Refrigeration and Airconditioning!
Whenever and wherever a high rise building is being constructed, the issue of air conditioning is an innate part of planning. Things being considered are sizing of the air conditioning units, total loads to be handled, and whether or not a centralized unit is to be used, or individual air-con units, or a mixed design. The ultimate verdict in this will usually be determined based on certain assumptions, which may involve level of occupancy and frequency of occupancy, and the size of the spaces that are to be used at the same time. In a centralized air conditioning strategy, decisions have to be made as to air cooled condensing units or water cooled condensing units, and the maker of the entire chiller systems.
There are many well known makers and suppliers of chillers and HVAC systems. To evaluate the selection, one must look into the available capacities, type of compression systems, refrigerant in use, local availability of follow up service after sales, efficiency of the units, energy consumption, acquisition cost, and total life cycle cost, considering operating materials and supplies cost, and warranty provisions. It is very easy to just jump into a particular design and supplier on the basis of apparent cost, and similarity in design, not knowing the hidden costs, and trade-offs. In this regard, it is advisable to consult a mechanical engineer in this practice and to require each supplier to propose their basic design proposal for a particular installation.
