Why install a heat wave plate heat exchanger
Autor:
1. The fluorine-water heat exchanger inside the main unit of the water system air conditioner plays the role of heat exchange with the secondary refrigerant. Generally, there are three types of heat exchangers, A. Casing type heat exchanger; B. Shell and tube type heat exchanger Heater; C. Plate heat exchangers, A and B are generally used in large units, the advantages are small pressure loss, low water quality requirements, not easy to block, C is generally used in small units, the advantages are small size and high efficiency. If it is the main engine of the water system, there must be a heat wave plate heat exchanger.
2. The household central air-conditioning water system uses a small heating boiler for auxiliary heating, and a plate heat exchanger, usually a heat wave plate heat exchanger, is connected in series before the main air conditioner behind the circulating water pump on the main pipeline. This is the water and boiler heating of the air-conditioning system. Water (the boiler has two loops of heating and domestic hot water) is used for heat exchange. When used in winter, set the boiler temperature, the furnace will boil water, reach the set temperature, the heating circulation pump will start to work, and the water will be 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 cancelled in order to save costs and reduce the cost, the heating furnace should be connected to the main pipe in parallel. When it is used in winter, the circulating pump of the main system will be connected to the boiler subsystem. The heating circulating pump grabs water, resulting in insufficient heating water flow in the boiler, and the boiler cannot play a heating role.
