Description
Technical Field
The invention relates to the field of culture pond temperature control equipment, in particular to a culture pond system with circulating water temperature adjustment.
Background
Compared with the traditional aquatic product culture mode, the circulating water culture mode has the advantages of less pollution, less water resource consumption and less dependence on the environment due to the optimization of a series of systems such as a water treatment system, a water body temperature regulating system and the like, but the water body temperature control and the operation cost of the circulating water culture become key problems.
The solar energy resources in China are rich, the annual average total radiation in most areas is close to 5000 MJ/square meter, the annual average illumination time is 2200 hours, so that the solar energy is a good water heating resource, and the solar energy is taken as the most expected green energy for the human in the 21 st century, so that the solar energy is widely accepted; solar energy, while energy-saving and environmentally friendly, also because of its instability and intermittence, requires energy complementation with solar energy using another temperature regulation mode, which is a heat pump technology. The heat pump can convert a large amount of low-grade heat energy into high-grade heat energy at the cost of consuming a small amount of electricity. Meanwhile, due to the structural specificity of the heat pump, the temperature reduction in summer can also be realized; the electricity consumption at the trough is changed to attract users to use electricity at the trough at night according to the document spirit of the combined text of the economic trade committee of the material price office and the electric power industry office, and the electricity at the trough is only 1/3 of the electricity price at the peak at the trough at night, so that enterprises can convert the electricity at the trough into heat energy by using an energy storage technology and store the heat energy for use in the daytime; the fresh water make-up water generally only accounts for 2% -10% of the total volume of the culture pond, the required load accounts for 4% -20% of the total load, if the fresh water make-up water is directly injected into the circulating water system for direct temperature adjustment, the accuracy of temperature system adjustment and control can be influenced due to overlarge temperature difference, and if a temperature control system is independently provided for the fresh water, or the complexity of system control is increased due to inconsistent temperature control systems.
The existing circulating water culture pond system generally only adopts a heat pump to supply heat or cool, the consumed energy is generally electric power, and no means of energy compensation and energy storage is provided, so that the energy utilization rate is very low, and the operation cost is high; and the temperature adjusting ability in winter and summer is not strong. For example, chinese patent CN108849698A discloses a constant temperature aquaculture pond using a heat pump, which uses the heat pump as a main cold source and a heat source of the aquaculture pond, and auxiliary electric heating as a standby heat source, so as to ensure the annual constant temperature of the aquaculture pond.
