The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
With reference to Fig. 1-6: the gravity convection radiation air-conditioner; Comprise the compressor 1, four-way change-over valve 2, outdoor heat exchanger 3, throttling arrangement 7 and the indoor heat exchanger 5 that connect and compose the cold-producing medium circulation successively; Be connected with reservoir 4 between said outdoor heat exchanger 3 and the throttling arrangement 7, be connected with gas-liquid separator 8 between said four-way change-over valve 2 and the compressor 1.What the input of cold-producing medium in the above-mentioned indoor heat exchanger 5, output were adopted is heat exchanger tube connector 14.In the utility model, connect compressor 1, outdoor heat exchanger 3, throttling arrangement 7 and indoor heat exchanger 5 through four-way change-over valve 2, thereby the switching-over that realizes cold-producing medium is a prior art, its connected mode is not described in detail in this with reference to Fig. 1, Fig. 2.
Said indoor heat exchanger 5 is lifted on one and leans against in the Gravity Tank 6 of wall setting, and said Gravity Tank 6 is provided with outdoor intake 9, and said outdoor new wind intake 9 passes through body of wall and leads to outdoor.The front of said Gravity Tank 6 is for realizing the metallic plate 13 of radiation refrigeration/heat, and the back side of Gravity Tank is warming plate 11.Metallic plate 13 tops of Gravity Tank are provided with first air port 16, and metallic plate 13 bottoms are provided with second air port 17.Gravity Tank is except above-mentioned new wind intake and first air port, second air port, and other parts are all airtight.Said outdoor new wind intake is opened on the warming plate 11 at Gravity Tank back, on the outdoor new wind intake Electric air valve is housed, and new wind can be realized control automatically through Electric air valve.
In addition, indoor heat exchanger 5 does not contact with the inwall of metallic plate 13, its objective is under refrigerating state, prevents metallic plate because the contact indoor heat exchanger causes the metal sheet surface temperature to cross cold and dewfall.In addition, the effect of warming plate prevents that the interior cold and hot amount of Gravity Tank is through the loss of Gravity Tank back side wall heat transfer.
The bottom of said indoor heat exchanger 5 is provided with the condense water disk 12 of support condensed fluid, and the liquid in the condense water disk 12 is drawn Gravity Tank 6 through condensate drainage pipe 10.
In the present embodiment, said throttling arrangement 7 is an electric expansion valve.In addition, throttling arrangement can also be capillary or heating power expansion valve.
In the present embodiment, said outdoor heat exchanger 3 is finned heat exchanger with indoor heat exchanger 5.
The cooling and warming principle of present embodiment is following:
With reference to Fig. 5, during refrigeration, high-temperature high-pressure refrigerant superheated steam inlet chamber external heat exchanger 3 (as the condensers) that compressor 1 compression is come out; Through air-refrigerant heat exchange, heat is passed to outdoor air, the refrigerant superheat steam of HTHP is condensed into the liquid refrigerant of normal temperature high voltage; Heat exchanger 5 (as evaporimeter) in the inlet chamber after throttling arrangement 7 throttlings; Refrigerant liquid after the step-down is rapid evaporation in indoor heat exchanger 5, absorbs the airborne heat of the indoor heat exchanger 5 of flowing through, and has reduced the surface temperature of the metallic plate 13 of Gravity Tank 6 simultaneously; Metal 13 is through heat in the radiation refrigeration absorption chamber; Cold-producing medium becomes the superheated steam of low-temp low-pressure, is inhaled into compressor 1 and compresses again, so reciprocation cycle.In above-mentioned cyclic process; Indoor heat exchanger 5 ambient airs are owing to the density that is cooled is sunk from second opening, 17 discharges of metallic plate 13 bottoms; Because the effect of air negative pressure; Air gets in the Gravity Tank from first opening 16 on metallic plate top continually, and the indoor heat exchanger 5 of flowing through is cooled, and so the air of Gravity Tank 6 outsides just continues to flow through the indoor heat exchanger 5 of Gravity Tank is cooled after from second opening, 17 discharges of metallic plate bottom; The circulation of formation air-flow has realized the indoor air convection refrigeration.Simultaneously, because metallic plate 13 surface temperatures of Gravity Tank are lowered, formed a cold wall, the effect through radiant heat transfer realizes indoor radiation refrigeration constantly from indoor draw heat.Through above-mentioned cross-ventilation refrigeration and two kinds of refrigeration modes of cold wall radiation refrigeration, realized the high comfortable cooling of indoor noiselessness, ultralow wind speed.
With reference to Fig. 6; When heating, the high-temperature high-pressure refrigerant gas that compressor 1 compression is come out gets into indoor heat exchanger 5 (as condenser), and the refrigerant superheat steam of HTHP is condensed into the sub-cooled liquid refrigerant of normal temperature high voltage; Inlet chamber external heat exchanger after throttling arrangement 7 throttlings; The refrigerant liquid of low pressure is rapid evaporation in outdoor heat exchanger 3, absorbs the heat in the outdoor air source of the outdoor heat exchanger 3 of flowing through simultaneously, becomes the superheated steam of low-temp low-pressure; Be inhaled into compressor 1 and compress, so back and forth.In above-mentioned cyclic process; Indoor heat exchanger 5 ambient airs reduce to rise and discharge from first opening 16 on Gravity Tank 6 tops owing to being heated density; Because the effect of air negative pressure; Air gets in the Gravity Tank from second opening 17 of metallic plate 13 bottoms continually, and the indoor heat exchanger 5 of flowing through is heated, and so the air of Gravity Tank outside just continues to flow through the indoor heat exchanger 5 of Gravity Tank is heated after from first opening, 16 discharges on metallic plate top; The circulation of formation air-flow has realized that indoor air convection heats.Simultaneously, because metallic plate 13 surface temperatures of Gravity Tank are raised, formed a hot wall, the effect through radiant heat transfer realizes that constantly to indoor distribute heat indoor radiation heats.Heat through above-mentioned cross-ventilation and to heat two kinds with hot wall radiation and heat mode, realized high comfortable the heating of indoor noiselessness, low wind speed.
The indoor heat exchanger 5 of present embodiment is the structure of flat, and big with the contact area of air, heat exchange area is big, and its heat exchange area is far longer than the heat exchange area of the finned heat exchanger of common indoor split-type air conditioner; And; Externally there is a large amount of radiant heat transfers in the metallic plate 13 of Gravity Tank; And there is not radiant heat transfer in the common air-conditioning indoor heat exchanger, so the whole heat exchange of the indoor heat exchanger of gravity convection radiation air-conditioner and heat transfer area are far longer than common split-type air conditioner, utilizes the heat exchanger of super large to improve the evaporating temperature when system freezes; Reduced the condensation temperature when heating, so just realized than the existing higher cooling and warming efficient of common cold and hot wind type air-conditioning.
