Which dehumidifier is better, how to choose a dehumidifier How to choose a dehumidifier

The function of the dehumidifier is that on the basis of the general dehumidifier, the condensation heat of the refrigerant can be taken away in whole or in part by the water-cooled or air-cooled condenser, and the remaining condensation heat is used to heat the air after passing through the evaporator, and the air outlet temperature can be adjusted by the dehumidifier.

Dehumidifiers, also known as dehumidifiers, dryers, and dehumidifiers, can generally be divided into two categories: civil dehumidifiers and industrial dehumidifiers, which belong to a part of the air-conditioned family. Typically, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water container, a casing and a controller. Here's how it works:

The humid air is drawn into the machine by the fan, and through the heat exchanger, the water molecules in the air condense into water droplets, and the treated dry air is discharged out of the machine, so that the indoor humidity is kept at a suitable relative humidity. The main production areas of global dehumidifiers are concentrated in Italy, Japan, China and other places, and China's position in the global dehumidifier market is becoming increasingly significant. In particular, industrial dehumidifiers are mostly used in medicine, hospitals, electronics, computers, and food industries; Household dehumidifiers are just starting in China's domestic market and have not yet been fully recognized by Chinese consumers.

At present, there are two common types on the market, of which the vast majority is compression dehumidifier, which is actually similar to air conditioning, and the same moist air passes through a low-temperature evaporator to condense and liquefy water to play a role in dehumidification. The general principle of the rotary dehumidifier is to absorb the water vapor in the air through a constantly rotating humidity absorption turntable, and then make the heated high-temperature dry air take away the humidity on the turntable, and then condense the high-temperature humid air at room temperature to achieve the purpose of dehumidification.

At present, the compression dehumidifier occupies the vast majority of the market share, so it is basically the same as the dehumidification principle of the air conditioner, does it mean that the use of air conditioning dehumidification is on the line, and the dehumidifier is completely unnecessary? In fact, this is not the case.

First of all, the working power of the air conditioner is obviously higher than that of the dehumidifier, and it is obviously more economical to turn on it for a long time. Secondly, unless it is a high-end air conditioner with "reheat and dehumidification", most air conditioners are dehumidifying and cooling at the same time. Although the temperature in Huangmei is usually high, it is inevitable that there will be times when it is only more than 20 degrees, and then turn on the air conditioner below, presumably the experience will be worse.

In addition, in terms of dehumidification efficiency, the main business of air conditioning is refrigeration after all, but by the way, it can also play a role in dehumidification, and the efficiency of professional dehumidification dehumidifiers is obviously incomparable. Moreover, compared with air conditioners, dehumidifiers are also lightweight and mobile, so you can move the dehumidifier to the room you need for dehumidification, which is more convenient.

There are many brands of dehumidifiers, and each brand of dehumidifier has many product series, and the technology and process of different series of dehumidifiers will be different, and the cost of different series of dehumidifiers will be different, that is to say, dehumidifier products are more diversified. Ansman products have the characteristics of high efficiency, energy saving, environmental protection, etc., not only the best products, but also the appearance of fashion and exquisite, very popular with the majority of consumers.

You have to look at the function and power of the dehumidifier, which brand is good, it is not convenient to advertise for free here.

The choice of dehumidifier mainly depends on the demand, I think you can choose some well-known small household appliance brand products.

The purchase method of dehumidifier is as follows:First, look at the amount of dehumidification. This is an important parameter that reflects the effectiveness of the use of the dehumidifier.

The larger the dehumidification amount, the better the dehumidification effect. Household dehumidifiers are generally more reasonable to allocate one liter per square meter. The humidity control range is 40%-60% (comfort mode), which is the most suitable humidity for the human body.

Second, look at the noise. Since the dehumidifier has a built-in compressor, noise should be considered. Especially for the elderly and children, as well as people who are sensitive to noise, it is important to choose products with low noise.

The CCC logo of the dehumidifier can be queried through the CCC of the dehumidifier on the National Quality Inspection and Inspection General Administration, and the main parameters and real manufacturers of the dehumidifier can be queried. In the market, dehumidifiers that have not passed CCC are not allowed to be sold.

Third, look at the brand. Household dehumidifiers are generally used as consumer durables, and consumers need the manufacturer to provide after-sales service to inspect, repair or replace parts when they fail during use. The manufacturer of well-known brand dehumidifier has a complete set of quality management system, has good product quality assurance capabilities, and its products have a certain guarantee in terms of performance and safety.

Consumers can also go to large home appliance sales malls to buy products, which can provide long-term and excellent after-sales service.

The method of selecting a dehumidifier has a focus on noiseArea size, ambient humidity, etc.

1. Pay attention to noise.

Generally speaking, the timing of compressor-type dehumidification has the sound of a compressor running, especially for early products. However, now there has been a lot of improvement, and the noise has been kept down. Like Yadu C181BHJ, due to the use of military austerity technology imported from Denmark, the noise is controlled below 48 decibels, and it will not affect the rest completely.

However, at the time of purchase, it is better to feel the practice on the spot.

Second, the size of the area.

As with anything, the purchase of a dehumidifier also needs to be tailor-made, the dehumidification force is too small will make the dehumidifier too heavy, and the dehumidification power is too strong and will consume more electricity, so don't be greedy to buy dehumidification only to return to hail can not be enough, and don't use too good dehumidifiers for small rooms, everything is bought according to demand.

3. Ambient humidity.

The dehumidification power is not always better, and if the air in the residential area is not humid enough, the dehumidifier will not be able to achieve the claimed effect. The selection is based on the humidity level of the living area and the size of the space. The more humid the dwelling area, the greater the required dehumidification capacity.

Precautions for dehumidifier purchase:

1. Types. According to the application scenario, the dehumidifier is divided into three categories in the industry - industrial type and commercial leakage type. In home life, the first thing to bear the brunt of nature is the household type dehumidifier.

Therefore, consumers should determine the application environment of the dehumidifier they are purchasing, and they cannot wear small shoes with big feet, nor can they use knives to kill chickens, and they cannot listen to the malicious guidance of unscrupulous merchants.

Second, the brand. Dehumidifiers are common and extensive in foreign home life, and there are not many domestic dehumidifier brands, but remind everyone that it is better to understand the introduction of household dehumidifiers first, so that the repair and maintenance in the future are also relatively high.

3. Functions. Temperature and humidity are the twin sisters to be controlled in the indoor environment, so temperature regulation control needs to be handled simultaneously in the production and storage environment of many industries; In addition, in the humidity content, the relative humidity of the air changes dynamically with the change of temperature, so the dehumidifier with temperature control function is also required to choose the dehumidifier according to the needs of the application environment.

Fourth, quality. Although the quality of a good brand is also guaranteed, quality assurance should still be considered when purchasing. Dehumidifiers are a mandatory commodity (CCC), which is an important criterion to ensure safe use.

The compressor-type dehumidifier has a better effect.

Now the better brand dehumidifiers are Songjing, JHS, Oujing, etc.;

In addition to the dehumidification capacity, it also depends on the functions such as sterilization and purification, and the appearance of Songjing DH02 and JHS are good.

The top comprehensive ranking of domestic brands of dehumidifiers includes Deye, Oujing, Pulishi, Gree, Midea, etc.

How the dehumidifier works:

The dehumidifier is composed of a compressor, a heat exchanger, a fan, a water container, a casing and a controller, and its dehumidification principle is condensation, which is invented according to the principle that "water vapor will condense into liquid water when it is cold". The compressor in the dehumidifier lowers the temperature of the condensate sheet, and the internal fan of the dehumidifier draws the humid air into the machine, and the moisture in the air is quickly condensed into small water droplets through the heat exchanger, and is absorbed into the water tank, and the treated dry air will be discharged out of the machine, and the humidity in the room will be kept in a suitable relative humidity after repeated circulation to achieve the effect of dehumidification. Household dehumidifiers are basically such refrigerated dehumidifiers.
