Detailed Product Description: | Function: ? Environmental test chamber is mainly based on GB 21519-2008 and GB/T20289-2006 standard requirements of customized ? Environmental test chamber by the studio, conditioning equipment, auxiliary equipment, control system components. Conditioning systems, including the heater, evaporator and air supply devices, auxiliary equipment room cooling unit, the control system includes a temperature controller, program settings, security alarm devices. ? In order to fully meet the test air flow rate ≤ 0.25m / s and ambient temperature 20 ± 2 ° C standard requires Division I based on years of industry experience in manufacturing, the use of multiple ventilation pipe evenly distributed and the bottom of the porous air details of the process supporting a unique air circulation system devices, to avoid air flow circulation in the box there are dead ends, product temperature and humidity uniformity to ensure that the environmental requirements of the test. ? Control system uses PLC treatment, the LCD touch screen control, heating and cooling to automatically adjust with the equipment, the actual temperature and set temperature deviation, control, stepless adjustment, small temperature fluctuations. ? Equipment insulation layer with a layer of glass wool or polyurethane foam, thermal conductivity, temperature resistance. The temperature detected by the thermocouple, platinum resistance thermistor mode and high accuracy. ? Safety devices :: humidifier dry protection, independent over-temperature protection, water protection, compressor overload, overcurrent protection, the refrigerant pressure protection switch, over-current circuit breakers, earth leakage protection ? Subsidiary functions: alarm display, power failure protection function, the upper limit temperature alarm function, timer function (automatic start and automatic stop), self-diagnostic function, the function curve records show Technical parameters: Laboratory space size: 5500 * 4750 * 2800mm Laboratory air flow rate: not more than 0.25m / s Laboratory ambient temperature: 20 ± 2 ° C (ambient temperature measurement points should be selected in the mid-point of the measured water heaters and the test angle wall or from the measured electric water heater at 1m, whichever is smaller, and located in the measured electric water heater half the height of the ambient temperature should be stable under the conditions of measurement) The laboratory Relative humidity: no more than 85% (measured under stable conditions) Control system: the balance of temperature & humidity control system Temperature range: R.T +15 ~ +25 ℃ Humidity range: 50 ~ 85% RH Temperature fluctuation: ± 0.5 ° C Temperature deviation: ≤ ± 2.0 ° C Humidity deviation: ± 5.0% RH (≤ 85% RH) Heating time: ≥ 2 ~ 3 ℃ / min, cooling time: ≤ 1 ° C / min. Cooling method: mechanical compression of single-stage cooling (air-cooled condenser) Power supply: AC380 ± 10V 50 ± 0.5Hz three-phase five-wire |
