5. Study heating, cooling, humidification and dehumidification processes
5. Determine the COP

Features

5. The training equipment is built around an aluminum profile and a sheet metal frame that includes a silk screen panel with mounting components and a profile substrate for easy installation. The equipment undercarriage is equipped with casters with brake locks. Each system is fully equipped with piping and electrical connections so that it can be run at any time.
5. The parts are clearly laid out and labeled for easy identification, providing a cooling schematic and schematic for the instructional teaching. The refrigeration line is coded in red and blue colors, red for high pressure, blue for low pressure to indicate the state of the refrigerant, and a sight glass to monitor the refrigerant's cooling state at that location.
5. Refrigerant: R22 or equivalent
5. Components and systems include:

• Heating unit, cooler and dehumidifying unit. Sight glass, high and low pressure vacuum gauge, high and low voltage controller
• Instrument control panel with voltmeter, ammeter, on/off control, circuit breaker with leakage protection device, overload protection device, key start switch, operation indicator, four temperature displays, controller, fan speed controller. All necessary controls and wiring. A schematic of all part labels showing the text and graphics of the cooling circuit.
• RS485 information acquisition system: it can realize the interaction between the computer and the refrigeration system.

• The data is transmitted to the computer through the RS485 information acquisition serial port.
• The transmitted data includes voltage, current, phase angle, frequency, power, high and low pressure, time, etc.
• Numerical value.
• It also includes the system schematic diagram, which can be printed through the computer.
