Special Chiller for Low Temperature Bench Test

Special Chiller for Low Temperature Bench Test

The low-temperature bench test is an important test link of the fuel cell system. It undertakes the key task of simulating the low-temperature start-up performance, and the requirements for supporting equipment are relatively strict. Otherwise, the low-temperature test of the fuel cell will be abnormal and cause serious consequences!

Among them, the high-performance low-temperature chiller is an important equipment for providing cold source, which can provide low temperature for the bench test, so that the engine oil, intake air, coolant and fuel are in a low-temperature environment, and the specified test target is completed.

Let’s introduce to our friends what characteristics the chiller used in the low temperature bench test should have.

First look at the content of the low temperature bench test:

It usually includes: cold immersion test, bench simulation operation, engine cold machine calibration test, cooling test and other requirements, low temperature bench test system, can establish ultra-low temperature system, provide process requirements for engine oil, intake air, coolant and fuel Low temperature, test its operation. Taking the cold immersion test as an example, the chiller can provide independent controllable temperatures for coolant, fuel, and engine oil, which can be set to -10ºC, -7ºC, 0ºC, 10ºC, 20ºC, and the control accuracy is ±0.5ºC.

The low-temperature chiller takes -20°C frozen water and stores it in the coolant low-temperature energy storage tank. At the beginning of the cold immersion test, the chilled water pump draws low-temperature frozen water from the energy storage tank, and then adjusts the test temperature through the coolant temperature control system. It then enters the engine cooling pipeline, provides coolant with a target temperature of -10°C, and finally returns to the energy storage tank again.

In the bench test cold immersion test, there are high requirements for the chiller, compressor configuration, electric control system, heat exchange system, protection function, and the control system is at least a PLC control unit, which can communicate with the system and automatically control.

Let’s look at the characteristics of the special chiller for bench test:

1. The chiller can run 24 hours a day without interruption, meeting continuous production testing;

2. The intelligent PLC control of the electric control system of the chiller has been optimized in terms of hardware design, which can accurately control the water temperature in real time;

3. The international famous brand compressor is used, with stable performance and low failure rate, and can automatically adjust energy.

4. The refrigeration unit is equipped with a variety of protection devices, such as motor protection, circuit protection, pressure protection, chilled water antifreeze protection, etc.;

5. Non-standard chiller models, explosion-proof, stainless steel chillers, etc. can be customized for testing institutions.

6. Optional RS485 communication interface and provide communication protocol to realize remote control.

It can be seen that the low-temperature bench test has high requirements for chillers. As a fuel cell manufacturer or testing organization, you should carefully select the type of refrigeration equipment, and you should not choose it arbitrarily, and you should combine it with your own needs.
