How does a humidity chamber simulate a variety of temperature and humidity natural environments

A humidity chamber often referred to as a temperature and humidity chamber , is appropriate for testing products like electrical equipment, home appliances, food, trolleys, vulcanized rubber, plastic rubber, metal, and other materials. A range of natural settings in terms of temperature and humidity can be simulated in the chamber. The goal of the entire humidification process is to raise the water vapor’s working pressure in the chamber. This article will discuss what temperature and humidity chambers are, the specific detail of the humidity chamber LISUN produces, its uses, how it works, and some frequently asked questions about the product.

To imitate the temperature of the outside environment, a temperature and humidity chamber is employed. It is also known as a thermal chamber or an environmental chamber. The IEC60068-2-1 (GB/T2423.1), IEC60068-2-2 ( GB/T2423.2), IEC60068-2-78, IEC60598-1, GB/T2423.17, GB/T5170.2, and GB/T5170.5 standards are all adhered to by LISUN’s humidity chamber. The CFL/LED that complies with IES LM-80-08, electricity items, automobiles, home appliances, and mobiles are tested in the climatic chamber.

A temperature chamber is used as a test box to imitate the settings that a product may encounter while in use while evaluating the effects of different environmental variables on a product, component, part, or assembly. The conditions in the environmental chamber are managed by computer monitors, which can be configured to swiftly change the conditions or slow them down to make them last for a long time.

To offer the most accurate information about a product’s performance in the kinds of circumstances that it would encounter in typical use, testing specifications and standards are specified. The testing standards are frequently stricter than the conditions in which the product would ordinarily be used.

Product detail
The test chamber for temperature and humidity is constructed of SUS304 steel. Ultra-fine glass fiber and polyurethane hard foam are used to create the thermal insulation layer. The high temperature ageing silicone rubber sealing strip is used on the heat-insulated doorframe. The German Siemens PLC and the Korean TEMI display in English and Chinese make up the climate chamber’s temperature controller. Through RS-232, it can communicate with a PC. The humidity precision is 0.1 percent RH and the temperature accuracy is 0.1°C. The independent heating system makes use of a nickel-chrome electric heater, and the temperature sensor inside the chamber is platinum PT100/MV.

The refrigeration system is entirely enclosed, single-stage, air-cooled, and the compressor is from France’s TECUMSEH brand, allowing you to receive after-sales service from numerous other nations. Additionally, a multi-blade centrifugal wind wheel and a temperature- resistant, low-noise air-conditioned motor are used in the circulation system. Electric leakage, short circuit, over-temperature, motor overheating, compressor pressure, overload, and over-current protection are all included in the safety prevention system. The product’s operating voltage is AC 380 V, 10% 3 phases, 50 Hz/60 Hz, and its working temperature and relative humidity are 5 °C to +30 °C and 85 % RH, respectively.

How do environmental chambers work?
Depending on their intended application, test chambers employ a variety of techniques to establish and maintain the ambient conditions. We will briefly cover the cooling, heating, humidity, and salt spray functions performed by LISUN environmental chambers since they are commonly used.

A/C & Refrigeration
The ability to control extremely low temperatures exists in test chambers (like -70 degrees Celsius). When boost cooling is used to lower temperatures more quickly, for as with liquid carbon dioxide or liquid nitrogen, it may be necessary to cool quickly during stress tests .

Heating
In contemporary test chambers, air is heated using electric heating systems to deliver exact, regulated results. Utilizing independent, quick-response nichrome heaters with ceramic cores, this is accomplished. Standard models can reach temperatures of 120 degrees Celsius and well over with a precision of +/-0.5 degrees. When heating and cooling, it’s important to keep in mind the test chambers’ desired degree of performance. High and low temperatures are attainable with standard versions. These extremes or rate changes, meanwhile, might be above their capacity without damaging the smaller compressors. When testing your product, always consider how quickly it absorbs heat. The expectations for performance will be impacted by this.

Humidity
Each test chamber has been fitted with vapor steam generators that are specifically attached to supply humidity. They require a well prepared water source for humidity levels between 20 and 95 percent relative humidity (RH). To remove unwanted humidity and quicken the pulldown process, a mechanical dehumidifying system is usually used. Some test chambers are made to maintain strict humidity control even when the temperature changes. Users that need to attain relative humidity levels as low as 5%. RH compressors use desiccant air dryers to test chambers. When testing your product, always consider how quickly it absorbs heat. The expectations for performance will be impacted by this.

Salt Mist
The salt spray is created by preparing and maintaining a salt solution in a tank. Compressed air is then used to drive it through a nozzle, creating a fine mist in the test chamber. During testing, the product is completely visible because to its transparent walls .

What is a humidity chamber used for?
At various stages of the product development process, businesses test the effects of the environment. For newer businesses, it is an essential part of the proof of concept and prototyping. Testing expedites their time to market by validating their most recent concepts for experienced users. While it is important to emphasize that you should spend more time identifying potential weak areas throughout research and development, different phases necessitate different test profiles. The cost of repairing them is much higher, both in terms of loss of production time and financially.

Research is essential for the technological and engineering tasks required to advance the design and development of products. Businesses in virtually every industry employ R&D to develop, produce, and distribute cutting-edge items. Environmental test chambers are employed in many R&D projects.

Some of them are designed for lab research, testing to identify or assess product alternatives, developing and testing pre-production prototypes, and other similar purposes. The most frequent tests are those that examine a product’s shelf life. Businesses simulate the lifespan of a product through a procedure called extremely accelerated life testing (for example, a change of five degrees in the test chamber is equivalent to two years in a real-world environment) (HALT).

The goal is to identify the alleged “failure point” of products so that firms can set expectations or, if necessary, concentrate on a different design that proves to be more durable. The more time, money, and effort you put into R&D testing, the more confident you will feel about moving to production.

Production
Companies use a variety of production testing methodologies depending on the products and industry. For instance, producers of defibrillators perform accelerated stress testing on each device that exits the manufacturing line (HASS). The goal of HASS testing is to show that the product reaches the failure point identified during HALT testing without malfunctioning. Every single one must function flawlessly and according to schedule since they all have the potential to save lives.

In several industries, individual product testing is indeed required. Companies frequently test goods that have just left the assembly line. However, some test multiple product batches at once in an effort to save time and money. The concept is the same regardless of the method. You must make sure your products are reliable and of high quality before making them available to the wider market. The testing also confirms the time and money put into R&D.

Quality Control
Does the product perform as it ought to? That is what you are attempting to discover during quality testing. Quality assurance and control provide a guarantee for the caliber of a product. Unique environmental quality standards apply to a wide range of products, parts, and components in a number of industries. These standards may be imposed by governmental or commercial bodies, or they may be a significant element of the firm’s design or manufacturing specifications same.

Reliability Checks
At this stage, the environment actually matters. Electronics manufacturers in particular test their products to ensure that they work in a variety of environments, including high and low humidity levels and extreme temperatures. Their expectations and consumer recommendations are guided by the results. Reliability testing also reduces the possibility of unplanned, expensive product breakdowns after the product has been released. If you can identify the HALT testing weak areas and ensure that the products leaving the factory consistently surpass those limitations, you can enter the market safely.

FAQs
What is the quality difference between LISUN’s humidity chamber and other brands in China Market?
Other brands simply offer empty conditions but LISUN offers a low temperature, such as -60°C warranty under a 200W bulb with warmth. Additionally, the business has chosen a maintenance-free electronic humidity sensor from Finland. The competitors are still using dry ball devices, which are simple to dry and problematic after 3-6 months of use. Customers can connect a water pipe to the water purification system that is included in LISUN’s humidity chamber to give direct water supply.

Competitor firms’ humidity chambers require manual water addition. Last but not least, the Schneider and Omron brands of solid state relays and the well-known brand AC contactor have been used as the main electrical connecting elements in the LISUN temperature chamber. If they fail, it is simple for an individual to locate in his local market. Competitor brands, however, combine them with almost local Chinese labels.

If the humidity chamber won’t turn on, what should you do?
The equipment is powered by a three-phase, 380V, and 50 Hz power source. Note that the voltage, frequency, and phase order are all in the proper order. Change the phase sequence of any two live wires to restart it if it still won’t turn on.

What is the use of the temperature alarms?
Two over temperature guards are present in the high and low temperature humidity box. In order to prevent dry burning in the boiler when there is no water present, one is employed. Typically, it can be set to 120 degrees, and if it is, an alert will sound. The test chamber makes use of one. The over temperature protector is set to roughly 180 degrees if your test chamber’s maximum temperature is 150 degrees, and if it is surpassed, an alarm will sound. First, make sure the temperature that has been set by the temperature protectors all around is accurate. If the warning persists, speak with a LISUN engineer.
