The presentation by Troy Davis, Mayekawa USA MYCOM, discusses the introduction of Mayekawa's ECO Cute water source hot water heat pump at Torres De Alba Hotel in Panama City. The hotel owner recently installed the first ever integrated CO₂ refrigerant water source heat pump heating and cooling system implemented in a hotel in Central America. By combining the hot water heating system with the chilled water cooling system using the Mayekawa water source heat pump unit, a higher COP is realised versus individual systems. This integrated system has been in operation since the summer of 2013 and the calculated payback period for the new heat pump system is less than 3 years.
