Abstract

An energy-saving and environment-friendly electric heating draught fan is used for heating and temperature rise in agriculture planting greenhouses in freezing winter in high-altitude countries and regions. The energy-saving and environment-friendly electric heating draught fan comprises a heat exchange box body, a heating pipe, a heating substance in the heating pipe, and a high-speed draught fan. According to the energy-saving and environment-friendly electric heating draught fan, the heating substance is activated through electricity, so that the heating substance releases latent heat, and the electricity-heat conversion efficiency is improved. The heat efficiency of the energy-saving and environment-friendly electric heating draught fan produced through the technology that the heating substance is activated through electricity to release the latent heat reaches 365.76%. The energy-saving and environment-friendly electric heating draught fan with the input power being 10.8 kW is installed in a standard agriculture planting greenhouse with the area being 666 square meters. The temperature in the greenhouse reaches 17 DEG C under the condition that the environment temperature is -10 DEG C, and the requirements for growth of vegetables, melons and fruits, and flowers can be met. Energy is saved by about 80% compared with an ordinary electric heating draught fan.

Description

technical field [0001] The invention belongs to the technical field of electric heating equipment, and in particular relates to an energy-saving and environment-friendly electric heating fan. Background technique [0002] The advent of agricultural planting greenhouses is a major breakthrough in agricultural planting technology for thousands of years. It fundamentally changes the traditional planting season, making it possible to grow off-season crops, and enables ordinary people in high-latitude countries in the world to eat fresh vegetables and fruits in the severe winter. However, the normal growth of crops must be satisfied in the severe cold winter in the agricultural planting shed. At present, the national agricultural planting greenhouse basically adopts clean and environmentally friendly electric heating. The input power of electric heating for a standard agricultural planting greenhouse per mu (666 square meters) is 50kW, the heating time is 14-16 hours per day, an...
