Summary

The main objective of this project is to explore the capacities of a 60 kW air-water heat pump using CO2 (or R-744) as refrigerant for the production of hot water at the Le Locle hospital (canton of Neuchâtel, Switzerland). The goal is to produce hot water with a temperature of 60 to 80°C from cold water at a temperature of 10°C. The project will permit real-time measurement of the COP of the heat pump under differing conditions of use (e.g. changes in the temperature of the cold water), as well as its verification over an extended period of time in order to evaluate its performance under changing seasonal conditions.
