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.
Refrigerators and air-conditioning systems are really just one-way heat pumps (or a half-heat pump). Because they move heat rather than generate heat, heat pumps can provide up to four times the amount of energy they consume in electricity, according to the U.S. Department of Energy. heat pump is equipment that uses a refrigerant to move heat from one place to another. During the summer, a heat pump captures heat from inside a home and transfers it to the outdoor air through a condensing unit.
