Seasonal soil heat storage and release-based solar-heat pump heating system for industrial turtle raising field

Abstract

The invention discloses a seasonal soil heat storage and release-based solar-heat pump heating system for an industrial turtle raising field, which consists of an air heating system, a soil heat storing system, a breeding water heating system and a soil heat releasing system, and is characterized in that: on the basis of a 'solar-heat pump combined heating system for industrial turtle raising field' which is registered in China Patent with a number of ZL200810061011.5, soil heat storing and releasing systems are added, and the characteristic of high heat storage capacity of the soil is used to realize seasonal temperature adjustment in the turtle raising field. Compared with the prior art, the system has the advantages of storing heat collected by a solar heat collector in summer and supplying heat to a heating system of a green house in the turtle raising field in winter when solar is insufficient.

Description

technical field [0001] The invention relates to solar heat utilization technology, heat pump technology and seasonal soil heat storage and release technology, in particular to a seasonal soil heat storage and release solar energy-heat pump heating system used in industrial turtle farms. Background technique [0002] According to the growth characteristics of soft-shelled turtles, the heating time of soft-shelled turtle greenhouses in most areas of my country is as long as 9-10 months throughout the year, which inevitably consumes a lot of energy. In order to save energy and reduce emissions, Chinese patent CN200810061011.5 provides a solar-water source heat pump combined heating system used in industrial turtle farms. The system uses solar energy as the main heat source, and uses part of the waste water pool in the season when the solar radiation is insufficient. As a supplement, energy has the advantages of not affecting the environment and ecology, good energy saving and e...

Problems solved by technology

But there are also some deficiencies. For example, in hot summer, the turtle farm does not need to be heated, and a large amount of high-temperature hot water produced by the solar collector group cannot be used, which makes the water temperature in the solar collector group rise higher and higher, and produce A large amount of steam, if it is the case for a long time, not only wastes the energy collected, but also affects the service life of the equipment
