INVERTER AIR CONDITION AND REFRIGERATOR COMPREHENSIVE TRAINING DEVICE
PRODUCT INTRODUCTION
XK-ZLZR2 mainly introduce the system structure and working principle of frequency conversion air conditioner and indirect cooling, direct cooling refrigerator; The understanding and detection method of the frequency conversion air conditioner components; The electrical control principle of frequency conversion air conditioner and indirect cooling, direct cooling refrigerator. Trainer with intelligent fault assessment function
XK-ZLZR2 is composed by system of frequency conversion air conditioner and indirect cooling, direct cooling refrigerator. The electrical control system and pipeline system are separate, and all show outside, easy for user to observe and learn. Variable frequency air conditioner control panel adopts transparent organic glass to cover, more safety.
The electrical control system includes leakage protector, voltmeter, ammeter, 8-way temperature meter and electrical principle diagram with measurement point; pipeline system is composed by compressor, condenser, evaporator, lens, high-pressure gage, low-pressure gage.
The training bench adopts spraying plastics structure. The desktop is fireproofing, waterproofing, wear-resisting high density board, with strong structure. Bench with 4 universal wheels, easy for movement
