Heat-exchanging air-conditioner for indoor air and underground thermostatic layers

Abstract

An air conditioner which uses earth energy to heat exchange room air with underground layer of constant temperature includes mainly underground water pool, U heat exchanger, fan, air pipe, modulator and relevant control circuits. It is normally used to regulate the temperature for flat house or villa and it is an ideal green air conditioner which sets the underground water pool in between 7-10 meters of constant temperature layer having average temperature of the year at local area as the stored water carrys on heat exchanging with adjacent underground layer for heat balancing. It absorbs theroom air into U heat exchanger dived in the strored water to raise exchanging result and to send it back room for regulating the room temperature with not extracting any water and the energy comsuption only as 40% or below of the existing air conditioner.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioner system for heat exchange between indoor air and an underground constant temperature layer. Background technique [0002] At present, room air conditioners generally use air conditioners with compressors or central air conditioners. Because these air-conditioning equipments are expensive and consume a lot of power, they are difficult to popularize for units and individuals with poor economic conditions. [0003] It is well known that groundwater whose water temperature is stable at 12-24°C all the year round is used for heat exchange in a relatively shallow aquifer under the ground. For example, Chinese Patent Application No. 97105385.5 discloses "an air-conditioning system using groundwater refrigeration". The two ends of the heat exchanger are respectively connected, and the ground water is pumped out through the pumping well to exchange heat with the heat ex...

AI Technical Summary

Problems solved by technology

This kind of air-conditioning system that uses groundwater as a cold source or heat source may encounter a problem in specific applications: there must be a large distance between the backwater well and the pumping well, otherwise, the heat discharged from the backwater well will not be released underground in time. It will mix with the water in the pumping well, and eventually the system will lose or weaken the heat transfer efficiency

In this way, two new problems have arisen: 1. The cost of digging wells for newly opened wells, pipeline growth costs, construction costs and other costs have been increased.

2. To occupy a larger site, it is difficult for some units with small sites (such as urban residents)

3. Continuous extraction and exploitation of groundwater sources, resulting in waste of water resources and seriously affecting the ecological environment

It is obvious that the invention must have groundwater to work, and it cannot work in the dry season

There is still the problem of mining groundwater sources to pollute the ecological environment
