A super-gravity air-conditioning device that can relieve the natural dormancy of deciduous fruit trees

Abstract

The invention discloses supergravity air cooling equipment capable of removing natural dormancy of deciduous fruit trees. The supergravity air cooling equipment comprises a heat exchange bucket with an opening in the upper end, an air inlet device, a cooling air outlet device and a cooling liquid inlet device are arranged on the heat exchange bucket, and a supergravity cooling liquid atomization device capable of dispersing and atomizing cooling liquid conveyed by the cooling liquid inlet device is arranged in the heat exchange bucket. According to the scheme, the heat and mass transfer mode with air and water in direct contact is adopted, the heat and mass transfer link is reduced, the water and air temperature difference is about 1 DEG C after air and water liquid are exchanged, and supports are provided for low-temperature cooling water to manufacture low-temperature air. The relative humidity of cooling air obtained after heat and mass transfer is close to the saturation relative humidity, and proper humidity can be provided for the fruit trees after the cooling air and high-temperature air are mixed.

Description

technical field [0001] The invention relates to an air-conditioning device, in particular to a high-gravity air-conditioning device capable of releasing the natural dormancy of deciduous fruit trees, which is suitable for various facility agriculture such as fruit trees. Background technique [0002] Facility cultivation can prolong the land use time, make full use of land and light energy resources, improve land utilization rate, prevent natural disasters, expand the crop planting area, extend or shorten the crop growth period, extend the market supply period, and fill the market off-season. Therefore, the market price of protected cultivation products is high, and the economic benefits are remarkable. People's enthusiasm for protected cultivation is also getting higher and higher, and the area of ​​protected cultivation is increasing rapidly. However, in the cultivation of fruit tree facilities, the cooling capacity is the main constraint factor. If the cooling capacity is...

Problems solved by technology

Due to the many links of heat and mass exchange and the large heat exchange temperature difference, the fan coil unit has a low heat exchange efficiency in the case of small temperature difference heat exchange; the fins and metal tubes need a large exchange area in the case of small temperature difference heat exchange, and the production is very slow. inconvenient

Alternatively, with R 22 When the air conditioner is used as a refrigerant to cool down, due to the low temperature and high humidity of the production environment, it is easy to frost, and the dry and cold air of the air conditioner is also easy to dry the fruit branches and affect the production.
