All Type of A/C Units
Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building. ...
There are four main types of HVAC systems. There are split systems, hybrid systems, duct-free systems, and packaged heating and air systems
The central air conditioning system found in most homes are a "split system". This typically means there is a compressor unit (outside) and an indoor coil, installed on your furnace inside the home
A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool equipment, Cooled liquid passes through pipes in a building and coils in air handlers or through fan-coil units, which help dehumidify the air. Generally, chillers are air and water cooled.
There are three different types of chillers :(1) air, (2) water, and (3) evaporative condensed chiller. There are four subcategories in each of the above categories for industrial chillers: (1) reciprocating, (2) centrifugal, (3) screw driven (4) and absorption chillers.
Ventilation fans are used to circulate the air in the buildings or houses. This type of ventilation is known as mechanical ventilation in which fans or blowers are used to create movement of the air. The other way to ventilate a house is using the natural ventilation where the air is moved by natural forces.
Exhaust fans work by sucking hot or humid air out of a small, localized area, allowing fresh air to enter from elsewhere (perhaps a doorway or vent) in order to replace it. The warm air that's drawn out using an exhaust fan is then pulled through a ducting system and expelled outside.
Most pumps used in HVAC are a centrifugal type. One of the most common, is the base or frame mounted end suction pump. With this pump there's a frame upon which the motor and pump are mounted, and both shafts are connected by coupling, which makes servicing the equipment much easier.
Constant speed pumps drive the flow through the primary (chiller or boiler) loop. A separate secondary pump delivers variable flow to the secondary loop and two-way valves are applied to control flow through each zone.
Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducts commonly also deliver ventilation air as part of the supply air. ... A duct system is also called ductwork
The duct, or air distribution, system used in cooling and heating your home is a collection of tubes that distributes the heated or cooled air to the different rooms. ... All of the air drawn into the return duct(s) is conditioned and should be delivered back through the supply registers
The most common types of rigid ductwork are: Sheet metal ducts. These are the kinds of ducts you've seen in films – usually with an action hero crawling through them! Galvanized steel and aluminum are the most common materials for sheet metal ducts
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature.
There are three main types of cooling towers that are defined by how water or air pass through them. These types include crossflow, counterblow, and hyperbolic. There are also two varieties classified solely on airflow, known as induced draft and passive draft cooling towers.
Chilled Water Piping Works
Chilled water is a commodity often used to cool a building's air and equipment, especially in situations where many individual rooms must be controlled separately, such as a hotel.
Chilled Water: PVC Pipe. Chilled Water systems contain and transport cool water throughout industrial and commercial... Polyvinyl Chloride (PVC) piping is the most widely used plastic piping material.
AHU’s & FCU’s
An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. ... Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork.
A fan coil unit (FCU) is a simple device consisting of a heating and/or cooling heat exchanger or 'coil' and fan. It is part of an HVAC system found in residential, commercial, and industrial buildings.
FCU is often observed to be noisier than the AHU. AHU v/s FCU AHU and FCU are both included in the HVAC system. The latter is an acronym that describes multiple systems of heating, ventilating and air conditioning. AHUs are usually connected to a central HVAC system whereas an FCU can function or be installed itself.
