General Application of Plate Heat Exchanger

Due to its compact structure, simple operation and maintenance, and high heat transfer efficiency, plate heat exchanger for central heating has become the preferred heat exchange product for heat exchange stations in urban central heating projects. It is suitable for water heat exchange system, steam-water heat exchange system and domestic hot water supply system, and plays an important role in the rational distribution of heat energy and improvement of heat management level.

The air conditioning system plate heat exchanger is widely used for the heat exchange of chilled water in the air conditioning system. The installation of plate heat exchanger near the condenser between the cooling tower and the condenser can play the role of condenser, prevent equipment corrosion or blockage, and save the operation time of the chiller unit in the transitional season.

In the high-rise building, the pressure blocker of the HVAC system with water, glycol and other heat-exchange medium often has very high static pressure. Using plate heat exchanger as the pressure blocker, the higher static pressure can be divided into several parts of smaller pressure, so as to reduce the pressure requirements of the system for pumps, valves, cold and hot water units and other equipment, and save the investment cost of equipment Use and operating costs.

Ice storage system adopts ice storage system of plate heat exchanger to adjust the peak load and valley load of the power grid. That is to use the chiller to cool at night and store ice in the ice storage tank to meet the cooling demand of the next day and reduce the peak load of air conditioning, so as to effectively save energy and operation cost.

Waste heat recovery in various fields, a large amount of heat is discharged into the surrounding atmospheric environment with the waste hot medium (such as the discharged domestic hot water, bath hot water, process cooling water, etc.) every day, resulting in a huge waste of energy. Due to the low investment cost, high thermal efficiency and extremely low-temperature difference requirements for the cold and hot medium, waste heat recovery can be converted into The secondary available heat energy is used in preheating condition. It has good social and economic benefits.
