portable air purifier.Cleaning and maintenance of constant temperature and humidity machines and their daily maintenance methods

　　The economic development speed of modern society is very fast, and people's requirements for air temperature and humidity in industrial production environments are becoming higher and higher. The application field of constant temperature and humidity environmental control equipment is also becoming wider and wider.

　　During the use process, many customers have reported that the effect of the constant temperature and humidity machine is not good, as it did not achieve the expected effect when first used, or after using it for a period of time, the effect is not as good as before, such as inaccurate temperature and humidity, and the range of temperature and humidity adjustment is fluctuating high and low.

　　Why do these problems occur? In fact, there are many reasons, most of which are not product issues, but rather the lack of attention paid to maintenance and precautions during our use. Below, we will explain the cleaning, maintenance, and daily maintenance methods of a constant temperature and humidity machine.

　　Cleaning of the appearance of a constant temperature and humidity machine

　　Wash with regular water, or use soapy water. Remember not to use corrosive liquids. And the surroundings, bottom, and ground of the box should be kept clean. The exterior of the box needs to be cleaned at least once a year to minimize dust.

　　Clean the interior of the constant temperature and humidity machine studio. Before operation, impurities inside the constant temperature and humidity machine should be removed. The distribution room should be cleaned at least once a year to avoid dust from the air from adsorbing on the surface of the machine or accessories such as condensers and evaporators. After cleaning, the body should be dried and kept dry.

　　1. Inspection and maintenance of humidifiers

　　The water storage inside the humidifier should be replaced once a month to ensure clean water quality, and the humidifier water tray should be cleaned once a month to ensure smooth water flow.

　　2. Cleaning of condenser dust

　　The condenser should be regularly maintained monthly, using a vacuum cleaner to remove the dust attached to the condenser's heat dissipation mesh or using high-pressure air to spray the dust.

　　3. Maintenance of overtemperature protectors

　　When the unit is working, the maximum set value for overtemperature protection should be increased by 20 ℃ to 30 ℃. When the temperature inside the unit rises to the set point for overtemperature protection, the power supply to the heater is stopped, and the "OverHEAT" overtemperature warning light is on, but the fan is still working. If it works for a long time and is left unattended, please make sure to check the overtemperature protector before working to see if it is set properly.

　　4. Replacement of wet ball test cloth

　　When the surface of the test cloth is unclean, becomes hard, or after the unit completes temperature control, it must be replaced before continuing to perform temperature and humidity control. The test cloth should be replaced every three months. When replacing, the temperature measuring body should be wiped with a clean cloth. When replacing a new test cloth, the corresponding area should be cleaned first.

　　5. Observation and adjustment of wet bulb water level

　　The water level of the water tank should not be too high, causing water to overflow from the water tank or causing abnormal water absorption of the wet ball test cloth, which affects the accuracy of the wet ball. The water level should be maintained at about six minutes full, and the height of the water tank can be adjusted appropriately.
