SIZING OPTIMIZ ATION OF A CENTRAL CHILLED WATER SYSTEM by Jon B. Belcher, PE INTRODUCTION Your organization has decided to build a central chilled water plant to supply comfort cooling to several existing and planned future buildings. Among the immediate design decisions as well as sit ing the facilit y and distribut ion system routi ng, your charge is to size the central plant. While sizing …
After the water has been chilled, it is distributed via pumps, pipes, and valves (the distribution system) to the loads, where a heat exchanger—for example, a cooling coil in an air-handler—transfers heat from the air to the chilled
Relief valve sizing methods for chilled water systems are not easy to find. How do you size this small insurance policy, the chilled water pressure relief valve? The following is a sizing method created back in 1996 for a newsletter I called,

As a result, a new chilled water system design has become available. This design is a single loop system with a single set of pumps. Like the primary-secondary system the single loop design has two-way valves in air handlers. This variable flow rate, primary system also eliminates the primary- secondary bypass loop. Existing primary-secondary systems can be converted to this design by …
Chiller manufacturers recommend somewhere between 2-6 gallons per ton for nominal cooling in a typical system. Even higher, 6-10 gallons when temperature accuracy is critical. 1.

A 2-pipe HVAC system is one that uses the same piping alternately for hot water heating and chilled water cooling, as opposed to a 4-pipe system that uses separate lines for hot and chilled water. Two-pipe originated 50 or 60 years ago as a cost-effective way to add air conditioning. The premise was a …

The “HVAC Pipe Sizer – Liquid” application allows you to quickly size a simple pipe system by inputting a number of piping and liquid properties, including hot and chilled water (hydronic). You can specify the total fluid flow in GPM (or L/s) and one of either unit head loss (ft/100ft), pipe internal diameter (inches) or fluid velocity (ft/s) parameters. The results include both the exact and
Chiller savings using condenser- and chilled-water-temperature reset, however, should be balanced against the increase in pumping and cooling-tower energy. This is discussed in Period Four.

The size of the pipe must be such that high speed water flow creates noise and reduce the life of pipes Nshvd.kahsh corrosion due to water flow rate in the pipes should be made to the extent that unjustified increase in the cost of plumbing pipe diameter does not increase.
In a chilled water system the water is cooled down to 40 – 45 o F (4 – 7 o C) by an centralized evaporator, distributed throughout the building in pipes and connected locally to air condition cooling units wherever needed.
