Air Conditioning Test Rig (Conditioning of Room Air)
Model Number: MT-401
The Air Conditioning Test Rig (Conditioning of Room Air) from Micro Technologies is an educational laboratory system designed for practical study of the vapour compression air conditioning cycle and room-air conditioning processes. The equipment enables students to observe refrigeration and air-conditioning parameters and calculate the Coefficient of Performance (COP) using the P-H diagram. It is suitable for refrigeration & air conditioning, HVAC, thermal engineering, and mechanical engineering laboratories.
Product Specification
The Air Conditioning Test Rig (Conditioning of Room Air) is a laboratory training system developed to provide students with practical understanding of refrigeration and room-air conditioning principles.
Manufactured by Micro Technologies, the equipment demonstrates the operation of a vapour compression air conditioning system and allows students to correlate theoretical refrigeration-cycle concepts with actual operating conditions.
The test rig incorporates the essential components of a vapour compression system, including a compressor, condenser, expansion device, and evaporator/cooling section. These components work together to remove heat from conditioned air and reject it to the surroundings.
During operation, low-pressure refrigerant vapour from the evaporator enters the compressor, where its pressure and temperature increase. The high-pressure refrigerant then flows to the condenser and rejects heat. After condensation, the refrigerant passes through the expansion device, where its pressure decreases before entering the evaporator to absorb heat and provide the required cooling effect.
A major educational objective of the system is to allow students to study room-air conditioning and understand how refrigeration principles are applied to maintain desired indoor conditions.
The test rig can also be used to determine the Coefficient of Performance (COP) of the air conditioning system. By taking appropriate pressure and temperature measurements and plotting or referring to refrigerant properties on a Pressure-Enthalpy (P-H) diagram, students can analyze the refrigeration cycle and calculate system performance.
This practical approach provides a better understanding of refrigerant behaviour, compressor work, refrigeration effect, heat rejection, pressure variations, and overall air-conditioning performance.
The equipment is suitable for engineering colleges, universities, polytechnic institutes, technical institutes, vocational training centers, and RAC/HVAC laboratories where practical air-conditioning experiments form an important part of the curriculum.

Operating data can be related to a Pressure-Enthalpy (P-H) diagram to understand:
- Refrigeration effect
- Compressor work
- Condenser heat rejection
- Refrigerant enthalpy changes
- Cycle performance
- COP of the system
Main Components
Compressor
The compressor draws low-pressure refrigerant vapour from the evaporator and compresses it to a higher pressure and temperature.
Condenser
The condenser rejects heat from the high-pressure refrigerant and converts refrigerant vapour into a high-pressure liquid.
Expansion Device
The expansion device reduces refrigerant pressure and regulates refrigerant flow into the evaporator.
Evaporator
The evaporator absorbs heat from the air, producing the cooling effect required for room-air conditioning.
Air Circulation Arrangement
An air circulation system enables conditioned air to move through the experimental section for practical study of air-conditioning performance.
Measurement & Control System
Suitable instrumentation and controls enable operating parameters to be monitored during experiments.

Working Principle
The Air Conditioning Test Rig operates on the vapour compression refrigeration principle.
The operating sequence consists of:
- Compression: Low-pressure refrigerant vapour is compressed to high pressure.
- Condensation: High-pressure refrigerant rejects heat in the condenser.
- Expansion: Refrigerant pressure is reduced through the expansion device.
- Evaporation: Low-pressure refrigerant absorbs heat from air in the evaporator.
- Air Conditioning: Air passing through the cooling section loses heat, producing the required conditioning effect.
- Cycle Repetition: Refrigerant returns to the compressor and the process continues.
P-H Diagram Analysis
The Pressure-Enthalpy (P-H) diagram is an important tool for evaluating refrigeration and air-conditioning cycles.
Using experimental observations, students can identify important cycle states and evaluate:
- Compressor inlet condition
- Compressor outlet condition
- Condenser outlet condition
- Evaporator inlet condition
- Refrigeration effect
- Compressor work
- Heat rejected by condenser
- Enthalpy changes
- Theoretical COP
This experiment helps connect thermodynamic theory with actual air-conditioning system performance.
Coefficient of Performance Study
The COP provides an indication of refrigeration-system performance.
For cooling applications:
COP = Refrigeration Effect / Compressor Work
By obtaining suitable operating measurements and using refrigerant properties from a P-H diagram, students can determine the performance of the air-conditioning system experimentally.
