Carbon dioxide air conditioning system for building and building with air conditioning system

Abstract

The invention relates to a carbon dioxide air conditioning system for a building and the building with the air conditioning system. The carbon dioxide air conditioning system for the building comprises an indoor heat exchanger, carbon dioxide compressors, ground source heat exchangers and a reversing device. The indoor heat exchanger, the carbon dioxide compressors and the ground source heat exchangers are connected through a carbon dioxide circulation pipeline to form a circulation loop. The reversing device is arranged in the carbon dioxide circulation pipeline. The indoor heat exchanger is arranged in a building floor and/or a wall. The ground source heat exchangers are arranged underground. The carbon dioxide air conditioning system and the building have the beneficial effects that heat of geothermy or earth cooling is circulated to the building through carbon dioxide, and a heat source or a cold source is provided in a heat radiation exchange manner; cost is low, and energy consumption is low; and no pollution exists, and thermal homogeneity is good. The space of the building can be saved, indoor temperature is uniformly distributed, the indoor temperature fluctuation is small, and no blowing feeling or noise exists; and human body comfort and energy-saving benefits are better than those of a conventional air conditioner.

Description

technical field [0001] The invention relates to the field of building air-conditioning systems, in particular to a carbon dioxide air-conditioning system for buildings and buildings containing the air-conditioning system. Background technique [0002] At present, with the improvement of people's requirements for living quality and indoor comfort, as well as the development and further improvement of building energy conservation, the disadvantages of traditional building air-conditioning systems are becoming more and more obvious. In terms of refrigerants, the current air-conditioning systems at home and abroad use Freon as a refrigerant, but Freon will destroy the ozone layer of the atmosphere, resulting in a higher greenhouse effect. Due to the instability and high cost of ammonia (R717), it will cause unsafe factors in the refrigeration system, so ammonia (R717) is not suitable as an air-conditioning refrigerant. [0003] In terms of structural installation, conventional ...

Problems solved by technology

In terms of refrigerants, the current air-conditioning systems at home and abroad use Freon as a refrigerant, but Freon will destroy the atmospheric ozone layer, resulting in a higher greenhouse effect

Due to the instability and high cost of ammonia (R717), it will make the refrigeration system unsafe, so ammonia (R717) is not suitable as an air-conditioning refrigerant

[0003] In terms of structural installation, conventional air-conditioning systems are usually water-source heat pump units or air-source heat pump units, which use water as the refrigerant to be transported to the end fan coil to provide the required cooling or heat for the building. There are air conditioners on the floor. Pipelines and air outlets, in order to cover the air-conditioning water pipes and air pipes, usually need to design a hanging device, which takes up a lot of building space, which undoubtedly increases a certain amount of investment, and there are also large noise and high energy consumption per unit area. , low system efficiency, uneven temperature distribution, etc.
