Air energy heating plus solar power generation

Can a novel solar-air source heat pump system save energy?

The novel system has evident advantages in economy and energy savings. In order to solve the problem that the traditional heat pump system in the cold area of North China cannot supply heat efficiently and stably, a novel solar-air source heat pump system is proposed to meet the needs of building energy consumption.

How much energy does a PV/T system save?

In addition, the annual power generation of the PV/T modules was about 6100 kWh, and the average power generation efficiency was 14.5%. Compared with thermal power generation, the PV/T modules of the system can save about 1.85 t of standard coal (calculated by 303.7 g/kWh coal consumption for thermal power generation ).

What is solar photovoltaic power generation?

Solar photovoltaic power generation meets part of the power demand of the system, which can save about 1.85 t of standard coal compared with thermal power generation. Compared with a conventional air source heat pump system, the novel system has better economy and a dynamic investment payback period of 3.86 years.

How does a solar-air source heat pump work?

A novel solar-air source heat pump system utilizes the latent heat of water. The TRNSYS simulation model is established with experimental data. The operation of the system and the size of each component are optimized. An ice tank can provide heat for the heat pump for two days under low irradiation.

What is a novel air source heat pump system?

Compared with a conventional air source heat pump system, the novel system has better economy and a dynamic investment payback period of 3.86 years. The proposed system presents a way to meet building energy supply that is worthy of popularization and application in cold areas. 1. Introduction

What is the difference between single air heat source and dual heat source?

Further experiments show that compared with the single air heat source mode, the heating capacity of the dual heat source mode increases by 62%, and the coefficient of performance (COP) increases by 59% . Wu et al. developed a solar regenerator composed of flat heat pipes filled with phase change materials for the SAHP system.
