Abstract

Owing to CO₂ is an environmentally friendly natural refrigerant, recently, its application on heat pump has been great interested worldwide. Among those applications, CO₂ heat pump water heater, one of the most interesting topics, has been aggressively studied due to its outstanding heating performance. The water heating flow rate is a significant factor to affect the system COP in a heat pump water heating loop connected to a storage tank, and there is not many experimental studies focused on it. Therefore, in this paper, an optimal heating COP under various water heating flow rate of a CO₂ heat pump system was studied. The results show that water flow rate is a significant factor to the COP, and the optimal COP can be found for a series of various water flow rate.
