Underground three-dimensional parking garage using ground source energy

Abstract

An underground three-dimensional parking garage using ground source energy comprises an underground shaft with a parking device inside the underground shaft and is characterized by further comprising a plurality of cooling units and heating units, the cooling units and the heating units are buried underground from a lateral side and a bottom of the lower portion of the underground shaft. The cooling units and the heating units are composed of inner pipes and outer pipes nested with each other. The inner pipes are straight pipes with openings at two ends, the end faces of the outer pipes are closed, and liquid outlets are arranged at positions close to end faces in downward direction. Refrigerant water of an air conditioner enters from liquid inlet ends of the inner pipes to flow into the outer pipes through the inner pipes and flows out from the liquid outlets of the outer pipes. The underground three-dimensional parking garage overcomes defects of the existing garages, air conditioners and mechanical refrigeration devices and has the advantages of being convenient and reliable to use, low in cost required by refrigerating, free of environment pollution, simple in structure and the like.

Description

1. Technical field [0001] The invention relates to a three-dimensional parking garage, in particular to an underground three-dimensional parking garage which utilizes the ground to take cold and heat. 2. Background technology [0002] With the gradual warming of the global temperature and the continuous increase of various mechanical equipment, the demand for garages, air conditioners and mechanical refrigeration units is increasing. Most of the existing garages, air conditioners and mechanical refrigeration devices use refrigerating units to achieve cooling. Commonly used air conditioner refrigeration systems are mainly composed of compressors, condensers, filters, capillary tubes and evaporators. It has some disadvantages: the compressor is a mechanical structure, with short life and high noise; the refrigerant Freon seriously damages the ozone layer of the atmosphere, which is not conducive to environmental protection; it consumes a lot of energy and the cost of use is h...

AI Technical Summary

Problems solved by technology

It has some disadvantages: the compressor is a mechanical structure, with short life and high noise; the refrigerant Freon seriously damages the ozone layer of the atmosphere, which is not conducive to environmental protection; it consumes a lot of energy and the cost of use is high. Hundreds of electricity bills per month, which makes some families with poor economic conditions reluctant to use

[0003] Most of the existing central air conditioners in the garage are lithium bromide absorption type, using water as the refrigerant and lithium bromide as the absorbent absorption refrigeration technology to achieve heat exchange, mainly composed of generators, condensers, evaporators and absorbers, etc. It has some disadvantages: power saving but high energy consumption, heavy weight, complex structure and high cost; in the presence of air, lithium bromide solution is highly corrosive to ordinary carbon steel, which not only affects the life of the unit, but also affects Unit performance and normal operation
