Equipment General Introduction

The device consists of air conditioning system and double temperature cold storage system. It mainly strengthens students' comprehensive professional ability of air conditioning and cold storage system: piping design and installation, electrical wiring, working condition debugging, fault diagnosis and maintenance, and the use of refrigeration tools etc.

The system consists of two parts: electrical control system and pipeline system, The two parts are separate, The electrical control system includes:  the power supply and assessment module which with the leakage protection function, the electrical control module of Split type heat pump air conditioning, and electrical control module of double temperature cold storage. The pipeline system is divided into the heat pump air conditioner and double temperature cold storage.

The equipment has the function of intelligent fault assessment, which can be used for the student practical assessment of the electrical control system of air conditioning and double temperature cold storage.

Equipment Characters

The equipment integrates the piping system installation, leakage detection, pressure keeping, vacuum extraction, filling refrigerant, electrical control system wiring and system operation and debugging of the air conditioning and double temperature cold storage.

The equipment adopts modular design, the electrical system and pipeline system are independently separated, the electrical system sets the test terminals and output terminals, students can do the operations of electrical testing, wiring and debugging. Piping system can be used for piping design and installation training operation.

The equipment visual displays the structure and working principle of air conditioning and double temperature cold storage, which is convenient for teaching demonstration explanation and students' understanding and mastery of textbook knowledge.

The device is equipped with movable pressure gauge and an 8-way temperature survey instrument, which is used to measure the temperature and pressure value of system key points, the system can be calculated and analyzed.
