Cascade refrigeration system includes a high-temperature refrigeration cycle and a low temperature refrigeration cycle, which is connected to the evaporator vessel condenser, evaporator and condenser is also the role of energy transfer, the studio through a two-stage refrigeration system heat transfer out to achieve long warm purposes. 2, the refrigeration system design applications energy regulation technology, an effective treatment can guarantee but also on energy and cooling capacity of the refrigeration system for effective regulation in the case of the normal operation of the refrigeration unit, the refrigeration system operating costs and failure rates down to more economical status; 3, refrigeration works: the level of the refrigeration cycle are used against the card if the loop, which consists of two isothermal and two adiabatic components. 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; 4, the refrigerant: DUPONT company uses R404A (temperature cycle), R23 (temperature cycling); 5, accessories: expansion valve (US SPORLAN), the solenoid valve (Italy CASTEL), filter (US SPORLAN), the pressure controller (BAR RANCO), an oil separator (Europe and ALCO) and other refrigeration parts are imported; 6, with automatic and manual defrost circuit; 7, U-TYPE chip high-speed heating electric eel tube; 8, in a helical K-TYPE refrigerant brass; 9, imported high-efficiency power compressor (using the German "Copeland" water-cooled compressor); 10, using air-cooled condensers; 11, slope FIN-TUBE type evaporator; 12, high stability of the refrigerant R404, R23 environmentally friendly refrigerant; 13, refrigeration system using binary refrigerating (cascade) fast, stable; 14, imported solenoid valve, filter drier, capillary and other frozen components; 15, hot zone and the test area are using PID + SSR microcomputer temperature control, automatic calculation to control precision; 16, heat storage area, storage area using the multi-wing circulating fan, forced convection air flow, improve temperature uniformity effect; Thermal shock chamber air conditioning system: 1, forced ventilated balanced temperature method (BTC), which refers to the cooling system in the case of continuous operation, the control system according to the temperature set point of the automatic operation by PID output Results to control the heater output, and ultimately achieve a dynamic equilibrium; 2, built air-conditioned rooms, circulation air duct and the long axis of the centrifugal fan, refrigerator and the use of efficient energy regulation system, effective through efficient fan exchange, to achieve the purpose of temperature change. By improving the flow of air, improve air flow and the heater and air cooler heat exchange capacity, thereby significantly improving the chamber temperature uniformity; 3, heating: high quality nickel-chromium alloy electric heater, heating Good fast stability; Thermal shock chamber housing material: 1, shells are made of high quality A3 steel plate CNC machining shape, shell surface spray, more clean and beautiful; 2, Box liner made of high quality stainless steel light board (SUS304 ); 3, the entire cabinet is divided into upper, middle and lower three zones were the high temperature zone, test, low temperature zone, the impact test valve opens automatically when the high temperature region and low temperature region so as to achieve a high temperature and low temperature impact test; 4, insulation material: high-temperature fire insulation layer and high-density fiber cotton insulation, and use the new design of the K-type anti-sweat duct system; 5, the cable hole: the test area to open a cable hole Φ50mm; 6, the system meets the cold Reliability Test Specification heat cycle; 7, bottom of the machine can be fixed with high quality PU wheels, easy to move equipment; 8, the test sample is placed on the sample stage, high-precision pneumatic valve system drive or storage area of ??regenerative zone guide air circulation, to achieve cold test temperature uniformity; thermal shock chamber Standard: This product complies with GJB150.3-86, GJB150.4-86, GJB150.5-86 high and low temperature impact test, GB / T2423.1 , 2-2001GB10592-89 other national standards and meet the appropriate military standard; meet the CNS, MIL, IEC, also according to customer requirements manufacture non-standard products.
