working of chiller plant and air handling unit.
What is Central A/c plant ? The central air conditioning plants or the systems are used when large buildings, hotels, theaters, airports, shopping malls etc are to be air conditioned completely. The window and split air conditioners are used for single rooms or small office spaces. If the whole building is to be cooled it is not economically viable to put window or split air conditioner in each and every room. Further, these small units cannot satisfactorily cool the large halls, auditoriums, receptions areas etc.
Type of central Air Conditioner plant 1- Direct expansion or DX central air conditioning plant 2- Chilled water central air conditioning plant a- Water cooled b- Air cooled
Parts of Chilled water central A/C plant
1- Compressor
2-Condenser
3-Throttling valve in chiller unit installed in plant room
4-Evaporator
5- Drier filter
6- Accumulators
7-Air handling unit installed in floors
8-Cooling tower
installed on the roof
1-Refrigerant 2-Water 3-Brine solution
Working of Chilled water central a/c plant It has the plant room where all the important units like the compressor, condenser, throttling valve and the evaporator are housed. After passing through the evaporator, the brine solution gets chilled and is pumped to the various air handling units installed at different floors of the building. The air handling units comprise the cooling coil through which the chilled brine flows, and the blower. The blower sucks hot return air from the room via ducts and blows it over the cooling coil. The cool air is then supplied to the space to be cooled through the ducts. The brine solution which has absorbed the room heat comes back to the evaporator, gets chilled and is again pumped back to the air handling unit.
