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.

Incubators are used for the growth of microorganisms in many fields, including pharmaceuticals, agricultural, environmental, food, and industrial microbiology; public health; basic research; and education.

Biochemical Oxygen Demand (BOD, also called Biological Oxygen Demand) is the amount of dissolved oxygen needed – demanded – by aerobic biological organisms to breakdown organic materials present in a given sample at certain temperature over a specific time period.

BOD incubators are normally rated in the range of 20°C to 60°C.

WIST -BOD incubator is different for normal incubator. Incubation is the length of time in which humidity, temperature, among other environmental factors are utilized to provide the required growth and development level of microbial culture. Therefore, an incubator is a device which allows the incubation process to occur.
