Name: Walk-in constant temperature and humidity room Model: HKW-235 Brand: Huakai Huakai testing equipment Technology Co., Ltd., Dongguan, Guangdong Province, on the 4th address Ming Leung Ka Wah Road Shijie Town, Dongguan City, Village Product Information 1. temperature and humidity chamber for the detection electronics, electrical appliances, food, automotive, rubber, plastic rubber, metal and other products, can simulate different environmental conditions of high temperature and high humidity, low temperature, humidity, etc., but with the program is easy to operate and learn to control and high accuracy of sentinel control system to provide the best test performance. Dongguan Huakai small series, the following briefly the temperature and humidity chamber operating points; first when making environmental testing, the required performance of the test sample, test conditions, test procedures and test techniques to be familiar to the test equipment used technical performance to be familiar with the equipment to be constructed understand, especially the operation and performance of the controller should be familiar with. Also read the test equipment operation manuals, to avoid operational errors caused by the normal operation of the test equipment is not causing damage to the test sample, the test data is incorrect. Secondly, a reasonable choice of test equipment. In order to ensure the normal test, the test sample should be depending on the situation, select the appropriate test equipment, we must maintain a reasonable proportion between the effective volume of the climatic chamber and the chamber of the test sample. Heating test for the test sample, the volume should be less than one tenth of the effective volume of the chamber. For non-heat test sample volume should not exceed one fifth of the effective volume of the chamber. If you have any questions need advice, please contact our professional staff, we look forward to your call. Because the focus of the testing equipment produced more than ten years, so professional in this industry. 2.

Because the focus of the testing equipment produced more than ten years, so professional in this industry. 1), the test system should be advanced and reasonable structure design, manufacturing process specifications, look beautiful, generous. 2) The main function of chamber components should be configured using the world famous (high gold content), the principle of advanced and reliable technology, noise and energy to get the best control. 3) supporting parts and assembly good match, the main function components using imported parts should have the international advanced level, to improve the safety and reliability of the equipment to ensure that users long, high-frequency requirements. 4), the device should have good operability, maintainability, good temperature stability and durability, good safety performance, do not pollute the environment and endanger human health. 5), the control cabinet all wires should have special equipment for the printing and production of serial number, the line is clear at a glance. Second, the major technical indicators (can be customized) 1, indoor studio clearance dimensions: 5.5m (W) × 2.8m (H) × 5.5m (D) 2, Dimensions approximately: 3 to the actual subject, observation window size: Perspective window demisting size: 2: Width 300 × height 450mm; 4, temperature range: -70 ℃, -40 ℃, -20 ℃, 0 ℃, 150 ℃ temperature fluctuation: ± 0.5 ℃ temperature uniformity Degree: ± 2 ℃ 5, Humidity: 20% ~ 98% RH humidity fluctuation: ± 2% RH humidity uniformity: ± 2.5% RH Humidity deviation: ≤ ± 3% RH (> 75% RH) ≤ ± 5% RH (≤75% RH) 6, the heating rate of about: 1 ~ 3 ℃ / min cooling rate of about: 0.7 ~ 1 ℃ / min 7, noise: ≤65dB 8, wind speed, indoor air convection 9 no room to meet the staff including 10 long work, water and sewer: the need for a water circulation system ensures a constant temperature water temperature deviation at ± 1 ℃, the water temperature can be adjusted in the range of 10-30 ℃, you need to configure a faucet, and a sewer (row sink comes with manhole, supply pipes requires the use of the abundance, drain pipe using PVC-C) 11, power supply: 380V ± 10%, the switching device 100A above technical data are run at room temperature 20 ± 5 ℃, relative humidity ≤85 Under% RH, non-linear load chamber conditions, the cooling water temperature is 5-30 ℃, the water pressure in the clean fresh water 0.1-0.3Mpa between the constant temperature and humidity data measured two hours later. Third, the air conditioning system, it works: Forced ventilation circulation, balance thermostat wet: the central control system to zoom According to the collected inside temperature signal, analog / digital conversion, after the non-linear calibration and temperature setpoint (target) to compare the error signal obtained by the PID operation, the output signal is automatically controlled to adjust the output power of the size of the heater, the test chamber heating and heat loss to achieve a dynamic balance, and ultimately achieve the purpose of the thermostat. 2, the air circulation device: plus the long axis centrifugal fans, the long axis of the external drive motor; 3, air heating: special spiral using nickel-chromium alloy heat dissipation area of ??the resistive heater; PID + SSR drive control; 4, the air Cooling: Efficient diaphragm air heat exchanger; 5, when the cabinet is installed balance transom, inside the box to ensure that the working pressure range control at 76 ~ 102Kpa; four, refrigeration systems
