The package can be considered one of the most popular heating systems of buildings in recent years, which is used to heat the interior of the building and also supply water. The package is one of the great alternatives for motor homes, which has been highly welcomed for purchase and installation in the building due to its numerous advantages.
Wall packages that have a small size in the building. residential, office and commercial are used. The independence of the package is one of the advantages that exist for them, and in addition, low energy consumption as well as high quality and beautiful appearance encourage people to buy this device. But sometimes, there may be problems and There will be various damage to the package that needs to be repaired by the package repairer. Among these problems, we can mention the boiling of the package, which has caused problems for people and should be solved as soon as possible.
Anatomical Package Parts
Electronic board: This part can be considered as one of the most important parts in the wall package, which by receiving information from sensors and user commands, gives various commands to other parts. In packages that are digital, the electronic board has two pieces, and one is used as a control board and the other is used for the display.
Sensors of the wall package: Various sensors in the wall package are They are used to report the status of the device to the package board. Among the sensors used in the package, we can mention NTC sensor, air and water pressure switch, flow switch, flow regulator and flow meter, limit thermostat, smoke thermostat and room thermostat.
Heat exchanger Package: It is one of the parts that consists of a number of reciprocating pipes and causes the heat produced by the burner to be transferred to the water used.
Circulator pump Wall package: It is one of the important parts of the device that causes the water to start moving in the heating circuit of the package and its place is in the heating return path. /b> is a system in wall packages that deals with the air evacuation of the package. If this part is damaged, the presence of air around the pump blades will cause serious damage to the pump.
Wall package safety valve: In order to prevent the pressure in the heating circuit from increasing too much and not damaging the various parts of the package, a part called the safety valve is used. This valve has a pressure of 3 bar and drains the excess amount of water in the heating circuit. The water is reported to the device board and the flowmeter does the same thing and in some package models it is used instead of the flow switch.
Thermistor wall package: Thermistor is actually called a resistance whose value changes with the function of temperature and includes NTC and PTC. Minimum water pressure safety is also said to work when the water pressure is less than 5 bar and does not allow the package to be started. If this part is damaged, there will be a possibility of serious damage to other parts of the package.
Source of package expansion: The extra pressure applied to the heating circuit causes leakage and The pressure increases in the heating circuit, which neutralizes the source of the expansion of this pressure and prevents damage to the package.
Types of packages based on the number of converters
According to the number of converters, the packages are divided into two categories: single-converter package and double-converter package. In single converter packages, heating as well as hot water supply is provided through the flame directly. The water can be heated by the flame. In this type of packages, there is a possibility of sediment clogging in the package parts and the water temperature fluctuates more. But this type of package is not active in summer and hot water is provided faster. In addition, the possibility of failure in this type of package is less than in two-converter packages.
In double-converter packages, the pump is active in winter to provide heating, and when the water circulates in the main converter. The radiators are heated and the water used is also heated. These types of packages have less temperature fluctuations in the water consumed and due to the use of two converters for heating and supplying hot water, they also produce less sediment.
