1Large scale high and low temperature laboratorySpecification

1、 Control system:

1. The temperature control adopts high-precision microcomputer P.I.D control instruments imported from Fuji, Japan, with high control accuracy and good stability, effectively ensuring the fluctuation range of temperature and test operation;

2. The temperature control adopts P.I.D+S.S.R, and the system coordinates control with the same channel, which can improve the stability and service life of control components and interfaces. The touch button setting and multiple numerical screens are directly displayed, and it has the function of P.I.D automatic calculation, which can reduce the inconvenience caused by manual setting. In operation or setting, if an error occurs, a warning signal will be provided;

3. The heating system uses a finned stainless steel heater with a far-infrared nickel complex gold wire heating core;

2、 Refrigeration system:

1. Refrigeration system and compressor: In order to ensure the cooling rate and minimum temperature requirements of the test chamber, this test chamber adopts a binary cascade water-cooled refrigeration system composed of an imported German fully enclosed compressor;

2. The connecting container is an evaporative condenser, which also serves the purpose of energy transfer by transferring the thermal energy inside the working chamber through a two-stage refrigeration system, achieving the goal of high temperature. The design of refrigeration systems applies energy regulation technology, which is an effective processing method that can ensure the normal operation of refrigeration units while effectively adjusting the energy consumption and cooling capacity of the refrigeration system, reducing the operating costs and failure rates of the refrigeration system to a more economical state;

3. Refrigerant: DUPONT R22 (high temperature cycle) and R23 (low temperature cycle) are used

Auxiliary parts: Expansion valve (SPORLAN, USA), solenoid valve (CAS, Italy), filter (SPORLAN, USA), pressure controller (RANCO, USA), shock absorber hose (PACKLESS, USA), oil separator (ALCO, USA) and other refrigeration accessories are all imported

IIIBox 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 one 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 closed chamber;

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;

4、 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;

5、 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;

6、 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.
