home work ?
School starts next Monday..so cant ask the instructor before then.
I'm on a section on the refrigeration process.
The book says that the refrigerant is 100 F high pressure on the condenser side of the metering device. IT passes through the metering device and becomes low pressure and 40 F. passes through the evaporator and picks up heat....and so on.
MY ????? is what makes it drop 60 F just from passing through the metering device? Is it the latent heat of vaporization? The flash gas absorbs the heat? or just going from high pressure to low pressure drops the temperature?
I am so confused.
