From the perspective of mitigating global warming, refrigerants currently in use for refrigeration and air conditioning equipment need to be replaced by those with a lower global warming potential (GWP). However, most condensing units, which are used to refrigerate cold storage warehouses or showcases in supermarkets, still use fluorocarbon refrigerants with a large GWP such as R404A (GWP: 3920) and R410A (2090). To address this issue, Mitsubishi Heavy Industries Thermal Systems, Ltd. (MTH) released 10-horsepower (HP) and 20-HP commercial condensing units of the "HCCV series" using natural refrigerant CO2 (GWP: 1), and these units have earned a good reputation. However, when it comes to the application of these 10-HP and 20-HP models to large cold storage warehouses or supermarkets, Some installers and customers consider that the multiple unit installation entails complicated refrigerant piping systems and increased construction costs, which are said to be obstacles to introduction. Therefore, we have newly-developed a 40-HP condensing unit as a larger capacity model of the "HCCV series", thereby achieving simplified refrigerant piping, space saving and reduced weight. This report presents the product characteristics and specifications.
