1. Product overview

This product cont--ns technologies such as refrigeration, thermodynamics, heat transfer, and electrical control. It is m--nly composed of two parts: heat pump -type household --r -conditioning system and --r source heat pump system. Install the condenser, evaporator, throwing device, compressor, control circuit, etc. on the aluminum alloy guide track tr--ning platform, forming a typical refrigeration device. Run, truly present the work process of the refrigeration device, through the installation, pressure preservation, leakage, vacuum, electrical connection, fluoride, system debugging and working conditions of the refrigeration system to complete the modern refrigeration and --r conditioning system for students Equipment installation, debugging and m--ntenance skills tr--ning.

1. The composition and characteristics of the tr--ning device

1. The running medium of the device is the CO2-water system.

2. Equipment framework: Long × width × height 3700 × 2000 × 3700mm The whole machine uses steel installation framework (two layers of design, one layer of plane is convenient to operate, rep--r, enter and exit, the second floor has a safe diagonal ladder, with guardr--ls, non -slip, non -slip, non -slip Labor), anti -rust red dan -primer, spray p--nt treatment.

3. Absorbing tower body: The m--n body imports hard glass φ120 × 10-2000 mm; the upper exit section, st--nless steel φ120 × 300 mm; lower entrance section, st--nless steel 200 × 500 mm; And liquid distributor. Untitting tower body: The m--n body imported hard glass φ120 × 10-2000 mm; the introduction of organic glass φ120 × 500 mm in the upper exit section; st--nless steel φ200 mm of st--nless steel at the lower entrance section; And liquid distributor. CO2 steel cylinder.

4. Mechanical and equipment configuration: absorb and analyze the tower body, --r buffer tank, absorbing liquid storage tank, parsing liquid storage tank, affiliated pipe and valve.

5. Power conveying equipment: high -efficiency and low noise vortex fans, st--nless steel centrifugal pumps, electromagnetic --r pumps.

6. Detection configuration: absorbing the flow control of the liquid, analyzing the flow control of the liquid, and the detection and control of the --r flow of the fan; the CO2 flow detection, the absorption and detection temperature detection. Traffic detection: automatic detection and locally detection redundant settings.

7. Local intelligent instrumentation electrical console: Steel spraying plastic internal leakage protection --r switch, current -type leakage protector fully considers personal safety protection; Convenient control; installation with differential indicators, switching power supply, contactor, solid -state relay, self -lock switch, plastic copper wire, rubber sleeve, shielding wire, wire groove, etc. The device can be independently measured and controlled by the on -site industrial control operation table by the intelligent instrument + industrial control configuration software with the RS485 communication bus, and the tr--ning items are completed on the spot. At the same time, there is a DCS signal interface. It can also be controlled by connecting the DCS control system.

8. Analysis instrument: CO2 Online concentration analyzer (self -provided)
