I am a student and I need to design an air conditioning system for a small space where only 1 person can sit and do his work. Here are the measurements of the space I'm required to cool using my system.

Height :- 145cm [1.45m]
Width :- 100cm [1m]
Length :- 200cm [2m]

Height * Width * Length = 2900000 cm3 [2.9 m3]

Additional Information :-
No direct sunlight coming to the compartment. Only one person inside. The temperature in the climate is 30 degrees of Celsius in most of the times. My system should bring down 3 degrees of Celsius when it switched on. Example if temperature before starting the system is 30 Celsius, it should be 27 Celsius after switching on the system and keep running the system sometime.


So please help me with this project. Could somebody give me which compressor, Condenser and evaporator best suits for this small system? Please give me the capacities of each of them which required for this project?

Hope this community will help me with my project.. This is my 1st post here. Thanks
