Novel experimental-based study aims to determine the extent to which performance parameters of water heater system are altered when the heat pump is integrated and to clarify the optimum values of system variables by means of an optimization procedure using reliable experimental data. Considering compressor speed, air flow over evaporator as variables, experiments for both conventional electrical resistance and proposed heat pump integrated water heater for household appliances were conducted. Energy consumption, noise level and operating time were recorded. Experimental results reveal that energy consumption for heating 4 L water up to 50 °C is decreased by up to 26% in heat pump integrated water heater system, whereas noise level and operating time is increased by minimum 0.9 dBA and 65 min, respectively. Time-averaged COP value ranges in between 3.0 and 3.54 in the experiments, but for more realistic ambient temperature cases it may increase up to 7.5. Multi Objective Particle Swarm Optimization algorithm was performed for system components using curve fitted experimental data for the optimum values of system variables by considering energy consumption, noise level and operating time as objectives. Results lead to 17% decrease in energy consumption, 3.9 dBA increase in noise level and 82 min longer operating time.

Experimentation and optimization of a heat pump integrated dishwasher Kütük, Erkan; Bayer, Özgür; Department of Mechanical Engineering (2019) This study aims to develop the optimization of heat pump system working parameters for minimum energy consumption, operating time and noise level for a novel dishwasher. In an integrated heat pump system, compressor speed (N) and air flow rate (V̇) over the evaporator are selected as variables that affects energy consumption (E), acoustic level (A) and operating time (t). Due to the international energy regulations for household appliances, energy efficiency is highly important and for user comfort, operati...
Experimental investigation of a natural zeolite-water adsorption cooling unit Solmus, Ismail; KAFTANOĞLU, BİLGİN; Yamali, Cemil; Baker, Derek Keıth (Elsevier BV, 2011-11-01) In this study, a thermally driven adsorption cooling unit using natural zeolite-water as the adsorbent-refrigerant pair has been built and its performance investigated experimentally at various evaporator temperatures. The primary components of the cooling unit are a shell and tube adsorbent bed, an evaporator, a condenser, heating and cooling baths, measurement instruments and supplementary system components. The adsorbent bed is considered to enhance the bed's heat and mass transfer characteristics; the b...
Numerical Analysis of Phase Change Material Characteristics Used in a Thermal Energy Storage Device Bonyadi, Nima; Somek, Suleyman Kazim; Ozalevli, Cemil Cihan; Baker, Derek Keıth; Tarı, İlker (2018-01-01) In this study, a numerical analysis is performed to investigate the freezing process of phase change materials (PCM) in a predesigned thermal energy storage (TES) device. This TES device is integrated with a milk storage cooling cycle operating under predefined practical conditions. Using this cooling unit, 100 litres of milk is kept cool at 4 degrees C for 48 hours before it is collected. A 2-D model of the TES device is developed in COMSOL Multiphysics to analyze the phase change performance of water-base...
EXPERIMENTAL INVESTIGATION AND PERFORMANCE ANALYSIS OF GASKETED-PLATE HEAT EXCHANGERS Akturk, Fatih; Sezer Uzol, Nilay; Aradag, Selin; Kakac, Sadik (2015-01-01) In this study, the thermal and hydrodynamic performance analyses of sa elected gasketed-plate heat exchanger with different number of plates are performed experimentally. A gasketed-plate heat exchanger (GPHE) test set-up is designed and constructed to perform experimental measurements for thermal and hydrodynamic performance analyses of plate heat exchangers. The experiments are performed for an industrial chevron-type plate heat exchanger under different flow conditions for a wide range of Reynolds number...
Numerical analysis of an organic Rankine cycle under steady and variable heat input Bamgbopa, Musbaudeen O.; Uzgoren, Eray (Elsevier BV, 2013-07-01) This paper develops a strategy to maintain steady operation of an organic Rankine cycle (ORC) by adjusting evaporator flow rates in relation to the available thermal energy. ORC unit under investigation uses R245fa as the working fluid, for which a regression based approach was implemented to evaluate its state properties. Steady and transient models for unit's subcomponents (pump, evaporator, expander and condenser) were developed. Heat source is considered as solar heated water between 80 degrees C and 95...
