Solar heat collection system for solar greenhouse available annually

Abstract

The invention discloses a solar heat collection system for a solar greenhouse available annually. The solar heat collection system for the solar greenhouse available annually comprises the greenhouse,a buried water pipe, a solar heat collection plate and a heat preservation water tank, wherein the greenhouse is composed of a heating chamber and a control chamber; the buried water pipe is buried in the heating chamber; the two ends of the buried water pipe are each connected with a water distributor; the solar heat collection plate is arranged on the top of the greenhouse and provided with theheat preservation water tank in a pipeline connection mode, and a first circulation pump is arranged between the heat preservation water tank and the solar heat collection plate in a pipe connectionmode; the heat preservation water tank and each water distributor communicate through a pipeline provided with a second circulation pump; the heat preservation water tank is provided with an electricheating wire, a temperature sensor and a temperature control cabinet; and the side wall of the heating chamber is further provided with an induced draft fan, a fan coil pipe and an air inlet. According to the solar heat collection system for the solar greenhouse available annually, cyclic heating on soil in winter is more uniform and stable; through position design of the solar heat collection plate and the heat preservation water tank, frost cracking of pipes in winter is avoided; and the system can be effectively utilized for sterilizing soil in summer, drying vegetables and the like, is efficient and saves energy.

Description

technical field [0001] The invention relates to a solar heat collection system, in particular to a solar heat collection system for a solar greenhouse that can be used throughout the year. Background technique [0002] From the perspective of solar energy utilization, a solar greenhouse is an agricultural production facility that utilizes solar energy. However, Xinjiang is located in the alpine region of Northwest China, so it is difficult to survive winter production only by relying on the solar greenhouse itself, that is, the front roof for lighting, heat storage in the wall, heat insulation and so on. In terms of solar greenhouse research, on the one hand, it is necessary to optimize the structure of the greenhouse roof and walls, to increase the amount of light transmission, wall heat storage, and thermal insulation performance of the insulation quilt as much as possible. The heat collector is used to collect heat and introduce the collected heat into the interior of th...
