With the increase in temperature, the air-conditioning usage rate is increasing all over the country. However, it is necessary to prevent air-conditioning diseases while receiving the coolness of air-conditioning manufacturing for a long time. Therefore, equipment such as chillers that are both cooled and clean air is accepted by more and more people.
People suddenly enter the air-conditioned room in an outdoor environment where the temperature is too high. The body needs to be switched quickly in a sudden temperature change environment. The relatively cold sensory transmission stimulates sympathetic excitation, the vasoconstriction of the abdominal cavity, the gastrointestinal motility is weakened, and the limbs appear. Numbness, dry skin and other symptoms. In addition, since the air in the air-conditioned room cannot be circulated, it is easy to cause dizziness, nausea, weakness, and the like. And in order to avoid the occurrence of these symptoms, how to do it? In addition to using as little air conditioning as possible, to maintain indoor air circulation, is there any other way?
A cooling fan can be used for indoor cooling. The air cooler is a cooling device between the air conditioner and the fan. It can also be said to be a modified version of the fan. Compared with the traditional air conditioner fan, the cooling effect is improved by nearly half, and the air can be cleaned while cooling. The function effectively solves the problem that the air inside the air-conditioned room cannot be circulated and the air quality is poor.
The ventilator inside the air cooler introduces the outdoor air. When it passes through the wet curtain, the air in the air will be cleaned, the water pump will also clean the air, and then the clean and fresh air will be sent to the indoor through the fan. When the air is exhausted, the air cooler achieves the effect of cooling down and purifying the air. Wet curtain air coolers are generally used for cooling down the plant, cooling and ventilating, removing dust and odor in the air, which is the first choice for many workshops.

Regarding the air cooler, there are wet curtain air coolers in front, etc. Below, we will come to familiarize with another type, which is an evaporative air cooler, which can also be called an environmental air conditioner, an air conditioner air cooler and an evaporative air cooler. Its main role is that ordinary air coolers are cooled for ventilation. Moreover, it also has functions such as dustproof and deodorizing. Therefore, it can be considered as an evaporative cooling and ventilation unit.

   1. The use conditions and environmental requirements of the evaporative cooling fan

   For the evaporative cooling fan, the conditions of use are as follows:
   Temperature: 18 ° C - 45 ° C

   Relative humidity: 85% or less.

   Atmospheric pressure: 86kpa—106kpa

   Water supply: The water should be softened, and the water supply temperature should not exceed 45 °C, and the water supply pressure is 0.15-0.6 MPa.

   Power supply: The deviation of the power supply voltage should not exceed 5% of the rated voltage.

   For the environmental requirements of evaporative cooling fans, the main requirement is that there are no corrosive gases or substances in the environment, and there should be no open flame or fire source to avoid danger.

   2. Precautions for evaporative cooling fan

   (1) When connecting the inlet pipe and the drain pipe, the connection should be correct and good, and there should be no leakage or leakage, so as to avoid damage to the air cooler or serious consequences.

   (2) On the evaporative cooling fan, no items can be placed to avoid affecting the heat dissipation of the device or its damage.

   (3) For the maintenance work of the chiller, it should be carried out under the power-off state, and it should not be carried out during its operation, because it is very dangerous and it is easy to get an electric shock.

   (4) In the course of use, if there is any abnormality, it should be stopped immediately and handled by professional maintenance personnel. It is strictly forbidden to handle it without authorization or privately.

   (5) For the power cord, it should be connected correctly and firmly, and also have a good grounding treatment to ensure its safe use and operation. In addition, if there is dust, dust, or particulate matter in the air, a filter can be added to protect it.

That is, the dry bulb temperature at the exit of the cooling fan is 5-12 °C lower than the outdoor dry bulb temperature (up to 15 °C in the dry heat zone), the hotter the air is, the larger the temperature difference is, the better the cooling effect is.

Since the air is always introduced into the room from outside, this time is called the positive pressure system, so it can keep the indoor air fresh. At the same time, because the machine uses the principle of evaporation and cooling, it has the dual functions of cooling and humidifying (relative temperature can reach about 75%). ), used in textile, knitting and other workshops, not only can improve the temperature and temperature increase conditions, but also purify the air, reduce the needle breakage rate in the needle spinning process, and improve the quality of the needle textile products.

The air cooler is surrounded by a honeycomb wet curtain with special materials, which has a large surface area, and the wet curtain is continuously humidified by the water circulation system; the high-efficiency low-noise energy-saving fan is installed in the wet curtain air cooler, and the air is wet when the fan is running. The negative pressure generated by the curtain air cooler causes the air outside the machine to flow through the porous wet curtain into the machine, and the heat of the water on the wet curtain absorbs the heat, forcing the air passing through the wet curtain to cool down.

At the same time, since the water on the wet curtain evaporates toward the air flowing through the wet curtain, the humidity of the air is increased, so the wet curtain air cooler has the dual functions of cooling and humidifying.

The most important thing consumers pay when choosing a chiller is quality, because only the use of high-quality chillers can achieve the desired results, so the chiller plant should pay more attention to the production, and need to take correct measures to ensure the cold air. The quality of the machine. So, how does the chiller plant ensure the quality of the chiller? The following is an introduction to this problem.
The design before the production is very important: before the production of the chiller factory, pay more attention to the design, must be strictly designed according to the needs of consumers, in order to ensure the rationality of the design, and the production can be designed according to the design requirements. This can also effectively prevent the occurrence of mistakes, and the quality of the produced chiller can be well guaranteed.
The production process should be advanced: in order to ensure the quality of the chiller, the chiller factory should ensure the advanced production process, so that the quality of the chiller produced is guaranteed, and such chillers will get more in the market. The recognition of consumers is also due to the fact that manufacturers must pay more attention to the production process, and must ensure the advanced production process.
The chiller plant needs to take correct measures to actively improve the quality of the chiller. Such chillers can be trusted by consumers, which is also very helpful for the development of the enterprise.
