Bulk curer heat supply and ventilation system supplied by combined solar energy-air source heat pump double heat sources

Abstract

The invention discloses a bulk curer heat supply and ventilation system supplied by combined solar energy-air source heat pump double heat sources, which consists of a solar water heating subsystem, an air source heat pump water heating subsystem, an air-water heat exchanger, a frequency conversion circulating water pump, a heat insulating hot water pipeline, a main controller, a circulating fan, an air supply pipe, a fresh air valve and a curer wet air outlet. A condenser of the air source heat pump water heating subsystem is arranged in a heat accumulating water tank; the air source heat pump water heating subsystem is coupled with the solar water heating subsystem through the heat accumulating water tank; and the air source heat pump water heating subsystem adopts a CO2 high temperature refrigerant to prepare high temperature hot water between 85 and 90DEG C. The bulk curer heat supply and ventilation system adopts the solar water heating system and the air source heat pump water heating system, which are combined to operate, to supply heat to the curer, fully utilizes the clean solar energy and low-grade heat energy in the atmosphere, has the advantages of energy conservation, environmental protection and the like, and can realize loss minimization and value addition in the process of curing tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf preparation equipment, in particular to a heat supply and ventilation system for a dense barn using a solar heat collector and an air source heat pump for joint heat supply. Background technique [0002] The heating and ventilation system is the core component of the intensive curing barn. It directly affects the heating rate of the barn, the temperature distribution in the barn and the energy consumption of tobacco leaves. It is one of the most critical factors that determine the quality and energy consumption of tobacco leaves. . The energy-saving and environment-friendly heating and ventilation system of the barn can effectively reduce the loss and increase the value of tobacco leaf curing, which meets the development requirements of modern agriculture to replace resources with technology. [0003] At present, intensive barns usually use coal, oil or other biomass energy as energy sources...
