Typically, a room about 10 square meters, can be 300W cooling capacity of the dehumidifier. But consumers in the purchase should take into account the actual situation of the use of space, such as the problem of the pattern, the openness, the sun's intensity, ventilation, space, the number of other personnel, such as communicating with other places together, or intense sun exposure space should be appropriate to buy a large amount of refrigerant dehumidifier. 2. Select brand dehumidifiers general as consumer durables, in the event of failure during use require manufacturers to provide consumer service, its inspection, repair or replacement of parts. Well-known brand manufacturers dehumidifier has a set of sound quality management system, with a better product quality assurance capabilities, and its products in the performance, safety aspects must be protected. 3, to determine the user program dehumidifier, generally divided improve the type and solve two kinds, household use are generally improving-based, commercial and industrial users, are generally resolved type; the brand's plan, consumers need to know whether the brand's plan to achieve your desired humidity production and management, it is very important. 4, understand the product dehumidifiers are household, commercial, industrial, custom-like, which consists of: housing, compressor, condenser, evaporator, blower, control systems and other accessories composition, performance products is the main core compressor and equipment capacity dehumidification system, the quality of the product is mainly control system as the core fans. Design Considerations moisture load calculation dehumidification system is very important in the design work to understand the magnitude of the load and source, in order to effectively remove it, sometimes different. Engineers have different results on the same space of the moisture load, because the different assumptions made in the calculation process. Finalizing the design, represents the consensus of manufacturers, system designers and owners. Key considerations ◆ external environmental conditions must be considered the maximum summer conditions and winter conditions the minimum. ASHRAE provides many standard design data. ◆ internal conditions namely, the process conditions required. Different application areas have different requirements, moisture conditions must be absolute humidity (grams of water vapor / kg dry air) to represent. ◆ After the external conditions determine the source of the moisture, moisture can begin to calculate the size of the load, a total of seven main sources: the walls, floor and ceiling infiltrated. By human breath and sweat to produce water vapor. By moisture from the product packaging. By a wet surface from. Produced by combustion of moisture. From windows and doors, holes are infiltrated. With fresh air ventilation system to enter. Each moisture source must be calculated carefully. Particular process moisture load. The calculation of moisture storage purposes is the simplest one, in general, from the main source of moisture penetration. The main basis for calculating ventilation rate.
