Product Overview
This test chamber is used for cold, heat, humidity and dryness testing of raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. The purpose is to confirm the products reliability of storage and transportation under high and low temperature alternating heat and humidity.
Technical Parameters
| Cooling system | |
| Operation mode | Air-cooled mechanical compression single-stage refrigeration mode |
| Heating and cooling devices | 1. Hitachi or Emerson low-temperature and low-noise scroll compressor (air-cooled heat dissipation method). 2. Cooling method: air cooling |
| Heat and cold exchange device | Single-stage refrigeration system, Emerson low-temperature and low-noise scroll compressor imported from the United States. Adopting ultra-high-efficiency SWEP cold coal heat and cold exchange design [made in Sweden (sus#316)], it is more efficient than the traditional internal spiral type. |
| Heating load adjustment | 1. The automatic adjustment of the cold coal flow rate device is adopted to effectively take away the heating load of the product to be tested, which is synchronized with German/Japanese technology. 2. Compared with traditional designs, the control stability and reproducibility are higher, and it achieves ultra-high performance in terms of power saving and energy saving. |
| Refrigeration compressor | Hitachi or Emerson low temperature and low noise scroll compressor |
| High efficiency components | 1. The condenser and evaporator adopt AC&R double spoiler type aluminum fin device. 2. The throttling devices adopt imported famous brand refrigeration accessories. |
| Expansion system | Capacity controlled refrigeration system |
| Evaporative condenser | All copper tube heat exchanger |
| Refrigerator control method | 1. The controller of the control system automatically adjusts the operating conditions of the refrigeration compressor according to the test conditions. The output cooling capacity can be controlled to achieve the principle of saving electricity and water. The working condition is more stable. Especially the operating humidity can save 30% of electricity. 2. Evaporation pressure regulating valve. 3. Compressor return air cooling circuit |
| Refrigerants | Honeywell R404a (ozone depletion index is 0) |
