Proposal and assessment of a new solar space heating system by integrating an absorption-compression heat pump

Applied Energy, 2021
In cold regions, solar space heating is a clean and promising method that can be used to reduce the consumption of fossil fuels and electricity; however, the heat supply cost is extremely high because of the high investment, low energy efficiency, and ...

A novel spatial–temporal space heating and hot water demand method for expansion analysis of district heating systems

Energy Conversion and Management, 2021
The fourth generation of district heating will play a significant role in the decarbonization of energy systems. In general, only space heating demand is considered when assessing the district heating potential, excluding hot water.

New scenario of CO2 heat pump for space heating: Automatic mode switch between modified transcritical and cascade cycle in one system

Applied Thermal Engineering, 2021
Hot water production and space heating consume huge amounts of energy. CO2 heat pump has been proven more efficient in hot water production, but less efficient in space heating. In the paper, we proposed a new scenario of CO2 heat pump for space heating.

Thermal analysis of a water source heat pump for space heating using an outdoor pool as a heat source

, 2021
Water bodies are identified as potential heat sources (heat sink) for space heating (cooling) purposes. Thus, the nearby buildings can benefit from these sources by employing heat pump systems.

The environmental consequences of electrifying space heating.

Environmental Science and Technology, 2020
Decarbonization may require the efficient electrification of applications, like natural gas furnaces for space heating, that currently involve burning fossil fuels. The environmental consequences of such a fuel switch depend on location and time. Here we

Combined Space-Heating/Water-Heating System Performance

Advanced Energy Systems, 2001
Abstract With increasing fuel prices, various energy-saving techniques have been considered for residential appliances. Space heating accounts for the largest energy use in residential applications. One method proposed by manufacturers to keep operating cost low is to combine residential water-heating and space-heating functions into a ...
