In radiation-induced device 1 in said structure, the air-supply outlet of primary side ajutage 13 is connected to plenum chamber 101, static pressure The air outlet of case 101 is connected to the secondary side wind pushing nozzle 103 arranged along air duct blow direction at the top of radiation-induced device.Radiant panel 106 both sides are provided with the induction return air inlet 105 parallel with the direction of primary side air inlet 102.There is parallel baffle plate the top of radiant panel 106 111 spaces formed with the outer wall of secondary side wind pushing nozzle 103, the blast pressure formed by jet expansion can be induced back entering The induction return air in air port 105 is guided to induction mixing chamber 104.When being run by full air mode, First air passes through primary side air intake After mouth 102 enters plenum chamber 101, induction mixing chamber 104 is sent into by secondary side wind pushing nozzle 103, using the air-supply pressure for producing Power induction mixing is cooled down by after the room air for inducing return air inlet 105 to enter induction mixing chamber 104, being exchanged heat with radiant panel 106 Radiant panel 106, while radiant panel 106 is radiated, interior is entered by the rectification after-blow of wind pushing hole 107.Due to air-conditioning at primary side After machine mixing outdoor air and indoor return air, with cold air distribution, air output is reduced, therefore air-supply kinetic energy can be reduced.Secondary side Radiant panel 106 using blast pressure induce room air, sensible heat treatment, plate temperature are carried out by cooling and dehumidifying air auxiliary radiation Being maintained at 19 DEG C of temperature radiate and rectification air-supply.During using Air-Water mixed mode, the method for operation of air side is not Become, chilled water is exchanged heat by being installed on the aluminium heat-exchange coil pipe 108 above radiant panel with radiant panel 106.
Segmented air processes unit 2 after mixing fresh air and indoor return air, and surface cooling section is passed sequentially through by air supply direction 201st, bringing-up section 202, humidifier section 203, the blast pressure provided by fan section 204 get in end.Under indoor location has Square return air inlet 11 and top return air inlet 10, indoor return air deliver to the mixing section mixing chamber of air processor 2 by negative pressure section blower fan 15 Outer fresh air.The radiation-induced device 1 of indoor location, chilled water can be by the band fin aluminium heat-exchange coil pipe that is installed on above radiant panel 108 exchange heat with radiant panel 106.The surface cooling section and the coil pipe of radiation-induced device of double evaporators handpiece Water Chilling Units 3 and air-treatment unit 2 Between by pipeline connect.Indoor location has top return air inlet 10 and lower section return air inlet 11, and return air delivers to air by negative pressure section Mix fresh air in treatment unit mixing section.
High temperature bushing type evaporator 301 in double evaporators handpiece Water Chilling Units 3 is that indoor end radiation is lured by water circulating pump 9 Lead device 1 and chilled water is provided, low-temperature casing formula evaporator 302 is that segmented air processes the offer freezing of unit 2 by circulating pump 6 Water.Under the operating mode for there are dehumidification requirements, provided at cryogenic freezing water to segmented air by two series operations of evaporator Reason unit 2, produces supercooling air, sends into radiation-induced device 1 and is run using full air mode.Using the sky for effectively preventing condensation During gas+water mixed running pattern, by two parallel runnings of evaporator respectively to air-treatment unit and radiation-induced device Coil pipe provides chilled water.When load is smaller, two evaporators can isolated operation.
In the present invention, due to air conditioner mixing outdoor air and indoor return air at primary side after, with cold air distribution, reduce Air output, therefore air-supply kinetic energy can be reduced.Radiant panel 106 induces room air using blast pressure, by cooling and dehumidifying air Auxiliary radiation carries out sensible heat treatment, and the temperature that plate temperature is maintained at 19 DEG C radiate and rectification air-supply.
This patent is using radiation-induced device 1 as indoor end.During using full air mode, from segmented air treatment After the First air of unit 2 enters plenum chamber 101 by primary side air inlet 102, sent into by secondary side wind pushing nozzle 103 and induced Mixing chamber 104, the interior of induction mixing chamber 104 is entered using the blast pressure induction mixing for producing by inducing return air inlet 105 Air, exchanges heat with radiant panel 106, after cooling radiant panel, while radiant panel is radiated, is blown into by after the rectification of wind pushing hole 107 It is indoor.The characteristics of induced draught mode, is at primary side after air conditioner mixing outdoor air and indoor return air, with cold air distribution, Air output is reduced during treatment latent heat, therefore air-supply kinetic energy can be reduced.The radiant panel of secondary side is using in blast pressure induction room Air, sensible heat treatment is carried out by cooling and dehumidifying air auxiliary radiation, and the temperature that plate temperature is maintained at 19 DEG C radiate and rectification Air-supply.During using air+water mixed mode, the method for operation of air side is constant, and chilled water is by being installed on above radiant panel Aluminum band finned coil (108) exchanges heat with radiant panel.
Indoor location has lower section return air inlet 11 and top return air inlet 10, and indoor return air delivers to segmentation by negative pressure section blower fan 15 The mixing section of formula air-treatment unit 2 mixes outdoor fresh air.
Further, two described induction return air inlets 105 are along the symmetrical laying of the first mixing chamber 104.Two induction return air inlets 105 symmetrical layings, when installation of ceiling Room air distribution design and Temperature Distribution can be more uniformly distributed.
