A TXV ( Thermal Expansion Valve )is an
interactive device, in that it senses system ( evaporator )
pressure and temperature, and adjusts the flow of Freon so as to
maintain a given superheat. Without this, the coil would be
starved (not getting enough Freon to work at capacity) at some
times, and flooded (too much Freon, possibly damaging the
compressor) at others. |
