The condensing unit is usually used for indoor and outdoor air conditioning systems. The condenser is only a heat exchanger, its use in the air conditioning system, and the existence of different types of condensers, found here.
The purpose of the condenser in the compressed refrigeration cycle is to convert the heat gas from the compressor to the liquid used in the evaporator. The condenser completes the action by removing enough heat from the hot gas to ensure that the pressure that is available in the condenser coagulates.
The type of water cooled condenser normally used is as follows:
Dual tube condenser: a condenser normally used for ammonia systems, including pipes in another pipe, or pipes inside. These tubes are placed horizontally to form a vertical bank. The whole device is fixed to the wall, and the water ammonia mixture enters the bottom part and flows through the inner tube. The vapor of the condensed refrigerant flows downward through the top because of the backflow.
Double tube condenser: it is a version of the double tube condenser, where water flows in the pipe and the refrigerant flows through the circular space between the two pipes. Condensing units are produced by placing compressors in the condenser.
Shell and coil condenser: it consists of a copper ring inside a steel shell. The water passes through the coil, the refrigerant vapor is discharged from the compressor, and condensation outside the cold tube. The condenser is economical, but its maintenance is difficult. If a leak occurs in the coil, the head of the shell must be removed and the coil is removed from the enclosure.
Shell and tube condenser: it consists of a number of tubes in a steel shell, with water flow in it and water vapor around the pipe. The steam condenses on the surface of the tube and then drops to the bottom of the condenser. In smaller places, there is a considerable amount of condensation surface available.
The capacity of the water cooled condenser depends on the temperature of the water, the amount of circulating water and the temperature of the refrigerant. With the temperature difference between refrigerant and water, the capacity will increase. By increasing condensation pressure, or lowering the temperature in the water, or by adding water to maintain a lower water temperature, the temperature difference can be extended.
