Description

Small-sized fire coal, oil, gas central authorities air conditioner

The utility model is a kind of small-sized changes in temperature heat power equipment, belongs to the air-conditioning field of heating, and is relevant with heat transfer technology, combustion technology, automatic control technology again.

At present, small-sized household heating air conditioning equipment mainly contains three major types.One class is conventional heating hot water stove, and other powers up the air conditioner composition, and this equipment is actually heating and two separate cover systems of air-conditioning.Two cover autonomous system independent operating and uses, irrelevant mutually.Shortcoming is that complexity is installed by system, and it is attractive in appearance to destroy the room, and two complete equipment above times of half a year are idle, and utilization rate of equipment and installations is low.Another kind of is the heat-pump-type cooling and heating air conditioner.This kind air conditioner is at northern China cold district in winter, and heating effect is not only poor, and power consumption is big, only can be as the short-term operation of heating transition season.Last class is external small-sized central air conditioner.This kind air conditioner and preceding two classes have relatively had substantial technological improvement, and it unites two into one heating air conditioning.Shortcoming is only to use combustion gas to be the energy, and the air-conditioning temperature-reducing device places the body top, causes equipment size too high, be difficult for installing, and this kind air conditioner does not have hot water function.

The utility model purpose is the deficiency at above-mentioned three types of products, a kind of various energy resources of using in conjunction with China's fuel characteristic design, multi-functional small-sized central air conditioner, it not only uses fire coal, fuel oil, combustion gas to do the energy, but also has heating, hot water, multiple function, compact conformation, thermal efficiency height such as cooling, energy-saving effect is remarkable.

Essence of the present utility model is that this small-sized central air conditioner is combined into one the generation of hot blast and cold wind, adopts the augmentation of heat transfer technology to realize highly effective air heating or cooling, reaches compact conformation, multipurpose, energy-efficient, purpose of safe operation.

Describe in detail below in conjunction with accompanying drawing.

This air conditioner is mainly by forming with lower member: 1. heating tube, 2. burner hearth, 3. hot water generation chamber, 4. air inlet duct, 5. insulation Backboard, 6. cooler, 7. blower fan, 8. dividing plate, 9. flue, 10. casing, 11. passive controlling valves; 12. fire door, 13. distributions every Plate, 14. side pneumatic panels, 15. fire sealing covers, 16. compositions such as seat, 17. fire grates, 18. furnace linings, 19. fins of banking up a fire. Air conditioner is main Be divided into the generation hot blast, cold wind, hot water three part-structures. Hot blast takes place main by the seamless flue gas with the internal disturbance sheet The outer wall of pipe 1, burner hearth 2 and fin 19 reinforcements thereof add hot-air and realize. Hot water is heated by the hot water generation water jacket of burner hearth one side Realize. Cold wind then relies on the air-conditioning temperature-reducing evaporation coil cooling-air that is driven by outdoor air-conditioner to finish. Air circulation then relies on Blower fan 7 is realized. Fire sealing cover 15 and the seat 16 of banking up a fire are cast-iron structure, and the fire sealing cover parallel is realized banking up a fire and temperature adjustment merit on fire Can, to guarantee coal cold-warm machine safe combustion. Passive temperature-sensing valve 11 adopts the paraffin wax expansion principle to make. Work as air themperature When surpassing 45 ℃, the passive valve unlatching of being heated, cold air is inhaled into and reaches further thermoregulatory effect in the air conditioner. Furnace lining 18 is Shaping refractory has better heat-resisting heat-proof quality, prevents that the metal firebox wall from burning out. Postnotum 5 and cooler 6 left sides thereof Casing inner wall is all used 8 millimeters thick foam thermal insulations, in case cold scattering and dewfall.

The utility model course of work is as follows: light burner hearth 2 winter, start blower fan 7, then indoor return air is by air inlet duct 4 warps Enter air channel, air conditioner bottom after the filtration, cold wind is at first heated by the hearth outer wall with fin, and then rises to machine through the crosswind road Turn back downwards through pneumatic panel 14 in the body top, further be heated pipe 1 heat temperature raising after, again through dividing plate 8 bottoms, do not pass fortune The cooler 6 of row is squeezed into the warm keeping air channel through blower fan 7, enters in the room. Then the gas after the cooling further repeats to follow Ring. When heating temperature need be reduced in the room, moved by hand fire sealing cover 15 was adjusted burning and is realized. When the burner hearth fired coal combustion, stove Water in the hot water generation chamber 3 of thorax one side is heated by burner hearth, and the hot water after being heated rises in the water storage tank by circulation line and stores Hide stand-by, (not shown). Summer, burn-out, priming chamber dispatch from foreign news agency air conditioner (not shown) produces refrigerant and passes through 6 evaporations of air-conditioning temperature-reducing device siphon away airborne heat, reach air cooling-down dehumidifying purpose. The cold air of being lowered the temperature is through blower fan 7 Squeeze in the air channel, room. Air after the intensification then enters the air conditioner repetitive cycling by air inlet duct 4.

When adopting fuel oil or combustion gas to make the energy because be difficult for producing problems of excessive heat, so remove in the air conditioner temperature-sensing valve 11, The structure of banking up a fire 15,16 and the parts such as fire grate 17. Need set up burner 22 and guarantee the burning air supply pipe that energy-saving safe moves 20, burning window 21, pre-heating flue seat 9 (seeing Fig. 3), its operation principle are identical during with fire coal with process.

This air conditioner diverse in function, simple in structure, easy for installation, attractive in appearance, thermal efficiency height is to be fit to family, the desirable central cold and warm air-conditioner that subsection uses.

Embodiment: this small-sized central air conditioner is high 1200 millimeters, and is wide 500 millimeters, and dark 650 millimeters, fan delivery 1000m ³/ h, pressure head 150Pa, main material are the hot and cold plate of 1-3 millimeter.10000 kilocalories of heating capacities/time, 120 liters/l of the heat production water yield, 7000 kilocalories of refrigerating capacitys/time, adapted 3P off-premises station and 120L attemperater.
