FROST DETECTING SENSOR
FD SENSOR
1. Application
Any frost-free system found in domestic and commercial fridge-freezers,
vending machines, ice-makers, etc.
2. Features
Simple detecting principle
Highly sensitive
Ease of assembly
Replaces less-efficient conventional sensors
The FD Sensor has been developed to detect the level of accumulated frost
on the evaporator in frost-free systems, such as those found in domestic
fridge-freezers. It helps to eliminate unnecessary defrost cycles and also
increases the energy efficiency of the system.

Study (A)
A 12% of energy saving in a 420 liter domestic frost-free fridge-freezer was found by one of the major Japanese refrigerator manufacturers by the following test
procedures.
Test Procedure
The power consumption measurement was carried out in accordance with JIS C9607 power consumption test, item B (
ISO8561).
The test procedure was extended to one week to determine the full advantage of the defrost system using the FD Sensor.
Study (B)
Evaluation of the FD Sensor in a 130 liter domestic frost-free fridge-freezer was made by another Japanese refrigerator manufacturer.
They obtained an energy saving of over 10% using the same test method as in 5(A) above but including the opening and closing the fridge-freezers
doors.
Study (C)
FD Sensor
1) Environmental Temperature range :
40 C
80 C
2) Operating temperature range
:
40 C
5 C
3) Sensitivity
: 4 C 12 C
(Difference in temperature measured by both NTC Thermistors when no frost is recognized.)
Evaluation of the FD Sensor in a 400 liter domestic frost-free fridge-freezer made by a Japanese refrigerator manufacturer shows an energy saving of over 10%.
Measurement of this energy saving was made using the test method specified as in 5(A) above.
1) Nominal Zero power resistance
: R25 10k
3%
2) Rated B value
: B25 85 3435K
1%
3) Absolute difference between the two NTCs :
0.2% or
0.05 C at 25 C
