Thermodynamic performance evaluation of a heat pump system with textile based solar air heater for heating process

Research on the operation strategies of the solar assisted heat pump with triangular solar air collector

“…While for the TSAHP system under the optimal working mode, the TSAC can operate from 8:00 to 18:00, including nine hours of preheating mode and three hours of series mode, and the average COP is increased by 6.2%, and the power consumption is reduced by 0.3 kWh. Even on a cloudy day, the maximum COP of TSAHP is 5.18 under the optimal working mode, which is higher than 5.11 in the Ref [22].…”

“…Safijahanshahi and Salmanzadeh [21] applied transpired SAC to the ASAHP system, and the results show that a 1 m 2 collector could assist a 1 kW ASHP and the transpired SAC significantly reduced the electricity consumption of ASHP. Ural et al [22] compared the ASAHP with the novel transpired SAC and the traditional flat-plate SAC.…”

Visualization Analysis on the Current Status and Development Trend of Geothermal Research: Insights Into the Database of Web of Science

“…"Thermal performance," "exergoeconomic analysis," and "hydraulic fracturing" are the latest burst term (Table 3). For instance, the following aspects are attracting a large number of researchers to study: 1) In the development of shallow geothermal energy and hydrothermal geothermal resources, how to improve the thermodynamic performance of the ground source heat pump (Hou et al, 2020;Ozturk et al, 2020;Pishkariahmadabad et al, 2021;Ural et al, 2021). 2) How to prolong the service life of deep borehole heat exchangers, using the exergoeconomic method and thermodynamic modeling; in order to optimize the benefits of geothermal power plants (Fiaschi et al, 2014;Pambudi et al, 2018;Martínez et al, 2020;Yan et al, 2021).…”

Energy, exergy, economic and environmental assessment of the triangular solar collector assisted heat pump

“…Two-dimensional exergy diagram was used to illustrate the dynamic exergy performance of both systems, and the SAHP is considered to have the best exergy efficiency. Ural et al (2021a; tested the ASHP with fabric solar air collector, and evaluated its thermodynamic performance and economy. The results showed that the electrical consumption of the novel SAHP system decreased by 8%, total exergy efficiency values increased by 3.1%…”
