“…En la industria automóvil existen numerosas investigaciones relacionadas con el uso de bombas de calor para calefacción. Las referencias [1][2][3] analizan el uso de bombas de calor que utilizan una fuente de calor dual: aire ambiente y calor residual del sistema. Suzuki e Ishii [4] realizan un estudio similar al desarrollado en este estudio, obteniendo un COP de 2,3 y un flujo de calor de 2,3 kW para una bomba de calor operando a -10 ºC.…”

RESUMENEl sistema de aire acondicionado y de calefacción en los automóviles se utiliza principalmente por motivos de seguridad para garantizar que el conductor esté concentrado y con buena visibilidad durante la conducción. Para la calefacción, en los vehículos convencionales, se cuenta con una energía térmica considerable y a una excelente temperatura, esto debido al calor disipado por el motor a combustión. Los vehículos eléctricos no cuentan con esta fuente de calor, por lo que se debe suplir por algún sistema auxiliar como resistencias eléctricas o una bomba de calor. En el estudio que se desarrolla en esta investigación se propone utilizar una bomba de calor para la calefacción del automóvil. El objetivo que se plantea en este estudio es validar experimentalmente un principio de calefacción para automóviles eléctricos basado en una de bomba de calor reversible y desarrollar un modelo de simulación para explorar su desempeño a diferentes condiciones de operación. La bomba de calor se logró ensayar a temperaturas de hasta -10 ºC, obteniéndose COP superiores a 2,0 en todo el rango experimental. La modelación de la bomba de calor permite establecer que esta es capaz de funcionar en condiciones aceptables de hasta -10 ºC, con un COP del orden de 1,48 y un calor transferido por el radiador de 4,1 kW, con un flujo de aire impulsado a la cabina a 45 ºC, lo que permite mantenerla a temperaturas por sobre los 20 ºC.Palabras clave: Bomba de calor, reversible, vehículo eléctrico, caracterización experimental, modelado.

“…Heat pumps utilise the available waste heat and extract some thermal energy from ambient. Leighton et al and Ahn et al have shown the prospective benefits, providing ambient conditions are suitable, of using heat pumps in electric vehicles [28,29]. Leighton showed that a system that could utilise waste heat from the inverter and electric motor could provide a 2.6% improvement in range at −12 • C, taking the low temperature range from 46.2% to 48.8% of the nominal range.…”

Abstract:Previous research has focused on the use of heat pumps in electric vehicles, with the focus on recuperating heat from, normally, ambient and one thermal source on the vehicle. Here 5 potential thermal sources on a vehicle have been identified and thorough testing on the benefit of each source has been performed. The results presented suggest the motor, a thermal storage device, and cabin exhaust extraction should be used >80% of the time according to the scenarios tested, while battery heating and transmission heat extraction should be used subject to conditions on the ambient temperature and drive cycle.

“…Promme [82] proposed a reversible heat pump system with an additional heat source which could utilize the waste heat of the battery, driven electric motor and electronic control unit. Ahn and Woo [83,84] investigated a dual source heat pump (using both air and waste heat) in EVs, which is shown in Figure 11. Figure 10.…”

Electric vehicles have become increasingly popular in recent years due to our limited natural resources. As a result, interest in climate control systems for electric vehicles is rising rapidly. According to a variety of research sources, the heat pump air conditioning system seems to be a potential climate control system for electric vehicles. In this paper, an extensive literature review has been performed on the progress in heat pump air conditioning systems for electric vehicles. First, a review of applications of alternative environmentally friendly refrigerants in electric vehicles is introduced. This is followed by a review of other advanced technologies, such as the inverter technology, innovative components and the system structure of the heat pump air conditioning system for electric vehicles. Lastly, recent developments in multiple source heat pump systems are presented. The use of these advanced technologies can provide not only sufficient refrigerating capacity for the electric vehicle, but also higher climate control system efficiency. We believe that ideal practical air conditioning for electric vehicles can be attained in the near future as the mentioned technical problems are gradually resolved.
