The Fundamentals of Heating and Cooling Degree Days, Part 1

That's where heating degree days and, to a lesser extent, cooling degree days come in. What is a degree day? A degree day is a combination of time and temperature difference (ΔT). The basic idea behind it is to give you an indication of how much heating or cooling a building might need. Emphasis on the "might" there.

2.2.1 Keep the chilled water supply temperature as high as .

percent of input energy per degree Fahrenheit (or about four percent per degree Celsius) that the chilled water temperature is raised. This number applies to all types of chillers, with minor variations. Figure 1 shows how COP improves with increasing chilled water temperature, for a typical chiller. This simple procedure applies to virtually .

Disadvantage of Higher Delta T in Chilled Water Systems

This increases chiller energy use (kWh), chiller peak power (kW), and increased wear and tear on the chiller. So, continuing the example, let's avoid the disadvantage of lowering the supply temperature, and instead achieve a delta T of 15 degrees by increasing the return temperature by 5 degrees. Now we will have a supply temperature of 44'F .

Knowledge — Superheat and Subcooling - Ravti

Heating degree day - Wikipedia

Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature.The heating requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location.. Related measurements include the cooling degree day (CDD), which .
