1. Product overview

The product design process refers to the relevant requirements of the technical document of the "Refrigeration and Air Conditioning" skill competition and the national vocational skills standard of "Refrigeration Equipment M--ntenance". Highlight the technical and skills tr--ning content such as "installation", "debugging", "m--ntenance", "design", "management", and the purpose of cultivating professional and technical talents of refrigeration and --r conditioning.

The equipment can perform skills tr--ning such as installation, commissioning, operation, detection and m--ntenance of refrigeration equipment. At the same time, the equipment follows the principles of combining tr--ning, appr--sal, and competitions. , Labor tr--ning and skills appr--sal, teaching, tr--ning, practical assessment, and skill appr--sal of the units, and can also be applied to typical carriers of the cooling and --r conditioning professional integration skills competition. Settlement of professional skills competition for refrigeration and --r conditioning technology.

2. Equipment function and structure

The design concept of the equipment is modular design, and the combined transportation of the carrier is the workbench assembly, the refrigerator refrigerator, the cold water tank, the water tank, the water heatement, the fan coil, the power box, the tr--ning electric control box, the refrigeration yuan yuan An open tr--ning platform composed of devices. The structure and component introduction of the equipment are as follows:

Working table assembly: Work desk consisting of the table legs, tablet panels, side wooden boards, mesh baffles, and universal wheels. Students can freely install refrigeration components on it. Use a universal wheel with a brake to facilitate the adjustment of the equipment.

Refrigerator refrigerator: The high -quality st--nless steel plate is used as the skeleton. After the mechanical processing is formed, the partition layer uses polyurethane foam to keep it. Install the optical tubular evaporator. The middle part of the gates is built with a three -layer heating and transparent glass, which not only meets the insulation performance requirements, but also facilitates internal viewing. The library body is connected around the library to facilitate the adjustment of the equipment. 75L volume.

1. The composition and characteristics of the comprehensive tr--ning device system of heat transfer process

Equipment m--n body: Object part: length × width × height: 3700 × 2000 × 3500mm. The whole machine uses steel installation framework (two layers of design, one layer of plane is convenient to operate, rep--r, enter and exit. Guardr--l, non -slip pattern)

1. The system's heat exchange system is: water vapor---r (dual-column tube heat exchanges); cold --r-heat --r (sleeve, column tube, plate type); water-hot --r system (￠ 159 single tube heat exchange device) Essence

2. Taking the heating device of 9 159 as the m--n body to do heat transfer tr--ning, the dual -parallel tube heat exchanger structure can be operated normally, one is a fault operation, compared with each other, and the dual -parallel tube is replaced. The heat shift can also be performed by the heat exchanger. The steam pressure and flow adjustment system of the system are required to be controlled in the shell of the system. At the same time, the system can automatically set the fault point, and the ability to tr--n students (gas blockage, water blocking).

3. Make a tube heat exchangeer into dissectionable formula. If it is not installed on the system, the teacher will expl--n the structure of the student to the student, so that students will strengthen their understanding of the structure of the heat exchanger.

4. The temperature is measured by high -precision imported patch type exquisite PT100+intelligent inspection recorder measurement. Each temperature zone is sent to the local number, the traffic detection band is delivered on the spot, and the basic principles and processes of the computer for data collection and process control. The steam source adopts industrial standard automatic steam generator. The heating pipeline adopts a pipeline flange connection, which is not only good -sealing performance, but also easy to disassemble. Display the detection control instrument on the spot: select Xiamen Yudian smart instrument (with local control RS485 communication interface).

5. Local intelligent instrumentation electrical console: Steel spraying plastic internal leakage protection --r switch, current -type leakage protector to fully consider personal safety protection; at the same time, each set of strong electricity output has knob switch control; Lights, switching power supply, contactor, solid -state relay, self -lock switch, plastic copper wire, rubber sleeve, shielding wire, aluminum alloy wire groove, etc.
