There is a saying, “Heat flows downhill.” This means that heat always flows from a warmer to a cooler solid, liquid, or gas. The greater the ∆T, the faster the heat flow. Heat flow is a basic principle of refrigeration - in fact, of all HVAC work. For example, in th...

In principle, they all obey a universal law, similar to the familiar Ohm's law, which can be expressed, in general terms as: the rate of transport (i.e., the quantity transported per unit time) is proportional to the driving force and inversely proportional to the resistance of the ...
