The importance of selecting the correct size chiller is critical. An oversized water chillers will always be a problem - the equipment can not be cooled properly. Large chillers will never be able to run at the most effective level. To determine the correct size of the chiller, and rely on years of continuous, efficient cooling for your application. If you want to help, please feel free to call us. To let you know how to set the dimensions correctly and choose the best solution for your application, use the following formula.

Calculate the "delta T" temperature change between inlet and outlet water. Measuring "delta T" requires a thermocouple or thermometer. Check the water temperature of the inlet and outlet lines and subtract the quantity to calculate the heat added to the water.

Flow rate (GPM). To measure the flow of water, place the flowmeter on the outlet line of the equipment. If it is not available, simply measure the time at which the outlet flow is filled with five gallons of barrels and then calculate the traffic per minute gallon (GPM).

The total lift of the circulating water is inversely proportional to the density of the circulating water and is proportional to the pressure loss of the circulation path. The pressure loss of the circulation path is determined by the pipe diameter, the pipe length, the load shape, and so on.

The temperature and ambient temperature of the circulating water and the temperature of the circulating water are calculated from the special chart of the target unit.

Now that you have these two numbers, calculate your device to launch the BTU.
