Equipment Introduction

  • The heat pump installation modular education system is an education system that acquires facility composition capabilities by modularizing and installing parts of cold and hot heat source devices such as steam compression refrigeration, ice heat storage facilities, GHP, EHP, and system air conditioners.

  • This training system organizes a steam-compressed refrigeration cycle to understand changes in the system due to the conversion of heating and cooling through the operation of four-way valves as well as the installation practice of the refrigeration system and various basic refrigeration sequences.

Education Contents

01. Practicing to configurate circuit using contact point "c" of Ry device.

02. Practicing to configurate circuit using contact point "a","b" of magnet contactor(MC)

03. Practicing to configurate self-holding circuit for priority STOP of standard refrigeration system.

04. Practicing to configurate circuit for low temperature control using a temperature switch.

05. Practicing temp configuration of temperature switch

06. Practicing pressure configuration of pressure switch

07. Configuration circuit reversing refrigerant flow direction for "heat pump refrigeration system" and operation.

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.
