ASH2
Superheat Accessory Head Measures
Refrigerant Pressure and Temperature
BREA, Calif., December 16, 2003-- -- Fieldpiece Instruments announces the immediate availability of the ASH2 Superheat Accessory Head, which enables DMMs to measure both refrigerant pressure and temperature simultaneously. After measuring suction line temperature and pressure, it then calculates and displays the actual superheat. The ASH2 head works with all of Fieldpiece’s modular instruments. It slides on to the HS30 series stick meter. The ASH2 head can also be used with the data logger to record measurements over time. When used with the Fieldpiece Electronic Handle, EHDL1, it acts as a standalone tool. It also connects to most DMMs using Fieldpiece's AHDL1 adapter handle.
The ASH2 comes with a
thermocouple that plugs into the ASH2 and attaches to the suction line. The
user connects the pressure of the ASH2 input to the suction line via a hose.
The hose is not included.
“Now every technician can easily and quickly measure superheat. No more
winging it!” said Rey Harju of Fieldpiece Instruments. “The ASH2
measures both suction line pressure and temperature at once, for either R-22
or R410-A refrigerant. And it works with the instruments you already have."
ABOUT SUPERHEAT
Measuring Superheat is important because it can prevent damage
to the air conditioner and make it run more efficiently. Superheat is the
difference between the boiling point temperature of the refrigerant in the
evaporator coil and the actual temperature of the refrigerant (gas) as it
leaves the evaporator. After boiling, the refrigerant continues to warm up.
The number of degrees it “warmed up” after boiling is called the
superheat. Under worst case conditions (low load), the refrigerant in the
evaporator boils off near the end of the evaporator coil. To make sure liquid
doesn’t enter the compressor under the worst case condition (low load),
the AC manufacturers publish charts indicating what the superheat should be
at a given indoor wet bulb measurement and outdoor air temperature. If the
superheat is too high, the air conditioner will be inefficient. If superheat
is too low, you risk flooding the compressor. You can change the superheat
by adding or taking away refrigerant.
Measuring superheat is the best indication on a fixed orifice system of the
proper refrigerant charge and operating conditions. If everything else is
working properly and the actual superheat is too high, add refrigerant. If
it is too low, remove refrigerant. Using superheat to determine proper charge
enables an air conditioner to deliver the best reliability and the best efficiency.
