Not all temperatures sensors are created equal and not all instruments and controllers use the same type of temperature sensors. So the first step in troubleshooting or replacing this type of sensor is to first recognize the type of temperature sensor being used.
The suction line of a refrigeration system is normally insulated with a flexible, closed-cell elastomeric material. Insulating the suction line is done to prevent condensate from developing and dripping off. It also limits the amount of heat added to the refrigerant as it travels back to the compressor.
A popular electrical component used on many control circuits is the step-down transformer. It is the power source for a separate lower-voltage circuit which typically controls the operation of a system.
They serve two purposes: They regulate water flow to maintain the system’s high-side pressure and stop the flow of water when the system cycles off so as not to waste water.
Determining that a compressor has failed on a refrigeration system is normally a relatively simple procedure. But, discovering why the original compressor failed may not be as simple.
There are many aspects of a technician’s job where a smartphone or tablet can be extremely useful. These devices allow a technician to search the Internet for technical information while on the job.
Gone are the days of the three basic refrigerants: R-12, R-22, and R-502. Today’s technicians need to be well-educated on all of the refrigerants they encounter.
When it comes to choosing a multimeter for servicing refrigeration systems, there are a lot of choices on the market. Careful planning should go into selecting the right meter.
