How to choose cold storage and skating rink dehumidifier？

Cold storage dehumidifier is often used in fruit and vegetable storage and vegetable air conditioning storage, high temperature storage cold storage, medical storage cold storage, ice skating rink, ski resort and other relatively low temperature environment。Among them, the humidity of pharmaceutical cold storage and food cold storage will affect the normal use and safety of food and drugs。In the relatively strict cold storage or skating rink, it is generally necessary to configure dehumidifier。

Low temperature environment dehumidifier selection: Generally common dehumidifiers are ordinary dehumidifier, low temperature dehumidifier and rotary dehumidifier (other models are omitted)。Among them, the ordinary dehumidifier is suitable for the ambient temperature of 5-38℃, the low-temperature dehumidifier is suitable for the ambient temperature of 2-8℃, and the rotary dehumidifier is suitable for the ambient temperature of -20℃ -65 ℃。Selection principle: look at the dehumidification amount and dehumidification ambient temperature。If the temperature of the cold storage and skating rink is between 2 and 12 ° C, and the humidity is 50%-70%, you can use a low-temperature dehumidifier and a rotary dehumidifier, if the relative humidity is large, try to choose a cryogenic dehumidifier。If the relative humidity is low, you can also choose a rotary dehumidifier。If the design service temperature in the cold storage is below 2 ° C and the design humidity is below 50%, it is recommended to use a rotary dehumidifier or a combination dehumidification method。

Generally involved in dehumidifier selection precautions:

        1. Select the model according to the dehumidification amount: ‌ The general dehumidification amount is calculated as follows: W=V*P*(X2-X1)/1000*1.2( kg/h)

[W= required dehumidification (kg/h), P= air density (kg/m3)1.2, V= site volume, X2= moisture content of air before dehumidification, X1= moisture content of air after dehumidification, 1.2= Safety factor (loss)】

2, according to the space and dehumidifier use place: mainly according to the volume of the use of environmental space, the size of the new air volume, the average maximum humidity value in the region (such as the maximum environmental humidity caused by the summer peak rainfall) comprehensive selection。You can also consult Sheron refrigeration to provide you with selection guidance。
