Maybe you have never taken notice, but the refrigeration cycle is taking place all around you. If you are an HVAC technician or learning how to be one, this can be a great time to learn more about this cycle if you just start paying attention everywhere you go.
Start looking for the major refrigeration components in every aspect of your life. Go into your kitchen and observe the refrigerator. Notice the type of evaporator. Is it finned, forces air, or automatic defrost? Feel for the heat rejection from the condenser. Is it coming from underneath or around the back? This will indicate if it is using a forced air cooled condenser or a static cooled.
Next time you go to your local grocery store, observe the coolers in the medium temperature and frozen foods section. Look for case thermometers, drain lines, ice buildup, and pipe chases. Listen for any noises associated with the equipment. Try to locate where the mechanical room and all the compressors are. Are there any units which are self-contained?
Observing and listening wherever you are will give indications of the refrigeration and air conditioning system. This includes convenience store, offices, and department stores. Look for ductwork, piping, thermostats, coolers or any other equipment associated with the mechanical refrigeration and air conditioning systems in the building. The methods modern building owners use to conceal their mechanical systems and equipment will sometimes amaze the intelligent observer.
