Specialized Chambers for Solar Panel Tests

Factors

such as desired throughput, testing methodology, floorspace, and budget will affect the final selection.

Our chambers can be used for the following test methods:

•10.11 Thermal Cycle Test

Requires temperature cycling between 85°C and -40°C,

50 or 200 times.

•10.12 Humidity Freeze Test

Cycling between hot/humid 85°C/85%RH and subfreezing -40°C ten times, with extended soaks at 85/85.

•10.13 Damp Heat Test

A long term, 1,000 hour, test at 85°C/85%.

 

Environmental Chambers for Solar Panel Testing (Walk-in Type)

Specialized Chambers for Solar Panel Tests

From compact type to large type, which can test a lot of full-size PV modules at one time, KOMEG provides various sizes of Solar Panel Walk-in Chambers.

 

Selecting a Chamber

Because the change rates in the specifications are

flexible, you have a choice of selecting a slower system  to save cost and utilities, or a faster system to shorten testing time.

In order for WIST to select the proper heating/cooling subsystems, we will need to know:

• Chamber interior space required

• Total mass of modules and supporting racks to be tested

•Desired heat & cooling rates (Otherwise WIST will quote systems to meet both minimum or maximum rates allowed by IEC.)

Lengthy IEC and UL Tests

All three of the IEC 61215 & 61646 environmental tests WIST chambers are used for can be done in the same test chamber. It may be better, however, to consider multiple chambers to save time and electricity due to the lengths of the tests:

•The temperature cycling test may last up to seven weeks.

•The damp heat test is six weeks long.

A Freeze-Thaw Chamber is a specialized testing equipment designed to subject products or materials to repeated cycles of freezing and thawing. This type of testing is particularly crucial in industries such as pharmaceuticals, biotechnology, and materials science, where products may be exposed to fluctuating temperatures during transportation, storage, or actual use. Here's a description of how Freeze-Thaw Chamber testing works:

1. Temperature Cycling:

   • The primary function of a Freeze-Thaw Chamber is to subject the test specimens to alternating cycles of freezing and thawing. The chamber is equipped with a temperature control system capable of achieving and maintaining both freezing and thawing conditions.

2. Controlled Freezing:

   • The chamber can create and maintain low temperatures, typically ranging from sub-zero to below freezing, replicating cold storage or transport conditions.
   • During the freezing phase, the temperature inside the chamber is lowered gradually or rapidly, depending on the testing requirements.

3. Controlled Thawing:

   • The chamber can simulate thawing conditions by raising the temperature back to ambient or above, mimicking the process of transitioning from frozen to unfrozen states.
   • Thawing is controlled to avoid abrupt temperature changes, which can impact the integrity of the tested materials.

4. Cycle Repetition:

   • Freeze-Thaw testing involves subjecting the specimens to a predefined number of cycles, with each cycle typically consisting of a freezing period followed by a thawing period.
   • The number of cycles and the duration of each phase can be customized based on industry standards, regulatory requirements, or specific product conditions.

5. Monitoring and Control:

   • The chamber is equipped with a monitoring and control system that ensures precise temperature control during both freezing and thawing phases.
   • Temperature sensors continuously monitor conditions inside the chamber, and feedback mechanisms adjust the environmental parameters accordingly.

6. Uniformity of Conditions:

   • Freeze-Thaw Chambers are designed to maintain uniform temperature and humidity conditions throughout the chamber to ensure consistent testing across all specimens.
   • Air circulation systems help distribute temperature evenly, preventing localized variations.

7. Rate of Temperature Change:

   • The rate at which the chamber transitions between freezing and thawing conditions can impact the stress placed on the tested materials. Controlled and defined rates of temperature change are typically specified to simulate realistic conditions.

8. Sample Configuration:

   • The arrangement and configuration of the samples within the chamber can be a critical parameter. Ensuring that the samples are exposed uniformly to the freezing and thawing conditions helps maintain consistency in test results.

9.  

10. Validation and Calibration:

    • Regular validation and calibration of the Freeze-Thaw Chamber are crucial to ensure that it continues to operate within specified parameters. This includes verifying the accuracy of temperature and humidity controls.

11. Material Compatibility:

    • The compatibility of the chamber materials with the tested specimens is considered. Some materials may react differently to freezing and thawing conditions, and the chamber construction should not introduce additional variables.

Freeze Thaw Chamber or Cyclic Temperature stress tests are designed on the knowledge of the product so as to mimic likely storage conditions. The period of cycle is mostly considered 24 hours since the diurnal rhythm on earth is 24 hours. Additionally, the distribution environment can vary greatly, especially when a drug product is shipped between various climatic zones. Seasonal changes, mode of transportation, and the number of drop-off points are also variables that should be considered within the pharmaceuticalsupply chain. Drug products requiring controlled-temperature storage conditions must be distributed in a manner that ensures that the product quality will not be adversely affected. With the exception of short transit times within the same climatic zone, it is virtually impossible to validate a shipping method against all environmental conditions. Therefore, distribution stability studies are designed to generate additional data to complement preformulation development and routine (ICH) Q1A(R2).
