Abstract: Shifting the air conditioning (AC) cycle from conventional to efficiently novel cycle is one of the effective ways to save energy and reach sustainability. In this experimental investigation, an effort had been made in design, fabrication, and evaluated the thermal performance of air conditioning coupled with heat recovery to produce free hot water for residential. It is also investigated the effect of the number of twisted tapes insert inside the heat recovery unit. The experiment was conducted in a 4 x 4 m room with 1 pk compressor power. Heat recovery was used to increase water temperature after coming in contact with hot refrigerant from the discharge of the compressor. This hot water was delivered to the thermal storage tank. The result indicated an increase in temperature and energy of the heat recovery tank by around 0.2%, 6.0%, 6.8%, 17.3% using one, two, three, four twisted tapes.
