Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has unveiled a brand new warmth pump meant to be used in industrial processes with heating and cooling necessities.
The German analysis institute mentioned it developed the system in collaboration with the Bavarian Center for Applied Energy Research (ZAE Bayern) and German-based industrial tools supplier Mafac E. Schwarz GmbH & Co. KG, beneath the umbrella of ETA of Existing Facility analysis mission funded by the Federal Ministry for Economic Affairs and Climate Protection (BMWK).
Fraunhofer ISE’s contribution to the mission consists of offering a particular propane (R290) refrigeration circuit that reportedly doesn’t exceed the utmost restrict of 150 grams of propane. “Thus, the warmth pump might be operated independently of the security necessities that apply to indoor warmth pump installations with flammable refrigerants,” it mentioned in a press release.
The consortium examined the warmth pump along with an present industrial cleansing machine that was beforehand solely powered by grid electrical energy. This machine often operates in a two-shift mode with 5 days of manufacturing per week and 48 weeks of manufacturing per 12 months.
The check confirmed that the warmth pump can obtain a mixed heating and cooling efficiency of 5.6, the place the Fraunhofer ISE is a greater efficiency than that obtained by the machine when used with grid energy.
“The energy necessities for heating the method water and for heating the air circulation for drying are lower in half, whereas the facility used to warmth contemporary water is diminished by 80%,” the analysis institute mentioned. “By recirculating the exhaust air, greater than 10,000 liters of contemporary water might be saved yearly, due to a brand new kind of condensation unit that successfully cools the exhaust air course of, permitting the accessible cooling from the warmth pump that can be utilized to wash the machine alongside the method.”
The consortium added that the novel warmth pump system can be utilized in different industrial processes with a temperature vary of fifty C to 70 C.
