Five basic knowledge of dehumidifier
Dehumidifier also known as dehumidifier, dehumidifier, moisture-proof machine, moisture-proof machine, moisture-proof machine, just different names in different places. The following five points on the basic knowledge of dehumidifier, please browse. application knowledge of dehumidifier the dehumidifier can remove the moisture in the air and make the air dry. Moisture proof and mould proof of electronic products, optical instruments, precision equipment, high-grade clothing, leather goods, paper, seeds, tea, food and other articles. Therefore, dehumidifier is used in family, office, archives, data, library, computer room, precision instrument room, hospital, valuables warehouse, parking lot and other places. The dehumidifier is composed of compressor, heat exchanger, fan, water container, casing and controller. Its working principle is: the wet air is pumped into the unit by the fan, condensed into water by the heat exchanger, and the dry air is discharged from the machine. The air circulation can reduce the indoor humidity and turn the gaseous water into liquid State water, discharged outdoor. The heat exchanger of dehumidifier is the key part of dehumidifier, which is related to the performance and efficiency of the machine. There are two kinds of heat exchanger: single row heat exchanger and finned heat exchanger. Fin type has better performance, higher efficiency and longer service life than single row type, but its cost is more expensive. the single row heat exchanger is made of aluminum tube. The aluminum tube is exposed, and the water droplets can not stay on the aluminum pipe, and it will drop into the water tank quickly. Therefore, when the machine is started, it is easy to cause the illusion of "fast water outlet and good dehumidification". However, as soon as the machine stops running, the dripping water stops quickly. the fin type heat exchanger is made of aluminum sheet and copper tube connection. The contact surface of aluminum sheet is large, and the water drops will not start to drip until it is full of aluminum sheet. Therefore, it is easy to cause "slow water outflow" when starting upBut after the machine is shut down, the drip will still last for a period of time. The automatic defrosting device of dehumidifier can be controlled by computer or by machine: aComputer controlled automatic defrosting device: it adopts advanced computer control technology. It can accurately sense the defrosting temperature to ensure that the machine can operate normally in the environment as low as 5 ℃. It is the most advanced and reliable automatic defrosting device, which makes the dehumidifier have the "all-weather" working ability. Mechanical temperature control defrosting device: the temperature controller with metal memory piece can not accurately control the defrosting temperature, so the defrosting performance is not stable, and the defrosting device is not accurate and reliable. The main function of air conditioner is refrigeration and heating. The air conditioner with independent dehumidification function can dehumidify, but the dehumidification capacity is small, the dehumidification is slow, and the more dehumidification, the colder the dehumidification. In addition, since the air conditioner is fixed, it can only be dehumidified in a small area, more importantly, when the air conditioner is alone The vertical dehumidifier needs to increase the load several times, which not only consumes a lot of electricity, but also damages the compressor and shortens the life of the machine. Therefore, the air conditioner is not suitable to replace the dehumidifier.
