WebCycle of heat transfer. The cycle starts with refrigerant. It is a liquid entering the expansion device. When it passes through, the sudden drop in pressure makes it expand cool and turn into a gas. When refrigerant flows around the evaporator coil, it absorbs and removes heat from the food stored inside. Web14 apr. 2024 · The main difference between cooking on a propane griddle vs. a gas gill is how heat is applied to the food. In a grill, the heat is transferred directly to the food via the propane flame. As grease drips down, the flames rise and provide the often-sought-after flame-grilled taste. However, the griddle is similar to…
