Central Air Conditioning Plate Heat Exchanger System

  Plate heat exchangers are ideal for heat exchange between liquid-liquid and liquid-vapor. The central air conditioning system may use heat exchangers Central air conditioning plate heat exchanger systemin two locations.

1. The fluorine-water heat exchanger inside the water system air-conditioning main unit plays a role in heat exchange with the secondary refrigerant. There are generally three types of heat exchangers: A-tube heat exchanger, B-shell heat exchanger and C-plate heat exchanger. A and B are generally used on large units, and have the advantages of low pressure loss, low water quality requirements, and low clogging. C generally uses small units, the advantage is small size, high efficiency, but also high water quality requirements. If it is a water system host, there must be a heat exchanger. If it is not a plate type, it must be one of other types heat exchangers.

2. The household central air-conditioning water system uses a small heating boiler to assist heating, and a plate heat exchanger is connected in series before the air-conditioning main unit behind the circulating water pump on the main pipeline.This is used for heat exchange between air conditioning system water and boiler heating water (both boiler heating and domestic hot water).When using in winter, the boiler temperature is set, the furnace is boiled, the set temperature is reached, the heating circulation pump starts to work, the water is output to the heat exchanger cycle, and the return water on the main pipe of the air conditioning system is heated.
