Performance parameters of hot and cold temperature shock test chambers
1. The temperature range (LED test area) :( high temperature 150 and low temperature are: A: -45;b：-55℃；c:-65 any temperature range can be customized);
Second, the control system adopts a large true color touch screen controller in Chinese and English display control system. Elevation memory capacity, can be set to store 120 sets of programs, large cycle setting 9999 cycles, each period of time maximum setting 999 hrs 59mins. With RS-232 communication interface and connection software, it can design programs, collect test data and records, call program execution, and realize remote control on the computer screen. The functions of three different test conditions can be independently set for high temperature shock, low temperature shock, and hot and cold shock, and the function of impact or constant temperature can be selected when performing cold and hot shock test conditions. It can be pre-warmed and cooled in advance in the start-up time control on the controller, and the starting position can be selected to start the cycle or temperature shock from high or low temperature, and it also has the function of setting the number of cycles to expand the automatic defrost.
3. Studio size can be selected (cm): 50 liters = height 40 height 35 depth 40;80 liters = 50 high, 40 high, 40 deep;150 liters = 60 high, 50 high, 50 deep;250 liters = height 70 height 60 depth 60;1000 liters = 1000 high 1000 deep 1000;More about the non-standard size of LED products, the studio can be customized non-standard.
4. The heating time of the high-temperature heat storage zone: RT 200 takes about 35min (to meet the corresponding relevant standards).
5. Cooling time of low-temperature cold storage area: RT -75 takes about 90min (to meet the corresponding relevant standards).
6. Temperature fluctuation: 05；Temperature uniformity: 20 meet the relevant criteria).
7. Insulation material: rigid polyurethane foam (its advantages are: 1High energy saving, no gaps after filling, strong bond after curing. 2.Shockproof and compression-resistant, no cracking, no corrosion, no falling off after curing. 3.It has ultra-low temperature thermal conductivity, weather resistance and heat preservation. 4.High insulation, sound insulation, waterproof and moisture-proof after curing. 5.The waterproof performance is good, because the foam hole is closed, the sealing rate is up to 95%, and rainwater will not seep through the hole. ）
8. The impact conversion time is about l0 seconds, and the impact recovery and stabilization time is within 5min (if you need to inquire faster, explain the requirements).
9. The cold shock low-temperature refrigeration system adopts binary compound compressor refrigeration (air-cooled or water-cooled can be selected), the main configuration adopts French Taikang or German BITZER compressor units, and the refrigerant adopts the American environmentally friendly DuPont.
