This amounts to a refrigerant charge of 9.7g/kW, roughly equivalent to the amount of propane in five cigarette lighters. Because it uses less propane, which is flammable, the new circuit is safer.

The refrigerant charge can be checked very accurately without gauges using a quality thermometer and manufacturer's charging chart. The capacity in Btuh can be calculated, determining if the unit is ...

This paper deals with an fault detection and diagnosis (FDD) of appropriate refrigerant charge amount (RCA) using a feed-forward backpropagation neural network (FBNN) for multi-split variable ...
