Air energy heat pump and phase change energy storage heating

What are phase-change energy storage devices based on a Pvt-air source heat pump?

In order to solve these problems, two kinds of phase-change energy storage devices are combined on the basis of a PVT-air source heat pump system, namely, a low-temperature phase-change energy storage (ice tank) and a medium-temperature phase-change energy storage (phase-change thermal storage device (PCTSD)).

Can phase change thermal storage technology be used in air-source heat pump?

The application of phase change thermal storage technology in three fields of air-source heat pump was summarized. The problems still existing in three applications were presented. The future research directions of latent thermal energy storage air-source heat pump are pointed out.

Can a dual-source heat pump use phase-change energy storage?

Conclusions In this study, a novel dual-source heat pump system was proposed, which used phase-change energy storage to realize the cascade utilization of heat and the complementary advantages of solar energy and air energy.

What is a phase change thermal storage unit?

By combining a phase change thermal storage unit with the evaporative side of the air-source heat pump, the thermal storage unit is used to defrost the outdoor unit and delay the reduction of heat production of the air source heat pump due to the low-temperature environment by thermal storage.

How latent thermal energy storage air-source heat pump can improve performance?

The future research directions of latent thermal energy storage air-source heat pump are pointed out. Combining phase change thermal storage technology with air-source heat pumps can improve the performance coefficient and stability of air-source heat pumps operating in low-temperature environment.

How ASHP compared to dual-source heat pump system?

The increased initial investment cost of the dual-source heat pump system compared with the ASHP system was mainly the PVT module and energy storage system, which is 49,000 CNY. The economic benefits of the system were mainly reflected in the reduction of energy consumption and the utilization of power generation.
