Everyone prefers to be cool in cool environment. Water cooled chillers are better because of the cooling which they provide at a lesser cost & power consumption also as compared to ACs . But do remember that they are few cities which contain beaches in surrounding and thos places an water coller chiller is never sufficient. Even in gulf places like dubai, muscat the heat is so much that even in bathrooms and kitchens you find ACs because one cannot stay there without that. Lots of new technoligies being adopted and nowadys ACs are coming at ECONOMICAL way both by money and energy consumption. As per your comfort and requirements please adopt anyone but even think of green building concepts also.

For bigger capacity of HVAC load , i feel Water Cooled chillers are always benificial from energy saving point of view . Initial investment will be higher but ROI will be @ 7-8 years of operation of plant. For the plants upto 300 TR of total load , air cooled chillers are prefered.

For larger proccss unit  Water cooled chillers  are  essential like centralised air condition system of a mall or office building.But in smaller units ,air coolled chillers can be used. So it totally depends on the reqirements.

I, agree with Mr Ashok and Mr,Bundi,but still my view is that of the worst case the water chillers have the edge.

Factors favouring water cooled chillers:

  • For heavy to medium loads.
  • Greater efficiency. Though air cooled chillers are available with matching efficiency but they need huge space and large amount of heat is generated.

Efficiency is a strong favour on the side of water chillers as large units bleed a lot to heat losses anyway...

With what ever disadvantages  Water cooled  chiller systems have, I am for it as it delivers the required temperature at the user end.

Now I would throw the discussion to the respectable forum to air their arguements.

Chiller plants upto 800 KWr in capacity and operating for less than 2000 hrs per year, it is advisable to go in for Air cooled Chiller systems. The desirable transition point form Air cooled to water cooled starts at aout 400 KWr for plants operation for more than 8000hrs per year or approximately 900 KWr and below 2000hrs of operation. The ecomonic cross over point has an imprecise range which warrants project specific LCC ( life cycle costing) analyis representing particular site conditions.

Following factors favour Air cooled chillers

  1. Suitable for smaller loads.
  2. When the conditions to be achieved are not very severe.
  3. In cold climates where water will freeze.
  4. Saves electricity since cooling tower and condenser are avoided.
