A friend gave me some mint, and didn't mention what type it is. How can I tell if it's spearmint, peppermint, apple mint, lemon mint, or some other variety? I googled some pictures, but quite frankly, all the pictures look very similar -- four leaves growing from the center which a textured leaf and a rich, green colour.
A water source air-conditioner or heat pump is a variation of a traditional air source heat pump. The explanation that follows first describes how a cooling-only water source air-conditioner. works. A description of a heat pump (heating and cooling) will follow.
The water pump is a centrifugal pump driven by the serpentine belt connected to the crankshaft. The pump helps to circulate coolant from the radiator through the engine removing heat from the engine and allowing the coolant to reduce its temperature by returning to the radiator.
