Equipment Introduction

  • The automatic control unit is composed of Power Module, DC 24V Power, SEL Switch, T/S, BZ, Lamp, Push Button S.W, MC, RELAY, TIMER Module, DC 24V Input, Temperature Module.

  • Changing the location of each device on the workstation should be configurable directly by the trainer, consisting of compressor module, the heat exchanger 1 module, water exchanger 2 modules, and automatic control panel, and the workstation should be made easy to move and attach each module.

  • Using eight K-types of the temperature sensor in the freezer, the temperature indicator attached to the control panel shall be displayed in real-time.

  • Temperature control and indicators shall be equipped with 032q * 8EA of k-type thermocouple wires and shall be able to measure and analyze temperature values in real-time during the operation of the equipment.

  • The pen motor of the heat exchanger 1 and 2 modules shall be subject to random adjustment of speed and everywhere in the control area shall be practicable by constructing a circuit with DC24V.

Equipment Characteristics

  • The refrigeration system expander may arbitrarily change the evaporation pressure during operation by attaching and adjusting the manual expansion valve. Based on the theoretical refrigeration cycle centered on textbooks (theoretical education), performance can be verified and compared in the actual reference refrigeration cycle by operating various variables such as condensation temperature variable (condensation pressure variable), evaporation temperature variable (evaporation pressure variable), overheating compression, wet compression, dry saturated compression, and supercooling.

  • The automatic control device allows you to experience the basic practice of various controls that must be passed on in science and engineering, including the refrigeration system, and the practice necessary for the performance and adjustment of the device. In addition, various controllers are used to experience the basic circuit configuration required for standard refrigeration cycle operation to experiment and practice real wiring configuration operation in a short time, thereby providing understanding and practical skills of automatic control circuits in complex refrigeration systems.

  • In particular, it is an educational system that can learn a sense of practice and improve adaptability to the field by installing an operation system in a heat pump-type cooling and heater used in commercial products or industrial industries using a small laboratory-level system.
