Understanding CO2 Heat Pump Technology

At its core, a heat pump is a device that transfers heat from one place to another using a refrigerant as a working fluid. Traditional heat pumps often utilize synthetic refrigerants, many of which have a high Global Warming Potential (GWP), contributing significantly to climate change. CO2 (R744), on the other hand, is a natural refrigerant with an exceptionally low GWP of 1. This inherent environmental advantage, coupled with its excellent thermodynamic properties, makes CO2 an ideal refrigerant for next-generation heat pumps.

CO2 heat pumps operate on the same principle as conventional heat pumps but leverage the unique characteristics of carbon dioxide. They can efficiently extract heat from low-temperature sources like the air, ground, or water and elevate it to higher temperatures for heating purposes. Conversely, the cycle can be reversed for cooling. Notably, CO2 heat pumps excel at producing high water temperatures, making them particularly well-suited for applications like domestic hot water, district heating, and industrial processes.

Driving Forces Behind the Adoption of CO2 Heat Pumps in South Korea
