Comparison of Climatic Test and Environmental Test

Climate environment test -- constant temperature and humidity test chamber, high and low temperature test chamber, cold and hot shock test chamber, wet and heat alternating test chamber, rapid temperature change test chamber, linear temperature change test chamber, walk-in constant temperature and humidity test chamber, etc. They all involve temperature control.

Because there are multiple temperature control points to choose from, the climate chamber temperature control method also has three solutions: inlet temperature control, product temperature control and "cascade" temperature control. The first two are single-point temperature control, and the third is two-parameter temperature control.

Single point temperature control method has been very mature and widely used.

Most of the early control methods were "ping-pong" switch control, commonly known as heating when it's cold and cooling when it's hot. This control mode is a feedback control mode. When the temperature of the circulating air flow is higher than the set temperature, the electromagnetic valve of refrigeration is opened to deliver cold volume to the circulating air flow and reduce the temperature of the air flow. Otherwise, the circuit switch of the heating device is switched on to directly heat the circulating air flow. Raise the temperature of the air stream. This control mode requires that the refrigeration device and heating components of the test chamber are always in a standby working state, which not only wastes a lot of energy, but also the controlled parameter (temperature) is always in an "oscillation" state, and the control accuracy is not high.

Now the single-point temperature control method is mostly changed to the universal proportional differential integral (PID) control method, which can give the controlled temperature correction according to the past change of the controlled parameter (integral control) and the change trend (differential control), which not only saves energy, but also the "oscillation" amplitude is small and the control accuracy is high.

Dual-parameter temperature control is to collect the temperature value of the air inlet of the test chamber and the temperature value near the product at the same time. The air inlet of the test chamber is very close to the installation position of the evaporator and heater in the air modulation room, and its magnitude directly reflects the air modulation result. Using this temperature value as the feedback control parameter has the advantage of quickly modulating the status parameters of the circulating air.

The temperature value near the product indicates the real temperature environmental conditions suffered by the product, which is the requirement of the environmental test specification. Using this temperature value as the parameter of feedback control can ensure the effectiveness and credibility of the temperature environmental test, so this approach takes into account the advantages of both and the requirements of the actual test. The dual-parameter temperature control strategy can be the independent "time-sharing control" of the two groups of temperature data, or the weighted two temperature values can be combined into one temperature value as a feedback control signal according to a certain weighting coefficient, and the value of the weighting coefficient is related to the size of the test chamber, the wind speed of the circulating air flow, the size of the temperature change rate, the heat output of the product work and other parameters.

Because heat transfer is a complex dynamic physical process, and is greatly affected by the atmospheric environment conditions around the test chamber, the working state of the tested sample itself, and the complexity of the structure, it is difficult to establish a perfect mathematical model for the temperature and humidity control of the test chamber. In order to improve the stability and accuracy of control, fuzzy logic control theory and method are introduced in the control of some temperature test chambers. In the control process, the thinking mode of human is simulated, and the predictive control is adopted to control the temperature and humidity space field more quickly.

Compared with the temperature, the selection of humidity measurement and control points is relatively simple. During the circulation flow of the well-regulated humid air into the high and low temperature cycle test chamber, the exchange of water molecules between the wet air and the test piece and the four walls of the test chamber is very small. As long as the temperature of the circulating air is stable, the circulating air flow from entering the test chamber to exiting the test chamber is in the process. The moisture content of wet air changes very little. Therefore, the relative humidity value of the detected air at any point of the circulating air flow field in the test box, such as the inlet, the middle stream of the flow field or the return air outlet, is basically the same. Because of this, in many test chambers that use the wet and dry bulb method to measure humidity, the wet and dry bulb sensor is installed at the return air outlet of the test chamber. Moreover, from the structural design of the test box and the convenience of maintenance in use, the wet and dry bulb sensor used for relative humidity measurement and control is placed at the return air inlet for easy installation, and also helps to regularly replace the wet bulb gauze and clean the temperature sensing head of the resistance PT100, and according to the requirements of the GJB150.9A wet heat test 6.1.3. The wind speed passing through the wet-bulb sensor should not be lower than 4.6m/s. The wet-bulb sensor with a small fan is installed at the return air outlet for easier maintenance and use.

Comparison of Natural Convection Test Chamber, Constant Temperature and Humidity Test Chamber and High Temperature Oven

Instructions:

Home entertainment audio-visual equipment and automotive electronics are one of the key products of many manufacturers, and the product in the development process must simulate the adaptability of the product to temperature and electronic characteristics at different temperatures. However, when using a general oven or thermohumidity machine to simulate the temperature environment, either the oven or thermohumidity machine has a test area equipped with a circulating fan, so there will be wind speed problems in the test area.

During the test, the temperature uniformity is balanced by rotating the circulating fan. Although the temperature uniformity of the test area can be achieved through the wind circulation, the heat of the product to be tested will also be taken away by the circulating air, which will be significantly inconsistent with the actual product in the wind-free use environment (such as the living room, indoor).

Because of the relationship of wind circulation, the temperature difference of the product to be tested will be nearly 10℃, in order to simulate the actual use of environmental conditions, many people will misunderstand that only the test machine can produce temperature (such as: oven, constant temperature wet machine) can carry out natural convection test, in fact, this is not the case. In the specification, there are special requirements for wind speed, and a test environment without wind speed is required. Through the natural convection test equipment and software, the temperature environment without passing through the fan (natural convection) is generated, and the test integration test is performed for the temperature detection of the product under test. This solution can be used for home related electronics or real-world ambient temperature testing in confined Spaces (e.g., large LCD TVS, car cockpits, automotive electronics, laptops, desktops, game consoles, stereos). Etc.).

Unforced air circulation test specification :IEC-68-2-2, GB2423.2, GB2423.2-89 3.31 The difference between the test environment with or without wind circulation and the test of products to be tested:

Instructions:

If the product to be tested is not energized, the product to be tested will not heat itself, its heat source only absorbs the air heat in the test furnace, and if the product to be tested is energized and heated, the wind circulation in the test furnace will take away the heat of the product to be tested. Every 1 meter increase in wind speed, its heat will be reduced by about 10%. Suppose to simulate the temperature characteristics of electronic products in an indoor environment without air conditioning, if an oven or a constant temperature humidifier is used to simulate 35 ° C, although the environment can be controlled within 35 ° C through electric heating and compressor, the wind circulation of the oven and the thermohumidifier will take away the heat of the product to be tested. So that the actual temperature of the product to be tested is lower than the temperature under the real windless state, it is necessary to use a natural convection testing machine without wind speed to effectively simulate the actual windless environment (indoor, no starting car cockpit, instrument chassis, outdoor waterproof box... Such environment).

Comparison table of wind speed and IC product to be tested:

Description: When the ambient wind speed is faster, the IC surface temperature will also take away the IC surface heat due to the wind cycle, resulting in the faster the wind speed and the lower the temperature.

Solar Module Test Project

1. solar module reliability test specification:

The reliability test of the solar module is to confirm the performance of the solar module (early), and the test specifications for the module are mainly IEC61215, IEC61646, UL1703 three test specifications. IEC61215 is suitable for crystalline (Si) modules; IEC61646 is suitable for thin-film (Thin-flm) modules; The UL1703 is suitable for both crystalline and thin film solar modules. In addition, the GB and CNS solar energy specifications are partially modified from the IEC.

2. the relationship and importance of Macro Exhibition and solar energy test projects:

According to IEC61215, IEC61646 test items a total of about 10 (solar module test items corresponding to the general table). Among them, the test equipment manufactured by Hongjian will be used, and the relevant test conditions are temperature cycling (Thermal cycling, 10.11). There are three categories of Humidity freeze (10.12) and Damp heat (10.13), while UL1703 only has two items of temperature cycle wet freezing without the item of damp heat.

3. Thermal cycling test (Thermal cycling)lEC61215-10-11:

Solar module temperature cycle test is used to determine the fatigue, thermal failure, or other stress failure caused by repeated changes in temperature of the module. The current number of temperature cycles is 200 times, and the future trend will be 600 times (according to the test results of the American Association for Renewable Energy [NREL], the power degradation rate of 600 times is greater than 200 times as much as twice).

Through the temperature cycle: defects of the module can be found: crack growth, module cracks, warping, sealing material delamination, point shedding, glass corrosion... Let's wait.

Temperature conditions: Low temperature :-40℃, high temperature :85°C(IEC), 90 °C(UL), the fastest temperature variability (average):100 °C /h, 120 °C /h, relevant measurements need to be carried out during the test (using the Qingsheng solar energy measurement system), the test process needs to measure the module: module surface temperature, voltage and current, ground continuity, insulation... Let's wait.

4. the purpose of the temperature cycle test process through bias:

Temperature cycle test process, the specification requires through bias, the purpose of the test is to make the defective Cell heat to accelerate aging and accelerate failure test purposes, so it needs to be energized above 25℃ during the temperature cycle process, the laboratory in the United States has statistics, It was found that the difference between the failure rate of the solar module with power and without power is as high as 30%, and the experimental data indicates that if there is no power, the solar module is not easy to fail in the temperature cycle environment, so when carrying out the temperature cycle test of the solar cell (Cel)& module, it needs to be matched with a special measurement system.

5. the introduction of wet freezing test lEC61215-10-12:

Description: To determine whether the component is sufficiently resistant to corrosion damage and the ability of moisture expansion to expand the material molecules, frozen moisture is the stress to determine the cause of failure. For the product to be tested, the test stress is high temperature and high humidity (85℃/85%R.H) to low temperature (-40℃ humidity 85%R.H). Maintain to 25℃), and low temperature rise to high temperature and high humidity, rather than 85℃/85%R.H./20 hours, 85℃/85%R.H./20 hours, the purpose of 85℃/85%R.H./20 hours is to let the module surrounding full of water, 20 hours dwell time is too short, is not enough for water to penetrate into the module and junction box inside.

Through wet freezing test: Module defects can be found: cracks, warping, severe corrosion, lamination of sealing materials, failure of adhesive delamination junction box & water accumulation, wet insulation **... Etc.

Test conditions: 85 ℃ / 85% R.H. (h) 20-40 ℃ (0.5 ~ 4 h), maximum heat up 100, 120 ℃ / h, and maximum temperature of 200 ° C/h.

6. Purpose of wet freezing test:

The wet freezing test method is mainly to perform two kinds of damage to the solar module in a snowy environment.

(1). High temperature and humidity (85℃/85%R.H.) drop to -4℃ before 25℃, humidity should be controlled at 85%+5% RH. The purpose of this is to simulate the high humidity sudden change before the snow.

Before the snow, the environment will show a high humidity state, and when the temperature drops to 0℃, the water gas around the module and the junction box sealant will freeze. When the water gas freezes, its volume will expand to 1.1 times of the original, and the destruction method of ice expansion after the water gas penetrates the material gap through the water gas to achieve the purpose of this test. At present, the statistical results of wet freezing have the highest damage to junction box sealant, which will cause junction box degumming and water, and the failure ratio of module is estimated at 7%.

(2). The purpose of heating up from low temperature (-40℃) and humidity (50℃/85%R.H.) is to simulate the temperature rise in the module at sunrise in a snowy climate. Although the outdoor environment is still below 0℃, the solar module will generate electricity when there is light, and because the snow is still on the module, the heat spot effect will occur in the module. The temperature inside the module will also reach 50 ° C.

7. wet heat test (Damp heat) test IEC61215-10-13:

Description: To determine the ability of the module to resist long-term moisture penetration, according to the test results of BP Solar, its 1000 hours is not enough. The actual condition is found that the time to make the module have problems needs at least 1250 hours. According to the current requirements of the specification, the wet heat test process is not powered on, but the future trend is also to be powered on (positive and reverse bias), because it can accelerate the aging and failure of solar cells.

Test conditions: 85℃/85%R.H., time :1000 hours Defects can be found through the wet and thermal test: CELL delamination EVA(delamination, discoloration, bubble formation, atomization, Browning), connection line blackening, TCO corrosion, spot corrosion, Thin-film yellow discoloration, junction box degumming off

Working Principle of UV Weathering Test Chamber

Uv weathering test chamber is a kind of experimental equipment specially used to test the durability and stability of materials and products under ultraviolet radiation. Its working principle revolves around mimicking UV radiation conditions in the natural environment to assess how materials behave when exposed to sunlight for long periods of time. The chamber is equipped with a series of high-intensity ultraviolet light sources that effectively emit ultraviolet light in a specific wavelength range, mimicking the UV-A and UV-B bands of natural sunlight.

During the test, the sample is placed in the test chamber, and ultraviolet radiation will cause changes in the chemical structure of the surface of the material, such as color fading, strength reduction and brittleness increase. At the same time, the test chamber can also be combined with environmental factors such as temperature and humidity for a more comprehensive evaluation of the sample. For example, the humidity control system in the laboratory can simulate the effects of rain and moisture, while the temperature control equipment can reproduce extreme hot or cold conditions.

By exposing the samples to multiple rounds of ultraviolet radiation at different time periods, researchers were able to collect a large amount of experimental data and analyze the aging resistance and service life of the samples in depth. These data play a vital role in material development, product quality control and market demand analysis. In addition, the use of UV weathering test chambers also helps companies anticipate possible performance problems before the launch of new products, so as to make timely adjustments and improvements.

Such tests are not only applicable to plastics, coatings, fibers and other materials, but also widely used in various industries such as automobiles, construction fields and even electronic products. By studying the performance of products in different climatic conditions, companies can improve the competitiveness of their products in the market, but also contribute to the environmental cause, because good weather resistance products usually mean a longer life cycle and less material waste.

In short, UV weathering test chambers play a key role in materials science and product development, not only allowing developers to better grasp material properties, but also for consumers to bring higher quality and more durable products. In the future development of science and technology, with the continuous progress of ultraviolet weathering test technology, we may be able to witness the birth of more new materials and new products, adding more convenience and beauty to our lives.
