Compressor data tag

  • How do I read my AC compressor label?

    Look at the model number (Located on the data plate stamped on the actual side of the compressor) on the compressor and there should be a number divisible by 12.
    It should start at 18 and not be more than 60 for residential AC units. 18 to equal 1.5 tons and 60 to equal 5 tons of cooling..

  • How do you read a compressor serial number?

    The serial number stamped or printed on the compressor nameplate consists of eight or nine characters.
    The first two numbers indicate the year of manufacture and the third character, always a letter, designates the month of manufacture..

  • What are the details of compressor?

    A compressor is a device used to compress air or other gases to pressures higher than atmosphere pressure.
    It compresses the air taken from the atmosphere and increases its pressure..

  • What is a compressor tag?

    A compressor label informs you the type of compressor your vehicle is equipped with such as model, supplier part number, production number, refrigerant (1) and refrigerant oil (2)..

  • What is the compressor in AC?

    The compressor is on the inside part of the condenser unit, and it's responsible for compressing refrigerant vapor.
    The compressor is the heart of your HVAC system.
    It transfers heat from the refrigerant (the liquid that cools the air) to the condenser (the device that takes heat away from the air)..

  • What is the purpose of compressor?

    A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
    An air compressor is a specific type of gas compressor.
    Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe..

  • Each compressor has an identification data plate, containing compressor model and serial number, mounted on the compressor body.
    When inquiring about the compressor or unit, or ordering repair parts, provide the model and serial numbers from the data plate.
  • RLA is a mathematical calculation required to meet Underwriters Laboratories Inc. (UL) approval only.
    The compressor manufacturer must run a series of tests to determine the Maximum Continuous Amps before the overload trips.
    Once that has been determined, UL says divide the MCC by 1.56 to determine the RLA.
  • The serial number stamped or printed on the compressor nameplate consists of eight or nine characters.
    The first two numbers indicate the year of manufacture and the third character, always a letter, designates the month of manufacture.Apr 5, 2018
HVAC data tag decoding: This article explains and translates all of the data found on information tags and stickers used on air conditioning and heat pump 

How do I know if a compressor is a model number?

Every compressor manufacturer has its own nomenclature for its series of compressors.
The information contained in the model number will vary from manufacturer to manufacturer, so you will need to obtain the coding used for each of the different compressors you service.

,

How do you know if a compressor is a high-temperature compressor?

Many times, the application range of the compressor can be determined, which identifies if the compressor is designed for high-, medium-, or low-temperature application; The Btu capacity is normally included, but, sometimes, instead of the Btu capacity, the model number will state the compressor’s motor horsepower or its displacement; .

,

What is a commercial air conditioning / heat pump data tag?

Commercial air conditioning or A/C/Heat pump units such as:

  1. the rooftop unit from which these data tag photos were taken often provides additional and critical capacity and service data

The first or left hand tag shows the equipment's operating capacity in both BTUH and watts, and shows a maximum air temperature at the unit.
,

What is a good psi vs a tag design press?

High side pressure is 270 psi vs. tag Design Press. 300 psi.
The compr outlet temp is 167 F and condenser coil outlet is about 88 F.
Ambient temp is 85 F and 70% humidity (Houston, TX).
Return temp to compressor is about 60 F.
All this seems within acceptable performance.
