Air Handling Unit or Air handler OR AHU

Air Handling Unit FUNCTION: The AHU is designed to circulate the air in the area after passing it through 10/20 micron fresh air filter, 10/5 micron pre filter, 5/3 micron fine filter, 3/1 micron fine filter and 0.3 micron HEPA filter to achieve a clean class as per desined. The air in-take and out-take of the system is designed to maintain certain degree of pressure gradient in the area as per the requirement. To generate the required CFM and static pressure, appropriate motor capacity and blower is considered. The major components of the air handling units are briefly described as below: 5.0   6.0 AIR HANDLING SYSTEM:           Supply Blower : Supply blower is provided in the unit to supply air in the working area. This blower is belt driven by a motor. The blower takes the air from the atmosphere and delivers it to the working areas through air distribution network.   AIR CONDITIONING SYSTEM:        ...

Industrial Chiller on Vapour compression refrigeration cycle

Industrial Chiller 1)What is Chillar:- Industrial process chiller is a machine which remove heat from liquid by vapour Compression,absorption and adsorption cycle. This Chilled liquid further used for cooling in Air Handling unit, For Reactor,For heat exchanger and for lots of equipment who's need to be cool. Industrial Process Water Chiller       We are going to see Industrial process Water Chiller on a vapour compression cycle,Chiller maintain temperature of water at 4℃, this Chilled water required in Air Handling unit for maintaining temperature and humidity of Air. 2)Main components of Chiller:- In every chiller there are four most important parts are Compressor , Condenser , Expansion valve and Evaporator. -Compressor:-  When we start the chiller compressor compress the vapour Refrigerant Due to the compression, pressure and temperature of vapour Refrigerant increases. Compressor circulates the Refrigerant through the all system, there is no any equipment...
