寒区太阳能_土壤源热泵系统太阳能保证率的确定

在寒冷地区以太阳能、土壤源作为热泵的低位热源对节约能源、保护环境、开发利用新能源和可再生能源具有重大的意义。文中首次提出了土壤源热泵系统在不同的运焦比下的土训温度场恢复率，并以此为指标，衡量土壤源热泵在各种不同运停比下土壤温度场的恢复程度，确定土训源热泵的最佳运停比及太阳能保证率，从而确定太阳能集热装置的容量。

Determination of the Solar Energy Assurance Factor of a Solar Energy - Ground Soil-source Heat Pump System in Frigid Regions

In frigid regions the use of solar energy and ground soil-source heat as a low-level heat source of heat pumps is of great significance from the perspective of environmental protection and the development and utilization of new and renewable energy sources. The authors have for the first time put forward the concept of ground-soil temperature restoration rate of the ground soil-source heat pump system under different ratios of operation/shutdown. With the above-cited restoration rate serving as an index the restoration degree of ground soil temperature field is evaluated of the ground soil-source heat pump under various operation/shutdown ratios. On this basis, the optimum operation/shutdown ratio of the said heat pump and solar energy assurance factor were identified, and thereby the capacity of solar energy heat-collection device was determined.
