A high-temperature heat pump for compressed heat energy storage applications: Design, modeling, and performance

Hassan, Abdelrahman; Corberán, José M.; Ramirez, Miguel; Trebilcock-Kelly, Felipe; Payá-Herrero, Jorge (Elsevier, 2022-11)

[EN] The current paper presents the design and performance of a high-temperature heat pump (HTHP) integrated in an innovative, sensible, and latent heat storage system. The HTHP has been designed to work between a heat ...
Aprovechamiento del calor residual a baja temperatura mediante bombas de calor para la producción de agua caliente

Hervás Blasco, Estefanía (Universitat Politècnica de València, 2020-02-24)

[ES] Un porcentaje significativo de la energía se destina a la producción de Agua Caliente Sanitaria (ACS) en el sector comercial y residencial. Además, la mayor parte de la energía que contiene el agua se desperdicia en ...
Evaluation of different heat pump systems for sanitary hot water production using natural refrigerants

Pitarch, Miguel; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Elsevier, 2017)

[EN] Heat pumps that work with a high degree of subcooling in subcritical systems have shown a significant margin of improvement when working with sanitary hot water applications. Recently, two different approaches ...
Evaluation of optimal subcooling in subcritical heat pump systems

Pitarch, Miquel; Hervas-Blasco, Estefanía; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Elsevier, 2017)

[EN] The performance of a transcritical cycle is highly dependent on the rejection pressure. The optimal rejection pressure depends mainly on the inlet and outlet temperatures at the heat sink (secondary fluid). For the ...
Exergy analysis on a heat pump working between a heat sink and a heat source of finite heat capacity rate

Pitarch, Miguel; Hervás-Blasco, Estefanía; Navarro-Peris, Emilio; Corberán, José M. (Elsevier, 2019-03)

[EN] The optimum performance of a pure subcritical refrigeration cycle depends significantly on the temperature lift of the heat source and sink. Therefore, the maximization of the system efficiency has to be linked to ...
Experimental study of a heat pump with high subcooling in the condenser for sanitary hot water production

Pitarch, Miguel; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Taylor & Francis, 2018)

[EN] The use of heat pumps in order to produce sanitary hot water have been demonstrated as a very efficient alternative to traditional boilers. Nevertheless, the high water temperature lift (usually from 10 degrees C to ...
Experimental study of a subcritical heat pump booster for sanitary hot water production using a subcooler in order to enhance the efficiency of the system with a natural refrigerant (R290)

Pitarch, M.; Navarro-Peris, Emilio; Gonzálvez-Maciá, José; Corberán, José M. (Elsevier, 2017)

[EN] This paper presents the experimental results obtained from a new heat pump prototype for sanitary hot water production, in the application of heat recovery from water sources like sewage water or condensation loops ...
High capacity heat pump development for sanitary hot water production

Pitarch i Mocholí, Miquel (Universitat Politècnica de València, 2017-05-29)

Heat pumps have been identified as an efficient alternative to traditional boilers for the production of sanitary hot water (SHW). The high water temperature lift (usually from 10ºC to 60ºC) involved in this application ...
Improved water to water heat pump design for low-temperature waste heat recovery based on subcooling control

Hervas-Blasco, Estefania; Navarro-Peris, Emilio; Barceló Ruescas, Francisco; Corberán, José M. (Elsevier, 2019-10)

[EN] Traditional heat pumps designs have been optimized for heating applications based on small secondary temperature lifts (around 5K); however, in applications with other characteristic temperature lifts, different design ...
Visualization of refrigerant flow at the capillary tube inlet of a high-efficiency household refrigerator

Martínez-Ballester, Santiago; Bardoulet, Laetitia; Pisano, Alessandro; Corberán, José M. (Elsevier, 2017)

[EN] The subcooled condition at the condenser outlet ensures complete condensation, which is necessary in vapor compression systems to increase the cooling capacity and ensure the liquid conditions at the expansion device ...
