Chiller capacity comes from a simple heat balance: Q (kW) = coolant mass flow (kg/s) × specific heat (kJ/kg·K) × temperature drop (K). For water, cp is about 4.18 kJ/kg·K. Dividing by 3.517 converts kW to tons of refrigeration (1 TR = 12,000 BTU/h).
Water-cooled chillers reject heat to a cooling tower at a lower condensing temperature, so they use less power per TR and are the usual choice for large, continuous loads. They need tower make-up water, blowdown and water treatment to control scale, corrosion and Legionella.
Air-cooled chillers need no cooling tower and suit water-scarce sites and smaller loads. Their capacity and efficiency drop as ambient temperature rises, so they should be rated at the site's actual summer peak — not at a standard 35 °C catalogue condition.
Below about +5 °C, water must be replaced with a glycol or brine solution to prevent freezing. Ethylene glycol has better heat transfer but is toxic; propylene glycol is preferred where incidental contact with food or pharmaceutical product is possible.
Glycol lowers heat transfer and raises viscosity, so chiller ratings, pump heads and heat-exchanger areas must be corrected for the actual concentration. The freeze point of the solution should sit several degrees below the lowest operating temperature, and concentration should be checked periodically.
A cooling tower is specified by its flow, its range (hot water in minus cold water out) and its approach (cold water out minus ambient wet-bulb temperature). Towers can only cool towards the wet-bulb, never below it, so selection must use the site's summer design wet-bulb rather than the dry-bulb temperature.
A closer approach needs a much larger tower; approaches of around 3–5 °C are common for process duty. Counter-flow FRP towers suit most process loads, with drift eliminators and a water treatment programme to protect condensers and heat exchangers.
Refrigerant choice now affects the life of the equipment, not just its performance. R-22, an HCFC, is being phased out under the Montreal Protocol. HFCs such as R-134a, R-407C, R-410A and R-404A are being phased down under the Kigali Amendment, under which India's HFC consumption is scheduled to freeze in 2028, with reductions from 2032.
Higher global-warming-potential refrigerants such as R-404A face the earliest pressure. Natural refrigerants — R-290 (propane) for smaller packaged units and R-717 (ammonia) for large industrial plant — have very low GWP, but bring flammability or toxicity considerations that the plant design and safety studies must address.
Pharmaceutical process cooling — reactor jackets, crystallisers, condensers and solvent recovery — needs tight temperature control, sanitary or closed-loop secondary circuits, and documentation to support qualification.
Where chillers or pumps sit in a classified hazardous area, motors and electrical equipment must be flameproof or otherwise suitable for the zone, with PESO approval for use in India. For exothermic reactions, the cooling system is also a safety system: its capacity and failure modes should be checked against the reaction's thermal hazard data.
Multiply the coolant mass flow by its specific heat and the temperature drop you need: Q (kW) = flow (kg/s) × cp (kJ/kg·K) × ΔT. Divide kW by 3.517 to get tons of refrigeration. For example, 10 m³/h of water cooled by 5 °C needs about 58 kW, or roughly 16.5 TR, before any design margin.
One ton of refrigeration (TR) is 12,000 BTU/h, or about 3.517 kW of heat removal.
Water-cooled chillers are more energy-efficient because they reject heat at a lower condensing temperature, but they need a cooling tower, make-up water and water treatment. Air-cooled chillers are simpler and suit water-scarce sites, though their efficiency and capacity fall as summer ambient temperature rises.
Ethylene glycol gives better heat transfer but is toxic. Propylene glycol is preferred wherever incidental contact with food or pharmaceutical product is possible. Both reduce heat transfer and raise viscosity compared with water, so pumps and heat exchangers must be sized for the actual glycol concentration.
R-22 is an HCFC being phased out under the Montreal Protocol, so new systems use HFCs such as R-134a, R-407C or R-410A, or natural refrigerants such as R-290 and R-717. Existing R-22 systems can be retrofitted to a suitable replacement refrigerant.
