Abstract

The invention discloses a constant-temperature heating system of a solar greenhouse. The system comprises a solar heat collector assembly and a phase-change heat barrel heating assembly, wherein the solar heat collector assembly comprises a solar heat collector, and a heat medium output pipe and a condensate return pipe are arranged on the solar heat collector; the phase-change heat barrel heating assembly comprises a heat storage water tank, a circulating pump, a flow control valve, a phase-change heat barrel, an air blower and an air exhaust pipeline; the air blower is arranged at one end of the phase-change heat barrel, the other end of the phase-change heat barrel is connected with an air inlet end of the air exhaust pipeline, and an air guide plate is connected with an air outlet end of the air exhaust pipeline; the phase-change heat barrel comprises a casing and an inner barrel body arranged inside the casing, at least one metal heat transfer pipe is also arranged in the axial direction of the phase-change heat barrel, and one end of the at least one metal heat transfer pipe is connected with a heat source water outlet pipe. Compared with the prior art, the system has the characteristics of good heat-insulating and constant-temperature effect, capability of effectively reducing the day-and-night temperature difference in the greenhouse and the like, so that the system has the good popularization and usage value.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to the technical field of constant temperature and heating of a solar collector coupled with a greenhouse. Background technique [0002] With the concept of sustainable development put forward, energy conservation and emission reduction have also begun to attract widespread attention, and one of the major manifestations of energy conservation and emission reduction in agriculture is the greenhouse. In recent years, the greenhouse industry has developed rapidly in my country, and has become the growth point and booster of modern agricultural production, as well as the representative model and development direction of modern agriculture. As the main body in the implementation of agricultural industry in our country, the solar greenhouse industry has begun to become the most profitable industry in the agricultural planting industry. It has made historical contributions to solve the off-season su...
