hi what factors are influences the cooling effect of airconditioning?

Question

which consumes high power for same capacity,air conditioner or refrigerator.and why?

Answer 1

The horespower per ton of refrigeration increases when the evaporator cooling temperature is lowered. Likewise the horsepower increases as the condensing temperature increases. This occurs principally because of the greater differences in pressure thru which the compressor has to work.
Because to the thermodynamics and the characteristics of refrigerants, a low temperature system will require more unit horsepower than a moderate temperature system.
If you wanted to have a refrigerator-only, that is, wihthout the freezer, it would operate at less power consumpton than a refrigerator/freezed combination because it would not have to cool to sub-freezing, but to only about 40 F.

Answer 2

In general a refrigerator is much more efficient than air conditioning. They work on the same principal, but an air conditioner is tasked with cooling a much larger, less airtight area than a refrigerator. Doors and windows also tend to open more often than the refrigerator door, further reducing the efficiency of air conditioning.

Answer 3

Higher ambient temperature, air infiltration, a load bigger than the design load,increase frequency of opening and closing doors, low level of coolant such as freon, thermostat malfunction, equipment failure and for the refrigerator the same as mentioned.
