1、 Working principle of plate heat exchange unit.
1. Control principle
The plate heat exchange unit adopts an automatic control system, which is mainly composed of sensors, controllers (measurement and control functions), communication systems, electrical control cabinets, etc.
The sensing elements include outdoor temperature sensor, flowmeter, pressure transmitter, temperature transmitter, heat meter, electric control valve, liquid level gauge, frequency converter, solenoid valve, etc.
Through sensors and actuators, the controller can collect and control the data of the equipment.
2. Working principle
The plate heat exchange unit continuously converts the heat of the main network into the required heating water. The steam is controlled by the temperature control valve and enters the plate heat exchanger from the inlet of the unit side according to the flow required by the heating system. The heat exchanger heats the water by indirect heating and flows out from the main side outlet.
The secondary water is filtered and discharged, and then enters the heat exchanger through the secondary circulating pump, or is heated by steam (hot water) before being used by users, providing hot water supply of various temperatures such as air conditioning, heating, domestic water, etc.
2、 Characteristics of plate heat exchange unit.
1. The water temperature is controlled by an intelligent thermostat or computer. The water temperature can be set according to the program, and can change with temperature and time. It has the advantage of high temperature regulation accuracy.
2. The industrial control computer can store various parameters, such as standard part temperature, heat medium quantity, heat medium pressure, outdoor temperature, condensate temperature, water supply pressure, etc.
3. Stainless steel heat exchanger is adopted, with small floor area and small equipment volume.
4. The water supply of the system is controlled by frequency converter, with automatic voltage stabilization and automatic water supply.
5. The circulating pump is variable in quantity and frequency.
6. Standard module design, control content through user selection, and reduce cost investment.
The above is the composition characteristics and working principle of the heating plate heat exchange unit introduced to you. I hope it can help you!
