چکیده انگلیسی

A novel ground source heat pump heating system with air seasonal heat storage (GSHPASHS) is described. This is followed by reporting the development of a simplified mathematical model for the system. The operational performances of the GSHPASHS system applied in a house of 120m2 building area in Harbin (N45.75°, E126.77°) have been investigated by simulation. The results show that the system can meet the heating space needs of the building. The air seasonal thermal storage can raise the soil temperature around the ground heat exchanger to a higher level, which is favorable for increasing the coefficient of performance of the heat pump.

مقدمه انگلیسی

In severe cold area, if ground source heat pump (GSHP) system is used for heating space, the soil temperature will decrease gradually around the ground heat exchanger (GHE) due to the much large heating load in winter, which can lead to the drop of the heat pump performance year by year. Therefore,the GSHP heating system must be integrated with other heat source to operate in severe cold area. The solar energy as the heat source of the seasonal heat storage has attracted much attention [1-4]. Despite that solar is a kind of pollution-free and renewable energy, whose collection and storage are still limited by location, climate and collector installation. Because there is a three-month heat wave from June to Therefore, a novel ground source heat pump heating system with air seasonal heat storage(GSHPASHS) is presented in this paper. The schematic diagram of GSHPASHS system is shown in Fig.1. In summer, outdoor air heat is transferred to the soil by the heat transfer fluid in the GHE. If the indoor FCU runs, the redundant heat of the room could be moved into the soil for space cooling, too. In winter,heat pump extracted the heat from the soil for heating space.

نتیجه گیری انگلیسی

To apply the GSHP heating system in severe cold areas, the air seasonal thermal storage was added to the system using the existing installations. According to the simulation results, the following conclusions can be obtained. • The GSHPASHS heating system can meet the space heating requirements of a small detached house in severe cold area. The COP is above 4 and the ACOP approximate 3. • The approximate balance of the soil energy load in a year can be realized by air seasonal thermal storage, which is favor to the GSHP operation for long. • The GSHPASHS heating system performs the good heating stability and reliability. The indoor temperature control contributes to improving the indoor temperature comfort and further saving energy.
