Air conditioning refrigeration technology multi function continuous training device

Abstract

The invention provides an air conditioning refrigeration technology multi function continuous training device. The device is mainly composed of a compressor, high and low pressure oil separators, an oil storage tank, a filter, a refrigerant recovery storage tank, a cooling heat exchanger, a heat regenerator, a subcooler, a vacuum pump, a capillary, a pressure controller, a multi-position two-way control valve and an electric three-position two-way valve and the like, wherein the main parts are connected through pipes. When refrigerant recovery is carried out, boiling and condensation heat of a recovered refrigerant are fully used. High and low pressure oil separators of two different structures are used, thus recovered frozen oil and frozen oil in the device are separated from each other, and the operation stability of the device is enhanced. Through the opening states of the vacuum pump, the pressure controller, the electric three-position two-way valve and a flexible hose connector with a stop valve, air conditioning refrigeration training device vacuum pumping, refrigerant filling, device emptying, refrigerant recovery storage tank replacing and vacuum pumping and other operation tasks are flexibly realized, and the purpose of refrigeration air conditioning technology continuous training is realized.

Description

technical field [0001] The invention relates to a multifunctional continuous training device for air-conditioning and refrigeration technology. It belongs to the technical field of air-conditioning and refrigeration equipment. Background technique [0002] Air-conditioning and refrigeration equipment has been widely used in all aspects of social life. How to effectively train senior technicians for air-conditioning and refrigeration equipment will play a decisive role in my country's economic development. At present, when college students learn air-conditioning and refrigeration technology, their training equipment mostly adopts commercial molding products with various scattered tools, which brings inconvenience to the management of the training room. In order to meet the teaching requirements of the students' classes, not only the training room is required to have a large space, but also the preparation time before the training is long. And because the equipment is often ...
