter can be translated into multiplier x FLA to give LRA. To assist in avoiding nuisance tripping during compressor startup when high current is drawn momentarily, AC compressor circuit breakers may be permitted to be one size larger than the circuit breaker required by the wire size itself. Finally, an air conditioner motor will also draw its LRA current if the motor is frozen or stuck or has bad bearings - which we hope will quickly trip the circuit breaker or blow the circuit fuse. Thanks to Patrick Greaux for requesting clarification of LRA. Using the minimum permitted sized wire rather than the optimum-size to a compressor may save a few dollars.
