For those who don't know about plate heat exchanger, they may ask such a question: can plate heat exchanger be directly used to heat or cool water separately? What principle does it use to heat or cool? Let me introduce you today.

The original plate heat exchanger can not directly supply water to heat or cool alone, it needs two or more kinds of cold and hot media to transfer heat. First of all, it is necessary to understand the composition of the equipment. The heat exchange part of the equipment is assembled by a series of corrugated plate groups. The cold and hot media have their own channels in these plate groups. The heat is transferred from the hot side to the cold side, and the heat loss in the transfer process is almost negligible. For example, in the heat recovery and utilization system of industrial waste water, the high heat loss is almost negligible A large amount of industrial waste water is transferred to the low temperature side through the plate heat exchanger, and the medium temperature of the low temperature side needs to be heated is increased, so the heat can be recycled.

After introduction, do you also understand this problem? Plate heat exchanger can not directly heat a certain medium alone. It is an equipment for efficient heat exchange between two or more kinds of cold and hot media.
