The integrated application can effectively improve heat pump COP, operational stability of heat pumps and the comfort level of users. This integration is promising in the field of building energy conservation.
This study analyzes the operational performance of the system primarily driven by off-peak electricity and examines the influences of different thermal storage times and capacities on the economy of the system. Experiments were conducted in the high-altitude region of Qinghai.
When solar energy is sufficient, part of the heat is collected by a solar collector and used as a heat source when the heat pump is operating, and the other part is stored in the phase-change heat-storage tank, which is used when there is no solar energy.
Ever wondered how your heat pump could work smarter, not harder? Enter phase change energy storage – the tech that''s making heating systems remember like elephants and flex like gymnasts.
Therefore, we propose a novel cascaded heat pump with integrated phase change thermal storage. The dual circuit configuration decouples meeting the building thermal load from thermally discharging or charging TES.
Abstract This paper proposed a dynamic model-based configuration and operation optimization method for an renewable integrated energy system (IES) containing heat pump coupled with phase change material and water (PCM) energy storages, considering thermal inertia and thermal comfort elasticity.
Integrating heat pumps with high-efficiency latent heat thermal energy storage systems with phase change materials (PCMs) can increase the heat temperature and heat quantity, enabling flexible heat regulation and cascade utilization.
Heat pumps (HPs) are promising solutions for sustainable building heating owing to their high efficiency and low carbon footprint. However, their performance is often limited by challenges such as defrosting, peak electricity demand, and reliance on intermittent renewable sources. Integrating phase change material (PCM)-based thermal energy storage (TES) with HP systems has
