|
|
Control and protection system
|
Continuous PID control; uses SSR solid-state relays as heating actuators (safe and reliable); with a separate over-temperature protection system
|
|
Compressor
|
The core component of the refrigeration system is a fully enclosed compressor from France (Taikang), forming a refrigeration system to meet the cooling requirements of the working chamber. The refrigeration system consists of a high-pressure refrigeration cycle and a low-pressure refrigeration cycle, with the connecting container being the evaporator. The evaporator of the low-pressure cycle functions as the condenser of the high-pressure cycle
|
|
Oil separator
|
Equipped with the "Aico" ALCO oil separator from Europe and America (to ensure the compressor has sufficient refrigerating oil and avoid performance reduction of heat exchangers)
|
|
Refrigeration evaporator
|
Located in the air duct compartment at one end of the test chamber; ventilated by a blower motor for rapid heat exchange
|
|
Energy regulation measures
|
While ensuring main technical indicators, the system's refrigeration capacity is adjusted according to different cooling rates and temperature ranges. Adopts additional energy regulation measures such as evaporator temperature regulation, energy regulation, and hot air bypass energy regulation to reduce equipment energy consumption while meeting main technical indicators
|
|
Air duct system
|
Equipped with an internal circulation air supply system for high uniformity. Heaters, refrigeration evaporators, fan blades and other devices are distributed in the air duct compartment at one end of the chamber. A fan circulates internal air: air in the chamber is sucked into the air duct from the bottom, heated and refrigerated, then blown out from the top of the air duct. Air that has undergone heat exchange with samples is sucked back into the air duct for repeated circulation to achieve temperature setting requirements
