Abstract

The green energy-saving air-conditioning system is characterized by that the indoor air can be fed into phreatic water by means of refrigerating system of refrigerator, cooled and returned into the room to make circulation. In the course of circulation the air is passed through filter screen and active carbon layer and purified to eliminate "diseases" due to air-conditioning. If the room is big or it has need of accelerating refrigeration, the air can be passed through compressor, heat-insulated and compressed to rise its temperature, to raise its heat-exchange efficiency by enlarging temp. difference, and then the air is cooled, passed through the flow regulating valve and jetted, the expanded air can absorb lots of heat quantity implement refrigeration. It does not use freon, and fully utilizes underground water "cold source".

Description

A kind of power-saving green air conditioner

The present invention relates to utilize the air-conditioning method of underground water and room air heat exchange cooling.

All air-conditionings of domestic city cost an arm and a leg now, and power consumption is big, and the family that has is afforded, and with not rising, thereby popularize limitedly, and city suburbs and vast rural area are then because economic level is low basically without air-conditioning.On the other hand, air-conditioning uses freon (Freon) mostly both at home and abroad now, destroys atmospheric ozone layer, and room air can not purify appearance so-called " air conditioner disease " easily simultaneously.

About the destruction of ozone layer, become global environmental problem, caused the concern of countries in the world.UNEP (United Nations Environment Program) (UNOP) has held a series of international conferences, is intended to take measures to protect atmospheric ozone layer, in order to protect the global environment, should control until forbidding Chlorofluorocarbons (CFCs) (CFC _s) wait the production and the use of material, so in refrigerating and air conditioning industry, accelerate the application and the research of substitute technology, particularly vast outskirts of a town of China and rural area, require cost low, power-saving, gather materials on the spot, without the reduction room temperature method of freon, be one involve a wide range of knowledge, the problem significant to energy-saving and environmental protecting.

The warm summer in phreatic water winter forgives, water temperature winter summer substantially constant, and this is well-known common sense, and summer, ground water temperature was than also low 1～2 ℃ of winter in fact, and this is by the solar radiation cyclically-varying that is about half a year that the big thermal inertia of the earth's crust lags behind and form of heating.(whole nation has 20 provinces and cities approximately in the vast subterranean water level of China high area, except the plateau, the Northwest, southwest) its shallow top layer underground water, promptly the shallow superficial water (being different from the deep water in confined that underground bearing course is put aside) of being assembled by capillary is generally in underground 3～5 meters, water temperature has a small amount of variation 13 ℃～18 ℃ scopes with nearly rivers and lakes, southern and northern area and absolute elevation etc.

Underground water is national valuable source, arbitrarily groundwater abstraction is lowered the temperature, and to use be unallowed, but utilizing phreatic low temperature (relatively summer room temperature) to carry out room conditioning cooling (do not make water itself, air is direct contact water not) but is worth promotion and should makes full use of.This is energy-conservation, is again the useful project of heat energy storage from essence.

Purpose of the present invention is exactly for solving the above-mentioned drawback that existing air-conditioning exists, a kind of air-conditioning new method of lowering the temperature in the heat exchanger that places underground water that indoor hot-air is sent into being provided.

Realization of the present invention is other or indoor the phreatic well in the shallow top layer of certain depth (1) arranged by dwelling house, place the heat exchanger (2) of subterranean water level bottom in the well, suck room air and behind heat exchanger the reciprocal pipeline (3) in the return chamber, motor-driven air-introduced machine (4) and removable air filtration and purification apparatus (5) are finished.If require refrigerating capacity big (room big or effect of heat insulation difference etc.), can increase well depth, the lengthening heat exchanger improves air-introduced machine power, increases the cold air flow.As still not enough or require fast-refrigerating, then can with air-introduced machine (4) need not, when changing air inlet into air compressor (6) with little gas tank (7).During the air compression, gas temperature raises in the adiabatic compression process, thereby the exchange efficiency of heat exchanger is also high, because heat conducting speed is directly proportional with the temperature difference.Be compressed and heat up and through the cooled pressure-air of underground water, when indoor choke valve (8) decompression ejection, this gas will absorb heat in a large number and expand and fast-refrigerating.

The heat exchanging process of heat exchanger is reversible among the present invention, the gas higher than underground water temperature cools off after heat exchange, gas heating after heat exchange that phase inverse ratio ground water temperature degree is low, and underground water is cool in summer and warm in winter, northern China winter, air in the green house of vegetables can be down to zero following and generation frost when cold wave is attacked the time after midnight, thereby the raising temperature of shed of must heating.With summer the room temperature lowering process identical, air in the canopy can be sent the circulation of down-hole heat exchanger and improve temperature in order to save the energy, prevent frost, this is the another subbranch that the present invention uses.

Further specify structure of the present invention and preparation method below in conjunction with embodiment.

Embodiment 1:

At the indoor well of beating φ 110-φ 120mm, use mud off for aboveground, its inlet goes to the corner by pipeline, the degree of depth of well is decided according to local subterranean water level, requires shallow top layer underground water to have 1.5-2 rice dark, and general rainfall in summer is many, ground forms river rising in Ningxia and flowing into central Shaanxi stream and shallow top layer water level is improved, this is just helping the cooling in summer, and heat exchanger is about 2 meters 36-48 roots by the thin little aluminum pipe of (as 0.5mm) φ 4-5mm (or stainless steel tube) of tube wall and forms radiating tube, as shown in Figure 1.But weldering of ferrule aluminium or epoxy resin envelope, air intake duct is PVC plastic tube φ about 100, cover tubule in the bassoon, tubule φ about 60, being used to connect air-introduced machine gives vent to anger, hot-air advances the heat radiation tubule of heat exchanger through filter screen and activated carbon layer from bassoon, turns back after φ 60 tubules are finished the circulation of air cooling and purifying to air-introduced machine.

Embodiment 2:

For avoiding the air compressor machine noise, at the other φ 120-130mm well of beating of dwelling house, aboveground mud off, the degree of depth of well is that shallow top layer underground water 2-3m is dark, heat exchanger is formed as embodiment 1, this routine difference is to be added with power at 100W left and right sides air compressor (6), room air connects air compressor inlet through filter screen, compression back gas vent connects the outlet of little gas tank (7) gas tank and is switched to the big pipeline of heat exchanger under water, pipeline is galvanized iron conduit or the hard PVC plastic tube that certain mechanical strength is arranged, air pressure is at 1.3-1.5Mpa, if during compressor air suction inlet temperature 35 ℃ (room temperature in summer), (the compression exhaust outlet temperature is about 60 °～80 ℃ or higher) its scheme of installation such as Fig. 2, compressed air after cools down enters the chamber through tubule, by choke valve (8) decompression back ejection, air absorbs heat in a large number and expands and fast-refrigerating, to satisfy the requirement of large space fast cooling.

Good effect of the present invention is energy-conservation very remarkable, during the atural beat exchange, and the air-introduced machine merit Rate may diminish to below the 20W, and ozone layer is not had impact, and the continuous filtration, purification of air is lived the chamber Not only cold and hot suitable but also air cleaning is good for health, be worth vast outskirts of a town and rural area to be promoted, Replace existing use freon air-conditioner, the offspring benefits future generations.
