MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202647092879 A) filed by Everllence Se on July 31, 2026, for Method And Control Device For Operating A Heat Pump While Stabilizing A Network Frequency Of An Electrical Power Network.
Inventors include Aho, Tuomo; Jacquemoud, Emmanuel; and Wolscht, Leonhard.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The invention relates to a method for operating a heat pump (10) while stabilizing a network frequency of an electrical power network (15), wherein the heat pump has a first heat exchanger (11), a compressor (12) that can be driven by an electric machine (14) connected to the electrical power network, a second heat exchanger (13), and an expansion device (16), wherein: the first heat exchanger (11) is designed to transfer thermal energy to a process medium; the compressor (12) is designed to compress the process medium downstream of the first heat exchanger; the second heat exchanger (13) is designed to transfer thermal energy of the process medium to a load; the expansion device (16) is designed to expand the process medium downstream of the second heat exchanger; and the heat pump (10) has a device by means of which a volume flow of the process medium can be adjusted. When an actual network frequency of the electrical power network (15) deviates from a setpoint network frequency, in order to stabilize the network frequency, an electrical power consumption of the electric machine (14) is controlled by controlling a rotational speed of the electric machine and/or by changing the volume flow of the process medium in such a way that, at an approximately constant pressure ratio of the compressor (12) and thus at an approximately constant temperature of the process medium in the region of the second heat exchanger (13), the actual network frequency is approximated to the setpoint network frequency.
