Tropical fish breeding system with ground source heat pump

Abstract

The invention relates to a tropical fish breeding system with a ground source heat pump, comprising heating / cooling backwater supply loop systems, a control system and a heat-preservation fishpond. The heating / cooling backwater supply loop systems are in control connection with the control system, wherein one backwater supply loop system is arranged in the heat-preservation fishpond, one backwater supply loop system is arranged in a machine room, and one backwater supply loop system is arranged underground. Each heating / cooling backwater supply loop system comprises a ground source heat pump main engine, a circulating water pump, buried pipes, a sub-catchment device and a terminal heat exchanging device, wherein the ground source heat pump main engine, the circulating water pump and the buried pipes are mutually communicated, and the terminal heat exchanging device is arranged in the heat-preservation fishpond and is in circulating communication with the sub-catchment device and the ground source heat pump main engine. The control system comprises a direct digital controller (DDC), a temperature sensor and a terminal control unit, wherein the temperature sensor and the terminal control unit are both electrically connected with the direct digital controller (DDC). With the adoption of the tropical fish breeding system, the requirement of constant temperature for breeding tropical ornamental fish can be met, and the energy source is saved. The tropical fish breeding system has higher innovation.

Description

technical field [0001] The invention belongs to the technical field of ornamental tropical fish cultivation, in particular to a ground source heat pump tropical fish cultivation system. Background technique [0002] Industrialized aquaculture is an inevitable trend in the development of today's aquaculture industry. Some species, such as African crucian carp, tilapia, Nile tilapia and other tropical edible fish among tropical fish, have a wide range of food habits, fast growth and reproduction, and high group output. , The meat is delicious, but these fish require that the water temperature in the pits and ponds in which they live should not be lower than 25-33 degrees Celsius, and they cannot survive the winter in the northern region. They need to air fry the fry from the south every spring when the flowers bloom, and the cost increases. There are many difficulties, which undoubtedly severely restrict the factory farming of the above-mentioned varieties. In the northern re...

[0002] Industrialized aquaculture is an inevitable trend in the development of today's aquaculture industry. Some species, such as African crucian carp, tilapia, Nile tilapia and other tropical edible fish among tropical fish, have a wide range of food habits, fast growth and reproduction, and high group output. , The meat is delicious, but these fish require that the water temperature in the pits and ponds in which they live should not be lower than 25-33 degrees Celsius, and they cannot survive the winter in the northern region. They need to air fry the fry from the south every spring when the flowers bloom, and the cost increases. There are many difficulties, which undoubtedly severely restrict the factory farming of the above-mentioned varieties

In the northern region in midsummer, too high water temperature will also adversely affect the cultivation of tropical ornamental fish.
