Working Principle:
The display cabinet constant humidity machine effectively combines dehumidification and humidification functions into one, mainly consisting of an evaporation section, a humidification section, a condensation section, and a circulating fan section. The method of sending back air and sending back air in front, through computer programming, ensures the effective operation of each working section to meet the requirements of environmental humidity. The humidification method of the constant humidity machine is to use ultrasonic atomization humidification, which produces pure humid air through ultrasonic atomization. A precise and reliable constant humidity control system with a relative humidity of ± 5% can be achieved.
Dehumidification principle: The air is filtered and sucked in by the fan. It is first cooled by the evaporator. As the temperature drops below the dew point temperature of the air, the water vapor contained in it will condense and be discharged from the drip tray at the bottom of the evaporator. The dehumidified cold air is heated by the condenser, which can prevent the temperature inside the cabinet from decreasing and also reduce the condensation pressure of the refrigeration machine, thereby improving the refrigeration efficiency.
Humidification principle: When the humidity inside the cabinet is lower than the set humidity, the equipment automatically starts the humidification state, the water pump and ultrasonic atomizer start working, and the humidified air is sent into the cabinet by the fan. When the humidity reaches the set value, the humidification automatically stops.
Product Features:
The display cabinet specific constant humidity machine is mainly developed for products that require constant temperature and humidity in small spaces. It adopts an integrated design and does not have an outdoor unit, saving space for installing an outdoor unit. The main components used in this product are all imported from internationally renowned brands. The unit is equipped with various automatic protections. Compared with other similar products, it has the characteristics of high efficiency, compact and lightweight structure, smooth operation, easy operation, beautiful appearance, high wind pressure, long service life, and low noise. Mainly used in museum cultural relics display cabinets and small storage rooms.
1) Structural Design
The display cabinet constant humidity machine adopts a steel frame structure, which has a tight steel profile structure, strong corrosion resistance, and is equipped with an anti cold bridge device, effectively preventing the occurrence of "condensation" phenomenon. Featuring a flat and seamless detachable panel. After opening, the device can be maintained and serviced.
2) Function
This machine has two functions: humidification and dehumidification. When the humidity is relatively high, the dehumidification function is used, and when the humidity is low, the humidification function is used. This can meet the requirements of humidity and achieve energy-saving effects. The unit is equipped with a standard G4 filter screen, which has good filtering effect.
The defrosting method adopts an optimized structural device, which uses a unique defrosting method while ensuring the stable operation of the refrigeration system, without affecting the system operation.
The refrigerant used is R134a refrigerant that meets the requirements of the national plan to phase out CFCs, which is beneficial for environmental protection.
4) Accessories
The compressor and main components are made of products from international brands such as Panasonic and Emerson. Through scientific and rational optimization design of the refrigeration system, they ensure normal operation in different environments. Overcoming the shortcomings of insufficient dehumidification capacity and high product failure rate due to frequent unit startup of domestic models in the same industry. At the same time, it also improves the service life of the product.
The fan adopts imported centrifugal outer rotor fan, steel volute shell and blades, with high efficiency and low noise.
5) Control
The unit adopts a dedicated microcomputer LCD liquid crystal control, which can automatically start and stop according to the user's set relative humidity, with high accuracy, good reliability, beautiful appearance, and easy operation. As long as the user sets the required humidity, the equipment can operate automatically. The device also has an international standard Modbus 485 communication interface, which enables remote monitoring and fault analysis using a computer, helping you quickly and accurately predict and troubleshoot faults. It also has remote control function.
6) Protection
The unit has functions such as temperature and humidity display, fault display, etc. Equipped with overload, water shortage, water leakage, low pressure protection, etc.
The design of the constant humidity system equipment for display cabinets complies with the requirements of IEC protection level IP 44.
