A.Testing Parameter
| Temperature range | -20ºC~+150 ºC(Air-cooled type) |
| Humidity range | 20%-98% RH (the distribution range is as follows) |
| The cooling rate (no-load) | About 1ºC/min |
| The heating rate (no load) | About 3ºC/min |
| Temperature stability | ±0.5ºC |
| Analytical accuracy of temperature | 0.01ºC |
| Precision of humidity control | ±2%R.H |
| Temperature uniformity | ±2.0ºC |
| Humidity uniformity | ≤±3%R.H(+2,-3%RH) |
| Working noise | A sound level is less than 75 dB (A) (measured in a soundproof room with 25 C ambient temperature and less echo; measured the average value of 8 points by A weighting; measured the level of each test point is 1 metre from the noise source and the height is 1 metre from the ground). |
B.Machine Structure
| Material of inner and outer boxes | SUS # 304 |
| Outer box light source | High brightness lamp |
| Structural design of stratosphere | Effective avoidance of condensation at the top of the box |
| Observation Window | Observation sample use (W*L 28*35 cm) |
| Anti-sweat design of windows | Electrical heating device to prevent condensation of water and gas (40 W) |
| Test Holes | Can be used for connect external test power cord and signal (diameter 50 mm) |
| Machine pulley | Pulleys are movable and positioned with strong bolts (200Kg/wheel) |
| Insulation Layer | Rigid polyurethane foam (its advantages are: 1. High efficiency and energy saving, seamless after filling, strong bonding after curing. 2. Seismic and compressive resistance, no cracking, no decay, no falling off after solidification. 3. It has ultra-low temperature heat conductivity, weather resistance and heat preservation. 4. High efficiency insulation, sound insulation, waterproof and moisture-proof after curing. 5. waterproof performance is good, because the foam hole is closed, the sealing rate is 95%, and the rainwater will not permeate through the hole. |
| Inner rack | Movable adjustable grids and two stainless steel strip grids (5.0 cm per grille) |
| Box door | Double-channel heat insulation and tight gas to effectively isolate external temperature leakage |
C.Safety Protection System
| Leakage/Surge Protection | FUSE. RC electronic surge protection for leakage circuit breakers |
| Internal self-automatic detection and protection device of controller | 1. Data transmission detection between microcomputers 2. Temperature/Humidity Sensor→ circuit break or short circuit (+/- OVER) 3. Layer 1 high/low temperature over-temperature protection → Settings for operation control high and low temperature over-temperature protection |
| Fault Detection and Control Interface(Automatic Detection and Protection Device for External Faults) | 1. High Temperature Overtemperature Protection of the Second Layer→Electronic high temperature overtemperature protection device 2. Layer 3 High Temperature Overtemperature Protection→High temperature overtemperature protection device 3. Protection of water-cut incineration→Humidity water cut-off protection and electric heat water cut-off air incineration protection 4. Compressor protection→Refrigerant pressure protection and overload protection. 5. Extended Protective Device→Reserve two sets of fault detection input expansion protection devices for use. |
| Fault Abnormal Protection | Cut off control power supply and fault reason indication and alarm output signal when abnormal fault occurs. |
| Active Water Shortage Indicator | Initiative prompt for lack of water on machine. |
| Dynamic High and Low Temperature Protection | Dynamic adjustment of high and low temperature protection value with setting conditions. |
| Normal Temperature Protection | After shutdown, the test area of the machine will be protected automatically by lowering to the normal temperature. |
D.Refrigeration system
| Control Mode | 1. The control system automatically adjusts the operation of the refrigerator according to the test conditions, so that the equipment is in the best energy-saving condition. 2. The refrigeration capacity of the evaporator is switched by the solenoid valve driven by the control system. 3. Compressor return air cooling circuit. |
| Working Methods | The first-order compression is adopted for the 0 ~40ºC model. Binary cascade refrigeration is adopted at 40 ~70ºC. |
| Refrigeration Compressor | The original imported French Taikang fully enclosed low noise rotor compressor. |
| Refrigerant | R404a/R23 (ozone depletion index is 0, R23 is used in cascade refrigeration system). |
| Condenser | Air-cooled: Finned tube heat exchanger. Water-cooled: shell-and-tube heat exchanger. |
| Evaporator | Finned tube heat exchanger (also used as dehumidifier). |
| Plate heat exchanger | Stainless steel brazed plate heat exchanger (cascade refrigeration system used). |
| Throttling Device | Expansion valve + capillary. |
