Web this is how to use a superheat charging chart, to know how to find a target superheat and compare it to the actual. You will find the chart that summarizes all total superheats further on. The temperature of a liquid refrigerant when it is cooled below its condensing temperature. Web most manufacturers will have you charge a piston system in cooling mode using a chart or calculator where you first find the target superheat. 3 superheat calculation examples for r.
Web now all you have to do to determine the required superheat is to plug these three load conditions into a superheat chart. The chart would say that the machine should be operating at 13 o superheat under those load conditions. To use the chart, you will usually need: Remember that the target superheat will change as the building lowers in wb and while charging refrigerant. Web input these temperatures in a superheat chart, calculation, app, or digital manifold set in order to determine the target superheat at that moment.
Web now all you have to do to determine the required superheat is to plug these three load conditions into a superheat chart. Remember that the target superheat will change as the building lowers in wb and while charging refrigerant. Use the refrigerant drop down for access to over 100 refrigerants. Web when charging a fixed orifice a/c system, you can use the chart below to figure out the proper superheat to set once all other parameters have been accounted for. Sometimes these charts are available from the unit's wholesale distributor, manufacturer's web site or installation/service manuals.
