Cfesa Refrigeration Practice Test Direct

To get the most out of your CFESA refrigeration practice test, follow these tips:

Superheat is measured at the: a) Condenser outlet b) Evaporator outlet c) Receiver inlet d) Compressor discharge

The maximum allowable refrigerant leak rate per year for commercial refrigeration under EPA Section 608 (with 50+ lb charge) is: a) 15% b) 20% c) 25% d) 35%

The CFESA refrigeration certification is a career milestone. By taking this , you have identified your weak spots. If you struggled with the three-phase motor question, review motor theory. If the R-290 safety questions were confusing, re-read the UL standards for flammable refrigerants. cfesa refrigeration practice test

You cannot use a combustible gas sniffer wrongly calibrated. Must be specific to R-290 or R-600a.

Even a small release violates the Clean Air Act. You must recover even the vapor in hoses.

This prevents oil logging in the bulb and ensures accurate sensing of the gas temperature. To get the most out of your CFESA

Heat that changes the physical state of a substance without changing its temperature is known as: A. Sensible heat B. Specific heat C. Superheat D. Latent heat

A) At the bottom of the suction line (6 o’clock position). B) On the side of the suction line (10 or 2 o’clock position). C) On the liquid line before the filter. D) Inside the compressor terminal box.

The relay is wired in parallel with the compressor. If the condenser fan relay coil is open, the fan won't run, but the compressor (via a separate contact) will. If the R-290 safety questions were confusing, re-read

A potential relay is commonly used with which type of compressor motor? a) PSC b) CSIR c) CSCR d) Shaded pole

Which refrigerant is a common interim choice for replacing R-502 in a system with a major evaporator leak?
