Problems solved by technology

Due to the current use of electric drive, the power consumption is large, and some areas have a problem of power supply shortage in summer
At the same time, due to the lack of electric energy in my country's vast and remote areas, when using groundwater heat sources and underground soil heat sources, it will encounter great difficulties in using groundwater source heat pumps and soil source heat pumps.

Abstract

A compression-type geothermal heating-regrigerating system driven by fuel engine is composed of a compressor driven by fuel engine, an evaporator, a condenser, a throttle unit and underground water circulating pipeline. Two heat exchangers for cooling water and fume of engine and two energy-exchanging tubes for circulating water of air conditioner and hot water for daily life are equipped. Its advantages are full utilization of geothermal energy and the cooling water and fume heat of engine, and high heat efficiency.

Description

technical field [0001] The invention belongs to the category of thermal engineering, and in particular relates to a central air-conditioning thermal energy device. Background technique [0002] Groundwater heat source and underground soil heat source are inexhaustible and inexhaustible important energy sources with huge potential. Making full use of groundwater heat sources and underground soil heat sources is an important realistic and historical task at present and in the future. At present, ground water source heat pump and soil source heat pump are a new type of technology using underground heat source, which have been developed and applied rapidly in foreign countries and in some areas of our country. This kind of heat pump device has stable performance and high thermal energy coefficient, but it is currently driven by electricity. With the improvement of people's living standards, refrigeration and air-conditioning devices are rapidly po...
