First step in refrigeration is evaporation. The next step is compression, which raises the pressure of the refrigerant vapor. Condensing is the third step and is where the heat transfer takes place. Expansion is the fourth step and is where the condenser cools the refrigerant even more, to a level below the condensing temperature.

In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.
As rule of the thumb, refrigerant condensing temperature should between 1-2 degreeC higher than the exiting water temperature, this temperature difference is technically called condensing temperature approach. I f the approach is below or above means, system is flooded with refrigerant or system got starve. Above method is also effective in determining if the condenser shell needs maintenance for sclale, sludge build up removal. I am refrigeration mechanic.
The condenser is a coil in a refrigeration system. It is on the low pressure side and is exposed to ambient air temp. The refrigerant goes through that and is cooled off and is then sent to the compressor.
Any refrigeration system (home air conditioner, refrigerator, automotive air conditioner...) uses the evaporation cycle of the refrigerant to remove heat from an object.The evaporation cycle of refrigeration systems is as follows:Refrigerant is compressed by the compressor. When the refrigerant is compressed the heat is forced into a smaller volume, raising the temperature of the refrigerant.The hotter refrigerant is then passed through a cooling coil, also called a condenser and air is passed across the hot coils, cooling the compressed refrigerant to room temperature, or close. The refrigerant, now under much higher pressure then changes state from a gas to a liquid.The refrigerant is then allowed to pass through an orifice, allowing the compressed refrigerant to expand. When the refrigerant expands it changes back to a gas, the temperature drops. The process is called "heat of vaporization".The chilled refrigerant is then passed through an expansion coil where something (air, water... whatever is being refrigerated) gets cooler.From there, the refrigerant is again compressed, starting the cycle over.As you can see, the condenser is essential to the refrigeration process. If the condenser develops a leak, the refrigerant is lost. If the condenser is kinked, refrigerant cannot get past. If air is blocked from passing over the condenser, the refrigerant cannot be cooled.

lose the heat from the refrigerant
Condensation on the outside of the condenser just makes the ice cube grow in size. Condensation on the inside of the condenser, assuming we are talking about a refrigerant type system, will limit the condensing temperature to somewhere below 32 deg.F lc
When the temperature of the air passing over the condenser is very low. Ex: Home A/c with out condenser, More heat can be removed if the out door ambient is 60f compared to 90f. Efficiency also increases with this.
