Second, cooling system
1) Use of French "Taikang" all enclosed refrigerating compressor set, each unit have to undergo a European "Taikang" computer network to monitor and there are security coded item by item is available through a computer search the Internet
2) refrigeration compressor: To ensure the chamber of the cooling rate and up to the minimum temperature requirements, to connect the container for evaporating condenser, evaporative condenser functions to low-voltage loop evaporator condenser as a high-pressure cycle used
3) The cooling system design should be energy-conditioning technology, an effective approach both to ensure the normal operation of the refrigeration unit can right under refrigeration system energy consumption and cooling capacity for effective regulation, so that refrigeration system operating costs and the failure rate down to a more state of the economy.
4) The cooling-assisted parts: air-cooled condenser coil, multi-stage evaporator fins, the main refrigeration parts and control devices are all imported originals, such as: the United States, "Danfoss" thermal expansion valve, the United States, "Ai high" dry filters; Italy "Cass properly" electromagnetic valve;
5) Refrigerant: the use of refrigerant R502 (low cycle)
6) Cooling method: air-cooled
Third, measurement and control system
1) This device uses the Japanese "Fuji" temperature control device, temperature accuracy of ± 0.1 ℃ (display range)
2) with PID self-tuning function, fuzzy control, multi-point alarm function, parameter shielding the user to adjust features, slope / thermal insulation function
3) sensor for the A-Pt100 platinum resistance sensor, high precision, accuracy
4, electrical control system
1) The electrical control part of the adoption of French "Schneider" AC contactor, thermal relays, reliable quality
2) Solid State Relays for "huajing" brand
3) Other components are well-known brand "Delixi"
4) The electrical circuit layout and design, simple operation
5) The box on the right for the electrical control cabinet, easy maintenance inspection
