Multifunctional drying system integrating solar energy and heat pump

Abstract

The invention discloses a multifunctional drying system integrating solar energy and a heat pump. The system comprises a solar heat collector, a plurality of valves, a storage water tank, a drying room, a circulating fan, a coil pipe mounted on the wall in the drying room, a segregation board, a circulating water pump, a condenser, a compressor, an evaporator, an expansion valve, an air inlet fan and an air exhausting fan. The system combines the characteristics of the solar energy and the power supply of the heat pump, so that the continuous drying operation can be performed in different weather conditions; three running modes, including a solar energy-storage heat-supply mode (single), a heat pump drying de-humidifying mode (single) and a solar energy heat pump combined energy-storage heat-supply mode, can be realized by switching or combining the multiple energy-supply modes by the system; the system has the advantages that the temperature in the drying room is relatively uniform; the problems of hot air dead space and non-uniform distribution of the indoor temperature existing in a conventional drying room are solved; the energy-saving effect is good; the functions of the heat pump and the solar energy are taken fully used; when the drying room is not in work, the drying room can be used for supplying hot water for accumulating heat and warming, so that the drying system is multifunctional and the function of the drying system is brought into full play.

Description

technical field [0001] The invention relates to a drying system, in particular to a multifunctional drying system integrating solar energy and a heat pump, and belongs to the technical field of solar heat utilization. Background technique [0002] my country's energy demand pressure, greenhouse gas emissions and fuel price increases have prompted people to vigorously develop renewable energy. Solar energy is considered as an ideal energy source to solve the current energy crisis and environmental pollution because of its abundant resources and environmental friendliness. With the maturity of solar thermal utilization technology, the connection between the development and utilization of solar energy and people's production and life is getting closer. Among them, solar drying has gradually attracted attention because of its characteristics of energy saving, pollution-free, and environmental friendliness. [0003] Most of the existing solar drying systems collect heat energy ...
