Description

HEAT PUMP AND HEAT STORAGE FOR HVAC&R SYSTEM CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority from and the benefit of U.S. Provisional Patent Application No. 63/525,084, entitled “HEAT PUMP AND HEAT STORAGE FOR HVAC&R SYSTEM,” filed July 5, 2023, which is hereby incorporated by reference in its entirety for all purposes. BACKGROUND [0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. [0003] A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system may utilize a working fluid (e.g., a refrigerant) that changes phases between vapor, liquid, and combinations thereof in response to exposure to different temperatures and pressures within components of the HVAC&R system (e g., vapor compression system). The HVAC&R system may place the working fluid in a heat exchange relationship with a conditioning fluid (e.g., water) to heat and/or cool the conditioning fluid and may then deliver the conditioning fluid to various destinations to be utilized. For example, the HVAC&R system may include a heat pump system (e.g., heat pump vapor compression system) that includes one or more heat exchangers, where each heat exchanger is configured to receive a respective flow of working fluid and a respective flow additional fluid and to place the working fluid in the heat exchange relationship with the additional fluid. [0004] In general, energy transferred by a first heat exchanger of the heat pump system (e g., heat transferred from the working fluid to a first additional fluid) may be approximately equal to a combination of energy transferred by a second heat exchanger of the heat pump system (e.g., heat transferred from a second additional fluid to the working fluid) and energy consumed by a compressor of the heat pump system. However, heat pump systems may be utilized in applications having variable cooling loads and/or heating loads. Thus, existing heat pump systems may operate inefficiently in various operating conditions. Accordingly, improved heat pump systems that more efficiently and/or effectively satisfy varying heating and/or cooling loads are desired.
