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.
A heat pump is a mechanism that is used to extract heat from a source with lower temperature and transfer it into a source with a higher temperature. A heat pump can also be used for cooling, however, only the heating option is needed in radiant heating systems.While air-source heat pumps are very common, geothermal heat pumps are considered to be more efficient for a radiant heating system.The difference between the two pumps is that instead of using outside air, a geothermal heat pump absorbs heat from the earth.hile air-source heat pumps are very common, geothermal heat pumps are considered to be more efficient for a radiant heating system.
