# Quick Answer: How Do I Tell What Horse Power A Freezer Compressor Is?

## How do I find out the HP of my refrigerator compressor?

Re: compressor horsepower Most compressors have the BTU rating encoded in the compressor model number. If not it is stamped on them somewhere. A household refrigerator is usually not much larger than 1150 BTU, so you’ll be safe to pick one for up to 1/4 HP.

## What is HP in compressor?

HP is horsepower, or the amount of work that a motor can perform. HP is not as important as pressure and flow in determining if your compressor will work for you, as newer & more efficient compressors can do more with less HP!

## How do you calculate HP to LRA?

LRA (lock rotor amps) can be converted to HP using this formula: (LRA Watts x Volts)/ 746 Watts = Horsepower.

## How many HP is a fridge?

one horsepower is 746 watts so a 330 watt fridge would be 0.44 hp.

## How do I know if my refrigerator compressor is not working?

The best way to tell if something has gone wrong with the compressor is to pull the fridge slightly out from the wall and listen closely. If the motor is running with a slight humming sound but the temperature is above what its normal range should be, then it’s likely there could be a problem with the compressor.

## How do I know what horsepower my compressor is?

To to calculate the real hp, we need to multiply the kW by the motor efficiency and then convert to hp. As an example, a 100hp motor and 95% efficiency would need input kW of 78.5kW. The motor efficiency rating is line 7 in the CAGI data sheets. All of those compressors are “100 hp” compressors.

## What compressor is used in Panasonic AC?

Rotary Compressors (Variable Speed) Panasonic has the smallest size variable speed rotary compressor in the industry. Panasonic rotary compressor has a good reputation with clients all over the world, and are commonly used for room air conditioning and refrigeration.

## How much HP does an air compressor need?

Air compressors typically have a horsepower rating between 1.5 and 6.5, though some larger, stationary air compressors can have up to 15 HP. If you are using standard electric power outlets, you’ll need an air compressor at 2 HP or less because standard AC cords require lower voltage to function.

## What is the difference between RLA and LRA?

LRA – Locked Rotor Amps: The current you can expect under starting conditions when you apply full voltage. It occurs instantly during start up. RLA – Rated Load Amps: The maximum current a compressor should draw under any operating conditions.

## Is LRA the same as starting amps?

Locked rotor current is basically the current drawn by the motor at its rated voltage when its rotor is kept stationary or in other words rotor is not spinning or rotating. So when we start a motor, its rotor is already at rest. This means, starting current and locked rotor current should be same.
