Low-carbon energy-saving method for reducing temperature of livestock shed in summer

Abstract

A low-carbon energy-saving method for reducing the temperature of a livestock shed in summer belongs to the technical field of livestock shed cooling in summer. The livestock shed adopts a greenhouse structure made of galvanized steel pipes and having a width of larger than 8m and a height of larger than 4m, is covered by a plastic light transmission film with water proof and heat insulating properties, and is covered by a sunshade net for shading strong sunlight on the roof and gable wall surfaces at a height larger than 1.5m from the ground. The invention adopts the building technique of the greenhouse made of galvanized steel pipes, and the livestock shed roof is covered by the plastic light transmission film and sunshade net material; ventilation openings being able to open and close are arranged on northern and southern walls of the livestock shed, and a ventilation skylight being able to open and close is arranged on the top of the livestock shed southwards and is opened or closed by drawing a longitudinal scroll; blower fans are arranged on eastern and western gables of the livestock shed for supplementing ventilation; and a medium-pressure atomization spray cooling system is arranged above a livestock barn in the livestock shed, and drops the temperature by spraying when the temperature inside the livestock shed is higher than 34 DEG C. The invention has good cooling effect and high speed, greatly lowers construction and maintenance cost of livestock sheds and cooling facilities compared with the prior art, and at the same time has remarkable energy saving and water saving effects.

Description

technical field [0001] The invention relates to a low-carbon and energy-saving summer livestock house cooling method, which belongs to the technical field of summer livestock house cooling. Background technique [0002] Existing livestock houses are similar in structure to ordinary houses, and mostly adopt brick-wood or color-steel structures. This kind of livestock house has a long construction period and high construction cost. At the same time, there are heat insulation, poor heat preservation effects, and ventilation and cooling effects. In order to cope with the high temperature in summer, such livestock houses need to be equipped with fans, wet curtain-fans, spray cooling systems and other equipment, which to a certain extent make up for the small ventilation area and heat insulation However, such ventilation and cooling facilities also have problems such as high construction and maintenance costs, high energy consumption and water consumption. For example, although t...

[0002] Existing livestock houses are similar in structure to ordinary houses, and mostly adopt brick-wood or color-steel structures. This kind of livestock house has a long construction period and high construction cost. At the same time, there are heat insulation, poor heat preservation effects, and ventilation and cooling effects. In order to cope with the high temperature in summer, such livestock houses need to be equipped with fans, wet curtain-fans, spray cooling systems and other equipment, which to a certain extent make up for the small ventilation area and heat insulation However, such ventilation and cooling facilities also have problems such as high construction and maintenance costs, high energy consumption and water consumption. For example, although the spray cooling technology has a good cooling effect, it will cause damp water in the pen, Promoting the breeding of mosquitoes, bacteria, and polluted air
