Title:
ENERGY STORAGE SYSTEM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/005080
Kind Code:
A1
Abstract:
The present invention provides an energy storage system control method capable of ensuring that cold storage and heat storage can be performed more effectively under the same electrical energy consumption conditions. The energy storage system comprises an energy storage heat exchanger which is connected to a refrigerant circulation circuit by means of a bypass refrigerant circuit, an energy storage tank which is connected to the energy storage heat exchanger by means of a first energy storage circuit through which a first heat exchange medium flows, and an environmental energy exchange device which is connected to the energy storage tank by means of a second energy storage circuit through which a second heat exchange medium flows, and the control method includes: acquiring an environmental temperature and a temperature of an energy storage medium in the energy storage tank; comparing an energy storage efficiency of the environmental energy exchange device and an energy storage efficiency of an air conditioning device on the basis of the environmental temperature and the temperature of the energy storage medium in the energy storage tank; and performing energy storage utilizing the one of the environmental energy exchange device and the air conditioning device having the greater energy storage efficiency.
