A self-regulating farming system

Abstract

The invention relates to an automatic regulation and control type culture system, which comprises at least one culture shed, a ground source heat pump system, a solar heat collector, an energy-saving coal-firing boiler, a water circulation pipeline and a central controller, wherein the central controller is used for controlling the constant temperature of a culture tank, the ground source heat pump system, the solar heat collector and the energy-saving coal-firing boiler are coupled, the problem of a series of harsh requirements on agricultural culture environment is solved, the conventional low-energy-efficiency and high-emission method adopting a small-size coal-firing boiler for heating and heat insulation is replaced, a ground source heat pump technology and a solar energy heat collection coupling utilization technology are successfully used in special-environment agricultural aquaculture facilities for temperature regulation.

Description

technical field [0001] The invention belongs to the technical field of air conditioning in the breeding industry, and specifically relates to an energy-saving and environment-friendly temperature control system in a breeding greenhouse, which solves the problem of uniform heating and uniform temperature distribution in the breeding greenhouse to ensure a good breeding environment. Background technique [0002] Traditional aquaculture greenhouses use coal-fired boilers for heating, which not only bears the cost pressure of rising coal prices, but also causes serious air pollution. [0003] There are also solar-assisted breeding systems in the existing technology, because my country is located in the northern hemisphere, most areas are located south of 45° north latitude, the annual sunshine hours are about 2000h or more, and the total solar radiation in various places is about 3.4-8.4 billion J / m 2 a, with abundant solar energy resources. The sun emits energy in the form of ...

Problems solved by technology

However, solar energy has two deficiencies: one is that the energy flow density is low; the other is that its intensity cannot be maintained constant due to the influence of various factors (day and night, cloudy, rain and snow, etc.). It is also proposed to use heat pump energy, but ground source heat pump In long-term operation, the soil temperature field will not be restored in time, the evaporation temperature and condensation temperature will fluctuate greatly, and the operating efficiency of the heat pump unit will be low

The patent only proposes to increase the choice of two systems of solar energy and ground source heat pump as a cold source or a heat source, and there is no specific implementation method
