Renewable Heating And Cooling

Industrial Process Heat Technologies and Applications: Text Version of the Diagram

The diagram shows nine different renewable heating and cooling technologies and four common types of end uses or applications related to industrial process heating. The diagram is arranged by “working temperature” range, so that users can see which technologies align well with certain end-use applications. Each technology and application will link to a page with more information. All temperature ranges are approximate and not necessarily applicable to every individual situation. The diagram above shows technologies and applications in terms of their working temperature, which is the required temperature of the water or heat transfer fluid within the renewable heating/cooling system. The working temperature is not necessarily the same as the final temperature of the end product (the air or water that is ultimately being heated). For example, some commercial space heating systems require a working temperature of 100-200 degrees Fahrenheit, even if they are only heating the building to around 70 degrees Fahrenheit.

The diagram includes the following nine technologies with approximate temperature ranges:

The diagram includes the following four end-use applications with approximate temperature ranges:

  • Agricultural space and media heating: approximately 32 to 220 degrees Fahrenheit
  • Cooking, pressurization, sterilization, and bleaching: approximately 130 to 230 degrees Fahrenheit
  • Industrial distillation, concentrating, and drying or kilning: approximately 170 to 320 degrees Fahrenheit
  • Chemical or other high-temperature processes: approximately 200 to more than 400 degrees Fahrenheit
