Multi-heat-source drying room system with geothermal pipe and double dehumidification devices

Abstract

The invention discloses a multi-heat-source drying room system with a geothermal pipe and double dehumidification devices. The multi-heat-source drying room system adopts three heat sources, i.e. solar, air energy and electric heating pipes, to heat air inside a heat preservation drying room and comprises the independent dehumidification devices which do not depend on air energy and solar energy, a device for carrying out condensation dehumidification and preheating on air entering the drying room by utilizing air energy, and a geothermal device for storing and utilizing residual solar energy; and a defrosting device which utilizes air energy is added in an air energy system. According to the invention, the defect of instability of solar energy is overcome, the utilization rate of solar energy is effectively improved, the multi-heat-source drying room system is energy-saving and environmental-friendly, has a wide application range and can be suitable for the cold environment, and the temperature and the humidity in the drying room can be effectively kept.

Description

technical field [0001] The invention relates to a barn system for dehumidification and drying of wood, medicinal materials, grains, food, seafood, tobacco leaves, etc., especially a barn system using solar energy and air energy with multiple heat sources, geothermal pipes and double dehumidification devices system. Background technique [0002] Solar energy has the advantages of low cost of use, energy saving and environmental protection, and huge energy, but it also has the disadvantage of instability because of its discontinuity and dependence on the weather, so it needs to be used in conjunction with other heat sources. Air energy is a low-quality heat energy, which needs to be converted into high-quality usable heat energy with a small amount of electric energy to drive the compressor. Compared with ordinary electric heating methods, it still has the advantages of low cost, energy saving and environmental protection. In the current situation of conventional energy short...

Problems solved by technology

[0003] At present, the application of solar energy and air energy in the barn system is becoming more and more mature. However, in most of the barn systems today, the solar collectors are directly installed on the top of the barn, which is used as a heating system similar to electric heating. The heat source of the tube is used, which limits the location of the barn, and at the same time, the heating is uneven, which reduces the efficiency; the dehumidification function is mainly realized by the air energy system. When the solar energy is sufficient and the air energy is not needed, a good performance cannot be achieved. Dehumidification effect; because the evaporator of the air energy is located outdoors, it is easy to frost when the outdoor temperature is low and affects the use; when cooling or ventilating the barn, it is usually directly introduced into the outside air, so that the dryness in the barn It is not easy to maintain, and re-drying will increase energy consumption; when the heat provided by solar energy is greater than the required heat, it is often necessary to cool down at the same time or reduce the heat-absorbing area of ​​the solar device, which is inconvenient to use and causes energy waste
