4.Structure section of machine body

The chamber consists of several section: chamber body, control system, refrigeration system, heating system, humidation system, wind system, raining system, lighting system and so on.

Chamber body

a. With integrated structure, the chamber consists of up left part as working room, up right part as electric controller which is convenient to control, down part as compressor cooling group, sample holder rotation device, Xenon lamp condensation water box, water pump and other executive devices.

b. Inner wall of chamber adopts international SUS304# material.

c. Temp. insulation material is polyurethane foam and ultra-fine fibre glass, with good temp. insulation result, no frost and condensation on the external surface of chamber.

d. condensate water outfall set at the bottom of chamber

e. Environmental heat-resistance silicon sealing tape as the material of door frame.

f. Viewing window with eye-protective film on its surface to protect eyes from being injured by Xenon lamp.

external chamber body

a. Seal of door adopts the double-layer of refined silicone rubber with reliable sealing effect and no aging or hardening phenomenon under high or low temperature.

b. Single door (embedded handle);

c. Viewing window, antifrost device and lamp equipped on the door

viewing window

Size:25 cm W × 30 cm H;equipped with Anti-radiation hollow glass

5.Electric control section of chamber

a. As the core part of chamber

b. Air pressure switch as the main switch to control the main circuit;

c. Safety measures for electric section: it warns and cut electricity automatically after tested the action from following protection devices:

a) overheat protection in working room

b) lockage of phase, leakage protection

c) overcurrent protection of motor

d) overpressure/overload protection of cooling machine

e) short out/overload protection of heater, humidifer

f) fusing protection of fuse

6.Working section of chamber

Condensation section of compressor.

A.Cooling system: as the core part of cooling system, we adopt one set of compressor of Tecumseh from France in this case to ensure the cooling requirement in the working room.

B.For adjustment technology and design of cooling system, we take an efficiency processing way to ensure the adjustment for the cooling amount and consumption of cooling system under the normal running, to make the failure rate down to the economical statue.

C.Cooling evaporator: it locates in interlayer at one side of chamber which ventilate by force from blast motor to exchange heat fast.

D.Cooling method of cooling system: forced air cooling Cooling refrigerant:Environmental R404a;

Heating system

a. Heating method: heating directly in the chamber;

b. Stainless steel heating tube used, with fast and stable heating to keep temperature in the working room from rapid change. It with corrosion resistance, anti-high-low temperature, no leakage and other advantages.

c. With SSR (solid relay)output control, without noise, reliable working, long service life time, fast switching, low interference from outside, and easy operation etc..

Rain system.

it consists of nozzle, solenoid valve, water-supplying and connecting pipe.

Lighting system.

It consists of xenon lamp, lamp cover, lamp contactor and other controlling parts. Energy compensation is got by adjusting samples distance, pressure and current.

Wind system 

It locates in the interlayer at the back of chamber, there are heater, fan blade, evaporator, PT100 temperature samples sensor etc.. when wind machine running, the air is intaken to the channel from working room, and blow out from the bottom after cooled; the air exchanged in the working room with samples is intaken again to the channel and mix; after several circulation, it will reach the purposed temperature, and ensure the high index of temp. and humid in the chamber at the same time.

Cooling dehumidification system

take the compressor of world brand Tecumseh from France to keep constant temperature, decrease the humidity in the working room and cool the xenon lamp.

Humidification

Steam generator: to generate steam from water

Water level control: control the water inlet by solenoid valve, and water level by liquid level switch to provide the signal for water-supply and warning.

Air circulation section

Cycling channel and winding machine inside the chamber, it uses the high efficiency cooling machine and energy adjusting system, efficiency heat exchange to reach the aim of temperature change, which also improves the airflow and heat exchange between airflow, heating and humidification, as a result, it improves the humidity uniformity in the working room.
