Heat power type ground source heat pump air conditioner

Abstract

The invention discloses a heat power type ground source heat pump air conditioner which is characterized by comprising a refrigerant circulation system and an expansion machine system. A power output shaft of the expansion machine system is in drive connection with a compressor of the refrigerant circulation system, and a condensation coil of the refrigerant circulation system is arranged in a generator of the expansion machine system. The refrigerant circulation system comprises an outdoor buried pipe system connected with a heat exchanger. The heat power type ground source heat pump air conditioner is reasonable in design, can effectively improve refrigeration energy efficiency ratio, can enable an electrically-driven refrigeration machine set to use low-grade heat energy to convert and combine mechanical energy, reduces electric consumption of the whole refrigeration air conditioning system, reduces the number of outdoor buried pipes, reduces construction cost, improves energy efficiency ratio of a ground source heat pump machine set and reduces power of a cooling water circulation pump.

Description

technical field [0001] The invention belongs to the technology of refrigeration and heating devices, and in particular relates to a thermodynamic ground source heat pump air conditioner which uses electric power as an energy source and improves the energy efficiency ratio of refrigeration and heating by utilizing waste heat. Background technique [0002] In the prior art, the refrigeration system mainly uses electric power as the energy source, which can be divided into centrifugal air-conditioning units, air-cooled air-conditioning units, piston-type air-conditioning units, screw-type air-conditioning units and other compression air-conditioning units; Energy, which can be divided into lithium bromide absorption air-conditioning units, ammonia-water absorption air-conditioning units, etc. according to different types of working medium. Compression refrigeration units using electricity as energy have a higher energy efficiency ratio than absorption air conditioning units, bu...

AI Technical Summary

Problems solved by technology

The use of the above-mentioned central air-conditioning in various buildings will have the following defects, such as the shortage of power supply in summer; the local air temperature in the city rises sharply, resulting in the heat island effect;

At the same time, the above-mentioned refrigeration and air-conditioning also consume a large amount of energy, which directly or indirectly increases the emission of CO2
