Detailed introduction to the use of air coolers in aquaculture farms

1、 Air cooler

The full name of air cooler is evaporative air conditioner, also known as air cooler, water cooled air conditioner, industrial air conditioner, energy-saving and environmental protection air conditioner, water air conditioner, and air conditioning fan. The power consumption per hour is only one eighth of that of traditional air conditioners. It has a history of 50 years in Australia, Europe, and the United States, and has been introduced into China for over a decade. Initially mainly used in factories and supermarkets, in recent years, with the emergence of household appliances, the range of functions of air conditioners has widened.

1. Characteristics of air cooler

Energy saving: The power consumption per hour is only 1 kilowatt hour, with low operating costs. The power consumption is only 1/10 of that of a central air conditioner, and 1/8 of that of a traditional compressor air conditioner.

Environmental protection: No freon, integrating odor removal, ventilation, cooling, temperature regulation, and humidity control.

Obvious cooling effect: generally up to 5 ℃ – 15 ℃ cooling effect, and rapid cooling.

Large air volume and long air supply distance: The hourly air supply capacity of each air cooler is 18000 to 60000, with high air pressure and long air supply distance.

2. Principio de refrigeración

When the fan is running, a negative pressure is generated in the air conditioner chamber, causing external air to flow into the porous cortina húmeda surface and enter the chamber. The water on the cortina húmeda evaporates, taking away a large amount of sensible heat, reducing the dry bulb temperature of the air passing through the wet curtain to a temperature close to the wet bulb temperature of the outside air. That is, the dry bulb temperature at the outlet of the air conditioner is 5-12 ℃ lower than the outdoor dry bulb temperature (up to 15 ℃ in dry and hot areas). The drier the air, the greater the temperature difference, and the better the cooling effect. Because the air is always introduced from the outside into the room, it can maintain the freshness of the indoor air; At the same time, due to the principle of evaporative cooling, this machine has dual functions of cooling and humidification. When used in workshops such as textile and knitting, it not only improves the cooling and humidification conditions, but also purifies the air, reduces needle consumption and wire breakage during needle spinning, and improves the quality of needle textile products.

Energy saving and environmental protection cold air machine, also known as: cold air machine, cold air air conditioner, cortina húmeda fan, wet curtain cooling machine; According to the different configuration models, various uses are generated, such as for cooling ordinary high-temperature workshops, for local air supply, for mushroom cultivation rooms, and for cooling greenhouses, poultry houses, and livestock pens.

In general, when the temperature is above 28 ° C, the human body will feel relatively hot and accompanied by sweating, especially during the scorching summer season. Many working environments and breeding and planting bases have temperatures much higher than 28 ° C. The human body, general animals, and plants are ideal in an environment of 20-25 ° C. Even simple cooling and ventilation measures cannot meet the required requirements; By using traditional air conditioning and industrial refrigeration equipment, not only does it require high equipment investment and high operating costs, but it is also limited by the open conditions of the premises, resulting in unsatisfactory results. Therefore, an energy-saving and environmentally friendly ventilation and cooling equipment and system have emerged.

Overview of air coolers

It utilizes high-tech water curtain products, based on the principle of water evaporation and heat absorption, to absorb air from the external environment, cool down, and deliver it to high-temperature areas, thereby making the environment comfortable and improving efficiency. This type of equipment not only cools down, but also has functions such as humidification, ventilation, oxygen and dust removal, air purification, and odor removal Wait for direct effects.

Principles of air coolers

Cooling principle: Due to the uniform coverage of water film on the inner wall of the cortina húmeda, when dry and hot air passes through the wet curtain, the water on the wet curtain will be trapped by the air and form evaporation. Due to the fact that evaporation is a thermal process, the temperature of dry and hot air decreases, the humidity increases, and the space air becomes cool and humid. No matter how high the original space temperature is, how thick the dust is, and how many odors there are, the cold air function can appropriately improve the space environment.

By adding air supply pipeline equipment, the goal of local air supply cooling, post air supply, station dust removal, and range odor removal can be achieved. It is more suitable for use in various harsh and unfavorable environments where the wind direction and air volume can be controlled. For example, glass lamp workshop, precision welding workshop, glass wire drawing workshop Because of these workplaces, wind can affect production and the ambient temperature is very high. Local air supply has solved a major problem that has troubled enterprises for many years.

It is not like ordinary air conditioners that use refrigeration to neutralize heat within a fixed range, such as space radiation heat, machine operation heat, human metabolism heat, animal and plant body heat respiration heat, and production combustion heat. Instead, it uses the introduction of fresh and cool air to eliminate outdated hot air in the space and carry away heat. Therefore, the higher the temperature of the space, the more obvious the effect. Of course, it is necessary to flexibly apply according to the characteristics of various industry workshops, and adjust the wind direction, air volume, and wind speed to achieve the goal of not affecting production but creating a comfortable production environment.
