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 thermal engineering category, and particularly relates to a central air-conditioning thermal energy device. Background technique [0002] Groundwater heat source and underground soil heat source is an inexhaustible and inexhaustible important energy source with huge potential. Making full use of groundwater heat source and underground soil heat source is an important realistic and historical task at present and in the future. At present, groundwater source heat pumps and ground source heat pumps are a new type of technology that utilizes underground heat sources, which have been rapidly developed and applied in foreign countries and parts 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 popularized in my c...
