The dehumidification principle of a rotary dehumidifier is based on the use of a rotating wheel that contains a hygroscopic material. As air passes through the wheel, the hygroscopic material absorbs moisture from the air. The wheel then rotates to a regeneration section where heat is applied to evaporate the absorbed moisture, allowing the wheel to dry out before it continues to absorb moisture from the incoming air. This process effectively reduces the humidity level in the air.

What maintenance measures should we take to prevent the performance decline of explosion-proof air conditioners?

Mar 11,2019

We all know that explosion-proof air conditioners are a type of explosion-proof electrical equipment, with working environments classified into high temperature, low temperature, ultra-high temperature, and ultra-low temperature. Explosion-proof air conditioners are mainly used for cooling and heating in flammable and explosive environments such as petroleum, chemical industries, military units, oil depots, and offshore oil platforms. The appearance and usage of explosion-proof air conditioners are similar to those of ordinary air conditioners. However, in our daily lives, it is very important to maintain and service explosion-proof air conditioners to prevent a decline in performance and extend their service life. Let's take a look at the following points: 1. Regularly clean the air filter. Generally, after 2 to 3 weeks of use, the air filter should be cleaned once. When cleaning, pull the handle of the filter to remove it from the back of the panel, use a vacuum cleaner to suck out the dust from the filter mesh, and then wash it with clean water below 40°C. If there are oily substances, it can be cleaned in soapy water or a neutral detergent solution, then rinsed with clean water, and completely dried before reinstalling it back onto the explosion-proof air conditioner. Clean the panel and casing. Regularly wipe off dust and dirt from the panel and casing with a soft cloth. If it is too dirty, you can use a soft cloth dipped in soapy water or wipe with warm water below 45°C, then dry it with a soft cloth. Avoid using gasoline, kerosene, or chemical agents for cleaning. 2. Regularly clean the dust from the condenser fins. To prevent excessive dust accumulation on the air conditioner's condenser, which can affect the heat exchange capability of the explosion-proof air conditioner, the fins of the condenser should be cleaned with a vacuum cleaner or a portable blower about once a month to facilitate heat dissipation. For explosion-proof heat pump air conditioners, during snowy days in winter, snow accumulation around the unit should be promptly cleared to avoid affecting its working efficiency. When the air conditioner will not be used for more than a month, it should be run in a dry weather for about 2 hours to ventilate and dry the inside of the air conditioner before unplugging the power supply. 3. Before starting the explosion-proof air conditioner after a long shutdown, check the following items: 1. Check if the ground wire is broken or properly connected. 2. Check if the air filter is properly installed. 3. Check if the power supply is properly connected; if not, plug it in.

The difference between an explosion-proof dehumidifier and an air conditioner is that an explosion-proof dehumidifier is specifically designed to remove moisture from the air in environments where there is a risk of explosion due to flammable gases or dust. It operates by condensing moisture from the air without cooling it significantly, while an air conditioner not only dehumidifies but also cools the air by circulating it over cold coils. Additionally, explosion-proof dehumidifiers are built with materials and components that prevent sparks and ignition, making them suitable for hazardous locations.

The general working principle of explosion-proof dehumidifiers is to utilize the moisture in the air, which condenses into frost when it enters the evaporator of the dehumidifier, then accumulates and drips out, draining into the sewage outlet, thereby achieving the purpose of reducing humidity in the space. This principle is similar to the dehumidification principle of air conditioners in cooling mode. After condensing the air into water, it is discharged, balancing the indoor air temperature. The dehumidification principle of air conditioners differs from that of dehumidifiers. As can be seen, the dehumidification principle of air conditioners is actually similar to that of general dehumidifiers. But why is it still necessary to purchase a dehumidifier? Because the convenience of moving dehumidifiers and their professional dehumidification effect cannot be compared to the "side effect" dehumidification function of air conditioners. Air conditioners are fixed in position, and the dehumidification function that accompanies cooling does not significantly reduce indoor humidity in a short time. Therefore, the dehumidification function of air conditioners is actually limited, and for dehumidification and moisture prevention, purchasing a dehumidifier is the best strategy. Moreover, the working method of dehumidifiers is to cool the air inside the machine, extracting moisture from the air, which may slightly raise the temperature of the space, but the temperature difference is not significant, making it more suitable for humid seasons outside of summer, and it is relatively energy-saving. Many users often ask: "Can’t air conditioners also dehumidify? With an air conditioner, isn’t a dehumidifier redundant?" In fact, this is a consumer misconception. The main functions of air conditioners are cooling and heating. Air conditioners with independent dehumidification functions can dehumidify, but the amount of dehumidification is small and slow. Moreover, during the rainy season in southern regions, the temperature is not high, and using an air conditioner to dehumidify will blow out cold air, making it feel increasingly uncomfortable as the humidity is removed. Additionally, since air conditioners are fixed in position, they can only dehumidify a small localized area. Long-term dehumidification operation of air conditioners will also increase the load on the compressor, leading to high energy consumption and potential damage to the compressor, shortening the lifespan of the entire unit. Therefore, air conditioners are not suitable to replace dehumidifiers. 1. By usage scenario: For residential environments, using air conditioners for dehumidification should be more economical, as the suitable humidity for people is between 60-70%, which is relatively easy for air conditioners to achieve. The noise of explosion-proof dehumidifiers is greater than that of air conditioners, especially for high-power explosion-proof dehumidifiers, so air conditioners are preferred for residential dehumidification. 2. By usage objects: For industrial products such as optical lenses, magnetic recording materials (including discs), photographic films, electronic information media, electronic components, instruments, gauges, powder materials, paper, wood, silk, leather, tobacco, food, tea, and grains that require strict humidity control, using specialized explosion-proof dehumidifiers is more effective. Industrial dehumidifiers, workshop dehumidifiers, and warehouse dehumidifiers are recommended. 3. By regional climate conditions: Common climates include the following: (1) high temperature and high humidity—sultry weather in summer; (2) high temperature and low humidity—dry and hot seasons in northern climates; (3) low temperature and high humidity—rainy seasons in southern regions; (4) low temperature and low humidity—typically refers to cold weather in northern regions. Generally, the climates that require dehumidification are mainly (1) and (3). For high temperature and high humidity areas, it is recommended to use air conditioners to lower the temperature during the dehumidification process in cooling mode; for low temperature and high humidity areas, it is recommended to use air conditioners with independent dehumidification mode or explosion-proof dehumidifiers.

Six Small Steps for Maintaining and Servicing Constant Temperature and Humidity Machines

Oct 27,2018

Many manufacturing enterprises now require production environments to maintain certain humidity or temperature levels. This is especially true in agricultural production and the manufacturing of many electronic components, where environmental control is crucial. Temperature and humidity are undoubtedly two extremely important indicators of the production environment. To effectively control humidity and temperature, constant temperature and humidity machines must be used. However, like any equipment, they cannot be used for extended periods without maintenance. The maintenance of constant temperature and humidity machines is therefore essential. Today, I will discuss the key points of maintaining these machines and how to carry out the maintenance. 1. **Cleaning and Maintenance of the Constant Temperature and Humidity Machine's Interior and Exterior:** Before operating the constant temperature and humidity test chamber, impurities inside should be removed. The electrical room should be cleaned at least once a year, and a vacuum cleaner can be used to remove dust. The exterior of the machine should also be cleaned at least once a year, simply by wiping it down. 2. **Inspection and Maintenance of the Humidifier:** The water in the humidifier should be changed once a month to ensure water quality is clean. The humidifying water tray should also be cleaned once a month to ensure smooth water flow. 3. **Checking the Overtemperature Protector:** When the constant temperature and humidity test chamber is in operation, the overtemperature protection is set to a maximum value of 20°C to 30°C above the set point. When the temperature inside the test chamber reaches the overtemperature protection set point, the power to the heater will stop, and the overtemperature warning light will illuminate, but the fan will continue to operate. If the machine runs for a long time unattended, it is essential to check the overtemperature protector to ensure it is set correctly before operation. 4. **Cleaning Dust from the Condenser:** The condenser should be maintained regularly, at least once a month, by using a vacuum cleaner to remove dust from the condenser's heat dissipation mesh or by using high-pressure air to blow off the dust. 5. **Replacing the Wet Bulb Test Cloth:** The test cloth should be replaced when its surface is dirty or hard, or after completing temperature control before continuing with wet bulb temperature control. The test cloth should be replaced approximately every three months. When replacing, use a clean cloth to wipe the temperature measuring body, and ensure the new test cloth is cleaned before installation. 6. **Checking and Adjusting the Water Level of the Wet Bulb:** The water level in the collection tank should not be too high to prevent overflow or too low to ensure the wet bulb test cloth absorbs water properly, which affects the accuracy of the wet bulb. The water level should be maintained at about six-tenths full. The water level can be adjusted by changing the height of the collection box.
