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.
Heat pump is a term commonly used for heat transferring or circulating devices, and machines like refrigerators, air conditioners and freezers. As opposed to the heat engine, heat pump converts mechanical energy into thermal energy. This task is mainly achieved with the help of fluids known as the ârefrigerantsâ. heat pump can be used to either heat the atmosphere or lower the temperatures, depending upon the type of output desired. However, a âfurnaceâ can be used only for heating. Furnaces cannot be considered as a cooling device.
