The Shell-and-condenser coil consists of one or more bare finned tubes or coils, of a prisoner in a welded steel shell. Condensation of water flows through the coil, while the refrigerant contained in the shell. Hot refrigerant vapor is to die in the upper body, condensation as it comes in contact with a cold surface water coils. The condensed liquid goes coil, collecting in the bottom of the hull, which also serves as a receiving tank. Careful not to overload this type of refrigerant system because the excess liquid stored in the lower part of the capacitor reduces the number of surfaces of pipes that remains exposed to refrigerant vapor. In these conditions, the saturation temperature of the refrigerant pressure and increase, decrease the capacity and efficiency of the system. As a rule, shell and coils, capacitors are used only to install and approximately 10 tons (by 35.2 kW) of power. Shell-and-capacitors, coils are cleared circulating approved chemical water heaters.
Increasing the temperature of the water passing through the die capacitor is a function of time diat remains in the coil.
The longer the water is hot refrigerant vapors, the higher the temperature of the leaving. Therefore, the majority of shell-and-coils, capacitors are manufactured with the use of split-water circuit, allowing the same capacitor is used in sewage treatment and water recycling applications. Split circuit condenser has a connection of the pipeline located in the center of the coil. Through the transfer of these three compounds in various configurations, the length of time that the water flows through the heat exchanger can be doubled or decreases twice. When the two halves die circuit coils connected in series, the capacitor is transmitted for wastewater treatment. Die when the coil circuits are transmitted parallel capacitor is transmitted to the water recirculation applications.
The colder the temperature of water used for wastewater treatment is the basis for these strategies. Municipal or well water used in the wastewater systems, as a rule, from 20 to 30 F (from 11 to 16C) cooler than the water recycling system. Therefore, pipelines voltage capacitor in series configuration doubles the time that the water remains in contact with the refrigerant, thereby increasing its temperature increases. As a result, out of the water almost the same temperature that is experiencing a water recycling system. This strategy allows saturated condensing temperature, the system will remain within its design parameters. For the same reasons, warm water recycling systems is transmitted in parallel, which allows only water to remain in contact with the refrigerant for one half of the time that it would if it were placed in series. Thus, with increasing temperatures do not increase beyond the design limits of the system..
