ZK-HWSY walk-in constant temperature and humidity laboratory

4、 Control system:

1. Adopting fully imported high-precision digital temperature and humidity control instruments, P.I.D high-precision control, to prevent long-term unstable operation;

2. Humidity is controlled through intuitive display, eliminating the shortcomings of the original temperature and humidity comparison; Accuracy: 0.1 ℃ (display range); Resolution: ± 0.1 ℃;

2. Control method: Thermal balance temperature and humidity control method, all electrical appliances use Schneider series products;

3. The temperature and humidity control adopts the P.I.D+S.S.R system for coordinated control of the same channel with automatic calculation function, which can immediately correct the temperature and humidity change conditions, making the temperature and humidity control more accurate and stable

5、 Box structure:

1. The base of the chamber is made of 8 # channel steel welded into a mesh frame, which can withstand the weight of the chamber and personnel specimens under horizontal conditions without causing unevenness or cracking on the bottom surface of the chamber, with a bearing capacity of 800kg/square meter;

2. The chamber is divided into six chamber surfaces and a double opening chamber door. The chamber material is inner stainless steel plate, the outer shell is A3 steel plate spray painted, and the insulation material is polyurethane foam insulation, which is lightweight, resistant to resistance, and has good insulation performance. The door material is made of stainless steel, and the door handle is an inner and outer opening type for testers to freely open the door from the enclosed room;

3. The air conditioning cabinet is the main body for testing the room temperature and humidity regulation cycle. The material used is SUS304 stainless steel plate, with a brushed and textured surface. The heating system, refrigeration, and temperature circulation fan temperature inlet and outlet of this laboratory are all installed in the air conditioning cabinet. The electrical control cabinet is made of A3 board spray painted, and the overall design is basically made according to the chamber body to make its appearance more coordinated with the chamber body;

6、 Protection system:

1. Overall equipment overheating;

2. Overall equipment phase loss/reverse phase;

3. Overall equipment timing;

4. Overall equipment overload, leakage, and short circuit;

5. Compressor overpressure and overcurrent;

6. Compressor delay protection;

7. Overheating protection for circulating motors;

8. Other protections include operation indicators, sound and light alarms, etc;

7、 Equipment usage conditions:

1. Environmental temperature: 5 ℃ to+28 ℃ (average temperature within 24 hours ≤ 28 ℃)

2. Environmental humidity: ≤ 85% R.H

3. The operating environment requires good indoor ventilation, and no objects should be placed 100 centimeters in front, back, left, and right of the machine;

Service commitment: Free home delivery. After the installation and debugging of the equipment is completed, relevant technical personnel will receive free operation training at the user's site, with no limit on the number of people.
