Abstract
Air gets heated while passing through the desiccant wheel in a hybrid air conditioning system and needs to be cooled before passing to cooling coil. This hot air can be an effective heat source for the air source heat pump to heat the water. The present work includes experimental investigation of the dehumidifier integrated hybrid R-407C air source water heat pump under different air temperature to achieve hot water. The results exhibit that heating capacity increases by 15% by increasing the air-source temperature from 30 to 45 °C. End loop COP of the system is reduced by 25%.
