Question on thermodynamics

Former Community Member
Former Community Member
Hello everyone, I have a question on the energy cost of compressing gas.

I didn't find a community about thermodynamics, so I post the question here..


When gas absorbs heat. its volume increases from v1 to v2. When we compress the volume of the same gas from v2 to v1, does the energy required equal to the heat it absorbs? Does the temperature affect the energy required?

    The 90/20 deg C is just an example.. Whatever the average running temperature is, it should be higher than outdoor temp due to the joule heat. As long as the energy required by cooling system is smaller than the reduced heat, we are saving.


    As you mentioned, a number of circuit are designed to share the load, thus there's fault tolerant ability in the electric network. Without cooling system, the power cable still can be broken, am I right?

    The health check and management is widely used in telecom networks. Is it possible to used to check the status of the cooling system?


    It's a good point that cooling system may break the power transmission. But can we identify the root cause and fix it?
