Integrating negative temperatures around -196°C with a specific system or process such as a liquid nitrogen (LN2) Dewar typically involves using the Dewar as a storage vessel to keep the substance being cooled at the desired temperature.
The Dewar is a container that uses vacuum insulation to keep the liquid nitrogen cold and prevent heat transfer from the environment. It can be used to store biological samples, chemicals, and other materials that require very low temperatures.
To integrate negative temperatures with a specific system or process using a Dewar, you would typically need to connect the Dewar to the system or process in some way. This could involve using a transfer hose or tubing to move the cooled substance from the Dewar to the system, or by immersing the system in the liquid nitrogen.
It's important to note that working with extremely low temperatures such as those achieved with liquid nitrogen can be dangerous, and appropriate safety measures should always be taken to prevent accidents and injuries. Additionally, the specific process of integrating negative temperatures will depend on the application and the equipment involved, so it's important to consult with experts in the field for guidance and advice.
The reason why the industry did not invent freezers of negative temperatures around -196°C (equivalent to liquid nitrogen) may be due to several factors, including:
-
Cost: The equipment required to achieve such low temperatures can be expensive and may not be feasible for many industries.
-
Safety concerns: Working with extremely low temperatures can be dangerous, and the equipment required to achieve them needs to be properly maintained and operated to avoid accidents.
-
Efficiency: Freezing products to such low temperatures may not be necessary for most applications, and it may be more efficient and cost-effective to use other methods to achieve the desired results.
-
Quality control: Freezing products to extremely low temperatures may affect their quality, texture, and taste, making them less appealing to consumers.
Overall, the decision to use specific equipment or techniques in the industry is typically based on a balance of factors such as cost, safety, efficiency, and quality control.
