A solar greenhouse ventilation heat recovery system and a solar greenhouse equipped with the system

Abstract

The invention relates to the technical field of agricultural sunlight greenhouse systems, in particular to a sunlight greenhouse ventilation and heat recycling system and a sunlight greenhouse with the same. According to the sunlight greenhouse ventilation and heat recycling system and the sunlight greenhouse disclosed by the invention, one or more groups of Trumbo chimneys are mounted in the greenhouse; the chimneys are fixed to the sunny side of a heat collecting wall; an air current channel is arranged in each group of the Trumbo chimneys, and is used for heating air in the corresponding air current channel through sunlight to drive the air in the air current channel to be heated and flow; a heat exchanger is mounted in a drainage cavity in the air current channels, and is used for absorbing heat quantity of the heated air; and a heat storing and heat emission assembly is connected with the heat exchanger, and is used for storing heat quantity and emitting the heat quantity to the greenhouse. According to the sunlight greenhouse ventilation and heat recycling system disclosed by the invention, a natural ventilation manner is adopted, and the thermal air in the greenhouse is introduced into each Trumbo chimney with a hollow structure; excessive heat energy of the air is stored in a heat storage water tank in a fluid medium manner through heat exchanging, so that the temperature of the greenhouse is adjusted through buried pipes.

Description

technical field [0001] The invention relates to the technical field of agricultural solar greenhouse systems, in particular to a solar greenhouse ventilation heat recovery system and a solar greenhouse equipped with the system. Background technique [0002] Although since the new century, the concepts of green agriculture and ecological agriculture have been put forward repeatedly. However, in view of the current price of natural gas, the majority of solar greenhouses usually need to use coal to increase the temperature in winter, so as to reduce the freezing damage or chilling damage of indoor fruits and vegetables. At the same time, combined with the smog situation in winter in the northern region, different regions have adopted different measures to deal with the governance of the atmospheric environment. Energy saving and emission reduction are getting more and more attention in greenhouse production. [0003] In order to realize the active use of solar energy, the sol...

AI Technical Summary

Problems solved by technology

The deep material in the heat storage wall fails to play an effective role, and the heat storage capacity is limited. Excessive heat energy during the day is usually discharged out of the greenhouse through ventilation, and has not been effectively utilized.
