In summary, a step-up transformer can be installed to correct the efficiency issues caused by low supply voltage for a regrigeration compressor rated at 208/230V in a mobile unit. However, it should only be used if there is a certainty that the voltage will drop below 208V. Additionally, the length of the supply line and the power rating of the compressor should be taken into consideration when determining the need for a step-up transformer. It is also possible for the transformer to saturate if the increase in voltage is too big.

I have a regrigeration compressor that is rated 208/230V This application is in a mobile unit so supply voltage will vary depending upon what is available.. when the supply voltage drops below 208v ( due to long supply lines) the compressor heats up at times and becomes less efficient ( at times even stopping due to internal protection). I would like to install a step-up transformer to correct this situation.
My question is, when the supply voltage IS high enough (208-230) will this affect the transformer?

Yes. it would.
Step up transformer will not know what the input voltage is. It will step up whatever you feed it.
You should use the step up only if you are sure the voltage will drop below 208v.

I would use thicker gauge supply line. How long is it, and what is the power rating of compressor?

And yes that would. Suppose your transformer steps up from 200 to 220 , i.e. by 10% . At 220, it will step up to 242 , furthermore, it is possible for it to saturate if increase in voltage is too big.
 

1. What is the purpose of boosting voltage for the refrigeration compressor in a mobile unit?

The purpose of boosting voltage for the refrigeration compressor in a mobile unit is to ensure that the compressor receives enough power to operate efficiently. This is especially important in mobile units, as they may experience fluctuations in voltage due to movement or external factors.

2. How does boosting voltage affect the performance of the refrigeration compressor?

Boosting voltage can improve the performance of the refrigeration compressor by providing a stable and consistent power supply. This can result in faster cooling times, more efficient operation, and longer lifespan of the compressor.

3. What are the potential risks of boosting voltage for the refrigeration compressor?

Boosting voltage can potentially damage the compressor if the voltage is too high. This can lead to overheating, increased wear and tear, and ultimately, failure of the compressor. It is important to carefully monitor and regulate the boosted voltage to ensure it does not exceed safe levels.

4. How can I determine the appropriate voltage for boosting the refrigeration compressor?

The appropriate voltage for boosting the refrigeration compressor will depend on the specific model and requirements of the compressor. It is recommended to consult the manufacturer's guidelines or seek the advice of a professional to determine the appropriate voltage for your specific compressor.

5. Are there any alternative methods for boosting voltage for the refrigeration compressor?

Yes, there are alternative methods for boosting voltage for the refrigeration compressor, such as using a voltage regulator or a power conditioner. These devices can help regulate and stabilize the voltage without the need for manual adjustments. However, it is important to carefully research and select a reliable and compatible option for your specific compressor.
