a. Diversified structure, ultra-thin design
According to different requirements, there are two types of dehumidifiers: vertical dehumidifier and ceiling dehumidifier. Vertical units are divided into mobile and fixed. The mobile type realizes the mobile function through the universal wheel at the bottom. Once positioned, the universal wheel can be locked easily. The unit is equipped with a six meter power line and plug. The special drain pipe is in a high position, which is convenient for the user to move. The ceiling type unit can be hoisted on the ceiling board of the warehouse according to the user's requirements, without occupying the ground space, saving the warehouse area.
b. Modern modeling
The frame of the unit is made of high-strength aluminum materials popular at home and abroad, and the door panel is made of anti-corrosion materials. The shape of the unit comes from the hand of modern industrial modeling designer, with fresh streamline and beautiful appearance, which makes it harmonious and unified with the environment of tobacco warehouse.
c. Various air distribution modes
Considering the particularity of the stacking mode of the finished cigarette warehouse and the goods in the tobacco warehouse, the air supply and return mode of the vertical unit can not only adopt the return air on both sides and the top air, but also adopt the front return air, the top air or the back return air and the top air; the ceiling type unit adopts the DC supply and return air. These various air distribution modes provide effective and reasonable air distribution for the finished cigarette warehouse and tobacco warehouse, make the temperature and humidity in the warehouse evenly distributed, completely avoid the existence of dead angle of temperature and humidity, and maximize the dehumidification capacity, increase the dehumidification room of a single unit, reduce the investment cost and reduce the operation cost.
d. Adapt to high dust content environment
The selection of unit parts shall fully consider the factors of high dust content in the air in the warehouse. In addition, a special air filter shall be set at the air inlet of the unit to overcome the defect that the spacing between fins of the air heat exchanger is easy to block. At the same time, the filter shall be designed and installed on the external surface of the unit for the convenience of disassembly and cleaning by the maintenance personnel.
e. High efficiency and energy saving
The unit adopts imported scroll compressor, with high efficiency; the refrigeration system is designed by computer simulation optimization, and the professional experience of nearly 50 years of production and scientific research dehumidifier is gathered to improve the energy saving index to a new level.
f. Automatic cluster control
The dehumidifier of cigarette product warehouse and tobacco warehouse is mostly installed in a decentralized way. The unit can automatically start and stop according to the humidity, and can switch the working state manually and automatically, and can also start and stop remotely. At the same time, it has remote communication interface, which is convenient for remote or cluster control.
g. Multiple patented technologies
A number of patented technologies such as low temperature dehumidification and series dehumidification have been successfully integrated, and there are special anti air leakage and anti cold bridge technologies, which make the unit low in cold leakage rate and no condensation on the external surface of the unit; the unimpeded drainage structure makes the unit absolutely free from water leakage.
1.2 system principle
The air-cooled and temperature regulated dehumidifier adopts the mechanical freezing method to cool and dehumidify, that is, under the action of the fan, the indoor wet air flows through the evaporator after passing through the air filter and contacts with the surface of the evaporator. Because the surface temperature of the evaporator is lower than the dew point temperature of the wet air, the water vapor in the air is cooled and condensed into water drops, which are gathered in the water spray tray and discharged from the unit by the water hose. At the same time, the air The temperature and moisture content are reduced, so as to achieve the purpose of dehumidification.
The system has three functions: cooling dehumidification, temperature regulating dehumidification and temperature rising dehumidification (heat pump). When the room temperature is high, the cooling and dehumidification method can be used when the temperature needs to be reduced after dehumidification; when the room temperature is moderate, the temperature adjustment and dehumidification method can be used when the air outlet temperature has appropriate requirements; when the room temperature is low, the heating and dehumidification method can be used when the relative humidity can be reduced by heating.
a. Principle of cooling and dehumidification
During cooling and dehumidification, solenoid valve A is on, solenoid valve B is off, all three fans of outdoor air-cooled condenser are on, and the refrigeration system works. At this time, the condensation heat load of the system is all borne by the outdoor air-cooled condenser, and the indoor condenser does not bear the condensation heat load. That is, after the air is treated by the evaporator, it is not heated by the air-cooled condenser, so as to achieve the purpose of cooling and dehumidification.
b. Principle of temperature regulation and dehumidification
When regulating temperature and dehumidification, solenoid valve B is on, and solenoid valve A is off. The air temperature is adjusted by adjusting the number of opening fans of outdoor air-cooled condenser. At this time, the condensation heat load of the system is jointly borne by the outdoor air-cooled condenser and the indoor air-cooled condenser. The heat load of the indoor air-cooled condenser is used to heat the cold air out of the evaporator, make the air temperature rise, and then send it to the destination. Due to the change of the number of fans in the outdoor air-cooled condenser, the heat load of the indoor air-cooled condenser changes, that is, the equal humidity heating amount of the cold air out of the evaporator changes, resulting in the change of the air temperature, so as to achieve the purpose of temperature regulation and dehumidification.
c. Principle of temperature and dehumidification (heat pump)
During temperature and dehumidification, the solenoid valves a and B are closed, the four-way reversing valve acts, the unit operates under the condition of heat pump, and the three fans of outdoor air-cooled condenser are all opened. The condensation heat load of the system is all borne by the indoor evaporator. At this time, the outdoor air-cooled condenser is equivalent to the evaporator in the system, and the indoor evaporator is equivalent to the air-cooled condenser in the system. The indoor air-cooled condenser is short circuited. That is, the air is heated by the evaporator (actually the air-cooled condenser), so as to achieve the purpose of temperature rise and dehumidification.
