A cooling tower is an installation that retreats heat from water by evaporation or conduction.
The industries use cooling water in various processes. As a result, there are also various types of cooling towers. There are cooling towers that create process water that can only be used once, before it is discharged. There are also cooling towers that create water that can be reintoduced in the production process.

Freshwater or central cooling system: Fresh water is used in a closed circuit to cool down the engine room machinery. The fresh water returning from the heat exchanger after cooling the machinery is further cooled by sea water in a sea-water cooler.
As discussed above, in the central cooling system, all the working machinery on ships are cooled down using circulating fresh water. This system comprises of three different circuits

The most common central cooling system is a split system, which includes an outdoor cabinet containing a condenser coil and compressor, and an indoor evaporator coil, usually installed in conjunction with your furnace or air handler. The compressor pumps a chemical called refrigerant through the system.
emperature control of the process can be affected using electric, pneumatic, electro-pneumatic and self-acting controls. This Module details some common applications including process vessels, heat exchangers and high temperature fail safe control.

The new digital thermostat does not use movable mechanical parts to measure temperature, but replaces it with a thermistor. Although some digital thermostats called "power stealing" (requiring an external power supply) generally use electronic circuits powered by 24 volt AC, basically, one or more standardized batteries must be installed in order to Operate a digital thermostat (but in some heating systems, electronic circuits based on the principle of thermopile will not be used, because these electronic circuits use "millivolt" as the basic voltage unit). Each digital thermostat has an LCD screen to display the current temperature value and the current setting value. Some temperature control models with more functions, in addition to the temperature setting function, also include time and date and time settings (there are also the date settings within a week today) to control the current and future daily temperature control. This is also for Comfortable and energy saving. Some of the more advanced digital thermostats have adopted touch screens, and even adopted X10, BACnet, LonWorks, and other related communication protocols for use in other home automation or smart building systems. Digital thermostats use relays or semiconductor components like triac as switches to control HVAC units. The unit with the relay can control the microvolt level system, but the sound of the switch will be heard when the switch is turned on or off. This is a PID temperature controller in operation (Delta DTK4848V01) with K-Type thermocouples and solid state relays. Some of the more expensive components will have a built-in PID controller. The PID controller controls the reaction of the thermostat. The PID controller The output of the HVAC unit is determined according to the current target temperature and the set temperature, not just turning it on or off. Such components may also cooperate with temperature sensors such as thermocouples and platinum resistance thermometers to receive signals. . Most household digital thermostats in North America or Europe are programmable thermostats, which can save about 30% of energy according to their default programs. Adjusting their settings may make them more energy-saving, but it is also possible It's getting worse.
