Product Usage
The rapid temperature change test box is suitable for aerospace
products, information electronic instrumentation, materials,
electrical engineering, electronic products, and various electronic
vitality parts to test various performance indicators in the
environment of rapid changes in high temperature and low
temperature. The whole box adopts an integral structure. Box
structure
The inside of the box is made of 1.0mm imported SUs304B stainless
steel plate, and the outside is made of 1.0mm cold-rolled steel
plate sprayed with plastic, and the insulation material is made of
ultra-fine glass insulation cotton.
3The door is sealed with double-layer silicone rubber sealing
material.
The observation window is made of multi-layer conductive film
tempered hollow glass, the size is 350x500mm. In order to prevent
the glass from frosting at low temperatures, a built-in special
safety voltage heating wire surrounds the heating belt. The supply
voltage is 36V, and there is a lighting lamp to provide
illumination for observation
There is a 450mm test hole with a plug on the side of the box. The
plug material is silicone rubber with low foaming, high and low
temperature resistance, and heat preservation.
5 An air-conditioning cabinet is installed on the back side of the
cabinet studio, in which humidifier, evaporator, electric heater,
fan, fan volute and other equipment are installed.
The temperature sensor is placed at the air outlet.
3 The air supply mode in the test box is the upper air supply and
the lower return air refrigeration system
Rapid temperature change test chamber refrigeration system and
compressor: In order to ensure the cooling rate and minimum
temperature requirements of the test chamber, this test chamber
adopts a dual cascade air-cooled refrigeration system composed of a
set of Taikang fully enclosed compressors. The cascade
refrigeration system consists of a high-temperature refrigeration
cycle and a low-temperature refrigeration cycle. The connecting
container is an evaporative condenser. The evaporative condenser is
also used for energy transfer. The heat energy in the working room
is transferred out through the two-stage refrigeration system to
achieve high temperature. the goal of. The design of the
refrigeration system applies energy adjustment technology. An
effective treatment method can ensure that the energy consumption
and cooling capacity of the refrigeration system can be effectively
adjusted under the normal operation of the refrigeration unit, so
that the operation cost of the refrigeration system And the failure
rate drops to a more economical state.
Refrigerant: adopt DUPONT company R404 (high temperature cycle),
R23 (low temperature cycle)
Auxiliary parts: expansion valve (Danfoss, Denmark), solenoid valve
(CASTEL, Italy); filter (Aiko); oil separator (Taiwan crown
pressure) and other refrigeration accessories are imported.
How Refrigeration Works
The high and low refrigeration cycle of the rapid temperature
change test chamber adopts the reverse Karyo cycle, which consists
of two isothermal processes and two adiabatic processes. The
process is as follows: the refrigerant is adiabaticly compressed by
the compressor to a higher pressure, and the work is consumed to
increase the temperature of the exhaust gas. After that, the
refrigerant exchanges heat with the surrounding medium through the
condenser isothermally and transfers the heat to the surrounding
medium. After the refrigerant expands through the valve adiabaticly
to do work, the temperature of the refrigerant decreases. Finally,
the refrigerant absorbs heat isothermally from the higher
temperature object through the evaporator, so that the temperature
of the cooled object is reduced. This cycle is repeated to achieve
the purpose of cooling down.
