Abstract

A kind of energy-saving ground temperature air-conditioning system, be to utilize abundant underground water or earth sand bed to constitute about one 22 ℃ big volume isothermal body, carry out heat exchange with the ground environment air, then with behind the exchange equilibrium near the air suction of ground temperature or be pressed into indoor purpose to realize regulating the room temperature.The long-time running continuously of this system has the advantage of small investment, power consumptive province, economizes on electricity more than 80% than common refrigerating and air-conditioning, than tens times of cooling/heating air conditioner power savings, high temperature season can be turned down more than room temperature 10C °, can keep winter room temperature more than 18 ℃, is suitable for vast family and office and uses.

Description

Energy-saving ground temperature air-conditioning system

The present invention is that a kind of underground water or earth sand bed of utilizing is as the heat exchange medium of air and the air-conditioning system that regulates the room temperature.

In the epoch of World Economics high development at present, the energy is very in short supply, especially the imbalance between power supply and demand of China is very outstanding, therefore electricity consumption in life is all controlled, therefore, existing various air-conditioning systems are excessive because of its power consumption, operating cost is high hangs back general family or office, and people press for and a kind ofly invest little, power consumptive province, operating cost is low and can be by the air-conditioning system that numerous family or office accepted.

The air-conditioning system that purpose of the present invention is intended to provide a kind of reduced investment at the deficiencies in the prior art, power consumption is little, operating cost is low, summer or winter can both be moved for a long time continuously, underground water that this system's utilization is abundant or earth sand bed are as the air heat exchange medium.

Main points of the present invention are: according to the most of area of earth's crust skin temperature all is 22 ℃ of these rules of the left and right sides usually, and the water, earth sandstone etc. that utilize the stratum constitute one the 22 ℃ jumbo isothermal body in the left and right sides, carry out heat exchange by local air on these jumbo isothermal materials and the ground, the temperature behind its exchange equilibrium still near or equal ground temperature.This big volume isothermal body becomes the source of this air-conditioning system heat absorption or heat supply, so just can save now that air-conditioning system is warming up to 22 ℃ (winters) or reduces to 22 ℃ of big energies that consumed environmental gas, and only use the extremely low electric energy will be near indoor the getting final product of air suction (or being pressed into) of ground temperature.The present invention adopts a low power consumption air exhauster or pressure fan that heat exchanger and underground water or the silt of ground surrounding air in missile silo is carried out after the heat exchange, become the air approaching, again by the pipeline suction or be pressed into the indoor adjusting that realizes room temperature with ground temperature.Heat exchanger in the missile silo is selected for use dissimilar and different modes by size and user's actual conditions of air-conditioning area, its heat exchange medium can adopt water or earth sand bed respectively, heat exchange method can adopt four kinds of modes such as direct or indirect heat exchange of earth sand bed in the direct or indirect heat exchange of air and well water, air and the well again, adopt wherein any all can, but the best results of carrying out heat exchange in first kind of mode.

Below in conjunction with accompanying drawing invention is elaborated.

Fig. 1 is a system schematic of the present invention;

Fig. 2 is air and well water direct heat switch schematic diagram;

Fig. 3 is air and well water indirect heat exchange means schematic diagram;

Fig. 4 is a silt direct heat switch schematic diagram in air and the well;

Fig. 5 is a silt indirect heat exchange means schematic diagram in air and the well.

Among the figure, 1-ground, 2-inlet duct, 3-air inlet pipe, 4-well, the 5-heat exchanger, 6-well lid, 7-ground temperature letter shoot, 8-pipe clip, 9-air exhauster, 10-ground warm air, the outdoor body of wall of 11-, the 12-room, the 13-pressure fan, the arrow indication is an air-flow direction among the figure.

With reference to accompanying drawing, the present invention includes well (4), air inlet pipe (3), ground temperature letter shoot (7), heat exchanger (5) and air exhauster (9) or pressure fan devices such as (13), as adopt air and water or sand bed direct heat exchanged form (as Fig. 2, Fig. 4), then pressure fan (13) is set in air inlet pipe (3) porch, ground air is pressed into well (4) bottom by air inlet pipe (3), after directly carrying out heat exchange with WIH (Fig. 2) or silt (Fig. 4), air (10) near ground temperature (22 ℃) is sent in the room along carrier pipe (7), and this moment, well water or silt just were equivalent to heat exchanger (5); If adopt air and water or silt indirect heat exchange form (Fig. 3, Fig. 5), then carrier pipe (7) exit be provided with air exhauster (9) will be with well water or silt heat exchange after ground warm air (10) be evacuated to indoor continually, air inlet pipe this moment (3) links to each other with carrier pipe (7), air is well water or silt indirect heat exchange in pipe and outside the pipe, and the connecting pipe between air inlet pipe (3) and the carrier pipe (7) is equivalent to heat exchanger (5) at this moment.Simultaneously, also can establish a simple inlet duct (2) in air inlet pipe (3) porch,, filtered air effect dustproof to play, and well lid (1) is set at well head, in ground temperature letter shoot (7) outside the insulation anti-condensation material is set.Can adopt single group or organize heat exchanger more and carry out combining forms such as serial or parallel connection according to actual conditions, corresponding connecting pipe also can adopt size, serial or parallel connection method that material is different.Air exhauster or pressure fan are selected different capacity for use according to actual conditions.

Air-conditioning system of the present invention can reduce room temperature more than 10 ℃ at high temperature season, can keep winter room temperature more than 18 ℃, owing to adopt underground water or earth sand bed to constitute one the 22 ℃ jumbo isothermal body in the left and right sides, thereby for air-conditioning system provides endlessly ground warm air near 22 ℃, system's continuously-running, and it is low in energy consumption, economize on electricity more than 80% than common refrigerating and air-conditioning, than tens times of heating air conditioner power savings, its cost is also lower than a small-sized wall-through type air conditioner, and the air-conditioning area can enlarge tens times, and this air-conditioning system is widely used in general family and office uses.
