Description
Technical field
The present invention relates to a kind of comfort type family formula radiator plane air-conditioning assignment of traffic regulating system that is used for; Specifically, relating to a kind of multi-level series-parallel assignment of traffic that is used for comfort type family formula radiator plane air-conditioning radiation end heat exchanger device collects and regulating system.
Background technology
[air-conditioning sensible heat load (cooling) accounts for 50%～70% of total load as a kind of novel control sensible heat in radiation in recent years; And latent heat load (hydrofuge) account for total load 30%～50%] air conditioning mode obtained certain application, have the incomparable advantage of traditional air conditioning mode; Cold fluid (or hot fluid) transfers energy to the radiant panel surface with convection current and radiation through radiant panel; And with the radiation be main mode directly and indoor environment carry out heat exchange; Thereby greatly simplified energy direct energy transfer process from the Cooling and Heat Source to terminal use, reduced irreversible loss; Because radiation has " ultra distance " effect; Can between the surface, directly carry out heat exchange without air; Therefore after various indoor waste heats arrive radiating surface with the mode of shortwave radiation and long-wave radiation; Be converted in the radiant panel and can or pass to the cold fluid and hot fluid that flows in the radiation end heat exchanger, be absorbed and be with from indoor environment through radiant panel heat conduction; This process has reduced the heat exchange link that indoor waste heat is discharged outdoor whole process, and this is that this temperature of radiation cooling is independently controlled the maximum different of end equipment and existing conventional air-conditioning mode.
In radiating system, cold fluid and hot fluid assignment of traffic adjusting device is to be used to connect the confession of radiation end heat exchanger, the distribution of backwater, gathering-device.Be divided into flow distributor, NetStream Collector by advancing backwater.Flow distributor all is assigned to each branch road to the level of trunk line, supplies with corresponding radiation end heat exchanger then, collected the backwater of each branch road again by NetStream Collector, so the assignment of traffic adjusting device has important effect in the radiation refrigeration heat pump.For medium-and-large-sized radiation refrigeration heat pump, because radiation end heat exchanger loop is too much and each loop resistance has big difference, cause the hydraulic misadjustment phenomenon than being easier to, cause the terminal heat exchange poor effect of partial radiation.In addition on the one hand; The loop form that fluid flows in the radiation end heat exchanger has series, parallel and series-parallel connection, and flow regime is mainly turbulent flow, and wherein series system generally need adopt larger-diameter radiation end heat exchanger water supply line; The air that accumulates in the pipe is discharged easily; But pipe-line system can not be oversize, otherwise the SR loss is too big, is in the terminal radiation recuperator of system effectively to bring into play the radiation heat transfer effect; Parallel way generally is used for the radiation end heat exchanger of less branch diameter; Heat exchange efficiency is high; But must be noted that in the design and installation and guarantee that the tube fluid flow velocity is higher that with abundant discharge air, the length of each parallel pipeline is consistent as far as possible; To guarantee that there is identical flow each shunt circuit, guarantee that the import of each shunt circuit has identical pressure with outlet.
The present invention just proposes the multi-level assignment of traffic of a kind of employing and collects adjusting device and connection in series-parallel thereof as radiation end heat exchanger assignment of traffic regulating system; The distribution circuit water yield effectively then; Hydraulic equilibrium in the regulation loop; The discharge balance of assurance system, the heat exchange effect of enhanced rad end heat exchanger, and can bring into play the comprehensive advantage of series-parallel system.
Summary of the invention
The technical problem that the present invention need solve: the present invention is primarily aimed at family formula and medium-sized radiation refrigeration heat pump; Adopt multi-level assignment of traffic regulation technology; Can avoid system because the hydraulic misadjustment phenomenon that cooling and heating load changes, loop is too much and each loop resistance has big difference and causes; Can guarantee flow equilibrium in the radiation end heat exchanger, and make the interior cold fluid and hot fluid of radiation end heat exchanger be in turbulent condition, the heat exchange effect of enhanced rad end heat exchanger; The comprehensive heat exchange effect of raising system reduces system cost.
