1. What are the three main parts of the heating system?
The heating system is to supply heat to the room by artificial methods, so as to maintain a certain temperature in the room to create a suitable life Conditions or working conditions of the device, mainly used for heating in winter. The three major components of the heating system are:
1. Heat source
It is a device that produces steam or hot water with parameters such as pressure and temperature , The heat source of the central heating system is generally the heating boiler, which is composed of the boiler body, the thermal system, the smoke and air system, and the coal transportation and ash removal system. The heat source of the personal heating system is a wall-hung furnace, etc.
2. Heat medium transmission pipelines
The piping system that transmits heat from heat sources to heat users, including outdoor heating pipe networks and indoor heating system pipes Among them, the laying methods of outdoor heating pipe network are mainly overhead laying and buried laying.
3. Heat-dissipating equipment
A device that transmits and dissipates the heat provided by the heat source and transmits it to the indoor air to achieve heating needs. The commonly used radiator is Radiators are also available in the form of floor heating.
Second, what is the working principle of the heating and heating system
The principle of the heating and heating system is:
Low temperature heat medium It is heated in the heat source, and after absorbing heat, it becomes a high-temperature heat medium (mainly in the form of high-temperature water or steam), which is sent to the residential room through the heat medium transportation pipeline, and the heat is released through the heat dissipation equipment to increase the indoor temperature; When the temperature is lowered, it becomes a low-temperature heat medium (low-temperature water), and then returns to the heat source through the recovery pipeline for recycling. In this way, the heat is continuously sent from the heat source to the room to supplement the heat loss in the room and keep the room at a certain temperature.
Three, what kinds of heating systems are there
There are many different classification methods for heating systems:
1 , According to the heat medium
It can be divided into three categories: hot water heating system, steam heating system and hot air heating system.
2. According to heat source
It can be divided into three categories: thermal power plant heating, district boiler room heating, and central heating.
3. According to the type of heating
It can be divided into three categories: central heating, low-temperature heating, and single-family heating.
