Control device

Programmable temperature and humidity controller South Korea TEMI880 touch screen. It can display setting parameters, time, heater, humidifier and other working status, and has the function of automatic test operation and PID parameter self-tuning. Only need to set the temperature to realize the automatic operation function of the refrigerator. The control system uses an intelligent control software system, with automatic combination of cooling, heating, humidification and other subsystems working conditions, so as to ensure high-precision control in the entire temperature and humidity range, and achieve the purpose of energy saving and consumption reduction. The perfect detection device can automatically perform detailed fault display and alarm. For example, when the test chamber is abnormal, the controller automatically displays the fault status.

Refrigeration principle

The refrigeration part is the main part of the equipment that produces the cold source, which provides the required cooling capacity for the cooling, low temperature and constant temperature of the equipment. According to the different test conditions of the equipment, the refrigeration system is automatically turned on to provide the cooling capacity for the corresponding test process.

The design of the refrigeration system uses energy adjustment technology. An effective treatment method can ensure that the energy consumption and cooling capacity of the refrigeration system can be adjusted under the normal operation of the refrigeration unit, so that the operation cost and failure of the refrigeration system The rate dropped to a more economical state.

Refrigeration system components

Compressor: The core of the refrigeration system is the compressor. In this plan, we use the French Taikang fully enclosed compressor to form a set of refrigeration system to ensure the cooling requirements of the studio.
