Could a plate heat exchanger directly heat or cool water?
The plate heat exchanger is used for heat exchange, which can be heated or cooled. The heating time is called a plate heater, and the cooling time is called a plate condenser. The plate heat exchanger cannot directly heat the cold water. Because the plate heat exchanger is a direct heating device, it consists of a set of corrugated metal heat exchange plates. There are gaps between the heat exchange plates to facilitate the passage of the medium. It is specific The structure allows the cold and hot media on the left and right sides of the same heat exchange plate to pass through the heat exchange plate (usually made of metal). The heat is transferred from the lower end without the media being mixed. Here, the media on both sides of the cold and hot are independent Sealed system.
In the four aspects of heating, evaporation, cooling and condensation. It is a good heat exchange equipment to choose a plate heat exchanger in terms of domestic drainage and waste heat use. For example, if domestic drainage is water with heat, it can be used as a heat source to heat tap water and used as domestic hot water; the same can be said for waste hot water in bathing.
Plate heat exchanger is used in bath heating system
The hotel and bathing waste heat recovery is to concentrate the bathing wastewater in the waste water tank. The size of the waste water tank is determined according to the daily use flow of hot water or the maximum use flow rate or the hot water tank. Use pipes to let the waste hot water discharged from the bath pass through one side of the wide-channel plate heat exchanger, and the other side is connected to clean cold water.
Plate heat exchanger applied to domestic wastewater
The clean cold water and domestic waste hot water conduct cold and heat exchanges. The waste hot water changes from heat to cold. The clean cold water absorbs the heat of domestic wastewater and becomes hot. The hot water flows out from the other end and enters the thermal insulation water tank for domestic use. Waste heat recovery not only saves electricity bills but also confiscates the power for use.
