MR051R Compression Refrigeration Trainer Didactic Equipment Vocational Training Air Conditioner Trainer 1. Equipment introduction 1.1 Overview Compression refrigeration trainer is a device used to study the principle of compressor refrigeration. The device mainly includes four parts: compressor, evaporator, condenser and four throttling devices. The trainer includes a variety of sensors and can transmit data to a touch display. By processing these sensor readings, the relationship between throttling flow and cooling capacity can be studied. 1.2 Features (1) The compression refrigeration trainer adopts an aluminum frame structure, which is simple, sturdy and reliable. It is also equipped with 4 movable casters, which greatly facilitates users' mobile use. (2) The compression refrigeration trainer adopts a safe electrical layout and is grounded safely and reliably. (3) The compression refrigeration trainer adopts a modular design, and each unit can operate independently, greatly increasing the type and quantity of experiments. (4) The compression refrigeration trainer uses safe and environmentally friendly refrigerant R513A. (5) The compression refrigeration trainer is equipped with a port that can communicate with a PC, which can realize data collection and chart analysis of the equipment. 2.
