CZ Series Seed Low Temperature and Low Humidity Cabinet Instruction Manual
I. Overview:
The CZ series energy-saving seed low-temperature and low-humidity storage cabinets were designed according to the research results of seed experts Hu Jin from Zhejiang University. It provides the best storage equipment for long-term storage of seeds, especially long-term storage of precious seeds.
The biggest highlight of this cabinet is constant temperature and humidity performance, and energy saving:
First, because the storage cabinet uses a full foaming process, it has excellent insulation properties and good sealing properties.
Second, the intermittent operation of the compressor and the advanced CFPID hyper-fuzzy control technology make it possible to meet the high standards of constant temperature and humidity and reduce energy consumption.
Third, the cabinet adopts a special structure and adopts a unique control mode, so that the evaporator is not easy to frost.
Fourth, the instrument will automatically defrost, and defrost without heating power.

5. Humidity fluctuation: ±5%RH
6. Cooling power: 150W~350W
7. Dehumidifying power: three times the cooling power
8. Defrosting method: automatic defrosting
9. Compressor working mode: intermittent work, including stop delay protection time is 5 minutes.
10. Power supply: AC 220V 50~60HZ
11. Running time: long-term continuous operation
12. Use environmental conditions: temperature 0~35°C, humidity ≤85%RH, air pressure 86~106Kpa, good ventilation around, no strong electromagnetic field influence, no strong vibration, no high concentration of dust and corrosion, no direct sunlight or other heat source Radial, ground level.
Third, the composition and structure of the instrument:
Storage cabinet consists of shell, insulation layer, stainless steel liner, cabinet door, top cover, studio, duct, circulation fan, heater, refrigeration system (by compressor, condenser, condensation fan, buried evaporator, capillary And connecting pipe and other components), control system, sterilization lamps and other components. The dehumidification system is served by a refrigeration system and a heater.
The control system consists of controllers, power plugs, fuses, power switches, temperature sensors, humidity sensors, and output cables and outlets.
The controller consists of three parts: the main control board, the display board and the panel. The main control board is fixed on the bottom of the top cover. The display board is close to the inside of the top cover panel. The instrument panel is glued on the outside of the top cover panel. The transparent window and display The display devices of the board are coincident, showing the Beijing time, the temperature inside the box, the humidity inside the box and various working status indicators. The panel structure is shown in Figure 1. The current working status displayed on the panel is: The measured temperature in the box at 19:18 in Beijing was 5.6°C, and the measured value in humidity was 52%RH. The panel is equipped with various operating switches.
Fourth, the operation method
1. Power on: Insert the three-pin power plug of the storage cabinet into the three-conductor power socket with a grounding wire on the wall of the lab, and close the power switch of the cabinet. Within five seconds afterwards, each digital window on the panel displays the current Beijing time, the measured temperature inside the box and the measured value of the humidity inside the box.
2. Set the parameter check:
Pressing the key, the first digit in the "inside temperature" digital display window flashes. At this time, "inside temperature" and "indoor humidity" respectively show the temperature setting value in the cabinet and the humidity display value in the cabinet. Press the key again, the flashing in the digital display window will stop and return to the running state. If you do not press the button, it will automatically return to running after ten seconds. The instrument has been set at the factory according to the usual best conditions, ie the set temperature is 5°C and the set humidity is 50% RH. Under normal circumstances users can no longer modify.
3. Parameter setting:
To modify the temperature or humidity setting, follow the procedure below:
1 Press the key, and the first digit of "Inside temperature" flashes. 2 Press the or key several times to set the tens digit of the temperature inside the box. 3 Press the key, and the single digit of "Inside temperature" flashes. 4 Press the or key several times to set the temperature in the box. 5 Press the two buttons, and then the "box humidity" ten digits flash. 6 Press the or key several times to set the ten-digit humidity in the box. 7 Press the key, and the "inside humidity" digit flashes. 8 Press the or key several times to set the humidity within the box. 9 After the setting is completed, press the key to confirm. At this point the digital display window no longer flickers, ie it returns to the operating state.
4. The time is right:
Press the "Time" button, the first digit in the "Time" window is flashing, and then press the,, keys again to adjust the time. After adjusting, press the "Time" button to confirm.
5. Sterilization: press the "sterilize" button, the sterilization lamp is on; press the "sterilize" button again, the lamp will be dark again.
V. Precautions:
1. To ensure safety, the power outlet for the instrument must have a good grounding wire.
2. The sterilization lamp is an ultraviolet lamp and must be turned off when it is not sterilized. Otherwise, the seeds will be killed.
3. Dehumidification is at the expense of energy consumption. When dehumidifying, it requires both cooling and electric heating with twice the cooling power. Therefore, the lower the humidity, the higher the energy consumption. Therefore, if it is not necessary, the humidity inside the box should not be adjusted too low.
4. When the cabinet is in use, close the door tightly to reduce air leakage. This reduces energy consumption and also reduces the number of frosts.
When the temperature in the cabinet is set below 3°C, the air in the air duct is apt to freeze. Therefore, under normal circumstances, the set temperature should not be lower than 3°C. The instrument will automatically defrost, and the temperature and humidity in the chamber will be higher than the set value during defrosting (the maximum temperature in the chamber during defrosting will not exceed 9°C). This is normal.
