Suzuki: car A/C, maruti suzuki, engine radiator

Question
QUESTION: sir, i bought a maruti suzuki 800 but the air conditioner cooling is not well i am not feeling the chillness it is likely to be superb only in night.but if it is operated in days and summer the cooling is very low what is the problem in this A/c? i also topped up the A/C gas but also in the same condition do u solve this problem
ANSWER: It's possible that the condensor in the front of the vehicle is dirty, or that in some way the free air flow over it is somehow reduced.  Does the fan work well?
The fact that the system works well in the evening when the outside air is cooler, and the rate of heat transfer is higher indicates that the capacity to transfer heat outside is somehow impaired.  Another thing that has a direct relation to cooling is engine speed.  Many vehicles have severely reduced capacity to pump heat outside due to low engine rpm at idle, and low compressor speed, as well as lower system voltage at idle.   I'm not at all familiar with the model of your vehicle, given that it's not available in my country (US).  I have noted that in many smaller vehicles, the A/C system is not of sufficient capacity.  Many of those systems while having the capacity to cool the interior somewhat, are not sufficiently powerful to require that they be turned to a lower setting to avoid overcooling the interior.  If the temp of the air coming out the vents is near 42 degrees F, 5 C, the system is working well, but is of somewhat low total capacity.

QUESTION: what is a condensor? where it is situated whether if i clean that all problem will solve?

Answer
A condensor is the "radiator" for the A/C, (the hot high pressure gas condenses into high pressure liquid in it, hence the name) that usually is located in front of the engine radiator.  They frequently get clogged with dead bugs in the spring, which is why I mentioned it.
