408l high and low temperature alternating test chamber Main refrigeration accessories
1、 Refrigeration compressor: France "Taikang" hermetic compressor single stage refrigeration system. This type of compressor has large cooling capacity, low noise, low energy consumption and high efficiency. It can operate stably and reliably for a long time, The overall structure of the system is reasonable and the operation cost is economical.
2、 Refrigeration evaporator: fin evaporator has higher heat transfer efficiency than general evaporator 30％, It has the advantages of beauty, small size and fast cooling.
3、 Main refrigeration accessories: solenoid valve Imported products are used in Japan's egret palace and castor, Italy, manual cut-off Fujian (Castor, Italy), and filters (Danfoss and Poland, USA);
4. The refrigeration evaporator is a complete set of American equipment, Single side welding and cold expansion;
6、 Cooling mode: air cooling;
7、 Refrigerant: USA Honeywell. Genetrom. R404 (environmentally friendly lithium fluoride).
8、 Humidification mode: evaporation humidification on the surface of shallow water tray;
9. Water supply device: full automatic water supply system, water shortage with alarm device.
10、 Humidification water: distilled water or distilled water.
408l high and low temperature alternating test chamber The structure of the chamber body was as follows
1. The test chamber is of integral structure, The electric control system is easy to operate and maintain. The inner wall of the test chamber adopts It is made of SUS304 stainless steel plate, and the outer wall of the box is made of cold-rolled steel plate, After pickling and phosphating, the surface is treated by electrostatic spraying;
2. Gate of test chamber: flexible suspension movable door and silicone rubber sealing strip are adopted. The device has good sealing performance and convenient adjustment. In order to prevent condensation or frost on the edge of the door frame and the door during the low temperature test, the electric defrosting device is set on the door frame and the door edge. In order to facilitate the observation of the sample, The box door is provided with 265 × 375 electrically heated anti frost insulating glass
3. The insulation material is made of superfine glass fiber, which has good heat preservation effect and does not frost on the surface of the test box, No condensation.
4、 On the side of the box body 050 test hole.
5. Water supply tank: front mounted, It's more convenient to add water
6、 Studio Lighting: 7W energy saving lamp.
408l high and low temperature alternating test chamber Overview:
