“…In order to reduce energy consumption in buildings for heating and cooling, a solarassisted hybrid power gas heat pump is proposed [68]. The analysis shows that, according to various photovoltaic factors, the use of PV arrays leads to a significant improvement in energy consumption but at the same time causes a significant impact on the environment.…”

In this paper the most promising developments of technology for gas engine-driven heat pumps for the last 15 years are presented. The purpose is to present the latest research studies and changes in this type of device, as well as to help readers to search for publications containing relevant aspects of gas engine heat pumps. Gas engine-driven heat pumps are devices for parallel heating and cooling production based on compressor heat pump technology. However, unlike heat pumps with compressors powered by electric motors, gas engine-driven heat pumps are driven by gas internal combustion engines. The reviewed solutions are an interesting alternative to traditional heating systems, characterized by the higher than 1.0 Performance Energy Ratio which expresses the degree of conversion of the energy contained in the fuel supplied to the device into energy transported to the utility needs. Presented in this review, papers show different solutions for conversion of the energy contained in the fuel into mechanical and thermal energy, and mechanical energy through the shaft system is used to drive the compressor of the heat pump. The presented study shows that, due to the complexity of the system and the wide range of applications, the technology has been subjected to detailed analyses and optimizations during the last 30 years in order to increase the efficiency of devices.

“…Building energy consumption accounts for around 40% of the total energy consumption, and 45% of the building energy is consumed by the air-conditioning systems [1]. As a passive cooling technology, radiative cooling can mitigate heat from the objects on earth to outer space through atmospheric windows, which can not only reduce fossil energy consumption, but can also decrease the effects of global warming [2].…”

Passive radiative cooling technology has attracted much attention for its ability to obtain “free” cooling by heat exchange between objects on earth and outer space through atmosphere window. However, most of the existing radiative cooling materials are prepared in the form of thin films, which limits the application of radiative cooling in building since the films are lacking in scalability and the various building shapes. In this paper, we prepared a radiative cooling paint (RCP) with acrylic resin as the substrate, and mixed with ploymethylpentene (TPX), and silicon dioxide (SiO2). The emissivity of 0.87 and reflectively of 0.92 is achieved in atmosphere window (i.e., 8-13 μm) and solar spectrum (i.e., 0.2-2.5 μm), respectively. To further indicate the cooling potential of the proposed RCP for its building applications, a two-floor single-family house is modeled using EnergyPlus. The cooling energy saving potential of the prepared RCP for applying on different surfaces of the building envelope is analyzed, and the influence factors for the application of RCP is discussed in detail. The results show that a significantly cooling energy saving can be achieved for the buildings painted with the proposed RCP on all surfaces (i.e., roofs and walls) in which the annual cooling energy consumption can be decreased by 15.8-31.2% comparing to the building with typical roofs and walls located at all five climate zones in China.
