Abstract: The heat pump technology is applied to the products of the water dispenser, and the heat and cold capacity of the heat exchanger are used to make water at a specific temperature, so as to improve the energy utilization rate and achieve the effect of energy saving and emission reduction. In this paper, a heat pump type water dispenser with heat production of 1026 W and COP of 2.02 is designed by combining water tank and heat exchanger, by which heating water temperature can reach 72 ℃. The economic benefits of the heat pump type water dispenser are analyzed, and the improvement scheme of the heat pump type water dispenser is provided, which provides theoretical and data support for replacing the electronic ice bladder and realizing large energy saving.

Key words: Heat pump, Water dispenser, Energy conservation, Water cooling
