Embodiment Construction
[0014] See attached Figure 1-4 As shown, a simple interactive device for demonstrating the principle of a heat pump includes a platform 1 and a heat pump device 2 arranged on the platform 1. The heat pump device 2 includes a compressor 2-1 and an air outlet pipe 2 connected in sequence. -2, expansion valve 2-3, liquid reservoir 2-4 and air return pipe 2-5, pressure gauge 2-6 and temperature gauge 2 are respectively provided on the air outlet pipe 2-2 and air return pipe 2-5 -7. The compressor 2-1 is a hand-operated compressor, and the liquid accumulator 2-4 is filled with refrigerant.
[0015] For further optimization, the hand-operated compressor includes a cylinder 2-9 mounted on a fixed seat 2-8, inside the cylinder 2-9 is provided with a screw compression blade 2-10, and the rotating shaft One end of 2-11 links to each other with cylinder body 2-9 internal spiral compression paddle 2-10, and the other end is connected with the handwheel 2-12 that is positioned at the out...

The invention relates to technical field of science popularization education, in particular to a simple interactive device for demonstrating a principle of a heat pump. The simple interactive device for demonstrating the principle of the heat pump comprises a table body and a heat pump device which is arranged on the table body; the heat pump device comprises a compressor, an air outlet pipe, an expansion valve, a liquid storage device and an air return pipe which are connected in sequence; a pressure gauge and a thermometer are respectively arranged on each of the air outlet pipe and the air return pipe; the compressor is hand-operated; the liquid storage device is filled with a refrigerant. According to the simple interactive device for demonstrating the principle of the heat pump, the compressor is driven to operate through a hand-operated wheel; the refrigerant in a system circulates under the operating of the compressor; the transfer of heat can be sensed by an audience by touching a touching spiral structure on the air outlet pipe and the air return pipe or observing the thermometer on the air outlet pipe and the air return pipe; the working principle of the heat pump can be learned in an interacting process of the device.
Description
technical field [0001] The invention relates to the technical field of popular science education, in particular to a simple interactive device for demonstrating the principle of a heat pump. Background technique [0002] Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but not from a low-temperature object to a high-temperature object. A heat pump can absorb heat from a heat source, and then put it into a high-temperature heat source; for most teenagers, it is difficult to understand the working principle of a heat pump, which requires some demonstration devices to explain this process in a simple and clear way; the current heat pump demonstration device Generally, an external power supply is used for power supply, and the demonstration device is too complicated and unsafe. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a safe and reliable...
