Abstract

Abstract: Greenhouse, as the main part of facility agriculture, is particularly important to adjust the temperature in the growing environment. Through the ground source heat pump air conditioning system, the greenhouse stored heat across seasons. It had the advantages of high efficiency, energy saving, cleanliness and environmental protection. A greenhouse in Beijing and its source heat pump air conditioning system were used as the research objects to analyze the operating performance of cross-season heat storage system in the greenhouse. DeST software was used to modeling and analyze the variation of load and room temperature and determine the operating characteristics of the system. Combined with the actual engineering data, the operation effect of ground source heat pump air conditioning system was explored, and the stability of the system was analyzed. The results showed that the total heat and cold load ratio of the whole year was 1.0:1.1. The room temperature of the greenhouse was maintained at 20.0-25.0 ℃, which could meet the growth temperature requirements of high-grade flowers. The water inlet temperature on the source side of the heat pump was maintained at 11.4-23.7 ℃, which met the requirements of relevant specifications. The annual soil temperature of buried pipes increased by 1.3 ℃, and the change of soil temperature was relatively stable. The ground source heat pump system worked well in greenhouse and was stable. It had good economic, energy saving and emission reduction benefits.

Key words: greenhouse, inter-seasonal energy storage, ground source heat pump system, running effect
