Abstract
Motivated by the rapid spread of the novel pandemic disease (COVID-19) that swept the most countries in the world, a new radiation heating system consists of wall radiator panel system connected to a reversible geothermal heat pump (GHP) coupled with horizontal ground heat exchanger (HGHX) was proposed as fast and permanent solution to the risks of the dispersion of airborne infectious diseases in air-conditioned enclosed spaces. An experimental system was installed and tested in the laboratory of thermal process of Research and Technology Center of Energy (CRTEn), Tunisia, in order to achieve the two main goals of this work: developing a new radiation heating system with quick and inexpensive implementation while ensuring high efficiency and environment-friendly performance for the entire system. The results obtained show that it is feasible to use the novel RPHs as heat rejecter of the horizontal ground source heat pump system (HGSHPs) for heating buildings with limited surface land areas epically those located in the Mediterranean regions such as Tunisia, the average performance coefficients of the geothermal heat pump COPhp and the overall system COPsys are found to be 6.3 and 3, respectively. The thermal comfort analysis indicates that there is only a small vertical temperature fluctuation in the test room that would not produce any negative effect on thermal comfort.
Highlights
In December 2019, an outbreak of respiratory illness was notified in China, it was later proven that the new disease which first appeared in Wuhan, a city in Hubei Province, was caused by a novel Coronavirus, officially called Coronavirus Disease 2019 (COVID-19) [1]
Since the public places and certain types of residential rooms are characterized by intermittent random usage, the directly activated building system (DABs) that allow fast conditioning are commonly the most appropriate option, and since we focus in this study on buildings with limited land surface areas such as rooms used for critical care and residential rooms, the radiators panel heating system (RPHs) which usually occupy small spaces is more suitable by increasing the heat exchange surfaces through the pipe coils [13]
The thermal behavior of a novel wall radiator panel heating system connected with horizontal ground source heat pump was examined experimentally under the climatic conditions of the Mediterranean region
Summary
In December 2019, an outbreak of respiratory illness was notified in China, it was later proven that the new disease which first appeared in Wuhan, a city in Hubei Province, was caused by a novel Coronavirus, officially called Coronavirus Disease 2019 (COVID-19) [1]. COVID-19 has rapidly spread in China and to multiple countries to reaching more than 21 million confirmed cases in less than 9 months [2]. To reduce the potential airborne transmission of this pandemic disease and any other airborne micro droplets containing viruses in enclosed spaces, especially public buildings which are used randomly
