Split Air Conditioner Test Rig

The Split Air Conditioner Test Rig is a laboratory training system developed to provide students with hands-on knowledge of the construction, working, operation, and performance of a modern split air-conditioning system.

Manufactured by Micro Technologies, the trainer combines a functional split air conditioner with dedicated measurement and demonstration arrangements so that students can relate theoretical refrigeration concepts to the operation of actual air-conditioning equipment.

The system helps learners understand the layout and process flow of a split air conditioner, including the relationship between the compressor, condenser, expansion device, evaporator, refrigerant circuit, indoor unit, outdoor refrigeration components, controls, and measuring instruments.

During practical operation, students can observe pressures and temperatures at important points in the refrigeration cycle. These observations help explain the changes that occur as refrigerant passes through compression, condensation, expansion, and evaporation.

The trainer is particularly useful for studying the vapour compression refrigeration cycle as applied to residential and commercial split air-conditioning systems. Students can identify the high-pressure and low-pressure sections and understand the function of each major refrigeration component.

A dedicated instrumentation arrangement allows operating conditions to be monitored while the system is running. Pressure gauges provide practical observation of refrigerant-side conditions, while temperature measurement provisions help students understand thermal changes across different sections of the system.

The trainer also provides practical exposure to remote-control operation. Students can study basic operating modes and understand how user commands are applied to an air-conditioning system.

Its open demonstration layout improves component visibility and provides convenient access for instructors during lectures, demonstrations, practical sessions, troubleshooting exercises, and technical training.

The Split Air Conditioner Test Rig is particularly suitable for engineering colleges, polytechnic institutes, ITIs, universities, HVAC training institutes, vocational centers, skill-development institutes, and refrigeration & air conditioning laboratories.

Main Components

Split AC Indoor Unit

The indoor unit demonstrates the evaporator and air circulation section of a split air-conditioning system. It allows students to understand how room air is cooled and circulated.

Compressor

The compressor circulates refrigerant and raises its pressure and temperature before the refrigerant enters the condenser.

Condenser

The condenser rejects heat absorbed by the refrigeration system and converts high-pressure refrigerant vapour into liquid.

Expansion Device

The expansion device reduces refrigerant pressure before it enters the evaporator and controls refrigerant flow through the cooling circuit.

Evaporator

The evaporator absorbs heat from the air, producing the cooling effect required for air conditioning.

Pressure Measurement

Pressure gauges enable students to observe operating conditions on relevant sections of the refrigeration circuit.

Temperature Measurement

Temperature measurement provisions enable analysis of thermal conditions at important locations in the air-conditioning system.

Remote Control

A remote-control arrangement enables students to operate the split AC and understand basic user-control functions.

Working Principle

The Split Air Conditioner Test Rig operates using the vapour compression refrigeration cycle.

The basic process consists of:

1. Compression: Refrigerant vapour is compressed to a high pressure and temperature.
2. Condensation: The refrigerant rejects heat in the condenser and changes toward the liquid state.
3. Expansion: The expansion device reduces refrigerant pressure.
4. Evaporation: Refrigerant absorbs heat from room air in the evaporator.
5. Air Circulation: The indoor fan circulates cooled air into the conditioned space.
6. Cycle Continuation: Refrigerant returns to the compressor and the process repeats.

This practical cycle enables students to understand how a conventional split air conditioner removes heat from indoor air.

Pressure & Temperature Study

An important educational function of the trainer is the observation of refrigeration pressures and temperatures.

Students can investigate:

• Compressor suction conditions
• Compressor discharge conditions
• High-side pressure
• Low-side pressure
• Condenser-side temperature
• Evaporator-side temperature
• Refrigerant behaviour through the cycle
• Relationship between pressure and temperature
• Changes produced during system operation

These measurements provide practical insight into refrigeration-cycle behaviour.

Remote Control Operation

The trainer enables students to study the operation of the split air conditioner through its remote-control system.

Depending on the AC configuration, students can understand common functions such as:

• Power ON/OFF
• Temperature setting
• Cooling operation
• Fan control
• Air-flow settings
• Timer-related functions
• Operating-mode selection

Available functions depend on the supplied air-conditioner configuration.
