In the operation of HVAC engineering, the application of heat exchangers is very extensive.
Although heat exchangers have different forms, in essence, the principle is to achieve heat transfer between cold and hot fluid bodies. Under the background of improving social and economic level, the proportion of heating and air conditioning energy consumption in the construction industry energy consumption is gradually increasing. How to make use of the energy of heating and air conditioning units more effectively is of great significance to energy saving and consumption reduction in the field of construction. Heat exchanger is a common equipment in HVAC engineering, which plays an important role in reducing energy consumption of equipment. In this paper, the change of heat exchange and resistance change of the heat exchanger in Linyi is carried out by experiment, and the operation and control of heat exchanger in the whole HVAC project is further analyzed.
First, the experiment and experimental data collection of the experimental data collection of three types of heat exchanger in HVAC project (plate type, casing type and tube type) to carry out the heat transfer performance test, and the system is fully simulated heating link.
Specifically, 3 heat exchangers in the Linyi heat exchanger factory operating system are parallel in the pipeline system, and they all adopt polystyrene stearic plastics with good thermal insulation performance with the related pipes. During the heat exchange process, the heat and cold water are used as the medium: (1) the hot water is pumped from the backwater device by the hot water pump and transported to the heater to make the temperature up to the predetermined value; (2) the hot water of the same temperature is transported to three different types of heat exchangers respectively; (3) in the heat exchanger, the hot water is hot with the low temperature water. Quantity exchange and then return to the backwater device. The cold water is pumped out of the cold water pump from the cold water pump, and the cold water is transported to the heat exchanger. After the heat exchange with hot water, it is also transported back to the cooling water tank.
