XTL-V Heating Supply System of Wind-driven Enthalpy Increasing Heat Pump
Description
The system is mainly composed of four modules: wind drive, heat storage, jet enthalpy heating, and electronic control, in which the electronic control upper computer part combines stm32 microcontroller to realize the wind speed measurement and shaft control of the wind field. The internal working process of the integrated system can be summarized as follows: under wind conditions, the wind drives the lift type H-type Darrieus type wind wheel to rotate, converting the kinetic energy of the wind into the rotational energy of the vertical axis wind turbine; When the wind is strong, the kinetic energy is stored in the scroll spring through the input shaft, and when the wind is small, the energy in the scroll spring is output as power from the output shaft. A pair of sprockets drive the variable speed increasing gear mechanism to rotate. The gear mechanism connects the low-speed main shaft of the wind turbine and the high-speed rotating counter shaft of the compressor through the gear coupling sleeve. Through the internal gear transmission, the rotating speed of the rotating shaft is accelerated to realize the transformation of the shaft work of the jet increasing enthalpy compressor. The evaporator vaporizes the circulating working fluid R410A from low-temperature and low-pressure liquid to high-temperature and low-pressure gas, and absorbs heat. The compressor compresses the circulating refrigerant R410A through the external force, so that the R410A changes from high temperature and low pressure gas to high temperature and high pressure steam. After that, the heat is dissipated and condensed in the condensing heat exchanger, and the latent heat is released to the high-level heat source heat storage water tank to provide water heating for residents. The economizer is connected to the suction port of the compressor to improve the heat exchange efficiency of the condenser. At the same time, the circulating working fluid R410A is restored to a low-temperature and low-pressure liquid through the expansion valve throttling device to form a cycle. Under the condition of no wind, the good heat storage performance of the heat storage tank using PID parameter adjustment technology provides a continuous and stable heat source for the heat users, and realizes the purpose of continuous heating of the heating system under the condition of no wind and wind. In view of the climate and wind energy characteristics of the vast northern region of China, the system uses SolidWorks to establish a three-dimensional solid model of the heating system and assemble the solid model. According to the analysis of the system operation and heating efficiency, and the simulation experiment of the system heating finite element analysis, the feasibility, economic benefit and market value of the wind direct drive jet heating system are verified.
