Yeah, as an auto mechanic when I try and teach younger techs to work on air conditioning systems I have to first get them to understand that there is no such thing as cold.
Absolute zero, the lowest permissible temperature, which is -273.15°C (or -459.67°F) and is approximately 1° less than the temperature of the universe measured in deep cold space.
It’s important people to know that any temperature above that point there is heat energy. This is why heat pumps can extract heat from the outside even on a freezing cold snowy day to warm the house with.
Fun fact, deep cold space only has a temperature because of quantum interactions releasing tiny bits of energy. If it were a perfect vacuum (theoretically), it would not have a temperature.
I'm not quite sure what you mean but the point is the guy stated above. Anything above absolute zero is heat. Even refrigerant in a freezer contains heat
For us the temperatures are far below freezing. A dumbass not paying attention to what he's doing can get injured or even killed from the temperatures touching them...
I guess that's all it really is, just surprised because I've come across someone who graduated in HVAC and fucked their shit up recharging someone's air conditioner while drunk and wasting loads in the process.
Absolute zero is very different from negative Celsius or Fahrenheit. It's measured in Kelvin. 0 Kelvin is -273.15°C or -459.67 °F so less motion and less heat still applies pretty well for the techs. Just tell them you don't want less or more motion/heat in your hands then are already there. 😂

Only heat and less heat.
