• Accelerated Environmental Testing Technology

  Mar 21, 2025

  Traditional environmental testing is based on the simulation of real environmental conditions, known as environmental simulation testing. This method is characterized by simulating real environments and incorporating design margins to ensure the product passes the test. However, its drawbacks include low efficiency and significant resource consumption.   Accelerated Environmental Testing (AET) is an emerging reliability testing technology. This approach breaks away from traditional reliability testing methods by introducing a stimulation mechanism, which significantly reduces testing time, improves efficiency, and lowers testing costs. The research and application of AET hold substantial practical significance for the advancement of reliability engineering.   Accelerated Environmental Testing Stimulation testing involves applying stress and rapidly detecting environmental conditions to eliminate potential defects in products. The stresses applied in these tests do not simulate real environments but are instead aimed at maximizing stimulation efficiency.   Accelerated Environmental Testing is a form of stimulation testing that employs intensified stress conditions to assess product reliability. The level of acceleration in such tests is typically represented by an acceleration factor, defined as the ratio of a device's lifespan under natural operating conditions to its lifespan under accelerated conditions.   The stresses applied can include temperature, vibration, pressure, humidity (referred to as the "four comprehensive stresses"), and other factors. Combinations of these stresses are often more effective in certain scenarios. High-rate temperature cycling and broadband random vibration are recognized as the most effective forms of stimulation stress. There are two primary types of accelerated environmental testing: Accelerated Life Testing (ALT) and Reliability Enhancement Testing (RET).   Reliability Enhancement Testing (RET) is used to expose early failure faults related to product design and to determine the product's strength against random failures during its effective lifespan. Accelerated Life Testing aims to identify how, when, and why wear-out failures occur in products.   Below is a brief explanation of these two fundamental types.   1. Accelerated Life Testing (ALT) : Environmental Test Chamber Accelerated Life Testing is conducted on components, materials, and manufacturing processes to determine their lifespan. Its purpose is not to expose defects but to identify and quantify the failure mechanisms that lead to product wear-out at the end of its useful life. For products with long lifespans, ALT must be conducted over a sufficiently long period to estimate their lifespan accurately.   ALT is based on the assumption that the characteristics of a product under short-term, high-stress conditions are consistent with those under long-term, low-stress conditions. To shorten testing time, accelerated stresses are applied, a method known as Highly Accelerated Life Testing (HALT).   ALT provides valuable data on the expected wear mechanisms of products, which is crucial in today's market, where consumers increasingly demand information about the lifespan of the products they purchase. Estimating product lifespan is just one of the uses of ALT. It enables designers and manufacturers to gain a comprehensive understanding of the product, identify critical components, materials, and processes, and make necessary improvements and controls. Additionally, the data obtained from these tests instills confidence in both manufacturers and consumers.   ALT is typically performed on sampled products.   2. Reliability Enhancement Testing (RET) Reliability Enhancement Testing goes by various names and forms, such as step-stress testing, stress life testing (STRIEF), and Highly Accelerated Life Testing (HALT). The goal of RET is to systematically apply increasing levels of environmental and operational stress to induce failures and expose design weaknesses, thereby evaluating the reliability of the product design. Therefore, RET should be implemented early in the product design and development cycle to facilitate design modifications.     Researchers in the field of reliability noted in the early 1980s that significant residual design defects offered considerable room for reliability improvement. Additionally, cost and development cycle time are critical factors in today's competitive market. Studies have shown that RET is one of the best methods to address these issues. It achieves higher reliability compared to traditional methods and, more importantly, provides early reliability insights in a short time, unlike traditional methods that require prolonged reliability growth (TAAF), thereby reducing costs.

• Analysis of Accessory Configuration in Refrigeration Systems for Environmental Test Equipment

  Mar 11, 2025

  Some companies equip their refrigeration systems with a wide array of components, ensuring that every part mentioned in textbooks is included. However, is it truly necessary to install all these components? Does installing all of them always bring benefits? Let's analyze this matter and share some insights with fellow enthusiasts. Whether these insights are correct or not is open to interpretation.   Oil Separator   An oil separator allows most of the compressor lubricating oil carried out from the compressor discharge port to return. A small portion of the oil must circulate through the system before it can return with the refrigerant to the compressor suction port. If the system's oil return is not smooth, oil can gradually accumulate in the system, leading to reduced heat exchange efficiency and compressor oil starvation. Conversely, for refrigerants like R404a, which have limited solubility in oil, an oil separator can increase the saturation of oil in the refrigerant. For large systems, where the piping is generally wider and oil return is more efficient, and the oil volume is larger, an oil separator is quite suitable. However, for small systems, the key to oil return lies in the smoothness of the oil path, making the oil separator less effective.   Liquid Accumulator   A liquid accumulator prevents uncondensed refrigerant from entering or minimally entering the circulation system, thereby improving heat exchange efficiency. However, it also leads to increased refrigerant charge and lower condensation pressure. For small systems with limited circulation flow, the goal of liquid accumulation can often be achieved through improved piping processes.   Evaporator Pressure Regulating Valve   An evaporator pressure regulating valve is typically used in dehumidification systems to control the evaporation temperature and prevent frost formation on the evaporator. However, in single-stage circulation systems, using an evaporator pressure regulating valve requires the installation of a refrigeration return solenoid valve, complicating the piping structure and hindering system fluidity. Currently, most test chambers do not include an evaporator pressure regulating valve.     Heat Exchanger   A heat exchanger offers three benefits: it can subcool the condensed refrigerant, reducing premature vaporization in the piping; it can fully vaporize the return refrigerant, reducing the risk of liquid slugging; and it can enhance system efficiency. However, the inclusion of a heat exchanger complicates the system's piping. If the piping is not arranged with careful craftsmanship, it can increase pipe losses, making it less suitable for companies producing in small batches.   Check Valve   In systems used for multiple circulation branches, a check valve is installed at the return port of inactive branches to prevent refrigerant from flowing back and accumulating in the inactive space. If the accumulation is in gaseous form, it does not affect system operation; the main concern is preventing liquid accumulation. Therefore, not all branches require a check valve.   Suction Accumulator   For refrigeration systems in environmental testing equipment with variable operating conditions, a suction accumulator is an effective means to avoid liquid slugging and can also help regulate refrigeration capacity. However, a suction accumulator also interrupts the system's oil return, necessitating the installation of an oil separator. For units with Tecumseh fully enclosed compressors, the suction port has an adequate buffer space that provides some vaporization, allowing the omission of a suction accumulator. For units with limited installation space, a hot bypass can be set up to vaporize excess return liquid.   Cooling Capacity PID Control   Cooling capacity PID control is notably effective in operational energy savings. Moreover, in thermal balance mode, where temperature field indicators are relatively poor around room temperature (approximately 20°C), systems with cooling capacity PID control can achieve ideal indicators. It also performs well in constant temperature and humidity control, making it a leading technology in refrigeration systems for environmental testing products. Cooling capacity PID control comes in two types: time proportion and opening proportion. Time proportion controls the on-off ratio of the refrigeration solenoid valve within a time cycle, while opening proportion controls the conduction amount of the electronic expansion valve. However, in time proportion control, the lifespan of the solenoid valve is a bottleneck. Currently, the best solenoid valves on the market have an estimated lifespan of only 3-5 years, so it's necessary to calculate whether the maintenance costs are lower than the energy savings. In opening proportion control, electronic expansion valves are currently expensive and not easily available on the market. Being a dynamic balance, they also face lifespan issues.

It provides large parts, semi-finished products, and large temperature and humidity test environment space for finished products. It is suitable for the test equipment with large quantity and volume. Some are installed on the interal chamber or door, and some are not installed. Where is the best place to install light bulbs? In fact, the high and low temperature test chamber lighting has advantages and disadvantages no matter where it is installed. If the lighting is installed in the broadcast room, you can clearly see the condition of the entire broadcast room and observe the product at any time. The lamp is installed on the door, and when the user conducts the double 85 test or the high temperature and high humidity test, the humidity is not easy to invade the lamp, and the lamp is not easy to damage, which can greatly reduce the after-sales service fee. However, its observation field is very small, can only observe the near attractions, customers observe the product is not very convenient. If the lamp is installed on the right side of the internal chamber, it is recommended to be completely sealed to prevent moisture intrusion to ensure the long-term stable operation of the lamp. If it is installed on a door, it is recommended that the viewing window be trapezoid, so that you can have a wider field of view. Of course, some corporate customers choose not to install lighting when purchasing high and low temperature test chambers to reduce production costs and later management costs. However, customers can not observe products at any time when doing tests, and they can not meet the needs of different customers who want to observe products.

• Composition and Application of Temperature and Humidity Regulating Chamber

  Dec 24, 2024

  Composition and Application of Temperature and Humidity Regulating Chamber Temperature and humidity regulating chamber is a device that controls the ambient temperature and humidity. It can provide a stable temperature and humidity environment to meet the requirements of a specific product or experiment. Temperature and humidity regulating chamber is usually composed of a control system, a heating system, a cooling system, a humidity control system and a circulation system. In terms of working principle, temperature and humidity regulating chamber realizes temperature control through the control system to control the operation of the heating system and the refrigeration system. When the temperature is too low, the heating system starts and provides heat to raise the temperature; When the temperature is too high, the refrigeration system starts and absorbs heat to reduce the temperature. In this way, the temperature regulator can maintain a stable operating temperature. The humidity control system of temperature and humidity regulating chamber is used to maintain a proper humidity level. When the humidity is too low, the humidity control system releases water vapor to increase the humidity; When the humidity is too high, the humidity control system absorbs the excess humidity to reduce the humidity. With precise humidity control, temperature regulators ensure that the ambient humidity is within the ideal range. Temperature and humidity regulating chamber is widely used in practical applications. Taking the pharmaceutical industry as an example, some drugs have high requirements for temperature and humidity during processing and storage. If the ambient temperature and humidity are not effectively controlled, the quality and stability of these drugs will be affected. The temperature regulator can provide a stable working environment to ensure the quality and efficiency of the drug. In the food industry, Temperature and humidity regulating chamber also plays an important role. For example, in the chocolate manufacturing process, the control of temperature and humidity directly affects the texture and taste of chocolate. The temperature regulator accurately controls temperature and humidity, ensuring that the chocolate production process meets standards and produces quality products. Temperature and humidity regulating chamber is also widely used in electronic, chemical and other industries. In the electronics industry, temperature and humidity control is very important for the production and storage of electronic components. In the chemical industry, some chemical reactions have high requirements for temperature and humidity, which can provide a stable and safe working environment.
