4、 Box structure

1.The box adopts an integral structure.

2.The inner side of the box adopts1.0mm SUS304B stainless steel plate, with the outer side coated with 1.0mm cold-rolled steel plate,3.Insulation materials are used*Fine glass insulation cotton.

4.The door seal adopts double-layer silicone rubber sealing material.

5.The observation window is made of multi-layer conductive film tempered insulating glass, with a size ofTo prevent glass frosting at low temperatures, a 200 × 300mm built-in design is specially designed*The heating wire is wrapped around and equipped with lighting fixtures to provide illumination for observation.

6.There are plugs on the side of the boxThe test hole with a diameter of 50mm is made of silicone rubber with low foaming material, which can withstand high and low temperatures and has insulation effect.

7.There is an air conditioning cabinet installed at the rear of the box workshop, in which equipment such as evaporators, electric heaters, fans, and fan volutes are installed.

8.The temperature sensor is placed at the air outlet.

9.The air supply method inside the test chamber is upward air supply and downward return air supply.

5、 Heating and cooling system

1.The heater adopts a porcelain frame nickel chromium wire electric heater, which has low thermal inertia and long service life. Controllable pulse duty cycle output by the instrumentPID signal, controlled by solid-state relay, ensures smooth and reliable control.

2.Low temperature refrigeration adopts FranceTaikang "fully enclosed compressor unit. Other refrigeration components such as RANCO from the United States, SPORLAN, ALFALAVAL from Switzerland, DANFOSS from Denmark, CASTEL from Italy, and Eginomiya from Japan*Mouth brand products. UseR404A environmentally friendly refrigerant.

3.To ensure the safe operation of the system, high-voltage control, overpressure, overload and other protection systems need to be installed in the system. At the same time, in order to monitor the operation of the system, a high voltage meter is installed at the high voltage end to monitor the operation of the system.

4.The cooling capacity adjustment adopts the split flow method.

6、 Control system

1. Control system: The electrical control system is composed of a LCD touch screen temperature and humidity controller and Schneider Electric components.

2. controlThe device adopts a fully Chinese menu operation mode.

3. *Small display resolution0.01℃。

4. runMethod: Fixed value and program execution.

5. controlManufacturing method: continuousPID control.

6. Set up 120 sets of programs, each set of programs*Grand Setting99 steps, each program group can be connected.

All loops*many999 cycles, partially looping*many99 times.

7. Power outage recovery settings, including: program termination after power outage, program continuous running from breakpoint after power outage.
