What are the cooling equipment in pig raising equipment?

Pig farms need complete pig raising equipment. With pig raising equipment, the pig raising process will get twice the result with half the effort, and the future income will be greater. Today, I will introduce the cooling equipment of pig raising equipment. There are three kinds of cooling equipment of pig raising equipment. Here are three kinds of cooling equipment in detail:
(1) Wet curtain cooling system
The system is mainly composed of wet curtain and fan.
Generally, there are two types of wet curtain: ordinary medium and reinforced medium. Ordinary medium is made of corrugated fiber paper. Through filling special chemical composition and special post-processing in the raw material of papermaking, it has the characteristics of corrosion resistance, high strength and long service life. The reinforced medium is a special process to add black hard coating on the surface of ordinary medium, which makes the paper pad easy to wash and disinfect, effectively solves the problems of various flying flocs in the air, and has the advantages of light shielding, rat resistance and longer service life. Wet curtain cooling system is to use the principle of heat exchange to humidify and cool the air. The water is sent to the top of the wet curtain through the water supply system, so as to wet the surface of the wet curtain. When the air passes through the wet curtain, the water and the air are fully contacted, so that the air temperature is reduced, so as to achieve the purpose of cooling, and the cooling effect is significant. In summer, the temperature can be reduced by 5-8 ℃, and the higher the temperature is, the greater the cooling range is. With less investment and low energy consumption, it is called "cheap air conditioning". Fresh air, balanced cooling, humidity can be adjusted to the best state. Wet curtain ventilation has low investment and high efficiency, which is especially suitable for aquaculture.
(2) spray cooling system
The system is composed of various types of atomizing nozzles and pressure pumps connected on the pipeline.
The spray cooling system is a highly efficient evaporation system, which uses small sprinklers to spray small droplets into the piggery. With the increase of humidity, heat energy (solar light + pig body heat) is converted into evaporation energy, and the temperature drops to the required value in a few minutes. As the water sprayed is absorbed by the air in the house, the ground is always dry. This system can be used for disinfection at the same time, so as to improve the health of pigs. As the system can effectively cool down, it can reduce the ventilation to save energy. When the small environment climate in the building is required to be both suitable and sanitary, it can be used all year round. This system has the characteristics of summer cooling, spray dust removal, continuous humidification, environmental disinfection, and fresh air control throughout the year.
(3) Cooling fan
The utility model has the advantages of good cooling effect, moist purified air, low pressure, large flow, low power consumption, low noise, fast refrigeration, stable operation, safe and reliable operation, low operation cost, simple operation and convenient maintenance.
