Abstract

The invention discloses a multi-purpose solar energy-air source heat pump cycling dehumidification curing barn. The curing barn comprises a curing barn, a control mechanism, a heat pump heat absorption mechanism and a dehumidification mechanism, wherein the curing barn is divided into a solar energy heat collection chamber, a drying chamber and a heating chamber through an upper baffle plate and partition walls; a cycle exhaust outlet is formed on the upper baffle plate of the curing barn; a solar energy heat collecting plate is arranged in the solar energy heat collection chamber; a condenser and a second evaporator are mounted on the partition walls; a circulating fan is connected with the part of the condenser in the drying chamber; a small circulating fan is mounted on the partition wall between the solar energy heat collection chamber and the heating chamber; one end of the compressor of the heat pump heat absorption mechanism is communicated with one end of the condenser, and a first evaporator branch circuit and a second evaporator branch circuit are parallelly connected between the other end of the compressor and the other end of the condenser; and the control mechanism is used for controlling the working state of the compressor, the blower and the evaporator. Due to the adoption of the curing barn provided by the invention, the problem that the solar energy is unstable is overcome, the continuity of the drying process is ensured, the utilization rate of solar energy is further improved, and the degree of automation is high.

Description

technical field [0001] The invention belongs to the technical field of dehumidification barn, and mainly relates to a multipurpose solar air source heat pump cycle dehumidification barn. It is widely used in wood, medicinal materials, grains, food, seafood, tobacco leaves and other fields that require dehumidification and drying. Background technique [0002] Solar energy is widely favored by researchers at home and abroad for its advantages of low cost of use, energy saving and environmental protection, and huge energy. However, due to the discontinuity of solar energy and the dependence on weather, ordinary solar heat pumps cannot work normally at night and in continuous rainy days, thereby reducing the working efficiency. Closed air source heat pump drying is based on the reverse Carnot cycle principle, using a small amount of electric energy to drive the compressor to run, the refrigerant gas is compressed in the compressor, the temperature and pressure are increased...
