Abstract
The utility model discloses a refrigeration system demonstration platform for teaching, which is formed by communicating condensers, evaporators, a compressor and a throttle valve through pipelines, wherein the condensers and the evaporators are respectively more than one, and at least the condensers and the evaporators are manufactured by transparent materials. The pipelines can be pipelines manufactured by transparent materials. For the sake of safety, the peripheries of the evaporators and the condensers manufactured by the transparent materials are respectively equipped with a transparent anti-explosion protection chamber. The utility model can enable students to clearly observe the demonstration process of refrigeration, and provides a perfect education appliance for experimental lessons.
Description
Technical field
The utility model relates to a kind of teaching refrigeration system Demonstration table.
Background technology
At present conventional refrigeration system is a compression-type refrigeration, referring to shown in Figure 2, generally by evaporator 401, condenser 201, compressor 101 and throttling valve 301 by the road UNICOM constitute.The refrigeration system demonstration that is used to impart knowledge to students then is to utilize cold-producing medium to flow in pipeline, behind flow through respectively condenser and the evaporator, reaches the purpose of refrigeration by the conversion of gas-liquid attitude.Cold-producing medium variation of state in system is a this system most important characteristic, also is the difficult point in the teaching.In the refrigeration demonstrating system of routine, transfer conduit is generally metal tube, evaporator, condenser also are to make with metal or some opaque materials, and evaporator, condenser be refrigeration system the complicated place that changes takes place, the feature that can reflect cold-producing medium state variation in system, but because of cold-producing medium is closed in wherein, the student can't see the variation of its inside from the outside, can only lean on teacher's preach and the abstract understanding of student oneself, be difficult to be understood thoroughly by the student.
Summary of the invention
The purpose of this utility model provides a kind of refrigeration system Demonstration table of teaching intuitively.
For achieving the above object, the utility model is taked following design proposal:
A kind of teaching refrigeration system Demonstration table, by evaporator, condenser, compressor and throttling valve by the road UNICOM constitute, wherein condenser be one or more than, evaporator be one or more than, and evaporator and condenser are evaporator and the condenser that transparent material is made at least.
Described pipeline can also be the pipeline that transparent material is made.
For safety, install transparent explosive-proof protector chamber respectively additional in evaporator and condenser periphery that transparent material is made.
In refrigerant circulation line, can install the control assembly of one group of simulated condition additional.
Described control assembly can be four-way change-over valve, be installed at least a in liquid storage bottle behind the condenser or condenser and the evaporator water flowrate control valve.
Described transparent material can be glass, organic glass or nylon.
The utility model has the advantages that: can make the presentation process of student's clear view refrigeration, for laboratory provides a kind of desirable teaching aid.
Description of drawings
Fig. 1 is the utility model teaching refrigeration system Demonstration table principle of compositionality synoptic diagram.
Fig. 2 is the teaching of a prior art refrigeration system Demonstration table principle of compositionality synoptic diagram.
Below in conjunction with drawings and the specific embodiments the utility model is described in further details:
Embodiment
Consult shown in Figure 1, the utility model teaching with the refrigeration system Demonstration table by compressor 1, condenser 2, throttling valve 3 and evaporator 4 by the road UNICOM constitute.
The utility model main innovate point is: condenser and evaporator are made by transparent material; Can be glass or nylon etc.
Described pipeline can also be that transparent materials such as glass or nylon are made.
For safety, the condenser and the evaporator periphery of making at transparent material install transparent explosive- proof protector chamber 51,52 respectively additional, can be frame bodies such as clear glass, organic glass or nylon, injury observer in the time of can preventing condenser and the unexpected explosion of evaporation.
For strengthening the function of the utility model teaching with the refrigeration system Demonstration table, can be improved with refrigeration system Demonstration table structure existing teaching, in refrigerant circulation line, install additional one group can simulated condition control assembly, as in pipeline, installing the four-way change-over valve of one group of simulation heat pump operating mode additional, or behind condenser, install liquid storage bottle additional, adopt the condenser (21,22 of a plurality of parallel connections ... 2n) and evaporator (41,42 ... 4n) etc., referring to shown in Fig. 1.
Claims (6)
1, a kind of teaching refrigeration system Demonstration table, by condenser, evaporator, compressor and throttling valve by the road UNICOM constitute, it is characterized in that: wherein condenser and evaporator respectively are more than one, and condenser and evaporator are evaporator and the condenser that transparent material is made at least.
2, teaching according to claim 1 refrigeration system Demonstration table is characterized in that: the pipeline that described pipeline is also made for transparent material.
3, teaching according to claim 1 refrigeration system Demonstration table is characterized in that: the evaporator and the condenser periphery of making at transparent material install transparent explosive-proof protector chamber respectively additional.
