This session will discuss the advantages and challenges of using CO2 Heat Pumps for decarbonizing and efficiently electrifying commercial Domestic Hot Water systems. The session will outline and discuss the Mitsubishi Electric Heat2O DHW solution along with other CO2 DHW systems and their applications. The functionality, operation, scalability, and relevant design challenges related to these types of solutions will be explained. This session will discuss the use and benefit of CO2 as a refrigerant and its impact on environmentally sustainable buildings. Participants will understand the energy benefits of low input, off-peak storage to reduce peak demand for the electric grid.

Learning Objectives
Explain the theory, application and available tools associated with CO2 based all electric commercial DHW systems.
Assess the mechanical requirements associated with the technology and how all-electric DHW layouts significantly differ from fossil fuel systems.
Explore how using all-electric solutions is beneficial to the end-user and the environment while still allowing the electric infrastructure to grow.
Identify the paradigm shifts associated with moving from fossil fuel to all electric solutions and the role of CO2 refrigerant domestic hot water systems in meeting this challenge.
