Performance analysis of a R407C liquid-to-water heat pump: Effect of a liquid–vapor heat exchanger and domestic hot water production

Abstract

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Highlights  An experimental analysis of a liquid-to-water heat pump with R407C is presented  Experimental results for space heating with domestic hot water production (DHW)  The effect of using or not a liquid-vapor heat exchanger (LVHEx) is evaluated  DHW and LVHEx affects refrigerant charge distribution inside the heat pump  DHW production and LVHEx affects the heat pump performance

Utilization of Solar Energy for Water Heating Application to Improve Building Energy Efficiency: An Experimental Study

“…In this system condenser is used as a heat exchanger. There are numerous types of liquid-to-liquid heat exchangers use in literature [29,30]. But in Indian solar water heating system, only concentric tube and within tank heat exchangers are used.…”
