Performance of a thermoelectric heat pump with recirculation and regenerative heat recovery

Benzhi Hou et al.

Summary: The performance of thermoelectric heat pumps is enhanced by air recirculation and regenerative energy recovery. Experimental results show that the COP of the air recirculation TEHP is as high as about 3.7, and the COP with recirculation is 51-73% higher than without recirculation. The combination of regenerative heat recovery and air recirculation further improves the energy efficiency of the heat exchanger test system.

Optimal combination of an air-to-air thermoelectric heat pump with a heat recovery system to HVAC a passive house dwelling

A. Martinez et al.

Summary: The main objective of this research is to propose a HVAC system for a passive house dwelling using a thermoelectric air-to-air heat pump and a heat recovery unit. The computational investigation shows that integrating the heat recovery unit significantly improves the performance of the heat pump and reduces the number of required modules. Another analysis evaluates the seasonal heating performance of the system in different climates and finds that the optimal number of thermoelectric modules is close to 15 in all cases. The study also suggests that improving the heat exchangers between the thermoelectric modules and the cooling air stream is more effective in increasing the cooling capacity than increasing the number of modules.

Recent developments in ohmic technology for clean label fruit and vegetable processing: An overview

Ume Roobab et al.

Summary: Consumer perceptions and preferences play a crucial role in determining the commercial future of food and its ingredients. Health-conscious and educated consumers are increasingly interested in natural, minimally processed foods. Ohmic heating (OH) is an emerging technology that allows for uniform and quick heat generation in food, with minimal damage to heat-labile nutrients. This study provides a comprehensive overview of OH applications in inactivating degrading enzymes and preserving the natural properties of food, as well as its combination with nonthermal techniques. OH has high potential and wide scope in the food and vegetable sector, with applications in dehydration, evaporation, blanching, and extraction.

Realizing the curing of polymer composite materials by using electrical resistance heating: A review

Chengming Yue et al.

Summary: This review highlights the important application value of electrical resistance heating curing (ERHC) method in the preparation of polymer-matrix composites (PMCs). The heating mechanism of ERHC is briefly introduced, and the ERHC method is classified into three types based on different forms of electric heating elements: fibers, fillers, and membrane sheets. The preparation methods for these three types of electric heating elements are summarized. The advantages of ERHC are obtained through analysis and comparison.

Net zero in the heating sector: Technological options and environmental sustainability from now to 2050

Peter C. Slorach et al.

Summary: This paper assesses the environmental sustainability of a range of heating technologies and scenarios on a life cycle basis, identifying heat pumps as one of the most environmentally friendly options but highlighting the high energy demand and impacts of hydrogen production through electrolysis. Gas boilers, despite higher carbon emissions, remain the lowest impact option in certain categories due to impacts related to electricity generation being avoided.
