供熱外管網(wǎng)與熱用戶的連接方式一般分為兩種：間接連接和直接連接。其中間接連接比較常見的是在換熱站或熱用戶入口處采用板式換熱器換熱機(jī)組進(jìn)行熱交換，這種方式需要建造專門的換熱站機(jī)房，設(shè)備和土建方面投資比較大。直接連接又分為三種：
   There are two ways to connect the external heating pipe network and the heat users: indirect connection and direct connection. Among them, indirect connection is more common in the heat exchange station or at the entrance of the heat user to use plate heat exchanger heat exchange unit for heat exchange. This way requires the construction of a special heat exchange station room, with large investment in equipment and civil engineering. There are three types of direct connections:
    1無混合裝置連接，即外網(wǎng)的熱水直接進(jìn)入到供熱系統(tǒng)再輸送到用戶家里，這種適用于小的供熱系統(tǒng)，應(yīng)用條件受限制；
    1. There is no mixing device connection, that is, the hot water from the external network directly enters the heating system and then is delivered to the user's home, which is suitable for small heating system, and the application conditions are limited;
    2裝水噴射器的直接連接，這種方式構(gòu)造簡單，但要求供回水之間有一定的壓差；
 Direct connection of water injector, which is simple in structure, but requires a certain pressure difference between water supply and return;
    3裝混合水泵的直接連接，這種形式需要增加混合水泵，會消耗一定的電能。隨著變頻水泵的普及應(yīng)用，這種方式的優(yōu)勢正在顯現(xiàn)，目前國內(nèi)已經(jīng)有很多供熱系統(tǒng)采用這種連接方式?；旌纤玫闹苯舆B接也叫做混水系統(tǒng)。
The direct connection of the mixing water pump needs to increase the mixing water pump, which will consume a certain amount of electric energy. With the popularization and application of variable frequency water pump, the advantages of this method are emerging. At present, there are many heating systems in China that adopt this connection method. The direct connection of the mixing pump is also called the mixing system.
    混水系統(tǒng)的原理：混水系統(tǒng)一般設(shè)置在各建筑單元熱力入口的地下室里，其原理是把從用戶端出來的回水通過混水旁通管與從供熱外網(wǎng)來的二次供水進(jìn)行混合。液位變送器應(yīng)用：分布式混水機(jī)組供熱方式和傳統(tǒng)供熱系統(tǒng)
Principle of the mixed water system: the mixed water system is generally set in the basement of the thermal entrance of each building unit. Its principle is to mix the return water from the user end with the secondary water supply from the external heating network through the mixed water bypass pipe. Application of liquid level transmitter: heating mode of distributed mixed water unit and traditional heating system
