Ultralow-temperature heat source power generation and heat energy transfer system

Abstract

The invention discloses an ultralow-temperature heat source power generation and heat energy transfer system. The ultralow-temperature heat source power generation and heat energy transfer system comprises a positive cycle formed by connecting an evaporator, a compressor, an expansion machine, an engine, a condenser, a working medium pump and an expansion valve. According to the essence of the application of the ultralow-temperature heat source power generation and heat energy transfer system in the field of air conditioners, in summer, an indoor fan coil absorbs solar energy in air, part of heat energy is converted into electricity through the circulation of the system, and the other part of the heat energy is transferred and stored in the underground soil and underground water; in winter, the heat energy stored i the underground soil and the underground water is taken out, and heating is conducted. Namely, the solar energy is converted into electricity in summer and heat energy in winter, and accordingly a renewable environment-friendly energy utilization mode is achieved. The system is a revolutionary product of a central air conditioning system. The total manufacturing cost of the system is equal to that of a ground source heat pump central air conditioner, and the total power consumption of the system is 23% of that of a ground source heat pump heating-cooling central air conditioner and 14% of that of an ordinary heating-cooling central air conditioner. The system makes a great contribution for saving energy for public buildings.

Description

technical field [0001] The invention relates to an ultra-low temperature heat source power generation and heat energy transfer system. Background technique [0002] 1. China's per capita energy resource possession is at a relatively low level in the world. The per capita possession of coal and hydropower resources is equivalent to 50% of the world's average level, and the per capita amount of oil and natural gas resources is only about 1 / 15 of the world's average level. my country's annual primary energy consumption accounts for more than 90%, while the utilization rate of new energy such as wind energy, solar energy, and biomass energy is still very low. In order to ensure the sustainable development of Chinese society and create an environment in which our descendants can continue to survive and develop, China regards energy-saving technology and the development of renewable energy as the priority theme of scientific and technological development. [0003] Among the ener...
