Components of the package

It controls all the tools and mechanical functions of the package. Package parts, including sensors, send messages to the control board, and the control board checks these messages to the rest of the parts. Sends orders. For example, if the flow switch works, the board orders the fan to work, and at this time the air compressor starts working, and at this time, the board commands the operation of the compressor. allows the gas valve to open or not; Does the pump work or not and... Programs are written in smart IC boards that give the package properties such as anti-freezing, anti-explosion or anti-jampage. Antifreeze is such that if the temperature of the package If it gets too low, the board instructs the pump to cycle the water intermittently to prevent freezing. To prevent the pump from jamming, turn the water every 21 hours for example.

Wall package: Residential heating and sanitary hot water have always been human needs. Considering the abundance of natural gas, technology aims to provide new ways of working for mankind. package Wall-mounted is a device that has replaced the gas heater and the central heating system and provides the hot water needed to provide heating of the environment by means of radiators and sanitary hot water for daily use.

It is one of the most important parts of the package and the factor of hot water flow to the radiators. The pump package is divided into two types: fixed speed and modular speed. We can mention the types of Willow, Granfus, and irj package pumps that are round left and right. How many revolutions does the package pump have? Fixed speed pumps have three types of speeds. When the package is used less or for example the area of ​​the house is small compared to the capacity of the package, the pump works at speed 1. when from If the package is used more or if the area of ​​the house is larger than the capacity of the package, the pump works at speed 3. In modular packages, if the required temperature of the package is high, the speed will automatically increase and when the desired temperature is reached, the pump speed will decrease.

What is the function of ntc sensor? It is also called sanitary thermal sensor and NTC. Its task is to measure the temperature of the outgoing water. This sensor measures the water temperature that enters the secondary converter He takes it and sends it to win. The board reduces or increases the heat of the flame relative to this temperature. For example, if the user sets the package to 50 degrees Celsius and the hot water temperature sensor to 20 degrees Celsius detects, the board orders to increase the degree of flame.

The system controls the pressure of the radiators with the package. If the pressure drops below 0.5 bar, the water pressure sensor sends a message to turn off the package. In fact, if the pressure drops, the pump will be pressurized and, most likely, there will be no water in the main exchanger.

The performance of Shir Sarah package and its failure The same valve is three-way and is placed in two-converter packages. When the water of the main exchanger is heated, as soon as the hot water is opened from the consumption valves, the three-way valve of the water path of the radiators closes and directs the water to the secondary exchanger to heat the water used. In the main board, such a program is written that when the hot water is opened, the pump to the valve or three-way valve Press to close the water path of the radiator and direct the water to the secondary exchanger.

The sensors confirm the consumption of water. A flowmeter is used in most of today's packages. The flowmeter contains a butterfly piece. When opening the water intake, the propeller starts working. At At this time, the magnet on the top of the propeller sends a signal to the circuit above it and finally reaches the main board with the message that the water supply has been opened. But inside the flow switch there is a magnet that goes up and down when the water flow is opened. When the magnet is down, it means the circuit is broken. When the water opens, the magnet rises. on top of There is an open circuit magnet that is connected when the magnet rises and the command is given to heat the water used.

Packaged gas tap and how to test if it is healthy This valve controls the gas entering the package and directs it to the burner as needed. This part is available in the market in two types: one with two bobbins and the other with three bobbins. The first coil is to open the gas to the burner. The second or perhaps the third bobbins are for gas pressure control.

Bhutan package fan and how the fan works It is an electric device and it is used to remove gases from combustion. The fan sucks the gas while working and confirms the opening of the chimney path. The fan has a propeller and a Electric motor, and a ventur to connect to the air compressor. The fan is connected to the combustion chamber on one side and to the exhaust pipe on the other side. Fan speed: Fans are generally divided into two types: fixed speed fans and modular fans. Most of the packages are fixed speed, but the more expensive packages, fan with modular speed have. These types of packages increase and decrease in speed compared to the height of the flame and gas produced. Fan voltage: The fan voltage is also different according to the size of the package. (Between 32 and 60 volts) If the combustion chamber of the package is small, the voltage will be between 30 and 35 volts. If the package compartment Types of Bhutan and Iran radiator fan packages: 28000 or 32000, the fan is used with a voltage of 45, 50 or even 60 volts. Location: The location of the fan is usually on the top of the package. Recently, some Korean packages came to the market, the fan was at the bottom of the package, and the fan speed increased and decreased compared to the flame performance, but According to the Iranian chimney system, these packages were not welcomed. Noteworthy: There are two types of packages in one category: with fan and without fan; In the fan package, we have a part called air pressure, which confirms whether the smoke path is open or not. In packages without sensor fan We have smoke so that if the smoke output is not working, the smoke sensor will send a message to the board to stop the package.

An exchanger is similar to radiators, where the incoming water enters from one side and exits from the other side. Its main task is to heat the water of the radiator system and also the water used from the taps. Its material is often made of copper. It has fins to keep the heat in. If the package has two converters, the main converter consists of spiral tubes that are placed on the flame and the water inside it is heated. If the package is a single converter (combined converter), a tube is placed on top of it to heat the water of the radiators, and at the same time, there is a thinner tube inside it, which is also It heats the water used from the taps. In this case, the programming of the board is such that when water is consumed from the taps, the pump stops moving and the consumed water is heated inside the thin tube. In the single-converter package, the converter is combined, and there is a pipe called the consumption water pipe in the path of the radiators, which heats the water. In packages with two converters, the converters are separate from each other and so on Packages with two converters are suitable for areas where the water is sedimented. In single converter packages, when the sedimented water is moved in the pipes, the said thin pipe will be perforated over time. And it will not be repairable.

Why does the expansion source get damaged and how do we know that it is damaged? It is in the form of a tank and is mounted on the back of the package, and its capacity is different from the capacity of the package. They often have a capacity of 6 liters in 24,000 W packages, 8 liters in 28,000 W packages, and 10 liters in 32,000 L packages. The function of this source is that there is a balloon-shaped material inside that is filled with air and its load pressure is between 0.7 and 1 atmosphere. Package maintenance training in Karaj Mahd Fan The task of this source is to control and keep the pressure inside the radiators system constant.

The package water pump and its task is to circulate water in the radiator system. The pump returns the water that is heated in the main exchanger in the return path and directs it to the radiators This process continues in the form of a cycle or a closed cycle between the radiators and the package. The hydraulic behind the pump is where the pump is stored and includes the automatic ventilation of the radiator system as well as the outputs of the secondary converter. This pump is placed on the return path for several reasons: First, because it guides the water more easily. Second, the water in the main exchanger is very hot, and if the pump is in the way, its life will be much shorter.
