Structure of high low temperature humidity test chambers

1.Structure

The backside of the working chamber is the air duct, the upper part of the air duct is an outlet, the lower part is a return air outlet, equipped with a long axial flow air supply motor, a centrifugal fan blade, a heater and a refrigeration evaporator inside.

Beside working chamber, it is the control panel, the temperature humidity control chambers adopt programmable LCD touch screen controller for easy operation.

Programmable controller advanatages:

·7 inch Japan programmable touch screen controller

·Set temperature point under fix value mode or programs mode

·Temperature set point and realtime temperature curve display ·100 groups program with 999 segment memory; each segment 99Hour59Min

·Test data can be downloaded as required through RS232 interface

The left side of control panel is electrical cabinet, all core electrical components are Schneider and other well-known brands.

Testing hole (Cable Access Port):φ50mm lead hole is located at the right side of the chamber, with reinforced soft rubber plug and cover.

The Lower part is the refrigeration system, it includes refrigeration pipelines, compressors, evaporator, motor/ fans and water tank.

The bottom is high-quality heavy duty PU castors with brakes.

2.Heating and Refrigeration System

High low temperature humidity test chambers adopt forced air convection to perform heating and cooling tests.

To realize temperature humidity control, the test chamber should be able to carry out two functions: heating and cooling, uniform temperature also must be evenly distributed inside the testing area, Climatest Symor® makes it possible to achieve a high degree of temperature uniformity in the whole testing area.

High low temperature humidity test chambers adopt mechanical cooling system and mechanical heating system to conduct testings on products:

Mechanical heating system consists of electric heating elements positioned near the ventilation system, so that the heated hot air is delivered into the testing zone from air inlet, then come out from air outlet, meanwhile, there are centrifugal fans located at the back of the air inlet, so as to blast the hot air to reach better uniformity.

Mechanical cooling system consists of a closed circuit system, with the following main components:

·Control valve

·Condensor

·Evaporator

·Compressor

The refrigeration system in a thermal test chamber is classified to be single stage and double stage, the single stage is adopted with temperature -40℃ and above, and double stage (also called cascade system) is with temperature below 40℃.

3.Humidification and Dehumidification System

Humidifying Tube: Nickel-chromium naked heater

Shallow groove humidification method

Humidifier control method: Contact-less equal-period pulse-width modulation, SSR (Solid State Relay)

Water level automatic compensation and water shortage alarming system

Water Supply adopts automatic watering System, Circulating water supply together with water filter.

Application:

Constant Temperature Humidity Climatic Chamber, Temperature Humidity Controlled Chamber 50L-1000L
High low temperature humidity test chambers are used to test auto parts performance under extreme environment, such as cold, heat, damp and dry conditions, this test chamber is widely applied in electronics, electrical appliances, communication, automobile, plastic products, chemicals, aerospace and more.

New energy vehicles, also known as alternative fuel vehicles, meets explosive growth from 2021. It is a strategic measure to address climate change and promote green development. However, environmental reliability testing becomes indispensable in the R&D process before mass manufacturing new energy vehicle, below is the common climatic tests:
