water cooling systems
These systems are directly evaluating water cooling through chillers, which are devices that contain all parts of the refrigeration cycle inside them to cool the water, and cold water is distributed to different places through pipes, and the cooling is transferred to the air in the rooms through the fan units located inside the building And there are two main types of these systems according to the way in which the heat is expelled from the coolers or in particular from the condensers, in which the heat is expelled to the surrounding air, and in which the heat is expelled to the water so that cooling towers are usually installed to expel heat from the condensers to it.
air fans
Ventilation fans are used to circulate air in buildings or homes. This type of ventilation is known as mechanical ventilation in which fans or blowers are used to create air movement. The other way to ventilate the house is to use natural ventilation where the air is moved by natural forces Exhaust fans work by sucking in hot or humid air from a small, localized area, allowing fresh air to enter from somewhere else (perhaps a door or vent) to replace it. Then the warm air drawn in using an exhaust fan is drawn through the duct system and expelled outside
HVAC pumps
Most air conditioning pumps are of the centrifugal type. The most common is the type that has a horizontal direction for water to enter the pump and exit perpendicular to a common base with the motor connected to a spindle with an easy-to-disassemble connection to facilitate maintenance work.
These pumps ensure the flow of water at a constant speed in the heating or cooling circuit. An auxiliary pump can ensure the flow of water to the secondary circuit and a two-way valve to control the amount of water for each area to be cooled.
