If 5 water circulating pumps have been broken or there is no current is not start work by current inductor compressor, prevent anhydrous supply condenser heat radiation, the use safety of protection compressor.
6, the New Evaporator that this air-conditioning is used, water refrigerating evaporator and freon refrigeration evaporimeter are the High-efficient Water fluorine double evaporators with hydrophilic membrane that inner screw thread copper pipe unites two into one.
The operation principle of the integrated air conditioner without outdoor unit machine of automatic switchover of two low-temperature receiver refrigerating functions; The operation principle of water system refrigeration is to utilize low temperature well water summer, and in pipeline input air-conditioner, in evaporimeter, the blower fan in air-conditioner, by Indoor Thermal air intake evaporimeter, utilizes thermodynamic principles simultaneously, and exchange heat occurs for the two.In the time of will discharging heat and vaporization (becoming gas from liquid) when air-conditioning is exactly the liquefaction (becoming liquid state from gas) of acquiring in the junior physics of use in fact, to absorb the principle of heat, simultaneously evaporation heat.
When air-conditioning is opened, during water system refrigeration, low temperature well water is extracted out and is entered water fluorine double evaporators 12 by water circulating pump 10 and current inductor 7 through pumping conduit 1, heat due to the fin absorption hot-air on water fluorine double evaporators 12, the hot air temperature that is sucked heat reduces, by induced-draught fan 14 wind pushing air convection current, and be blown into indoor by air outlet 15, coolant-temperature gage after heat absorption raises and enters water condenser 3 refrigerant loses heat to freon refrigeration system and HTHP, by return pipe 2, recharged in another mouthful of well again, so come and go hot-air in circular chamber, constantly by water, absorbed and temperature declines, thereby realize refrigeration object.The natural cold air geothermal air conditioner of water refrigeration system only has water pump and air-conditioning draught fan to consume little power, and Energy Efficiency Ratio 1:25 is the air-conditioning of power saving above.Phreatic water, close to the annual atmosphere mean temperature in locality, has four seasons constant temperature feature cool in summer and warm in winter, affected by atmospheric temperature.In order to obtain lower water temperature, well should not be too shallow also should not be too dark, facts have proved that underground 5 to 30 meters of degree of depth water temperatures are the coolest.30 meters can keep the reason of cryogenic thermostat to be that heat is always upwards rising with interior phreatic water, and cold air is precipitation downwards always, from the sun with from the heat of earth interior, can discharge to atmosphere.The indoor heat that natural cold air geothermal air conditioner absorbs through a summer operation is all absorbed by inverted well surrounding soil, and through returning to original ground temperature again a winter, the ground temperature energy is reproducible natural energy source thus.In summer, directly utilize underground well water circulation to carry out cooling cooling to indoor, because the temperature of phreatic water is throughout the year in 15 ℃ of left and right, after it is extracted from a bite well by water pump, through air-conditioning, be that indoor induced-draught fan 14 send cold wind cooling, then recharging in another mouthful of well at water nonpollution.Neither waste water resource energy-conserving and environment-protective again.Water refrigerant system capacity cannot freeze to require in communication machine room temperature time, computerized control system instruction freon refrigeration system compressor 11 refrigeration of starting working just when computer room temperature surpasses 30 ℃ (this temperature can arrange arbitrarily on request), now refrigeration is more energy-conservation sooner simultaneously for water refrigeration system and freon refrigeration system.Compressor 11 is by the gaseous fluorine Leon of the freon boil down to HTHP of gaseous state, after then high-voltage tube 8 delivers to water condenser 3 heat radiations, become the liquid freon of medium temperature and medium pressure, (by the water that recharges well after water refrigeration system refrigeration, through water condensation heat radiation, getting back to down-hole).Liquid freon is through capillary 5, enter water fluorine double evaporators 12, space increases suddenly, pressure reduces, and liquid freon will be vaporized, (from liquid state to gaseous state, being a process for heat absorption), absorb a large amount of heats, water fluorine double evaporators 12 will turn cold, and the induced-draught fan 14 in air-conditioning blows out indoor air from evaporimeter, so air outlet 15 produces by boasting, is exactly cold wind; Airborne water vapour will condense into water droplet after running into cold water fluorine double evaporators 12, along water pipe, spills out, the reason of air-conditioning meeting water outlet that Here it is.Then the freon of gaseous state is got back to compressor 11 continuation compressions through low pressure muffler 6, and circulation goes round and begins again.Complete refrigeration cool-down in machine room.When in machine room, temperature drops to 28 ℃ (temperature can be set arbitrarily), freon refrigeration compressor quits work, when water refrigeration system works on design temperature, water circulating pump 10 and blower fan 14, compressor 11 quits work simultaneously and plays energy-conserving action, when room temperature is raised to water refrigeration system condition of work, blower fan 14 and water circulating pump 10 start running refrigeration.
The integrated air conditioner without outdoor unit machine of the automatic switchover environment temperature of two low-temperature receiver refrigerating functions is under 39 ℃ of normal service conditions, water refrigeration system work refrigeration just can cool to 28 ℃ the room of 30 square metres of areas, freon refrigeration system very little work refrigeration, so unusual power and energy saving.When two refrigeration systems are freezed without the high-effect air conditioner water refrigeration system of mistress's machine communication base station, do not use freon, floride-free, nontoxic, pollution-free, power consumption equals the power consumption 50W left and right of blower fan, the total power consumption in power consumption 125W left and right that adds water circulating pump only has 175 watts, is current the most a kind of pattern of economical and energy saving.Compare with traditional electric air-conditioning (being the common air-conditioning on market), because it does not adopt compressor and refrigerant-cycle systems, during summer cooling wind, be that water pump and air conditioner fan motor are in electricity consumption, so compare with the power consumption of traditional electrical air-conditioning and save electric energy more than 80% during water refrigeration system refrigeration, its gap is simple, and everybody can draw.When indoor temperature reaches setting value, fan electromotor can shut down automatically.Operation only consumes 4 degree electricity for 24 hours continuously.
The utility model is simple in structure, reasonable in design, and water-cooled and freon refrigeration are combined cleverly, and energy-efficient, automaticity is high, and the power of saving oneself is strong, uses safety, the real the first that belongs to, and the exploitation of this product, will fill up the blank of the domestic and international same industry.
Below in conjunction with accompanying drawing, be described in further detail.
