Résumé

Even though eco-friendly R744 cooling and heating technology is mature and has now become a benchmark in the European and North American markets, it is, however, challenging to implement the same with a similar strategy in developing countries such as India. The wider market share of traditional man-made (synthetic) refrigerants is another constraint. The study's motivation is to gain the global HVAC&R sector's attention and to spotlight the major benefits of executing an ejector-based R744 heat pump/chiller unit focusing on the economic and environmental perspectives. Thus, a robust R744 heat pump/chiller design is being implemented in a Hotel in Goa, India to fulfill overall heating and cooling demands. To address the peak load strain and instability, four heat pump/chillers also known as modules are operated in parallel with an integration of a common hot thermal storage validated. To execute the same, a unique approach is being adopted to build an in-house heat pump/chiller unit to deal with all practical, geographical challenges and issues related to the components to withstand the tropical conditions around the year. Moreover, an innovative control modulation strategy is intended to achieve a constant demand for hot and cold water at 70⁰C and 7⁰C, respectively, with optimum heat pump/chiller control. Dissemination of the state-of-the-implementation and real-time field results would be interesting to share with the scientific community.
