Natural air conditioning system

Abstract

The invention relates to a natural air-conditioning system which comprises a basement (2), a superstructure (1) which is positioned above the basement (2) and a ventilation structure which is used for communicating the basement (2) and the superstructure (1), wherein, the basement (2) is provided with an air inlet (33) which is communicated with the ground; the natural air-conditioning system is characterized in that the superstructure (1) is provided with a ventilation well (5) which is communicated with the basement (2), the top end of the ventilation well (5) is extended to the top part of the superstructure (1) and is communicated with the outside atmosphere; furthermore, an exhaust port (51) which is communicated with the ventilation well (5) is arranged in the internal space of the superstructure (1); and the ventilation structure comprises an air inlet mechanism (3) and an air supply mechanism. Compared with the prior art, the natural air-conditioning system of the invention has the advantages of achieving the purpose of mutual supplement between the indoor temperature and the underground temperature by the air by slightly improving the prior ventilation system, allowing the indoor temperature to be warm in winter and cool in summer, realizing the reuse all year around, greatly saving the power, having lower improvement cost and being applicable to popularization and application.

Description

technical field [0001] The invention relates to an air-conditioning system using natural temperature difference, in particular to a natural air-conditioning system which utilizes the temperature difference between the ground and underground to integrate the existing building basement ventilation system. Background technique [0002] Existing household air conditioners are mainly assembled from compressors, condensers, evaporators, and fans, and usually require the refrigerant Freon. It is still difficult for urban residents with low income and rural areas in underdeveloped areas to popularize, and Freon is easy to pollute the environment. [0003] For this reason, many people use natural conditions to build air-conditioning systems, such as the Chinese utility model patent "Energy-saving Air Conditioner" (authorized announcement number: CN2450578Y) whose patent number is ZL00257563.9. device, air pump and underground pipe, the air pipe is the air pipe and the suction pipe r...

AI Technical Summary

Problems solved by technology

Although great improvements have been made, there are still the following deficiencies: first, the design of the exhaust system of the house is not good, and the natural air-conditioning system is not well integrated with the original HVAC system, which affects the circulation of air flow; secondly, the house The air intake system inside cannot adjust the air volume at will according to the actual climate and occasion; thirdly, the existing air intake system is noisy, which affects people's normal work and rest; finally, the practicability is not good, and it does not have the conditions for large-scale promotion and application, and The ratio of construction investment to profit is not high, and it is inconvenient to use
