Overall Structure

The box body is fully welded in the factory, the structure is firm, the installation is fast, the construction period is short, and the equipment can be moved easily in the later stage. There is no need to remove any refrigeration unit or electronic control unit.

Inner Box Material

SUS #304 stainless steel plate

Outer Box Material

Iron plate paint

Storage Rack

Stainless steel SUS304# adjustable spacing storage rail 2 groups, grid storage rack 2 sheet. Each layer bears 20kg. The sample rack can be adjusted up and down as needed.

Thermal

Insulation Material

100mm rigid polyurethane foam, fire-resistant and fire-proof, in line with environmental requirements. The interlayer between the stainless steel of the inner chamber and the outer shell is filled with polyurethane, which can simultaneously insulate and strengthen the strength of the inner and outer chambers.

Sealing

The door of the test box is sealed with silicon rubber strip, which is resistant to high and low temperature, anti-aging, and has good sealing performance

Observation Window

There is a large-scale vacuum observation glass with 3 layers of heat and sweat prevention attached to the door. During any test, there is no frost or condensation on the surface.

Lighting device

There is a lighting lamp on the window.

Test Hole

There is one Φ160mm hole on the left and right sides of the body, and two soft plugs. It can be used for external test power line or signal line.

Pressure Balance Port

The pressure balance port is used to balance the pressure inside and outside the storehouse. When heating, the internal pressure is prevented from generating too much outward thrust on the door. When cooling, the door is prevented from inward opening. Normally closed, automatically open when the pressure difference is large

Heater

Using stainless steel barrel heating wire

Humidifier

Split humidifier design, convenient for maintenance

Water Tank

Self-made stainless steel water tank with mechanical automatic water inlet function and water shortage alarm function

Temperature Sensor

Imported platinum PT100 temperature sensor with high accuracy

Humidity Sensor

the electronic humidity sensor imported from Switzerland

Wind Turbine

2 motors, stainless steel with long shaft; multi-wing fan blade aluminum alloy wind wheel (SIROCCO FAN), special adjustable 100-page air circulation system

Box Door

Movable door, 6 holes are opened on the door according to the requirements, the door can be removed for activities, 2 sets of hook locks are designed on the left and right sides of the door

Air Supply System：

Special Feature of

Air Supply

The air is transported by centrifugal wind wheels, and the wind direction of the air outlet louvers is adjusted to fully ensure the uniformity in the box

Circulation Motor

Use 380V asynchronous motor

Wind Wheel

Multi-blade centrifugal circulation fan, high and low temperature resistant aluminum alloy blades

Compressor

Adopting German semi-hermetic compressor

Condenser

Barrel condenser (water-cooled condenser)

Expansion valve:

(1) Electronic expansion valve. Servo control of refrigerant flow (that is, cooling without heating, heating

Uncooled “static balance” technology)

(2) As a new type of control element, the electronic expansion valve has already broken through the throttle mechanism

Concept, it is an important part of the intelligence of the refrigeration system, and it is also the optimization of the refrigeration system.

Important means and guarantees for real realization.

(3) Product features:

1. Fully enclosed design, stepper motor drive

2. From very close to fully open in a very short time

3. High accuracy and extremely long life

4. The flow rate changes linearly with a wide cooling capacity range

5. Continuous cooling adjustment, no liquid hammer in the refrigeration circuit

6. The motor is integrated with the valve, with high reliability, and the ceramic valve plate and valve port parts are wear-resistant

damage

Main Advantage

1. Realize the active control of the refrigeration system, not the fixed proportional adjustment of the original thermal expansion valve.

control. The output can be adjusted in advance and optimized for different modes and operating conditions.

2. Due to the closed-loop control feedback front end of the electronic expansion valve is the temperature and pressure dual sensor high

Responsive direct control, which can provide the best evaporator liquid supply, so that the refrigeration system

The wider working range achieves excellent cooling capacity output.

3. Energy saving: full-range self-adaptation of the electronic expansion valve + active adaptation to adjust the cooling capacity

Out, making the system more energy efficient.
