Application:
Thermal Shock Chamber is ideally designed for testing most
commercial products to see how they withstand drastic temperature
changes, a harsh condition that subject a product to the most
extreme temperature conditions, instantly.Some times with liquid
nitrogen cooling if request more strictly temperature. Thermal
shock test is used as a vital method to quality inspection for all
types of electronic products, electric appliance, and products from
communication, instrument, automobile, plastic, metal, food,
chemical, building materials, medical and aerospace industries.And
the purpose of testing a product under these circumstances by a
thermal shock chamber is to observe changes in the products
characteristics and check for failure occurrence of different
materials and thermal expansion coefficients. So be sure that these
thermal shock chambers are prohibited to flammable explosive easily
to volatile substances sample test or storage, corrosive substance
sample testing or storage, biological sample test or storage,
strong electromagnetic emission source sample test.
Three Zone Thermal Shock Chamber means the chamber consist of high
temperature zone, low temperature zone, and testing zone. The test
sample is in static mode. While Two Zone Thermal Shock Chamber
consist of high temperature zone, low temperature zone only. And
the test sample is moving up and down along with the built in
air-controlled hanging basket.
Thermal Shock Testing Method
This kind of test are required a condition that exposes test
items/products to alternating low and high temperatures to
accelerate failures caused by temperature cycles or thermal shocks
during normal use. And the transition between temperature extremes
occurs very rapidly, often greater than 15 °C/min.

Variable Frequency Control Technology of Refrigeration System
In the frequency conversion refrigeration system, even if the power
frequency 50HZ is fixed, can change the
frequency through the frequency changer, thus adjusts the
compression rotational speed, causes the cold quantity
continuously to change, guarantees the compressor movement load in
the test box the actual load to match (namely
test body temperature Increase, the compressor frequency to rise,
improve the cooling capacity, on the contrary, the
compressor frequency to reduce and reduce the cooling capacity)
greatly saves the unnecessary loss of operation to achieve
energy-saving purposes. In the beginning of the test chamber can
also run by increasing the frequency of the compressor to improve
the capacity of the cooling system to achieve the purpose of rapid
cooling.
The chamber adopts frequency conversion refrigeration system, which
can precisely control the temperature of the box body, make the
temperature of the box body constant, the temperature fluctuation
is small, and the suction and discharge pressure of the
refrigeration system is stable and the compressor runs stably and
reliably. Electronic expansion flow servo.
Refrigeration system technology Other energy - saving technologies
A) The use of PID + PWM principle VRF technology (electronic
expansion valve according to the thermal conditions of flow
control)
Low-temperature working state, the heater does not participate in
the work, through the PID + PWM regulation of the cooling (cooling
capacity of the air flow control system); low-temperature working
conditions, the use of the principle of PID PID VRF technology
(refrigerant flow control) Flow rate and flow direction of the
cooling pipe, cold side of the pipeline, heat the next three-way
flow pipe to adjust to achieve the work of the temperature is
automatically constant, this method in low temperature conditions,
the studio can automatically achieve a constant temperature, Low
temperature conditions, can achieve a 30% reduction in energy
consumption. The technology is based on Danfoss ETS system
electronic expansion valve, can be applied to different cooling
capacity requirements of the cooling adjustment, both at different
cooling rate requirements, to achieve the compressor cooling
capacity adjustment.
B) the size of two sets of compressor design technology, according
to load conditions automatically start and stop (large series is
designed)
The refrigeration unit is equipped with a set of semi-hermetic
compressors composed of binary cascade refrigeration system plus a
full-density single-stage refrigeration system. Configure the
mother; according to the load conditions inside the box and the
cooling rate of intelligence to open the different compressor
groups, so that the cooling capacity of the box and the compressor
output power to achieve the best match, in order to achieve the
best operating conditions in the compressor section circle to
Extend the service life of the compressor. More importantly, a
large set of traditional design compared to the energy-saving
effect is very obvious, you can achieve more than 30% of the
temperature control. With VRF technology)
