As for plate heat exchanger, many people may know it well. For example, the central air conditioning system uses plate heat exchanger. Then, let's briefly introduce it to you.
1、 The fluorine-water heat exchanger inside the air conditioning host of the water system plays the role of heat exchange with secondary use of refrigerant. Generally, there are three different forms of heat exchange through the heat exchanger, A. casing heat exchanger; B. Shell and tube heat exchanger; C. Plate heat exchangers, A and B can generally be used on some large units, with the advantages of low pressure and loss, low water quality standard requirements, and not easy to block. C is generally used on small units, with the advantages of small size and high efficiency. If it is the water system management host, there must be a heat exchanger. If it is not the plate type, it is also due to one of the other organizational forms.
2、 The household central air conditioning water system can use the heating boiler technology of small enterprises to assist heating, and will also develop a plate heat exchanger in series behind the circulating water pump and before the air conditioning host on the main pipe. This is used for the heat exchange between the water of the air conditioning management system and the boiler heating water. When the main water is used in winter, set the boiler temperature, boil water in the furnace, reach the target set temperature, and the heating circulating pump starts to work, The water is output to the heat exchanger for circulation to heat the return water on the main pipe of the air conditioning system. If the heat exchanger is canceled in order to save the resource cost and reduce the project cost continuously, the heating furnace should be connected in parallel with the main pipe. When used in winter, the circulating pump of the main system will compete with the heating circulating pump of the boiler subsystem, resulting in insufficient heating water flow of the boiler, and the boiler can not play a heating role; Another way to cancel the heat exchanger is to add a gate valve or stop valve to the main pipe of the boiler in parallel, turn off the valve when heating, and then cancel the boiler's circulating water pump, because their problem is equivalent to connecting the boiler in series with the air conditioning pipe system, and the small circulating pump of the boiler will suppress the flow of the circulating pump of the main system, so we can only cancel it, This kind of situation can only be used for boiler heating assistance without providing domestic hot water. Otherwise, because of the principle of boiler industrial structure, as long as the air conditioner is turned on, the domestic hot water will not burn.
The above is all about why the plate heat exchanger is used. I hope it can help you.
