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.
Geothermal heat pumps can tap into this resource to heat and cool buildings. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger.
