Description:

Refrigeration; Heating Trainer is applicable for teaching and training of major such as Refrigerating Air-Conditioner, Refrigerating Air-conditioner installation, Operation and Maintenance, Refrigerating Air-conditioner Automation and Air-Conditioning Technology & Application for Electromechanical Facilities , It adopts horizontal structure, is divided into two parts as split air-conditioner and refrigerator, refrigerating pipes are allocated gradually. Clear and direct viewing to make complicated refrigerating system structure easy to understand. Refrigerator has two structures as direct-refrigerating and wind-refrigerating for students to understand structure and working principle of refrigerator completely.On the left is the heat pump split air conditioner refrigeration system and control circuit, on the right is the directly cooling refrigeration system. Its difference from It is that it only has directly cooling refrigeration system and control circuit, without wind cooling refrigerator, so it is smaller than before, other features (no defrost circuit ) are as same as it.Functions For experiments, in the control circuits of refrigeration and heating systems of refrigerator and air-conditioner, we make 24 common faults, and in a same time, we make 2 Detection boards, on the control panel, we provide pressure meters, voltmeters and ammeters. The students can use all these things to learn to detect where the faults are, which improves their capabilities in problem solution greatly.Testing modes

1, faults setting, students write to answer questions;

2, PC faults setting, students use answering devices to answer questions;

3, PC faults setting, students use PC to answer questions.

A school can select a testing mode according to actual conditions.
