Poaceae have hollow stems called culms plugged at intervals by solid leaf-bearing nodes. Grass leaves are nearly always alternate and distichous (in one plane), and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem and a blade with entire (i.e., smooth) margins.oaceae have hollow stems called culms plugged at intervals by solid leaf-bearing nodes.

Air conditioning system components consisting of Condensing Unit, Evaporator Coil, Refrigerant line. How air conditioning works is kind of a mystery to many of us. Furnaces are easy to understand, they heat air and blow it around your home in ductwork.
An air conditioner is designed to dehumidify and remove heat from an area. The cooling is done using a simple refrigeration cycle. A condenser is a component of the basic refrigeration cycle that removes heat from the system. The condenser is the hot side of an air conditioner.Condensers are heat exchangers that can transfer heat to air or heat to fluid (such as water or glycol) to carry the heat away. An air handler, or air handling unit (often called an AHU), is used to condition and circulate air as part of an HVAC system.An air handler usually contains a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.n air conditioner is designed to dehumidify and remove heat from an area.
