2, high and low temperature chamber cooling system 

 1) the use of a hundred years, "Tai" Hermetic compressor unit, each unit have been in Europe, "Tai" computer network and a security code to monitor one by one, search the Internet via computer 
 2) refrigeration compressor: To ensure the chamber of the cooling rate and the minimum temperature requirements up to the chamber using a single-stage refrigeration system 
 3) The cooling system design should be energy regulation technology, an effective approach can guarantee the normal operation of the refrigeration unit in the case but also the energy consumption of refrigeration systems and cooling capacity for effective regulation, the refrigeration system operating costs and the failure rate down to a more state of the economy. 
 4) The cooling auxiliary components: air-cooled condenser coil, fin-type multi-stage evaporator, refrigeration parts and control devices primarily are used imported parts, such as: United States, "Ai high" dry filter; Italy "Fidel properly." solenoid valve; 
 5) Refrigerant: 404A imported 
 6) Cooling: Air Cooled 
 3, high and low temperature test chamber and control system 

 1) This device uses South Korea "880" or Korean "300" temperature control device, control accuracy ± 0.1 ℃ (display range)

 / Profibus / Dericenet / Modibus / CC-link 


 2) with PID self-tuning function, fuzzy control, multi-alarm function, the parameter mask function, the user adjust the function, the slope / thermal insulation function 
 3) The sensor is a class A Pt100 platinum resistance sensor, high precision and accurate 
 4, high and low temperature chamber electrical control system 
 1) The electrical control part of the French "Schneider" AC contactor, thermal relay, reliable 
 2) solid state relay as "Schneider" brand 
 3) Other components are well-known brand "Chint" 
 4) the electrical circuit design, simple operation 
 5) the right box for the electrical control cabinet, inspection, maintenance and easy 
 5, high and low temperature test chamber attachments 

 1) the left box fitted with cable hole φ50mm test available for customers to do the power test 
 2) inside the sample holder with two events, adjustable height 
 6, high and low temperature chamber security system 

 1) over-temperature alarm 
 2) leakage protection 
 3) Phase-phase protection 
 4) over-current protection 
 5) fuse 
 6) high and low pressure compressor protection 
 7) Compressor overheat protection 
 8) Compressor over-current protection 
 9) full-line fuse and jacket-type terminals 
 10) water protection 
 11) Grounding Protection 
 Second, the high and low temperature test chamber acceptance and implementation of standards: 

 The equipment to meet: 
 1. GB2423.1-03 "electric and electronic products environmental testing procedures for" Test A: low-temperature test methods; 

 2. GB2423.2-03 "electric and electronic products environmental testing procedures for" Test B: high-temperature test methods;
