The heat exchange unit can play an important role in many places. It can be widely used in hotels, restaurants and commercial buildings. Of course, it can also be widely used in the heating of office buildings, residential areas and enterprises and institutions.
Analysis on the difference between water-water heat exchange unit and steam-water heat exchange unit
There is no difference between heating heat exchange unit and steam-water heat exchange unit in essence, because they belong to heat exchange equipment, but their overview, structure, characteristics and application are different and different!
1、 From their overview:
The heating and heat exchange unit is mainly composed of heat exchanger, pressure stabilizer, circulating pump, make-up water pump, dirt remover, control cabinet, etc. Some customers can add condensate water tank or make-up water tank and soft water device according to their own needs, and the main purpose is to achieve the effect of the heat exchange station. So it is generally applied to the heating of high-grade hotels, restaurants, offices, schools, working conditions, army heating, air conditioning, bathing water, domestic hot water, swimming pool water, etc.
Steam-water heat exchange unit The integral heat exchange unit can be used for both water-water exchange and steam-water exchange, and can be equipped with automatic constant pressure water make-up device, water treatment equipment, water tank, water pump frequency conversion control, temperature control valve, remote communication control, etc., thus forming a complete heat exchange station. With standardized and modular design, complete configuration, convenient installation, high efficiency and energy saving, the unit has been widely used in residential district centralized heating, central air conditioning, domestic water, enterprise production process water and other systems.
2、 From their structure:
Heating and heat exchange unit:
1. Heat exchanger, circulating pump and make-up water pump
2. Valves, instruments, software heads and connecting pipes in the unit
3. Intelligent control system can realize automatic operation and unattended
4. The manufacturer is responsible for the assembly of the unit and has damping device
5. The unit bottom frame channel steel shall not be less than 8-10cm to prevent the machine from being flooded.
Steam-water heat exchange unit:
Heat exchanger;
Circulating pump;
Electric control cabinet;
Water make-up and constant pressure device;
Valves, pipelines and accessories necessary for temperature control, unit base and unit pipeline connection.
3、 From their characteristics:
Features of heating and heat exchange unit:
1. It can be adjusted automatically according to user needs, which is more humanized;
2. Optimized design, reasonable layout, small head loss, compact structure and small floor area of the whole unit;
3. The water supply of the system adopts frequency conversion control, automatic water supply and voltage stabilization.
4. The standard modular design can flexibly select the control content according to the user's situation and reduce the investment.
5. Centralized digital display of operation parameters is convenient and reliable.
6. It makes the operation simple, installation and maintenance convenient. The control heat exchange regulation of the heat exchange unit adopts the control elements and systems of imported or domestic famous brands, which are reliable in operation, excellent in performance and high in automation. You can master the operation of the heat exchange unit with simple training.
Features of steam-water heat exchange unit:
1. The industrial computer or intelligent regulator is used to make the water supply temperature intelligent control, that is, the water supply temperature can change with the outdoor ambient temperature, standard room temperature and time according to the program setting, with high heating quality and energy saving.
2. The industrial control computer displays, stores and prints various operating parameters, including: heat medium flow, heat medium temperature, heat medium pressure, power supply
Heat, outdoor temperature, standard room temperature, water supply temperature, condensate temperature, water supply pressure, etc.
3. During steam-water heat exchange, condensate heat exchange section and condensate temperature control shall be set to make full use of condensate heat.
4. The circulating water pump can operate with variable frequency.
5. The system adopts frequency conversion control, automatic water supply and voltage stabilization.
6. The standard modular design can customize the adjustment control system according to the user's situation, reducing certain investment.
7. Simple operation, reliable operation and convenient maintenance.
4、 From their application: (This is their similarities)
Both the heating heat exchange unit and the steam-water heat exchange unit play a great role, because the heat exchange unit is the guarantee of our warm and comfortable life. With the heat exchange unit, we can provide a good environment that meets the requirements of the production process. All these are given to us by the heat exchange unit. In fact, the heat exchange unit is an ideal heat exchange equipment that uses industrial waste heat heating system. It can provide heat and electricity in a centralized way, and can also provide heat in a boiler area.
The heat exchange unit can play an important role in many places. It can be widely used in hotels, restaurants and commercial buildings. Of course, it can also be widely used in the heating of office buildings, residential areas and enterprises and institutions.
