Abstract
This paper is part 1 of the investigation on the exergetic and exergoeconomic parameters of an existing system with an air-to-water heat pump unit as a heat source. Part 1 presents the used experimental setup. The main aim of the conducted experimental tests is to develop a model of produced heat transfer rate and energetic COP at different ambient conditions. The obtained data is used in Part 2 of the study where the exergetic and exergoeconomic assessment is carried out. The performance of the considered system is evaluated using Seasonal Exergy Efficiency. Moreover, Part 2 of the study has presented the formulation of the cost of the product, and cost allocation within the heat pump unit based on exergy.
Highlights
There is a wide discussion about the performance parameters of air-to-water heat pumps (AWHP)
In many studies is conducted experimental and theoretical research on the factors that affected the coefficient of performance (COP) of an aerothermal heat pump and consumed electrical energy
Zhao et al [1] conduct the experimental study of an aerothermal heat pump and they establish the influence of the water temperature in the tank on the observed COP of the heat pump when the external air temperature remains almost constant
Summary
There is a wide discussion about the performance parameters of air-to-water heat pumps (AWHP). The experiment is conducted to validate the developed model of the system’s performance Another part of studies in reference literature deals with experimental and theoretical research of novel airto-water heat pump systems [4,5,6]. In this regard, the current paper suggests the simplified method for experimental research of an existing AWHP system, considering the system as a black-box with defined inputs and outputs. The obtained data is used in Part 2 of the study where the exergetinc and exergoeconomic assessment is carried out
