The Test Room EXII Technology is the new design to protect the Test Room against the possible explosion when the Test Object carries Explosive Refrigerant. With the re-designed EXII devices, the Test Room can allow to test the Test Object that carries the A1, A2 & A3 Safety Graded Refrigerant. Basically, the allowed refrigerant includes (but not limit to) the R290, the R32, the R600A, the R170, and the R1270.

The EXII technology (also management process) estimates the safety status of the Test Room based on the possible Explosive Refrigerant be used in a Test Room. Accordingly, the protection method will be designed to avoid safety hazard. Controlling methods may include (not limited to ) the control of the leak of the refrigerant and the isolation of the possible fire and ignition.

The technology is a robust protection mechanism and the protection is as careful as to each component of the Test Room. Besides the control for the Test Object as described above, other protection method such as zoning of test of different refrigerant, monitoring of refrigerant leak, powering of EXII Graded device, and ducting of fresh air are also necessarily equipped to the Test Room.

This technology is very important to the new Test Rooms required to test with the Explosive Refrigerant. Is can be used to the Test Room of the Air Conditioner, the Fridge, the Freezer, the Heat Exchanger, the Refrigeration, the Refrigeration Compressor & Valve etc.

The Energy Saving Technology changes the working mechanism of the Air Handling Unit in the Test Room and successfully, it improves the Test Room with less energy costs. The technology can slash the power consumption by a re-designed cooling/heating system which reduces the excess heat and humid added to the Test Room. With this innovated system, the electric as well as the power costs will drop siginificantly.

The designed mechanism is easy to understand and however, the system is a combination of the Variable Speed Compressor, the Variable Speed Fan, the Heat Recovery System, the Heat Bypass Technology, and the Evaporation Pressure Technology. With the different Test Room system design, any 2 to 5 of the above energy saving items will be integrated into the system (with smart PID control) to save the energy.

Our company has owned 18 patents of the Energy Saving technology. Some of the patents are shown as follows.

• Independant Control of Humid & Temperature for the Air Handling Unit (Patent Number: ZL201110025178.8)• Energy Saving Type of the Humid & Temperature Condition (Patent Number: ZL201220097376.5)• A Humid & Temperature Control System with the High Control Efficiency & Wide Control Range (Patent Number: ZL20140171003.7)

The Software is the ‘brain’ of the Test Room and it controls all the operations of the Test Room.

As a very important component of the Test Room, the software can provide the following functions.

• Data Acquisition• Data Control• Test Management• User Management• Device Management• Calibration Management

• Data Analysis• Report Export• Diagram Display• Test Monitor• Data Exchange Port• Remote Control

The software is developed by our own programme team with the backend software LabView.
