Safety Battery Thermal Shock Test Chamber Temperature Stability

Working principle
A. Low temperature storage room: The temperature state in the box
is determined by the working state of the heater, evaporator and
fan in the air duct. After the refrigerant flowing out through the
expansion valve throttling enters the evaporator in the working
room, it absorbs the heat in the working room and gasifies to
reduce the temperature of the working room; the gasified working
medium is sucked by the compressor and compressed into high
temperature and high pressure gas and enters the condenser It is
condensed into liquid in the middle, and then goes through the
screening program, and finally is throttled through the expansion
valve, and then enters the evaporator in the working room again to
absorb heat and vaporize, and then is sucked and compressed by the
compressor. This reciprocating loop work, so that the studio
temperature drops to the set temperature requirements
B. High temperature storage room: The central controller detects
the real-time signal from the temperature sensing element, compares
it with the set temperature signal, and obtains the comparison
signal, and the output signal of the instrument PID logic circuit
controls the on or off time ratio of the solid state relay to
adjust the heating The output power of the device can be adjusted
to achieve the purpose of automatic temperature control.
C. Impact temperature test chamber: The instrument automatically
controls the high and low temperature air valve, switches between
the low temperature or high temperature storage chamber, and forms
a closed-circuit air circulation system with the high temperature
box or the low temperature box, and quickly reaches the target
temperature of the test.
