Digital vortex multi-connected air conditioner refrigerating system teaching training station

Abstract

The invention discloses a digital vortex multi-connected air conditioner refrigerating system teaching training station, which consist of a digital vortex multi-connected air conditioning unit and a refrigerating system operation and control training station. The digital vortex multi-connected air conditioning unit comprises a refrigerating system and an electric control system. The refrigeratingsystem consists of a digital vortex compressor, a fixed frequency compressor, a main four-way valve, an auxiliary four-way valve, various control electromagnetic valves, a condenser, a throttling part and a multi-connected indoor unit. The electric control system comprises a sensor, a main control board, a digital vortex controller and a plurality of electric appliance actuating mechanisms. The front side of the refrigerating system operation and control training station is printed with a refrigerating system pipeline structure schematic diagram and is provided with a thermal parameter instrument and an electric quantity parameter instrument which are used for displaying real-time parameter values. By two modes of simulation and real operation, design functions of comprehensive learning training, experiments and the like such as operation mechanism learning, signal measurement, fault setting and diagnosis, signal acquisition and real-time demonstration, performance tracking research and the like are realized.

Description

technical field [0001] The invention relates to the field of teaching appliances, and more specifically relates to a digital scroll multi-connected air conditioner refrigeration system teaching and training platform. Background technique [0002] The scroll multi-connected air conditioner uses digital control technology and is widely used because of its wide energy adjustment range and superior oil return. The core component of the scroll compressor is composed of two involute scroll wraps (moving and static scrolls) with the same shape but staggered by 180° relative to each other, forming multiple crescent-shaped air cavities. When one of the rolls rotates around the other, the shape and size of the crescent-shaped air cavity is constantly changing, and its closed volume is gradually transferred to the center of the fixed roll and shrinks continuously, and the gas is continuously compressed and the pressure rises. The digital scroll compressor uses the axial flexibility te...

Problems solved by technology

However, for the teaching of the working principle of the digital scroll air conditioner and the detection and maintenance of common faults, it lacks intuition and demonstration functions, and the test bench needs to add various control and adjustment equipment, data acquisition computers, and requires investment. A large amount of funds cannot meet the needs of professional teaching practice
