From 0:00 on July 11 to 24:00 on July 11, there were 9 newly confirmed cases of COVID-19 in Yunnan Province (2 cases were confirmed cases of asymptomatic infection on July 9), and 3 newly confirmed cases of COVID-19 imported from abroad.

The epidemic has not been completely resolved so far, and it is unknown when this global disaster will end. COVID-19 test reagent and COVID-19 vaccine are still in short supply. The relative humidity in the production and assembly workshop of COVID-19 test reagent must be lower than 30%, or even 20%. In this case, ordinary cooling dehumidifiers are difficult to meet the requirements, and it is recommended to use Anshiman rotary dehumidifiers to solve the humidity problem.

When the processing space requires a temperature of 20 ℃ and a relative humidity below 40%, a rotary dehumidifier needs to be selected. The core wheel part is made of silicone or composite molecular sieve, which has strong moisture absorption ability. The impeller is divided into a 3/4 dehumidification zone and a 1/4 regeneration zone. The regeneration zone uses electric heating or steam or hot water to heat the air to 80-140 ℃ for dehydration treatment, so that the impeller can continue to recover its strong moisture absorption ability, and its service life can often reach up to 8 years.

The energy-saving mode operation of the steam system of the rotary dehumidifier: The most unfavorable environment for the operation of the dehumidifier is the rainy season every year, where the temperature is high and the relative humidity in the air is close to 100%. At this time, the rotary dehumidifier is operating at full load, and the steam supply is almost full load. The regeneration heating coil is generally at 130 ℃~140 ℃, but in winter, the outdoor temperature is mostly in a dry and cold state. At this time, the dehumidifier does not need to reach a full load state, and the corresponding regeneration heating temperature can be appropriately reduced. At this time, the steam consumption can be appropriately reduced.

The air temperature, humidity, or dew point temperature at the outlet of the rotary dehumidifier unit depends on the control of the temperature, humidity, and regeneration energy of the imported air; When the outlet humidity reaches the set value, the regeneration temperature needs to be reduced to save energy consumption; Similarly, the temperature controller is used to control the ice water flow rate of the front and rear air conditioning boxes to achieve energy-saving effects; And configure touch screens and monitoring software according to user needs.
