Dehumidifier dehumidification capacity trap, you hit it-

Industry  Dehumidifier_CFT Series

With the rise of dehumidifier, a new household appliance, more and more families and companies will choose to buy a dehumidifier to spend the rainy season safely. The dehumidifier has solved the problems of indoor excessive humidity, dry clothes, mildew, health problems and mildew caused by excessive humidity brought by humid weather

Nowadays, Dehumidifier has become an indispensable appliance for families and companies in the southern monsoon climate zone. With the increasing demand for Dehumidifier, there are more and more products on the market. How to select the most suitable Dehumidifier among many models has become the most concerned problem for many consumers

One of the most intuitive and simple criteria for the classification of Dehumidifier types is the amount of dehumidification. This is also the most important reference basis for Volkswagen to select Dehumidifier. However, in the face of complicated models, consumers will find that each Dehumidifier brand has its own statement of dehumidification capacity: "maximum dehumidification capacity", "daily maximum dehumidification capacity", "daily maximum dehumidification capacity", "hourly maximum dehumidification capacity", "nominal dehumidification capacity", "standard dehumidification capacity", etc

It is pointed out in the national mandatory standard (GB/T19411-2003) for Dehumidifier that the measured dehumidification volume is the real standard dehumidification volume under the "26 working conditions" (27 ℃/60% RH), that is, the water output measured in a sealed environment with a temperature of 27 ℃ and a humidity of 60% for one hour. The standard unit is Kg/h or L/h

At present, the mainstream labeled working conditions in the Dehumidifier industry include "three eight working conditions" in addition to "two six working conditions", which is the European standard, that is, the 24-hour water output measured in a sealed environment with a temperature of 30 ℃ and a humidity of 80%, and the standard unit is Kg/D or L/D After popularizing the explanation of the working conditions, consumers must make sure that comparing the dehumidification capacity under different working conditions does not have any reference value when choosing. For example, the dehumidification amount measured by the same machine under the "26 working conditions" will definitely be smaller than the dehumidification amount measured under the "38 working conditions". To summarize, the higher the humidity, the greater the dehumidification value tested in environments with higher temperatures Below, we will explain the two misconceptions about the maximum dehumidification capacity one by one

1“ ×× Maximum daily dehumidification capacity of Dehumidifier ×× Explanation: First of all, the dehumidification amount under unspecified operating conditions cannot be used as the correct reference value. In order to exaggerate the dehumidification capacity of the Dehumidifier, some businesses will test it under the condition that the humidity and temperature are far higher than the national standards, such as 100% humidity and 35 ℃ temperature, thus gaining the advantage of publicity Often, the dehumidification amount measured in this way will be much higher than the actual dehumidification amount used by consumers, reducing their expectations. And the compressor has a certain operating range, such as 5-38 ℃, and if the temperature is too high, it cannot work; The Dehumidifier also has a certain degree of load on the environmental humidity. If it is too high, the machine will be overloaded. Therefore, the dehumidification capacity measured under the excessive temperature and humidity has no practical use value in operation

2. Calculation formula for network dehumidification capacity: W=V ×ρ× (X2-X1) ÷ 1000 × 1.2=* * kg/h W=required dehumidification amount (kg/h), V=site volume ρ= Density of air (kg/m3), X2=moisture content of air before dehumidification, X1=moisture content of air after dehumidification, 1.2=Factor of safety (loss)

Explain: do you understand this complex calculation method? It doesn't matter if you don't understand it, because it's not a standard measurement method for dehumidification It should be noted that dehumidification is measured, not calculated. The dehumidification capacity of the Dehumidifier can only be measured under standard working conditions, not simply calculated by a pile of figures, because it may be the performance of the compressor and fan, the size of the area of the two devices, or even the size of the air outlet and air inlet that affect the dehumidification capacity of the Dehumidifier. The design of the overall body of the Dehumidifier and the selection of accessories are all factors that determine the dehumidification capacity of the Dehumidifier, and these are by no means the addition, subtraction, multiplication and division of some figures

The above is a standard for the selection of dehumidification capacity of Dehumidifier. In short, the dehumidification capacity of all Dehumidifier must be marked with the working condition. When comparing the dehumidification capacity, it must be under the same working condition. Do not compare and purchase based on the dehumidification capacity value advertised by the merchants
