Description

The bench CRM005 is delivered complete, instrumented with technical handbook and lab exercises. It is based on a split system air conditioning of a widely brand on the market with an output of 2,5kW. Students will initially be familiar with the system and discover the different components. They can then switch it on and check that the operating parameters are correct. When the system is operating at its rated speed, they will have then to use the instrumentation at their disposal to conduct the surveys enabling them to complete assessment of the installation and trace the refrigerating cycle. They can also calculate the powers involved and see the energy efficiency of the system.

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminium structure on feet gives it great robustness as well as great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive

1. Split system Air conditioning with variable power production (inverter) and reversibility (heating or cooling).Power : 2.5KW. Refrigerant fluid used: R32

2. Collection tank for the water (condensation)

3. LP pressure sensor with display of the measure on the touch screen

4. HP pressure sensor with display of the measure on the touch screen

5. Temperature measurements at the characteristic points of the circuit by fixed probes thermocouple type and display of the measures on the touch screen (12 measuring points)

6. Measurement of the electrical power used by the system and display of the measures on the touch screen
7. Measurement of refrigerant flow rate with float flowmeter with magnetic transmission (7.5 to 60kg/h). The flow rate is measured only when the system operates in air conditioning mode (cooling mode).

8. The bench is supplied with portable measuring devices allowing students to get into the real case of a climate engineering technician (direct measurement on the system).
-a portable thermometer
-a propeller anemometer
-a thermo hygrometer

9. The bench is equipped with an electrical box conforming to the machine directive for the safety of persons. It is equipped with a pad lockable power disconnect switch, a punch-type emergency stop button, a GFCI with 30mA protection, a grounding of all elements and a 7 "colour touch screen
