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.
Water source heat pumps (WSHP) transfer heat from where it is not needed to where it is needed, minimizing the amount of energy required for heating/cooling. Standard water source heat pump installations include a boiler and a water cooling tower to add and remove energy from the loop. Geothermal heat pump installations use the ground, a body of water, or the aquifer as a heat exchange medium, eliminating the energy consumed by a boiler or water cooling tower.
