The procedure is as follows: adiabatic compression of the refrigerant through the compressor to a higher pressure, the power consumption of the exhaust gas temperature, after the refrigerant through the condenser and ambient media isothermal heat exchange medium heat to four weeks. After the refrigerant flows through the valve adiabatic expansion work, when the refrigerant temperature decreases. Finally, the refrigerant passes through the evaporator isothermal heat from high temperature object, the object to be cooled so that the temperature is lowered. This cycle so as to achieve the purpose of cooling the cycle. Rapid temperature change chamber control system: Cowan independent research KW-900 system controller microcomputer text, and France Schneider, Japan's rich soil and other electrical components constitute the electrical control system. 1, high-resolution color touch-screen interface (resolution 800 * 480) 7-inch widescreen and 10-inch widescreen (option) 2, high-capacity memory 127 program group, each 530 hours 3 long run, the program cycle may 32000 , coupling cycles 32000 4 program, support 1G-8G U disk to download the backup history data, historical curve, support plug and pull 5, built large storage, you can store 90 days calendar data, historical curve (when the sampling time is 1min) 6 auto-temperature storage temperature compensation, automatic temperature compensation cryogenic storage 7, support the single temperature operation. 8, Touch Interactive parameter input mode 9, supports English, Chinese 10, provides built-in SMPS's I / O RELAY BOARD- simplified wiring and cost savings 11, while supporting dry T, K, PT100 and other sensors 12, 13 for convenience PC monitor for easy setting of output up to 24 14, built on the world's most advanced PID algorithm automatically tuning function 15, to provide a strong communication environment and supports multi-branch structure 254 16, superior functionality and ARW Fuzzy start - inhibition overtravel 17, program type high temperature → low temperature, low → high temperature, room temperature → hot → normal → low , normal → low → normal → high temperature 18, support 1G-8G U disk to download historical data, historical curve, can plug and pull 19, the backup history data, historical curve, including temperature PV SV TIME.
